9e81ddee87 * Fixed fdopendir(): We have to explicitly (re-)open the directory, because FDs
returned by open() aren't suitable for directory iteration and because checks
  have to be performed (like whether this is a directory at all and whether the
  user has read permission).
* Added __create_dir_struct() for the attribute, index, and query open
  functions to use instead.

ecf6b86c92 * The pthread_thread structure is now allocated for all threads.
* Therefore, all pthread functions should now work fine on all threads.

7249de5e61 * Changed the affine scheduler to have more or less the same characteristics
as the BeOS scheduler. This makes MediaPlayer playback much better, as high
  priority threads could lose their quantum to a worker thread twice in a row
  with 4% probability before.
* I did not yet change the simple scheduler as well yet; maybe this isn't the
  final one either.

a0439d88df * Adjusted thread priorities of several system services based on a mail from
Mikhail Panasyuk: since worker threads often end up with B_NORMAL_PRIORITY,
  it might be a good idea to give system threads a higher priority.
* Minor cleanup (mostly automatic whitespace).

6242fd5977 * Added the possibility to debug latency issues with spinlocks.
* When DEBUG_SPINLOCK_LATENCIES is 1, the system will panic if any spinlock is
  held longer than DEBUG_LATENCY micro seconds (currently 200). If your system
  doesn't boot anymore, a new safemode setting can disable the panic.
* Besides some problems during boot when the MTRRs are set up, 200 usecs work
  fine here if all debug output is turned off (the output stuff is definitely
  problematic, though I don't have a good idea on how to improve upon it a lot).
* Renamed the formerly BeOS compatible safemode settings to look better; there
  is no need to be compatible there.

8665c30ace That was not such a good destruction order in the error case. As the scheduler
accesses the scheduler data inside the thread structure, freeing it first lead
to a crash when a thread couldn't be created.

13ce48d922 * Moved dprintf_args()/debug_puts() guts to a new dedicated private function
debug_output().
* Added a second buffer to be used when interrupts are turned off, otherwise
  dprintf_args() will now use a mutex guarded buffer to fill with vfprintf() -
  the actual sending to the outputs still needs the spinlock, so things only
  slightly improved.
* Moved private functions into the private section of the source file.

  to scan the entire semaphore table.

  KDEBUG=2) on my laptop.

3530c3eb6b * Reimplemented the insane _get_next_thread_info() which previously just
iterated over all known thread *IDs* with interrupts disabled.
  Now it iterates over the team's thread list (going from back to front, since
  new threads are added at the front of the singly linked queue).
* Alexandre restarted Tracker quite a lot, and let the shell script run to
  reproduce a certain bug - and then wondered why ProcessController would
  take several seconds to open its windows until it passed through more than
  8 million IDs... :-)

f28dd36b82 * The alphabet is obviously hard, moved some tracing defines at their
(hopefully) correct place.
* It seems to be even harder to understand basic locking primitives: when you
  think about it, it shouldn't surprise you that conditional variables never
  return B_WOULD_BLOCK. This fixes gdb again.
* Added tracing support to the ports subsystem.
* get_port_message() will now resize the port heap if needed (but will also
  take timeouts into account while doing so, more or less). The initial port
  space is 4MB (as before), the growth rate is the same, and the system wide
  limit is arbitrarily set to 64 MB (all swappable). A team limit has been set
  to 8 MB, but is not enforced yet. Since ports are using up address space in
  the kernel, those seems to be proper limits.
* This also fixes a strange, and rare lockup where the mouse cursor would still
  move, but everything else would basically hang, but look perfectly normal from
  KDL on the first look. As recently happened on Brecht's laptop, and debugged
  by mmlr and me: the cbuf space got used up when lots of windows wanted to
  redraw after a workspace switch. The app_server wouldn't answer anymore to
  client requests, but thought it would have done so, as LinkSender::Flush()
  doesn't care if it got a B_NO_MEMORY (the ports will now block until memory
  is available if possible, so that should not be a problem anymore).
* Improved "port" KDL command, it now also prints the messages in the port.

5c056f9f10 * set_port_owner() was the only usable call of the port API, and of course it
was used this way in the debugger. Doing this later should be harmless,
  AFAICT, but Ingo will probably know better.
* Beware, though, the debugger currently does not work anymore.

Axel Dörfler
e8885f2097 Basically rewrote the ports subsystem to use:
* its own heap allocator instead of cbuf - this makes cbuf superfluous, and I
  therefore removed it from the kernel. The heap is swappable, so lifts the
  kernel's resource usage a bit. In the future, the heap should grow as well;
  right now it should be at least as good as before.
* it no longer uses spinlocks, but just mutexes now for better scalability - it
  was not usable with interrupts turned off anyway (due to its semaphore usage).
* it no longer uses semaphores, but condition variables.
* Needed to move the port initialization to a later point, as swappable memory
  wasn't usable that early.
* All ports test are still passing, hopefully I didn't mess anything up :-)

6bb413270b The allocation size wasn't updated on an area based realloc that would still
fit into the existing area. In that case further reallocs could then assume the
wrong previous size and then not copy enough from the original buffer, leading
to lost bytes at the end of the new buffer.

  try to allocate a negative amount of memory we could overflow and crash

* Review and update the alignment logic which was a bit broken for the huge
  allocation case (reaching the area threshold). Also assert the results so
  next time this will be easier to spot.

as the one from libkernelland_emu but uses a mutex per lock instead of emulating
a global thread lock. Also added MutexLocking and RWLock{Read|Write}Locking and
AutoLockers based on them. It's cased with __cplusplus so the locks are also
usable from C. Everything's currently exposed in shared/private/locks.h but I
think we should make these locking primitves public.

7a4d60459e Implement combining scattered physical pages using seperate iovecs in
PageWriteTransfer. This makes the transfer accept virtually contiguous pages,
where the offset is contiguous on either end of the current transfer, but where
the pages aren't physically contiguous. It will then add seperate iovecs for
these pages (32 at max right now). This reduces the number of IO requests
generated and allows for optimizations down the IO path (like in the physical to
virtual mapping case for example).

32e2b6a118 Provide a way to directly request virtual vecs from an IOBuffer. If the buffer
is virtual already it just returns the vecs directly, if it is physical it takes
over the task of virtualizing the vecs either using vm_map_physical_memory_vecs,
if there are multiple vecs or more than one page, or falls back to page wise
mapping if mapping fails or is not needed. In the best case, scattered physical
pages are mapped into one linear virtual buffer so that subsystems operating on
virtual memory only get a single vector and can then burst read/write.

is a private API right now, but we might want to make it public as
map_physical_memory_vecs alongside map_physical_memory.

1af7d11504 * Rework page writing to combine page writes where possible. For now the pages
are required to be physically contiguos, which should be reworked to put them
  into seperate iovecs. Still this manages to combine a great deal of page
  writes into larger bursts already. Reduces the amount of IO requests being
  scheduled (and greatly benefits media where page wise writes are slow when
  they are accessed through a non-IOScheduler path, i.e. USB mass storage until
  that is properly implemented).
* Abstracted per page page writing tasks into a PageWriteWrapper class.
* Abstracted per transfer page writing tasks into PageWriteTransfer class which
  formerly was the PageWriterCallback.
* Use both classes from the PageWriterRun and from
  vm_page_write_modified_page_range to remove code duplication.
* Adjusted synchronous VMAnonymousCache::Write() to cope correctly with larger
  iovecs and more than one iovec. It assumed that there was exactly one page per
  vector previously.
* Introduced MaxPagesPerWrite() and MaxPagesPerAsyncWrite() to VMCache to allow
  a cache to specify restricitions. VMAnonymousCache does restrict the max pages
  to 1 for WriteAsync right now as I didn't feel like reworking that one to cope
  with non single page writes just yet.
* Pulled out PageWriteTransfer methods for better readability.
* Some typo fixes.

f3bd145c09 When the need for physical to virtual mapping arises because of emulating IO
reads or writes for old style drivers, map the physical memory at once. Since
USB is pretty much the only one affected and there small reads/writes are
exponentially slower, the performance gain of the burst transfer far outweighs
the additional overhead of the mapping. Still this could be further optimized
and will eventually be superseeded by also providing a physical memory API in
USB. For now it should bring back USB reads to an acceptable level. Writes are
still page wise though because of how writing back memory works in general.

- Fixed vfs_get_vnode_from_fd() return type.
  - Added vfs_open_vnode().
  - Added a "bool traverseLeafLink" parameter to vfs_get_fs_node_from_path().
    It was always resolving symlinks.
* device manager/devfs:
  - devfs: get_node_for_path() no longer resolves leaf symlinks. That still
    doesn't help with file disk devices, as creating partition wouldn't work
    anyway.
  - Pulled the module-related implementation part of BaseDevice into new class
    AbstractModuleDevice and made all methods of BaseDevice virtual. Small
    adjustments to devfs to be happy with the new BaseDevice interface.
  - Added BaseDevice subclass FileDevice, which maps the interface to a file's
    file descriptor. Still got a few TODOs, but should basically work.
  - Use FileDevice for publishing file disk devices in devfs. Now those do
    actually work, though there's some BFS trouble with one of the images I
    tested.

8626c1aa5f the HPET timers resolution is REALLY high. The time conversion was off by
1000. XenServer boots correctly and in reasonable time,
now (meaning hpet timers work). I guess on real hw the bios doesn't
correctly program the hpet timers, so we'll need a bit more work.

1bcca32a9e * Also take into account that the alignment due to B_ANY_KERNEL_BLOCK_ADDRESS
can cause overflows.
* Added a generic IS_VALID_SPOT() macro that checks for overflows and checks if
  the area will fit with the given constraints.
* Use the macro to simplify the places where these checks are necessary.
* Use the provided "end" limit instead of the address space end. It currently
  doesn't matter but makes more sense.
* Rename newBase variables to alignedBase as that's what they are.

e717a35b6f * Change the way we check for enough available space when searching for spots
to insert areas so we don't overflow.
* Consequently use the area end (base + size - 1) where appropriate which
  prevents overflows in a few places.
* Properly check for reaching the address space end.
* If we've already found a spot we don't need to recheck if we've found one.
* Simplify the B_EXACT_ADDRESS checks down to a simpler single if statement
  instead of the four seperate ones.
* Properly calculate the search end for B_EXACT_ADDRESS as well, it's also
  base + size - 1.
* Block the full last page now that this actually works without overflowing.
* Some style changes and added spacing.

This should now really fix #2550. Previously the overflow protection didn't
actually work because on allocation we overflowed and completely missed the
protecting area.

65b5e4d7ed Make use of the address range blocking to guarantee that accessing 0xdeadbeef
and 0xcccccccc (and 64 pages thereafter) in any way will always lead to a crash.
Before it could happen that these ranges were allocated for an area and then
accessing these would not be as evident anymore. Only enabled when the
corresponding paranoid setting is enabled (which it currently is).

9aff7f1593 Block the very last page of kernel address space. The problem here is that non
of the VM functions handling areas are overflow safe. If an area is created that
spans across the last page many places will run into an integer overflow. This
mostly concerns the area allocation path in find_and_insert_area_slot() and also
vm_create_anonymous_area() where the loop for mapping pages for B_FULL_LOCK
areas overflows and runs more times than it should leading to #2550.
This could be seen as a workaround. The real fix would be to make everything
overflow safe. The thing is that this does also concern the user of the area
which could easily have forgotten to check for overflows as well, so I am a bit
uneasy with handing out areas that could easily lead to such hard to debug
problems. Since this is really an edge case and this single step safes quite a
bit of extra checks I'd actually be OK with keeping it that way.

185fd1c5d2 Ported over the kernel heap to libroot to make use of it's validation
capabilities to aid in debugging memory corruption issues.

It does:
* Initialize memory to 0xcc to help turn up use of uninitialized memory
* Set freed memory to 0xdeadbeef to help find accesses of freed memory
* Use the paranoid heap validation to turn up many cases of memory corruption
* Use a simplistic wall check to turn up memory overwrites past allocations
* Take extra steps to validate freed addresses to turn up misaligned frees

It has an interface to en-/disable paranoid validation and to start/stop regular
wall checking. Both are currently just enabled. At a later stage a debug version
of libroot could be used by an application and the checks enabled at will. Note
that due to the paranoid validation and the suboptimal locking this allocator
will perform horribly. Still to find memory corruption issues in the system or
also in your applications it can be helpful to build your installation with it
turned on. To enable it you currently need to edit the Jamfile to sub-include
the malloc_debug instead of the malloc directory.

419f2d6f3e Fix errors in maintaining the area list due to assumptions that are only true
for the page list but not the area one. Since multiple pages can be allocated
at once, even an area that is not at the top of the list can become empty. In
such a case the area list would previously have lost entries. Also because
we can remove more than one page from any area, not just the top one, we may
need to move forward in the list so that it stays ordered by free pages.

92e143c14a Fix regression introduced in r32526: registering the device watcher for node monitoring needs to happen synchronously, otherwise a race condition occurs: unless you're very lucky, the event for creating the raw device would happen before the async thread had a change to add the node monitor, and as such the listener would miss it, and never trigger a filesystem/partition scan. As a result, whether or not adding a USB stick would actually show a volume was essentially russian roulette. Fixes ticket #4345.

8c5ad61d4b * Prevent the /boot entry from ever being renamed. You couldn't even try to
switch /boot to a different volume in two operations, unless you have first
  linked /system/lib into /bin. This patch assumes that / will always have the
  ID 1. Don't know if that is proper. Note that I also thought about solving
  this in the VFS, since perhaps it isn't the job of root-fs to know about
  /boot, but that would of course introduce another check for every rename
  operation, which I decided against.

89294b5084 * Added option for enabling serial debug output.
* Moved device_manager/settings.cpp to debug/safemode_settings.cpp.
* Removed the somewhat hacky concatenation of kernel settings and safemode
  settings in the boot loader. Instead, get_safemode_option() will now fall
  back to the kernel settings, if it couldn't spot a setting in the safemode
  settings. This allows for more control, and also makes enabling serial
  debug output actually work (ie. overriding the kernel settings via safemode
  options).
* Adjusted debug_init_post_vm(), and smp_init_other_cpus() to use
  get_safemode_boolean().
* Therefore, I added safemode_settings.cpp to the boot loader as well.

There are probably other places in the kernel that could now make use of that information to more intelligently call reschedule() though.

* Keep track of the currently running threads.
* Make use of that info to decide if a thread that becomes ready should preempt
  the running thread.
* If we should preempt we send the target CPU a reschedule message.
* This preemption strategy makes keeping track of idle CPUs by means of a bitmap
  superflous and it is therefore removed.
* Right now only other CPUs are preempted though, not the current one.
* Add missing initialization of the quantum tracking code.
* Do not extend the quantum of the idle thread based quantum tracking as we want
  it to not run longer than necessary. Once the preemption works completely
  adding a quantum timer for the idle thread will become unnecessary though.
* Fix thread stealing code, it did missed the last thread in the run queue.
* When stealing, try to steal the highest priority thread that is currently
  waiting by taking priorities into account when finding the target run queue.
* Simplify stealing code a bit as well.
* Minor cleanups.

level as before. Didn't cause any real damage, guess it was just an oversight.

57dc0e2a53 Changed the FD selection/deselection handling a bit:
* B_EVENT_INVALID is no longer passed to the FD's select()/deselect() hooks.
* Now we always attach the select info to the I/O context, even if no event has
  been selected. The reasoning is that B_EVENT_INVALID is always automatically
  selected and handled by the VFS, so we need the handle to notify on close().

This seems to work around the dynamic segment having a huge file size in headers, it must also be in the data segment...

bb693d7764 * Added VESA capabilities field to the kernel args.
* The vesa driver no longer uses VGA programming if the chip does not support
  VGA compatibility.
* The VESA driver now tries to set the DAC to 8 bits per color gun.
* In VESA modes, the driver no longer tries to use VGA programming; introduced
  the new vesa_set_indexed_colors() that is now used for palette programming.
  This should fix wrong colors of 8 bit BWindowScreen users with VESA on real
  hardware (emulators usually didn't mind either way).
* Note that the app_server needs to maintain a palette per 8 bit screen, as
  right now, the colors are garbled after a workspace switch. Stefano, are you
  looking into that already?

- made devices.cpp use them to publish the MemoryDisk,
- add an haiku_loader_nbsd.ub target which puts both the loader and kernel_arm for now (need to replace with the tgz).

- consolidate board specific definitions into build/jam/board/*/BoardSetup to avoid duplicating address values everywhere,
	- add various addresses, boot script, custom C/C++ flags and SD card definition,
	- not sure BoardSetup is included at the best place though,
	- replaced board-specific ldscript with passing the loader address directly to LD from BoardSetup,
- added haiku.mmc target which generates an mmc/SD card image with a FAT partition with the files needed to boot for the board, should later be integrated with haiku.image with the BFS partition offset passed to bfs_shell, requires apt:sfdisk,mtools on GNU/Linux,
- added some more rules, one to build a script for the SD image,
- fake a NetBSD loader for now, U-Boot doesn't know haiku, and we'll need a way to pass the tgz image and RAM size, we'll either use standlone way (usual C argv[]) or the NetBSD args,
- style fixes,
- 80 cols, /me pets Ingo.

50d22f83ef The reference of the currently active translation map shouldn't be released
until the data it protects isn't in active use anymore. Previously it would
release the translation map and therefore the page directory reference while
the page dir was still set on the CPU, as only the actual call to
i386_context_switch() will replace the page directory in the control register.
This didn't cause any harm though, as during the context switch interrupts are
disabled and therefore the page directory would only be deferred_delete()ed and
not directly freed/overwritten. Still this is logically more correct.

86766d6aca * handle_driver_events() kept the sDriversListLock locked over the whole
time. But since this is also locked from within the driver/directory watcher
  (with the node monitor lock held), and handle_driver_events() could cause
  node monitoring updates, the locking order could be reverted, causing a
  deadlock (I just ran into).

ee280b59e9 Prevent the user TLB invalidation function from being preempted by turning off
interrupts when invoking it. The user TLB invalidation function essentially only
reads and writes back control register 3 (cr3) which holds the physical address
of the current page directory. Still a preemption between the read and the write
can cause problems when the last thread of a team dies and therefore the team
is deleted. The context switch on preemption would decrement the refcount of the
object that holds the page directory. Then the team address space is deleted
causing the context switch returning to that thread to not re-acquire a
reference to the object. At that point the page directory as set in cr3 is the
one of the previously run thread (which is fine, as all share the kernel space
mappings we need). Now when the preempted thread continues though, it would
overwrite cr3 with the physical page directory address from before the context
switch still stored in eax, therefore setting the page directory to the one of
the dying thread that now doesn't have the corresponding reference. Further
progressing the thread would release the last reference causing the deletion
of the object and freeing of the, now active again, page directory. The memory
getting overwritten (by deadbeef) now completely corrupts the page directory
causing basically any memory access to fault, in the end resulting in a
triplefault. This should fix bug #3399.

56c6c0fefb - introduced an "argumetns" field in stage2_args to hold command line args from chaining loader,
- added some multiboot support code:
	- dump some of the passed info,
	- parse command line (skip the 'kernel' name and pass the rest to stage2_args.arguments),
- added an add_stage2_driver_settings() function which takes stage2_args.arguments and translates it into safe mode driver settings, a bit dumb for now.
This allows using qemu -kernel haiku_loader -append 'debug_screen true' and get debug output without having to enter the menu (once multiboot info is used to determine the boot device too).
The idea is to allow passing driver settings and using them to pass extra stuff (like 'force_keymap fr' and other stuff for demo), and to help automate tests ('run_test /bin/sometest').
This should answer Axel's question :)

255c9104e5 * Rework the heap locking strategy. Use a read-write lock for the area lock to
allow for more parallelism. Also introduce seperate locks for the bins and
  for page allocation. This greatly reduces lock contention and reduces the
  duration the locks are held due to them overall protecting less code. Now only
  allocations of the same size hitting the same allocator or allocating larger
  chunks of memory should block. Previously, basically any allocation and also
  free would be mutually exclusive, making it scale pretty badely.
* Added memalign_nogrow(). As it uses heap_memalign() anyway, there's no real
  reason not to allow for an alignment.
* Some cleanup.

ea2abd110b * Renamed the ROUNDOWN macro to ROUNDDOWN. Also changed the implementation of
ROUNDUP to use '*' and '/' -- the compiler will optimize that for powers of
  two anyway and this implementation works for other numbers as well.
* The thread::fault_handler use in C[++] code was broken with gcc 4. At least
  when other functions were invoked. Trying to trick the compiler wasn't a
  particularly good idea anyway, since the next compiler version could break
  the trick again. So the general policy is to use the fault handlers only in
  assembly code where we have full control. Changed that for x86 (save for the
  vm86 mode, which has a similar mechanism), but not for the other
  architectures.
* Introduced fault_handler, fault_handler_stack_pointer, and fault_jump_buffer
  fields in the cpu_ent structure, which must be used instead of
  thread::fault_handler in the kernel debugger. Consequently user_memcpy() must
  not be used in the kernel debugger either. Introduced a debug_memcpy()
  instead.
* Introduced debug_call_with_fault_handler() function which calls a function
  in a setjmp() and fault handler context. The architecture specific backend
  arch_debug_call_with_fault_handler() has only been implemented for x86 yet.
* Introduced debug_is_kernel_memory_accessible() for use in the kernel
  debugger. It determines whether a range of memory can be accessed in the
  way specified. The architecture specific back end
  arch_vm_translation_map_is_kernel_page_accessible() has only been implemented
  for x86 yet.
* Added arch_debug_unset_current_thread() (only implemented for x86) to unset
  the current thread pointer in the kernel debugger. When entering the kernel
  debugger we do some basic sanity checks of the currently set thread structure
  and unset it, if they fail. This allows certain commands (most importantly
  the stack trace command) to avoid accessing the thread structure.
* x86: When handling a double fault, we do now install a special handler for
  page faults. This allows us to gracefully catch faulting commands, even if
  e.g. the thread structure is toast.

We are now in much better shape to deal with double faults. Hopefully avoiding
the triple faults that some people have been experiencing on their hardware
and ideally even allowing to use the kernel debugger normally.

Based on a patch from Dustin Howett, reworked, and help from Vladimir 'phcoder' Serbinenko.
- used defines for clarity, the rest of teh code could make use of them too...
- added a gMultiBootInfo pointer to the passed args, to let C code handle it instead of faking the boot drive ID,
- conditionalized the copy back, maybe we can get rid of it when QEMU handles our default load address correctly,
- added video mode info to ask for 1024x768 but QEMU ignores it anyway, and we might need to show the menu, so it's disabled.

671a2442d9 More work towards making our double fault handler less triple fault prone:
* SMP:
  - Added smp_send_broadcast_ici_interrupts_disabled(), which is basically
    equivalent to smp_send_broadcast_ici(), but is only called with interrupts
    disabled and gets the CPU index, so it doesn't have to use
    smp_get_current_cpu() (which dereferences the current thread).
  - Added cpu index parameter to smp_intercpu_int_handler().
* x86:
  - arch_int.c -> arch_int.cpp
  - Set up an IDT per CPU. We were using a single IDT for all CPUs, but that
    can't work, since we need different tasks for the double fault interrupt
    vector.
  - Set the per CPU double fault task gates correctly.
  - Renamed set_intr_gate() to set_interrupt_gate and set_system_gate() to
    set_trap_gate() and documented them a bit.
  - Renamed double_fault_exception() x86_double_fault_exception() and fixed
    it not to use smp_get_current_cpu(). Instead we have the new
    x86_double_fault_get_cpu() that deducts the CPU index from the used stack.
  - Fixed the double_fault interrupt handler: It no longer calls int_bottom to
    avoid accessing the current thread.
* debug.cpp:
  - Introduced explicit debug_double_fault() to enter the kernel debugger from
    a double fault handler.
  - Avoid using smp_get_current_cpu().
  - Don't use kprintf() before sDebuggerOnCPU is set. Otherwise
    acquire_spinlock() is invoked by arch_debug_serial_puts().

Things look a bit better when the current thread pointer is broken -- we run
into kernel_debugger_loop() and successfully print the "Welcome to KDL"
message -- but we still dereference the thread pointer afterwards, so that we
don't get a usable kernel debugger yet.

cc77aba101 * Allocate a separate double fault stack for each CPU.
* Added x86_double_fault_get_cpu(), a save way to get the CPU index when in
  the double fault handler. smp_get_current_cpu() requires at least a somewhat
  intact thread structure, so we rather want to avoid it when handling a double
  fault. There are a lot more of those dependencies in the KDL entry code.
  Working on it...

c32499b4f7 * Since the file_map reports its chunk with a file system specific alignment, we
cannot assume that the file is that long - we need to check for the actual

* This fixes seeing old file left-overs in the space beyond the file size in
  mmapped file. Thanks to Oliver who provided me with a nice test program to
  reproduce this problem (this should also fix gcc's fix_includes app (although
  I wonder what it does if a file actually ends on a page boundary).
* Also fixed a bug in precaching that would cause the last page of the cache
  to be discarded, causing it to be re-read later on.
* Moved partial page clearing into its own function
  read_pages_and_clear_partial(), even though it's currently only used once.

5147963dcd headers/private/kernel/util/OpenHashTable.h, Hugo's version, is a bit nicer than
Tracker's OpenHashTable.h which it should eventually replace. We've renamed the

became superfluous.
Adapted all the code that used it. Since the OpenHashTables no longer clash,
this should fix the GCC4 build.

0b11ecb18c * Always include the public arch_debugger.h headers. The structures defined
there are prefixed with the respective architecture name. Useful for remote
  debugging a different architecture.
* <x86/arch_debugger.h>: Introduced a structure for the FPU state, so that it
  isn't left to the debugger.
* Removed the _kern_get_thread_cpu_state() syscall. Was originally intended for
  bdb compatiblity, but isn't really needed.
* Kernel x86 arch_get_debug_cpu_state(): The use of fnsave was broken, since
  it reinits the FPU after saving the state. This resulted in weird results
  when debugging functions using the FPU. We now use fxsave, if available.
  Otherwise fnsave + frstor should be used -- not fully implemented yet.
  Same for arch_set_debug_cpu_state().

c755ecfe96 * Added an emergency key mechanism to the kernel, inspired by Jan Klötzke's
patch from about a year ago (I couldn't use any code of his yet, though,
  but there are a few things left). The emergency keys are triggered by
  pressing Alt-SysReq + key.
* By default, only Alt-SysReq+'d' is used as a means to deliberately enter
  the kernel debugger. F12 belongs to userland again, now :-)
* Debugger add-ons now have another optional method to implement their own
  emergency keys - 'd' for the debugger cannot be overridden, though.
* The mechanism can be turned off via a new kernel setting, so it's not that
  easy anymore to "crash" Haiku if you don't want to.
* Right now, the PS/2 driver, and the pre-input_server in-kernel debugger
  keyboard mini-driver support this, USB not yet.
* Minor cleanup.

* Added BPartitionParameterEditor interface, which is/will be used for editing

* Implemented partition parameter editors for BFS initialization and Intel

* Fixed the incorrect supported child partition type iteration in the Intel
  partition map add-on. It does now return actual types.
* Handle the "active" flag parameter in the Intel partitioning system module.
* DriveSetup:
  - Replaced the "Create" submenu by a simple menu item. The type can now by
    chosen in the dialog.
  - Make use of initialization and child creation parameter editors. Some
    non-generic code has been moved to the respective editor implementations
    (BFS, intel partitioning system).

  iterator (and also adds the boot kernel path, in case the module don't have

a365e1cfbb Patch by Bryce Groff, some changes by myself:
* devfs:
  - devfs_[un]publish_partition(): They no longer get the partition path as
    parameter, but rather the device path and the partition name.
  - Added devfs_rename_partition(), which renames an already published
    partition node.
* KPartition/KDiskDevice:
  - Replaced the fPublished flag by fPublishedName, the name under which the
    partition is published. This simplifies UnpublishDevice() and makes it
    practically infallible.
  - Added GetFileName(), which only returns the partition's file name.
    Simplified GetPath() by using it.
  - When a partition is added/removed the subsequent sibling partitions get a
    new index. Now we also rename their published device nodes (and those of
    their descendents). When something goes wrong we unpublish the concerned
    partition's device to be on the safe side. Would be a shame to accidentally
    format the wrong partition, eh? :-)

be1f4fe800 * find_symbol_breadth_first() didn't ever set _foundInImage, although
it's signature indicates that it should - the callers just never use
  the value currently, so it caused no harm
* squashed a TODO in the runtime_loader about the resolving strategy
  for undefined symbols in add-ons: I've implemented the breadth-first
  strategy (leaving out the add-on itself), as that one made most sense to
  me.
This avoids loader problems with older optional packages of Pe on gcc4, as some
add-ons (e.g. "Expand Tabs") could not be loaded due to them containing undefined
symbols that are found in second level dependencies (libstdc++.so in this case).

Ingo: please review.

  no longer fail in case there was no timezone symlink before.
* Cleaned up OS.h header.

181593ba0b * Properly document why fs_write_attr() does what it does.
* As even the author of fs_attr.c was trying to use fs_write_attr() in an
  unsupported way in the cp copy_attributes() implementation, try to be
  more forgiving and support writing attributes at an offset. The method is
  required to behave inconsistent in that replacing bytes at offset 0 is
  not supported as replacing bytes at any other offset. Writing at offset 0
  will clobber the existing attribute to stay compatible with BeOS.

NOTE: BFS itself still does not support writing attributes at an offset which
are withing the "small data section". To work around this problem, programs
which copy attributes in a loop must make sure that their buffer is large
enough that such "small data section" attributes require only one loop
iteration.

e0965f2727 * reload_driver() now also checks if the binary node changed, and will update
the node listener, to make sure it won't lose track.
* The DriverWatcher now also listens for B_ENTRY_REMOVED. This causes drivers to
  be unpublished even if they are only symlinked.
* However, to detect new drivers in a symlinked location, we'd need special
  support for those, and also need to watch the parent directory of the symlink
  target - this is close to overkill, so I stayed away from implementing that
  for now :-)

  watchpoints, and memory reads/writes -- is done in the new class
  BreakpointManager.
* For the architectures a few capability macros have to be defined, one
  pointing to the software breakpoint instruction opcode. Done for x86.
* Some more simplifications in the user debugger code, made possible by the
  recently introduced debugger_changed_condition attribute.

* It was broken since the support for debugger handovers. Using
  debugger_write() couldn't work, since the thread didn't belong to the
  debugged team anymore (but to the kernel) and thus getting the debug info
  for team would always fail. This makes B_DEBUGGER_MESSAGE_THREAD_DELETED
  notifications work again.
* Allow the thread to block. Locking/writing to the port was non-blocking
  before, but there shouldn't be a problem, if the thread has to wait.

568ade58d0 User debugger support:
* Generalized address checks. The debugger can now also read the commpage.
* Added new syscall _kern_get_thread_cpu_state() to get the CPU state of a
  not running thread. Introduced arch_get_thread_debug_cpu_state() for that
  purpose, which is only implemented for x86 ATM (uses the new
  i386_get_thread_user_iframe()).
* Don't allow a debugger to change a thread's "esp" anymore. That's the esp
  register in the kernel. "user_esp" can still be changed.
* Generally set RF (resume flag) in eflags in interrupt handlers, not only
  after a instruction breakpoint debug exception. This should prevent
  breakpoints from being triggered more than once (e.g. when the breakpoint is
  on an instruction that can cause a page fault). I still saw those with bdb
  in VMware, but that might be a VMware bug.

f835a75f31 Make two runs of MTRR setting when setting memory ranges to write-back. At the
first run only set up uncacheable MTRRs and in the second run set the write-back
ones up. If this order is not followed, we could set too large ranges to
cacheable first and then limit it back to uncacheable later. On systems with
enough physical memory this would lead to a temporary situation in which areas
become cacheable that must not be, resulting in system hangs or other unexpected
behaviour. Fixes last part of #4018.

eb0262fc4c * Reworked vm_soft_fault() and friends:
- While walking down the cache chain, we keep all upper caches locked.
  - When we have to unlock -- when waiting for a busy page or reading a page in
    -- we unlock completely, including the address space, and restart
    vm_soft_fault().
  - Folded fault_get_page() and fault_find_page() into one.
  This simplifies and improves things considerably:
  - We no longer need dummy pages.
  - We no longer need vm_area::no_cache_change.
  - #2710 is fixed, since we no longer hold the address space lock while
    waiting.
* vm_soft_fault(): When we have found our page, we first check whether a page
  is already mapped at the address. If it is already our page, we just change
  its protection. If not, we unmap it first. Fixes race conditions when multiple
  threads fault at the same address at the same time.
* fault_get_page(): When copying a read-only page from a lower cache, no longer
  mark it active, since at least for the fault area it is shadowed from then on.
* vm_set_area_protection(): Fixed potential overflow for in the
  vm_translation_map::protect() call.

  (as stat_beos) and conversion functions
* Introduced versions for [l,f]stat().
* Added symbol versions for BDirectory::GetStatFor() for sake of binary
  compatibility.
* BStatable::GetStat(): Renamed the old method, changed its parameter to
  stat_beos*, and and made it private. Added a new version (using up a

* BRefFilter::Filter(): Changed the struct stat* parameter to struct stat_beos*
  for sake of binary compatibility. This breaks source compatibility, though,
  which we can't help, since the class doesn't have reserved vtable slots.
* Fixed several issues with the stat structure change, mostly adjusted uses of

  as we need to call vm_page_allocate_page() with a cache locked.
* No longer use low_resource_state() to determine whether to precache or not,

* Also don't (try to) precache when the cache already has more than 2/3 of its
  pages to safe some unnecessary work.
* The size to precache was limited to the file size incorrectly.
* When precaching failed, the cache reference was not released.
* The precaching started one page too late, causing bug #3835.

* Implemented a way to do asynchronous pre-fetching when mapping files.
* There are slight code duplications in some places that could benefit
  from cleaning up, but nothing too bad.
* Implementing smarter ways to trigger prefetching and more analysis of
  the situations in the kernel would be nice. Currently up to 10 MB
  of every mapped file are pre-fetched without further analysis.
* The speed improvement is nice for certain operations. On our test
  system (real hardware), Firefox took 9 seconds from being launched
  to display a window. Now it takes 5 seconds. Both measurements
  right after booting. The same system took 35 seconds from launching
  Haiku in the GRUB menu to displaying the Tracker desktop background
  image. Now it takes 27 seconds.
* We didn't have the chance to check out the effects of this on the
  CD boot, but potentially, they could speed it up a lot.

227fe7d34a * Scheduler/wait object listener:
- Moved scheduler listening interface to <listeners.h> and added more
    convenient to use templatized notification functions.
  - Added a listener mechanism for the wait objects (semaphores, condition
    variables, mutex, rw_lock).
* system profiler:
  - Hopefully fixed locking issues related to notifying the profiler thread
    for good. We still had an inconsistent locking order, since the scheduler
    notification callbacks are invoked with the thread lock held and have to
    acquire the object lock then, while the other callbacks acquired the object
    lock first and as a side effect of ConditionVariable::NotifyOne() acquired
    the thread lock. Now we make sure the object lock is the innermost lock.
  - Track the number of dropped events due to a full buffer.
    _user_system_profiler_next_buffer() returns this count now.
  - When scheduling profiling events are requested also listen to wait objects
    and generate the respective profiling events. We send those events lazily
    and cache the infos to avoid resending an event for the same wait object.
  - When starting profiling we do now generate "thread scheduled" events for
    the already running threads.
  - _user_system_profiler_start(): Check whether the parameters pointer is a
    userland address at all.
  - The system_profiler_team_added event does now also contain the team's name.
* Added a sem_get_name_unsafe() returning a semaphore's name. It is "unsafe",
  since the caller has to ensure that the semaphore exists and continues to
  exist as long as the returned name is used.
* Adjusted the "profile" and "scheduling_recorder" according to the system
  profiling changes. The latter prints the number of dropped events, now.

146f113fec Fixed issues with the scheduling events. In the listener callbacks we
potentially want to notify the profiler thread (i.e. wake it up), which can
cause another scheduling event notification. That is we have to make sure that
event buffer is in a consistent state at that point (i.e. wake up the thread
at the very end of the callbacks). Furthermore the ThreadEnqueuedInRunQueue()
callback can be called with spinlocks besides the thread spinlock being held. In
particular waking up threads also happens in the condition variable code with
a static spinlock being held. Trying to notify the condition variable the
profiler thread is waiting on in such a case would be a guaranteed deadlock.
Hence we avoid doing that, now.

8b3b05cbf9 Synchronize the TSCs of all CPUs early in the boot process, so system_time()
will return consistent values. This helps with debug measurements for the time
being. Obviously we'll have to think of something different when we support
speed-stepping on models with frequency-dependent TSCs.

3539fc6e19 page writer:
* When writing a page failed it is not a good idea to re-enqueue it at the tail
  of the modified queue, since that is definitely behind the page writer's
  marker and the page would be picked up again before reaching the end of the
  queue. If that happened with more than 256 pages, the page writer would keep
  picking up only those non-writable pages and make no more progress.
* When selecting pages also skip temporary pages, if there's no more swap space
  available, since trying to write those pages would most likely fail anyway
  (triggering the first problem).

48b0c6f93a debug_trap_cpu_in_kdl(): If the CPU running the kernel debugger exited and
re-entered it fast enough, we wouldn't leave the loop and thus cause a
deadlock, since we wouldn't process the ICI message telling us to halt. We do
now call smp_intercpu_int_handler() in the loop and guard the function from
being re-entered. This also has the advantage that we can execute code on all
CPUs in the kernel debugger, if we have to.

  free it. Not removing the area mappings might have been the cause of #3110,
  not freeing it would cause it to be leaked for good.
* vm_page_write_modified_page_range(): When writing failed for another reason
  and the page wasn't in the modified queue before, we would lose the info
  in which queue it was before and setting the page state to modified would
  assume the active queue. This could potentially screw up our page queue
  structures.

  that all idle threads would always be ready or running. We now create the

14df3c2bed Various tweaks - 1) while enqueued, keep track of which run queue a thread is in on the scheduler data structure, and use this information so that set_thread_priority doesn't have to search every CPU to find the thread. Also slightly tweak the enqueue and steal operations to take advantage of some of the stats we're now tracking, and experiment with variable quantum sizes for low priority CPU bound threads. Still lots of work to do with respect to balancing and/or affinity though.

This allows to have the first item selected when entering a menu, since still
pressing space would not enter it unintentionally anymore, in case it's a sub-
menu again. Even though it makes some sense to have "Continue booting" selected
by default, it somehow feels more natural to have the first item always selected
instead. Thanks!
