7435db9ff0 * _user_read_dir(): Allocate a temporary heap buffer passed into the kernel
instead of using the user buffer. This frees the VFS and FS implementations
  from handling user buffers.
* Adjusted fix_dirent() accordingly.

Start of framebuffer initialization for the Verdex board.
For now it points to the data section as framebuffer for testing and shows an RGB pattern.

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?

- don't clobber the parameter regs in the entry point,
- fix entry point address for netbsd loader emulation,
- added a gUImage global to point to the uimage blob with the tgz,
- added tgz info to platform stage2 args,
- add simple uimage support, just dumps the header and gets the nth blob in the image, (seems we have a bug in the math code, some infos don't print),
- 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

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

  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

  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
  partition map child creation.
* 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
  one).

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.

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 :-)
