01f964efeb Introduce a gSystemShutdown flag to be able to check if system is shutting down. ACPI Embedded Controller now uses polling when it is set to true.
This might help with ACPI shutdown issues, if not this change can be reverted. Not verified as it works on all my machines even without this.

3243de5750 boot_loader_openfirmware: Add iSCSI boot support
If no Haiku remote disk server is found, try an iSCSI discovery session on
the TFTP server, using the IP address from the boot command or OF options.
All available IPv4 targets are considered, Target Portal Groups are ignored.

RFC 4173 suggests a mechanism that avoids a discovery session by using DHCP;
that requires a compatibly configured DHCP server though and we wouldn't have
access to such data currently anyway. iSCSI is currently used as fallback,
and when it doesn't succeed it falls back to the menu as before.

Resolves ticket #5319.

5b086e27e8 boot_net: Add iSCSI initiator support
Add support for both discovery and regular iSCSI sessions. Command and status
sequence numbers do differentiate between session and connection but only
one connection per session is currently supported.

Code is Big Endian for now, so compile it for ppc only.

Based on RFC 3720 ff. Tested against OpenSolaris 2009.06.

eb5e456002 boot_net: Various TCP fixes
Don't enqueue a packet whose sequence number matches the first one in queue
or is between the next and the acknowledged on. This would lead to packet
duplication in the queue and leftovers after dequeuing.

Optimize calculation of acknowledgement number for out-of-order reception.
If a single missing packet arrived, this could have resulted in a timeout
depending on the window size.

In case the connection is closed, do dequeue remaining packets. This would
have caused a read error after a unidirectional FIN.

Prepare a dynamic window size calculation.

Do checksum calculation before attempting to trace packet contents. I have
seen a few and couldn't spot an error in the checksum calculation.

More fine-grained control over trace output.
Trace the Maximum Segment Size option if present; break after End of Options.

b7e825d6e7 boot_net: Add TCP support
Modelled after UDP, add limited TCP support to the boot net stack. The socket
works by queuing received packets as well as sent packets that have not yet
been ACK'ed. Some known issues are documented, especially there's only limited
congestion control. I.e., we send immediately and in unlimited quantity, thus
its use should be restricted to local networks, and due to a fixed window size
there is potential for our socket being overrun with data packets before they
are read. Some corner cases like wrapping sequence numbers may cause a timeout.

The TCP implementation is based on Andrew S. Tanenbaum's "Computer Networks",
4th ed., as well as lecture notes from Prof. W. Effelsberg, the relevant RFCs
and Wikipedia. The pseudo-random number Galois LFSR used for the sequence
number was suggested by Endre Varga.

Since the code is unlikely to get much smaller, better merge it now so that
subsequent changes get easier to review. No platform actively uses TCP sockets
yet, and the receiving code has been reviewed for endianness issues and should
terminate okay after verifying the checksum if no sockets are open.
Based on a version tested with custom code (#5240) as well as with iSCSI.
Compile-tested boot_loader_openfirmware, pxehaiku-loader with gcc4 and
haiku_loader with gcc2. Closes ticket #5240.

Changes from #5240 proposed patch:
* Various bug fixes related to queuing, some memory leaks fixed.
* Never bump the sequence number when dequeuing a packet. It's done afterwards.
* Don't bump the sequence number again when resending the queue or ACK'ing.
* Aggressively ACK while waiting for packets.
* Don't queue sent ACK-only packets.
* More trace output, esp. for queue inspection.
* Adapted use of TCP header flags to r38434.

56f837e265 boot_loader_openfirmware: Fix system_time()
system_time() was based on of_milliseconds(), which returns the number of
milliseconds since power-on. This would produce very similar or identical
results for subsequent boots due to limited clock resolution; therefore it
was unsuited as PRNG seed, e.g., for TCP ports.

Try to inquire the RTC device node with get-time to return an improved time
value, if possible.

Closes ticket #6061.

Changes from proposed patch:
* Obtain the RTC handle once and reuse it for each inquiry.

platform_boot_options() has the BOOT_OPTION_DEBUG_OUTPUT flag set.

If the space bar is pressed, enter the boot menu. If the escape key is pressed,
disable the frame buffer and keep showing the usual debug output. Apparently
the key press must come after console/keyboard initialization but before the
"Welcome to the Haiku bootloader!" line.

4d95518e60 boot_loader_openfirmware: Avoid console interference with frame buffer
Debug output calls OpenFirmware methods writing text into the frame buffer.
Depending on the screen mode this leads to garbled display or parts of the
screen overwritten, so mute the output during frame buffer use for now.

A better solution would be to redirect the output elsewhere (e.g., #6168),
so that ConsoleHandle::WriteAt() is not called for the problematic handle
in the first place. That does not work inside the kernel yet.

31bce16715 ppc: Keep memory mappings set up by OpenFirmware
Revert r36886 and fix compilation of insert_virtual_range_to_keep().
The use of void* vs. addr_t matches the surrounding boot loader code
but should probably be revised in favour of addr_t.

create_area() in the kernel wrongly assumed a RAM-backed address range,
which was destined to fail since ranges below the kernel address space
were ignored anyway. Use vm_map_physical_memory() instead.

This fixes a hang once the frame buffer and other resources used by OF
get unmapped. Closes ticket #5193 again.

3426ce1404 * Thanks to Janito I had a closer look to cache_detach_sub_transaction(), and it
turned out it's pretty much broken. Not only did it potentially leak memory,
  it would also potentially replace the original data with a NULL pointer,
  making the current transaction non revertable. The code should now be much
  clearer. This fixes bug #6378.
* Changed a few "if (... != NULL)" into ASSERTs, since the code should bail out
  earlier in these cases already.
* Added a TODO comment to cache_start_sub_transaction() about its broken discard
  handling. This can cause FS corruptions in case the parent transaction is ever
  going to be aborted (which shouldn't happen in real life, though).
* Added a bit more and better comments.

7e965f506d More consolidation of timezone code:
* dropped DaylightSavingTime from real_time_clock code in kernel, it was
  never really being used for what it meant (and just being referred to by
  gettimeofday(), which put a different meaning to it
* adjusted the syscalls get_timezone() & set_timezone() as well as their callers 
  accordingly
* got rid of get_rtc_info() and rtc_info struct in kernel, as it was only
  being referred to by the FAT add-on and that one (like gettimeofday()) put a
  different meaning to tz_minuteswest. Added a comment to FAT's util.c
  showing a possible solution, should the hardcoded GMT timezone pose a problem.
* fixed declaration of gettimeofday() to match POSIX base specs, issue 7
* changed implementation of gettimeofday() to not bother trying to fill struct
  timezone - it was using wrong values before, anyway.

  relevant (and the two corresponding parameters were removed)
* C++-ified and reworked clockconfig to use the info from 'Time settings'

* removed invocation of _kern_get_tzfilename() from tzset(), as the syscall
  no longer exists and tzset() is currently broken anyway
* adjusted the Time preflet to use the renamed syscall when getting/setting 
  the RTC info

61729d9323 * Reworked the complete stack to allow more than one address per network
interface - this caused quite a number of changes.
* Network interfaces, and its addresses are now reference counted (not yet
  complete, though, InterfaceAddresses need to hold references to their
  interface as well).
* There are two known regressions of this commit that I will fix later:
  - you cannot remove interfaces anymore
  - IPv4 multicast was broken anyway, but now it's disabled, too.
* Moved a device_interfaces.cpp|h out of interfaces.cpp.
* The datalink layer chain is now instantiated per domain per interface,
  not just per interface anymore.
* When a buffer reaches the network layer, it has no known interface yet, ie.
  the ipv4|6|whatever modules need to set this manually.
* Added more debug output, and some new debugger commands, the control option
  is now printed in clear text.
* Added hash_address() function to the address modules. Added "const" to
  set_to_defaults() where needed.
* Fixed net_buffer's restore header functions offset use as reported by Atis.
* Improved buffer dump output, use the domain module to print the address if
  available.
* Moved net_buffer::type into the union, as it's not needed by the upper layers
  anymore.
* Moved IPv6 specific code from {add|remove}_default_route() to where it
  belongs, but disabled it for the time being.
* Completely discarded useless ipv4_datagram module.
* Added ping6 to the build.

    time. This mitigates the busyness the page writer falls into when there
    are enough modified pages to make it run all the time but none that can be

3aea1d4f53 * Added ObjectCache::alignment, the object alignment and used the alignment for
incrementing the cache color cycle. Using the fixed value (8) would
  potentially misalign the object again.
* Don't use CACHE_ALIGN_ON_SIZE for object caches any longer -- we have the
  alignment parameter anyway (the flag is still used for the MemoryManager,
  though).
* ObjectCache::InitSlab(): Slab coloring *was* done when CACHE_ALIGN_ON_SIZE
  was given, i.e. exactly the wrong way around. Also the cache_color_cycle
  computation was weird -- color 0 was used twice in a row.
* The "slabs" and "slab_cache" KDL commands also print the alignment, now.

  recently used heap allocator apparently aligned the structures to 16 byte
  anyway and the now used slab allocator has a bug preventing slab coloring
  for that object size.

b944766870 * Moved the vm_page initialization from vm_page.cpp:vm_page_init() to the new
vm_page::Init().
* Made vm_page::wired_count private and added accessor methods.
* Added VMCache::fWiredPagesCount (the number of wired pages the cache
  contains) and accessor methods.
* Made more use of vm_page::IsMapped().
* vm_copy_on_write_area(): Added vm_page_reservation* parameter that can be
  used to request a special handling for wired pages. If given the wired pages
  are replaced by copies and the original pages are moved to the upper cache.
* vm_copy_area():
  - We don't need to do any wired ranges handling, if the source area is a
    B_SHARED_AREA, since we don't touch the area's mappings in this case.
  - We no longer wait for wired ranges of the concerned areas to disappear.
    Instead we use the new vm_copy_on_write_area() feature and just let it
    copy the wired pages. This fixes #6288, an issue introduced with the use
    of user mutexes in libroot: When executing multiple concurrent fork()s all
    but the first one would wait on the fork mutex, which (being a user mutex)
    would wire a page that the vm_copy_area() of the first fork() would wait
    for.

b62981b983 OpenFirmware: Make of_milliseconds() return error
The only user of of_milliseconds(), the boot loader's system_time(),
checks for an error that would never be signalled since the zero-initialized
number of milliseconds would always be returned.

Return OF_FAILED instead to allow explicit error handling in that case.

While this is a behavioral change, it is not yet a functional change,
for system_time()'s implementation translates OF_FAILED back to zero currently.

fa04c15cde object_cache_low_memory(): Reduce the cache pressure indicator even for the

Fixes #5816.

* block_cache::Allocate(): No longer removes unused blocks when in a low

  cache was actively used for writing, seriously affecting performance.
* block_cache::_LowMemoryHandler(): Compute the number of unused blocks to
  remove depending on the total unused block number. This way we cull huge
  block caches with lots of old blocks much quicker.

Treats part of #5816.

9623c48284 SMP: remove the tracking of apic id -> cpu id. Don't pass between bootloader and kernel.
Kernel doesn't use it, and it could be regenerated in the kernel if it did need it.

This also unlocks the apic range the bios can use. Previously the apic ids would have
to fit within 0..MAX_CPUS or it'd reject the cpu. Some boxes (mine in particular)
seem to sparsely populate the apic id so that the range is pretty large.

977ffe5233 No longer ignore the physical memory beyond 4 GB, if we have a 64 bit
phys_addr_t. IOW, if PAE is enabled, that memory should be put to use now.
Apparently we report an incorrect amount of total memory (also counting
memory gaps), which also suggests that we need another method to manage the
vm_page structures (currently a huge array with indexes proportional to
physical page addresses, i.e. wasting memory for the gaps).

2434bdc4d9 * Introduced global variable gX86PagingMethod, so the paging method can be
accessed from anywhere. Added static X86PagingMethod32Bit::Method()
  returning it as the subtype pointer -- to be used in the code related to
  that method only, of course.
* Made a bunch of static variables non-static members of
  X86PagingMethod32Bit and added accessors for them. This makes them
  accessible in other source files (allowing for more refactoring) and saves
  memory, when we actually have another paging method implementation.

  ie. each B_GET_GEOMETRY/B_GET_DEVICE_SIZE will trigger it), and there is no

  code.

  phys_{addr,size}_t remain 32 bit wide -- keeps binary compatibility with

* Adjusted all code using the affected interfaces (Oh what fun!). Added a few
  TODOs in places where the wrong types (e.g. void* for physical addresses
  are used). Looks like quite a few drivers aren't 64 bit safe and others
  will break with PAE.

53d7472637 BOOT SMP: allow systems with a large number of cpus and/or sparse apic ids to actually boot
The old mechanism to route an apic id back to a cpu id is faulty, built with the assumption that
the bios will 'pack' the apic ids from 0-num_cpus. In systems that dont do that, the code would
randomly corrupt the bootloader. Fatal in this case.

This quick fix simply rejects all apic ids >= MAX_CPUS (8). No way it would have worked before
if you had a box that started with >= 8 or anything, so it shouldn't regress any existing system.

Better solution is to allow any apic id to exist (0-255).

On this particular box the ids (from lunix dmesg):
SRAT: PXM 0 -> APIC 0 -> Node 0
SRAT: PXM 1 -> APIC 16 -> Node 1
SRAT: PXM 0 -> APIC 2 -> Node 0

13fa4c845a * Introduced new area creation flag CREATE_AREA_DONT_COMMIT_MEMORY.
map_backing_store() doesn't commit memory when this flag is given.
* Used the new flag vm_copy_area(): We no longer commit memory for read-only
  areas. This prevents read-only mapped files from suddenly requiring memory
  after fork(). Might improve the situation on machines with very little RAM
  a bit.
  We should probably mark writable copies over-committing, since the usual
  case is fork() + exec() where the child normally doesn't need more than a
  few pages until calling exec(). That would significantly reduce the memory
  requirement for jamming the Haiku tree.

fa0c1e96a0 Hopefully the last work on the MTRR code for the time being:
Since we also force uncacheability via the PTEs, it is no longer necessary to
use MTRRs for uncacheable ranges. It is recommended, which is why we still do
it, if possible, but when we run out of MTRRs, the algorithm ignores
uncacheable ranges now -- iteratively it increases the minimum size of ranges
to drop until the available MTRRs suffice.
Should fix #5703 and #5865.

26f1dd2708 Added a third rendez-vous point for the call_all_cpus() MTRR functions. This
fixes the problem that the CPU initiating the call could make the next call
and reset sCpuRendezvous2 before the other CPUs have returned from their
smp_cpu_rendezvous(). Probably virtually impossible on real hardware, but I
could almost reliably reproduce it with qemu -smp 2 (would hang the late boot
process without ability to enter KDL).

7f987e49d7 Added a rendez-vous variable parameter to smp_trap_non_boot_cpus() and make
boot CPU wait until all other CPUs are ready to wait. This solves a
theoretical problem in main(): The boot CPU could run fully through the early
initialization and reset sCpuRendezvous2 before the other CPUs left
smp_cpu_rendezvous(). It's very unlikely on real hardware that the non-boot
CPUs are so much slower, but it might be a concern in emulation.

d62afe7ab0 VMUserAddressSpace::LookupArea(): Although only a read-lock is the
precondition for calling the function it read/write accessed the fAreaHint
attribute in a non-atomic manner. I.e. if executed concurrently by two
threads of the same team one could return the wrong area. The most likely
problem could be caused in vm_soft_fault(), leading to pages being added to
the wrong caches.
The bug itself is inherited from NewOS, but is triggered way more likely
since the page daemon unmaps inactive pages (r35485). Probably fixes #5413.
Might also fix the sporadically occurring crashes/asserts in the hoard
allocator -- at least inactive pages being replaced by zeroed ones would be
an excellent explanation.

b1e06d23ce * The "page_stats" command does now also print the longest contiguous runs of
free respective free and cached pages.
* Removed the unused vm_page_allocate_page_run_no_base().
* vm_page_allocate_page_run() (and allocate_page_run()):
  - Use vm_page_reserve_pages() instead of vm_page_try_reserve_pages(), i.e.
    wait until the reservation succeeds.
  - Now we iterates two times through the pages to find a suitable page run. In
    the first iteration it only looks for free/clear pages, in the second
    iteration it also considers cached pages. This increases the chance of the
    function to succeed, when a lot of caching is going on.
    This reduces the amount of memory required to use the IOCache when booting
    off the anyboot Live CD to around 160 MB in qemu. It also seems to work with
    128 MB, but the syslog indicates that some memory allocations fail, which
    is not exactly inspiring confidence.

f14480bc2c Essentially rewrote the IOCache to use a VMCache and unmapped pages for
caching (similar to the file cache) instead of contiguous areas. This is
probably a little bit slower, but integrates better with the VM -- the
caching doesn't increase memory pressure and the least recently used pages
will automatically be recycled when needed.
There are still memory allocation issues on machines with little memory. The
USB stack apparently tries to allocate a rather big chunk of contiguous
memory, which fails when all not otherwise bound memory is used for caches,
since the VM functions for allocating contiguous memory consider only free
pages ATM.

  inconsistently by the derived classes. Now it returns whether the backing
  store can provide the page (via Read()). The default implementation returns
  false. VNodeCache::HasPage() only returns true, if the given offset is
  within the cache (i.e. file) bounds. This prevents vm_soft_fault() from
  adding clean pages to vnode caches on faults beyond the file bounds.
  Probably fixes #5473 -- at least mmap_resize_test behaves correctly, now.
* Removed redundant HasPage() and Fault() overrides in VMCache derived
  classes.

f71274580b * Private libroot locking primitives:
- Reimplemented mutex to use the _kern_mutex*() syscalls.
  - The initializer functions cannot fail anymore -- changed their return type
    to void.
  - Changed the initializer function semantics to not copy the name by default
    anymore (as in the kernel). Also added *_etc() versions of them that take an
    additional flags.
  - Added static initializer macros.
  - Made the mutex (and thus recursive_lock) lock functions non-interruptable.
  - Got rid of the "lazy" version. They are no longer needed, since the
    initialization of the standard types can be done statically and cannot fail.
* Adjusted libroot, runtime loader, and other code using the private libroot
  locking primitives to the new semantics.
* pthreads mutexes and condition variables:
  - Reimplemented using the _kern_mutex*() syscalls.
  - Consistently use POSIX error codes.
  - Fixed some not quite POSIX compliant behavior.

fba2ee2527 * We should check for the I/O APIC before mapping it (since we panic if mapping
it failed...).
* Moved IRQ table reading much earlier (before starting to program the I/O
  APIC), though it currently fails, possibly because the device manager isn't
  up yet, and there is no embedded controller driver.
* The kernel now enables I/O APICs by default, but the boot loader disables
  them - you can now enable them using the safe mode menu, but it currently
  won't have any (positive) effect.

The O_CLOEXEC open mode wasn't actually set in the close-on-exec bitmap causing
all files opened with O_CLOEXEC (like done in the storage kit classes) to still
be inherited. This caused for example to be unable to unmount volumes when
opening apps while Tracker touched some files (i.e. copying some large files)
since these apps would inherit the file descriptor and therefore keep the
volume busy.

50e4dd9328 axeld + bonefish: X86VMTranslationMap::Protect():
* Removed rounding up the end address to page alignment. It's not necessary
  and could cause an overflow.
* Fixed possible infinite loop triggered by a rare race condition: When two
  threads of a team were accessing the same unmapped page at the same time
  each would trigger a page fault. One thread would map the page again, the
  second would wait until the first one was done and update the page
  protection (unnecessarily but harmlessly). If the first thread accessed the
  page again at an unfortunate time, it would implicitly change the
  accessed/dirty flags of the page's PTE, which was a situation the loop in
  Protect() didn't consider and thus run forever.
  Seen the problem twice today in form of an app server freeze.

  (it consists only of setting the mutex value to 0). An uncontended lock or
  unlock operation can basically consist of an atomic_*() in userland. The
  syscalls (when the mutex is contended) are a bit more expensive than semaphore
  operations, though.

5a0b30dbda Don't cancel the alarm on exec*(). POSIX alarm() requires that. The BeBook
doesn't mention the expected set_alarm() behavior. Tests under BeOS R5 Bone
crash the system in either case, though, so I guess we're free to go with the
expected POSIX behavior.
This make detection of hanging tests in the Open POSIX Test Suite work.

4f774c503c * VMArea::Unwire(addr_t, size_t, bool): Don't delete the removed range, but
return it.
* lock_memory_etc(): On error the VMAreaWiredRange object could be leaked.
* [un]lock_memory_etc(): Call VMArea::Unwire() with the cache locked and
  explicitly delete the range object after unlocking the cache to avoid
  potential deadlocks.

369111e741 * Removed the VMArea::Wire() version that has to allocate a VMAreaWiredRange.
Since the requirement is that the area's top cache is locked, allocating
  memory isn't allowed.
* lock_memory_etc(): Create the VMAreaWiredRange object explicitly before
  locking the area's top cache.

Fixes #5680 (deadlocks when using the slab as malloc() backend).

550376ffb8 * vm_delete_areas(): Changed return type to void (was status_t and not used).
* _user_map_file(), _user_unmap_memory(): Verify that the address (if given) is
  page aligned.
* Reworked memory locking (wiring):
  - VMArea does now have a list of wired memory ranges and supports waiting for
    a range to be removed.
  - vm_soft_fault():
    - Added "wirePage" parameter that, if given, makes the function wire the
      page and return it.
    - Added "wiredRange" parameter (for calls from lock_memory_etc()) and made
      sure we never unmap wired pages. This could e.g. happen when a page from a
      lower cache was read-mapped and a write fault occurred. Now in such a
      situation the function waits for the page to be unwired and restarts.
  - All functions that manipulate areas in a way that could affect wired ranges
    do now either require the caller to make sure there are no wired ranges in
    the way or do that themselves. Added a few wait_if_*_is_wired() helper
    functions for that purpose.
  - lock_memory_etc():
    - Does now also work correctly when the range spans more than one area.
    - Adds VMAreaWiredRanges to the affected VMAreas and retains an address
      space reference (so that the address space won't be deleted as long as a
      wired range exists).
    - Resolved TODO: The area's caches are now locked when
      increment_page_wired_count() is called.
    - Resolved TODO: The race condition due to missing locking after looking up
      the page mapping is now prevented. We hold the cache locks (in case the
      page is already mapped) and the new vm_soft_fault() parameter allows us
      to get the page wired.
  - unlock_memory_etc(): Changes symmetrical to those in lock_memory_etc() and
    resolved all TODOs.

feddedab0c x86:
Added fields for temporary storage of the debug registers dr6 and dr7 to the
arch_cpu_info structure. The actual registers are stored at the beginning of
x86_exit_user_debug_at_kernel_entry() and read in
x86_handle_debug_exception().
The problem was that x86_exit_user_debug_at_kernel_entry() itself overwrote
dr7 and, if kernel breakpoints were enabled, dr6 could be overwritten anytime
after. So x86_handle_debug_exception() would find incorrect values in the
registers (definitely in dr7) and thus interpret the detected debug condition
incorrectly. Usually watchpoints were recognized as breakpoints.

64c15cfc27 * sCurrentKernelDebuggerMessageArgs is no longer used directly. Whenever it
is passed to some v*printf(), we clone it first. This way we can use it
  repeatedly. It worked only on certain architectures correctly before.
* Changed the panic() semantics a bit: When the format contains the
  (hopefully unusual enough) string "@!" only the part before it is
  considered to belong to the panic message. The part after it is interpreted
  as a command line to be executed directly after entering KDL. This way it
  is possible to provide helpful command invocations only developers somewhat
  familiar with the subsystem might come up with. E.g.:
    panic("dec_vnode_ref_count: called on busy vnode %p"
      "@! vnode -p %p; mount _mount", vnode, vnode);

28a2172c3f kernel:
* The kernel syslog ring buffer is no longer emptied by the syslog sender
  thread. Instead we only drop the oldest data from the buffer when we're
  writing to it and there's not enough free space in it.
  Advantages: We drop old data rather than the most recent data when the buffer
  is full. The "syslog" KDL command has more data available now. So the odds
  are that kernel syslog messages not written to disk yet are at least still
  in the kernel buffer.
* Changed dprintf_no_syslog() semantics: Now it writes to the syslog, but
  doesn't notify the syslog sender thread.

boot loader:
* Added the ring_buffer implementation and a dummy user_memcpy().
* bios_x86: Moved the syslog stuff from serial.{cpp,h} to debug.{cpp.h}.
* Moved the debug options from the "Select safe mode options" menu to a new
  "Select debug options" menu.
* Added option "Enable debug syslog" to the new menu (ATM available on x86
  only). It allocates a 1 MB in-memory buffer for the syslog for this session
  in such a way that it can be accessed by the boot loader after a reset.
* Added item "Display syslog from previous session" to the new menu, doing
  what its name suggests.

from inserting a clean page, if a fault happens. VMNullCaches are used by the
slab's memory manager -- all page faults in slab areas are serious bugs and
we want to panic() immediately.

0181fe4b21 * Replaced cached_block::accessed (the number of accesses) with last_accessed
(the time of the last access), as what we really want is a frequency/last
  access time scoring, and accessed alone is useless for that.
* put_cached_block() no longer frees any unused blocks.
* The low memory handler will now only lock the cache if there is something
  to do. Also, it did not take address space warnings into account.
* Even when memory is critical, we don't free all unused blocks anymore - if
  the number of blocks we free now (10000) is not sufficient to get out of the
  critical condition, chances are good that we will be called again :-)
* block_notifier_and_writer() now tries to make sure that the total block cache
  memory consumption grows not much larger than half of the available RAM.
* This should all help to limit the block cache usage a bit better. Hopefully,
  a checkfs run will no longer run out of memory here (couldn't test yet).

d40a935560 Boot loader (x86 mmu.cpp):
* Made the page table allocation more flexible. Got rid of sMaxVirtualAddress
  and added new virtual_end address to the architecture specific kernel args.
* Increased the virtual space we reserve for the kernel to 16 MB. That
  should suffice for quite a while. The previous 2 MB were too tight when
  building the kernel with debug info.
* mmu_init(): The way we were translating the BIOS' extended memory map to
  our physical ranges arrays was broken. Small gaps between usable memory
  ranges would be ignored and instead marked allocated. This worked fine for
  the boot loader and during the early kernel initialization, but after the
  VM has been fully set up it frees all physical ranges that have not been
  claimed otherwise. So those ranges could be entered into the free pages
  list and would be used later. This could possibly cause all kinds of weird
  problems, probably including ACPI issues. Now we add only the actually
  usable ranges to our list.

Kernel:
* vm_page_init(): The pages of the ranges between the usable physical memory
  ranges are now marked PAGE_STATE_UNUSED, the allocated ranges
  PAGE_STATE_WIRED.
* unmap_and_free_physical_pages(): Don't free pages marked as unused.

1c164de7d2 * Quick&dirty fix of a race condition that caused an endless loop in
object_cache_alloc(): the ObjectCache::total_objects count was increased in
  ObjectCache::InitSlab(), but the slab was really only added at a later point
  between the cache could be unlocked.
* If a second object_cache_reserve_internal() managed to be called while the
  lock was unlocked, it would see that there has to be space available, and
  will then return -- however, since the other thread could not yet place the
  slab into the cache, object_cache_alloc() cannot find it.

36eb70516c Fixed various problems which didn't let HPET timers work on my machine, most
notably:
- in hpet_clear_hardware_timer() we cleared the HPET_CONF_TIMER_INT_ENABLE
flag, and never set it back anymore (now we do, in hpet_set_hardware_timer())
- the incorrect interrupt configuration (although it shouldn't matter in legacy mode).
Also test the HPET counter before trying to use it.
Improved debug information.
HPET timers are still at priority 0, since I coulnd't yet test on other
machines (besides mine, QEMU and XenServer 5.5), and doen't work for
some reason with SMP enabled.

  (cf. #3487). We still don't handle the resulting debug exception correctly,

ff59ce680d * The low resource handler now empties the cache depot's magazines; before,
they were never freed unless the cache was destroyed (I just wondered why
  my system would bury >1G in the magazines).
* Made the magazine capacity variable per cache, ie. for larger objects, it's
  not a good idea to have 64*CPU buffers lying around in the worst case.
* Furthermore, the create_object_cache_etc()/object_depot_init() now have
  arguments for the magazine capacity as well as the maximum number of full
  unused magazines.
* By default, you might want to initialize both to zero, as then some hopefully
  usable defaults are computed. Otherwise (the only current example is the
  vm_page_mapping cache) you can just put in the values you'd want there.
  The page mapping cache uses larger values, as its objects are usually
  allocated and deleted in larger chunks.
* Beware, though, I couldn't test these changes yet as Qemu didn't like to run
  today. I'll test these changes on another machine now.

dac21d8bfe * map_physical_memory() does now always set a memory type. If none is given (it
needs to be or'ed to the address specification), "uncached" is assumed.
* Set the memory type for the "BIOS" and "DMA" areas to write-back. Not sure, if
  that's correct, but that's what was effectively used on my machines before.
* Changed x86_set_mtrrs() and the CPU module hook to also set the default memory
  type.
* Rewrote the MTRR computation once more:
  - Now we know all used memory ranges, so we are free to extend used ranges
    into unused ones in order to simplify them for MTRR setup.
  - Leverage the subtractive properties of uncached and write-through ranges to
    simplify ranges of any other respectively write-back type.
  - Set the default memory type to write-back, so we don't need MTRRs for the
    RAM ranges.
  - If a new range intersects with an existing one, we no longer just fail.
    Instead we use the strictest requirements implied by the ranges. This fixes
    #5383.

Overall the new algorithm should be sufficient with far less MTRRs than before
(on my desktop machine 4 are used at maximum, while 8 didn't quite suffice
before). A drawback of the current implementation is that it doesn't deal with
the case of running out of MTRRs at all, which might result in some ranges
having weaker caching/memory ordering properties than requested.

c5e52ecb78 * cache_sync_transaction() now puts all blocks into the BlockWriter, and
therefore does not unlock anymore while iterating over the transactions.
  This gave other threads the opportunity to finish a transaction, causing
  bug #5412. Also, the BlockWriter will now always close transactions on its
  own, and you need to pass the transaction hash iterator to Add().
* Also, transactions that contain blocks that are currently written back will
  be ignored by the block writer, as well as cache_sync_transaction(). This
  fixes bug #5415.
* Improved error handling if BlockWriter fails to write back blocks. Most
  notably, they are no longer left busy_writing, and the functions calling
  it do proper error reporting (besides block_cache_discard() that does not
  return any erro code; I've added a TODO note there for now).
* The BlockWriter now starts with a larger array once it has to allocate one.
* One can now limit the number of blocks that go into a BlockWriter. This is
  used by the block writer thread, that shouldn't always write back everything
  every two seconds.
* Also, the fixed array is larger now (leaving enough space such that the
  block writer/notifier does not need to allocate anything).
* And finally, if allocating the array fails, the BlockWriter falls back to the
  synchronous write back used previously. IOW it will never write back less
  blocks than you ask for.
* Added static BlockWriter::WriteBlock() method replacing write_cached_block().
* Forgot to rename block_cache::busy_count to busy_reading_count.

1f611c018b The file cache code was completely ignoring the vm_page::modified flag. In
particular it wouldn't set the flag when writing something to a page, but
only move it to the modified queue. Since mapping the page would move it to
another queue, the information that the page was modified would be lost and
it would never be written to disk. Was well reproducible with a Haiku image
build and limited amount of memory.
Fixes the hopefully last remaining cause for #5374.

6949076049 * Added some more asserts for cached pages.
* full_scan_inactive_pages(): Fixed syntactical glitch (missing "else").
  Affected only the active paging mode and was relatively harmless. The worst
  case would be that an inactive page would be moved to the cached queue
  although its usage_count hadn't dropped to 0 yet, thus freeing it before
  pages that deserved it more.
* move_page_to_active_or_inactive_queue():
  - Was ignoring the page's modified flag, thus potentially moving a modified
    page to the cached queue. That could happen only in rare cases though,
    like when the page was still mmap()ped while being written and modified and
    unmapped before being done.
  - No longer move the page to the inactive queue, even if its usage count is 0.
    In idle mode the page daemon doesn't look at inactive pages, so the page's
    stats wouldn't be updated anymore.
  - Renamed to move_page_to_appropriate_queue().

fa47a7c434 page_writer():
* Use the same criterion when to write back temporary pages as the page daemon.
* Move wired and temporary pages that shall not be written back to the active or
  inactive queue so they don't get stuck in the modified queue and potentially
  cause the page writer to run permanently without actually making progress
  (#5382).

page writing implementation:
* If writing back a temporary page failed, move it back to the inactive or
  active queue, so it doesn't get stuck in the modified queue. If active paging
  continues, it might find its way back to the modified queue in the next
  iteration, but that improves the situation a bit at least. Particularly with
  the port heap pages not really being swappable ATM.
* Never dequeue pages from the modified queue. We mark them busy, so the page
  writer will skip them anyway. This allows others to play with the page to some
  extend (at least allowing to move it between the queues). This fixes #5404.
* Removed PageWriteWrapper::ClearModifiedFlag(). We clear the modified flag in
  PageWriteWrapper::SetTo(), now, so that the page writer doesn't need to do
  that explicitly either.

081ff2db28 * Add heap_debug_set_memory_reuse() which allows to disable memory reuse,
keeping all returned heap memory in the 0xdeadbeef state (including the
  first sizeof(void *) bytes otherwise for the free list). While wasting a lot
  of memory it allows you to rely on 0xdeadbeef being always present as no
  future allocation will reuse the freed memory block.
* Also added heap_debug_malloc_with_guard_page() which is intended to allocate
  a memory block so it is aligned that the start of invalid memory past the
  allocation is in an unmapped guard page. However the kernel backend that would
  guarantee this is not yet implemented, so right now this works only by chance
  if no other area happens to be allocated exactly past the created one. With a
  very specifc suspicion you can put that one allocation you get to good use
  though. It causes a crash when accessing memory past the allocation size so
  you actually get a backtrace from where the access happened instead of only
  after freeing/wall checking.

638a24fa52 * Seperate the raw page wise allocation and allocations from bins.
* Make the contiguous page allocation capable of aligning the allocation
  and make it more clever by checking up front if there's a chance of getting
  enough pages at all, by giving up earlier if the page count can't be fit
  anymore, and in the alignment case by only checking the pages which have a
  valid alignment.
* If the alignment requirement is > B_PAGE_SIZE we now use page allocation
  directly, because the bins aren't necesarily aligned on their size past
  B_PAGE_SIZE anymore.
* When doing aligned bin allocation, calculate the aligned size up front and
  choose the right heap for the allocation.
* Also when doing aligned bin allocations we not only need to round up the size
  but also ensure that the bin we choose is aligned at all.
* Moved adding leak check info into it's own function.

or when using alignments < allocation size. Also the directly aligned page
allocations now only use up as many pages as actually required instead of
allocating based on the rounded up to align size.

4dafcc3b3b Since we potentially split segments into different regions, we need to
consider that when filling in the text and data ranges of the image info.
This fixes #5361 and #5351, caused by libtracker.so not finding its own
image.
