fb2500da15 * Added missing AT_EACCESS.
* Implemented renameat(), faccessat(), fchownat(), fchmodat(), and mkfifoat().
* Added stub for mknodat().
* The kernel backend for faccessat() does not yet differentiate between
  effective and real user/group IDs, though.
* Removed B_ENABLE_INCOMPLETE_POSIX_AT_SUPPORT, as we now support everything
  (more or less). This also closes ticket #4928.

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.

d6778355ee * <DiskDeviceTypes.h>: Removed kPartitionTypeIntel{Primary,Logical} constants.
* Added new header headers/private/system/disk_device_types.h, which defines
  the <DiskDeviceTypes.h> constants as macros and which can be used where the
  constants cannot be used. The constants are defined using the macros, so now
  there's only one place where the string literals should be specified.
* Use the macros in the partitioning systems. I was too lazy to also adjust the
  file systems -- most of them seem to hard-code the string literal yet.

8ae594ffd4 * Introduced dedicated syscalls for the deprecated BeOS fs_attr API. Before,
each attribute access needed 3 syscalls, now only one as it should.
* Renamed the new Haiku call fs_open_attr() to fs_fopen_attr(), and added a new
  function fs_open_attr() that takes a path (same semantics as the
  fs_[f]open_attr_dir() functions already present in BeOS).
* Merged former _kern_open_attr(), and _kern_create_attr() into one syscall.
* Cleaned up vfs.h.

f75b8de3fc * Discarded the "parametersSize" parameter from various disk device manager
functions.
* Since we now use UserStringParameter, this fixes the missing null termination
  of the parameter string, and thus bug #4045.

* Adjusted syscalls accordingly.

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().

  to make sure there is enough space left for all areas of a single image.

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.

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.

5b2f0f33f9 * Changed the interface of _kern_system_profiler_start(). The parameters are
passed in a structure now, so it is easier to extend it and ignore unused
  parameters.
* One can now select which system profiling events one is interested in.
* Added scheduling events to the system profiling interface. Those are pretty
  much the ones recorded when scheduler tracing is enabled. Still missing are
  the "wait object" events that allow to interpret what a thread is waiting
  for.

1b9d2885d3 * Also pass the team arguments and thread names with the respective system

* profile: Avoid using get_{team,thread}_info() in common code paths. The
  system profiling mode is asynchronous, so the team or thread in question
  could already be gone.

47c40a10a1 * Prefixed memset_physical() and memcpy_to_physical() with "vm_",
added vm_memcpy_from_physical() and vm_memcpy_physical_page(), and
  added respective functions to the vm_translation_map operations. The
  architecture specific implementation can now decide how to implement
  them most efficiently. Added generic implementations that can be used,
  though.
* Changed vm_{get,put}_physical_page(). The former no longer accepts
  flags (the only flag PHYSICAL_PAGE_DONT_WAIT wasn't needed anymore).
  Instead it returns an implementation-specific handle that has to be
  passed to the latter. Added vm_{get,put}_physical_page_current_cpu()
  and *_debug() variants, that work only for the current CPU,
  respectively when in the kernel debugger. Also adjusted the
  vm_translation_map operations accordingly.
* Made consequent use of the physical memory operations in the source
  tree.
* Also adjusted the m68k and ppc implementations with respect to the
  vm_translation_map operation changes, but they are probably broken,
  nevertheless.
* For x86 the generic physical page mapper isn't used anymore. It is
  suboptimal in any case. For systems with small memory it is too much
  overhead, since one can just map the complete physical memory (that's
  not done yet, though). For systems with large memory it counteracts
  the VM strategy to reuse the least recently used pages. Since those
  pages will most likely not be mapped by the page mapper anymore, it
  will keep remapping chunks. This was also the reason why building
  Haiku in Haiku was significantly faster with only 256 MB RAM (since
  that much could be kept mapped all the time).
  Now we're using a different strategy: We have small pools of virtual
  page slots per CPU that are used for the physical page operations
  (memset_physical(), memcpy_*_physical()) with CPU-pinned thread.
  Furthermore we have four slots per translation map, which are used to
  map page tables.

These changes speed up the Haiku image build in Haiku significantly. On
my Core2 Duo 2.2 GHz 2 GB machine about 40% to 20 min 40 s (KDEBUG
disabled, block cache debug disabled). Still more than factor 3 slower
than FreeBSD and Linux, though.

020ac56840 * Fixed bug in the "scheduler" command: The check when a thread was
unscheduled was incorrect.
* Introduced _kern_analyze_scheduling() syscall. It requires scheduler
  kernel tracing to be enabled. It uses the tracing entries for a given
  period of time to do a similar analysis the "scheduler" debugger
  command does (i.e. number of runs, run time, latencies, preemption
  times) for each thread. Additionally the analysis includes for each
  thread how long the thread waited on each locking primitive in total.
* Added kernel tracing for the creation of semaphores and initialization
  of condition variables, mutexes, and rw locks. The enabling macro is
  SCHEDULING_ANALYSIS_TRACING. The only purpose is to provide
  _kern_analyze_scheduling() with more info on the locking primitives
  (the name in particular).

a9d7be0708 * Implemented mprotect(). A vm_area does now have an optional array
specifying the protection of each page (4 bits per page).
* Added no-op implementation of posix_madvise().
* Replaced a few "addr_t size" parameters by "size_t size".

57f2b5a013 * Changed the meaning of the {KERNEL,USER}_STACK_SIZE macros to not
include the guard pages. Adjusted the kernel and boot loader code
  accordingly -- the guard pages size is added/not removed respectively.
  The stack size passed to _kern_spawn_thread() is now the actually usable
  size, and it is no longer possible to specify a size smaller than or
  equal to the guard pages size.
* vm_create_anonymous_area(): Precommit two pages maximum -- a stack with
  only one page usable size obviously doesn't need two pages.

51daeb7147 - Fixed warnings
- Fixed deadlock in xsi_sem_undo - RecordUndo
- Fixed issue in xsi_sem_undo: if the semaphore set does not exist
anymore, ignore the request but do remove the process from the sUndoList,
which wasn't previously done.
- free() in ClearUndos was called with interrupts disabled
- when a semaphore set ends to exist, remove all it's sem_undo request as it's ID
will be reused in the future.

47ca7595ca First patch by Salvatore to implement XSI semaphores with a few changes
by myself:
* renamed xsi_do_undo() to xsi_sem_undo() (there is more to XSI than sems).
* Fixed coding style issues in sys/sem.h and xsi_sem.cpp.
* Added _kern_*() syscall prototypes to syscalls.h.
* Added a TODO in xsi_sem.cpp and xsi_semaphore.h about moving union semun to
  a shared header.
* Made the team::xsi_sem_undo_requests int32 - due to padding, it would have
  needed 4 bytes anyway; please always use specific types over int/short/long.
* xsi_sem_undo() now checks if it needs to do anything - the calls in team.cpp
  no longer needs to do this.

69dddbdea1 Initial work towards supporting IO APICs. This cannot work for PCI interrupts
though until we use ACPI for proper PCI IRQ routing through the IO APIC.
Therefore the IO APIC code path is not yet enabled and the IO APIC isn't used.
ISA interrupts would work though, as would PCI interrupts if you'd hardcode
them for your specific configuration.
Note that this change also modifies some parts in the bootloader and in the PIC
setup to make local APICs available even on non-SMP systems. This causes APIC
timers to be used instead the normal PIT if it is available (also on non-SMP
configurations).
Also fixes some general errors in SMP and PIC code as well as some code cleanup.

2965c99fea * Changed the _kern_exec() and _kern_load_image() syscalls. They expect
a flattened argument/environment buffer now. This simplifies the work
  for the kernel a bit, since it can just copy the buffer and check
  whether it looks OK instead of messing around with individual strings.
  The runtime loader also gets a flattened array.
* Set the maximum size of the arguments/environment buffer to 128 KB.
  When more arguments are passed, we fail with a proper error code
  (instead of just truncating the arguments as before).
* On exec*() the first argument was silently replaced by the given path
  name, which is not correct.

1c8de8581b * Added optional spinlock contention measurement feature. Enabled when
B_DEBUG_SPINLOCK_CONTENTION is defined to 1. It typedefs spinlock to a
  structure (thus breaking BeOS binary compatibility), containing a
  counter which is incremented whenever a thread has to wait for the
  spinlock.
* Added macros for spinlock initialization and access and changed
  code using spinlocks accordingly. This breaks compilation for BeOS --
  the macros should be defined in the respective compatibility wrappers.
* Added generic syscall to get the spinlock counters for the thread and
  the team spinlocks.

368167ede8 * Integration of the new driver architecture.
* Moved devfs from fs/ to device_manager/, and separated the legacy driver
  support from it.
* Removed fast_log module.
* There are a couple of (temporary) regressions, though:
  - legacy SATA and ISA IDE support is disabled, the drivers haven't been
    ported yet.
  - The not yet used ATA bus manager hasn't been ported yet, either.
  - AHCI changes have not been tested.
  - the listdev command has been removed from the build (as it currently
    doesn't work anymore).
  - device manager generated IDs currently are not freed anymore when a device
    node is removed.
  - generic drivers can't yet use the new driver architecture.
  - simple busses that do not support device types won't work yet.
  - legacy driver publishing/unpublishing (ie. what USB needs) has not been
    tested, and may be broken.

vm_page_write_modified_pages(), save that it only writes pages in the

  pages in the given cache's range for writing by the page writer.
* Added _kern_sync_memory() syscall and the msync() POSIX function.

6b202f4e3d * Introduced new header directory headers/private/system which is supposed
to contain headers shared by kernel and userland (mainly libroot).
* Moved quite a few private kernel headers to the new location. Split
  several kernel headers into a shared part and one that is still kernel
  private. Adjusted all affected Jamfiles and source in the standard x86
  build accordingly. The build for other architectures and for test code
  may be broken.
* Quite a bit of userland code still includes private kernel headers.
  Mostly those are <util/*> headers. The ones that aren't strictly
  kernel-only should be moved to some other place (maybe
  headers/private/shared/util).
