9a79e531ef bonefish+mmlr:
* Introduce TracingMetaData::IsInBuffer() to validate that a certain memory
  range is within the valid tracing buffer limits.
* Use that when validating in tracing_is_entry_valid() before trying to access
  the entry, resolving a TODO.
* Validate the candidate time against the handed in time (if specified) as an
  additional check.
* Tiny unrelated text cleanup.

45cbd81436 Fix build with tracing disabled. Since capture_tracing_stack_trace() doesn't
return a stack trace when tracing is disabled we don't really need to be able
to print one either.

Refactor the "allocations_per_caller" KDL command related functions.
They expect an instance of a class implementing the new
AllocationTrackingCallback interface, now. The only implementation ATM
is AllocationCollectorCallback, which does the work the now removed
slab_debug_add_allocation_for_caller() did before.

* Fix build broken in r43078. The slab_debug_add_allocation_for_caller()
  wasn't guarded correctly.
* slab_debug_add_allocation_for_caller(): Add bool resetAllocationInfos
  parameter, which makes the function clear the allocation tracking
  infos after processing the data.
* "allocations_per_caller" KDL command: Add option "-r" to reset the
  allocation tracking infos. The next invocation of the command will
  only show the allocations made after the reset.

  size from the caller infos instead of using return arguments in the
  helper functions called.
* Move caller info update code from analyze_allocation_callers() to new
  function slab_debug_add_allocation_for_caller(), so it can be reused.
* Add MemoryManager::AnalyzeAllocationCallers() to collect the
  allocation information for the memory manager.

e1c6140eaa mmlr + bonefish:
* Add optional stack trace capturing for slab memory manager tracing.
* Add allocation tracking for the slab allocator (enabled via
  SLAB_ALLOCATION_TRACKING). The allocation tracking requires tracing
  with stack traces to be enabled for object caches and/or the memory
  manager.
  - Add class AllocationTrackingInfo that associates an allocation with
    its respective tracing entry. The structure is added to the end of
    an allocation done by the memory manager. For the object caches
    there's a separate array for each slab.
  - Add code range markers to the slab code, so that the first caller
    into the slab code can be retrieved from the stack traces.
  - Add KDL command "allocations_per_caller" that lists all allocations
    summarized by caller.
* Move debug definitions from slab_private.h to slab_debug.h.

* Add tracing_find_caller_in_stack_trace(). Helper function to get the
  first return address of a stack trace that is not in one of the given
  address ranges.
* Add AbstractTracingEntryWithStackTrace::StackTrace() getter.
* Add tracing_is_entry_valid(). Checks, based on the additionally given
  time, whether a tracing entry is (probably) still in the tracing
  buffer.

fc2d7cb04d * Introduce {reserve|allocate|free}_io_interrupt_vectors() that can generically
be used to mark certain io interrupt vectors as reserved and to allocate from
  the still free ones. It is a kernel private API for now though.
* Make the MSI code use that functionality instead of implementing its own which
  slims it down considerably and also removes quite a bit of hardcoded knowledge
  about the interrupt layout that didn't really belong there.
* Mark the various in-use interrupts as reserved from the components that
  actually know about them (PIC, IO-APIC, SMP, APIC timer and interrupt setup).

* Add support for G5 PowerPC cpus...
* Refactor memory region code to be aware of 64-bit OF addresses.
  As-is the boot loader wouldn't start on G5 systems because
  OpenFirmware memory base addresses are stored as two 32-bit
  unsigned int 'cells' vs one 32-bit unsigned int 'cell' on G3/G4.
  I removed the static struct and replaced it with a template
  and pass uint32 or uint64 depending on the address cell size.

961a96a987 Optimize the configuration of the port heap. Previously the max bin size was
512 bytes with a heap page of 2048 bytes resulting in excessive waste for
allocations between 512 and 1023 bytes. Also tune the requested alignment so
that sizeof(port_message) (currently 28 bytes) can occupy one allocation unit
without waste.

3fb17998a7 When resizing an area that has individual page protections (set via mprotect),
we have to enlarge/shrink the array that holds them and assign a protection
value for the additional pages as necessary. Otherwise we'll access invalid
memory when looking up page protections for enlarged areas and get random
protection values.
Experienced with QEMU that sets page protections via mprotect on heap memory.
When the heap was later enlarged, write access to the additional memory would
result in permission denied errors and crashes.

debugger. As sInDebugger is already > 0 when the first CPU enters KDL, code
  from other CPUs might see debug_debugger_running() == true already before they
  enter the debugger.
* Instead, move the sDebuggerOnCPU setting out of the debugger loop and hold the
  value until after calling exit_kernel_debugger() so that the exit hooks still
  see debug_debugger_running() == true.
* Also avoid calling exit_kernel_debugger() when we've been called recursively
  (previousCPU != -1). Previously the exit hooks would've been called and the
  debugger state reset erroneously. To balance the missing decrement of
  sInDebugger in that case we decrement sInDebugger in enter_kernel_debugger()
  also when detecting the recursion case.

3214710036 Use sInDebugger instead of sDebuggerOnCPU to determine if the debugger is
running. The former has a broader scope and lasts until the debugger exit is
actually done whereas the latter is already reset when the inner loop is exited.
This fixes the issue Ingo saw where the USB physical memory manager wasn't able
to free resources used for the debug transfer. It has reserved debug memory that
it uses depending on debug_debugger_running() and was therefore confused when
it returned false when called from the kernel debugger module exit hook.

2b86134925 * Actually include an offset to write to in writev_port_etc(). It would
previously just always write over the beginning of the buffer for each vector.
  Since the writev version isn't exposed to userland by means of a syscall and
  kernel internally nobody used it, nobody noticed so far.

cd3e02ca1e * Growing the port heap by adding new areas was broken in various ways. For one
the acquired quota in sTotalSpaceInUse wasn't released in all cases leading to
  it eventually reaching the limit (after a _very_ long time though, so this is
  more theoretical than anything else). The sAllocatingArea flag wasn't reset in
  the case that an area was already added in the meantime, resulting in no
  further growing being possible. Then there were race conditions between
  waiting for space to become available and the situations which made that space
  available (freeing port_messages and adding new areas).
* Fix these race conditions by using a mutex (sPortQuotaLock) to protect the
  various quota and allocation related variables. Instead removed the atomic_*
  operations that were previously used.
* Had to move some static functions around.

Should make port heap growing more robust, even though in normal use you'll
likely never encounter it...

f84387d6c4 _user_initialize_partition(): After performing the operation don't set the new
disk system, if the partition already has a disk system set. This can happen
when the disk system's initialization function is lazy and just lets the DDM
rescan the partition. In bad cases the previous disk system has a higher
priority than the new one and, if its on-disk structures have not been
destroyed, it will win the rescan. Not setting the disk system in such cases at
least leaves the partition object in a consistent state.

* Changed the semantics of the debugger_module_info::debugger_getchar() hook.

  achieve that. It does now start, check, or cancel a transfer. Split
  UHCI::ProcessDebugTransfer() into StartDebugTransfer(), and
  CheckDebugTransfer() accordingly, and also added a CancelDebugTransfer().
  The latter seems to have issues. Michael, please have a look. I have no clue

  functions/semantics. This allows to use any input (USB, PS/2, serial) in KDL.
* Removed the no longer needed "serial_input" command.
* read_line(): Also support 0x7f as backspace code. That's what xterm sends.

c4b692da1a Revert r42105. The rsdt_length field on the rsdp structure we have declared is
actually misleading, since it specifies the length of the xsdt rather than the rsdt. Furthermore, it is only available if the BIOS reports ACPI version 2.0 or greater. Since we don't currently support the XSDT, we can't rely on that field and have to resort to the previous approach of mapping the RSDT header in order to determine the length of the RSDT itself.

Also add validation of the RSDT's checksum so we don't get tripped up by BIOS's with broken tables.

Should fix boot problems that were introduced by r42105.

2e8aa19c63 * The boot loader does now set up an IDT that allows it to catch processor
exceptions (page faults and the like). The handler dumps possibly interesting
  information (registers, a (numerical) stack trace) to the serial output, and,
  if possible, also to the screen. That should help debugging boot loader
  crashes.
* For the IDT the boot loader sets up for the kernel the descriptors are set up
  the same way, so until the kernel initializes the IDT itself (arch_init()) the
  facility is still in place and can thus catch very early kernel boot crashes.
  Unfortunately the on-screen output doesn't seem to work anymore at that point,
  so the output only goes to the serial port...
* ... and to the debug syslog -- dprintf() does now append it there after
  debug_cleanup() has been called. Seems to work fine in qemu, but when I tested
  it on real hardware the debug syslog was gone.

cb80e931f6 * Turn around finding the routing table on a PCI bridge and checking for it to
actually be a bridge. We always want to check if the device at hand is a PCI
  bridge, because in that case we need to recurse further down. We recurse now
  even if there is no routing table found for the current bridge, since that
  doesn't mean that another bridge, further below, can't have a routing table
  again. Possibly fixes #7520.
* Fix the matching function to just check for function 0 to be present instead
  of classifying it. Previously if there happened to be a cardbus bridge on
  function 0 of a multi function device, the rest of the functions of the device
  would've been ignored because we returned early due to the unsupported bridge.
* Only hand down the current bus number when recursing as that makes it clearer
  what's going on instead of handing in a partially filled out pci_address
  structure and then filling in other parts inside the function.
* Commented out getting the segment number as we don't support it at all.
* Extended debug output.

8837310ce7 * Slightly alter the semantics of the input gathering function to take the
menu item it's associated with rather than an input string. This allows it
  to calculate the position to start the input at, as well as the correct
  line to place it on. The previous solution always put the input at the
  center line, which happened to be the right place by happy coincidence
  unless one also had the menu items for viewing/saving the debug syslog
  present.
* Implement input buffer scrolling, and consequently lift the previous size
  limit on user input (it is now only limited by the size of the passed in
  buffer).
* Implement parsing of the input buffer to allow it to handle comma-separated
  options. Thus, one can now input things like "disable_smp true, serial_debug_output false"
  and it will be handled properly.

2c0d5258df Of course the PIC mask register is a _mask_ and the enabled interrupts are the
ones that aren't masked. This reversed the enabled interrupts and therefore
disabled the already installed ACPI SCI handler and wrongly enabled the other
interrupt pins instead on PIC to IO-APIC handover. Probably fixes #7525.

2ae3d5121c Switch to using the PIT in mode 0 (interrupt on 0) instead of mode 2 (rate
generator). There are chipsets (namely ATI/AMD SBx00) where mode 2 doesn't seem
to work (the counter isn't reloaded after the countdown has completed). Mode 0
has the same resolution as mode 2 and, as interrupts are disabled at this point
in booting, is otherwise equivalent as well. I've tested this on 5 machines
available to me and it doesn't seem to have any negative effect.

7adc7269d8 * Re-program the timer for each loop instead of waiting for it to wrap around.
With that we will usually start right away without having to wait for the
  timer to be in the desired state, which removes roughly 116ms of spinning
  around for a normal calibration run.
* Read back the value once after programming. The delay this introduces
  accounts for the fact that the counter will only start counting down on the
  next clock cycle.

active config and update the info for the remaining shared link device
  entries. Seen on KVM for the (PCI) ACPI interrupt, but happens where there is
  no _SRS method for a device (as this one is optional). I find that a bit
  strange however as in such a case no _PRS (possible resources) should be
  present either, especially not one advertising a config different from the

Scrolling of the input buffer is not yet supported (will implement that

shouldn't be a problem for our current set of options though.

fb5a1727f4 * Implement interrupt source overrides. We install a relay interrupt handler
at the override entry to trigger the overriden vector so that we don't need
  to configure any additional redirections.
* Also configures the polarity and trigger modes found in the override entry.
* When disabling the legacy PIC, retrieve the enabled interrupts and re-enable
  then in the IO-APIC. This will for example make the ACPI SCI work that is
  installed prior to switching interrupt models. Through the transparent support
  for interrupt source overrides it'll also automatically relay from the old to
  the new vector.

This should make ACPI interrupts work and should support relocating the ISA PIT
from irq 0 to a different global system interrupt (usually 2) so that it can
still work when IO-APICs are in use.

192bc027ea Disabling the local APIC also means disabling SMP, as the APIC is the base for
all inter-CPU messaging. The previously described timekeeping is just an extra
function of local APICs. Before, if you'd select "disable local APIC" it would
still blindly write to invalid memory (targetting the non-mapped local APIC) and
then just hang waiting for the other CPUs (that were obviously not responding
to the init sequence that wasn't programmed).

e21407d07b When applying settings from the boot menus, aggregate them and then add them
to the kernel args in a single go. Otherwise we wind up with more link list
entries than expected, which in turn resulted in settings not quite being
parsed properly upon entering the kernel, which meant that if options were
chosen in both the debug and safe mode menus, only the debug ones were
applied. This might also have resulted in the kernel settings not being
loaded correctly in such an instance.

Should fix various issues people have had with safe mode settings not being
applied properly.

8908aef9c2 * Don't map the IO-APIC within the bootloader. We don't need it to set up SMP
at all and, since there can be multiple IO-APICs, we need to do the
  enumeration again in the kernel anyway. Also only set ioapic_phys the first
  time we encounter an IO-APIC object as it looks cleaner when we arrive at the
  first IO-APIC default address.
* Therefore we don't have to worry about already mapped IO-APICs when
  enumerating them in the kernel.
* Also remove the mapping function that is now not used anymore.
* We still use the ioapic_phys field of the kernel args to determine whether
  there is an IO-APIC at all to avoid needlessly doing the enumeration again.

This fixes multi IO-APIC configurations, because before we would indeed map
the last IO-APIC listed in the MADT, but then in the kernel assumed we mapped
the first one. We'd end up with mapping the last listed IO-APIC twice and the
first IO-APIC never, always programming the last one when we actually targetted
the first one.

if not we will simply fail at the routing preparation stage where we can still
fall back gracefully. This makes things a bit more error resilient.

eda743903e Provide an interrupt availability check callback instead of a maximum IRQ
number. This accounts for possible gaps in the IO-APIC GSI mappings. Since most
of the time there will be only a single IO-APIC the extra overhead is relatively
small.

d11e32a807 Enumerate IO-APICs using the ACPI Multiple APIC Descriptor Table (MADT). We do
the same for the first IO-APIC in the bootloader (also using the MADT), but
here we can use the ACPI module. The enumerated IO-APICs are added to the list
and should be usable from there on. For lack of hardware I wasn't able to really
test that though.

af2da315dc Fix the larger problem that was hiding behind the build problem of set_haiku_revsion on FreeBSD:
* the length of the sHaikuRevision character array symbol needs to be set explicitly,
  as using either _SYS_NAMELEN or sizeof(utsname::version) will only return the values
  for the host, which may not match ours, thus potentially causing problems when using
  sHaikuRevision
* add headers/private/system_revision.h which defines SYSTEM_REVISION_LENGTH to 128
* adjust definitions of sHaikuRevision in libroot and kernel accordingly
utsname::version is shorter than SYSTEM_REVISION_LENGTH, but that doesn't cause any harm
until we have indeed switched to a DVCS (in which case longer revision strings will be 
cut off by 'uname').

  This doesn't guarantee optimal results as some link devices may not be
  configurable to some IRQs and we might fill up their slots this way. Most of

* Take the BIOS assigned IRQ white list into account when assigning IRQs in the
  ISA range and avoid assigning to non white listed IRQs. Quite probably it'd be
  ok to use all of the IRQs present in the possible IRQ list, but let's play it
  safe...

  reconfiguration.
* Some cleanup, use references instead of pointers where applicable.

configuration that doesn't require any link device changes and will only
  prepare for updating the pci_info. Enabling then does the link device setup
  and updates the pci_info with the new IRQ values.
* Configuring link devices now takes into account that multiple devices may
  share a single link device, meaning that the sharing PCI devices can't be
  configured independently.

We still only blindly configure the first possible IRQ on the link devices, but
now we actually have all the information to change that. Working on that next.

Those can be used to white list PCI IRQs in ISA space (<= 15) as those are
basically guaranteed not to overlap with ISA devices. Those white listed entries
can then be used if we only have a 16 pin IO-APIC or if there are only legacy
IRQ resources available for configuration (i.e. ones with bitmasks of 16 bits,
limiting their range to IRQs 0-15).

c2507ed4ae Actually use the ACPICA headers to get at the correct types instead of

IRQ resources because the alignment of the structs were different in our local
duplicates...
Brings in the ACPICA naming sheme and isn't really clean either. So all of the
reconfiguration should probably just be moved into the ACPI bus_manager.
On the plus side we can now use the proper descriptive macros instead of the
hardcoded numbers which fixes a few of the TODOs.

d3e3ae8edc Implement a very naive configure_link_device() function that just blindly sets
the first possible configuration. This will probably result in a "everything
mapped to a single IRQ" situation, but should get systems that make use of link
devices in APIC mode at least running.
To make more sensible decisions the interface has to be changed next as it
currently doesn't allow to get anything but the very first possible config.

2a127b718c Reimplement the IRQ setting function. Based on the template we get from current
resources we input the desired configuration and then set them. Note that the
set_current_resources() ("_SRS") method is pretty picky (on the low-level ACPI
side) and needs the configuration in exactly the form get_current_resources()
("_CRS") returns, so that's why we need to utilize that buffer as a template.
Looking at FreeBSD there seem to be systems that don't actually provide a
"_CRS", where we will need to fall back to using the get_possible_resources()
("_PRS") data to construct a valid template...

option reenabled.

8c804ef2d6 * Added functionality to resolve the addresses provided in the IRQ routing table
to PCI devices partly using the new ACPI interface and by using bridge config
  information from PCI.
* Added lookup of matching device/pin combinations and update of the relevant
  interrupt line variable via the new PCI module function. This means that the
  Global System Interrupt (GSI) that is used after switching to the IO-APIC is
  now stored in the PCI config space and drivers enumerating these devices will
  now attach their interrupt handlers to the right IRQs.
* Resolve all relevant interrupt information directly into the irq_routing_entry
  so that can be used as the single source for config information. This includes
  resolving the current setting of any PCI link devices into the irq field that
  represents a GSI now.
* Use that info to configure interrupts in arch_int.cpp and remove the logic
  there.
* Some cleanup and added debug output.

This implements the final missing part for using IO-APICs and full APIC mode for
interrupt routing. Note that there is no quirk handling of any form, so this
may very well not work on some configurations. Note also that I have tested this
only on one machine so far. Once proper testing is done the default of disabling
the IO-APIC can be removed.

  extra conversion from bitfield to irq number.
* Add and handle extended irq structures.
* Disable the legacy PIC when done configuring the IOAPIC. Since during that
  configuration the ACPI module is initialized, the ACPI SCI is still enabled
  in the PIC instead of the IOAPIC. We'll have to delay that routing in the
  ACPI module for it to work.
* Correctly handle the fixed IRQ case for the PCI interrupt routing (hopefully).
* Actually allow for enumeration of possible IRQ settings. Not yet used though.

All of this brings us a bit closer, though it still won't work for PCI
interrupts. ISA interrupts work fine through the IOAPIC as far as my hardware
goes, but PCI interrupts are connected to dedicated IOAPIC pins and I still
haven't figured out how to determine their exact routing.

8775d8d25d dir_remove() now handles a path which ends with "/./" and fixed #6817.
Another way would be to disallow removing such a path, as Linux does.

e8226ce48d * fix support for influencing tzset() via TZ environment variable
(now at least <std> and <offset> are supported properly)
* instead of creating a TimeZone object whenever needed, we now
  create it in tzset() and keep it around
* add tests for TZ to locale_test

548836e4f8 * if ioctl hook wasn't found, now returns B_DEV_INVALID_IOCTL
* in case fd_ioctl() was about to return B_DEV_INVALID_IOCTL, translate to ENOTTY to satisfy #7279.

3116b031dc FIONBIO and FIONREAD don't apply to directories, files, attributes: returns ENOTTY in these cases. This fixes #7279.
ENOTTY could also be replaced with a B_ error code.

bafa759148 now correctly init the thread id in the pthread struct for main thread and threads spawned with spawn_thread(). This definitely helps for #7235.

3d0d4b6200 * Implemented a way to specify additional debug options via MALLOC_DEBUG when
using libroot_debug.so, instead of having to hardcode them in the application
  via calling private heap functions.
* The following options are implemented: 'p' turns on paranoid validation,
  'w' triggers periodic wall checking every 500ms ('W' does the same, but every
  100ms), 'g' to use guard pages (beware, this will dramatically increase
  memory usage), and 'r' which forbids reusing of memory, freed memory is never
  actually freed.
