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

see debug_debugger_running() == true.
* Also avoid calling exit_kernel_debugger() when we've been called recursively

debugger state reset erroneously. To balance the missing decrement of
sInDebugger in that case we decrement sInDebugger in enter_kernel_debugger()

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.

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.

bridge, because in that case we need to recurse further down. We recurse now

* 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.

function of local APICs. Before, if you'd select "disable local APIC" it would

entries than expected, which in turn resulted in settings not quite being

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

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.

to determine if that vector is possibly taken by an IO-APIC. If IO-APICs are
not used, this will simply always return false, leaving all vectors free for
MSI use.
* The msi_init() now has to be done after a potential IO-APIC init, so it is now
done after ioapic_init() instead of inside apic_init().
* Add apic_disable_local_ints() to clear the local ints on the local APIC once
we are in APIC mode (i.e. the IO-APIC is set up and we don't need the external

if not we will simply fail at the routing preparation stage where we can still

* 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

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

hardwired GSIs and updated on configuring the link devices, is used for that.
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
the time this should be good enough though.
* 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...
* Also white listed are the IRQs that were set on the link device before
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.

Updating will happen after configuring all link devices, so once we know the
final GSI of all entries. The info about matching functions is kept in a
bitmask in the table entry.
* Move routing table entry handling out of the loop into it's own function to
faciliate early returns.

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).

duplicating the structs on our side. IRQ assignment didn't work with extended
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.

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.

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...

IO-APIC can be easily enabled to test it on various configurations. Note that
the previous default opt-out didn't work because the safemode options would not
be touched at all when not actually entering the boot menu.
Once IO-APIC is more broadly tested this can be removed again and the opt-out
option reenabled.

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.

correct PCI IRQ routing table for that mode. With this, we finally get the right
PIRQ <-> Global System Interrupt mapping and can therefore program the right
IO APIC entries. The only missing part now is to fix up the pci_info of the
devices with the then active GSI.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@41338 a95241bf-73f2-0310-859d-f6bbb57e9c96
* The irq values we get from ACPICA are already converted, remove the wrong
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.

directly. This saves the time for the hash table lookup and also works
around broken files like SoundPlay. Fixes the runtime loader part of #7094.

* The team and thread kernel structures have been renamed to Team and Thread
respectively and moved into the new BKernel namespace.
* Several (kernel add-on) sources have been converted from C to C++ since
private kernel headers are included that are no longer C compatible.
Changes after merging:
* Fixed gcc 2 build (warnings mainly in the scary firewire bus manager).

In r21611, about 3 years ago, the switch into protected mode was moved
from stage1 to stage2, which makes stage1 obsolete. You have to use
"pxehaiku-loader" when booting Haiku by PXE on x86.
Trying to use stage1 to boot stage2 resulted in tripple fault during
setup of ss segment, because stage1 switches to protected mode before
calling stage2, but stage2 expects real mode. The documentation is not
up to date.

* no longer expect a ICU timezone ID in the TZ environment variable,
but only expect this format if the TZ-value is starting with ':'
* accept "standard" TZ-values like "EST5" (of which only "EST" is
relevant to us) - if such a value is specified, we hardcode the
timezone name to the given value, no matter how ICU calls it

- This is mostly a copy of the x86 32bit paging method and infrastructure, this was copied for two reasons:
1) It is the most complete VM arch
2) The first ARM PAE patches have landed on alkml, so we will have to deal with it in the future as well,
and this infrastructure has proven to be ready ;)
- No protection features, or dirty/accessed tracking yet
- Lots of #if 0
but....
It boots all the way up to init_modules() now, and then dies because of a lack of (ARM) ELF relocation implementation!
Since at this point the VM can be fully initialised, I'm going to focus on CPU exceptions next, so we can get KDL to trigger
when it happens, and I can actually debug from there ;)

* x86_handle_debug_exception(): When encountering a syscall single-step, also
set the THREAD_FLAGS_DEBUG_THREAD thread flag. Otherwise the
B_THREAD_DEBUG_STOP would be ignored.
* x86 interrupt handling, DISABLE_BREAKPOINTS():
- Renamed to STOP_USER_DEBUGGING().
- Now it also call x86_exit_user_debug_at_kernel_entry() when
THREAD_FLAGS_SINGLE_STEP is set, so that the debug registers are saved.
