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...

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.

* 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

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

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

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

* 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

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.

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.

functional change intended.
* Use an appropriately sized sLevelTriggeredInterrupts for each controller type.
This also fixes an out of bound access for IO-APICs with more than 32 entries
and also returns the right mode in such cases.

* 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').

already. This allows to detect invalid settings before starting to enable
IRQ routing and therefore allows to gracefully fall back to PIC mode on error.
* Actually read the number of IO-APIC entries before using that number in
routing preparation.

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.

independently. Matching will happen first to enumerate and match all devices.
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).

using the already parsed pci_info data from the PCI module. This removes the
need to iterate over all of the pci_infos for each routing table entries which
makes this an order of magnitude less expensive. Heavily inspired by the
corresponding FreeBSD code.

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.

* increase _SYS_NAMELEN defined in sys/utsname.h to 128 to allow long(ish) revisions

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...

for the introduced get_pci_info() method in ACPI as it doesn't work reliably.
The new version should be more robust and efficient as it only resolves the
root bridge values once.
* Don't try to read and use the secondary bus register for the root bridge as
it isn't actually a normal bridge. We get the root bridge bus by using the
Base Bus Number (_BBN) method.
* Rewrite the logic to recurse down to all busses.

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.

resolved to symbols in the application, which is usually undesired. Weak
symbols have the same problem, but the the runtime loader cannot decide which

The root issue is that BeOS style add-ons simply cannot be supported by a
standard-complying ELF loader.

solution for the time being would be to build gcc 4 add-ons with default
