allow CPUs to have non-contiguous Local APIC IDs (v2)
Extract Local APIC IDs directly from the CPUs, and instead of check for
"i < CountCPUs", check if the APIC ID was present on boot, when building
ACPI tables and the MP-Table.
This keeps ACPI Processor ID == APIC ID, but allows the
hardware<->SeaBIOS interface be completely APIC-ID based and not depend
on any other kind of "CPU identifier". This way, SeaBIOS may change the
way ACPI Processor IDs are chosen in the future.
As currently SeaBIOS supports only xAPIC and not x2APIC, the list of
present-on-boot APIC IDs is a 256-bit bitmap. If one day SeaBIOS starts
to support x2APIC, the data structure used to enumerate the APIC IDs
will have to be changed (but this is an internal implementation detail,
not visible to the OS or on any hardware<=>SeaBIOS interface).
For current QEMU versions (that always make the APIC IDs contiguous),
the OS-visible behavior and resulting ACPI tables should be exactly the
same. This patch will simply allow QEMU to start setting non-contiguous
APIC IDs (that is a requirement for some sockets/cores/threads topology
settings).
Changes v1 -> v2:
- Use size suffixes on all asm instructions on smp.c
- New patch description
report real I/O APIC ID (0) on MADT and MP-table (v3)
When resetting an I/O APIC, its ID is set to 0, and SeaBIOS doesn't
change it, so report it correctly on the ACPI MADT table and MP-table.
Some hardware may require the BIOS to initialize I/O APIC ID to an
unique value, but SeaBIOS doesn't do that. This patch at least makes the
tables reflect reality.
Changes v2 -> v3:
- Fix MP-table too, not just ACPI MADT table
Changes v1 -> v2:
- Cosmetic: whitespace change (removed extra newline)

This patch adds support for the lsi53c895a scsi host adapter,
allowing seabios to boot from scsi disks and cdroms connected
to the lsi scsi hba emulated by qemu.
This driver was written by looking at the expectations of qemu's
lsi emulation. I have no idea idea how close this is to work on
real hardware, and I somehow doubt anyone cares given the age of
physical lsi scsi cards. It depends on !COREBOOT for that reason.
This patch adds support for booting from UAS (usb
attached scsi) devices.
For now only usb 2.0 support is there. On usb 3.0 the
UAS protocol uses streams, so changes will be required
to make usb 3.0 devices fly once we have a xhci host
controller driver.
So far the driver has been tested on qemu-emulated
virtual hardware only. In theory should just work on
bare metal too.
Enable bit 15 (USE_PLATFORM_CLOCK) of FADT flags field so that
older Windows guests do not make use of the TSC for timestamping.
From the ACPI manual:
"A value of one indicates that OSPM should use a platform provided timer
to drive any monotonically non-decreasing counters, such as OSPM
performance counter services. Which particular platform timer will be
used is OSPM specific, however, it is recommended that the timer used is
based on the following algorithm: If the HPET is exposed to OSPM, OSPM
should use the HPET. Otherwise, OSPM will use the ACPI power management
timer. A value of one indicates that the platform is known to have a
correctly implemented ACPI power management timer."
Problems using the TSC include:
1) Migration to a host with different frequency.
2) Unsynchronized TSCs in SMP hosts (KVM does not guarantee
synchronization).
3) Processors which do not increment TSC on low power states.

update bios date
Linux ignores some information from acpi in case the bios is old

go for something more recent. With this patch applied the
ressources for \\SB.PCI0 will show up in /proc/{iomem,ioports},
tagged as "PCI Bus 0000:00".
The winxp boot loader does something curious - it sets an int 0x1c
handler, records the stack location, and then spins in place with irqs
enabled. The 0x1c handler alters the memory just past the stack
pointer so that when the timer irq returns the code jumps to a new
location and stop spinning. The winxp code relies on the fact that a
hw irq will always place 6 bytes at a specific location and that it
can alter those bytes.
The ecdc655a patch does a full backup/restore of the register state.
Unfortunately, the restore overwrites the changes made by the winxp
0x1c handler.
This patch reverts much of ecdc655a. Hardware irqs are still handled
on the extra stack, but only the essential register state is backed up
and restored.
Also, stack_hop_back is changed to only use %sp when changing states -
this enables the entry code to store just %esp instead of both %esp
and %sp.
