  1. map 64-bit PCI BARs at location provided by emulator 

    Currently 64-bit PCI BARs are unconditionally mapped by BIOS right
over 4G + RamSizeOver4G location, which doesn't allow to reserve
extra space before 64-bit PCI window. For memory hotplug an extra
RAM space might be reserved after present 64-bit RAM end and BIOS
should map 64-bit PCI BARs after it.

Introduce "etc/reserved-memory-end" romfile to provide BIOS a hint
where it should start mapping of 64-bit PCI BARs. If romfile is
missing, BIOS reverts to legacy behavior and starts mapping after
high memory.

  1. acpi: strip compiler info in built-in DSDT if any 

    IASL stores it's revision in each table header it generates.
That's a problem since guests see a change each time
they move between hypervisors.
We generally fill our own info for tables,
but we forgot to do this for the built-in DSDT.

  2. acpi: load and link tables through romfile loader 

    Load files through romfile loader and use for acpi tables.
We need the RSDP pointer to hang the rest of the tables off it,
to detect that we simply scan all memory in FSEG.

Add an option to disable this feature (useful for old QEMU versions).
This saves about 1Kbytes.

  3. romfile_loader: utility to patch in-memory ROM files 

    Add ability for a ROM file to point to
it's image in memory. When file is in memory,
add utility that can patch it, storing
pointers to one file within another file.

This is not a lot of code: together with the follow-up patch to load
ACPI tables from ROM, it's about 1K extra.

  2. license: allow QEMU to reuse acpi bits under GPLv2+ 

    You are getting this mail because you might have contributed code to one
of the files in seabios that we want to reuse in QEMU,
when this file was under GPLv3 or LGPLv3.

QEMU is GPLv2 at the moment, so as a step in the process of moving acpi
tables to qemu, we need to make sure the code we'll be moving is GPLv2
compatible.

The code was originally LGPLv2 in bochs so these bits are OK.

QEMU generally prefers GPLv2 or later, so this is what this
patch does. The plan is therefore:
- collect acks from everyone
- copy code to QEMU and apply this patch to QEMU copy only

If you allow the use of your contribution in QEMU under the
terms of GPLv2 or later as proposed by this patch,
please respond to this mail including the line:

	Acked-by: Name <email address>

in the message body.

Thanks!

  1. fix buildversion.sh 

    Recent git versions place the submodule git repos into the
.git/modules directory of the toplevel repo.  In that case
.git of the seabios tree isn't a directory, but a regular
file, saying where the gitdir is.

Extent the git check to also allow .git being a regular file,
so buildversion.sh works correctly when called within the qemu
submodule.

  2. usb: add xhci support 

    $subject says all.  Support for usb3 streams is not implemented yet,
otherwise it is fully functional.  Tested all usb devices supported
by qemu (keyboard, storage, usb hubs), except for usb attached scsi
in usb3 mode (which needs streams).

Tested on qemu only, tagged with QEMU_HARDWARE because of that.
Testing with physical hardware to be done.

  7. Add generic qemu detection 

    This patch adds support for detecting whenever SeaBIOS runs on qemu
or not.  This is done by looking at the northbridge (pci device 00:00.0)
and check the subsystem id.  Most pci devices emulated by qemu -- the
two northbridges i440fx and q35 included -- have a subsystem id of
"1af4:1100".

In case the subsystem ID matches set PF_QEMU, log a message (including
the northbridge found while being at it) and also check for kvm.
