The 1.7.4 version of SeaBIOS has now been released. For more
information on the release, please see:
http://seabios.org/Releases
New in this release:
* Support for obtaining ACPI tables directly from QEMU.
* Initial support for XHCI USB controllers (initially for QEMU only).
* Support for booting from "pvscsi" devices on QEMU.
* Enhanced floppy driver - improved support for real hardware.
* coreboot cbmem console support.
* Optional support for using the 9-segment instead of the e-segment
for local variables.
* Improved internal timer code and accuracy.
* SeaVGABIOS improvements
* Better support for legacy X.org releases with incomplete x86emu
emulation.
* Support for using an internal stack to reduce caller's stack
usage.
* Back port of new "bochs dispi" interface video modes.
* Several bug fixes and code cleanups
* Source code separated out into additional hardware and firmware
directories.
* Update to latest version of Kconfig

FYI, I've added a few pages to the wiki with some high-level
information on the internals of SeaBIOS:

This is still a work in progress.

Note this is not the APIC base address, that one is 80h on the ISA
bridge (function 0). You're changing the behavior for 80h on the power
management function, which is function 3. The register is "PMBA—POWER
MANAGEMENT BASE ADDRESS" and it is indeed initialized by SeaBIOS in
piix4_pm_setup (src/fw/pciinit.c).
Michael, perhaps a part of pci_setup (same file) should run on S3 resume?

Hi,
qemu 1.7 is almost out of the door. I want update seabios early in the
1.8 devel cycle. Time to do resume the release planning since we've
scratched the idea to do a last-minute bios update for 1.7.
I'd like to see a seabios release from the master branch in december.
Ideally we'll put a prerelease into qemu before the final release so we
get some testing. We could either explicitly tag a release candidate or
just grab a snapshot for that.
Commit pending patches, enter seabios freeze, prepare seabios update for
qemu can be done next week I think. Then have 2-3 weeks freeze period,
tag final release before xmas. In case something doesn't go as planned
early january.
Pending patches:
* my ahci and pci patches sent this week.
* anything else?
How we wanna call the baby? 1.7.4? 1.8.0?
cheers,
Gerd
This is a reminder that we are planning to release the next version of
SeaBIOS (v1.7.4) in the next few days. If you are aware of any
significant defects in the current git repo, please raise them now.
Thanks,

FYI, I have committed this patch.
