Hi,
Turns out it's this:
commit 76e58028d28e78431f9de3cee0b3c88d807fa39d Author: Kevin O'Connor kevin@koconnor.net Date: Wed Mar 6 21:50:09 2013 -0500
acpi: Eliminate BDAT parameter passing to DSDT code. The "BDAT" construct is the only ACPI mechanism that relies on SeaBIOS reserved memory. Replace it with the SSDT based template system. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>That is most likely dsdt + bios.bin not being in sync. Simply using 'qemu -bios /path/to/seabios/out/bios.bin' doesn't fly due to qemu using a non-matching dsdt then.
With qemu/master you can just use 'qemu -L /path/to/seabios/out' instead and qemu will pick up both bios.bin and dsdt from the fresh seabios build directory then (and anything else it doesn't find there from the default locations).
Thanks, yes that's it. QEMU only seems to look in the -L path or the current directory for the missing files, so it's a bit messy but works. I'll just go ahead and roll a v3 of the VGA patch that converts to wmask since I'm muddied the waters on v2 here. Thanks,
