Hi,
Digged out an old patch from the mailing list, to make smm use
acpi_pm1a_cnt. This allows to make the acpi pmbase a variable
and figure where to place the registers at runtime.
With these preparations in place we can go move acpi pm registers
below 0x1000 for new enougth qemu (2.0+). The whole 0x1000 -> 0xffff
range is free then on q35.
The series looks okay to me.
I am a little leery about the way patch one accesses the f-segment
while in SMM mode. I do the same in my 32bit driver test series -
see:
https://github.com/KevinOConnor/seabios/commits/testing-32bit-drivers
. But, I'm leery about making that kind of change days before tagging
a new release.
I think that code can be removed altogether, it should be handled by
QEMU. See the series I just posted.
Paolo
