Dear coreboot folks,
searching for ACPI in the output of `dmesg` I noticed the following
message.
$ uname -v
#1 SMP Debian 3.2.35-2
$ dmesg | grep -i acpi
[ 0.154063] ACPI: BIOS offers _BFS
[ 0.154067] ACPI: If "acpi.bfs=1" improves resume, please notify
[email protected]
Doing
$ git grep _GTA
reveals that it is only implemented in the DSDT of AMD based boards. As
resuming currently does not work on the ASRock E350M1 [1], I cannot test
that.
Was this ever tested by adding `acpi.bfs=1` to the Linux kernel command
line and what was the outcome? A test on AMD Persimmon would be very
interesting.
It looks like support for this has been removed in the meantime though

ACPI: delete _GTS/_BFS support
since Linux Git tag v3.6-rc2.
Thanks,
Paul
