I didn't know this had been tested. It's a little difficult for me to
keep track of all mail in the list.
says [only?] FAM10 revisions B0-B3 are supported.
My Phenom II X4 910e is rev RB_C3 and still doesn't boot (although I
no longer think it's the CPU but the southbridge, I can't confirm
either until I can boot).
all Phenom II X6 would be revision E0 (one could look at more authoritative
In theory many revisions should work. In practice there are some
constants in src/northbridge/amd/amdmct/amddefs.h which allocate one
bit in a 32 bit value for each revision. Then these are used to build
masks to test whether to apply workarounds for CPU errata or
particular initializations (like in
src/cpu/amd/model_10xxx/defaults.h). Some revisions (beyond HY_D0, I
think), don't fit in these 32 bits. I suspect those revisions may not
work, but maybe these revisions might work because they
just don't need workarounds, etc. I even sent some patches that would
only make sense for revision E and they were committed, but I couldn't
test them (I sent them precisely because I thought no revision E CPU
had been used with coreboot, so I couldn't break anything that worked before,
just hopefully add a small part to support future work).
It might be good to collect a list of tested CPU revisions and maybe
any issues found or any tests performed, if the supported chipsets
page is out of date for FAM10.
I'm sorry I can't contribute to this list though, until my board boots.
P.S. Whether E0 works or not, there's good documentation for it, so it
