[PATCH] x86: trim ram need to check if mtrr is there v3
H. Peter Anvin wrote:
Looks like the code doesn't check that the CPU *has* MTRRs...
so more strict check if mtrr is there really.
bail out if mtrr all blank when qemu cpu model is used
and check if is AMD as early
also remove 4G less check, according to hpa.
thanks, applied. Shouldnt we put in an exception for when there is MTRR
support, but they dont cover anything. Still emit a warning - but
booting up real slow is still better than losing all of RAM and crashing
The problem is re-occuring for me with current x86.git. Looks like v2
did the trick, and v3 is broken...
so the ram size less 4g is way out for your case.
again, can you post /proc/mtrrs with v2 patch?
It was empty. But ignore this report; it wasn't against the right
version of x86.git.
