SubjectCALL for testing on AMD
  Hi, all. I'd like to start out by thanking people who have responded
to my call for testing on AMD CPUs. Unfortunately, all the respondents
have AMD K6-2 stepping 7 and below. AFAIK, MTRR support is only
available for AMD K6-2 stepping 8 and above. So I'm resending my call
for testing.

If your /proc/cpuinfo reports AMD K6-2 stepping >= 8, then please try
out my patch. If you have a lesser CPU, don't bother anymore (I think
we've established that people with lesser CPUs are not affected:-).

The original call follows:

> Hi, all. I'm asking for people with AMD CPUs to please try my latest
> MSR patch. I've laid the foundation for AMD support in the MTRR driver
> (in preparation for merging a patch from Alan Cox), and I'd like to
> get some testing done before I proceed.
>
> So if you have an AMD CPU, please apply the patch and send me the
> contents of /proc/cpuinfo with and without the patch. Note that the
> patch doesn't add MTRR support yet: it just does some groundwork.
>
> The patch is available at:
> http://www.atnf.csiro.au/~rgooch/linux/kernel-patches.html
>
> and is against 2.2.2+devfs. If you have a non-devfs kernel, that's OK
> too, you'll just get a few failed hunks in the credits and
> ChangeLog. It doesn't actually break any code. So applyling the patch
> against plain 2.2.2 will be fine.
>
> BTW: make sure you set CONFIG_MTRR=y.
>
> Also make sure you set CONFIG_MSR=n and CONFIG_PERFMON=n if you
> patched against 2.2.2 only (i.e. no devfs).

Regards,

Richard....
