radeon: Fix disabling PCI bus mastering on big endian hosts.

2012-01-26T00:13:12+00:00

commit 3df96909b75835d487a9178761622b0cbd7310d4 upstream.

It would previously write basically random bits to PCI configuration space...
Not very surprising that the GPU tended to stop responding completely. The
resulting MCE even froze the whole machine sometimes.

Now resetting the GPU after a lockup has at least a fighting chance of
succeeding.

drm/radeon/kms: disable writeback on pre-R300 asics

2012-01-26T00:13:12+00:00

commit 28eebb703e28bc455ba704adb1026f76649b768c upstream.

We often end up missing fences on older asics with
writeback enabled which leads to delays in the userspace
accel code, so just disable it by default on those asics.

drm/radeon/kms: workaround invalid AVI infoframe checksum issue

2012-01-26T00:13:11+00:00

commit 92db7f6c860b8190571a9dc1fcbc16d003422fe8 upstream.

This change was verified to fix both issues with no video I've
investigated. I've also checked checksum calculation with fglrx on:
RV620, HD54xx, HD5450, HD6310, HD6320.

If we end up with no power states, don't look up
current vddc.

drm/radeon/kms: bail on BTC parts if MC ucode is missing

2011-12-22T12:28:01+00:00

We already do this for cayman, need to also do it for
BTC parts.  The default memory and voltage setup is not
adequate for advanced operation.  Continuing will
result in an unusable display.

drm/radeon/kms: Skip ACPI call to ATIF when possible

2011-12-01T09:57:34+00:00

I am under the impression that it only makes sense to call the ATIF
method if the graphics device has an ACPI handle attached. So we could
skip the call altogether if there is no such handle.

drm/radeon/kms: Hide debugging message

2011-12-01T09:57:03+00:00

Use the proper macro to issue the debugging message in
radeon_atif_call(). Otherwise we spam the log of many systems with a
message which looks like an error message of unknown origin, and could
thus confuse the user. Commit dc77de12dde95c8da39e4c417eb70c7d445cf84b
was a first step in this direction, but was not sufficient IMHO.
