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

2012-01-18T15:31:54+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

2012-01-18T15:31:54+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

2012-01-18T15:31:54+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.

drm/radeon/kms/atom: fix possible segfault in pm setup

commit 4376eee92e5a8332b470040e672ea99cd44c826a upstream.

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

2012-01-06T22:17:22+00:00

commit 77e00f2ea94abee1ad13bdfde19cf7aa25992b0e upstream.

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: fix DP setup on TRAVIS bridges

2011-12-21T20:58:32+00:00

commit cf2aff6eff251b6fbdaf8c253e65ff7c693de8cd upstream.

Supposedly both NUTMEG and TRAVIS should use the same
panel mode, but switching the panel mode for TRAVIS
gets things working.

commit 1d33e1fc8dcce667a70387b666a8b6f60153d90f upstream.

Return the encoder id rather than a boolean.  This is needed
for differentiate between multiple DP bridge chips.

reset happens while waiting for a page flip.
