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

2012-01-26T01:24:35+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: add some loop timeouts in pageflip code

2011-12-09T16:52:38+00:00

commit f64964796dedca340608fb1075ab6baad5625851 upstream.

Avoid infinite loops waiting for surface updates if a GPU
reset happens while waiting for a page flip.

drm/radeon/kms: set HPD polarity in hpd_init()

2011-11-11T17:36:56+00:00

commit 64912e997f0fe13512e4c7b90e4f7c11cb922ab5 upstream.

Polarity needs to be set accordingly to connector status (connected
or disconnected). Set it up in hpd_init() so first hotplug works
reliably no matter what is the initial set of connector. hpd_init()
also covers resume so HPD will work correctly after resume as well.

drm/radeon/kms: use correct BUS_CNTL reg on rs600

BUS_CNTL is at 0x30 on rs600, not 0x4c.

drm/radeon/kms: pageflipping cleanup for avivo+

2011-04-04T00:08:35+00:00

Avoid touching the flip setup regs while
acceleration is running.  Set them at modeset
rather than during pageflip.  Touching these
regs while acceleration is active caused hangs
on pre-avivo chips.  These chips do not seem
to be affected, but better safe than sorry,
plus it avoids repeatedly reprogramming the
regs every flip.

drm/radeon: fix problem with changing active VRAM size. (v2)

2011-03-14T02:51:04+00:00

So we used to use lpfn directly to restrict VRAM when we couldn't
access the unmappable area, however this was removed in
93225b0d7bc030f4a93165347a65893685822d70 as it also restricted
the gtt placements. However it was only later noticed that this
broke on some hw.

This removes the active_vram_size, and just explicitly sets it
when it changes, TTM/drm_mm will always use the real_vram_size,
and the active vram size will change the TTM size used for lpfn
setting.

We should re-work the fpfn/lpfn to per-placement at some point
I suspect, but that is too late for this kernel.

Hopefully this addresses:

v2: fix reported useful VRAM size to userspace to be correct.

drm/radeon/kms: balance asic_reset functions

2011-01-17T02:21:57+00:00

First, we were calling mc_stop() at the top of the function
which turns off all MC (memory controller) clients,
then checking if the GPU is idle.  If it was idle we
returned without re-enabling the MC clients which would
lead to a blank screen, etc.  This patch checks if the
GPU is idle before calling mc_stop().

Second, if the reset failed, we were returning without
re-enabling the MC clients.  This patch re-enables
the MC clients before returning regardless of whether
the reset was successful or not.
