drm/radeon: also try GART for CPU accessed buffers

2014-06-09T12:29:13+00:00

commit 544092596e8ac269f70e70961b5e9381909c9b1e upstream.

Placing them exclusively into VRAM might not work all the time.

Revert "drm/radeon: fix bo creation retry path"

2012-09-12T02:37:23+00:00

commit 676bc2e1e4f9072f7a640d5b7c99ffdf9709a6e7 upstream.

This reverts commit d1c7871ddb1f588b8eb35affd9ee1a3d5e11cd0c.

ttm_bo_init() destroys the BO on failure. So this patch makes
the retry path work with freed memory.  This ends up causing
kernel panics when this path is hit.

commit d1c7871ddb1f588b8eb35affd9ee1a3d5e11cd0c upstream.

leak.

drm/radeon: Restrict offset for legacy hardware cursor.

2012-04-02T16:52:47+00:00

commit c4353016dac10133fa5d8535af83f0c4845a2915 upstream.

The hardware only takes 27 bits for the offset, so larger offsets are
truncated, and the hardware cursor shows random bits other than the intended
ones.

Revert "drm/ttm: add a way to bo_wait for either the last read or last write"

2011-10-27T16:28:37+00:00

This reverts commit dfadbbdb57b3f2bb33e14f129a43047c6f0caefa.

Further upstream discussion between Marek and Thomas decided this wasn't
fully baked and needed further work, so revert it before it hits mainline.

drm/radeon: Move more code out of line

2011-10-18T08:53:05+00:00

With this patch I'm only about 50k larger with DRM debugging
enables (why is that enabled by default?!?), and slightly
smaller without.
