2008-01-17[i915] Fix driver from cliprects changes, and clean up state emission.Eric Anholt
The fix for pageflipping with cliprects ended up causing a batch flush at an inopportune time, which is fixed by moving it up. Additionally, the recovery code for handling batch wraps at bad times is replaced by just checking for the space up front, and using a no_batch_wrap assert like on 965 to make sure that we weren't wrong about how much space that was.
2008-01-10[intel] Only flush batch when changing draw buffers, not every cliprect update.Eric Anholt
The previous code would reference freed memory on window moves.
2008-01-10[intel] Add more cliprect modes to cover other meanings for batch emits.Eric Anholt
The previous change gave us only two modes, one which looped over the batch per cliprect (3d drawing) and one that didn't (state updeast). However, we really want 4: - Batch doesn't care about cliprects (state updates) - Batch needs DRAWING_RECTANGLE looping per cliprect (3d drawing) - Batch needs to be executed just once (region fills, copies, etc.) - Batch already includes cliprect handling, and must be flushed by unlock time (copybuffers, clears). All callers should now be fixed to use one of these states for any batchbuffer emits. Thanks to Keith Whitwell for pointing out the failure.
2008-01-09[intel] Clean up cliprect handling in intel drivers.Eric Anholt
In particular, batch buffers are no longer flushed when switching from CLIPRECTS to NO_CLIPRECTS or vice versa, and 965 just uses DRM cliprect handling for primitives instead of trying to sneak in its own to avoid the DRM stuff. The disadvantage is that we will re-execute state updates per cliprect, but the advantage is that we will be able to accumulate larger batch buffers, which were proving to be a major overhead.
2007-12-07[965] Convert the driver to dri_bufmgr interface and enable TTM.Eric Anholt
This is currently believed to work but be a significant performance loss. Performance recovery should be soon to follow. The dri_bo_fake_disable_backing_store() call was added to allow backing store disable like bufmgr_fake.c did, which is a significant performance win (though it's missing the no-fence-subdata part). This commit is a squash merge of the 965-ttm branch, which had some history I wanted to avoid pulling due to noisiness and brokenness at many points for git-bisecting.

This could lead to incorrect rendering or even lockups.

2007-09-27Revert "WIP 965 conversion to dri_bufmgr."Eric Anholt
This reverts commit b2f1aa2389473ed09170713301b042661d70a48e. Somehow I ended up with my branch's save-this-while-I-work-on-master commit actually on master.
