Add a new macro, wait_for, to simplify the act of waiting on a register to change state. wait_for() takes three arguments, the condition to inspect on every loop, the maximum amount of time to wait and whether to yield the cpu for a length of time after each check. v2: Upgrade failure messages to DRM_ERROR on the suggestion of Eric Anholt. We do not expect to hit these conditions as they reflect programming errors, so if we do we want to be notified. Signed-off-by:

The cleanup path for early abort failed to nullify the gem_buffer. The likely consequence of this is zero, since a failure here should mean aborting the module load. Signed-off-by:

Previously, we only remembered to update the watermarks for i9xx, and incorrectly assumed that the crtc->enabled flag was valid at that point in the dpms cycle. Note that on my x201s this makes a SR bug on pipe 1 much easier to hit. (Since before this patch when disabling pipe 0, we either didn't update the watermarks at all, or when we did we still thought we had two pipes enabled and so disabled SR.)

shmfs doesn't actually implement i_ops->truncate() so we were not immedatiately releasing the backing pages when shrinking the gfx cache under OOM. Instead use a combination of truncate_inode_pages() and i_ops->truncate_range() as is used by shmem_delete_inode(). Signed-off-by:

Directly read the GTT mapping for the contents of the batch buffers rather than relying on possibly stale CPU caches. Also for completeness scan the flushing/inactive lists for the current buffers - we are collecting error state after all. Signed-off-by:

Chris Wilson authored
In order to reduce the penalty of fallbacks under memory pressure and to avoid a potential immediate ping-pong of evicting a mmaped buffer, we move the object to the tail of the inactive list when a page is freshly faulted or the object is moved into the CPU domain. We choose not to protect the CPU objects from casual eviction, preferring to keep the GPU active for as long as possible. v2: Daniel Vetter found a bug where I forgot that pinned objects are kept off the inactive list.

Based in a large part upon Daniel Vetter's implementation and adapted for handling multiple rings in a single pass. This should lead to better gtt usage and fixes the page-fault-of-doom triggered. The fairness is provided by scanning through the GTT space amalgamating space in rendering order. As soon as we have a contiguous space in the GTT large enough for the new object (and its alignment), evict any object which lies within that space. This should keep more objects resident in the GTT. Doing throughput testing on a PineView machine with cairo-perf-trace indicates that there is very little difference with the new LRU scan, perhaps a small improvement... Except oddly for the poppler trace.

The eviction code is the gnarly underbelly of memory management, and is clearer if kept separated from the normal domain management in GEM. Signed-off-by:

This will be used by the eviction logic to maintain fairness between the rings. Signed-off-by:

Daniel Vetter authored
This does two little changes: - Add an alignment parameter for evict_something. It's not really great to whack a carefully sized hole into the gtt with the wrong alignment. Especially since the fallback path is a full evict. - With the inactive scan stuff we need to evict more that one object, so move the unbind call into the helper function that scans for the object to be evicted, too. And adjust its name. No functional changes in this patch, just preparation. Signed-Off-by:

In order to properly track bound objects, they need to exist on one of the inactive/active lists or be pinned. As this is a requirement, do the work inside i915_gem_bind_to_gtt() rather than dotted around the callsites. Signed-off-by:

As we check that the ringbuffer will not wrap upon emission, we do not need to check that incrementing the tail wrapped every time. However, we do upon advancing just in case the tail is now pointing at the very end of the ring. Likewise we can account for the space used during emission in begin() and avoid decrementing it for every emit. Signed-off-by:

My i855GM suffers from a 80k/s interrupt storm without this. So add 2nd gen to the list of things that don't like more than one outstanding pageflip request. Furthermore I've changed the busy loop into a ringbuffer wait. Busy-loops that don't check whether the chip died are simply evil. And performance should actually improve, because there's usually a decent amount of rendering queued on the gpu, hopefully rendering that MI_WAIT into a noop by the time it's executed. The current code holds dev->struct_mutex while executing this loop, hence stalling all other gem activity anyway. Signed-off-by:
