This confuses our domain tracking and can (for gtt write domains) lead to a subsequent oops. Tested by tests/gem_exec_bad_domains from i-g-t. Reviewed-by:

With the error_state facility in place, this has outlived it's usefulness. It also oopses with the lates llc-reloc patches because it directly access objects through the gtt without any checks. Reviewed-by:

With the fence accounting fixed up in the previous commit not finding enough fences is a fatal error and userspace bug. Trashing the entire gtt is not gonna turn up that missing fence, so don't to this by returning another error thatn ENOSPC. This has the added benefit that it's easier to distinguish fence accounting errors from gtt space accounting issues. TTM serves as precendence for the EDEADLK error code - it returns it when the reservation code needs resources already blocked by the current reservation. Reviewed-by:

In order to correctly account for reserving space in the GTT and fences for a batch buffer, we need to independently track whether the fence is pinned due to a fenced GPU access in the batch or whether the buffer is pinned in the aperture. Currently we count the fenced as pinned if the buffer has already been seen in the execbuffer. This leads to a false accounting of available fence registers, causing frequent mass evictions. Worse, if coupled with the change to make i915_gem_object_get_fence() report EDADLK upon fence starvation, the batchbuffer can fail with only one fence required...

Based on a patch by Ben Widawsky, but with different colors for the bikeshed. In contrast to Ben's patch this one doesn't add the fault regs. Afaics they're for the optional page fault support which - we're not enabling - and which seems to be unsupported by the hw team. Recent bspec lacks tons of information about this that the public docs released half a year back still contain. Also dump ring HEAD/TAIL registers - I've recently seen a few error_state where just guessing these is not good enough. v2: Also dump INSTPM for every ring. v3: Fix a few really silly goof-ups spotted by Chris Wilson.

After the ILK vt-d workaround patches it became clear that we had introduced a bug. Chris Wilson tracked down the issue to recursive calls to unmap. This happens because we try to optimize waiting on requests by calling retire requests after the wait, which may drop the last reference on an object and end up freeing the object (and then unmap the object from the gtt). After the last patch we can now choose to defer processing the retire list. Kudos to Chris Wilson for tracking this one down. This patch fixes gem_unref_active_buffers from i-g-t. It was tested by forcing do_idle_maps to true. This also fixes tests/gem_linear_blits in intel-gpu-tools.

Sometimes it may be the case when we idle the gpu or wait on something we don't actually want to process the retiring list. This patch allows callers to choose the behavior. Reviewed-by:

Older specs claimed this was bit 11, but newer specs and the actual simulator code say it was bit 12. Regardless, we don't use MI_FLUSH, or try to enable it any more. Signed-off-by:

Eric Anholt authored
We have always been using the wrong bit -- it's bit 12. However, the bit also doesn't do anything -- hardware has always accepted the MI_FLUSH command even when it was specced not to. Given that there is only one MI_FLUSH emitted in all of the driver stack on gen6+ (in i965_video.c of the 2d driver, and it should be using other code to do its flush instead), just remove the MI_FLUSH enable instead of trying to fix it.

This patch enforces that the downclock clock source is the same as the preferred clock source for LVDS. This fixes a bug where the driver chooses a downclock clock source with a different P than the preferred mode clock source. This happened even if the preferred clock source implemented an acceptable rate for the downclock. The result of this bug is that downclock is disabled. Signed-off-by:
