Propagate the timeout on transferring the fw back to the caller where it may act upon it, usually by restarting the xfer before failing. v2: Simplify the wait to only wait upon the guc signaling completion, with an assertion that the fw xfer must have completed for it to be ready!

Let's run through the entire plane check even when the plane is invisible due to zero constant alpha. This makes for more consistent behaviour since we check the src/dst coordinates, stride etc. against the hardware limits. Signed-off-by:

The SKL+ NV12 src width alignment w/a is still living in an odd place. Everything else was already relocated closer to the main plane check function. Move this workaround as well. As a bonus we avoid the funky rotated vs. not mess with the src coordinates as this now gets checked before we rotate the coordinates. Signed-off-by:

The way our hardware is designed doesn't seem to let us use the MI_RECORD_PERF_COUNT command without setting up a circular buffer. In the case where the user didn't request OA reports to be available through the i915 perf stream, we can set the OA buffer to the minimum size to avoid consuming memory which won't be used by the driver. v2: Simplify oa buffer size exponent selection (Chris) Reuse vma size field (Lionel) v3: Restrict size opening parameter to values supported by HW (Chris) v4: Drop out of date comment (Matt) Add debug message when buffer size is rejected (Matt) Signed-off-by:Lionel Landwerlin <lionel.g.landwerlin@intel.com> Reviewed-by:

A collection of very small cleanups/improvements around doorbell checking that do not deserve their own patch: - Move doorbell-related HW defs to intel_guc_reg.h - use GUC_NUM_DOORBELLS instead of GUC_DOORBELL_INVALID where appropriate - do not stop on error in guc_verify_doorbells - do not print drbreg on error: the only content of the register apart from the valid bit is the lower part of the physical memory address, which we can't use even if valid because we don't know which descriptor it came from (since the doorbell is in an unexpected state) - Move the checking of doorbell valid bit to a common helper. v2: add more cleanups (move defs, use GUC_NUM_DOORBELLS, don't stop in guc_verify_doorbells) (Michal) v3: move more things to intel_guc_reg, redefine GUC_DOORBELL_INVALID (Michal), drop guc_doorbell_qw since it just duplicates guc_doorbell_info Cc: Michal Wajdeczko <michal.wajdeczko@intel.com> Signed-off-by: -

Just sorting this "if" block from newer to older platform. The main difference here is the addition of a missing case with return false that should never occur. And if it occurs it is better than to raise a warn than use the icl one. The gen >= 11 was already present in the previous logic, although hidden. So, in summary no real functional change.

We wrongly assumed that GuC is only using last scratch register for G2H messages, but in fact it is also using register [14] to report sleep state status. Remove that register from our H2G send registers pool. v2: No message from host to GuC uses more than 8 registers and the GuC FW itself uses an 8-element array to store the H2G message, so we may reduce our send array to just 8 registers (Daniele) v3: use explicit define (Daniele) v4: and explicit comment (Daniele) Signed-off-by:

Replace the kvmalloc_array() with i915_gem_object_get_dma_address() when populating rotated vmas. One random access mechanism ought to be enough for everyone? To calculate the size of the radix tree I think we can do something like this (assuming 64bit pointers): num_pages = obj_size / 4096 tree_height = ceil(log64(num_pages)) num_nodes = sum(64^n, n, 0, tree_height-1) tree_size = num_nodes * 576 If we compare that with the object size we should get a relative overhead of around .2% to 1% for reasonable sized objects, which framebuffers tend to be.

The test requires driver tweaks to avoid causing error messages on intentionally-triggered errors and to stop accessing non existing register. However, this is a pure GuC FW interface test and should be covered by FW validation, so it isn't really worth tweaking the driver for it and we're better off dropping it instead. Testing the driver running out of doorbells is already covered by igt_guc_doorbells Suggested-by:
