Let's run through the entire plane check even when the plane is invisible due to zero constant alpha.

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.

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.

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: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Reviewed-by: Michal Wajdeczko <michal.wajdeczko@intel.com> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Link: https://patchwork.freedesktop.org/patch/msgid/20181022230427.5616-3-daniele.ceraolospurio@intel.com

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.

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.
