Provide runtime asserts and tracking of i915_active via debugobjects. For example, this should allow us to check that the i915_active is only active when we expect it to be and is never freed too early. One consequence is that, for simplicity, we no longer allow i915_active to be on-stack which only affected the selftests. Signed-off-by:

i915_gem_wait_for_idle() and i915_retire_requests() introduce a dependency on the timeline->mutex. This is problematic as we want to later perform allocations underneath i915_active.mutex, forming a link between the shrinker, the timeline and active mutexes. Nip this cycle in the bud by removing the acquisition of the timeline mutex (i.e. retiring) from inside the shrinker. Signed-off-by:

There is a very small chance of triggering a log flush event when enabling or disabling CT buffers. Events triggered while CT buffers are disabled are logged in the SCRATCH_15 register using the same bits used in the CT message payload. Since our communication channel with GuC is turned off, we can save the message and handle it after we turn it back on. GuC should be idle and not generate more events in the meantime because we're not talking to it. v2: clear the mmio register on stop_communication as well (Chris) Signed-off-by:

Make sure we always have CT buffers enabled when the interrupts are enabled, so we can always handle interrupts from GuC. Also move the setting of the guc->send and guc->handler functions to the GuC communication control functions for consistency. The reorder also fixes the onion unwinding of intel_uc_init_hw, because guc_enable_communication would've left interrupts enabled when failing to enable CTB. v2: always retunr the result of ctch_enable() in intel_guc_ct_enable() (Michal) Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=110943Signed-off-by:Matthew Brost <matthew.brost@intel.com> Reviewed-by:

Since the anonymous i915_gt became struct intel_gt and encloses struct i915_gt_timelines, rename i915_gt_timelines to intel_gt_timelines to match its parentage. Signed-off-by:

Scratch vma lives under gt but the API used to work on i915. Make this consistent by renaming the function to intel_gt_scratch_offset and make it take struct intel_gt. v2: * Move to intel_gt. (Chris) Signed-off-by:

Our timelines are stored inside intel_gt so we can convert the interface to take exactly that and not i915. At the same time re-order the params to our more typical layout and replace the backpointer to the new containing structure. Signed-off-by:

For gt related operations it makes more logical sense to stay in the realm of gt instead of dereferencing via driver i915. This patch handles a few of the easy ones with work requiring more refactoring still outstanding. Signed-off-by:

Having introduced struct intel_gt (named the anonymous structure in i915) we can start using it to compartmentalize our code better. It makes more sense logically to have the code internally like this and it will also help with future split between gt and display in i915. v2: * Keep ggtt flush before fb obj flush. (Chris) v3: * Fix refactoring fail. * Always flush ggtt writes. (Chris) Signed-off-by:
