We move the virtual breadcrumb from one physical engine to the next, if the next virtual request is scheduled on a new physical engine. Since the virtual context can only be in one signal queue, we need it to track the current physical engine for the new breadcrumbs. However, to move the list we need both breadcrumb locks -- and since we cannot take both at the same time (unless we are careful and always ensure consistent ordering) stage the movement of the signaler via the current virtual request.

If the caller allows and we do not have to wait for any signals, immediately execute the work within the caller's process. By doing so we avoid the overhead of scheduling a new task, and the latency in executing it, at the cost of pulling that work back into the immediate context. (Sometimes we still prefer to offload the task to another cpu, especially if we plan on executing many such tasks in parallel for this client.) Signed-off-by:

We dropped calling process_csb prior to handling direct submission in order to avoid the nesting of spinlocks and lift process_csb() and the majority of the tasklet out of irq-off. However, we do want to avoid ksoftirqd latency in the fast path, so try and pull the interrupt-bh local to direct submission if we can acquire the tasklet's lock. v2: Document the read of pending[0] from outside the tasklet with READ_ONCE.

Measure and compare the energy consumed, as reported by the rapl MSR, by the GPU while in RC0 and RC6 states. Throw an error if RC6 does not at least halve the energy consumption of RC0, as this more than likely means we failed to enter RC0 correctly. If we can't measure the energy draw with the MSR, then it will report 0 for both measurements. Since the measurement works on all gen6+, this seems worth flagging as an error. Signed-off-by:

We set the priority hint on execlists to avoid executing the tasklet for when we know that there will be no change in execution order. However, as we set it from the virtual engine for all siblings, but only one physical engine may respond, we leave the hint set on the others stopping direct submission that could take place. If we do not set the hint, we may attempt direct submission even if we don't expect to submit. If we set the hint, we may not do any submission until the tasklet is run (and sometimes we may park the engine before that has had a chance). Ergo there's only a minor ill-effect on mixed virtual/physical engine workloads where we may try and fail to do direct submission more often than required. (Pure virtual / engine workloads will have redundant tasklet execution suppressed as normal.) Closes: https://gitlab.freedesktop.org/drm/intel/issues/1522Signed-off-by:

dGFX has local memory so it does not have aperture or support CPU fences but even for iGFX it have a small number of fences. As replacement for fences to track frontbuffer modifications by CPU we have a software tracking that is already in used by FBC and PSR. PSR don't support fences so it shows that this tracking is reliable. So lets make fences a nice-to-have to activate FBC for GEN9+, this will allow us to enable FBC for dGFXs and iGFXs even when there is no available fence. We do not set fences to rotated planes but FBC only have restrictions against 16bpp, so adding it here. Also adding a new check for the tiling format, fences are only set to X and Y tiled planes but again FBC don't have any restrictions against tiling so adding linear as supported as well, other formats should be added after tested but IGT only supports drawing in thse 3 formats. intel_fbc_hw_tracking_covers_screen() maybe can also have the same treatment as fences but BSpec is not clear if the size limitation is for hardware tracking or general use of FBC and I don't have a 5K display to test it, so keeping as is for safety. v2: - Added tiling and pixel format rotation checks - Changed the GEN version not requiring fences to 11 from 9, DDX needs some changes but it don't have support for GEN11+ v3: - Changed back to GEN9+ - Moved GEN test to inside of tiling_is_valid() v4: - moved rotation check to its own functions v5: - renamed rotations_is_valid to rotation_is_valid - moved pre-g4x rotation check to rotation_is_valid() Cc: Daniel Vetter <daniel.vetter@intel.com> Cc: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by:

On Ivybridge, we can go lower than rc6 to rc6p. And this is required for Ivybridge to hit the same minimum power consumption as rc6 on other platforms, so make it so. v2: Update selftest to include all rc6 residency counters Note that Andi did mention that we should be converting the magic numbers into opaque magic macros, so if they ever get reused (unlikely given only Ivybridge used the extra modes) we'll need to pay back the technical debt.

It is strictly sufficient to only delay the intel_engine_pm_put from the context barrier (and not from the context exit) in order to prevent the gem_exec_nop contention. Adding the delay to the context exit incurs noticably extra penalty for soft-rc6.

It looks like some callers expect a non-volatile object, that they do not want the contents of the pages lost if they happen to not be looking at it. The shrinker however sees that we mark the pages as DONTNEED and believes that it can freely reap them. However, since the huge object use plain pages, they cannot be swapped out as they have no backing storge, and the only way we can shrink them is by discarding the contents. In light of the callers wanting to keep the contents around, both IS_SHRINKABLE and marking the pages as volatile are incorrect. If we drop the IS_SHRINKABLE flag we avoid the immediate issue of the shrinker accidentally removing valuable content. We will have to remember that a huge object is not suitable for exercising the shrinker interaction -- although we can introduce a shrinkable one if we require. Signed-off-by:

Keep the engine-pm awake until the next jiffie, to avoid immediate ping-pong under moderate load. (Forcing the idle barrier excerbates the moderate load, dramatically increasing the driver overhead.) On the other hand, delaying the idle-barrier slightly incurs longer rc6-off and so more power consumption. Closes: https://gitlab.freedesktop.org/drm/intel/issues/848Signed-off-by:

In some cases we want to hold onto the wakeref for a little after the last user so that we can avoid having to drop and then immediately reacquire it. Allow the last user to specify if they would like to keep the wakeref alive for a short hysteresis. v2: Embrace bitfield.h for adjustable flags. Signed-off-by:

As we store the handle lookup inside a radix tree, we do not need the gem_context->mutex except until we need to insert our lookup into the common radix tree. This takes a small bit of rearranging to ensure that the lut we insert into the tree is ready prior to actually inserting it (as soon as it is exposed via the radixtree, it is visible to any other submission). v2: For brownie points, remove the goto spaghetti. v3: Tighten up the closed-handle checks.

Abuse^W Take advantage that we know we are inside the GT wakeref and that prevents any client execbuf from reopening the i915_vma in order to claim all the vma to close without having to drop the spinlock to free each one individually. By keeping the spinlock, we do not have to restart if we run concurrently with i915_gem_free_objects -- which causes them both to restart continually and make very very slow progress.

Few edp panels like Sharp is triggering short and long hpd pulse after panel is getting powered off. Currently driver is already ignoring long pulse for eDP panel but in order to process the short pulse, it turns on the VDD which requires panel power_cycle_delay + panel_power_on_delay these delay on Sharp panel introduced the responsiveness overhead of 800ms in the modeset sequence and as well is in suspend sequence. Ignoring any short pulse if panel is powered off. FIXME: It requires to wait for panel_power_off delay in order to check the panel power status due to pps_lock because panel triggers short pulse immediately after writing PP_OFF to PP_CTRL register and wait_panel_off waits for panel_power_off delay with pps_lock held. This still creates responsiveness overhead of panel_power_off delay. v2: - checking vdd along with panel power to ignore the hpd. [Jani,Ville] v3: - safer side check to ignore the long hpd when eDP have power, adding type of hpd to debug log. [Jani] Signed-off-by:

If we park/unpark faster than we can respond to RPS events, we never will process a downclock event after expiring a waitboost, and thus we will forever restart the GPU at max clocks even if the workload switches and doesn't justify full power.
