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:

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:

Ville Syrjälä authored
We only consider crtc_state->enable when initially calculating plane visibility. Later on we try to override the plane's state to invisible if the crtc is in DPMS off state (crtc_state->active==false). Unfortunately the code doing that only updates the plane_state.visible flag and the crtc_state.active_planes bimask, but forgets to update some of the other plane bitmasks stored in the crtc_state. Namely crtc_state.nv12_planes is left set up based on the original visibility check which makes icl_check_nv12_planes() pick a slave plane for the flagged plane in the bitmask. Later on we hit the watermark code which sees a plane with a slave assigned and it then makes the logical assumption that the master plane must itself be visible. Since the master's plane_state.visible flag was already cleared we get a WARN. Fix the problem by clearing all the plane bitmasks for DPMS off. This is more or less the wrong approach and instead we should calculate all the plane related state purely based crtc_state->enable (to guarantee that the subsequent DPMS on can't fail). However in the past we definitely had some roadblocks to making that happen. Not sure how many are left these days, but let's stick to the current approach since it's a much simpler fix to the immediate problem (the WARN). v2: Keep the visible=false, it's important (Rodrigo) Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by:

This fixes a problem found on the MacBookPro 2017 Retina panel. The panel reports 10 bpc color depth in its EDID, and the firmware chooses link settings at boot which support enough bandwidth for 10 bpc (324000 kbit/sec = multiplier 0xc), but the DP_MAX_LINK_RATE dpcd register only reports 2.7 Gbps (multiplier value 0xa) as possible, in direct contradiction of what the firmware successfully set up. This restricts the panel to 8 bpc, not providing the full color depth of the panel. This patch adds a quirk specific to the MBP 2017 15" Retina panel to add the additiional 324000 kbps link rate during edp setup. Link to previous discussion of a different attempted fix with Ville and Jani: https://patchwork.kernel.org/patch/11325935/ v2: Follow Jani's proposal of defining quirk_rates[] instead of just appending 324000.

As we have already enabled supported infrastructure for non-contiguous pipe fusing in driver, we don't require non-contiguous pipe_mask check anymore. It is an unlike condition, it make sense to remove this condition. changes since RFC: - using intel_pipe_mask_is_valid() function to check integrity of pipe_mask. [Ville] v2: - simplify condition in intel_pipe_mask_is_valid(). [Ville] v3: - removed non-contiguous pipe fusing check.

On running several back to back perf capture sessions involving closing and opening the perf stream, invalid OA reports are seen in the beginning of the OA buffer in some sessions. Fix this by invalidating OA TLB when the perf stream is closed or disabled on gen12. Signed-off-by:

In order to better respond to new heartbeat intervals given via sysfs, always reprogramme an active heartbeat upon change (i.e. use mod_delayed_work to reschedule rather than queue_delayed_work which ignores an already active work.) Signed-off-by:

On Gen11 powergating half the execution units is a functional requirement when using the VME samplers. Not fullfilling this requirement can lead to hangs. This unfortunately plays fairly poorly with the NOA requirements. NOA requires a stable power configuration to maintain its configuration. As a result using OA (and NOA feeding into it) so far has required us to use a power configuration that can work for all contexts. The only power configuration fullfilling this is powergating half the execution units. This makes performance analysis for 3D workloads somewhat pointless. Failing to find a solution that would work for everybody, this change introduces a new i915-perf stream open parameter that punts the decision off to userspace. If this parameter is omitted, the existing Gen11 behavior remains (half EU array powergating). This change takes the initiative to move all perf related sseu configuration into i915_perf.c v2: Make parameter priviliged if different from default v3: Fix context modifying its sseu config while i915-perf is enabled v4: Always consider global sseu a privileged operation (Tvrtko) Override req_sseu point in intel_sseu_make_rpcs() (Tvrtko) Remove unrelated changes (Tvrtko) v5: Some typos (Tvrtko) Process sseu param in read_properties_unlocked() (Tvrtko) v6: Actually commit the bits from v5...
