2020-03-06drm/i915: Always propagate the invocation to i915_scheduleChris Wilson
We only call i915_schedule() when we know we have changed the priority on a request and so require to propagate any change in priority to its signalers (for PI). By unconditionally checking all of our signalers, we avoid skipping changes made prior to construction of the request (as the request may be waited upon before submission when used in parallel).

2020-03-06drm/i915: Add mechanism to submit a context WA on ring submissionMika Kuoppala
This patch adds framework to submit an arbitrary batchbuffer on each context switch to clear residual state for render engine on Gen7/7.5 devices. The idea of always emitting the context and vm setup around each request is primary to make reset recovery easy, and not require rewriting the ringbuffer. As each request would set up its own context, leaving it to the HW to notice and elide no-op context switches, we could restart the ring at any point, and reorder the requests freely. However, to avoid emitting clear_residuals() between consecutive requests in the ringbuffer of the same context, we do want to track the current context in the ring. In doing so, we need to be careful to only record a context switch when we are sure the next request will be emitted. This security mitigation change does not trigger any performance regression.

2020-03-05drm/i915: Don't check for wm changes until we've compute the wms fullyVille Syrjälä
Currently we're comparing the watermarks between the old and new states before we've fully computed the new watermarks. In particular skl_build_pipe_wm() will not account for the amount of ddb space we'll have. That information is only available during skl_compute_ddb() which will proceed to zero out any watermark level exceeding the ddb allocation. If we're short on ddb space this will end up adding the plane to the state due erronously determining that the watermarks have changed. Fix the problem by deferring skl_wm_add_affected_planes() until we have the final watermarks computed. Noticed this when trying enable transition watermarks on glk. We now computed the trans_wm as 28, but we only had 14 blocks of ddb, and thus skl_compute_ddb() ended up disabling the cursor trans_wm every time. Thus we ended up adding the cursor to every commit that didn't actually affect the cursor at all.

2020-03-05drm/i915: Don't check uv_wm in skl_plane_wm_equals()Ville Syrjälä
The hardware never sees the uv_wm values (apart from uv_wm.min_ddb_alloc affecting the ddb allocation). Thus there is no point in comparing uv_wm to determine if we need to reprogram the watermark registers. So let's check only the rgb/y watermark in skl_plane_wm_equals(). But let's leave a comment behind so that the next person reading this doesn't get as confused as I did when I added this check. If the ddb allocation ends up changing due to uv_wm skl_ddb_add_affected_planes() takes care of adding the plane to the state. TODO: we should perhaps just eliminate uv_wm from the state and simply track the min_ddb_alloc for uv instead.

2020-03-04drm/i915: Add invert-brightness quirk for Thundersoft TST178 tabletHans de Goede
The Thundersoft TST178 tablet uses a DSI panel with an external PWM controller (as all DSI panels do). But unlike other DSI panels a duty-cycle of 100% turns the backlight off and 0% sets it to maximum brightness. I've checked the VBT and there is a BDB_LVDS_BACKLIGHT section, but it does not set the active_low_pwm flag. This tablet re-uses the main PCI vendor and product ids for the subsystem ids, so I see no other option then to add a DMI based quirk to fix this. Note that the PWM backlight code in intel_panel.c currently does not honor the vbt.active_low_pwm flag, but that does not matter in this case.

However this test will also be true when DPLL4 on EHL is used since that shares the same DPLL ID (2). Add an extra check to ensure the PHY is actually a Type-C PHY before descending into the TBT handling. This should ensure EHL still takes the correct code path and somewhat future-proof the code as well. v2: Drop the gen+ check since only gen11+ platforms can have Type-C outputs.

According to Dell, trying to match their panels via OUI is not reliable enough and we've been told that we should check against the EDID instead. As well, Dell seems to have some panels that are actually intended to switch between using PWM for backlight controls and DPCD for backlight controls depending on whether or not the panel is in HDR or SDR mode. Yikes. Regardless, we need to add quirks for these so that DPCD backlight controls get enabled by default, since without additional driver support that's the only form of brightness control that will work. Hopefully in the future we can remove these quirks once we have a better way of probing for this.

The X1 Extreme is one of the systems that lies about which backlight interface that it uses in its VBIOS as PWM backlight controls don't work at all on this machine. It's possible that this panel could be one of the infamous ones that can switch between PWM mode and DPCD backlight control mode, but we haven't gotten any more details on this from Lenovo just yet. For the time being though, making sure the backlight 'just works' is a bit more important. So, add a quirk to force DPCD backlight controls on for these systems based on EDID (since this panel doesn't appear to fill in the device ID). Hopefully in the future we'll figure out a better way of probing this. Changes since v2: * The bugzilla URL is deprecated, bug reporting happens on gitlab now.

The whole point of using OUIs is so that we can recognize certain devices and potentially apply quirks for them. Normally this should work quite well, but there appears to be quite a number of laptop panels out there that will fill the OUI but not the device ID. As such, for devices like this I can't imagine it's a very good idea to try relying on OUIs for applying quirks. As well, some laptop vendors have confirmed to us that their panels have this exact issue. So, let's introduce the ability to apply DP quirks based on EDID identification.

For our convenience, and to avoid frequent allocations, we placed some lists we use for execbuf inside the common i915_vma struct. As we look to parallelise execbuf, such fields guarded by the struct_mutex BKL must be pulled under local control. Instead of using the i915_vma as our primary means of tracking the user's list of objects and their virtual mappings, we use a local eb_vma with the same lists as before (just now local not global). This should allow us to only perform the lookup of vma used for execution once during the execbuf ioctl, as currently we need to remove our secrets from inside i915_vma everytime we drop the struct_mutex as another execbuf may use the shared locations. Once potential user visible consequence is that we can remove the requirement that the execobj[] be unique, and only require that they do not conflict (i.e. you cannot softpin the same object into two locations.

2020-03-03drm/i915/gen11: Moving WAs to rcs_engine_wa_init()José Roberto de Souza
This are register of render engine, so after a render reset those would return to the default value and init_clock_gating() is not called for single engine reset. So here moving it rcs_engine_wa_init() that will guarantee that this WAs will not be lost.

2020-03-03drm/i915/gt: Drop the timeline->mutex as we wait for retirementChris Wilson
As we have pinned the timeline (using tl->active_count), we can safely drop the tl->mutex as we wait for what we believe to be the final request on that timeline. This is useful for ensuring that we do not block the engine heartbeat by hogging the kernel_context's timeline on a dead GPU.

2020-03-03drm/i915: Polish CHV .load_luts() a bitVille Syrjälä
It irks me to use crtc_state_is_legacy_gamma() inside the guts of the CHV color management code. Let's get rid of it and instead just consult cgm_mode to figure out if we want to enable the pipe gamma or the CGM gamma. Also CHV display engine is based on i965/g4x so we should fall back to the i965 path when the CGM gamma is not used.
