Only the generated configs baked in at build time were allowed. It quickly became obvious that we would need to allow applications to upload their own configurations, for instance to be able to test new ones, and so by the next stable version (4.14) we added uAPIs to allow uploading new configurations. When adding that capability, we took the opportunity to remove most HW configurations except the TestOa one which is a configuration IGT would rely on to verify that the HW is outputting correct values. At the time it made sense to have that confiuration in at the same time a given HW platform added to the i915-perf driver. Now that IGT has become the reference point for HW configurations (see commit 53f8f541ca ("lib: Add i915_perf library"), previously this was located in the GPUTop repository), the need for having those configurations in i915-perf is gone. On the Mesa side, we haven't relied on this test configuration for a while. The MDAPI library always required 4.14 feature level and always loaded its configuration into i915. I'm sure nobody will miss this generated stuff in i915 :) v2: Fix selftests by creating an empty config v3: Fix unlocking on allocation error (Dan Carpenter) v4: Fixup checkpatch warnings v5: Fix incorrect unlock in error path (Umesh) Signed-off-by: Lionel Landwerlin Reviewed-by: Umesh Nerlige Ramappa Link: https://patchwork.freedesktop.org/patch/msgid/20200317132222.2638719-1-lionel.g.landwerlin@intel.com --- drivers/gpu/drm/i915/Makefile | 17 --- drivers/gpu/drm/i915/i915_perf.c | 81 +------------- drivers/gpu/drm/i915/i915_perf_types.h | 2 -

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...

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. This for better clarity. v3: Rebased onto current drm-tip, as of 16-March-2020. Adapt to new edid_quirks parameter of drm_dp_has_quirk().

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 Signed-off-by: Ville Syrjälä Link: https://patchwork.freedesktop.org/patch/msgid/20200318174515.31637-1-ville.syrjala@linux.intel.com Reviewed-by: Rodrigo Vivi --- .../gpu/drm/i915/display/intel_atomic_plane.c | 21 +++++++++++++------ .../gpu/drm/i915/display/intel_atomic_plane.h | 2 ++ drivers/gpu/drm/i915/display/intel_display.c | 6 ++---- 3 files changed, 19 insertions(+), 10 deletions(-) diff --git a/drivers/gpu/drm/i915/display/intel_atomic_plane.c b/drivers/gpu/drm/i915/display/intel_atomic_plane.c index 457b258683d30..25dfeb3197aa9 100644 --- a/drivers/gpu/drm/i915/display/intel_atomic_plane.c +++ b/drivers/gpu/drm/i915/display/intel_atomic_plane.c @@ -264,6 +264,20 @@ void intel_plane_copy_uapi_to_hw_state(struct intel_plane_state *plane_state, plane_state->hw.color_range = from_plane_state->uapi.color_range; } +void intel_plane_set_invisible(struct intel_crtc_state *crtc_state, + struct intel_plane_state *plane_state) +{ + struct intel_plane *plane = to_intel_plane(plane_state->uapi.plane); + + crtc_state->active_planes &= ~BIT(plane->id); + crtc_state->nv12_planes &= ~BIT(plane->id); + crtc_state->c8_planes &= ~BIT(plane->id); + crtc_state->data_rate[plane->id] = 0; + crtc_state->min_cdclk[plane->id] = 0; + + plane_state->uapi.visible = false; +} + int intel_plane_atomic_check_with_state(const struct intel_crtc_state *old_crtc_state, struct intel_crtc_state *new_crtc_state, const struct intel_plane_state *old_plane_state, @@ -273,12 +287,7 @@ int intel_plane_atomic_check_with_state(const struct intel_crtc_state *old_crtc_ const struct drm_framebuffer *fb = new_plane_state->hw.fb; int ret; - new_crtc_state->active_planes &= ~BIT(plane->id); - new_crtc_state->nv12_planes &= ~BIT(plane->id); - new_crtc_state->c8_planes &= ~BIT(plane->id); - new_crtc_state->data_rate[plane->id] = 0; - new_crtc_state->min_cdclk[plane->id] = 0; - new_plane_state->uapi.visible = false; + intel_plane_set_invisible(new_crtc_state, new_plane_state); if (!new_plane_state->hw.crtc && !old_plane_state->hw.crtc) return 0; diff --git a/drivers/gpu/drm/i915/display/intel_atomic_plane.h b/drivers/gpu/drm/i915/display/intel_atomic_plane.h index a6bbf42bae1f1..59dd1fbb02eaa 100644 --- a/drivers/gpu/drm/i915/display/intel_atomic_plane.h +++ b/drivers/gpu/drm/i915/display/intel_atomic_plane.h @@ -52,5 +52,7 @@ int intel_plane_atomic_calc_changes(const struct intel_crtc_state *old_crtc_stat int intel_plane_calc_min_cdclk(struct intel_atomic_state *state, struct intel_plane *plane, bool *need_cdclk_calc); +void intel_plane_set_invisible(struct intel_crtc_state *crtc_state, + struct intel_plane_state *plane_state); #endif /* __INTEL_ATOMIC_PLANE_H__ */ diff --git a/drivers/gpu/drm/i915/display/intel_display.c b/drivers/gpu/drm/i915/display/intel_display.c index dd47eb65b5637..58e501ceca5ea 100644 --- a/drivers/gpu/drm/i915/display/intel_display.c +++ b/drivers/gpu/drm/i915/display/intel_display.c @@ -12377,10 +12377,8 @@ int intel_plane_atomic_calc_changes(const struct intel_crtc_state *old_crtc_stat * only combine the results from all planes in the current place? */ if (!is_crtc_enabled) { - plane_state->uapi.visible = visible = false; - crtc_state->active_planes &= ~BIT(plane->id); - crtc_state->data_rate[plane->id] = 0; - crtc_state->min_cdclk[plane->id] = 0; + intel_plane_set_invisible(crtc_state, plane_state); + visible = false; } if (!was_visible && !visible) From b412c63f1cba70b0e21927ae840aa45e024be97f Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Fri, 20 Mar 2020 13:01:56 +0000 Subject: [PATCH 036/202] drm/i915/gt: Report context-is-closed prior to pinning Our assertion caught that we do try to pin a closed context if userspace is viciously racing context-closure with execbuf, so make it fail gracefully.

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.

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.

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 Cc: Dhinakaran Pandiyan Cc: Ville Syrjälä Reviewed-by: Ville Syrjälä Signed-off-by: José Roberto de Souza Link: https://patchwork.freedesktop.org/patch/msgid/20200319211535.114625-1-jose.souza@intel.com --- drivers/gpu/drm/i915/display/intel_fbc.c | 54 +++++++++++++++++++++--- drivers/gpu/drm/i915/i915_drv.h | 1 + 2 files changed, 48 insertions(+), 7 deletions(-) diff --git a/drivers/gpu/drm/i915/display/intel_fbc.c b/drivers/gpu/drm/i915/display/intel_fbc.c index 02be14b693d4f..56bcd6c52a02c 100644 --- a/drivers/gpu/drm/i915/display/intel_fbc.c +++ b/drivers/gpu/drm/i915/display/intel_fbc.c @@ -608,6 +608,19 @@ static bool pixel_format_is_valid(struct drm_i915_private *dev_priv, } } +static bool rotation_is_valid(struct drm_i915_private *dev_priv, + u32 pixel_format, unsigned int rotation) +{ + if (INTEL_GEN(dev_priv) >= 9 && pixel_format == DRM_FORMAT_RGB565 && + drm_rotation_90_or_270(rotation)) + return false; + else if (INTEL_GEN(dev_priv) <= 4 && !IS_G4X(dev_priv) && + rotation != DRM_MODE_ROTATE_0) + return false; + + return true; +} + /* * For some reason, the hardware tracking starts looking at whatever we * programmed as the display plane base address register.

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.)

To be open to different usages make the new "intel_gt_debugfs_register_files()"[*] function more generic by converting the 'struct *gt' pointer to a 'void *' type. I take the chance to rename the functions by using "intel_gt_" as prefix instead of "debugfs_", so that "debugfs_gt_register_files()" becomes "intel_gt_debugfs_register_files()".

The rationale for this behavior is that HuC requires GuC for authentication and therefore is not supported by itself. However, we do not allow defining HuC fw wthout GuC fw and selecting HuC in modparam implicitly selects GuC as well, so we can't actually hit a scenario where HuC is selected alone. Therefore, we can flip the support check to reflect the HW capabilities and fw availability, which is more intuitive and will make it cleaner to log HuC the difference between not supported in HW and not selected. Removing the difference between GuC and HuC also allows us to simplify the init_early, since we don't need to differentiate the support based on the type of uC.

The guc_load_status debugfs has been squashed in the guc_info one, has having separate ones wasn't very useful. The HuC debugfs has been renamed huc_info to match. v2: keep printing HUC_STATUS2 (Tony), avoid const->non-const container_of (Jani) Suggested-by: Michal Wajdeczko Signed-off-by: Daniele Ceraolo Spurio Cc: Michal Wajdeczko Cc: John Harrison Cc: Matthew Brost Cc: Tony Ye Cc: Jani Nikula Reviewed-by: John Harrison Signed-off-by: Chris Wilson Link: https://patchwork.freedesktop.org/patch/msgid/20200326181121.16869-5-daniele.ceraolospurio@intel.com --- drivers/gpu/drm/i915/gt/uc/intel_guc.c | 44 +++++++ drivers/gpu/drm/i915/gt/uc/intel_guc.h | 2 + drivers/gpu/drm/i915/gt/uc/intel_guc_log.c | 92 +++++++++++++++ drivers/gpu/drm/i915/gt/uc/intel_guc_log.h | 4 + drivers/gpu/drm/i915/gt/uc/intel_huc.c | 29 +++++ drivers/gpu/drm/i915/gt/uc/intel_huc.h | 2 + drivers/gpu/drm/i915/i915_debugfs.c | 131 +++------------------ 7 files changed, 189 insertions(+), 115 deletions(-) diff --git a/drivers/gpu/drm/i915/gt/uc/intel_guc.c b/drivers/gpu/drm/i915/gt/uc/intel_guc.c index 827d75073879b..861657897c0f9 100644 --- a/drivers/gpu/drm/i915/gt/uc/intel_guc.c +++ b/drivers/gpu/drm/i915/gt/uc/intel_guc.c @@ -723,3 +723,47 @@ int intel_guc_allocate_and_map_vma(struct intel_guc *guc, u32 size, return 0;

A subfolder has been used to keep the same structure we have for the code. v2: use intel_* prefix (Jani), rebase on new gt_debugfs_register_files, fix permissions for writable debugfs files. v3: Rename files (Michal), remove blank line (Jani), fix sparse warns.

This changes introduce checks on the OA data written into the circular buffer to make as much data as possible available on the first iteration of the polling timer. v2: Use OA_TAKEN macro without the gtt_offset (Lionel) v3: (Umesh) - Rebase - Change report to report32 from below review https://patchwork.freedesktop.org/patch/330704/?series=66697&rev=1 v4: (Ashutosh, Lionel) - Fix checkpatch errors - Fix aging_timestamp initialization - Check for only one valid landed report - Fix check for unlanded report v5: (Ashutosh) - Fix bug in accurately determining landed report. - Optimize the check for landed reports by going as far as the previously determined aged tail.

This is used by audio driver when it resets the HDA controller. It seems explicit toggling of the wakeline can help to fix problems with probe failing on some gen12 platforms. And based on specs, there is no reason why this programming sequence should not be applied to all gen9+ platforms. No side-effects are seen on gen10/11. So apply the wake-logic to all gen9+ platforms.

However, we only revoke mmaps for GGTT bindings and we never allow userptr to create a GGTT binding so the warning should be false and is simply caused by our conflation of the aliasing-ppgtt with the ggtt. So lets try treating the binding into the aliasing-ppgtt as a separate lockclass from the ggtt. The downside is that we are deliberately suppressing lockdep;s ability to warn us of cycles.

We can achieve this by preventing the context from completing while we reload a new ELSP (by applying ring_set_paused(1) across the whole of dequeue), except this eventually fails due to a lite-restore into a waiting semaphore does not generate an ACK. Instead, we try to avoid making the GPU do anything too challenging and not submit a new ELSP while the interrupts + CSB events appear to have fallen behind the completed contexts. We expect it to catch up shortly so we queue another tasklet execution and hope for the best.

This is especially important as we now wait for the final oa_config setup to be completed and as this wait may be on a distinct context to the state modifications, we need that command packet to be always last in the queue. We borrow the i915_active for its ability to track multiple timelines and the last dma_fence on each; a flexible dma_resv. Keeping track of each dma_fence is important for us so that we can efficiently schedule the requests and reprioritise as required.

With luck, this has a secondary benefit of splitting the malloc size to within reason and avoid vmalloc. The downside is that we might require two separate vmallocs -- but much less likely. In the process, this prevents a memory leak on the ww_mutex error unwind.

Instead, we see the completion event of the currently active request [ff84:45155] but at the time of processing that event, the breadcrumb has not yet been written. Though by the time we do print out the debug info, the seqno write of ff84:45156 has landed! Therefore there is a serialisation problem between the seqno writes and CS events, not just between the CS buffer and its head/tail pointers as previously observed on Icelake. This is not a huge problem, as we don't strictly rely on the breadcrumb to determine HW activity, but it may indicate that interrupt delivery is before the seqno write, aka bringing back the plague of missed interrupts from yesteryear. However, there is no indication of this wider problem, so let's just flush the seqno read before reporting an error. If it persists after the fresh read we can worry again.

This has been superseded by being more proactive in removing objects we cannot shrink from the shrinker lists, and so we can drop the clumsy attempt at atomically counting the bind count and comparing it to the number of pinned mappings of the object. This will only get more clumsier with asynchronous binding and unbinding.

This reserve is expected to be only used for kernel contexts when barriers must be emitted [almost] without fail. The main consumer for this reserved request is expected to be engine-pm, for which we know that there will always be at least the previous pm request that we can reuse under mempressure (so there should always be a spare request for engine_park()). This is an alternative to using a comparatively bulky mempool, which requires custom handling for both our reserved allocation requirement and to protect our TYPESAFE_BY_RCU slab cache. The advantage of mempool would be that it would allow us to keep a larger per-engine request pool. However, converting over to mempool is straightforward should the need arise.

charset=UTF-8 Content-Transfer-Encoding: 8bit Transcoder port sync was introduced to the hardware in BDW. We can trivially enable it for SKL+ since the same codepaths are already used for ICL+ port sync. The only difference is the actual location of the bits we need to poke. We leave BDW out (at least for now) since it uses different modeset paths that haven't been adapted for port sync, and IIRC using the feature would involve some extra workarounds we've not implemented. Pre-BDW hardware does not support port sync so we'd have to tweak the modeset sequence to start the pipes as close together as possible and hope for the best. So far no one has seriously tried to implement that.

We can unmask that interrupt and so respond to a semaphore wait by yielding the timeslice, if we have another context to yield to! The only real complication is that the interrupt is only generated for the start of the semaphore wait, and is asynchronous to our process_csb() -- that is, we may not have registered the timeslice before we see the interrupt. To ensure we don't miss a potential semaphore blocking forward progress (e.g. selftests/live_timeslice_preempt) we mark the interrupt and apply it to the next timeslice regardless of whether it was active at the time. v2: We use semaphores in preempt-to-busy, within the timeslicing implementation itself! Ergo, when we do insert a preemption due to an expired timeslice, the new context may start with the missed semaphore flagged by the retired context and be yielded, ad infinitum. To avoid this, read the context id at the time of the semaphore interrupt and only yield if that context is still active.

The state save has proven to work well and it is needed in newer platforms, so needs to be extended. Although the logic is not in practise needed on GEN9/10 systems, follow the hardware specification and apply state and restore on all gen9+ platforms.
