2024-08-17drm/xe/hw_engine_group: Ensure safe transition between execution modesFrancois Dugast
Provide a way to safely transition execution modes of the hw engine group ahead of the actual execution. When necessary, either wait for running jobs to complete or preempt them, thus ensuring mutual exclusion between execution modes. Unlike a mutex, the rw_semaphore used in this context allows multiple submissions in the same mode. v2: Use lockdep_assert_held_write, add annotations (Matt Brost) v3: Fix kernel doc, remove redundant code (Matt Brost) v4: Now that xe_hw_engine_group_suspend_faulting_lr_jobs can fail, propagate the error to the caller (Matt Brost) Signed-off-by: Francois Dugast <francois.dugast@intel.com> Reviewed-by: Matthew Brost <matthew.brost@intel.com> Signed-off-by: Matthew Brost <matthew.brost@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240809155156.1955925-9-francois.dugast@intel.com

2024-08-17drm/xe/hw_engine_group: Introduce xe_hw_engine_groupFrancois Dugast
A xe_hw_engine_group is a group of hw engines. Two hw engines belong to the same xe_hw_engine_group if one hw engine cannot make progress while the other is stuck on a page fault. Typically, hw engines of the same group share some resources such as EUs, but this really depends on the hardware configuration of the platforms. The simple engines partitioning proposed here might be too conservative but is intended to work for existing platforms. It can be optimized later if more sets of independent engines are identified. The hw engine groups are intended to be used in the context of faulting long-running jobs submissions. v2: Move to own files, improve error handling (Matt Brost) v3: Fix build issue reported by CI, improve commit message (Matt Roper) v4: Fix kernel doc v5: Add switch case for XE_ENGINE_CLASS_OTHER Signed-off-by: Francois Dugast <francois.dugast@intel.com> Reviewed-by: Matthew Brost <matthew.brost@intel.com> Signed-off-by: Matthew Brost <matthew.brost@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240809155156.1955925-2-francois.dugast@intel.com

2024-08-16drm/xe/mcr: Try to derive dss_per_grp from hwconfig attributesMatt Roper
When steering MCR register ranges of type "DSS," the group_id and instance_id values are calculated by dividing the DSS pool according to the size of a gslice or cslice, depending on the platform. These values haven't changed much on past platforms, so we've been able to hardcode the proper divisor so far. However the layout may not be so fixed on future platforms so the proper, future-proof way to determine this is by using some of the attributes from the GuC's hwconfig table. The hwconfig has two attributes reflecting the architectural maximum slice and subslice counts (i.e., before any fusing is considered) that can be used for the purposes of calculating MCR steering targets. If the hwconfig is lacking the necessary values (which should only be possible on older platforms before these attributes were added), we can still fall back to the old hardcoded values. Going forward the hwconfig is expected to always provide the information we need on newer platforms, and any failure to do so will be considered a bug in the firmware that will prevent us from switching to the buggy firmware release. It's worth noting that over time GuC's hwconfig has provided a couple different keys with similar-sounding descriptions. For our purposes here, we only trust the newer key "70" which has supplanted the similarly-named key "2" that existed on older platforms.

2024-08-14drm/xe: Move enable host l2 VRAM post MCR initTejas Upadhyay
xe_gt_enable_host_l2_vram() is reading the XE2_GAMREQSTRM_CTRL register that is currently missing the MCR annotation. However, just adding the annotation doesn't work as this function is called before MCR handling is initialized in xe_gt_mcr_init(). xe_gt_enable_host_l2_vram() is used to implement WA 16023588340 that needs to be done as early as possible during initialization in order to be effective since the MMIO writes impact it. In the failure scenario, driver would simply not be able to bind successfully. Moving xe_gt_enable_host_l2_vram() later, after MCR initialization is done, only incurs a few additional HW accesses, particularly when loading GuC for hwconfig. Binding/unbinding the driver 100 times in BMG still works so it should be ok to start handling the WA a little bit later. This is sufficient to allow adding the MCR annotation to XE2_GAMREQSTRM_CTRL.

2024-08-13drm/xe: Rename enable_display module paramLucas De Marchi
The different approach used by xe regarding the initialization of display HW has been proved a great addition for early driver bring up: core xe can be tested without having all the bits sorted out on the display side. On the other hand, the approach exposed by i915-display is to *actively* disable the display by programming it if needed, i.e. if it was left enabled by firmware. It also has its use to make sure the HW is actually disabled and not wasting power. However having both the way it is in xe doesn't expose a good interface wrt module params. From modinfo: disable_display:Disable display (default: false) (bool) enable_display:Enable display (bool) Rename enable_display to probe_display to try to convey the message that the HW is being touched and improve the module param description. To avoid confusion, the enable_display is renamed everywhere, not only in the module param.

2024-08-13drm/xe: Name and document Wa_14019789679Matt Roper
Early in the development of Xe we identified an issue with SVG state handling on DG2 and MTL (and later on Xe2 as well). In commit 72ac304769dd ("drm/xe: Emit SVG state on RCS during driver load on DG2 and MTL") and commit fb24b858a20d ("drm/xe/xe2: Update SVG state handling") we implemented our own workaround to prevent SVG state from leaking from context A to context B in cases where context B never issues a specific state setting. The hardware teams have now created official workaround Wa_14019789679 to cover this issue. The workaround description only requires emitting 3DSTATE_MESH_CONTROL, since they believe that's the only SVG instruction that would potentially remain unset by a context B, but still cause notable issues if unwanted values were inherited from context A. However since we already have a more extensive implementation that emits the entire SVG state and prevents _any_ SVG state from unintentionally leaking, we'll stick with our existing implementation just to be safe.

2024-08-09drm/xe: Move VM dma-resv lock from xe_exec_queue_create to __xe_exec_queue_initMatthew Brost
The critical section which requires the VM dma-resv is the call xe_lrc_create in __xe_exec_queue_init. Move this lock to __xe_exec_queue_init holding it just around xe_lrc_create. Not only is good practice, this also fixes a locking double of the VM dma-resv in the error paths of __xe_exec_queue_init as xe_lrc_put tries to acquire this too resulting in a deadlock.

2024-08-09drm/xe/pf: Fix VF config validation on multi-GT platformsMichal Wajdeczko
When validating VF config on the media GT, we may wrongly report that VF is already partially configured on it, as we consider GGTT and LMEM provisioning done on the primary GT (since both GGTT and LMEM are tile-level resources, not a GT-level). This will cause skipping a VF auto-provisioning on the media-GT and in result will block a VF from successfully initialize that GT. Fix that by considering GGTT and LMEM configurations only when checking if a VF provisioning is complete, and omit GGTT and LMEM when reporting empty/partial provisioning.

2024-08-09drm/mgag200: Remove BMC outputThomas Zimmermann
Mgag200's BMC connector tracks the status of an underlying physical connector and updates the BMC status accordingly. This functionality works around GNOME's settings app, which cannot handle multiple outputs on the same CRTC. The workaround is now obsolete as the VGA-BMC connector handles BMC support internally. Hence, remove the driver's code and the BMC output entirely.

Move calls to stop and start BMC scanout from CRTC helpers to the VGA-BMC encoder's atomic_disable and atomic_enable. Makes the BMC scanout transparent to the CRTC. DRM's atomic helpers call an encoder's atomic_disable and atomic_enable helpers for all enabled encoders. The BMC stops scanning out the VGA signal if modeset disables the VGA encoder, and starts scanning out if the modeset enables the VGA encoder.
