2024-08-16drm/xe: Add debugfs to dump GuC's hwconfigMatt Roper
Although the query uapi is the official way to get at the GuC's hwconfig table contents, it's still useful to have a quick debugfs interface to dump the table in a human-readable format while debugging the driver.

2024-08-16drm/xe/uc: Use managed bo for HuC and GSC objectsDaniele Ceraolo Spurio
Drmm actions are not the right ones to clean up BOs and we should use devm instead. However, we can also instead just allocate the objects using the managed_bo function, which will internally register the correct cleanup call and therefore allows us to simplify the code. While at it, switch to drmm_kzalloc for the GSC proxy allocation to further simplify the cleanup.

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. New description for the parameters: disable_display:Disable display (default: false) (bool) probe_display:Probe display HW, otherwise it's left untouched (default: true) (bool) Reviewed-by: Matt Roper <matthew.d.roper@intel.com> Acked-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240813141931.3141395-1-lucas.demarchi@intel.com Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com>

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.

2024-08-09drm/mgag200: vga-bmc: Control BMC scanout from encoderThomas Zimmermann
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.

Control the VIDRST pin from the VGA-BMC encoder's atomic_check and remove the respective code from CRTC. Makes the VIDRST functionality fully composable. The VIDRST pin allows an external clock source to control the SYNC signals of the Matrox chip. The functionality is part of the CRTC, but depends on the presence of the clock source. This is the case for some BMCs, so control the pin from the VGA-BMC output.

2024-08-09drm/mgag200: vga-bmc: Transparently handle BMCThomas Zimmermann
The VGA-BMC connector selects the VGA output if a display has been attached to the physical connector. Otherwise it selects the BMC output. In any case, the connector status is set to 'detected', so that the userspace compositor displays to it. Depending on the setting, the connector's display modes either come from the VGA monitor's EDID or from an internal list of BMC-compatible modes.

2024-08-08drm/xe: fix WA 14018094691Daniele Ceraolo Spurio
This WA is applied while initializing the media GT, but it a primary GT WA (because it modifies a register on the primary GT), so the XE_WA macro is returning false even when the WA should be applied. Fix this by using the primary GT in the macro. Note that this WA only applies to PXP and we don't yet support that in Xe, so there are no negative effects to this bug, which is why we didn't see any errors in testing. v2: use the primary GT in the macro instead of marking the WA as platform-wide (Lucas, Matt).

2024-08-08drm/i915: remove __i915_printk()Jani Nikula
With the previous cleanups, the last remaining user of __i915_printk() is i915_probe_error(). Switch that to use drm_dbg() and drm_err() instead, dropping the request to report bugs in the few remaining specific cases. It's not common for drivers to log bug filing requests to begin with, but these cases are in init, which is most likely to be tested in CI and least likely to be hit by end users anyway.

i915_report_error() presently acts as a wrapper for __i915_printk(). In practice, it would be better to use drm level error reporting wherever possible, so replace all uses of i915_report_error() with the equivalent drm_err() call. These cases are not worth having a dedicated wrapper to also print bug reporting info. Replacing the calls leaves i915_report_error() with no users, so remove it.
