2025-02-11drm/i915: Fix CONFIG_DRM_I915_DEBUG_RUNTIME_PM=n buildVille Syrjälä
Looks like I missed one of myriad CONFIG_DRM_I915_DEBUG_RUNTIME_PM=n special cases when converting the intel_display_power_{get,put}() code to use struct intel_display.

The top of stolen memory is WOPCM, which shouldn't be accessed. Remove this portion from the stolen memory region for discrete platforms. This was already done for integrated, but was missing for discrete platforms.

2025-02-10drm/xe/pf: Use an explicit check to see if the device has LMTTPiotr Piórkowski
So far, the main condition for using LMTT has been to check that the device is a discrete gfx. Let's add a dedicated function to check if the device supports LMTT as not all future discrete GPU platforms will require LMTT. v2: - use xe_has_device_lmtt only when necessary - leave IS_DGFX for other things related to LMEM provisioning v3: - remove IS_SRIOV_PF condition from xe_device_has_lmtt (Michal Wajdeczko) - keep IS_SRIOV_PF asserts in LMTT-related code (Michal Wajdeczko) v4: - update commit description Signed-off-by: Piotr Piórkowski <piotr.piorkowski@intel.com> Cc: Michal Wajdeczko <michal.wajdeczko@intel.com> Cc: Michał Winiarski <michal.winiarski@intel.com> Cc: Satyanarayana K V P <satyanarayana.k.v.p@intel.com> Reviewed-by: Tejas Upadhyay <tejas.upadhyay@intel.com> Reviewed-by: Satyanarayana K V P <satyanarayana.k.v.p@intel.com> Signed-off-by: Michal Wajdeczko <michal.wajdeczko@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20250207113111.853821-2-piotr.piorkowski@intel.com

2025-02-07drm/xe: Enable SR-IOV for PTLMichal Wajdeczko
We should now have sufficient changes in the driver to run it on PTL platforms in the SR-IOV Physical Function (PF) mode, that would allow us to enable SR-IOV Virtual Functions (VFs), and successfully probe our driver in the VF mode on enabled VF devices. To unblock SR-IOV PF mode you need to load xe with modparam: xe.max_vfs=7 Then to enable VFs it is sufficient to use: $ echo 7 > /sys/bus/pci/devices/0000:00:02.0/sriov_numvfs Note that in default auto-provisioning all VFs are allocated with some amount of shared resources (like unlimited GPU execution and preemption times, fair GGTT space, fair GuC context IDs range, ...) However with CONFIG_DEBUG_FS enabled it is possible to tweak most of the SR-IOV configuration parameters using attributes like: /sys/kernel/debug/dri/0000:00:02.0/gt0/ ├── pf │   ├── contexts_spare │   ├── doorbells_spare │   ├── exec_quantum_ms │   ├── ggtt_spare │   ├── preempt_timeout_us │   ├── sched_priority │   └── ... ├── vf1 │   ├── contexts_quota │   ├── doorbells_quota │   ├── exec_quantum_ms │   ├── ggtt_quota │   ├── preempt_timeout_us │   ├── sched_priority │   └── ... ├── vf2 │   └── ... : Signed-off-by: Michal Wajdeczko <michal.wajdeczko@intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Cc: Lucas De Marchi <lucas.demarchi@intel.com> Cc: Thomas Hellstrom <thomas.hellstrom@linux.intel.com> Acked-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Reviewed-by: Jakub Kolakowski <jakub1.kolakowski@intel.com> Tested-by: Marcin Bernatowicz <marcin.bernatowicz@linux.intel.com> Reviewed-by: Marcin Bernatowicz <marcin.bernatowicz@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20250206214545.940-1-michal.wajdeczko@intel.com
2025-02-07drm/panic: Better binary encoding in QR codeJocelyn Falempe
The current encoding, is done by converting 13bits of input into 4 decimal digits, that are then encoded efficiently using the numeric encoding of the QR code specification. The Fido v2.2 specification [1] uses a similar approach for its QR-initiated authentication. The only difference is that it converts 7 bytes (56bits) of input into 17 decimal digits. The benefit is that the algorithm doesn't require to split input bytes into 13bits chunk, and the ratio is a bit better. This improvement was proposed by Jó Ágila Bitsch in [2]. drm_panic is still young, and the QR code feature is not widely used, so it's still time to switch to a common algorithm, shared with a widely used standard. I also changed the name of the url parameter, from zl= to z=, so the website can keep backward compatibility if needed.
