1537ec85 - drm/xe/uapi: Introduce API for EU stall sampling

Wed, 26 Feb 2025 01:47:06 +0000

drm/xe/uapi: Introduce API for EU stall samplingA new hardware feature first introduced in PVC gives capability toperiodically sample EU stall state and record counts for different stallreasons, on a per IP basis, aggregate across all EUs in a subslice andrecord the samples in a buffer in each subslice. Eventually, the aggregateddata is written out to a buffer in the memory. This feature is alsosupported in XE2 and later architecture GPUs.Use an existing IOCTL - DRM_IOCTL_XE_OBSERVATION as the interface into thedriver from the user space to do initial setup and obtain a file descriptorfor the EU stall data stream. Input parameter to the IOCTL is a structdrm_xe_observation_param in which observation_type should be set toDRM_XE_OBSERVATION_TYPE_EU_STALL, observation_op should beDRM_XE_OBSERVATION_OP_STREAM_OPEN and param should point to a chain ofdrm_xe_ext_set_property structures in which each structure has a pair ofproperty and value. The EU stall sampling input properties are defined indrm_xe_eu_stall_property_id enum.With the file descriptor obtained from DRM_IOCTL_XE_OBSERVATION, user spacecan enable and disable EU stall sampling with the IOCTLs:DRM_XE_OBSERVATION_IOCTL_ENABLE and DRM_XE_OBSERVATION_IOCTL_DISABLE.User space can also call poll() to check for availability of data in thebuffer. The data can be read with read(). Finally, the file descriptorcan be closed with close().v11: Changed a couple of variables in struct eu_stall_open_properties from unsigned int to int.v10: Use extension number while parsing chain of extensions. Remove function description for static functions. Move code around as per review feedback.v9: Changed some u32 to unsigned int. Moved some code around as per review feedback from v8.v8: Used div_u64 instead of / to fix 32-bit build issue. Changed copyright year in xe_eu_stall.c/h to 2025.v7: Renamed input property DRM_XE_EU_STALL_PROP_EVENT_REPORT_COUNT to DRM_XE_EU_STALL_PROP_WAIT_NUM_REPORTS to be consistent with OA. Renamed the corresponding internal variables. Fixed some commit messages based on review feedback.v6: Change the input sampling rate to GPU cycles instead of GPU cycles multiplier.Reviewed-by: Ashutosh Dixit Signed-off-by: Harish Chegondi Signed-off-by: Ashutosh Dixit Link: https://patchwork.freedesktop.org/patch/msgid/bb707a27975c33e4a912b9839b023acb7a1f9c90.1740533885.git.harish.chegondi@intel.com List of files: /linux-6.15/drivers/gpu/drm/xe/Makefile

Wed, 29 Jan 2025 17:41:26 +0000

drm/xe/pxp: Allocate PXP execution resourcesPXP requires submissions to the HW for the following operations1) Key invalidation, done via the VCS engine2) Communication with the GSC FW for session management, done via the GSCCS.Key invalidation submissions are serialized (only 1 termination can beserviced at a given time) and done via GGTT, so we can allocate a simpleBO and a kernel queue for it.Submissions for session management are tied to a PXP client (identifiedby a unique host_session_id); from the GSC POV this is a user-accessibleconstruct, so all related submission must be done via PPGTT. The driverdoes not currently support PPGTT submission from within the kernel, soto add this support, the following changes have been included:- a new type of kernel-owned VM (marked as GSC), required to ensure we don't use fault mode on the engine and to mark the different lock usage with lockdep.- a new function to map a BO into a VM from within the kernel.v2: improve comments and function name, remove unneeded include (John)v3: fix variable/function names in documentationSigned-off-by: Daniele Ceraolo Spurio Cc: Matthew Brost Cc: Thomas Hellström Cc: John Harrison Reviewed-by: John Harrison Link: https://patchwork.freedesktop.org/patch/msgid/20250129174140.948829-3-daniele.ceraolospurio@intel.com List of files: /linux-6.15/drivers/gpu/drm/xe/Makefile

Tue, 28 Jan 2025 09:56:30 +0000

drm/xe: Add functions and sysfs for boot survivabilityBoot Survivability is a software based workflow for recovering a systemin a failed boot state. Here system recoverability is concerned withrecovering the firmware responsible for boot.This is implemented by loading the driver with bare minimum (no drm card)to allow the firmware to be flashed through mei-gsc and collect telemetry.The driver's probe flow is modified such that it enters survivability modewhen pcode initialization is incomplete and boot status denotes a failure.In this mode, drm card is not exposed and presence of survivability_modeentry in PCI sysfs is used to indicate survivability mode andprovide additional information required for debugThis patch adds initialization functions and exposes adminreadable sysfs entriesThe new sysfs will have the below layout /sys/bus/.../bdf ├── survivability_modev2: reorder headers fix doc remove survivability info and use mode to display information use separate function for logging survivability information for critical error (Rodrigo)v3: use for loop use dev logs instead of drm use helper function for aux history(Rodrigo) remove unnecessary error check of greater than max_scratch as we are reading only 3 bitv4: fix checkpatch warnings fix space (Rodrigo) rename registerSigned-off-by: Riana Tauro Acked-by: Ashwin Kumar Kulkarni Reviewed-by: Rodrigo Vivi Link: https://patchwork.freedesktop.org/patch/msgid/20250128095632.1294722-2-riana.tauro@intel.comSigned-off-by: Rodrigo Vivi List of files: /linux-6.15/drivers/gpu/drm/xe/Makefile

f14d81b7 - drm/i915/cmtg: Disable the CMTG

Fri, 24 Jan 2025 17:38:14 +0000

drm/i915/cmtg: Disable the CMTGThe CMTG is a timing generator that runs in parallel with transcoderstiming generators and can be used as a reference for synchronization.We have observed that we are inheriting from GOP a display configurationwith the CMTG enabled. Because our driver doesn't currently implementany CMTG sequences, the CMTG ends up still enabled after our drivertakes over.We need to make sure that the CMTG is not enabled if we are not going touse it. For that, let's add a partial implementation in our driver thatonly cares about disabling the CMTG if it was found enabled duringinitial hardware readout. In the future, we can also implement sequencesfor using the CMTG if that becomes a needed feature.For now, we only deal with cases when it is possible to disable the CMTGwithout requiring a modeset. For earlier display versions, we simplyskip if we find the CMTG enabled and we can't disable it without aproper modeset. In the future, we need to properly handle that case.v2: - DG2 does not have the CMTG. Update HAS_CMTG() accordingly. - Update logic to force disabling of CMTG only for initial commit.v3: - Add missing changes for v2 that were staged but not committed.v4: - Avoid if/else duplication in intel_cmtg_dump_state() by using "n/a" for CMTG B enabled/disabled string for platforms without it. (Jani) - Prefer intel_cmtg_readout_hw_state() over intel_cmtg_readout_state(). (Jani) - Use display struct instead of i915 as first parameter for TRANS_DDI_FUNC_CTL2(). (Jani) - Fewer continuation lines in variable declaration/initialization for better readability. (Jani) - Coding style improvements. (Jani) - Use drm_dbg_kms() instead of drm_info() for logging the disabling of the CMTG. - Make struct intel_cmtg_state entirely private to intel_cmtg.c.v5: - Do the disable sequence as part of the sanitization step after hardware readout instead of initial modeset commit. (Jani) - Adapt to commit 15133582465f ("drm/i915/display: convert global state to struct intel_display") by using a display struct instead of i915 as argument for intel_atomic_global_obj_init().v6: - Do not track CMTG state as a global state. (Ville) - Simplify the driver logic by only disabling the CMTG only on cases when a modeset is not required. (Ville)v7: - Remove the call to drm_WARN_ON() when checking intel_cmtg_disable_requires_modeset() and use a FIXME in the comment instead. - Remove the !HAS_CMTG() guard from intel_cmtg_get_config(), which is static and its caller is already protected by that same condition. - Also take the opportunity to put some Bspec references in the commit trailers section.v8: - Use HAS_TRANSCODER() instead of intel_crtc_for_pipe(). (Ville) - Ensure transcoder power well is enabled before reading TRANS_DDI_FUNC_CTL2.

Mon, 04 Nov 2024 21:34:45 +0000

drm/xe/vf: React to MIGRATED interruptTo properly support VF Save/Restore procedure, fixups need to beapplied after PF driver finishes its part of VF Restore. The fixupsare required to adjust the ongoing execution for a hardware switchthat happened, because some GFX resources are not fully virtualized,and assigned to a VF as range from a global pool. The VF on whicha VM is restored will often have different ranges provisioned thanthe VF on which save process happened. Those resource fixups areapplied by the VF driver within a restored VM.A VF driver gets informed that it was migrated by receiving aninterrupt from each GuC. The interrupt assigned for that purposeis "GUC SW interrupt 0". Seeing that fields set from within theirq handler should be the trigger for fixups.The VF can safely do post-migration fixups on resources associatedto each GuC only after that GuC issued the MIGRATED interrupt.This change introduces a worker to be used for post-migration fixups,and a mechanism to schedule said worker when all GuCs sent the irq.v2: renamed and moved functions, updated logged messages, removed unused includes, used anon struct (Michal)v3: ordering, kerneldoc, asserts, debug messages, on_all_tiles -> on_all_gts (Michal)v4: fixed missing header includev5: Explained what fixups are, explained which IRQ is used, style fixes (Michal)Bspec: 50868Signed-off-by: Tomasz Lis Reviewed-by: Michal Wajdeczko Link: https://patchwork.freedesktop.org/patch/msgid/20241104213449.1455694-2-tomasz.lis@intel.comSigned-off-by: Michal Wajdeczko List of files: /linux-6.15/drivers/gpu/drm/xe/Makefile
