drm/xe: introduce xe_gt_reset and xe_gt_wait_for_reset

2025-01-15T10:32:50Z

Add synchronous version gt reset as there are few places where it is expected. Also add a wait helper to wait until gt reset is done.

drm/xe/xe_gt_debugfs: Update handling of xe_force_wake_get return

2024-10-17T14:17:08Z

With xe_force_wake_get() now returning the refcount-incremented domain mask, a non-zero return value in the case of XE_FORCEWAKE_ALL does not necessarily indicate success. Use xe_force_wake_ref_has_domain() determine the status of the call. Modify the return handling of xe_force_wake_get() accordingly and pass the return value to xe_force_wake_put(). v3 - return xe_wakeref_t instead of int in xe_force_wake_get() - xe_force_wake_put() error doesn't need to be checked. It internally WARNS on domain ack failure. v5 - return unsigned int for xe_force_wake_get() v6 - use helper xe_force_wake_ref_has_domain() Cc: Rodrigo Vivi Cc: Lucas De Marchi Signed-off-by: Himal Prasad Ghimiray Reviewed-by: Nirmoy Das Reviewed-by: Badal Nilawar Link: https://patchwork.freedesktop.org/patch/msgid/20241014075601.2324382-16-himal.prasad.ghimiray@intel.com Signed-off-by: Rodrigo Vivi

drm/xe/xe_gt_idle: add debugfs entry for powergating info

2024-09-06T16:13:30Z

Coarse Powergating is a power saving technique where Render and Media can be power-gated independently irrespective of the rest of the GT. For debug purposes, it is useful to expose the powergating information. v2: move to debugfs add details to commit message add per-slice status for media define reg bits in descending order (Matt Roper) v3: fix return statement fix kernel-doc use loop for media slices use helper function for status (Michal) v4: add pg prefix do not wake GT if in C6 (Badal) Signed-off-by: Riana Tauro Reviewed-by: Badal Nilawar Acked-by: Rodrigo Vivi Link: https://patchwork.freedesktop.org/patch/msgid/20240906071126.28078-3-riana.tauro@intel.com Signed-off-by: Rodrigo Vivi

drm/xe: Add debugfs to dump GuC's hwconfig

2024-08-16T18:07:11Z

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.

drm/xe/xe_gt_debugfs: Add synchronous gt reset debugfs

2024-06-06T17:31:33Z

We currently have debugfs support that allows the userspace to initiate an asynchronous gt reset on command. However, userspace may also wish to wait for the completion of the gt reset before performing any additional work. To that end, add a version of the force_reset gt debugfs function that operates synchronously.
