2024-04-18	drm/xe/pm: Capture errors and handle them	Himal Prasad Ghimiray	1	-1/+1
	xe_pm_init may encounter failures for various reasons, such as a failure in initializing drmm_mutex, or when dealing with a d3cold-capable device for vram_threshold sysfs creation and setting default threshold. Presently, all these potential failures are disregarded. Move d3cold.lock initialization to xe_pm_init_early and cause driver abort if mutex initialization has failed. For xe_pm_init failures cleanup the driver and return error code -v2 Make mutex init cleaner (Lucas) Cc: Lucas De Marchi <lucas.demarchi@intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: Himal Prasad Ghimiray <himal.prasad.ghimiray@intel.com> Reviewed-by: Lucas De Marchi <lucas.demarchi@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240412181211.1155732-8-himal.prasad.ghimiray@intel.com Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com>
2023-12-21	drm/xe/pm: Add vram_d3cold_threshold Sysfs	Anshuman Gupta	1	-0/+13
	Add per pci device vram_d3cold_threshold Sysfs to control the d3cold allowed knob. Adding a d3cold structure embedded in xe_device to encapsulate d3cold related stuff. v2: - Check total vram before initializing default threshold. [Riana] - Add static scope to vram_d3cold_threshold DEVICE_ATTR. [Riana] v3: - Fixed cosmetics review comment. [Riana] - Fixed CI Hook failures. - Used drmm_mutex_init(). v4: - Fixed kernel-doc warnings. v5: - Added doc explaining need for the device sysfs. [Rodrigo] - Removed TODO comment.
