2025-04-18	drm/xe/pxp: do not queue unneeded terminations from debugfs	Daniele Ceraolo Spurio	1	-2/+11
	The PXP terminate debugfs currently unconditionally simulates a termination, no matter what the HW status is. This is unneeded if PXP is not in use and can cause errors if the HW init hasn't completed yet. To solve these issues, we can simply limit the terminations to the cases where PXP is fully initialized and in use. v2: s/pxp_status/ready/ to avoid confusion with pxp->status (John) Fixes: 385a8015b214 ("drm/xe/pxp: Add PXP debugfs support") Closes: https://gitlab.freedesktop.org/drm/xe/kernel/-/issues/4749 Signed-off-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: John Harrison <John.C.Harrison@Intel.com> Reviewed-by: John Harrison <John.C.Harrison@Intel.com> Link: https://lore.kernel.org/r/20250416201622.1295369-1-daniele.ceraolospurio@intel.com (cherry picked from commit ba1f62a0cac84757ca35f4217e3cd3a2654233ae) Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com>
2025-02-03	drm/xe/pxp: Add PXP debugfs support	Daniele Ceraolo Spurio	1	-0/+120
	This patch introduces 2 PXP debugfs entries: - info: prints the current PXP status and key instance - terminate: simulate a termination interrupt The first one is useful for debug, while the second one can be used for testing the termination flow. v2: move the info prints inside the lock (John) Signed-off-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: John Harrison <John.C.Harrison@Intel.com> Reviewed-by: John Harrison <John.C.Harrison@Intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20250129174140.948829-13-daniele.ceraolospurio@intel.com
