Huang, Sean Z 2ae096872a drm/i915/pxp: Implement PXP irq handler ... The HW will generate a teardown interrupt when session termination is required, which requires i915 to submit a terminating batch. Once the HW is done with the termination it will generate another interrupt, at which point it is safe to re-create the session. Since the termination and re-creation flow is something we want to trigger from the driver as well, use a common work function that can be called both from the irq handler and from the driver set-up flows, which has the addded benefit of allowing us to skip any extra locks because the work itself serializes the operations. v2: use struct completion instead of bool (Chris) v3: drop locks, clean up functions and improve comments (Chris), move to common work function. v4: improve comments, simplify wait logic (Rodrigo) v5: unconditionally set interrupts, rename state_attacked var (Rodrigo) v10: remove inclusion of intel_gt_types.h from intel_pxp.h (Jani) Signed-off-by: Alan Previn <alan.previn.teres.alexis@intel.com> Signed-off-by: Huang, Sean Z <sean.z.huang@intel.com> Signed-off-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Reviewed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210924191452.1539378-10-alan.previn.teres.alexis@intel.com		2021-10-04 13:10:55 -04:00
