PXP (Protected Xe Path) is an i915 component, available on GEN12+, that helps to establish the hardware protected session and manage the status of the alive software session, as well as its life cycle. The main changes in v5 are: - Rebased to new proto_ctx implementation. - Squashed all uapi changes in a single patch and slightly updated docs. - Now handling mei_pxp loading after i915 Tested with: https://patchwork.freedesktop.org/series/87570/ Cc: Gaurav Kumar <kumar.gaurav@xxxxxxxxx> Cc: Chris Wilson <chris@xxxxxxxxxxxxxxxxxx> Cc: Rodrigo Vivi <rodrigo.vivi@xxxxxxxxx> Cc: Joonas Lahtinen <joonas.lahtinen@xxxxxxxxxxxxxxx> Cc: Juston Li <juston.li@xxxxxxxxx> Cc: Alan Previn <alan.previn.teres.alexis@xxxxxxxxx> Cc: Lionel Landwerlin <lionel.g.landwerlin@xxxxxxxxx> Cc: Jason Ekstrand <jason@xxxxxxxxxxxxxx> Cc: Daniel Vetter <daniel.vetter@xxxxxxxxx> Anshuman Gupta (2): drm/i915/pxp: Add plane decryption support drm/i915/pxp: black pixels on pxp disabled Daniele Ceraolo Spurio (7): drm/i915/pxp: Define PXP component interface drm/i915/pxp: define PXP device flag and kconfig drm/i915/pxp: allocate a vcs context for pxp usage drm/i915/pxp: set KCR reg init drm/i915/pxp: interfaces for using protected objects drm/i915/pxp: start the arb session on demand drm/i915/pxp: enable PXP for integrated Gen12 Huang, Sean Z (5): drm/i915/pxp: Implement funcs to create the TEE channel drm/i915/pxp: Create the arbitrary session after boot drm/i915/pxp: Implement arb session teardown drm/i915/pxp: Implement PXP irq handler drm/i915/pxp: Enable PXP power management Vitaly Lubart (1): mei: pxp: export pavp client to me client bus drivers/gpu/drm/i915/Kconfig | 11 + drivers/gpu/drm/i915/Makefile | 9 + .../gpu/drm/i915/display/intel_atomic_plane.c | 25 ++ drivers/gpu/drm/i915/display/intel_display.c | 4 + .../drm/i915/display/intel_display_types.h | 6 + .../drm/i915/display/skl_universal_plane.c | 49 +++- drivers/gpu/drm/i915/gem/i915_gem_context.c | 68 ++++- drivers/gpu/drm/i915/gem/i915_gem_context.h | 18 ++ .../gpu/drm/i915/gem/i915_gem_context_types.h | 2 + drivers/gpu/drm/i915/gem/i915_gem_create.c | 26 ++ .../gpu/drm/i915/gem/i915_gem_execbuffer.c | 42 ++- drivers/gpu/drm/i915/gem/i915_gem_object.c | 6 + drivers/gpu/drm/i915/gem/i915_gem_object.h | 12 + .../gpu/drm/i915/gem/i915_gem_object_types.h | 13 + drivers/gpu/drm/i915/gt/intel_engine.h | 2 + drivers/gpu/drm/i915/gt/intel_gpu_commands.h | 22 +- drivers/gpu/drm/i915/gt/intel_gt.c | 5 + drivers/gpu/drm/i915/gt/intel_gt_irq.c | 7 + drivers/gpu/drm/i915/gt/intel_gt_pm.c | 15 +- drivers/gpu/drm/i915/gt/intel_gt_types.h | 3 + drivers/gpu/drm/i915/i915_drv.c | 2 + drivers/gpu/drm/i915/i915_drv.h | 4 + drivers/gpu/drm/i915/i915_pci.c | 2 + drivers/gpu/drm/i915/i915_reg.h | 48 ++++ drivers/gpu/drm/i915/intel_device_info.h | 1 + drivers/gpu/drm/i915/pxp/intel_pxp.c | 268 ++++++++++++++++++ drivers/gpu/drm/i915/pxp/intel_pxp.h | 67 +++++ drivers/gpu/drm/i915/pxp/intel_pxp_cmd.c | 141 +++++++++ drivers/gpu/drm/i915/pxp/intel_pxp_cmd.h | 15 + drivers/gpu/drm/i915/pxp/intel_pxp_irq.c | 100 +++++++ drivers/gpu/drm/i915/pxp/intel_pxp_irq.h | 32 +++ drivers/gpu/drm/i915/pxp/intel_pxp_pm.c | 40 +++ drivers/gpu/drm/i915/pxp/intel_pxp_pm.h | 23 ++ drivers/gpu/drm/i915/pxp/intel_pxp_session.c | 172 +++++++++++ drivers/gpu/drm/i915/pxp/intel_pxp_session.h | 15 + drivers/gpu/drm/i915/pxp/intel_pxp_tee.c | 170 +++++++++++ drivers/gpu/drm/i915/pxp/intel_pxp_tee.h | 17 ++ .../drm/i915/pxp/intel_pxp_tee_interface.h | 37 +++ drivers/gpu/drm/i915/pxp/intel_pxp_types.h | 55 ++++ drivers/misc/mei/Kconfig | 2 + drivers/misc/mei/Makefile | 1 + drivers/misc/mei/pxp/Kconfig | 13 + drivers/misc/mei/pxp/Makefile | 7 + drivers/misc/mei/pxp/mei_pxp.c | 233 +++++++++++++++ drivers/misc/mei/pxp/mei_pxp.h | 18 ++ include/drm/i915_component.h | 1 + include/drm/i915_pxp_tee_interface.h | 45 +++ include/uapi/drm/i915_drm.h | 58 +++- 48 files changed, 1917 insertions(+), 15 deletions(-) create mode 100644 drivers/gpu/drm/i915/pxp/intel_pxp.c create mode 100644 drivers/gpu/drm/i915/pxp/intel_pxp.h create mode 100644 drivers/gpu/drm/i915/pxp/intel_pxp_cmd.c create mode 100644 drivers/gpu/drm/i915/pxp/intel_pxp_cmd.h create mode 100644 drivers/gpu/drm/i915/pxp/intel_pxp_irq.c create mode 100644 drivers/gpu/drm/i915/pxp/intel_pxp_irq.h create mode 100644 drivers/gpu/drm/i915/pxp/intel_pxp_pm.c create mode 100644 drivers/gpu/drm/i915/pxp/intel_pxp_pm.h create mode 100644 drivers/gpu/drm/i915/pxp/intel_pxp_session.c create mode 100644 drivers/gpu/drm/i915/pxp/intel_pxp_session.h create mode 100644 drivers/gpu/drm/i915/pxp/intel_pxp_tee.c create mode 100644 drivers/gpu/drm/i915/pxp/intel_pxp_tee.h create mode 100644 drivers/gpu/drm/i915/pxp/intel_pxp_tee_interface.h create mode 100644 drivers/gpu/drm/i915/pxp/intel_pxp_types.h create mode 100644 drivers/misc/mei/pxp/Kconfig create mode 100644 drivers/misc/mei/pxp/Makefile create mode 100644 drivers/misc/mei/pxp/mei_pxp.c create mode 100644 drivers/misc/mei/pxp/mei_pxp.h create mode 100644 include/drm/i915_pxp_tee_interface.h -- 2.32.0
