This patch series is to allow the kernel space to create and manage a single hardware session (a.k.a. default session or arbitrary session). So user can allocate the protected buffer, which is encrypted with the leverage of the arbitrary hardware session. v2: - modification based on code review feedbacks received - passing pxp instead of i915 as function argument - remove dead code only for multi-session - move the pxp init call from i915_drv.c to intel_gt.c - remove the tautology naming v3: - rebase to latest drm-tip v4: - Append the split non-mesa patch sereis (commit #14 - #21) into this patch series v5: - include "intel_pxp.h" in intel_pxp_sm.h at commit #14 to fix the build problem. v6: - Fix the null pointer arb_session access bug in intel_pxp_arb.c in "04 [RFC-v5] drm/i915/pxp: Create the arbitrary session after boot" v7: - Use list_for_each_entry_safe instead of list_for_each_entry v8: - Add MEI vtag support for PXP multi-session usage v9: - Fix error handling bug in commit #5 "Func to send hardware session termination". In intel_pxp_cmd.c, we should properly assign "err = PTR_ERR(x)" if hitting the error case "IS_ERR(x)", this is the only change in v9. v10 - Remove the multi session commits #14-#21, for now we would like to keep the multi session patches as downstream. - Adopt the code review suggestion from Wilson in commit #1 v11 - In commit #05 "drm/i915/pxp: Func to send hardware session termination", we should not assume VCS0 is always on. Instead we use available VCS#, could be VCS0, VCS2, etc. v12 - Add "#include in #1 intel_pxp_types.h v13 - Add "#include in #1 intel_pxp_types.h (#v12 didn't actually update the _types.h file...) v14 - Add "if (INTEL_GEN(gt->i915) < 12) return;" in #1 intel_pxp_fini(), just skip for non gen12+ sku v15 In #04: - Make intel_pxp_arb_reserve_session() as static function to fix the sparse warning - Update value of PXP_TEE_ARB_CMD_BIN v16 In #04: - Remove the binary from source code via defining the TEE command header v17 In #04, directly return intel_pxp_tee_component_fini() if pxp_tee_comp_added is off v18 - In #09, Add intel_pxp_gem_context_set_protected() to check the arb session before setting protected flag for gem context - In #12, Replace i915_gem_context_set_protected() with intel_pxp_gem_context_set_protected() to check whether the arbitrary session is alive Anshuman Gupta (1): drm/i915/pxp: Add plane decryption support Bommu Krishnaiah (2): drm/i915/uapi: introduce drm_i915_gem_create_ext drm/i915/pxp: User interface for Protected buffer Huang, Sean Z (9): drm/i915/pxp: Introduce Intel PXP component drm/i915/pxp: set KCR reg init during the boot time drm/i915/pxp: Implement funcs to create the TEE channel drm/i915/pxp: Create the arbitrary session after boot drm/i915/pxp: Func to send hardware session termination drm/i915/pxp: Enable PXP irq worker and callback stub drm/i915/pxp: Destroy arb session upon teardown drm/i915/pxp: Enable PXP power management drm/i915/pxp: Expose session state for display protection flip Vitaly Lubart (1): mei: pxp: export pavp client to me client bus drivers/gpu/drm/i915/Kconfig | 22 ++ drivers/gpu/drm/i915/Makefile | 9 + drivers/gpu/drm/i915/display/intel_sprite.c | 21 +- drivers/gpu/drm/i915/gem/i915_gem_context.c | 19 +- drivers/gpu/drm/i915/gem/i915_gem_context.h | 5 + .../gpu/drm/i915/gem/i915_gem_context_types.h | 2 +- .../gpu/drm/i915/gem/i915_gem_object_types.h | 5 + drivers/gpu/drm/i915/gt/intel_gt.c | 4 + drivers/gpu/drm/i915/gt/intel_gt_irq.c | 4 + drivers/gpu/drm/i915/gt/intel_gt_pm.c | 4 + drivers/gpu/drm/i915/gt/intel_gt_types.h | 3 + drivers/gpu/drm/i915/i915_drv.c | 7 +- drivers/gpu/drm/i915/i915_drv.h | 6 + drivers/gpu/drm/i915/i915_gem.c | 63 +++- drivers/gpu/drm/i915/i915_reg.h | 4 +- drivers/gpu/drm/i915/pxp/intel_pxp.c | 181 ++++++++++++ drivers/gpu/drm/i915/pxp/intel_pxp.h | 81 +++++ drivers/gpu/drm/i915/pxp/intel_pxp_arb.c | 207 +++++++++++++ drivers/gpu/drm/i915/pxp/intel_pxp_arb.h | 17 ++ drivers/gpu/drm/i915/pxp/intel_pxp_cmd.c | 278 ++++++++++++++++++ drivers/gpu/drm/i915/pxp/intel_pxp_cmd.h | 20 ++ drivers/gpu/drm/i915/pxp/intel_pxp_context.c | 28 ++ drivers/gpu/drm/i915/pxp/intel_pxp_context.h | 15 + drivers/gpu/drm/i915/pxp/intel_pxp_pm.c | 65 ++++ drivers/gpu/drm/i915/pxp/intel_pxp_pm.h | 31 ++ drivers/gpu/drm/i915/pxp/intel_pxp_tee.c | 207 +++++++++++++ drivers/gpu/drm/i915/pxp/intel_pxp_tee.h | 17 ++ drivers/gpu/drm/i915/pxp/intel_pxp_types.h | 60 ++++ 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 | 230 +++++++++++++++ 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 | 66 +++++ 37 files changed, 1756 insertions(+), 12 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_arb.c create mode 100644 drivers/gpu/drm/i915/pxp/intel_pxp_arb.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_context.c create mode 100644 drivers/gpu/drm/i915/pxp/intel_pxp_context.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_tee.c create mode 100644 drivers/gpu/drm/i915/pxp/intel_pxp_tee.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 -- 2.17.1 _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/intel-gfx
