Typically, firmware for these devices are part of IFWI flash image but can be replaced at probe after OEM tuning. v2: - Dropped voltage regulator specific code as binaries for it will not be available for upstreaming as of now. - Address review comments v3: - Dropped fwctl patch for now - Added new patch to extract binary version - Address v2 review comments Alexander Usyskin (2): mei: bus: add mei_cldev_mtu interface mei: late_bind: add late binding component driver Badal Nilawar (8): drm/xe/xe_late_bind_fw: Introducing xe_late_bind_fw drm/xe/xe_late_bind_fw: Initialize late binding firmware drm/xe/xe_late_bind_fw: Load late binding firmware drm/xe/xe_late_bind_fw: Reload late binding fw in rpm resume drm/xe/xe_late_bind_fw: Reload late binding fw in S2Idle/S3 resume drm/xe/xe_late_bind_fw: Introduce debug fs node to disable late binding drm/xe/xe_late_bind_fw: Extract and print version info [CI]drm/xe/xe_late_bind_fw: Select INTEL_MEI_LATE_BIND for CI drivers/gpu/drm/xe/Kconfig | 1 + drivers/gpu/drm/xe/Makefile | 1 + drivers/gpu/drm/xe/xe_debugfs.c | 41 ++ drivers/gpu/drm/xe/xe_device.c | 5 + drivers/gpu/drm/xe/xe_device_types.h | 6 + drivers/gpu/drm/xe/xe_late_bind_fw.c | 432 ++++++++++++++++++++ drivers/gpu/drm/xe/xe_late_bind_fw.h | 17 + drivers/gpu/drm/xe/xe_late_bind_fw_types.h | 82 ++++ drivers/gpu/drm/xe/xe_pci.c | 3 + drivers/gpu/drm/xe/xe_pm.c | 9 + drivers/gpu/drm/xe/xe_uc_fw_abi.h | 69 ++++ drivers/misc/mei/Kconfig | 1 + drivers/misc/mei/Makefile | 1 + drivers/misc/mei/bus.c | 13 + drivers/misc/mei/late_bind/Kconfig | 13 + drivers/misc/mei/late_bind/Makefile | 9 + drivers/misc/mei/late_bind/mei_late_bind.c | 263 ++++++++++++ include/drm/intel/i915_component.h | 1 + include/drm/intel/late_bind_mei_interface.h | 50 +++ include/linux/mei_cl_bus.h | 1 + 20 files changed, 1018 insertions(+) create mode 100644 drivers/gpu/drm/xe/xe_late_bind_fw.c create mode 100644 drivers/gpu/drm/xe/xe_late_bind_fw.h create mode 100644 drivers/gpu/drm/xe/xe_late_bind_fw_types.h create mode 100644 drivers/misc/mei/late_bind/Kconfig create mode 100644 drivers/misc/mei/late_bind/Makefile create mode 100644 drivers/misc/mei/late_bind/mei_late_bind.c create mode 100644 include/drm/intel/late_bind_mei_interface.h -- 2.34.1
