The series includes changes for the mei driver: - add ability to use polling instead of interrupts - add ability to use extended timeouts - setup extended operational memory for GSC The series includes changes for the i915 driver: - allocate extended operational memory for GSC - GSC on XeHP SDV offsets and definitions This patch set should be merged via gfx tree as the auxiliary device belongs there. Greg, your ACK is required for the drives/misc/mei code base, please review the patches. V2: rebase over merged DG1 series and DG2 enablement patch, fix commit messages V3: rebase over latest tip V4: add missed changelog in pxp dbugfs patch V5: rebase over latest tip fix changelog in pxp dbugfs patch put HAX patch last to the ease of merging reorder patches in the series V6: change prefix from 'drm/i915/gsc:' to 'mei' in patch: mei: add slow_fw flag to the mei auxiliary device Address following checkpatch warnings: CHECK:PREFER_KERNEL_TYPES: Prefer kernel type 'u32' over 'uint32_t' FILE: drivers/misc/mei/mkhi.h:54: + uint32_t flags; -:51: CHECK:UNNECESSARY_PARENTHESES: Unnecessary parentheses around 'cldev->bus->pxp_mode != MEI_DEV_PXP_INIT' #51: FILE: drivers/misc/mei/bus-fixup.c:257: + if (!cldev->bus->fw_f_fw_ver_supported && + (cldev->bus->pxp_mode != MEI_DEV_PXP_INIT) Remove some spurious code formatting changes in: drm/i915/gsc: allocate extended operational memory in LMEM V7: Add new patch to add kdoc for mei_aux_device structure. Rename slow_fw to slow_firmware flag. Use drm_dbg/err() functions instead of dev_dbg/err() in i195 codebase.
