Subject: [PATCH v7 00/15] GSC support for XeHP SDV and DG2
Date:   Sat,  6 Aug 2022 15:26:21 +0300

Add GSC support for XeHP SDV and DG2 platforms.

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.


Alexander Usyskin (4):
  drm/i915/gsc: add slow_firmware flag to the gsc device definition
  drm/i915/gsc: add GSC XeHP SDV platform definition
  mei: gsc: wait for reset thread on stop
  mei: extend timeouts on slow devices.

Daniele Ceraolo Spurio (1):
  HAX: drm/i915: force INTEL_MEI_GSC on for CI

Tomas Winkler (7):
  mei: add kdoc for struct mei_aux_device
  mei: add slow_firmware flag to the mei auxiliary device
  mei: gsc: use polling instead of interrupts
  mei: mkhi: add memory ready command
  mei: gsc: setup gsc extended operational memory
  mei: debugfs: add pxp mode to devstate in debugfs
  drm/i915/gsc: allocate extended operational memory in LMEM

Vitaly Lubart (3):
  drm/i915/gsc: skip irq initialization if using polling
  mei: bus: export common mkhi definitions into a separate header
  mei: gsc: add transition to PXP mode in resume flow
