Subject[PATCH v7 00/15] GSC support for XeHP SDV and DG2
Date
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

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
