[PATCH v6 00/14] GSC support for XeHP SDV and DG2

From: Tomas Winkler
Date: Sun Jul 24 2022 - 04:24:55 EST


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

Greg KH, please review and ACK the MEI patches.
We are pushing these patches through gfx tree as
the auxiliary device belongs there.

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
