[PATCH v8 00/16] GSC support for XeHP SDV and DG2
From: Tomas Winkler
Date: Wed Sep 07 2022 - 17:51:38 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
This patch set should be merged via gfx tree as
the auxiliary device belongs there.
Acked-by: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx>
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.
V8:
1. Update copyright dates
1. Add kdoc and comments to mei_me_polling_thread()
2. Fix pgi->d0i3 timeout in mei_me_d0i3_enter_sync()
3. <linux/types.h> is enough for mkhi header.
4. drop MCHI_GROUP_ID definition it is not used
5. Setup default PXP state
6. Add PXP mode kdoc
7. Add new patch mei: drop ready bits check after start
V9:
1. Fix pgi->d0i3 timeout in mei_me_d0i3_exit_sync()
2. Fix mismatch in the patch "mei: mkhi: add memory ready command"
3. Use I915_BO_ALLOC_CPU_CLEAR to clear the allocated memory
