drm/{i915, xe}/reg: rename masked field helpers REG_MASKED_FIELD*()

2026-03-04T11:04:24+00:00

The underscore prefixed masked field helper names aren't great. Rename them REG_MASKED_FIELD(), REG_MASKED_FIELD_ENABLE(), and REG_MASKED_FIELD_DISABLE(). This is more in line with the existing REG_FIELD_PREP() etc. helpers, and using "field" instead of "bit" is more accurate for the functionality. This is done with: sed -i 's/_MASKED_FIELD/REG_MASKED_FIELD/g' $(git grep -wl _MASKED_FIELD) sed -i 's/_MASKED_BIT_ENABLE/REG_MASKED_FIELD_ENABLE/g' $(git grep -wl _MASKED_BIT_ENABLE) sed -i 's/_MASKED_BIT_DISABLE/REG_MASKED_FIELD_DISABLE/g' $(git grep -wl _MASKED_BIT_DISABLE) with some manual indentation fixes on top.

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook

drm/xe/reg_sr: Don't process gt/hwe lists in VF

2026-02-19T15:31:05+00:00

There are a few different reg_sr lists managed by the driver for workarounds/tuning: - gt->reg_sr - hwe->reg_sr - hwe->reg_lrc The first two are not relevant to SRIOV VFs; a VF KMD does not have access to the registers that appear on this list and it is the PF KMD's responsibility to apply such programming on behalf of the entire system. However the third list contains per-client values that the VF KMD needs to ensure are incorporated whenever a new LRC is created. Handling of reg_sr lists comes in two steps: processing an RTP table to build a reg_sr from the relevant entries, and then applying the contents of the reg_sr. Skipping the RTP processing (resulting in an empty reg_sr) or skipping the application of a reg_sr are both valid ways to avoid having a VF accidentally try to write registers it doesn't have access to. In commit c19e705ec981 ("drm/xe/vf: Stop applying save-restore MMIOs if VF") and commit 92a5bd302458 ("drm/xe/vf: Unblock xe_rtp_process_to_sr for VFs") we adjusted the drivers behavior to always process the RTP table into a reg_sr and just skipped the application step. This works fine functionally, but can lead to confusion during debugging since facilities like the debugfs 'register-save-restore' will still report a bunch of registers that the VF KMD isn't actually trying to handle. It will also mislead other upcoming debug changes. Let's go back to skipping the RTP => reg_sr processing step, but only for GT / hwe tables this time. This will allow LRC reg_sr handling to continue to work, but will ensure that gt->reg_sr and hwe->reg_sr remain empty and that debugfs reporting more accurately reflects the KMD's behavior. v2: - Also skip the hwe processing in hw_engine_setup_default_state() and xe_reg_whitelist_process_engine(). v3: - Handle skipping via an additional parameter passed to xe_rtp_process_to_sr() rather than adding conditions at each callsite.

drm/xe: Cleanup unused header includes

2026-01-15T15:05:04+00:00

clangd reports many "unused header" warnings throughout the Xe driver. Start working to clean this up by removing unnecessary includes in our .c files and/or replacing them with explicit includes of other headers that were previously being included indirectly. By far the most common offender here was unnecessary inclusion of xe_gt.h. That likely originates from the early days of xe.ko when xe_mmio did not exist and all register accesses, including those unrelated to GTs, were done with GT functions. There's still a lot of additional #include cleanup that can be done in the headers themselves; that will come as a followup series. v2: - Squash the 79-patch series down to a single patch.
