treewide: refresh kmalloc_obj() conversions

2026-09-05T04:37:00+00:00

This is another run of the Coccinelle script for converting kmalloc()
family of allocations to kmalloc_obj() via the existing rules in
scripts/coccinelle/api/kmalloc_objs.cocci

This catches both the set of kmalloc() uses added since the first
kmalloc_obj() conversions in v7.0 and adds a large group missed in the
first pass due to Coccinelle not interacting well with the cleanup.h
scoped_...() family of macros[1]. I worked around this with spatch's
"--macro-file" argument to a file with all the scoped_...() macros mapped
to Coccinelle's YACFE_ITERATOR[2] as that was the closest viable control
flow indicator I could find.

Build tested allmodconfig on x86, arm64, arm, loongarch, mips, powerpc,
riscv, and s390 with no new warnings.

BackMerge tag 'v7.2' into drm-next

2026-08-20T00:58:44+00:00

Linux 7.2

There was a lot of conflicts this round between fixes and next,
and I'd like to get the merge resolutions that we have in drm-tip.

drm/amd/pm: silence uninitialized variable warnings

2026-08-12T13:44:35+00:00

Smatch complains that:

    drivers/gpu/drm/amd/amdgpu/../pm/swsmu/smu15/smu_v15_0_8_ppt.c:1964
    smu_v15_0_8_set_performance_level() error: uninitialized symbol 'ret'.

In this line there is an "if (ret)" condition where "ret" is either
zero or uninitialized.  Initialize "ret" at the start of the function to
avoid a potential uninitialized variable bug.  But also delete the
condition since it is never true.

drm/amd/pm: Keep sub-degree precision in Q10 temperatures

2026-08-12T13:36:24+00:00

The Q10 temperatures were rounded to whole degrees before being scaled
to millidegrees, losing sub-degree precision. Convert them while
preserving the fractional part.

Also, use the standard MILLIDEGREE_PER_DEGREE to represent
SMU_TEMPERATURE_UNITS_PER_CENTIGRADES.

2026-08-12T13:36:15+00:00

The Q10 socket power was rounded to whole watts before scaling to
milliwatts, so the reported value lost its sub-watt precision. Add
SMUQ10_TO_MILLIWATT to convert while keeping the fractional bits.

drm/amd/pm: smu_v14_0_0: use find_clk_level() for DPM level marking

2026-08-06T13:27:17+00:00

Replace the simple exact-match loop in emit_clk_levels with a call
to smu_v14_0_0_find_clk_level() introduced in patch 1.  The helper
already handles both exact and closest-match semantics.

Build a stack-local frequency table from the DPM levels (using
reverse index for SMU_MCLK since MemPstateTable stores levels
high-to-low), then call the helper once to find the active level.

The SMU reports time-filtered average frequencies that often do not
match any DPM table entry exactly.  Without closest-match fallback,
MCLK, FCLK and other clocks show DPM levels but never display the
* marker, breaking userspace tools that rely on it to identify the
active frequency.

drm/amd/pm: smu_v14_0_0: add SMU_DCEFCLK support in DPM frequency queries

2026-08-06T13:27:12+00:00

Add SMU_DCEFCLK case to smu_v14_0_1_get_dpm_freq_by_index and
smu_v14_0_0_get_dpm_freq_by_index using DcfClocks[] with
NumDcfClkLevelsEnabled bounds check. Add matching case in both
get_dpm_level_count functions.

Add SMU_DCEFCLK case in emit_clk_levels to list DCEF DPM levels.
No * marker is emitted since SmuMetrics_t has no DcfclkFrequency
field (same firmware limitation as Phoenix).

Without this, pp_dpm_dcefclk reports N/A on Strix Halo.

drm/amd/pm: add IP_VERSION(11,5,1) to vclk/dclk DPM sysfs whitelists

2026-08-06T13:27:07+00:00

Add IP_VERSION(11,5,1) to pp_dpm_vclk and pp_dpm_dclk visibility
whitelists so these sysfs entries are exposed on Strix Halo (GC
11.5.1). Add IP_VERSION(11,5,1) to pp_dpm_vclk1 and pp_dpm_dclk1
whitelists with the existing num_vcn_inst >= 2 guard since Strix
Halo has two VCN instances.

Without this, amd-smi reports N/A for VCLK0, VCLK1, DCLK0 and
DCLK1 clocks.
