drm/msm/a6xx: Allow IFPC with perfcntr stream

2026-05-29T14:07:30+00:00

Now that the dynamic pwrup reglist has SEL reg values to restore appended, so that SEL regs are restored on IFPC exit, we can stop completely disabling IFPC while global counter sampling is active. To accomplish this, we re-use sysprof_setup() with a force_on param to inhibit IFPC specifically while the counter regs are being read, while leaving IFPC enabled the rest of the time.

drm/msm: Add per-context perfcntr state

2026-05-29T14:07:28+00:00

The upcoming PERFCNTR_CONFIG ioctl will allow for both global counter collection, and per-context counter reservation for local (ie. within a single GEM_SUBMIT ioctl) counter collection. Any number of contexts can reserve the same counters, but we will need to ensure that counters reserved for local counter collection do not conflict with counters used for global counter collection. So add tracking for per-context local counter reservations.

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/msm/adreno: Disable IFPC when sysprof is active

2025-09-08T14:25:00+00:00

Moving to IFPC state clears the 'Perfcounter Select' register setup by the userspace. So, lets block the IFPC when sysprof is active by using the perfcounter oob signal to the GMU. Signed-off-by: Akhil P Oommen Patchwork: https://patchwork.freedesktop.org/patch/673380/ Signed-off-by: Rob Clark

drm/msm: Use drm_gpuvm types more

2025-07-05T00:48:35+00:00

Most of the driver code doesn't need to reach in to msm specific fields, so just use the drm_gpuvm/drm_gpuva types directly. This should hopefully improve commonality with other drivers and make the code easier to understand.

Re-aligning naming to better match drm_gpuvm terminology will make things less confusing at the end of the drm_gpuvm conversion. This is just rename churn, no functional change.
