2025-07-04drm/msm: Update register xmlRob Clark
Sync register xml from mesa commit eb3e0b7164a3 ("freedreno/a6xx: Split descriptors out into their own file"). Signed-off-by: Rob Clark <robin.clark@oss.qualcomm.com> Acked-by: Dmitry Baryshkov <dmitry.baryshkov@oss.qualcomm.com> Patchwork: https://patchwork.freedesktop.org/patch/662470/
2025-07-04drm/msm: Use drm_gpuvm types moreRob Clark
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.

2025-07-04drm/msm: Rename msm_gem_address_space -> msm_gem_vmRob Clark
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.

timer_delete[_sync]() replaces del_timer[_sync](). Convert the whole tree over and remove the historical wrapper inlines. Conversion was done with coccinelle plus manual fixups where necessary. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Ingo Molnar <mingo@kernel.org>
2024-10-27drm/msm/a6xx: Remove logically deadcode in a6xx_preempt.cEverest K.C.
The ternary operator never returns -1 as `ring` will never be NULL. Thus, the ternary operator is not needed. Fix this by removing the ternary operation and only including the value it will return when the `ring` is not NULL.

Use the postamble to reset perf counters when switching between rings, except when sysprof is enabled, analogously to how they are reset between submissions when switching pagetables.

2024-10-03drm/msm/a6xx: Implement preemption for a7xx targetsAntonino Maniscalco
This patch implements preemption feature for A6xx targets, this allows the GPU to switch to a higher priority ringbuffer if one is ready. A6XX hardware as such supports multiple levels of preemption granularities, ranging from coarse grained(ringbuffer level) to a more fine grained such as draw-call level or a bin boundary level preemption. This patch enables the basic preemption level, with more fine grained preemption support to follow.
