vmap'ing is just pinning in disguise. So treat it as such and simplify the LRU tracking. Signed-off-by:

We need to use the inuse count to track that a BO is pinned until we have the hw_fence. But we want to remove the obj lock from the job_run() path as this could deadlock against reclaim/shrinker (because it is blocking the hw_fence from eventually being signaled). So split that tracking out into a per-vma lock with narrower scope. Signed-off-by:

Stop open coding VMA construction, which will be needed in the next commit. And since the VMA already has a ptr to the adress space, stop passing that around everywhere. (Also, an aspace always has an mmu so we can drop a couple pointless NULL checks.) Signed-off-by:

The flags are only accessed (1) when submit is constructed, before enqueuing to gpu sched (ie. when still visible to only the task calling the submit ioctl), (2) here, where we own a reference to the submit and are serialized on the gpu sched thread, and (3) after the submit is retired and last reference is dropped, which is serialized on the submit's reference count. Hence locking is unneeded here. Signed-off-by:

The runtime PM status can only be updated while runtime PM is disabled. Drop the bogus pm_runtime_set_active() call that was made after enabling runtime PM and which (incidentally but correctly) left the runtime PM status set to 'suspended'. Fixes: 2c087a33 ("drm/msm/adreno: Load the firmware before bringing up the hardware") Signed-off-by:
-
Johan Hovold authored
A recent commit moved enabling of runtime PM to GPU load time (first open()) but failed to update the error paths so that runtime PM is disabled if initialisation of the GPU fails. This would trigger a warning about the unbalanced disable count on the next open() attempt. Note that pm_runtime_put_noidle() is sufficient to balance the usage count when pm_runtime_put_sync() fails (and is chosen over pm_runtime_resume_and_get() for consistency reasons).

Konrad Dybcio authored
Some older GPUs (namely a2xx with no opp tables at all and a320 with downstream-remnants gpu pwrlevels) used not to have OPP tables. They both however had just one frequency defined, making it extremely easy to construct such an OPP table from within the driver if need be. Do so and switch all clk_set_rate calls on core_clk to their OPP counterparts. Reviewed-by:

As per the recommended recovery sequence of adreno gpu, cx gdsc should collapse at hardware before it is turned back ON. This helps to clear out the stale states in hardware before it is reinitialized. Use the genpd notifier along with the newly introduced dev_pm_genpd_synced_poweroff() api to ensure that cx gdsc has collapsed before we turn it back ON. Signed-off-by:

Remove the unused 'reset' interface which was supposed to help to ensure that cx gdsc has collapsed during gpu recovery. This is was not enabled so far due to missing gpucc driver support. Similar functionality using genpd framework will be implemented in the upcoming patch. This effectively reverts commit 1f6cca40 ("drm/msm/a6xx: Ensure CX collapse during gpu recovery").

When a device has multiple power domains, dev->power_domain is left empty during probe. That didn't cause any issue so far because we are freeloading on smmu driver's vote on cx gdsc. Instead of that, create a device_link between cx genpd device and gmu device to keep a vote from gpu driver. Before this patch: localhost ~ # cat /sys/kernel/debug/pm_genpd/pm_genpd_summary gx_gdsc on 0 /devices/genpd:1:3d6a000.gmu active 0 cx_gdsc on 0 /devices/platform/soc@0/3da0000.iommu active 0 After this patch: localhost ~ # cat /sys/kernel/debug/pm_genpd/pm_genpd_summary gx_gdsc on 0 /devices/genpd:1:3d6a000.gmu active 0 cx_gdsc on 0 /devices/platform/soc@0/3da0000.iommu active 0 /devices/genpd:0:3d6a000.gmu active 0 Signed-off-by: -
