2020-09-22drm/msm: Fix premature purging of BOAkhil P Oommen1-4/+7
In the case where we have a back-to-back submission that shares the same BO, this BO will be prematurely moved to inactive_list while retiring the first submit. But it will be still part of the second submit which is being processed by the GPU. Now, if the shrinker happens to be triggered at this point, it will result in a premature purging of this BO. To fix this, we need to refcount BO while doing submit and retire. Then, it should be moved to inactive list when this refcount becomes 0.

2020-05-23drm/msm: Refactor address space initializationJordan Crouse1-38/+2
Refactor how address space initialization works. Instead of having the address space function create the MMU object (and thus require separate but equal functions for gpummu and iommu) use a single function and pass the MMU struct in. Make the generic code cleaner by using target specific functions to create the address space so a2xx can do its own thing in its own space. For all the other targets use a generic helper to initialize IOMMU but leave the door open for newer targets to use customization if they need it.

This is useful for implementing context robustness. A user context can regularly query the number of faults to see if it is responsible for any and if so it can invalidate itself.

Add a reference count to track how many times a particular chunk of iova memory is pinned (mapped) in the iomu and add msm_gem_unpin_iova to give up references. It is important to note that msm_gem_unpin_iova replaces msm_gem_put_iova because the new implicit behavior that an assigned iova in a given vma is now valid for the life of the buffer and what we are really focusing on is the use of that iova. For now the unmappings are lazy; once the reference counts go to zero they *COULD* be unmapped dynamically but that will require an outside force such as a shrinker or mm_notifiers. For now, we're just focusing on getting the counting right and setting ourselves up to be ready for the future.

Add trace events to track the progress of a GPU submission msm_gpu_submit occurs at the beginning of the submissions, msm_gpu_submit_flush happens when the submission is put on the ringbuffer and msm_submit_flush_retired is sent when the operation is retired. To make it easier to track the operations a unique sequence number is assigned to each submission and displayed in each event output so a human or a script can easily associate the events related to a specific submission.

2018-12-11drm/msm/gpu: Allocate the correct size for the GPU memptrsJordan Crouse1-1/+2
Allocate the correct buffer size for the GPU memptrs. The incorrect size hasn't affected us thus far since the incorrect size was larger than the intended size and we're still stuck on page sized granularity anyway but technically correct is the best kind of correct.

2018-12-11drm: msm: Use DRM_DEV_* instead of dev_*Mamta Shukla1-15/+15
Use DRM_DEV_INFO/ERROR/WARN instead of dev_info/err/debug to generate drm-formatted specific log messages so that it will be easy to differentiate in case of multiple instances of driver. Signed-off-by: Mamta Shukla <[email protected]> Signed-off-by: Rob Clark <[email protected]>
2018-11-30drm/msm: Fix task dump in gpu recoverySharat Masetty1-5/+4
The current recovery code gets a pointer to the task struct and does a few things all within the rcu_read_lock. This puts constraints on the types of gfp flags that can be used within the rcu lock. This patch instead gets a reference to the task within the rcu lock and releases the lock immediately, this way the task stays afloat until we need it and we also get to use the desired gfp flags.

2018-10-04drm/msm: re-factor devfreq codeSharat Masetty1-18/+25
The devfreq framework requires the drivers to provide busy time estimations. The GPU driver relies on the hardware performance counteres for the busy time estimations, but different hardware revisions have counters which can be sourced from different clocks. So the busy time estimation will be target dependent. Additionally on targets where the clocks are completely controlled by the on chip microcontroller, fetching and setting the current GPU frequency will be different. This patch aims to embrace these differences by re-factoring the devfreq code a bit. Signed-off-by: Sharat Masetty <[email protected]> Signed-off-by: Rob Clark <[email protected]>
2018-10-04drm/msm: suspend devfreq on initSharat Masetty1-0/+2
Devfreq turns on and starts recommending power level as soon as it is initialized. The GPU is still not powered on by the time the devfreq init happens and this leads to problems on GPU's where register access is needed to get/set power levels. So we start suspended and only restart devfreq when GPU is powered on. Signed-off-by: Sharat Masetty <[email protected]> Signed-off-by: Rob Clark <[email protected]>

2018-08-10drm/msm: Add A6XX device supportJordan Crouse1-1/+1
Add support for the A6XX family of Adreno GPUs. The biggest addition is the GMU (Graphics Management Unit) which takes over most of the power management of the GPU itself but in a ironic twist of fate needs a goodly amount of management itself. Add support for the A6XX core code, the GMU and the HFI (hardware firmware interface) queue that the CPU uses to communicate with the GMU.

Add a helper function to parse the clock names and set up the bulk data so we can take advantage of the bulk clock functions instead of rolling our own.

2018-07-30drm/msm/gpu: avoid deprecated do_gettimeofdayArnd Bergmann1-2/+2
All users of do_gettimeofday() have been removed, but this one recently crept in, along with an incorrect printing of the microseconds portion. This converts it to using ktime_get_real_timespec64() as a direct replacement, and adds the leading zeroes. I considered using monotonic times (ktime_get()) instead, but as this timestamp appears to only be used for humans rather than compared with other timestamps, the real time domain is probably good enough.

Capture the GPU state on a GPU hang and store it for later playback via the devcoredump facility. Only one crash state is stored at a time on the assumption that the first hang is usually the most interesting. The existing crash state can be cleared after capturing it and then a new one will be captured on the next hang.
