* gpu: nvgpu: keep usermode region flags on railgateKonsta Hölttä2021-06-24
| | | | | | | | | | | | | | | | | | | | | | | When the gpu is railgated, the usermode region mappings must be cleared. This is already done with zap_vma_ptes() but as an extra measure the vm flags are also zeroed. That is an oversight, so delete that code; in particular the VM_DONTCOPY flag is important so that the mapping does not follow fork, as the design does not allow that.

* gpu: nvgpu: handle ioctl l2_fb_ops betterddutta2020-03-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Background: There is a race that occurs when l2_fb_ops ioctl is invoked. The race occurs as part of the flush() call while a gk20_idle() is in progress. This patch handles the race by making changes in the l2_fb_ops ioctl itself. For cases where pm_runtime is disabled or railgate is disabled, we allow this ioctl call to always go ahead as power is assumed to be always on. For the other case, we first check the status of g->power_on. In the driver, g->power_on is set to true, once unrailgate is completed and is set to false just before calling railgate. For linux, the driver invokes gk20a_idle() but there is a delay after which the call to the rpm_suspend()'s callback gets triggered. This leads to a scenario where we cannot efficiently rely on the runtime_pm's APIs to allow us to block an imminent suspend or exit if the suspend is currently in progress. Previous attempts at solving this has lead to ineffective solutions and make it much complicated to maintain the code. With regards to the above, this patch attempts to simplify the way this can be solved. The patch calls gk20a_busy() when g->power_on = true. This prevents the race with gk20a_idle(). Based on the rpm_resume and rpm_suspend's upstream code, resume is prioritized over a suspend unless a suspend is already in progress i.e. the delay period has been served and the suspend invokes the callback. There is a very small window for this to happen and the ioctl can then power_up the device as evident from the gk20a_busy's calls. A new function gk20a_check_poweron() is added. This function protects the access to g->power_on via a mutex. By preventing a read from happening simulatenously as a write on g->power_on, the likelihood of an runtime_suspend triggering before a runtime_resume is further reduced.

* gpu: nvgpu: Fix the race between runtime PM and L2 flushDebarshi Dutta2019-08-02
| | | | | | | | | | | | | | | | | | | | | | | | | | gk20a_mm_l2_flush flushes the L2 cache when "struct gk20a->power_on" is true. But it doesn't acquire power lock when doing that, which creates a race that runtime PM might suspend the GPU in the middle of L2 flush. The FB flush looks having the same issue with L2 flushing. This patch fixes that by calling pm_runtime_get_if_in_use at the beginning of the ioctl. This API from PM does a compare and add to the usage count. If the device was not in use, it simply returns without incrementing the usage count as its unnecessary to wake up the GPU(using e.g. a call to gk20a_busy()) as the caches are flushed when the device would be resumed anyways.

Moved the struct to save the sm_error details from gr to tsg as the sm_error support is context based, not global. Also corrected MISRA 21.1 error in header file. nvgpu_dbg_gpu_ioctl_write_single_sm_error_state and nvgpu_dbg_gpu_ioctl_read_single_sm_error_state functions are modified to use the tsg struct nvgpu_tsg_sm_error_state.

| | | | | | | | | | | | | | | | | clk_arb.h and gk20a.h has circular dependencies to each other. This is removed by forward declaring struct gk20a in clk_arb.h and removing the header gk20a.h from clk_arb.h and similarly forward declaring struct nvgpu_clk_arb in gk20a.h and removing the header clk_arb.h from gk20a.h alongwith putting headers in every execution unit which calls clk_arb.h related methods.
