* gpu: nvgpu: handle pm suspend/resume with runtime pm disableseshendra Gadagottu2018-04-02
| | | | | | | | | | | | | | | | | | | | | When runtime pm is disabled, then gpu rail will be on as soon as nvgpu module is loaded. If pm suspend/resume called before gpu hw initialization(g->poweron = false) then pm suspend is skipping gpu railgate, which is causing issues with SC7 entry/exit. To fix this issue: 1. During pm suspend, if g->poweron is false, check for runtime pm disable to railgate gpu rail. 2. On pm resume, check for runtime pm disable to enable gpu rail, though gpu driver not initialized.

The aync-probe was causing an issue because the arm-gic set_type did not have the proper locking constructs to prevent races in gic distributor.

While doing this, the meaning of nvgpu_semaphore_incr() changes, so rename it to nvgpu_semaphore_prepare(). Now it's only used to prepare an nvgpu_semaphore for a value that the HW will increment the sema to. Also change the BUG_ON that guards sema double-inits into just WARN_ON.

* gpu: nvgpu: allow syncfds as prefences on deterministicKonsta Holtta2018-03-23
| | | | | | | | | | | | | | | | | | | | | | Accept submits on deterministic channels even when the prefence is a syncfd, but only if it has just one fence inside. Because NVGPU_SUBMIT_GPFIFO_FLAGS_SYNC_FENCE is shared between pre- and postfences, a postfence (SUBMIT_GPFIFO_FLAGS_FENCE_GET) is not allowed at the same time though. The sync framework is problematic for deterministic channels due to certain allocations that are not controlled by nvgpu. However, that only applies for postfences, yet we've disallowed FLAGS_SYNC_FENCE for deterministic channels even when a postfence is not needed.

| | | | | | | | | | | | | | | | | | | | When generating the aperture field for the PDE being programmed we must use the next PD not the current PD. This is important for cases on the dGPU where VIDMEM runs out. In such cases the page table may reside in both VIDMEM and SYSMEM. Thus, if a PDE points to a PDE in a different type of memory (VIDMEM -> SYSMEM or SYSMEM -> VIDMEM) then the aperture will not be programmed correctly if the code uses the current PD for picking the next PD aperture.
