* gpu: nvgpu: enable/disable tegra fuse clockseshendra Gadagottu2017-11-10
| | | | | | | | | | | | | | | | | | | | | | | | GPU hardware block needs tegra fuse clock to mirror gpu fuses from tegra fuses to gpu domain. Tegra fuse driver provided following APIs to enable/disable tegra fuse clock: int tegra_fuse_clock_enable(void); int tegra_fuse_clock_disable(void); To ensure that tegra fuse clock is disabled by nvgpu driver when gpu hardware block is not in use by: Calling tegra_fuse_clock_enable() while doing gk20a_pm_unrailgate() and calling tegra_fuse_clock_disable() while doing gk20a_pm_railgate().

* gpu: nvgpu: Move fuse override DT handlingTerje Bergstrom2017-11-09
| | | | | | | | | | | | | | | | | | | | | | Move fuse override DT handling to Linux code. All the chip specific fuse override functions did the same thing, so delete the HAL and call the same function to read the DT overrides on all chips. Also remove the fuse override functionality from dGPU. There are no DT entries for PCIe devices, so it would've failed anyway.

| | | | | | | | | | | | | | | | | | | Split the ctxsw trace "core" API code into <nvgpu/ctxsw_trace.h>. This is not perect though since there's some Linuxisms present in the HAL and as such that code has to be hidden by the ctxsw tracing CONFIG. But this patch should work for QNX such that it will allow the code to build as long as CONFIG_GK20A_CTXSW_TRACE is not set. Also fix the copywrite notice in the ctxsw code present under common/linux to be GPL.

* gpu: nvgpu: Move ctxsw_trace_gk20a.c to common/linuxAlex Waterman2017-10-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Migrate ctxsw_trace_gk20a.c to common/linux/ctxsw_trace.c. This has been done becasue the ctxsw tracing code is currently too tightly tied to the Linux OS due to usage of a couple system calls: - poll() - mmap() And general Linux driver framework code. As a result pulling the logic out of the FECS tracing code is simply too large a scope for time time being. Instead the code was just copied as much as possible. The HAL ops for the FECS code was hidden behind the FECS tracing config so that the vm_area_struct is not used when QNX does not define said config. All other non-HAL functions called by the FECS ctxsw tracing code ha now also been hidden by this config. This is not pretty but for the time being it seems like the way to go.

* gpu: nvgpu: Remove gk20a_scale_notify_busy/idle() hooksPeter Boonstoppel2017-06-29
| | | | | | | | | | | | | | | | Remove dependency for nvgpu to invoke devfreq govenor on every gk20a_busy/idle() call. This dependency was originally necessary to track GPU load (busy vs idle) in software. However, since we currently read the load GPU from HW/PMU there is no need to invoke the devfreq governor in this path. Instead it can use timer-based polling.

| | | | | | | | | | | | | | | | | | | | To make do_idle work when nvgpu is built as a module, reverse the order of call dependencies for do_idle. Don't provide visible gk20a_do_{idle,unidle}() functions for the kernel but instead call the kernel for registering and unregistering pointers to them when the driver loads and unloads. Refactor the internal __gk20a_do_{idle,unidle} functions to take a struct gk20a * instead of struct device *, and use the callback api for providing that g instead of retrieving the plat device from device tree.

* gpu: nvgpu: hold power ref for deterministic channelsKonsta Holtta2017-06-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To support deterministic channels even with platforms where railgating is supported, have each deterministic-marked channel hold a power reference during their lifetime, and skip taking power refs for jobs in submit path for those. Previously, railgating blocked deterministic submits in general because of gk20a_busy()/gk20a_idle() calls in submit path possibly taking time and more significantly because the gpu may need turning on which takes a nondeterministic and long amount of time. As an exception, gk20a_do_idle() can still block deterministic submits until gk20a_do_unidle() is called. Add a rwsem to guard this. VPR resize needs do_idle, which conflicts with deterministic channels' requirement to keep the GPU on. This is documented in the ioctl header now. Make NVGPU_GPU_FLAGS_SUPPORT_DETERMINISTIC_SUBMIT_NO_JOBTRACKING always set in the gpu characteristics now that it's supported. The only thing left now blocking NVGPU_GPU_FLAGS_SUPPORT_DETERMINISTIC_SUBMIT_FULL is the sync framework. Make the channel debug dump show which channels are deterministic.
