* gpu: nvgpu: Remove support for legacy mappingSami Kiminki2017-11-08
| | | | | | | | | | | | | | | | | | | | Make NVGPU_AS_MAP_BUFFER_FLAGS_DIRECT_KIND_CTRL mandatory for all map IOCTLs. We'll clean up the legacy kernel code in subsequent patches. Remove support for NVGPU_AS_IOCTL_MAP_BUFFER. It has been superseded by NVGPU_AS_IOCTL_MAP_BUFFER_EX. Remove legacy definitions to nvgpu_map_buffer_args and the related flags, and update the in-kernel map calls accordingly by switching to the newer definitions.

* gpu: nvgpu: support tuning per-ch deterministic optsKonsta Holtta2017-11-06
| | | | | | | | | | | | | | | | Add a new ioctl NVGPU_GPU_IOCTL_SET_DETERMINISTIC_OPTS to adjust deterministic options on a per-channel basis. Currently, the only supported option is to relax the no-railgating requirement on open deterministic channels. This also disallows submits on such channels, until the railgate option is reset.

* gpu: nvgpu: add max_css_buffer_size characteristicPeter Daifuku2017-10-25
| | | | | | | | | | | | | | | | | | | | | | | | Add max_css_buffer_size to gpu characteristics. In the virtual case, the size of the cycle stats snapshot buffer is constrained by the size of the mempool shared between the guest OS and the RM server, so tools need to find out what is the maximum size allowed. In the native case, we return 0xffffffff to indicate that the buffer size is unbounded (subject to memory availability), in the virtual case we return the size of the mempool. Also collapse native init_cyclestats functions to a single version, as each chip had identical versions of the code.

* gpu: nvgpu: Direct GMMU PTE kind controlSami Kiminki2017-09-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allow userspace to control directly the PTE kind for the mappings by supplying NVGPU_AS_MAP_BUFFER_FLAGS_DIRECT_KIND_CTRL for MAP_BUFFER_EX. In particular, in this mode, the userspace will tell the kernel whether the kind is compressible, and if so, what is the incompressible fallback kind. By supplying only the compressible kind, the userspace can require that the map kind will not be demoted to the incompressible fallback kind in case of comptag allocation failure. Add also a GPU characteristics flag NVGPU_GPU_FLAGS_SUPPORT_MAP_DIRECT_KIND_CTRL to signal whether direct kind control is supported. Fix indentation of nvgpu_as_map_buffer_ex_args header comment.

| | | | | | | | | | | | | | | | | | | | | | | | In order to perform timestamps correlation for FECS traces, we need to collect GPU / GPU timestamps samples. In virtualization case, it is possible for a guest to get GPU timestamps by using read_ptimer. However, if the CPU timestamp is read on guest side, and the GPU timestamp is read on vm-server side, then it introduces some latency that will create an artificial offset for GPU timestamps (~2 us in average). For better CPU / GPU timestamps correlation, Added a command to collect all timestamps on vm-server side.

* 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.
