* gpu: nvgpu: hal for timestamps correlationThomas Fleury2017-06-15
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* gpu: nvgpu: Begin removing variables in struct gk20aAlex Waterman2017-05-30
| | | | | | | | | | | | | | | | | | | | | | Begin removing all of the myriad flag variables in struct gk20a and replace that with one API that checks for flags being enabled or disabled. The API is as follows: bool nvgpu_is_enabled(struct gk20a *g, int flag); bool __nvgpu_set_enabled(struct gk20a *g, int flag, bool state); These APIs allow many of the gk20a flags to be replaced by defines. This makes flag usage consistent and saves a small amount of memory in struct gk20a. Also it makes struct gk20a easier to read since there's less clutter scattered through out.

| | | | | | | | | | | | | | | | | | | | | | Split handling of stalling interrupt to Linux specific chip agnostic and OS independent chip specific parts. Linux specific chip independent part contains handler for ISR and passing the control to a bottom half. It uses the new MC HALs intr_stall (query interrupt status), intr_pause (pause interrupts) and intr_resume (resume interrupts). MC HAL isr_stall now returns void and gets called in thread context and thus remove isr_thread_stall and replace the implementation with isr_stall.

* gpu: nvgpu: Add and use VM init/deinit APIsAlex Waterman2017-05-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove the VM init/de-init from the HAL and instead use a single set of routines that init/de-init VMs. This prevents code divergence between vGPUs and regular GPUs. This patch also clears up the naming of the routines a little bit. Since some VMs are used inplace and others are dynamically allocated the APIs for freeing them were confusing. Also some free calls also clean up an instance block (this is API abuse - but this is how it currently exists). The new API looks like this: void __nvgpu_vm_remove(struct vm_gk20a *vm); void nvgpu_vm_remove(struct vm_gk20a *vm); void nvgpu_vm_remove_inst(struct vm_gk20a *vm, struct nvgpu_mem *inst_block); void nvgpu_vm_remove_vgpu(struct vm_gk20a *vm); int nvgpu_init_vm(struct mm_gk20a *mm, struct vm_gk20a *vm, u32 big_page_size, u64 low_hole, u64 kernel_reserved, u64 aperture_size, bool big_pages, bool userspace_managed, char *name); void nvgpu_deinit_vm(struct vm_gk20a *vm); JIRA NVGPU-12 JIRA NVGPU-30 Change-Id: Ia4016384c54746bfbcaa4bdd0d29d03d5d7f7f1b Signed-off-by: Alex Waterman <alexw@nvidia.com> Reviewed-on: http://git-master/r/1477747 Reviewed-by: Automatic_Commit_Validation_User GVS: Gerrit_Virtual_Submit Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com>
