* gpu: nvgpu: Move priv_ring HAL to commonTerje Bergstrom2018-08-13
| | | | | | | | | | | | | | | | | Move implementation of priv_ring HAL to common/priv_ring. Implement two new HAL APIs to remove illegal dependencies: enable_priv_ring and enum_ltc. As enum_ltc can be implemented only gm20b onwards, bump gk20a implementation to base on gm20b.

* gk20a: nvgpu: Remove io.h dependency from gk20a.hDebarshi Dutta2018-07-30
| | | | | | | | | | | | | | | | In the current code, gk20a.h includes io.h which gets directly included in a lot of other files. io.h contains methods which uses a struct gk20a as a parameter leading to a circular dependency between io.h and gk20a.h. This can be mitigated by removing io.h from gk20a.h as part of larger effort to moving gk20a.h to nvgpu/gk20a.h JIRA NVGPU-597 Change-Id: I93e504fa9371b88152737b342a75580c65e8f712 Signed-off-by: Debarshi Dutta <ddutta@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/1787316 Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>

* gpu: nvgpu: Fixups for tmake buildAlex Waterman2018-05-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Mostly just including necessary includes to make sure that global function declarations actually match their implementations. Also work around pointer munging warning: /build/ddpx/linux/kernel/nvgpu/drivers/gpu/nvgpu/common/pmu/pmu.c: In function 'nvgpu_pmu_process_init_msg': /build/ddpx/linux/kernel/nvgpu/drivers/gpu/nvgpu/common/pmu/pmu.c:348:4: error: dereferencing type-punned pointer will break strict-aliasing rules [-Werror=strict-aliasing] (*(u32 *)gid_data.signature == PMU_SHA1_GID_SIGNATURE); Work around this warning by simply moving the type punning. This code is certainly dangerous - it assumes the endianness of the header data is the same as the machine this code is running on. Apparently it works, though, so this ignores the warning.

* gpu: nvgpu: fix priv error register readsThomas Fleury2018-03-28
| | | | | | | | | | | | | | | | | | | | | | | | Current code does not compute priv error register offsets properly. This leads to invalid decoding of priv errors, and can also trigger additional priv errors. - add GPU_LIT_GPC_PRIV_STRIDE define - return proj_gpc_priv_stride for GPU_LIT_GPC_PRIV_STRIDE in hals - use GPU_LIT_GPC_PRIV_STRIDE instead of GPU_LIT_GPC_STRIDE in g->ops.priv_ring.isr() to compute priv error register offsets.

* 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.
