* gpu: nvgpu: move header location of gk20a.hDebarshi Dutta2018-09-25
| | | | | | | | | | | | | | | | | | | | | | | 1) Update header path of gk20a.h files present in os/ to <nvgpu/gk20a.h> 2) os_fence_android_sema.c indirectly was dependent on gk20a.h via semaphore.h. So, added #include <nvgpu/gk20a.h> in os_fence_android_sema.c and replaced the header with forward declaration of struct gk20a in semaphore.h Jira NVGPU-597 Change-Id: I96e23befeb80713f3a399071eb5498f6f580211d Signed-off-by: Debarshi Dutta <ddutta@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/1842868 Reviewed-by: svc-misra-checker <svc-misra-checker@nvidia.com> GVS: Gerrit_Virtual_Submit Reviewed-by: Konsta Holtta <kholtta@nvidia.com> Reviewed-by: Automatic_Commit_Validation_User Reviewed-by: Alex Waterman <alexw@nvidia.com> Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>
* gpu: nvgpu: debugfs node to enable/disable ltc_illegal_compstat intrseshendra Gadagottu2018-07-24
| | | | | | | | | | | | | | | | | | | Added debugfs node under ltc directory with name: intr_illegal_compstat_enable Enabling/disabling of ltc_illegal_compstat intr is possible through debugfs node. Since ltc state is lost with rail gate, this setting is cached and will be populated during ltc initialization.
