Basic units like fifo, rc are having dependency on gr_falcon. Avoided outside gr units dependency on gr_falcon by moving following functions to gr: int nvgpu_gr_falcon_disable_ctxsw(struct gk20a *g, struct nvgpu_gr_falcon *falcon); -> int nvgpu_gr_disable_ctxsw(struct gk20a *g); int nvgpu_gr_falcon_enable_ctxsw(struct gk20a *g, struct nvgpu_gr_falcon *falcon); -> int nvgpu_gr_enable_ctxsw(struct gk20a *g); int nvgpu_gr_falcon_halt_pipe(struct gk20a *g); -> int nvgpu_gr_halt_pipe(struct gk20a *g); HALs also moved accordingly and updated code to reflect this. Also moved following data back to gr from gr_falcon: struct nvgpu_mutex ctxsw_disable_mutex; int ctxsw_disable_count; JIRA NVGPU-3168 Change-Id: I2bdd4a646b6f87df4c835638fc83c061acf4051e Signed-off-by: Seshendra Gadagottu <sgadagottu@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/2100009 Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>
