Set timeout unit as usec in gr_gv11b_init_preemption_state. Used default timeout as 1msec and this timeout value can be modified through sysfs node: /sys/devices/gpu.0/gfxp_wfi_timeout_count For gp10b: gfxp_wfi_timeout_count is in syclk cycles For gv11b: gfxp_wfi_timeout_count is in usec Bug 2003668 Change-Id: I68d52ce996a83df90b8b3a8164debb07e5cb370f Signed-off-by: seshendra Gadagottu Reviewed-on: https://git-master.nvidia.com/r/1599658 Reviewed-by: mobile promotions Tested-by: mobile promotions --- drivers/gpu/nvgpu/gv11b/hal_gv11b.c | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) (limited to 'drivers/gpu/nvgpu/gv11b/hal_gv11b.c') diff --git a/drivers/gpu/nvgpu/gv11b/hal_gv11b.c b/drivers/gpu/nvgpu/gv11b/hal_gv11b.c index 5649d758..e6cf0e62 100644 --- a/drivers/gpu/nvgpu/gv11b/hal_gv11b.c +++ b/drivers/gpu/nvgpu/gv11b/hal_gv11b.c @@ -361,7 +361,7 @@ static const struct gpu_ops gv11b_ops = { .set_czf_bypass = NULL, .pre_process_sm_exception = gr_gv11b_pre_process_sm_exception, .set_preemption_buffer_va = gr_gv11b_set_preemption_buffer_va, - .init_preemption_state = NULL, + .init_preemption_state = gr_gv11b_init_preemption_state, .update_boosted_ctx = gr_gp10b_update_boosted_ctx, .set_bes_crop_debug3 = gr_gp10b_set_bes_crop_debug3, .create_gr_sysfs = gr_gv11b_create_sysfs, @@ -388,6 +388,10 @@ static const struct gpu_ops gv11b_ops = { gr_gv11b_handle_tpc_sm_ecc_exception, .decode_egpc_addr = gv11b_gr_decode_egpc_addr, .init_ctxsw_hdr_data = gr_gp10b_init_ctxsw_hdr_data, + .init_gfxp_wfi_timeout_count = + gr_gv11b_init_gfxp_wfi_timeout_count, + .get_max_gfxp_wfi_timeout_count = + gr_gv11b_get_max_gfxp_wfi_timeout_count, }, .fb = { .reset = gv11b_fb_reset, -- cgit v1.2.2
