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/gp10b/hal_gp10b.c | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'drivers/gpu/nvgpu/gp10b/hal_gp10b.c') diff --git a/drivers/gpu/nvgpu/gp10b/hal_gp10b.c b/drivers/gpu/nvgpu/gp10b/hal_gp10b.c index f13c2735..5ae6b638 100644 --- a/drivers/gpu/nvgpu/gp10b/hal_gp10b.c +++ b/drivers/gpu/nvgpu/gp10b/hal_gp10b.c @@ -332,6 +332,10 @@ static const struct gpu_ops gp10b_ops = { .create_gr_sysfs = gr_gp10b_create_sysfs, .set_ctxsw_preemption_mode = gr_gp10b_set_ctxsw_preemption_mode, .init_ctxsw_hdr_data = gr_gp10b_init_ctxsw_hdr_data, + .init_gfxp_wfi_timeout_count = + gr_gp10b_init_gfxp_wfi_timeout_count, + .get_max_gfxp_wfi_timeout_count = + gr_gp10b_get_max_gfxp_wfi_timeout_count, }, .fb = { .reset = fb_gk20a_reset, -- cgit v1.2.2
