nvs worker thread is created on each resume and deinitialized on every suspend. nvgpu can be resumed when process is getting killed. Thread creation can fail when the process is getting killed. That will lead to driver resume failure. To avoid the issue above, don't stop the nvs worker thread in suspend and let the first created thread handle the nvs work always. Deinitialize the nvs worker thread during nvgpu unload. Also, log the error returned by nvgpu_thread_create in the function nvgpu_worker_start. bug 3480192 Change-Id: I8d5d9e7716a950b162cc3c2d9fcfde07c4edfcf6 Signed-off-by: Sagar Kamble <skamble@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/c/linux-nvgpu/+/2646218 Tested-by: mobile promotions <svcmobile_promotions@nvidia.com> Reviewed-by: svcacv <svcacv@nvidia.com> Reviewed-by: svc-mobile-coverity <svc-mobile-coverity@nvidia.com> Reviewed-by: svc-mobile-misra <svc-mobile-misra@nvidia.com> Reviewed-by: svc-mobile-cert <svc-mobile-cert@nvidia.com> Reviewed-by: Vijayakumar Subbu <vsubbu@nvidia.com> Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> GVS: Gerrit_Virtual_Submit
