--- Comment #5 from vindica...@live.com --- At long last, I've got something to show. It's been a problem for a long time, but either I didn't have the instructions in my notes at the time or I just didn't have time or want to deal with it. When I ran "perf report", perf ended up hanging on "processing events". More time passed and I finally decided to look into that problem. Seems perf may have a bug now: https://bugs.freedesktop.org/show_bug.cgi?id=97879#c26 So after learning some stuff (like getting the questionable fd from strace), I closed the fd which was "/dev/dri/renderD128" and "perf report" finished processing the events and showed the results. Does anyone know where I might want to submit a bug for perf (unless it's a video issue)? ***** Samples: 48K of event 'cycles:ppp', Event count (approx.): 36686319551 Children Self Command Shared Object Symbol ◆ - 29.77% 0.00% kworker/0:1H [kernel.vmlinux] [k] kthread ▒ - kthread ▒ - 29.69% worker_thread ▒ - 26.62% process_one_work ▒ - 15.50% xs_tcp_setup_socket ▒ - 6.51% xs_create_sock ▒ - 3.35% __sock_create ▒ - 2.23% inet_create ▒ 0.92% sk_alloc ▒ - 0.71% tcp_v4_init_sock ▒ 0.63% tcp_init_sock ▒ - 0.82% sock_alloc ▒ - 0.69% new_inode_pseudo ▒ 0.65% alloc_inode ▒ - 2.24% xs_bind ▒ - kernel_bind ▒ - 2.03% inet_bind ▒ 0.86% inet_csk_get_port ▒ - 0.62% kernel_setsockopt ▒ 0.55% sock_setsockopt ▒ - 3.42% kernel_setsockopt ▒ - 2.49% sock_common_setsockopt ▒ - 2.41% tcp_setsockopt ▒ - 2.21% do_tcp_setsockopt.isra.6 ▒ 0.75% release_sock ▒ 0.58% sock_setsockopt ▒ - 1.40% xprt_force_disconnect ▒ - 1.07% rpc_wake_up_status ▒ 0.66% rpc_wake_up_task_on_wq_queue_locked.part.19 ▒ - 1.38% xprt_unlock_connect ▒ - 0.92% xs_tcp_release_xprt ▒ - 0.89% xprt_release_xprt ▒ - 0.83% xprt_clear_locked ▒ queue_work_on ▒ - 1.38% kernel_connect ▒ - 1.33% inet_stream_connect ▒ - 0.70% __inet_stream_connect ▒ 0.52% tcp_v4_connect ▒ - 10.00% xprt_autoclose ▒ - 8.85% xs_tcp_shutdown ▒ - 8.62% xs_reset_transport ▒ - 5.59% sock_release ▒ - 3.49% inet_release ▒ - 3.19% tcp_close ▒ - 1.22% inet_csk_destroy_sock ▒ 0.84% tcp_v4_destroy_sock ▒ - 0.63% sk_free ▒ 0.60% __sk_free ▒ - 1.93% iput ▒ - 1.61% evict ▒ - 0.89% destroy_inode ▒ 0.59% sock_destroy_inode ▒ - 2.20% kernel_sock_shutdown ▒ - 2.09% inet_shutdown ▒ - 1.35% xs_tcp_state_change ▒ 0.69% xprt_disconnect_done ▒ - 0.63% xs_tcp_release_xprt ▒ 0.54% xprt_release_xprt ▒ - 2.41% schedule ▒ - 2.26% __schedule ▒ - 1.08% deactivate_task ▒ - 0.83% dequeue_task_fair ▒ 0.67% dequeue_entity ▒ 0.57% pick_next_task_fair ▒ + 29.77% 0.00% kworker/0:1H [kernel.vmlinux] [k] ret_from_fork + 29.69% 0.33% kworker/0:1H [kernel.vmlinux] [k] worker_thread ▒ + 26.63% 0.48% kworker/0:1H [kernel.vmlinux] [k] process_one_work ▒ + 25.78% 0.00% kworker/1:1H [kernel.vmlinux] [k] kthread ▒ + 25.78% 0.00% kworker/1:1H [kernel.vmlinux] [k] ret_from_fork ▒ + 25.72% 0.27% kworker/1:1H [kernel.vmlinux] [k] worker_thread ▒ + 23.13% 0.49% kworker/1:1H [kernel.vmlinux] [k] process_one_work ▒ + 15.52% 0.72% kworker/0:1H [sunrpc] [k] xs_tcp_setup_socket ▒ + 13.55% 0.55% kworker/1:1H [sunrpc] [k] xs_tcp_setup_socket ▒ + 10.01% 0.17% kworker/0:1H [sunrpc] [k] xprt_autoclose ▒ + 9.37% 0.00% kworker/2:1H [kernel.vmlinux] [k] kthread ▒ + 9.37% 0.00% kworker/2:1H [kernel.vmlinux] [k] ret_from_fork ▒ + 9.34% 0.11% kworker/2:1H [kernel.vmlinux] [k] worker_thread ▒ + 8.87% 0.07% kworker/0:1H [sunrpc] [k] xs_tcp_shutdown ▒ + 8.62% 0.28% kworker/0:1H [sunrpc] [k] xs_reset_transport ▒ + 8.55% 0.15% kworker/1:1H [sunrpc] [k] xprt_autoclose ▒ + 8.35% 0.18% kworker/2:1H [kernel.vmlinux] [k] process_one_work ▒ + 7.70% 0.09% kworker/1:1H [sunrpc] [k] xs_tcp_shutdown ▒ + 7.44% 0.21% kworker/1:1H [sunrpc] [k] xs_reset_transport ▒ + 7.13% 0.00% plasmashell libc-2.24.so [.] __xstat64 ***** -- You are receiving this mail because: You are watching all bug changes.
