2024-06-21rtla/osnoise: Better report when histogram is emptyLuis Claudio R. Goncalves1-0/+15
When osnoise hist does not observe any samples above the threshold, no entries are recorded and the final report shows empty entries for the usual statistics (count, min, max, avg): [~]# osnoise hist -d 5s -T 500 # RTLA osnoise histogram # Time unit is microseconds (us) # Duration: 0 00:00:05 Index over: count: min: avg: max: That could lead users to confusing interpretations of the results. A simple solution is to report 0 for count and the statistics, making it clear that no noise (above the defined threshold) was observed: [~]# osnoise hist -d 5s -T 500 # RTLA osnoise histogram # Time unit is microseconds (us) # Duration: 0 00:00:05 Index over: 0 count: 0 min: 0 avg: 0 max: 0 Link: https://lkml.kernel.org/r/[email protected] Cc: Daniel Bristot de Oliveira <[email protected]> Cc: John Kacur <[email protected]> Cc: Clark Williams <[email protected]> Reviewed-by: John Kacur <[email protected]> Signed-off-by: Luis Claudio R.

2024-06-21rtla/osnoise: Use pretty formatting only on interactive ttyLuis Claudio R. Goncalves1-4/+15
osnoise top performs background/font color formatting that could make the text output confusing if not on a terminal. Use the changes from commit f5c0cdad6684a ("rtla/timerlat: Use pretty formatting only on interactive tty") as an inspiration to fix this problem. Apply the formatting only if running on a tty, and not in quiet mode.

In test_bpf_ip_check_defrag_ok(), the new helper client_socket() can be used to replace connect_to_fd_opts() with "noconnect" opts, and the strcut member "noconnect" of network_helper_opts can be dropped now, always connect to server in connect_to_fd_opts().

2024-06-20selftests/bpf: Add client_socket helperGeliang Tang2-8/+31
This patch extracts a new helper client_socket() from connect_to_fd_opts() to create the client socket, but don't connect to the server. Then connect_to_fd_opts() can be implemented using client_socket() and connect_fd_to_addr(). This helper can be used in connect_to_addr() too, and make "noconnect" opts useless.

This patch moves "post_socket_cb" and "noconnect" into connect_to_addr(), then connect_to_fd_opts() can be implemented by getsockname() and connect_to_addr().

2024-06-20selftests/bpf: Drop type from network_helper_optsGeliang Tang5-33/+26
The opts.{type, noconnect} is at least a bit non intuitive or unnecessary. The only use case now is in test_bpf_ip_check_defrag_ok which ends up bypassing most (or at least some) of the connect_to_fd_opts() logic. It's much better that test should have its own connect_to_fd_opts() instead. This patch adds a new "type" parameter for connect_to_fd_opts(), then opts->type and getsockopt(SO_TYPE) can be replaced by "type" parameter in it. In connect_to_fd(), use getsockopt(SO_TYPE) to get "type" value and pass it to connect_to_fd_opts(). In bpf_tcp_ca.c and cgroup_v1v2.c, "SOCK_STREAM" types are passed to connect_to_fd_opts(), and in ip_check_defrag.c, different types "SOCK_RAW" and "SOCK_DGRAM" are passed to it. With these changes, the strcut member "type" of network_helper_opts can be dropped now.

Introduce a new 'of-fullname-regex' property that takes a regular expression and matches against the OF_FULLNAME property. It allows matching controllers that don't have a unique DT address across sibling controllers, and thus dt-mmio can't be used. One particular example of where this is needed is on MT8195 which has multiple USB controllers described by two level deep nodes and using the ranges property: ssusb2: usb@112a1000 { reg = <0 0x112a1000 0 0x2dff>, <0 0x112a3e00 0 0x0100>; ranges = <0 0 0 0x112a0000 0 0x3f00>; xhci2: usb@0 { Signed-off-by: Nícolas F.
