2023-03-27PM: tools: sleepgraph: Recognize "CPU killed" messagesXueqin Luo1-1/+4
On the arm64 platform with PSCI, the core log of CPU offline is as follows: [ 100.431501] CPU1: shutdown [ 100.454820] psci: CPU1 killed (polled 20 ms) [ 100.459266] CPU2: shutdown [ 100.482575] psci: CPU2 killed (polled 20 ms) [ 100.486057] CPU3: shutdown [ 100.513974] psci: CPU3 killed (polled 28 ms) [ 100.518068] CPU4: shutdown [ 100.541481] psci: CPU4 killed (polled 24 ms) Prevent sleepgraph from mistakenly treating the "CPU up" message as part of the suspend flow (because it should be regarded as part of the resume flow) by making it recognize the "CPU* killed" messages above.

2023-03-27pm-graph: Update to v5.11Todd Brandt3-18/+75
install_latest_from_github.sh: - Added a new script which allows users to install the latest pm-graph from the upstream github repo. This is useful if the kernel source version has issues that have already been fixed in github. sleepgraph.py: - Updated all the dmesg suspend/resume PM print formats to be able to process recent timelines using dmesg only. - Added ethtool output to the log for the system's ethernet device id the ethtool exists. This helps in debugging network issues. - Made the tool more robustly handle events where mangled dmesg or ftrace outputs do not include all the requisite data. The tool fails gracefully instead of creating a garbled timeline. Signed-off-by: Todd Brandt <[email protected]> [ rjw: Changelog edits ] Signed-off-by: Rafael J. Wysocki <[email protected]>
2023-03-27tools: ynl: default to treating enums as flags for mask generationJakub Kicinski2-5/+6
I was a bit too optimistic in commit bf51d27704c9 ("tools: ynl: fix get_mask utility routine"), not every mask we use is necessarily coming from an enum of type "flags". We also allow flipping an enum into flags on per-attribute basis. That's done by the 'enum-as-flags' property of an attribute. Restore this functionality, it's not currently used by any in-tree family. Signed-off-by: Jakub Kicinski <[email protected]> Signed-off-by: David S. Miller <[email protected]>

While testing the tool I noticed we miss the u16 type on payload create. On the code inspection it turned out we miss also u64 - add them. We also miss the decoding of u16 despite the fact `NlAttr` class supports it - add it.

2023-03-25selftests/bpf: Tests execution support for test_loader.cEduard Zingerman2-14/+150
Extends test_loader.c:test_loader__run_subtests() by allowing to execute BPF_PROG_TEST_RUN bpf command for selected programs. This is similar to functionality provided by test_verifier. Adds the following new attributes controlling test_loader behavior: __retval(...) __retval_unpriv(...) * If any of these attributes is present, the annotated program would be executed using libbpf's bpf_prog_test_run_opts() function. * If __retval is present, the test run would be done for program loaded in privileged mode. * If __retval_unpriv is present, the test run would be done for program loaded in unprivileged mode. * To mimic test_verifier behavior, the actual run is initiated in privileged mode. * The value returned by a test run is compared against retval parameter. The retval attribute takes one of the following parameters: - a decimal number - a hexadecimal number (must start from '0x') - any of a three special literals (provided for compatibility with test_verifier): - INT_MIN - POINTER_VALUE - TEST_DATA_LEN An example of the attribute usage: SEC("socket") __description("return 42") __success __success_unpriv __retval(42) __naked void the_42_test(void) { asm volatile (" \ r0 = 42; \ exit; \ " ::: __clobber_all); } Signed-off-by: Eduard Zingerman <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Alexei Starovoitov <[email protected]>

Extends test_loader.c:test_loader__run_subtests() by allowing to execute tests in unprivileged mode, similar to test_verifier.c. Adds the following new attributes controlling test_loader behavior: __msg_unpriv __success_unpriv __failure_unpriv * If any of these attributes is present the test would be loaded in unprivileged mode. * If only "privileged" attributes are present the test would be loaded only in privileged mode. * If both "privileged" and "unprivileged" attributes are present the test would be loaded in both modes. * If test has to be executed in both modes, __msg(text) is specified and __msg_unpriv is not specified the behavior is the same as if __msg_unpriv(text) is specified. * For test filtering purposes the name of the program loaded in unprivileged mode is derived from the usual program name by adding `@unpriv' suffix. Also adds attribute '__description'. This attribute specifies text to be used instead of a program name for display and filtering purposes.
