2023-03-27selftests/bpf: Don't assume page size is 4096Hengqi Chen1-1/+1
The verifier test creates BPF ringbuf maps using hard-coded 4096 as max_entries. Some tests will fail if the page size of the running kernel is not 4096. Use getpagesize() instead.

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 <todd.e.brandt@intel.com> [ rjw: Changelog edits ] Signed-off-by: Rafael J.

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 <kuba@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>

2023-03-27tools: ynl: Add missing types to encode/decodeMichal Michalik1-0/+6
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.
