Add a new dlfilter to show cycles. Cycle counts are accumulated per CPU (or per thread if CPU is not recorded) from IPC information, and printed together with the change since the last print, at the start of each line. Separate counts are kept for branches, instructions or other events. Note also, the itrace A option can be useful to provide higher granularity cycle information. Example: $ perf record -e intel_pt/cyc/u uname Linux [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.044 MB perf.data ] $ perf script --itrace=A --call-trace --dlfilter dlfilter-show-cycles.so --deltatime | head 0 perf-exec 8509 [001] 0.000000000: psb offs: 0 0 perf-exec 8509 [001] 0.000000000: cbr: 42 freq: 4219 MHz (156%) 833 833 uname 8509 [001] 0.000047689: (/usr/lib/x86_64-linux-gnu/ld-2.31.so ) _start 833 uname 8509 [001] 0.000003261: (/usr/lib/x86_64-linux-gnu/ld-2.31.so ) _dl_start 2015 1182 uname 8509 [001] 0.000000282: (/usr/lib/x86_64-linux-gnu/ld-2.31.so ) _dl_start 2676 661 uname 8509 [001] 0.000002629: (/usr/lib/x86_64-linux-gnu/ld-2.31.so ) _dl_start 3612 936 uname 8509 [001] 0.000001232: (/usr/lib/x86_64-linux-gnu/ld-2.31.so ) _dl_start 4579 967 uname 8509 [001] 0.000002519: (/usr/lib/x86_64-linux-gnu/ld-2.31.so ) _dl_start 6145 1566 uname 8509 [001] 0.000001050: (/usr/lib/x86_64-linux-gnu/ld-2.31.so ) _dl_setup_hash 6239 94 uname 8509 [001] 0.000000023: (/usr/lib/x86_64-linux-gnu/ld-2.31.so ) _dl_sysdep_start Reviewed-by:Andi Kleen <ak@linux.intel.com> Signed-off-by:

Normally, for cycle-acccurate mode, IPC values are an exact number of instructions and cycles. Due to the granularity of timestamps, that happens only when a CYC packet correlates to the event. Support the itrace 'A' option, to use instead, the number of cycles associated with the current timestamp. This provides IPC information for every change of timestamp, but at the expense of accuracy. Due to the granularity of timestamps, the actual number of cycles increases even though the cycles reported does not. The number of instructions is known, but if IPC is reported, cycles can be too low and so IPC is too high. Note that inaccuracy decreases as the period of sampling increases i.e. if the number of cycles is too low by a small amount, that becomes less significant if the number of cycles is large. Furthermore, it can be used in conjunction with dlfilter-show-cycles.so to provide higher granularity cycle information. Reviewed-by:

Commit 11086054 ("mm/secretmem: use refcount_t instead of atomic_t") attempted to fix the problem of secretmem_users wrapping to zero and allowing suspend once again. But it was reverted in commit 87066fdd ("Revert 'mm/secretmem: use refcount_t instead of atomic_t'") because of the problems it caused - a refcount_t was not semantically the right type to use. Instead prevent secretmem_users from wrapping to zero by forbidding new users if the number of users has wrapped from positive to negative. This stops a long way short of reaching the necessary 4 billion users where it wraps to zero again, so there's no need to be clever with special anti-wrap types or checking the return value from atomic_inc().

Commit efafec27 ("spi: Fix tegra20 build with CONFIG_PM=n") already fixed the build without PM support once. There was an alternative fix by Guenter in commit 2bab9409 ("spi: tegra20-slink: Declare runtime suspend and resume functions conditionally"), and Mark then merged the two correctly in ffb1e76f ("Merge tag 'v5.15-rc2' into spi-5.15"). But for some inexplicable reason, Mark then merged things _again_ in commit 59c4e190 ("Merge tag 'v5.15-rc3' into spi-5.15"), and screwed things up at that point, and the __maybe_unused attribute on tegra_slink_runtime_resume() went missing. Reinstate it, so that alpha (and other architectures without PM support) builds cleanly again. Btw, this is another prime example of how random back-merges are not good. Just don't do them. Subsystem developers should not merge my tree in any normal circumstances. Both of those merge commits pointed to above are bad: even the one that got the merge result right doesn't even mention _why_ it was done, and the one that got it wrong is obviously broken.

Because _LARGEFILE64_SOURCE is set in perf, file offset sizes can be 64 bits. If a workflow needs to open /proc/kcore on a 32 bit system (for example to decode Arm ETM kernel trace) then the size value will be wrapped to 32 bits in the function file_size() at this line: dso->data.file_size = st.st_size; Setting the file_size member to be u64 fixes the issue and allows /proc/kcore to be opened.

During the process of driver probing, the probe function should return < 0 for failure, otherwise, the kernel will treat value > 0 as success.
