perf-help(1) ============ NAME ---- perf-help - display help information about perf SYNOPSIS -------- 'perf help' [-a|--all] [COMMAND] DESCRIPTION ----------- With no options and no COMMAND given, the synopsis of the 'perf' command and a list of the most commonly used perf commands are printed on the standard output. If the option '--all' or '-a' is given, then all available commands are printed on the standard output. If a perf command is named, a manual page for that command is brought up. The 'man' program is used by default for this purpose, but this can be overridden by other options or configuration variables. Note that `perf --help ...` is identical to `perf help ...` because the former is internally converted into the latter. OPTIONS ------- -a:: --all:: Prints all the available commands on the standard output. This option supersedes any other option. PERF ---- Part of the linkperf:perf[1] suite ='hidden' name='id' value='047487241ff59374fded8c477f21453681f5995c'/> net-next plumbingsTobias Klauser

sparc64: Handle PIO & MEM non-resumable errors.
User processes trying to access an invalid memory address via PIO will receive a SIGBUS signal instead of causing a panic. Memory errors will receive a SIGKILL since a SIGBUS may result in a coredump which may attempt to repeat the faulting access. Signed-off-by: Liam R.
