perf(1) ======= NAME ---- perf - Performance analysis tools for Linux SYNOPSIS -------- [verse] 'perf' [--version] [--help] [OPTIONS] COMMAND [ARGS] OPTIONS ------- --debug:: Setup debug variable (see list below) in value range (0, 10). Use like: --debug verbose # sets verbose = 1 --debug verbose=2 # sets verbose = 2 List of debug variables allowed to set: verbose - general debug messages ordered-events - ordered events object debug messages data-convert - data convert command debug messages --buildid-dir:: Setup buildid cache directory. It has higher priority than buildid.dir config file option. -v:: --version:: Display perf version. -h:: --help:: Run perf help command. DESCRIPTION ----------- Performance counters for Linux are a new kernel-based subsystem that provide a framework for all things performance analysis. It covers hardware level (CPU/PMU, Performance Monitoring Unit) features and software features (software counters, tracepoints) as well.

regulator: fixed: Revert support for ACPI interface
This reverts commit 13bed58ce874 (regulator: fixed: add support for ACPI interface). While there does appear to be a practical need to manage regulators on ACPI systems, using ad-hoc properties to describe regulators to the kernel presents a number of problems (especially should ACPI gain first class support for such things), and there are ongoing discussions as to how to manage this. Until there is a rough consensus, revert commit 13bed58ce8748d43, which hasn't been in a released kernel yet as discussed in [1] and the surrounding thread.
