drivers/base: cacheinfo: fix annoying typo when DT nodes are absent

2015-05-24T19:31:33Z

s/hierarcy/hierarchy/ Maybe the typo will annoy people enough so that they add the missing nodes to their device-tree files, but I still think this is better off fixed. Signed-off-by: Will Deacon Acked-by: Sudeep Holla Signed-off-by: Greg Kroah-Hartman

drivers: base: support cpu cache information interface to userspace via sysfs

2014-11-07T19:45:00Z

This patch adds initial support for providing processor cache information to userspace through sysfs interface. This is based on already existing implementations(x86, ia64, s390 and powerpc) and hence the interface is intended to be fully compatible. The main purpose of this generic support is to avoid further code duplication to support new architectures and also to unify all the existing different implementations. This implementation maintains the hierarchy of cache objects which reflects the system's cache topology. Cache devices are instantiated as needed as CPUs come online. The cache information is replicated per-cpu even if they are shared. A per-cpu array of cache information maintained is used mainly for sysfs-related book keeping. It also implements the shared_cpu_map attribute, which is essential for enabling both kernel and user-space to discover the system's overall cache topology. This patch also add the missing ABI documentation for the cacheinfo sysfs interface already, which is well defined and widely used.

cpufreq: Make linux-pm@vger.kernel.org official mailing list

2014-04-30T23:15:32Z

There has been confusion all the time about which mailing list to follow for cpufreq activities, linux-pm@vger.kernel.org or cpufreq@vger.kernel.org. Since patches sent to cpufreq@vger.kernel.org don't go to Patchwork which is a maintenance workflow problem, make linux-pm@vger.kernel.org the official mailing list for cpufreq stuff and remove all references of cpufreq@vger.kernel.org from kernel source. Later, we can request that the list be dropped entirely. Signed-off-by: Viresh Kumar [rjw: Changelog] Signed-off-by: Rafael J. Wysocki

acpi-cpufreq: Add new sysfs attribute freqdomain_cpus

2013-06-27T19:51:09Z

Commits fcf8058 (cpufreq: Simplify cpufreq_add_dev()) and aa77a52 (cpufreq: acpi-cpufreq: Don't set policy->related_cpus from .init()) changed the contents of the "related_cpus" sysfs attribute on systems where acpi-cpufreq is used and user space can't get the list of CPUs which are in the same hardware coordination CPU domain (provided by the ACPI AML method _PSD) via "related_cpus" any more. To make up for that loss add a new sysfs attribute "freqdomian_cpus" for the acpi-cpufreq driver which exposes the list of CPUs in the same domain regardless of whether it is coordinated by hardware or software.

acpi-cpufreq: Add support for disabling dynamic overclocking

2012-09-09T20:05:12Z

One feature present in powernow-k8 that isn't present in acpi-cpufreq is support for enabling or disabling AMD's core performance boost technology. This patch adds support to acpi-cpufreq, but also includes support for Intel's dynamic acceleration. The original boost disabling sysfs file was per CPU, but acted globally. Also the naming (cpb) was at least not intuitive. So lets introduce a single file simply called "boost", which sits once in /sys/devices/system/cpu/cpufreq. This should be the only way of using this feature, so add documentation about the rationale and the usage. A following patch will re-introduce the cpb knob for compatibility reasons on AMD CPUs. Per-CPU boost switching is possible, but not trivial and is thus postponed to a later patch series. Signed-off-by: Andre Przywara Signed-off-by: Rafael J. Wysocki
