Subject: [PATCH v3 0/1] RAPL (Running Average Power Limit) driver
Date: Tue, 9 Apr 2013 05:46:17 -0700 [thread overview]
Message-ID: <1365511578-30453-1-git-send-email-jacob.jun.pan@linux.intel.com> (raw)
Changes since V3:
This is a simpler version which only exposes interface via
the generic thermal layer. No new ABI introduced.
RAPL driver does some automatic settings to the related power
parameters based on user's single input from thermal cooling
device interface.
On the other side, more work needed to fully use RAPL
interface. This is likely result in adding more knobs in the
generic thermal sysfs.
- deleted event notifications
- deleted per domain device and RAPL class and their private
sysfs
- added more logic to do some automatic settings based on
user input. e.g. will enable clamping by default and set
a reasonable time window for long term power limits.
Changes since V2:
- use 'struct device' instead of raw kobject to represent
RAPL domains
- changed eventfd control interface to use event string
instead of passing file descriptors that cannot be
authenticated in sysfs directory
- clean ups based on v1 reviews
- use kcalloc for arrays
- drop dependencies on X86
- misc cleanups
