Date: Sun, 28 Jan 2018 10:48:41 +0000 [thread overview]
Message-ID: <bug-198601-137361@https.bugzilla.kernel.org/> (raw)
https://bugzilla.kernel.org/show_bug.cgi?id=198601
Bug ID: 198601
Summary: Conservative governor is broken in 4.14.14
Product: Power Management
Version: 2.5
Kernel Version: 4.14.14
Hardware: IA-64
OS: Linux
Tree: Mainline
Status: NEW
Severity: blocking
Priority: P1
Component: cpufreq
Assignee: linux-pm@vger.kernel.org
Reporter: t.artem@mailcity.com
Regression: No
This is happening under Intel Core i5 2500. I'm running a single instance of
the `flac` utility (which has now been running for 10 minutes already).
Under the ondemand governor:
3986.1MHz
4058.03MHz
3847.3MHz
3929.33MHz
Under the conservative governor:
1700.09MHz
1700.09MHz
1700.15MHz
1700.1MHz
For some reasons the conservative governor refuses to increase CPU cores
frequencies above 1700MHz. I'm _not_ using Intel's pstate driver:
