Subject: [Bug 94061] New: [radeon - Kaveri] dpm works badly - much to high power consumption compared to catalyst
Date: Sun, 01 Mar 2015 12:26:19 +0000 [thread overview]
Message-ID: <bug-94061-2300@https.bugzilla.kernel.org/> (raw)
https://bugzilla.kernel.org/show_bug.cgi?id=94061
Bug ID: 94061
Summary: [radeon - Kaveri] dpm works badly - much to high power
consumption compared to catalyst
Product: Drivers
Version: 2.5
Kernel Version: 3.14.x ... 3.19.
Hardware: All
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Video(DRI - non Intel)
Assignee: drivers_video-dri@kernel-bugs.osdl.org
Reporter: abcdmail@freenet.de
Regression: No
With all kernel versions >= 3.14 (I didn't test versions below), radeon / dpm
consumes about 6 W more compared to catalyst in idle mode (X-server 1.15 /
1.16) with Kaveri graphics (AMD A10-7800 Radeon R7).
Idle mode: Xorg runs (KDE 4.11.x), screen saver off, static screen, load: 0.0
If the screen is turned off by X, the power consumption finally reaches the
same level as with catalyst. It's raising immediately again at the moment the
screen is switched on again by X.
Seams the lowest rate is never reached as long as even a static screen has to
be drawn - but it should!
