Subject: [Bug 28522] New: power_profile auto consumes more power than power_profile high
Date: Sun, 13 Jun 2010 05:24:52 -0700 (PDT) [thread overview]
Message-ID: <bug-28522-502@http.bugs.freedesktop.org/> (raw)
https://bugs.freedesktop.org/show_bug.cgi?id=28522
Summary: power_profile auto consumes more power than
power_profile high
Product: DRI
Version: unspecified
Platform: x86-64 (AMD64)
OS/Version: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: DRM/Radeon
AssignedTo: dri-devel@lists.freedesktop.org
ReportedBy: Henning.Fleddermann@gmx.net
Created an attachment (id=36247)
--> (https://bugs.freedesktop.org/attachment.cgi?id=36247)
my x1900xt's bios
Kernel 2.6.35-rc3, Xorg-Server 1.8.1, xf86-video-ati 6.13.0
For some weird reason my system consumes ~15W more when I set the power_profile
to auto, compared to all other power-profiles (low, default and high all
consume the same amount of power). I measured this with a powermeter.
"cat /debug/dri/0/radeon_pm_info" always says:
default engine clock: 500000 kHz
current engine clock: 499500 kHz
default memory clock: 600000 kHz
current memory clock: 594000 kHz
PCIE lanes: 0
No matter which power_profile I select.
My card is a ATi X1900XT. dileX_ on #radeon suggested that I attach my
video-card bios, so I'll do that.
