           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.

Most pre-r6xx desktop cards, including yours, do not offer power saving states
in the power tables.  As such all power states are the same on your card.  auto
does nothing on your card as well since all it does is wait for for acpi power
plug events and switch between lower and higher power states when that happens.
 Since your system is a desktop, there is no acpi power plug event.
