Description Didier G 2010-05-18 04:59:27 EDT

Description of problem:

radeon.dynpm parameter in kernel command line causes disable of KMS regardless value passed


Version-Release number of selected component (if applicable):

kernel-2.6.33.4-96.fc13.x86_64
xorg-x11-drv-ati-6.13.0-1.fc13.x86_64

01:00.0 VGA compatible controller: ATI Technologies Inc Juniper [Radeon HD 5700 Series]


Steps to Reproduce:
1. Just specify radeon.dynpm=0 or radeon.dynpm=1 in kernel command line
  
Actual results:

In /var/log/Xorg.0.Log and regardless value passed :

[     9.527] (II) [KMS] drm report modesetting isn't supported.
[     9.806] (II) RADEON(0): Dynamic Power Management Disabled


With *** NO *** radeon.dynpm in kernel command line :

[     9.835] (II) [KMS] Kernel modesetting enabled.



Expected results:

Dynamic Power Management if supported by hardware or warning message if not supported but KMS should stay enabled.

Comment 2 Jérôme Glisse 2010-05-18 11:24:53 EDT

My guess is that dynpm is unknown parameter and thus kernel refuse to load module (please provide dmesg with the parameter to verify this supposition). If that the case than there is nothing we can do, don't use this parameter.

Comment 3 Didier G 2010-05-18 14:22:45 EDT

In my configuration, according messages log :

May 18 11:00:43 lx-xxxxx kernel: radeon: Unknown parameter `dynpm' 

but according my understanding this option should enable power management (just google radeon.dynpm).

Comment 5 Jérôme Glisse 2010-05-18 15:19:38 EDT

This option doesn't apply to 2.6.33 (it might to 2.6.34) I am closing this as this isn't a bug. Just don't use parameter that are not valid.
