> > you would just let it boot with default. Then in a script: > echo mode >/sys/class/drm/card0/agpmode Can we change the AGP mode dynamically at the moment, i.e. if I set it to 1 for default (because anything higher might not work) can I change it later if I've already initialised the AGP layer.. at the moment we don't init that AGP layer until X tells us to..

Yeah a sysfs sounds okay to me, but make sure that we don't go setting AGP at driver load, otherwise you havea chicken and egg issue where users can't change it because it is already started, and machine crashes on bootup .. An issue with doing all this on bootup is I can see very long kernel command lines appearing, which is something I don't really want to have to tell ppl, editing /etc/display.conf is a lot easier than say add "radeon:agp_mode=4" to everyones command line..

I'm trying to make the Xegl server not need root to run and I am trying to make it work without config files. So when something like AGP mode comes up I try to decide what module best has the information needed to set the parameter correctly. In this case it's clearly the DRM module - the ATI kernel driver even contains tweaks for specific card/motherboard pairs at 8X. The DRM module may also have multiple users, it not right for the start of Xegl to stomp the AGP mode of another user. This implies that the correct place for AGP mode setting is an attribute on the DRM driver. Of course we'll leave drmAgpEnable() in place. I'm just going to remove the UI code from the Xegl server for getting and setting an override. This also means I have to add the sysfs attribute to the DRM drivers. -- Jon Smirl [EMAIL PROTECTED] --- This SF.Net email is sponsored by: NEC IT Guy Games. How far can you shotput a projector?

Re: agp mode and egl
probably, but all the other drivers handle it in userspace, so consistency was the idea I guess. That doesn't mean we can't change things...

agp mode and egl
AGP mode is getting set form user space. Shouldn't this be a sysfs attribute for the DRM driver? The driver could then default to highest mode it thinks will work and a script can be used to override it if needed. -- Jon Smirl [EMAIL PROTECTED] --- This SF.Net email is sponsored by: NEC IT Guy Games.
