- The user can disable KMS (per driver) by adding the a line options <drivername> modeset=0 to /etc/modprobe.d/options - ATI (as an example) can simply ship a file containing the line blacklist radeon and dump it into /etc/modprobe.d/ to prevent loading the radeon driver. rerunning mkinitrd will generate a new initrd without the radeon module.
YaST or the ATI installer could just dump the options or blacklist in its own file in /etc/modprobe.d. The "options" file isn't special. modprobe reads them all.
Definitely. I was going to write ATI could use the file fglrx.conf.
Yep, that'd be perfect.
The reason why I (and probably you) think that this might be useful is that SaX2 used to maintain per device ID lists of driver options. kernel developer might have a different take on that.
Yeah, it's probably possible to do it per-device, but right now the code doesn't support it. It's a driver-global option.
A per device blacklist would require modprobe to look at the alias list in the driver, match it against the hardware on the system and then apply the result to the blacklist. To make it general it would have to be usable for all sorts of device IDs. If we need it and the kernel people would accept such a feature (Jeff, your reply is very encouraging) I would actually implement this.
Well here's where it gets tricky. modprobe can still only pass global driver options. I suppose it would be possible to pass a blacklist=<alias> or something to work around that, but that's not what I had in mind. It could also be handled via writing to a sysfs file. All drivers support an unbind option, too. This isn't really a discussion to be had with me on this list, though. I'm not at all involved with the DRM drivers. - -Jeff - -- Jeff Mahoney SUSE Labs -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.12 (GNU/Linux) Comment: Using GnuPG with SUSE - http://enigmail.mozdev.org/ iEYEARECAAYFAksZZs0ACgkQLPWxlyuTD7IptwCgqFaxm94cDqQoic/hv8o78WZB 1C8An3j6DmTnKdQ50hMGh6xuTFDOWvdt =mag+ -----END PGP SIGNATURE----- -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org
