Re: [Mesa-dev] [RFC] add a config file for dri loader to choose a different dri driver
On my machine, the global drirc resides in /usr/etc/. I guess it's in a different place for each person. :) Marek On Tue, Jul 31, 2018 at 2:08 PM, Adam Jackson wrote: > On Tue, 2018-07-31 at 08:03 +, Yu, Qiang wrote: >> Seems the mesa driconf infrastructure is just what I need: >> https://dri.freedesktop.org/wiki/ConfigurationInfrastructure/ >> >> So I can reference the loader_get_dri_config_device_id implementation >> for adding loader driver override functionality in /etc/drirc: >> >> >> >> >> >> >> Thoughts? > > If you're going to go down this route, please also teach Mesa to look > for drirc (or drirc.d) under /usr/share first, then /etc. /etc really > is for per-machine configuration, Mesa and driver defaults properly > belong in /usr/share. > > - ajax > ___ > mesa-dev mailing list > mesa-dev@lists.freedesktop.org > https://lists.freedesktop.org/mailman/listinfo/mesa-dev ___ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev

I'm a fan of the full names - kernel_driver/dri_driver. There's plenty of inconsistencies in Mesa when using the shorthand "driver".

Re: [Mesa-dev] [RFC] add a config file for dri loader to choose a different dri driver
So you mean like the xorg way (priority low -> high): /usr/share/drirc.d/xxx.conf /etc/drirc.d/xxx.conf /etc/drirc ~/.drirc OK, I'll add this for the ease of driver config.

If you're going to go down this route, please also teach Mesa to look for drirc (or drirc.d) under /usr/share first, then /etc. /etc really is for per-machine configuration, Mesa and driver defaults properly belong in /usr/share. - ajax ___ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
Re: [Mesa-dev] [RFC] add a config file for dri loader to choose a different dri driver
Good idea. But adding a new device attribute seems over-kill, how about just use the driver attribute and prefix a "k:" for kernel driver like this: ?

Using the driconf infrastructure is definitely better than creating a new mechanism. It'll even allow configuring the driver per application. :) Grepping for device_id in src/util/xmlpool/t_options.h and src/loader/loader.c might be useful.

Re: [Mesa-dev] [RFC] add a config file for dri loader to choose a different dri driver
Seems the mesa driconf infrastructure is just what I need: https://dri.freedesktop.org/wiki/ConfigurationInfrastructure/ So I can reference the loader_get_dri_config_device_id implementation for adding loader driver override functionality in /etc/drirc: Thoughts?
