Hi,

I'm running kernel 2.4.0 on Redhat 7.0. I tried to get direct rendering running (it failed, but that's another story). Today I noticed something strange in /proc: dri appears there 4 times.

ls /proc:
...

-r--r--r--    1 root     root            0 Jan 16 08:57 dma
dr-xr-xr-x    3 root     root            0 Jan 16 08:57 dri
dr-xr-xr-x    3 root     root            0 Jan 16 08:57 dri
dr-xr-xr-x    3 root     root            0 Jan 16 08:57 dri
dr-xr-xr-x    3 root     root            0 Jan 16 08:57 dri
dr-xr-xr-x    2 root     root            0 Jan 16 08:57 driver

...

Chdir /proc/dri/0 works fine:

bobo:/proc/dri/0>ls
bufs clients histo mem name queues vm vma

No dri modules, everything is linked in (I know I don't need all of these, but I have lots of memory, so...).

...

CONFIG_AGP_INTEL=y

CONFIG_AGP_VIA=y

Hi Bobo,

To fix this just link in only the support that corresponds to your hardware. The design of dri is such that (one could paraphrase) each driver-specific part includes its own copy of what should be "driver-independent shared dri_core engine" (e.g. proc handling stuff).

Fixing this requires either a new filesystem type (drifs) or (simpler!) redesigning dri to separate common things into a separate dri_core thing shared amongst them.

Regards,
Tigran

Fixing this requires either a new filesystem type (drifs) or (simpler!) redesigning dri to separate common things into a separate dri_core thing shared amongst them.

just for completeness -- there is the 3rd option -- one could just fix the hack which is there (or was there half a year ago when I looked at it) which is supposed to detect that a file in /proc is already present. It is just not esthetically pleasant (good to eyes :) so I omitted this from the options...
