linux-source-2.6.20 2.6.20-12.19 does not enable CONFIG_DEBUG_FS

Bug #93489 reported by Mark Carey on 2007-03-18
Affects Status Importance Assigned to Milestone
linux-source-2.6.20 (Ubuntu)

Bug Description

Binary package hint: linux-source-2.6.20

Download open in archive manager, open data.tar.gz, extract .config and grep for CONFIG_DEBUG_FS.

careys@jersey:~/Desktop$ cat .config | grep CONFIG_RELAY
careys@jersey:~/Desktop$ cat .config | grep CONFIG_DEBUG_FS
# CONFIG_DEBUG_FS is not set

Whys it this important, it is important for nouveau and renouveau devs trying to obtain mimo traces of nvidia graphics cards, refer renouveau will work from 6.06, however mimo tracing requires CONFIG_DEBUG_FS be set.

If this was enabled more ubuntu users would be able to assist the development of the nouveau driver in line with Mark Shuttleworths pledge of assistance to nouveau refer item 2.

Note that I am in no way oficially affiliated with the nouveau project, I just want to be able to help and seing as Fiesty will have a kernel with version greater than 2.6.19-rc1 this would be a great help to nouveau, myself and to others trying the same thing.

"...I discussed this with Ben Collins, who leads the kernel team in Ubuntu, who says:

    Yeah, I'll have it enabled for post-beta (which should mean it will be
    available in RC).

So, you’re in luck!..."

I have just downloaded the Fiesty Beta iso and can confirm that;

mark@daisy:/usr/src/linux-headers-2.6.20-12$ cat .config | grep CONFIG_DEBUG_FS
# CONFIG_DEBUG_FS is not set

Reviewing it appears that RC will be availiable on April 12th.
