[gentoo-user] DRM kernel issues

> OK,

So I built this kernel twice, one with DRM * and once DRM [m]

In the /boot dir ; diff config-3.13.6-gentoo config-3.13.6B-gentoo

yeilds:


2256,2257c2256,2257
< CONFIG_AGP=y
< CONFIG_AGP_AMD64=y
---
> CONFIG_AGP=m
> CONFIG_AGP_AMD64=m
2264,2265c2264,2265
< CONFIG_DRM=y
< CONFIG_DRM_KMS_HELPER=y
---
> CONFIG_DRM=m
> CONFIG_DRM_KMS_HELPER=m
2268c2268
< CONFIG_DRM_TTM=y
---
> CONFIG_DRM_TTM=m
2278c2278
< CONFIG_DRM_RADEON=y
---
> CONFIG_DRM_RADEON=m


So when I boot the one with DRM_Radeon=m, I still get this error
message building the latest radeon driver:

* Checking for suitable kernel configuration options...
(red) * CONFIG_DRM must be disabled or compiled as a module and not 
(red) * loaded for direct rendering to work.
 * Please check to make sure these options are set correctly.

Sure it can easily be related to my limited knowledge of grub2,
but I did boot the 3.13.6B version of the kernel....
where all is set as modules....

ideas or suggestions as to what I missed?

Doesn't the ebuild check the config in /usr/src/linux, not 
/proc/config.gz? So it is checking your latest config, not the running
kernel.

The build process builds against whatever was last built in /usr/src/linux.

That means that, even though you've booted a kernel that has DRM built as a
module, when ati-drivers builds, it is looking at the config and objects that
reside within /usr/src/linux.

That being said, I'm pretty sure the warning you're being presented with is
just a warning and is safe to ignore, given that you know you need to be
running a kernel that does not have DRM built-in.

Well this is good news too.... I suspected something like
this, but did not know....

Ah, look what I verified:

glxinfo
name of display: :0
display: :0  screen: 0
direct rendering: Yes


But compiling the driver still fails, despite making DRM[m]
as suggested:

make[1]: Leaving directory `/usr/src/linux-3.13.6B-gentoo'
make: *** [kmod_build] Error 2
 * ERROR: x11-drivers/ati-drivers-13.9::gentoo failed (compile phase):
 *   emake failed

menuconfig -->DD-->graphics-->

 <M> Direct Rendering Manager (XFree86 4.1.0 and higher DRI 
 <M> ATI Radeon       

Can you spot what I'm doing wrong?

Hey, thx Mick. This problem is related to my quandry of how to manage grub2
efficiently. It's likely to take me days/weeks to experiment and 
figure out what to do, exactly. I find interesting snippets about Grub 2
around the net, few well written documents. If rebooting is an 
unpredictable exercise, it makes kernel refinements and debugging
an event for lots of cursing; not that I curse machines (too much).....


I'll post back when I've made some progress (either forward or backward).

thx,
James

Well, I think I found the problem (?)

lspci shows:

[Radeon HD 4350/4550]    an old fanless  card in this FX8350 machine

This web pages shows only x11-org support for this card (?):
https://wiki.gentoo.org/wiki/ATI_FAQ

RV770 (R700) 	RadeonHD 4000 series 	[xorg]   
Note no "AMD" or "DRI"

equery depends ati-drivers
 * These packages depend on ati-drivers:
x11-base/xorg-drivers-1.14 (video_cards_fglrx ? x11-drivers/ati-drivers)


So I must make modification so the ati-drivers is not called by
xorg-drivers. The desktop is simple X with LXDE and openbox; so why is
ati-drivers being called by xorg-drivers? Because I have this set up in
make.conf (?):

VIDEO_CARDS="radeon fbdev fglrx vesa"

Which should be 
VIDEO_CARDS="fbdev fglrx vesa"

???
comments?

Yes, VIDEO_CARDS is a USE-Expand variable - each item in VIDEO_CARDS is
expanded to an equivalent use flag of "video_cards_<flag>", meaning
VIDEO_CARDS="radeon fbdev fglrx vesa" expands into:

video_cards_radeon
video_cards_fbdev
video_cards_fglrx
video_cards_vesa

These use flags then tell xorg-drivers to pull in the relevant packages.

Remove fglrx from your VIDEO_CARDS, do a world-update and depclean (and make
sure you check ``eselect opengl`` is set to "xorg-x11") and see how that goes.

Cheers.
