Hi,
when executing:
ACCEPT_KEYWORDS="~x86" emerge
/usr/portage/media-video/nvidia-kernel/nvidia-kernel-1.0.4349-r1.ebuild
the nvidia build script complains about missing MTRR support (obviously
a processor feature), which it says has to be build into the kernel. Ok,
did that - at least I tried, but to no avail.
Actually, there is no /proc/mtrr file (or link?) and I am not able to
generate one via nano or echo - it looks that I am not allowed to write
a simple file in /proc (insufficient access rights? Can't be, I am
logged on as root).
(BTW, I already found mtrr-related postings describing this behaviour
which unfortunately where not helpful in my case).
In /usr/src/linux/Documentation/mtrr.txt I find that there has to be a
CONFIG_MTRR Option (I assume it's a #DEFINE that is used somewhere in
C/C++ source via #IFDEF) which will take care of generating the
/proc/mtrr file (right?). Should'nt make menuconfig take care of this
setting? Or do I have to set this? If, then how and where?
Maybe this is the point where I should describe what I actually want to
acchieve:
After installing Gentoo the X Server won't run after startx (what
happens each and every year whenever I tried to install Linux and
finally gave up frustrated, beginning sometime arround 1996 :-/).
In the log the NVDriver complains about some bad settings, so this
*could* still be a simple (display) setting problem in the XFree86config
(what I doubt). So the good thing is, the NVDriver module is running (it
is, I checked via lsmod).
I thought I need to update to the newer driver version 4349 (what I am
able now after getting help of Jose G.G.). So there I am stuck, because
this update won't compile, it needs the MTRR kernel setting, which it
probably identifies by the /proc/mtrr file, well, which is missing...
Besides: the card is a NVidia Geforce MX420 and my display is a TFT
(1280x1024 pixel @ 24bit).
Bye,
Thilo.
