Re: [Xen-devel] Compiling nouveau open source nvidia graphics card drivers for Xen paravirt-operations domain 0 kernel
Dear Pasi,
I have nouveau driver on my stock/default Fedora 11 kernel that does not
depend on ttm.
lsmod | grep ttm shows up nothing.

Dear Xen developers,
Just now in my earlier email, I renamed drivers/gpu/drm/ttm to
drivers/gpu/drm/ttm_orig.
However, I forgot to rename include/drm/ttm to include/drm/ttm_orig. Hence
the build process complains Makefile in ttm is not found.
Now, I have renamed include/drm/ttm to include/drm/ttm_orig. I have
successfully excluded TTM from being built.
Uhm.. it looks like that nouveau driver _requires_ TTM.

But now I get compile errors with nouveau drivers.

From the error messages above, it appears that nouveau drivers depended on
TTM GPU video memory management driver code. Hence, I cannot exclude TTM
from being compiled.
But I get TTM build errors. And hence my nouveau drivers cannot be
compiled, since it depended on TTM for graphics processor video memory
management.
How can I resolve this? Is it possible that nouveau display drivers are not
compatible with Xen paravirt-ops dom 0 kernels just like official NVIDIA
display drivers?
If this is the case, I would have to change my graphics card to one which
is supported under pv_ops kernel. I had chosen NVIDIA on first instinct
because it historically supports Linux.
I would like to keep my NVIDIA card, so are there any patches for ttm code?
Thank you.

Dear Xen developers,
I am using Xen paravirt-operations domain 0 kernels 2.6.30-rc3 and
2.6.31-rc6 cloned from Jeremy Fitzhardinge's kernel git tree.
I am trying to compile the nouveau open source drivers for NVIDIA
graphics cards.
I am following the nouveau kernel module build instructions at
http://nouveau.freedesktop.org/wiki/InstallDRM
Specifically, I am following Section
3.2. Alt: Rebuilding your existing kernel with new DRM and
Nouveau parts
in the nouveau kernel module build instructions.
However, when I am compiling the kernel and kernel modules (using
make), it encountered an error with the translation-table map (TTM)
GPU video memory management driver.

I would like to exclude TTM from being compiled. May I know which
build scripts do I modify?
I tried renaming drivers/gpu/ttm to drivers/gpu/ttm_orig in the kernel
souces but it doesn't work.
scripts/Makefile.build:44:
/usr/src/kernels/2.6.31-rc6-enming.teo/drivers/gpu/drm/ttm/Makefile:
No such file or directory
make[4]: *** No rule to make target
`/usr/src/kernels/2.6.31-rc6-enming.teo/drivers/gpu/drm/ttm/Makefile'.
Stop.
make[3]: *** [drivers/gpu/drm/ttm] Error 2
make[2]: *** [drivers/gpu/drm] Error 2
make[1]: *** [drivers/gpu] Error 2
make: *** [drivers] Error 2
It simply complains that ttm directory cannot be found and Makefile in
ttm dir does not exist. This is of course due to me renaming the ttm
directory in the kernel sources. I want to prevent ttm from being built.
Thank you very much.
