Bug#533450: maintaining poulsbo in Debian



Hi,

I had some sort of success building and running psb on 2.6.31 and
2.6.32.

There are a few caveats:

1. I have to run the kernel with mem=1500MB (I read that 500MB and
   1000MB are working too) otherwise X won't load. I also load psb with
   ignore_acpi=1

2. I had to override libdrm2's shared objects with psb's provided one:
   -rw-r--r-- 1 root root 37806 Dec  6 21:45 /usr/lib/libdrm_poulsbo.a
   lrwxrwxrwx 1 root root    23 Dec  6 21:47 /usr/lib/libdrm_poulsbo.so -> libdrm_poulsbo.so.2.3.0
   lrwxrwxrwx 1 root root    23 Dec  6 21:47 /usr/lib/libdrm_poulsbo.so.2 -> libdrm_poulsbo.so.2.3.0
   -rw-r--r-- 1 root root 35852 Dec  6 21:45 /usr/lib/libdrm_poulsbo.so.2.3.0
   lrwxrwxrwx 1 root root    23 Dec  7 21:40 /usr/lib/libdrm.so.2 -> libdrm_poulsbo.so.2.3.0

3. I had to add loading of the kernel module to rc.local (rather than
   /etc/modules) and move the startup links of gdm after that (S24
   suffices).

Overall, the status is quite sad: forget about s2ram, the X driver won't
probably work on xorg 1.7 and the machine in general is not very stable.

I have packages[1] built against squeeze and kernel 2.6.31 here[2] you
should be able to rebuild them after installing the dependencies or you
can just install the deb files[3].

Something I'm really annoyed about is that I couldn't find source files
other than the ones from ubuntu or fedora.

Notes:
[1]: the quality of the packages is pretty low, not even close to
anything that can be considered for upload. I took the ubuntu packages
and re-worked them a bit (to use quilt, additional patches, moved libdrm
to libdrm_poulsbo, etc.). Anyway, good enough for now and it's probably
not the case to have any of these packages in Debian.

[3]: note that you will have either to tweak the libdrm_poulsbo package
to divert the libdrm.so.2 link or create the link yourself. I may add it
at some point._poulsbo, etc.). Anyway, good enough for now and it's
probably not the case to have any of these packages in Debian.
