Quentin Garnier elkészítette az NVidia driver (gyári, az NVidia által szállított zárt forrású, bináris driver) első betölthető kernel modul (loadable kernel module (LKM)) verzióját. Ez a kiadás teszt jellegű, egyelőre csak az elképzelés tesztelésére való. A teszteléshez NetBSD-current rendszerre van szükség, de a kód egészen jól visszafele-kompatibilis, néhány fenntartással. Például a használathoz 'options KVM86'-tal kell a kernelt konfigurálni. A működő hardverek között van a RIVA TNT2 Model 64 (PCI), GeForce2 MX/MX 400, Vanta(AGP), stb.Subject: NVidia drivers: preliminary LKM version

Hi all,
I've finally made a LKM version of the driver. There are a few requisites and my usual warnings about stability.
Note that there is no new feature nor bugfix (like console blanking, OpenGL-induced later kernel panic or Linux binaries compatibility). Report to archives and http://cubidou.nerim.net/ for a list of known issues.
This release is very rough and mostly meant to test the installation procedure. If you've never used the driver before, keep a backup of /usr/X11R6 neaby.
You will need a -current system, but the code itself should be quite backward compatible, with the following caveats:
o the AGP card will not be found by the code if there also is a PCI one in 1.6
o OpenGL code will immediately lead to a segfault in 1.6
o XFree86 4.2 and 4.3 need some patching, see http://cubidou.nerim.net for the details. Note that a 4.3 compiled from a very recent xsrc won't need any patch (see tech-x11 archives).
xdelta is needed to patch binaries (it is available in the devel category of pkgsrc).
You can download the code at (but please read the rest of this mail before doing anything with it):
http://cubidou.nerim.net/NVIDIA_NetBSD-1.0-3203-0.tgz
The tarball expands to several directories:
o mmr: it contains a LKM that emulates FreeBSD /dev/mem MTRR operations. The major number is dynamic and I don't provide a script to recreate the device node at load time, so beware of keeping a node in sync with the LKM.
o nvidia: it contains the LKM that links against NVidia's binary kernel module. The major numbers are hard-coded (180 and 181), and the device nodes may be created using the 'postinstall' target in the 'driver' directory.
Those two directories use bsd.kmod.mk, and should install the resulting LKMs in /usr/lkm.
o libNvGLcompat: it contains a small shared library that exports an empty and weak sched_yield so that applications that are not linked against libpthread can use libGL. It uses
bsd.lib.mk and installs stuff into /usr/lib.
o binaries: it contains binaries as shipped by NVidia. Some of them need to be patched to be used with NetBSD.
o patches: it contains xdelta patchfiles against NVidia binaries.
o driver: it contains a Makefile that patches and installs the relevant the XFree86 binary driver (nvidia_drv.o). The 'postinstall' target creates device nodes for up to two cards (my setup, I doubt that many people have more than two in a single computer...).
o glx: it contains a Makefile that patches and installs the relevant files to use OpenGL with the driver. Note that a simple 'make && make install' in the top directory will simply remove files that prevent the use of the driver. There's a 'backup' target that can be used though.
There is a Makefile at the root, so if you type 'make && make install', it should compile and install the LKMs and the XFree86 driver. By default, OpenGL stuff is not installed (the content of the Makefile is pretty straightforward).
To avoid any library issue, add the following lines to /etc/ld.so.conf:
libGL.so.1 machdep.fpu_present 1:libNvGLcompat.so.0,libGL.so.1
If you're willing to test XvMCNVIDIA (please let me know if you do, I can't do it myself since I don't own any GF4-based card), you may want to add a similar line for libXvMCNVIDIA.so.1.
I'm waiting for feedback of errors and incompatibilities with some components or versions. I plan on making a real release soon (I'd like to do that tomorrow) along with a pkgsrc version.
