how to compile master LE with Nvidia legacy driver 304.134 ?

Goga777 · January 4, 2017 at 9:58 PM

My external PCI Geforce GT610 card can't work with 340 legacy driver and with current nvidia drivers. I would like to try to use legacy 304.134 drivers

According our discussion here is LibreELEC Testbuilds for x86_64 (Kodi 18.0) I will remove the patch
LibreELEC.tv/xf86-video-nvidia-legacy-kernel-4.9.patch at master · LibreELEC/LibreELEC.tv · GitHub

and will modify in LibreELEC.tv/package.mk at master · LibreELEC/LibreELEC.tv · GitHub the line
PKG_VERSION="340.101

should I do anything else for successful LE compilation ?

that sounds about right

I could compile, but I couldn't start X with 304.134 legacy nvidia drivers - in Xorg log there is message that it is not possible to load nvidia.ko - see kernel log. But I couldn't find nothing about kernel log. Seems, for current kernel in LE branch need to have some patch for 304 legacy driver

so, here is dmesg output Ubuntu Pastebin
I think the problem is with that lines

Code

Xorg log here is Ubuntu Pastebin

seems, need to patch the kernel 4.9 for missing symbol mtrr_del

aVLB <= this is the patch carried by most distro's

thank you
what should I do with it ? To put in /packages/x11/driver/xf86-video-nvidia-legacy/patches and recompile again LE ? or to patch manually with patch -p1 < disable_mttr.patch the file nv-linux.h in ~/http://LibreELEC.tv/build.LibreELEC-Generic.x86_64-8.0-devel/xf86-video-nvidia-legacy-304.134/kernel

Put it in the patches subdirectory and re-run the build command. It will clean/patch/rebuild only that package.

I could compile , but new error arisen during nvidia module loading

Looks like 304.134 requires the equivalent of the 4.9 patch you removed in your first post.

You can try this patch: bOZU, which is from Ubuntu: 304.132-0ubuntu3 : nvidia-graphics-drivers-304 package : Ubuntu

Copy it into the xf86-video-nvidia-legacy/patches directory.

Goga777 · January 8, 2017 at 9:34 PM

in bOZU there are 3 patches, but I removed only one - /http://LibreELEC.tv/blob/master/packages/x11/driver/xf86-video-nvidia-legacy/patches/xf86-video-nvidia-legacy-kernel-4.9.patch

Should I apply all 3 patches ?

**milhouse** · January 8, 2017 at 10:16 PM

bOZU is a single patch that contains three *hunks*.

You certainly need the first hunk. I don't know if you need the second and third hunks, Ubuntu seem to think so (and this patch does apply on top of 304.134 despite being originally based on 304.132).

If it doesn't build with all three hunks then drop the second and third hunks (delete from the second "diff" onwards).

Goga777 · January 14, 2017 at 4:14 PM

yes, only with the first hunk I could compile and run LE. Thank you again, the issue was solved
