Kernel 2.6.28 support?

[cthulhu]

Since I've got a fairly recent laptop (Asus U6V), I've been testing the lastest kernels to get everything working (HDMI audio especially).

Today I've built and booted a 2.6.28-rc1 kernel with success. Unfortunately I couldn't install the nVidia X.org driver since compilation of the kernel module fails. The kernel team has moved architecture specific headers from include/asm-x86 to arch/x86/include/asm, and thus compilation of conftest (and the actual kernel module itself) fails.

Do you have a patch to enable 2.6.28 support or is there a new beta with 2.6.28 support in the works? In case of the latter, can you perhaps reveal an ETA?

Thanks in advance

This happens every kernel release, give it a few days and someone will probably post a hacked up patch to get 177.80 working with it.

I will probably have a poke it myself before the weekend is out.

Atm i'm using 2.6.28-rc1+(git patch for NCQ bug) and the free nv driver.

Look in your include/asm and you know, why the driver not work.
Make a symlink from arch/x86/include/asm to include /asm-x86 and the driver will build.

I created the symlink you suggested. At least, the build starts but it ends with the following error:

So, as with every kernel release, a patch seems necessary to compile the nvidia driver with 2.6.28. I have put a full build log in attachment.

Thanks for your help.

Here is the /var/log/nvidia-installer.log from the test, i have made:

[FrancoisVal]

It seems you are running an x86 machine. I try to compile it on a 64 bit system and it fails.

[towo|]

For 64bit i have no clue, only tryed for 32 bit.

[agent5]

After linking the asm dir, as suggested here, the building process starts but fails on my x86 machine here

complete installer logfile

any further ideas or do we just have to wait ?

[siddly]

Doesn't start to build here either. Hoping the symlink here is correct, x86_64 target.

so the driver build without problem.

Patched, working and lightly tested here:

1. Copy include/asm-x86/asm-offsets.h to /arch/x86/include/asm. This was the only file in my asm-x86 folder and I didn't want to change the symlink and cut anything off from it.
2. Symlink include/asm to ../arch/x86/include/asm
3. Apply this patch to fix ACPI on x86_64, it is probably needed on x86 too.

Edit: Patch mirror here

Thanks, works fine ... have to go back to 2.6.27-git10 as thunderbird crashes on 2.6.28-rc1-git1, nothing to do with the driver however.
