2.6.9-rc2-mm4 and nvidia 1.0-6111

2.6.9-rc2-mm4 and nvidia 1.0-6111

[Sid Boyce]

The usual patches applied that made it work with -mm3.
Changed all instances of NV_REMAP_PAGE_RANGE to NV_REMAP_PFN_RANGE and 
nv_remap_page_range to nv_remap_pfn_range in nv.c, nv-linux.h,
os-agp.c and os-interface.c as redifined in 
/usr/src/linux-2.6.9-rc2-mm4/include/linux/mm.h.
The module builds and installs without problems, but on init 5, I get 
thrown back to vt1, /var/log/XFree86.0.log gives the error:-
(--) NVIDIA(0): Linear framebuffer at 0xD8000000
(--) NVIDIA(0): MMIO registers at 0xE1000000

This is a known issue and it's releated to some changes in Andrew's tree. Not 
to sound pesimistic but in the future expect the nvidia drivers to be broken 
for the -mm tree, it is after an the expiremental kernel tree.

I did revert these patches:

Isn't there an nvidia-linux mailing list?  This is really OT for LKML.

I had one for a while where I posted patches but it never gained much
momentum.  Unless there is a sizable group of people who want this I
don't see any need to resurrect it.

OK, makes sense.  With so many people using the driver I guess it's just
easiest to deal with nvidia problems on LKML.

Just about any out-of-kernel driver using Changed-API-X will be broken, free 
or non-free. Something more general like linux-drivers or 
linux-kernel-drivers would probably make more sense.

Sometimes changes in -mm even break in-kernel drivers; it's not really an 
"NVIDIA problem" as such. I agree with Lee though; it's an unwritten rule 
that you prefix a subject with [OT] when speaking about something which isn't 
directly relevant to the kernel.

(By the way, if this breaks outside of -mm patches will appear for stable 
kernels on http://minion.de/ as did with the 2.5 development tree.)

If there are more than a handful of people I'll restart linux-nvidia
(it was linux-nvidia@list.f00f.org, subscription via majordomo or
similar) since the noise on LKML will just piss people off.

Thanks, it did seem an easy thing to fix, when it built and inmod, I had 
high hopes.

So, in addition to the patches from 
http://00f.net/blogs/index.php/2004/09/07/nvidia_kernel_module_and_linux_2_6_9_mm 
  I've changed NV_REMAP_PAGE_RANGE to NV_REMAP_PFN_RANGE and 
remap_page_range to remap_pfn_range in nv-linux.h, nv.c, os-agp.c, and 
os-interface.c, the missing piece -- see below. I may get around to 
posting patches to the nvidia forum later today.

I'm not sure if I can divulge the name of my helper in case he gets 
showered by unwanted email, but a suggested additional change to 
nv-linux.h has fixed it.
#define NV_REMAP_PFN_RANGE(from, offset, x...) \
      remap_pfn_range(vma, from, ((offset)) >> PAGE_SHIFT), x)

Regards
Sid.
