Hello thomas001,

Thank you so much on your work porting cedarview-drm. I have had a great experience running this drm driver on Linux kernels 3.7, 3.8, and 3.9.

However, with the release of 3.10, I'm now getting errors compiling this drm as follows:

It seems that the file include/linux/proc_fs.h have been significantly changed with the Linux-3.10 release, where the type names read_proc_t and write_proc_t used to be defined in previous releases 3.7 to 3.9.

Can something be done to make this drm driver compatible with the 3.10 release?

If you were wondering about the versioning, I made a few local version changes in cedarview-drm-1.0.3 where -37 denotes the Linux kernel release where it was tested upon by you, i.e. Linux 3.7, from the master branch.

I manged to compile this under ARCH 3.11 kernel. But can't get hardware accelerated playback to work. Anybody able to do so?

I'm running on an Intel DN2800MT board using an LVDS display. Kernel 3.11.0-17-generic from the lts-saucy package, Ubuntu 12.04.4.

Any tips on getting the linux-3.11 branch working? I compile and install the module successfully with DKMS per your instructions, but after booting I can't get X to run successfully. sudo lspci -v -s 00:02.0 reports:

Looks like X is trying to use the vesa driver:

Without your cedarview-drm driver, gma500 runs by default, and X runs fine, except that the LVDS display shows nothing past the Intel boot logo and a purple flash or two. Oddly, I can run VNC and see the screen that should be on my LVDS display, but nothing shows up on the display. Without cedarview-drm sudo lspci -v -s 00:02.0 reports:

Also, I did have this running previously with the 3.2 kernel and the older cedarview driver from wherever I found it on the Internets. So it can work...
