8 years ago Could you link to the git tree you are using and paste in the git commit hash? Sometimes I need to tweak the patch for a specific kernel version. Did you compile the whole kernel or download it from a package repo? I may be able to come up with better instructions on how to build. My knowledge of kernel patch development has improved a bit since I wrote that.

8 years ago Hi @teknotus This is where I got the patch from: https://github.com/teknotus/depthview/tree/kernelpatchfmt
Latest commit is on March 3rd, 2015. As for the hash I get the following for this branch:
ecd476ca4c7539c15d4332b99362bf0ae38cd9a6
Appreciate your help as I am currently not getting IR stream from my camera

8 years ago I meant where did you get the kernel source. lts-vivid is a different kernel tree than the Linus Torvalds tree I linked to.

8 years ago @teknotus apt-get source linux-image-$(uname -r) gets me lts-vivid. uname-r returns: 3.19.0-30-generic

8 years ago @teknotus, gives me the same error when I patch the kernel source I got from Linus Trovald's tree.

8 years ago Here is an update from patching Linus Trovald's tree:

8 years ago This time it is complaining about "media/videobuf2-v4l2.h"

8 years ago I'm thinking the patch is probably OK, but I need to fix my instructions.

8 years ago For the out of kernel tree module I'm working on at the moment the makefile looks like this.
KDIR ?= /lib/modules/uname -r/build
default: $(MAKE) -C $(KDIR) M=$$PWD
So rather than the -C going to a headers directory it seems it should be going to a build directory.

8 years ago Also librealsense has a patch that supports most of the F200 formats, and a script to patch the kernel. You could try that.

Hi, I get the following error after applying patch and trying to make:
