Hello

I have a compilation error for drm-intel linux from today (12-Nov-2016) referring to undeclared variable - see output below:

"drm-intel linux from today (12-Nov-2016)" does not accurately specify what you're actually trying to build. We need the *upstream* git repo, branch, commit that fails.

We also need the kernel config you're trying to build.

I've seen a patch adding this, but this has not been merged upstream. We do not have this line in upstream source.

Here is the info:

repo: git://anongit.freedesktop.org/drm-intel
branch : drm-intel-nightly
commit: 1af808dba57ca773d463026a2e8a9296cb0db42a
kernel x86_64-4.9.0-rc4

kernel config file should be in next post
Comment 4 Jani Nikula 2016-11-15 15:33:12 UTC 
Again, current drm-intel-nightly does not have this.

I'm using drm-intel-nightly only, updated today, the last commit is 
7d920f01ab1c5b838011d553f5ac8f656061cacc

and the compilation error is still there
Comment 6 Chris Wilson 2016-11-16 07:30:14 UTC 
fatal: bad object 7d920f01ab1c5b838011d553f5ac8f656061cacc

$ git grep intel_crtc_set_crc_source
=1

Whatever you think you are compiling it is not drm-intel.
