Ok, folks,
I've identified what my problem is, trying to install the NVidia proprietary drivers: in kernel-devel-3.10.0-514.26.2.el7.x86_64,
there
is a file /usr/src/kernels/3.10.0-514.26.2.el7.x86_64/include/linux/fence.h
It does not exist in the kernel-devel-3.10.0-693.2.2.el7.x86_64 package. Is this something that got missed, or did HR drop it,
or....?
I'm running that kernel with Nvidia 384.90, but I get the nvidia driver from elrepo. where do you get yours?
Proprietary NVidia. Still, why is fence.h suddenly not there?
While I'm running the Plus kernel, it has the same files. What I'm seeing here is that fence.h has been renamed in the 693 kernel to dma-fence.h:
# locate fence.h
/usr/src/kernels/3.10.0-514.26.2.el7.centos.plus.x86_64/include/linux/fence.h /usr/src/kernels/3.10.0-514.26.2.el7.centos.plus.x86_64/include/linux/seqno-fence.h /usr/src/kernels/3.10.0-514.26.2.el7.centos.plus.x86_64/include/trace/events/fence.h /usr/src/kernels/3.10.0-693.2.2.el7.centos.plus.x86_64/include/linux/dma-fence.h /usr/src/kernels/3.10.0-693.2.2.el7.centos.plus.x86_64/include/linux/seqno-fence.h /usr/src/kernels/3.10.0-693.2.2.el7.centos.plus.x86_64/include/trace/events/dma_fence.h
Looks like upstream renamed it for some reason.
Not good - I did a diff of fence.h and dma_fence.h, it *appears* to be the same structures, but all with different names. That's not going to compile.
Sorry, but I really don't believe it is good, much less best practice to do something like removing a kernel include file within one release. If they'd made it go a away for 7.0, I would deal, but to suddenly drop it, bad.
