Re: [vfio-users] Fedora 23 ACS Patch



Thanks for replying.

To stress, I am new to this process.  I have ran Linux as my primary desktop for about 2 years.

How would I get a copy of an ACS patch for my kernel? Or failing that, what should I do to create one?  I am not a C programmer, so would be limited in my ability to write one.

He likely refers to a method to build a rpm directly and solely trough
the kernel's makefile. 'make rpm-pkg' is possible since as far as I can
remember, along with 'make deb-pkg'

'patch' has an '-i' argument to take a file as input - not that cat'ing
is wrong, both methods work.
You should look at what exact errors you get to have proper help, errors
in patching usually means you are using incompatible versions of the
patch and the kernel together, where the code has changed enough to
confuse patch. As it has been told, look for a patch that's appropriate
to your kernel version. Errors during the building of the kernel need
more detail to be understood
