Re graphics Kernel patch, how does this 'use it now' fix relate to Puppy, if at all?

Have you (or anyone else) applied this? Does it work?

Could it be made into a pet file, with a 'pinstall.sh' file, that automatically installs this 'patch'?

I don't know enough to say whether or not this 'fix' will improve performance in Puppy, but I could make it into a pet, I guess...

Unless someone wants to beat me to it Wink

I guess we are both asking the same question, and nobody with real knowledge is answering Sad

I got as far as the "mount" command. I think mount needs to be updated.

This patch isn't going to help your performance anyway unless you commonly kick off resource hogging jobs in the terminal. All desktop apps would be in the same cgroup.

May be useful to packagers ... allowing online video etc.. while compiling.
or while batch processing audio/video/etc...
and other resource intensive CLI tasks.

Subject description: Patch that really improves performance
 

Can someone apply the 200 line cgroup patch as well as the hugepage patch to a kernel that we all can use in PuppyLinux?

Look at the results of hugepage patch here: http://www.phoronix.com/scan.php?page=article&item=linux_transparent_hugepages&num=1

Thanks in advance,
Jonathan
