Because the question which leaps to mind is: shouldn't the
"applications that use shmem" be changed to "configure mTHP through
sysfs" *before* "using shmem"? Seems pretty basic.
Sorry about that, I'll try to improve the commit messages and add more
details.
As mentioned in the example I gave ("DRM GEM objects"), my main use is
GEM objects backed by shmem. I'd like to use Huge Pages on the GPU and I
can only do that if I have contiguous memory to back my objects.
I can't think how I can change sysfs from a DRM driver.
So your term "applications" actually refers to in-kernel drivers?
Yes, I'll make it clearer in v4. Sorry for the vague commit message.
Best Regards,
