Just a few questions:

1. • What are "PX" and "non-PX" cards?

PX = PowerXpress. PX systems are laptops with two GPUs, an integrated and a discrete GPU.

2. • Aren't these going to disable power management in my GPU? What's the

difference between applying those and using "radeon.runpm=0" in grub?

It does not disable power management. It only disables the special handling for PX systems which gets incorrectly applied to non-PX systems in certain cases. When you apply the patches you shouldn't need to add the radeon.runpm=0 option. If radeon.runpm=0 fixes the issue, so should the patches.

3. • How can I apply those?

If you are using git: git am <patch file>

Otherwise: patch -p1 -i <patch file>
