Documentation: update config name in real-time architecture support2025-12-22T22:33:40ZLukas Bulwahnlukas.bulwahn@redhat.com2025-11-27T15:43:42Zurn:sha1:6c95f2d67f7da7175b9bbb3e92284412aa074a98
Commit 4843a45ef9fe8 ("entry: Rename "kvm" entry code assets to "virt"
to genericize APIs") renames the config KVM_XFER_TO_GUEST_WORK to
VIRT_XFER_TO_GUEST_WORK.
Adjust the documentation to the current situation, and specifically
refer to the new name of the config.

Documentation: Add some hardware hints for real-time2025-12-22T22:33:40ZSebastian Andrzej Siewiorbigeasy@linutronix.de2025-11-27T15:43:41Zurn:sha1:7548c69f5167a00d7bbd43be9b6521351f9bedc6
Some thoughts on hardware that is used for real-time workload. Certainly
not complete but should cover some of the import topics such as:
- Main memory, caches and the possiblie control given by the hardware.
- What could happen by putting critical hardware behind USB or VirtIO.
- Allowing real-time tasks to consume the CPU entirely without giving
the system some time to breath.
- Networking with what the kernel provides.

The documents explain the design concepts behind PREEMPT_RT and highlight key
differences necessary to achieve it.
It also include a list of requirements that must be fulfilled to support
PREEMPT_RT on a given architecture.
