Subject: [PATCH v5 11/11] Documentation: PCI: Add documentation for Live Update
Date: Tue, 12 May 2026 18:48:46 +0000	[thread overview]
Message-ID: <20260512184846.119396-12-dmatlack@google.com> (raw)
In-Reply-To: <20260512184846.119396-1-dmatlack@google.com>

Add documentation files for the PCI subsystem's participation in Live
Update.

These documentation files are generated from the kernel-doc comments
in the PCI Live Update source code. They describe the File-Lifecycle
Bound (FLB) API, the device tracking API, and the specific policies
applied to preserved devices (such as bus number inheritance and bus
mastering preservation).
