Subject: [PATCH PREVIEW RFC 0/6] Add support for boot-time caching
Date: Tue, 23 Sep 2025 15:23:37 +0100 [thread overview]
Message-ID: <20250923-bootcache-v1-0-4f86fdc38b4e@thegoodpenguin.co.uk> (raw)
This patch series provides a simple key-value cache for storing boot-time
configuration data. The goal is to allow kernel components and drivers to
cache time-consuming-to-compute values during boot, enabling faster
subsequent boots by avoiding redundant initialization work.
During kernel boot, many subsystems perform expensive operations like:
- Hardware detection and configuration
- Performance tuning calculations
- Resource allocation decisions
- Driver initialization parameters
These operations often produce the same results across boots on the same
hardware, making them good candidates for caching.
