Subject: [PATCH v2 0/3] ARM ZSTD boot compression
Date: Fri, 28 Aug 2026 22:32:18 +0200	[thread overview]
Message-ID: <20260828-zstd2-v2-0-4d9ce7150877@kemnade.info> (raw)

Add ZSTD compression to still have a quite high compression but with
not too much boot delay penality. 

Signed-off-by: Andreas Kemnade <andreas@kemnade.info>

Changes in v2:
- rebased
- practically rewritten 3/3 (and therefore changed author)
- added more measurements
- Link to v1: https://lore.kernel.org/lkml/ZDoDYh01GYjdwp63@probook/
