Subject: [PATCH 0/2] powerpc/boot: Build wrapper with optimisations
Date: Wed, 10 Oct 2018 13:15:21 +1030 [thread overview]
Message-ID: <20181010024523.4921-1-joel@jms.id.au> (raw)
We currently build the wrapper with Os. This builds it with O2 instead,
reducing boot time when decompressing a compressed kernel. See patch
2 for details.
I've given this a spin with CONFIG_KERNEL_XZ on P9 and P8 as the
petitboot kernel.
