Subject: Re: [PATCH kernel] x86/swiotlb/amd: Half the size if allocation failed
Date: Sun, 30 Oct 2022 09:05:40 +0100 [thread overview]
Message-ID: <20221030080540.GH4214@lst.de> (raw)

The subject looks wrong - this just touches the swiotlb code, and
nothing x86 or AMD specific.
The code flow now looks a little confusing. Can yu just add a little
swiotlb_memblock_alloc helper that does the two variants of memblock
allocation and remap, so that we can keep a simply
loop around them in the caller?
