Subject: Re: [PATCH v4 00/10] arm64: ptdump: View the second stage page-tables
Date: Thu, 21 Dec 2023 18:36:28 +0000	[thread overview]
Message-ID: <ZYSFrFDHKo_ZTkxM@linux.dev> (raw)

Hi Sebastian,

I'm going to try and review the series a bit more after the holidays,
but in general this is unecessarily complex. Furthermore, building out
the feature for pKVM *first* rather than 'normal' VMs makes it all very
challenging to follow.

I would strongly prefer that this series be split in two, adding support
for 'normal' VMs with a follow-up series for getting the pKVM plumbing
in place for host stage-2.

Thanks,
Oliver
