Subject: Re: [Qemu-devel] [PATCH 2/2] virtio-blk: reject configs with logical block size > physical block size
Date: Wed, 06 Dec 2017 15:41:20 -0500 [thread overview]
Message-ID: <yq1wp1zzj0v.fsf@oracle.com> (raw)
In-Reply-To: <0a69463200d64d81dc27898ff92ecd10b126d968.1512589016.git.mark.kanda@oracle.com> (Mark Kanda's message of "Wed, 6 Dec 2017 13:54:01 -0600")
Mark,
> virtio-blk logical block size should never be larger than physical block
> size because it doesn't make sense to have such configurations. QEMU doesn't
> have a way to effectively express this condition; the best it can do is
> report the physical block exponent as 0 - indicating the logical block size
> equals the physical block size.

> This is identical to commit 3da023b5827543ee4c022986ea2ad9d1274410b2
> but applied to virtio-blk (instead of virtio-scsi).
