Subject: Re: [Qemu-devel] [PATCH 8/8] s390: Add new channel I/O based virtio transport.
Date: Wed, 16 Jan 2013 08:46:02 -0800 [thread overview]
Message-ID: <50F6D94A.40600@twiddle.net> (raw)
In-Reply-To: <22014A51-6745-4B48-AF72-4AEEE5AB67E2@suse.de>
$SUBJECT reminds me that the tcg s390x port is now prepared
to implement channel insns, but previously there were no
channels worth talking about:
> /* I/O Instructions. For each we simply indicate non-operation. */
> C(0xb276, XSCH, S, Z, 0, 0, 0, 0, subchannel, 0)
> C(0xb230, CSCH, S, Z, 0, 0, 0, 0, subchannel, 0)
> C(0xb231, HSCH, S, Z, 0, 0, 0, 0, subchannel, 0)
> C(0xb232, MSCH, S, Z, 0, 0, 0, 0, subchannel, 0)
> C(0xb23b, RCHP, S, Z, 0, 0, 0, 0, subchannel, 0)
> C(0xb238, RSCH, S, Z, 0, 0, 0, 0, subchannel, 0)
> C(0xb233, SSCH, S, Z, 0, 0, 0, 0, subchannel, 0)
> C(0xb234, STSCH, S, Z, 0, 0, 0, 0, subchannel, 0)
> C(0xb235, TSCH, S, Z, 0, 0, 0, 0, subchannel, 0)
With a bit of help, I can make these emulated insns implement
virtio as well.
