Subject: Re: [PATCH net-next v2 3/4] virtio-net: auto-tune mergeable rx buffer size for improved performance
Date: Wed, 8 Jan 2014 19:41:58 -0800 [thread overview]
Message-ID: <CANJ5vPLvDff5PMYNGvtt-dd=md8b46ZXAYLv-KnerNcfzDNHpw@mail.gmail.com> (raw)
In-Reply-To: <CANJ5vP+_aK0PMc6-hwbu6PduVNDe8jbWR19cN5C+k4mWQzdTGg@mail.gmail.com>
Sorry, forgot to mention - if we want to explore combining the buffer
address and truesize into a single void *, we could also exploit the
fact that our size ranges from aligned GOOD_PACKET_LEN to PAGE_SIZE, and
potentially encode fewer values for truesize (and require a smaller
alignment than 256). The prior e-mails discussion of 256 byte alignment
with 256 values is just one potential design point.
Best,
Mike
