Subject: [PATCH 0 of 5] dma api v3
Date: Fri, 12 Dec 2008 19:16:42 +0100 [thread overview]
Message-ID: <patchbomb.1229105802@duo.random> (raw)
Here the lastest patchset of the dma api against qemu svn. It should build and
you've only to set the DEBUG_BOUNCE somehow when preadv/pwritev aren't
available at compile time. Then you know iovcnt will always be 1 and it'll
handle up to size_t amount of dma in flight with 1M buffer (default setting
but can be reduced to 512bytes as long as max alignment required by any
hardware driver is 512bytes).
