Subject: [Qemu-devel] [PATCH 0/2] Open disk images with O_DIRECT
Date: Wed, 28 Nov 2007 15:02:50 +0100 [thread overview]
Message-ID: <11962585701617@bull.net> (raw)
In-Reply-To:
These patches allow to open file using O_DIRECT and bypass the host I/O cache.
[PATCH 1/2] Add "directio" parameter to "-drive"
Using "directio=on" with "-drive" will open the disk image
file using "O_DIRECT".
[PATCH 2/2] Direct IDE I/O
This patch enhances the "-drive ,directio=on" mode with IDE drive emulation
by removing the buffer used in the IDE emulation.
Laurent
