[Qemu-devel] [PATCH 0/2] Open disk images with O_DIRECT

[Laurent Vivier]

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.
