[Xen-ia64-devel] Re: [PATCH][RFC][IA64] Accelerate IDE PIO on HVM/IA64
Hi, Alan
Multimedia was out of my thought since my target is IA64.
What a gorgeous music player it is! :)
For handling inb/inw/inl, I already support inw/inl except inb.
inb is processed with the previous mechanism.
All I did is to move ide_data_(read|write)[wl] functions in Qemu
into the hypervisor.
Thanks,
Kouya
