Greetings,
My Name is Daniel Castro, I am working with the Xen Hypervisor
Community in order to change our existing BIOS for SeaBIOS. For now we
are interested to modify the int 13 where the higher level disk driver
abstraction resides, We will plug into it in order to communicate via
shared memory and replace the existing emulated devices that are being
used (Xen only). The result will be a patch for your source code
maintainer that will include support for Xen.
I am going to write new code to allow SeaBios to use the split-driver
model of Xen to write directly to the back-end device of Xen using
shared memory, but was wondering if I could leverage the drive
abstraction layer that SeaBIOS has for hard drives?
How and where does Virtio handle this?
And also where is the best place to insert the code?
So in a very near future I could send patch to the SeaBIOS repository.
I will greatly appreciate any help and information you can give us
that will help us to join efforts and include SeaBIOS into Xen. If you
have any suggestions on the best way to do this please do not hesitate
to email me, I am not familiar with SeaBIOS so please be as detailed
as posible.
Thank you all for your time,
Best Regards,
Daniel
