Hello All,
I am connecting my front and back for a block device.
I have collected from xenstore sectors, sector-size. But I also need:
u16 heads; // # heads
u16 cylinders; // # cylinders
u16 spt; // # sectors / track
I guess from the SeaBIOS perspective they are required, but from the
xen perspective how can I get them? pure math/translation?
Thanks,
Daniel

You can basically just make them up to fit the underlying device size, take a look at blkif_getgeo in Linux for example.
