Hi,
I'm in a gap in my understanding need some help..
I'm porting a driver from bare metal to Dom0, xen 4.3, debian jessie kernel
3.14
I do a kmalloc and get a null returned dma_map_single().
Is there something I'm not setting correctly in dom0 kernel line ?
Does the dma_map_single() call work in dom0 ?
cheers
