[PATCH v3 08/23] amdkfd: Add amdkfd skeleton driver
Oded Gabbay
oded.gabbay at amd.com
Tue Aug 5 08:30:36 PDT 2014
This patch adds the amdkfd skeleton driver. The driver does nothing except
define a /dev/kfd device.
It returns -ENODEV on all amdkfd IOCTLs.
(v3) move bool to end of struct
(v3) remove pmc ioctls
(v3) add meaningful error message for ioctl error
