Hi, Here is the v3 patch set of amdkfd. This version contains changes and fixes to code, as agreed on during the review of the v2 patch set. The major changes are: - There are two new module parameters: # of processes and # of queues per process. The defaults, as agreed on in the v2 review, are 32 and 128 respectively. This sets the default amount of GART address space that amdkfd requires to 3.5MB (3MB for userspace queues mqds and 0.5MB for other stuff, such as mqd for kernel queue, hpd for pipelines, etc.) - All the GART address space usage of amdkfd is done inside a single contiguous buffer that is allocated from system memory, and pinned to the start of the GART during the startup of amdkfd (which is just after the startup of radeon). The management of this buffer is done by the radeon sa manager. This buffer is not evict-able. - Mapping of doorbells is initiated by the userspace lib (by mmap syscall), instead of initiating it from inside an ioctl (using vm_mmap). - Removed ioctls for exclusive access to performance counters - Added documentation about the QCM (Queue Control Management), apertures and interfaces between amdkfd and radeon. Two important notes: - The topology patch has not been changed. Look at http://lists.freedesktop.org/archives/dri-devel/2014-July/065042.html for my response. I also put my answer as an explanation in the commit msg of the patch. - There are still some minor code style issues I need to fix. I didn't want to delay v3 any further but I will publish either v4 with those fixes, or just relevant patches if the whole patch set will be merged. For people who like to review using git, the v3 patch set is located at: http://cgit.freedesktop.org/~gabbayo/linux/log/?h=kfd-next-3.17-v3 In addition, I would like to announce that we have uploaded the userspace lib that accompanies amdkfd. That lib is called "libhsakmt" and you can view it at: http://cgit.freedesktop.org/~gabbayo/libhsakmt Alexey Skidanov (1): amdkfd: Implement the Get Process Aperture IOCTL Andrew Lewycky (3): amdkfd:
