drm/amdgpu: Fix KFD initialization for multi-GPU systems

2017-08-15T18:46:02Z

kfd2kgd is device-specific, so it should not be a global variable. Merge amdgpu_amdkfd_load_interface and amdgpu_amdkfd_device_probe so that it's only needed as a local variable in one function. Signed-off-by: Felix Kuehling Reviewed-by: Oded Gabbay Signed-off-by: Alex Deucher

drm/amdgpu: Return -EPROBE_DEFER when amdkfd not loaded

2016-02-27T20:52:40Z

amdgpu must load only after amdkfd's loading has been completed. If that is not enforced, then amdgpu's call into amdkfd's functions will cause a kernel BUG. When amdgpu and amdkfd are built as kernel modules, that rule is enforced by the kernel's modules loading mechanism. When amdgpu and amdkfd are built inside the kernel image, that rule is enforced by ordering in the drm Makefile (amdkfd before amdgpu). Instead of using drm Makefile ordering, we can now use deferred loading as amdkfd now returns -EPROBE_DEFER in kgd2kfd_init() when it is not yet loaded. This patch defers amdgpu loading by propagating -EPROBE_DEFER to the kernel's drivers loading infrastructure. That will put amdgpu into the pending drivers list (see description in dd.c). Once amdkfd is loaded, a call to kgd2kfd_init() will return successfully and amdgpu will be able to load. Signed-off-by: Oded Gabbay Reviewed-by: Alex Deucher

drm/amdgpu: Add amdgpu <--> amdkfd gfx8 interface

2015-07-20T06:16:48Z

This patch adds the gfx8 interface file between amdgpu and amdkfd. This interface file is currently in use when running on a Carrizo-based system. The interface itself is represented by a pointer to struct kfd_dev. The pointer is located inside amdgpu_device structure. All the register accesses that amdkfd need are done using this interface. This allows us to avoid direct register accesses in amdkfd proper, while also allows us to avoid locking between amdkfd and amdgpu. The single exception is the doorbells that are used in both of the drivers. However, because they are located in separate pci bar pages, the danger of sharing registers between the drivers is minimal. Having said that, we are planning to move the doorbells as well to amdgpu.
