2018-05-18drm/amdgpu: conditionally compile amdgpu's amdkfd filesOded Gabbay1-6/+6
In case CONFIG_HSA_AMD is not chosen, there is no need to compile amdkfd files that reside inside amdgpu dirver. In addition, because amdkfd depends on x86_64 architecture and amdgpu is not, compiling amdkfd files under i386 architecture can cause compiler errors and warnings. This patch modifies amdgpu's makefile to build amdkfd files only if CONFIG_HSA_AMD is chosen. The only file to be compiled unconditionally is amdgpu_amdkfd.c There are stub functions that are compiled only if amdkfd is not compiled. In that case, calls from amdgpu driver proper will go to those functions instead of the real functions. v2: instead of using function pointers, use stub functions v3: initialize kgd2kfd to NULL in case amdkfd is not compiled Reviewed-by: Felix Kuehling <Felix.Kuehling@amd.com> Signed-off-by: Oded Gabbay <oded.gabbay@gmail.com>

2016-02-27drm/amdgpu: Return -EPROBE_DEFER when amdkfd not loadedOded Gabbay1-1/+1
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.

2015-07-20drm/amdgpu: Add amdgpu <--> amdkfd gfx8 interfaceBen Goz1-0/+1
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.

2015-07-20drm/amdgpu: Add H/W agnostic amdgpu <--> amdkfd interfaceOded Gabbay1-0/+64
This patch adds an interface file between amdgpu and amdkfd. This interface file is H/W agnostic, thus containing functions that operate the same for any AMD APU/GPU H/W generation. The functions in this interface mirror (some) of the functions in radeon_kfd.c (the radeon<-->amdkfd interface file). The main functions are: - amdgpu_amdkfd_init - initialize the amdkfd module - amdgpu_amdkfd_load_interface - load the H/W interface according to the currently probed device - amdgpu_amdkfd_device_probe - probe the device in amdkfd - amdgpu_amdkfd_device_init - initialize the device in amdkfd - amdgpu_amdkfd_interrupt - call the ISR of amdkfd - amdgpu_amdkfd_suspend - suspend callback from amdgpu - amdgpu_amdkfd_resume - resume callback from amdgpu This patch also modifies the relevant amdgpu files, to use this new interface.
