2016-02-27drm/amdkfd: Track when module's init is completeOded Gabbay1-1/+1
Current dependencies between amdkfd and radeon/amdgpu force the loading of amdkfd _before_ radeon and/or amdgpu are loaded. When all these kernel drivers are built as modules, this ordering is enforced by the kernel built-in mechanism of loading dependent modules. However, there is no such mechanism in case where all these drivers are compiled inside the kernel image (not as modules). The current way to enforce loading of amdkfd before radeon/amdgpu, is to put amdkfd before radeon/amdgpu in the drm Makefile, but that method is way too fragile. In addition, there is no kernel mechanism to check whether a kernel driver that is built inside the kernel image, has already been loaded. To solve this, this patch adds to kfd_module.c a new static variable, amdkfd_init_completed, that is set to 1 only when amdkfd's module initialization function has been completed (successfully). kgd2kfd_init(), which is the initialization function of the kgd-->kfd interface, and which is the first function in amdkfd called by radeon/amdgpu, will return successfully only if amdkfd_init_completed is equal 1. If amdkfd_init_completed is not equal to 1, kgd2kfd_init() will return -EPROBE_DEFER to signal radeon/amdgpu they need to defer their loading until amdkfd is loaded.

2014-07-15drm/radeon: Add radeon <--> amdkfd interfaceOded Gabbay1-0/+185
This patch adds the interface between the radeon driver and the amdkfd driver. The interface implementation is contained in radeon_kfd.c and radeon_kfd.h. The interface itself is represented by a pointer to struct kfd_dev. The pointer is located inside radeon_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 avoiding locking between amdkfd and radeon. 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 radeon. v3: Add interface for sa manager init and fini. The init function will allocate a buffer on system memory and pin it to the GART address space via the radeon sa manager. All mappings of buffers to GART address space are done via the radeon sa manager. The interface of allocate memory will use the radeon sa manager to sub allocate from the single buffer that was allocated during the init function. Change lower_32/upper_32 calls to use linux macros Add documentation for the interface v4: Change ptr field type in kgd_mem from uint32_t* to void* to match to type that is returned by radeon_sa_bo_cpu_addr v5: Change format of mqd structure to work with latest KV firmware Add support for AQL queues creation to enable working with open-source HSA runtime.
