drm/amdkfd: drop struct kfd_cu_info I think this was an abstraction back from when kfd supported both radeon and amdgpu. Since we just support amdgpu now, there is no more need for this and we can use the amdgpu structures directly. This also avoids having the kfd_cu_info structures on the stack when inlining which can blow up the stack.

drm/amdkfd: Change the control stack MTYPE from UC to NC on GFX9 CWSR fails on Raven if the control stack is MTYPE_UC, which is used for regular GART mappings. As a workaround we map it using MTYPE_NC. The MEC firmware expects the control stack at one page offset from the start of the MQD so it is part of the MQD allocation on GFXv9. AMDGPU added a memory allocation flag just for this purpose.

drm/amdkfd: Track when module's init is complete 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.

drm/radeon: Initialize compute vmid This patch moves to radeon the initialization of compute vmid. That initializations was done in kfd-->kgd interface, but doing it in radeon as part of radeon's H/W initialization routines is more appropriate. In addition, this simplifies the kfd-->kgd interface. The patch removes the function from the interface file and from the interface declaration file. The function initializes memory apertures to fixed base/limit address and non cached memory types.

drm/radeon: Add radeon <--> amdkfd interface 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. Move generic kfd-->kgd interface and other generic kgd definitions to a generic header file that will be used by AMD's radeon and amdgpu drivers Signed-off-by: Oded Gabbay <oded.gabbay@amd.com>
