amdkfd: Add amdkfd skeleton driver This patch adds the amdkfd skeleton driver. The driver does nothing except define a /dev/kfd device. It returns -ENODEV on all amdkfd IOCTLs. v3: Move bool field to the end of structure, removed the pmc ioctls and added a meaningful error message for ioctl error. v5: Create a new folder drm/amd and move amdkfd from drm/radeon/ to drm/amd/ Remove scheduler_class from kfd_priv.h as it was never used Add skeleton implementation of the Get Version IOCTL v6: Update module version to the correct number and remove the "default m" from the Kconfig file Signed-off-by: Oded Gabbay <oded.gabbay@amd.com>

amdkfd: Add basic modules to amdkfd This patch adds the process module and three helper modules: - kfd_process, which handles process which open /dev/kfd - kfd_doorbell, which provides helper functions for doorbell allocation, release and mapping to userspace - kfd_pasid, which provides helper functions for pasid allocation and release - kfd_aperture, which provides helper functions for managing the LDS, Local GPU memory and Scratch memory apertures of the process This patch only contains the basic kfd_process module, which doesn't contain the reference to the queue scheduler. This was done to allow easier code review. Also, this patch doesn't contain the calls to the IOMMU driver for binding the pasid to the device. Again, this was done to allow easier code review The kfd_process object is created when a process opens /dev/kfd and is closed when the mm_struct of that process is teared-down. v3: Removed kfd_vidmem.c file Replaced direct mmput call to mmu_notifier release Removed typedefs Moved bool field to end of the structure Added new kernel params for gart usage limitation Added initialization of sa manager Fixed debug messages Remove support for LDS in 32 bit Changed code to support mmap of doorbell pages from userspace Added documentation for apertures v4: Replaced RCU by SRCU for kfd_process list management v5: Move amdkfd from drm/radeon/ to drm/amd/ Rename kfd_aperture.c to kfd_flat_memory.c Protect against multiple init calls MQD size is H/W dependent so moved it to device info structure Rename kfd_mem_obj structure's members Use delayed function for process tear-down Signed-off-by: Oded Gabbay <oded.gabbay@amd.com>

amdkfd: Add kernel queue module The kernel queue module enables the amdkfd to establish kernel queues, not exposed to user space. The kernel queues are used for HIQ (HSA Interface Queue) and DIQ (Debug Interface Queue) operations v3: Removed use of internal typedefs and added use of the new gart allocation functions v4: Fixed a miscalculation in kernel queue wrapping v5: Move amdkfd from drm/radeon/ to drm/amd/ Change format of mqd structure to match latest KV firmware Add support for AQL queues creation to enable working with open-source HSA runtime Add define for kernel queue size Various fixes Signed-off-by: Ben Goz <ben.goz@amd.com> Signed-off-by: Oded Gabbay <oded.gabbay@amd.com>

amdkfd: Add process queue manager module The queue scheduler divides into two sections, one section is process bounded and the other section is device bounded. The process bounded section is handled by this module. The PQM handles usermode queue setup, updates and tear-down. v3: Used kernel parameter to limit queues per process instead of define Added use of doorbell address from user v4: Modified pqm_create_queue so that only when creating usermode queues the driver should return the queue properties to the userspace. Added an info message print when no more queues can be opened because of the queue per process limitation v5: Move amdkfd from drm/radeon/ to drm/amd/ Various fixes Signed-off-by: Ben Goz <ben.goz@amd.com> Signed-off-by: Oded Gabbay <oded.gabbay@amd.com>

amdkfd: Add interrupt handling module This patch adds the interrupt handling module, in kfd_interrupt.c, and its related members in different data structures to the amdkfd driver. The amdkfd interrupt module maintains an internal interrupt ring per amdkfd device. The internal interrupt ring contains interrupts that needs further handling. The extra handling is deferred to a later time through a workqueue. There's no acknowledgment for the interrupts we use. The hardware simply queues a new interrupt each time without waiting. The fixed-size internal queue means that it's possible for us to lose interrupts because we have no back-pressure to the hardware. v3: Move amdkfd from drm/radeon/ to drm/amd/ Change device init Made sure spin lock is taken only if init is complete Moved bool field to the end of the structure Signed-off-by: Andrew Lewycky <Andrew.Lewycky@amd.com> Signed-off-by: Oded Gabbay <oded.gabbay@amd.com>
