habanalabs: add skeleton driver This patch adds the habanalabs skeleton driver. The driver does nothing at this stage except very basic operations. It contains the minimal code to insmod and rmmod the driver and to create a /dev/hlX file per PCI device.

habanalabs: add command buffer module This patch adds the command buffer (CB) module, which allows the user to create and destroy CBs and to map them to the user's process address-space. A command buffer is a memory blocks that reside in DMA-able address-space and is physically contiguous so it can be accessed by the device without MMU translation. The command buffer memory is allocated using the coherent DMA API. When creating a new CB, the IOCTL returns a handle of it, and the user-space process needs to use that handle to mmap the buffer to get a VA in the user's address-space. Before destroying (freeing) a CB, the user must unmap the CB's VA using the CB handle. Each CB has a reference counter, which tracks its usage in command submissions and also its mmaps (only a single mmap is allowed). The driver maintains a pool of pre-allocated CBs in order to reduce latency during command submissions. In case the pool is empty, the driver will go to the slow-path of allocating a new CB, i.e. calling dma_alloc_coherent.

habanalabs: add command submission module This patch adds the main flow for the user to submit work to the device. Each work is described by a command submission object (CS). The CS contains 3 arrays of command buffers: One for execution, and two for context-switch (store and restore). For each CB, the user specifies on which queue to put that CB. In case of an internal queue, the entry doesn't contain a pointer to the CB but the address in the on-chip memory that the CB resides at. The driver parses some of the CBs to enforce security restrictions. The user receives a sequence number that represents the CS object. The user can then query the driver regarding the status of the CS, using that sequence number. In case the CS doesn't finish before the timeout expires, the driver will perform a soft-reset of the device.

habanalabs: add debugfs support This patch adds debugfs support to the driver. It allows the user-space to display information that is contained in the internal structures of the driver, such as: - active command submissions - active user virtual memory mappings - number of allocated command buffers It also enables the user to perform reads and writes through Goya's PCI bars.
