2019-11-21habanalabs: export uapi defines to user-spaceOded Gabbay
The two defines that control the maximum size of a command buffer and the maximum number of JOBS per CS need to be exported to the user as they are part of the API towards user-space. Signed-off-by: Oded Gabbay <oded.gabbay@gmail.com> Reviewed-by: Omer Shpigelman <oshpigelman@habana.ai>

2019-11-21habanalabs: increase max jobs number to 512Oded Gabbay
In training, there is a need for a large amount of patching to the recipe. This results in many command buffers contains a lot of DMA packets. The number of command buffers per CS is larger than the current maximum of 64, which is an arbitrary number that is enough for inference, but it has no real affect on the code and/or resources of the host machine.

2019-11-21habanalabs: Add a new H/W queue typeTomer Tayar
This patch adds a support for a new H/W queue type. This type of queue is for DMA and compute engines jobs, for which completion notification are sent by H/W. Command buffer for this queue can be created either through the CB IOCTL and using the retrieved CB handle, or by preparing a buffer on the host or device SRAM/DRAM, and using the device address to that buffer. The patch includes the handling of the 2 options, as well as the initialization of the H/W queue and its jobs scheduling.

2019-11-21habanalabs: Mark queue as expecting CB handle or addressTomer Tayar
Jobs on some queues must be provided with a handle to a driver command buffer object, while for other queues, jobs must be provided with an address to a command buffer. Currently the distinction is done based on the queue type, which is less flexible if the same queue type behaves differently on different types of ASICs. This patch adds a new queue property for this target, which is configured per queue type per ASIC type.

2019-10-23compat_ioctl: use correct compat_ptr() translation in driversArnd Bergmann
A handful of drivers all have a trivial wrapper around their ioctl handler, but don't call the compat_ptr() conversion function at the moment. In practice this does not matter, since none of them are used on the s390 architecture and for all other architectures, compat_ptr() does not do anything, but using the new compat_ptr_ioctl() helper makes it more correct in theory, and simplifies the code. I checked that all ioctl handlers in these files are compatible and take either pointer arguments or no argument.

2019-10-23compat_ioctl: move more drivers to compat_ptr_ioctlArnd Bergmann
The .ioctl and .compat_ioctl file operations have the same prototype so they can both point to the same function, which works great almost all the time when all the commands are compatible. One exception is the s390 architecture, where a compat pointer is only 31 bit wide, and converting it into a 64-bit pointer requires calling compat_ptr(). Most drivers here will never run in s390, but since we now have a generic helper for it, it's easy enough to use it consistently. I double-checked all these drivers to ensure that all ioctl arguments are used as pointers or are ignored, but are not interpreted as integer values.
