Merge tag 'misc-habanalabs-next-2019-09-05' of git://people.freedesktop.org/~gabbayo/linux into char-misc-next
Oded writes:
This tag contains the following changes for kernel 5.4:
- Create an additional char device per PCI device. The new char device
allows any application to query the device for stats, information, idle
state and more. This is needed to support system/monitoring
applications, while also allowing the deep-learning application to send
work to the ASIC through the main (original) char device.
- Fix possible kernel crash in case user supplies a smaller-than-required
buffer to the DEBUG IOCTL.
- Expose the device to userspace only after initialization was done, to
prevent a race between the initialization and user submitting workloads.
- Add uapi, as part of INFO IOCTL, to allow user to query the device
utilization rate.
- Add uapi, as part of INFO IOCTL, to allow user to retrieve aggregate H/W
events, i.e. counting H/W events from the loading of the driver.
- Register to the HWMON subsystem with the board's name, to allow the
user to prepare a custom sensor file per board.
- Use correct macros for endian swapping.
- Improve error printing in multiple places.
- Small bug fixes.
