Hello Greg,
This is the pull request for habanalabs driver for kernel 5.5.
It mainly contains improvements to MMU and reset code, and exposes more information through our INFO IOCTL.
Please see the tag message for more details on what this pull request contains.
Thanks, Oded

habanalabs: add more protection of device during reset (2019-11-21 11:35:47 +0200)
---------------------------------------------------------------- This tag contains the following changes for kernel 5.5:
- MMU code improvements that includes: - Distinguish between "normal" unmapping and unmapping that is done as part of the tear-down of a user process. This improves performance of unmapping during reset of the device. - Add future ASIC support in generic MMU code.
- Improve device reset code by adding more protection around accessing the device during the reset process.
- Add new H/W queue type for future ASIC support
- Add more information to be retrieved by users through INFO IOCTL: - clock rate - board name - reset counters
- Small bug fixes and minor improvements to code.
---------------------------------------------------------------- Moti Haimovski (1): habanalabs: expose reset counters via existing INFO IOCTL
Oded Gabbay (16): habanalabs: handle F/W failure for sensor initialization habanalabs: set TPC Icache to 16 cache lines habanalabs: add opcode to INFO IOCTL to return clock rate habanalabs: expose card name in INFO IOCTL habanalabs: read F/W versions before failure habanalabs: use registers name defines for ETR block habanalabs: set ETR as non-secured habanalabs: increase max jobs number to 512 habanalabs: don't print error when queues are full habanalabs: export uapi defines to user-space habanalabs: remove prints on successful device initialization habanalabs: use defines for F/W files habanalabs: make code more concise habanalabs: make the reset code more consistent habanalabs: flush EQ workers in hard reset habanalabs: add more protection of device during reset
Omer Shpigelman (9): habanalabs: re-factor memory module code habanalabs: type specific MMU cache invalidation habanalabs: re-factor MMU masks and documentation habanalabs: split MMU properties to PCI/DRAM habanalabs: prevent read/write from/to the device during hard reset habanalabs: optimize MMU unmap habanalabs: skip VA block list update in reset flow habanalabs: invalidate MMU cache only once habanalabs: remove unnecessary checks
Tomer Tayar (3): habanalabs: Fix typos habanalabs: Mark queue as expecting CB handle or address habanalabs: Add a new H/W queue type
