Subject: [git pull] habanalabs pull request for kernel 5.14
Hi Greg,
This is habanalabs pull request for the merge window of kernel 5.14.
The bulk of the commits relate to improvements of the communication
between the driver and the firmware that is running inside the ASIC.
There are also many small changes, new debug features, improvements, etc.
Details are in the tag.
Thanks,
Oded

habanalabs/gaudi: refactor hard-reset related code (2021-06-21 10:21:51 +0300)
----------------------------------------------------------------
This tag contains habanalabs driver changes for v5.14:
- Change communication protocol with f/w. The new protocl allows better
backward compatibility between different f/w versions and is more
stable.
- Send hard-reset cause to f/w after a hard-reset has happened.
- Move to indirection when generating interrupts to f/w.
- Better progress and error messages during the f/w load stage.
- Recognize that f/w is with enabled security according to device ID.
- Add validity check to event queue mechanism.
- Add new event from f/w that will indicate a daemon has been terminated
inside the f/w.
- Move to TLB cache range invalidation in the device's MMU.
- Disable memory scrubbing by default for performance.
- Many fixes for sparse/smatch reported errors.
- Enable by default stop-on-err in the ASIC.
- Move to ASYNC device probing to speedup loading of driver in server
with multiple devices.
- Fix to stop using disabled NIC ports when doing collective operation.
- Use standard error codes instead of positive values.
- Add support for resetting device after user has finished using it.
- Add debugfs option to avoid reset when a CS has got stuck.
- Add print of the last 8 CS pointers in case of error in QMANs.
- Add statistics on opening of the FD of a device.
