- New feature of graceful hard-reset. Instead of immediately killing the
user-process when a command submission times out, we wait a bit and give
the user-process notification and let it try to close things gracefully,
with the ability to retrieve debug information.
- Enhance the EventFD mechanism. Add new events such as access to illegal
address (RAZWI), page fault, device unavailable. In addition, change the
event workqueue to be handled in a single-threaded workqueue.
- Allow the control device to work during reset of the ASIC, to enable
monitoring applications to continue getting the data.
- Add handling for Gaudi2 with PCI revision 2.
- Reduce severity of prints due to power/thermal events.
- Change how we use the h/w to perform memory scrubbing in Gaudi2.
- Multiple bug fixes, refactors and renames.
