- Add support to reset device after the user closes the file descriptor.
Because we support a single user, we can reset the device (if needs to)
after a user closes its file descriptor to make sure the device is in
idle and clean state for the next user.
- Add a new feature to allow the user to wait on interrupt. This is needed
for future ASICs
- Replace GFP_ATOMIC with GFP_KERNEL wherever possible and add code to
support failure of allocating with GFP_ATOMIC.
- Update code to support the latest firmware image:
- More security features are done in the firmware
- Remove hard-coded assumptions and replace them with values that are
sent to the firmware on loading.
- Print device unusable error
- Reset device in case the communication between driver and firmware
gets out of sync.
- Support new PCI device ids for secured GAUDI.
- Expose current power draw through the INFO IOCTL.
- Support resetting the device upon a request from the BMC (through F/W).
- Always use only a single MSI in GAUDI, due to H/W limitation.
- Improve data-path code by taking out code from spinlock protection.
- Allow user to specify custom timeout per Command Submission.
- Some enhancements to debugfs.
- Various minor changes and improvements.
