This tag contains additional habanalabs driver changes for v6.5:
- uAPI changes:
- Return 0 when user queries if there was a h/w or f/w error and no such error happened.
Previously we returned an error in such case.
- New features and improvements:
- Add pci health check when we lose connection with the firmware. This can be used to
distinguish between pci link down and firmware getting stuck.
- Add more info to the error print when TPC interrupt occur.
- Reduce amount of code under mutex in the command submission of signal event.
- Firmware related fixes:
- Fixes to the handshake protocol during f/w initialization.
- Display information that the f/w sends us when encountering a DMA error.
- Do soft-reset using a message sent to firmware instead of writing to MMIO.
- Prepare generic code to extract f/w version numbers.
- Bug fixes and code cleanups. Notable fixes are:
- Unsecure certain TPC registers that the user should access.
- Fix handling of QMAN errors
- Fix memory leak when recording errors (to later pass them to the user)
- Multiple fixes to razwi interrupt handling code
accel/habanalabs: refactor error info reset
Moved error info reset code to single function for future use from
other places in the driver.
