2022-02-28habanalabs/gaudi: disable CGM permanentlyOded Gabbay6-221/+66
Due to the need of SynapseAI to configure all TPC engines from a single QMAN, the driver must disable CGM and never allow the user to enable it. Otherwise, the configuration of the TPC engines will fail. Signed-off-by: Oded Gabbay <[email protected]>
2022-02-28habanalabs: fix possible memory leak in MMU DR finiOhad Sharabi1-1/+1
This patch fixes what seems to be copy paste error. We will have a memory leak if the host-resident shadow is NULL (which will likely happen as the DR and HR are not dependent).

A temperature transducer is a device that converts a thermal quantity into any other physical quantity.

The iio-rescale driver supports various combinations of scale types and offsets. These can often result in large integer multiplications.
