Oded writes:
This tag contains habanalabs driver changes for v5.16:
- Add a new uAPI (under the memory ioctl) to request from the driver
to export a DMA-BUF object that represents a memory region on
the device's DRAM. This is needed to enable peer-to-peer over PCIe
between habana device and an RDMA adapter (e.g. mlnx5 or efa
rdma adapter).
- Add debugfs node to dynamically configure CS timeout. Up until now,
it was only configurable through kernel module parameter.
- Fetch more comprehensive power information from the firmware.
- Always take timestamp when waiting for user interrupt, as the user
needs that information to optimize the graph runtime compilation.
- Modify user interrupt to look on 64-bit user value as fence, instead
of 32-bit.
- Bypass reset in case of repeated h/w error event after device reset.
This is to prevent endless loop of resets to the device.
- Fix several bugs in multi CS completion code.
- Fix race condition in fd close/open.
- Update to latest firmware headers
- Add select CRC32 in kconfig
- Small fixes, cosmetics
