Hi Greg,
This is habanalabs pull request for the merge window of kernel 5.15.
The commits divide roughly 50/50 between adding new features, such
as peer-to-peer support with DMA-BUF or signaling from within a graph,
and fixing various bugs, small improvements, etc.
Full details are in the tag.
Thanks,
Oded

habanalabs/gaudi: invalidate PMMU mem cache on init (2021-08-19 11:43:43 +0300)
----------------------------------------------------------------
This tag contains habanalabs driver changes for v5.15:
- 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 adapter).
- Add a new uAPI (under the cs ioctl) to enable to user to reserve
signals and signal them from within its workloads, while the driver
performs the waiting. This allows finer granularity of pipelining
between the different engines and resource utilization.
- Add a new uAPI (under the wait_for_cs ioctl) to allow waiting
on multiple command submissions (workloads) at the same time. This
is an optimization for the user process so it won't need to call
multiple times to the wait_for_cs ioctl.
- Add new feature of "state dump", which can be triggered through new
debugfs node. This is a similar concept to the kernel panic dump.
This new mechanism retrieves information from the device in case
one of the workloads that was sent by the user got stuck. This is
very helpful for debugging the hang.
- Add a new debugfs node to perform lookup of user pointers that are
mapped to habana device's pmmu.
- Fix to the tracking of user process when running inside a container.
- Allow user to map more than 4GB of memory to the device MMU in single
IOCTL call.
- Minimize number of register reads done in GAUDI during user operation.
- Allow user to retrieve the device's server type that the device is
connected to.
- Several fixes to the code of waiting on interrupts on behalf of the
user.
- Fixes and improvements to the hint mechanism in our VA allocation.
- Update the firmware header files to the latest version while
maintaining backward compatibility with older firmware versions.
- Multiple fixes to various bugs.
