91204e4703 accel/habanalabs: fix handling of arc farm sei event
There is only single eq entry for arc farm sei event which aggregates
events from the four arc farms.
Fix the code to handle this event according to this behavior.

e1ef053e08 accel/habanalabs: add handling for unexpected user event
In order for the user to be aware of unexpected events in Gaudi2 that
aren't assigned to a specific engine, we are adding the handling of
this dedicated interrupt.

f7f0085eec accel/habanalabs: add uapi to stall/resume engine
The user might want to stall/resume engines to perform power testing
for various scenarios. Because our current
HL_CS_FLAGS_ENGINE_CORE_COMMAND command only handles the engines' cores,
we need to add another opcode for handling entire engine and not just
its core.

The user supplies an array, where each entry holds the engine's ID and
the command to send to the engine. The size of the array is limited
by the number of engines in the ASIC (only Gaudi2 is currently
supported).

f7d67c1cfd habanalabs/gaudi2: find decode error root cause
When a decode error happens, we often don't know the exact root
cause (the erroneous address that was accessed) and the exact engine
that created the erroneous transaction.

To find out, we need to go over all the relevant register blocks
in the ASIC. Once we find the relevant engine, we print its details
and the offending address.

This helps tremendously when debugging an error that was created
by running a user workload.

7d352a8160 habanalabs: Replace zero-length arrays with flexible-array members
Zero-length arrays are deprecated[1] and we are moving towards
adopting C99 flexible-array members instead. So, replace zero-length
arrays in a couple of structures with flex-array members.

This helps with the ongoing efforts to tighten the FORTIFY_SOURCE
routines on memcpy() and help us make progress towards globally
enabling -fstrict-flex-arrays=3 [2].

20faaeec37 habanalabs: add uapi to flush inbound HBM transactions
When doing p2p with a NIC device, the NIC needs to make sure all the
writes to the HBM (through the PCI bar of the Gaudi device) were
flushed.

It can be done by either the NIC or the host reading through the PCI
bar.

To support the host side, we supply a simple uapi to perform this flush
through the driver, because the user can't create such a transaction
by itself (the PCI bar isn't exposed to normal users).

e65e175b07 habanalabs: move driver to accel subsystem
Now that we have a subsystem for compute accelerators, move the
habanalabs driver to it.

This patch only moves the files and fixes the Makefiles. Future
patches will change the existing code to register to the accel
subsystem and expose the accel device char files instead of the
habanalabs device char files.

Update the MAINTAINERS file to reflect this change.
