Oded Gabbay 6476b47243 habanalabs: set ETR as non-secured
ETR should always be non-secured as it is used by the users to record
profiling/trace data.

Oded Gabbay e1a84d56fc habanalabs: use registers name defines for ETR block
We have a single ETR block in the SOC, so use explicit register
name defines for initializing this block. This makes it more readable and
maintainable.

Oded Gabbay 75b3cb2bb0 habanalabs: add uapi to retrieve device utilization
Users and sysadmins usually want to know what is the device utilization as
a level 0 indication if they are efficiently using the device.

Add a new opcode to the INFO IOCTL that will return the device utilization
over the last period of 100-1000ms. The return value is 0-100,
representing as percentage the total utilization rate.

Tomer Tayar 4095a17657 habanalabs: Add descriptive names to PSOC scratch-pad registers
The PSOC scratch-pad registers are used for communication with the
device CPU. This patch adds new definitions for these registers which
are more descriptive than their general names.

The new set of definitions also gathers and documents the current usage
of the scratch-pad registers by the driver and the device CPU.

Ben Segal 213ad5ad01 habanalabs: fix endianness handling for packets from user
Packets that arrive from the user and need to be parsed by the driver are
assumed to be in LE format.

This patch fix all the places where the code handles these packets and use
the correct endianness macros to handle them, as the driver handles the
packets in CPU format (LE or BE depending on the arch).

Tomer Tayar ac6183ae4b habanalabs: Update the device idle check
The patch updates the device idle check:
- Add reading the DMA core status register, because it is possible that
  a QMAN has finished its work but the DMA itself is still running.
- Remove the MME shadow status check, as the MME ARCH status register
  includes the status of all MME shadows.

Omer Shpigelman 8ba2876ddf habanalabs: add goya implementation for debug configuration
This patch adds the ASIC-specific function for GOYA to configure the
coresight components.

Most of the components have an enabled/disabled flag, depending on whether
the user wants to enable the component or disable it.

For some of the components, such as ETR and SPMU, the user can also
request to read values from them. Those values are needed for the user to
parse the trace data.

The ETR configuration is also checked for security purposes, to make sure
the trace data is written to the device's DRAM.

Oded Gabbay 9494a8dd8d habanalabs: add h/w queues module
This patch adds the H/W queues module and the code to initialize Goya's
various compute and DMA engines and their queues.

Goya has 5 DMA channels, 8 TPC engines and a single MME engine. For each
channel/engine, there is a H/W queue logic which is used to pass commands
from the user to the H/W. That logic is called QMAN.

There are two types of QMANs: external and internal. The DMA QMANs are
considered external while the TPC and MME QMANs are considered internal.
For each external queue there is a completion queue, which is located on
the Host memory.

The differences between external and internal QMANs are:

1. The location of the queue's memory. External QMANs are located on the
   Host memory while internal QMANs are located on the on-chip memory.

2. The external QMAN write an entry to a completion queue and sends an
   MSI-X interrupt upon completion of a command buffer that was given to
   it. The internal QMAN doesn't do that.
