      habanalabs: Manipulate DMA addresses in ASIC functions · 94cb669c
      由 Tomer Tayar 提交于 
      Routing device accesses to the host memory requires the usage of a base
offset, which is canceled by the iATU just before leaving the device.
The value of the base offset might be distinctive between different ASIC
types.
The manipulation of the addresses is currently used throughout the
driver code, and one should be aware to it whenever providing a host
memory address to the device.
This patch removes this manipulation from the driver common code, and
moves it to the ASIC specific functions that are responsible for
host memory allocation/mapping.

      habanalabs: rename functions to improve code readability · d9c3aa80
      由 Oded Gabbay 提交于 
      This patch renames four functions in the ASIC-specific functions section,
so it will be easier to differentiate them from the generic kernel
functions with the same name.

This will help in future code reviews, to make sure we don't use the
kernel functions directly.

      habanalabs: Use single pool for CPU accessible host memory · 03d5f641
      由 Tomer Tayar 提交于 
      The device's CPU accessible memory on host is managed in a dedicated
pool, except for 2 regions - Primary Queue (PQ) and Event Queue (EQ) -
which are allocated from generic DMA pools.
Due to address length limitations of the CPU, the addresses of all these
memory regions must have the same MSBs starting at bit 40.
This patch modifies the allocation of the PQ and EQ to be also from the
dedicated pool, to ensure compliance with the limitation.

      habanalabs: return old dram bar address upon change · a38693d7
      由 Oded Gabbay 提交于 
      This patch changes the ASIC interface function that changes the DRAM bar
window. The change is to return the old address that the DRAM bar pointed
to instead of an error code.

This simplifies the code that use this function (mainly in debugfs) to
restore the bar to the old setting.

This is also needed for easier support in future ASICs.

      habanalabs: use ASIC functions interface for rreg/wreg · b2377e03
      由 Oded Gabbay 提交于 
      This patch slightly changes the macros of RREG32 and WREG32, which are
used when reading or writing from registers.

Instead of directly calling a function in the common code from these
macros, the new code calls a function from the ASIC functions interface.

This change allows us to share much more code between real ASICs and
simulators, which in turn reduces the maintenance burden and
the chances for forgetting to port code between the ASIC files.

The patch also implements the hl_poll_timeout macro, instead of calling
the generic readl_poll_timeout macro. This is required to allow use of
this macro in the simulator files.

As a result from this change, more functions in goya.c are shared with the
simulator and therefore, should not be defined as static.
