Shashank Sharma defb41e8ef drm/amdgpu: create context space for usermode queue
The MES FW expects us to allocate at least one page as context
space to process gang and process related context data. This
patch creates a joint object for the same, and calculates GPU
space offsets of these spaces.

V1: Addressed review comments on RFC patch:
    Alex: Make this function IP specific

V2: Addressed review comments from Christian
    - Allocate only one object for total FW space, and calculate
      offsets for each of these objects.

V3: Integration with doorbell manager

V4: Review comments:
    - Remove shadow from FW space list from cover letter (Alex)
    - Alignment of macro (Luben)

V5: Merged patches 5 and 6 into this single patch
    Addressed review comments:
    - Use lower_32_bits instead of mask (Christian)
    - gfx_v11_0 instead of gfx_v11 in function names (Alex)
    - Shadow and GDS objects are now coming from userspace (Christian,
      Alex)

V6:
    - Add a comment to replace amdgpu_bo_create_kernel() with
      amdgpu_bo_create() during fw_ctx object creation (Christian).
    - Move proc_ctx_gpu_addr, gang_ctx_gpu_addr and fw_ctx_gpu_addr out
      of generic queue structure and make it gen11 specific (Alex).

V7:
   - Using helper function to create/destroy userqueue objects.
   - Removed FW object space allocation.

V8:
   - Updating FW object address from user values.

V9:
   - uppdated function name from gfx_v11_* to mes_v11_*

V10:
   - making this patch independent of IP based changes, moving any
     GFX object related changes in GFX specific patch (Alex)

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
