Eleni Maria Stea 983cebb5d2 anv: Implement physical device properties for VK_EXT_sample_locations
The VkPhysicalDeviceSampleLocationPropertiesEXT struct is filled with
implementation dependent values and according to the table from the
Vulkan Specification section [36.1. Limit Requirements]:

pname | max | min
pname:sampleLocationSampleCounts   |-            |ename:VK_SAMPLE_COUNT_4_BIT
pname:maxSampleLocationGridSize    |-            |(1, 1)
pname:sampleLocationCoordinateRange|(0.0, 0.9375)|(0.0, 0.9375)
pname:sampleLocationSubPixelBits   |-            |4
pname:variableSampleLocations      | true        |implementation dependent

The hardware only supports setting the same sample location for all the
pixels, so we only support 1x1 grids.

Also, variableSampleLocations is set to true because we can set sample
locations per draw.

Implement the vkGetPhysicalDeviceMultisamplePropertiesEXT according to
the Vulkan Specification section [36.2. Additional Multisampling
Capabilities].

v2: 1- Replaced false with VK_FALSE for consistency. (Sagar Ghuge)
    2- Used the isl_device_sample_count to take the number of samples
    per platform to avoid extra checks. (Sagar Ghuge)

v3: 1- Replaced VK_FALSE with false as Jason has sent a patch to replace
    VK_FALSE with false in other places. (Jason Ekstrand)
    2- Removed unecessary defines and set the grid size to 1 (Jason Ekstrand)

v4: Fix properties reporting in GetPhysicalDeviceProperties2, not
    GetPhysicalDeviceFeatures2 (Lionel)
    Use same alignment as other functions (Lionel)
    Report variableSampleLocations=true (Lionel)

v5: Don't overwrite the pNext in GetPhysicalDeviceMultisamplerPropertiesEXT

Source
------

This repository lives at https://gitlab.freedesktop.org/mesa/mesa.
Other repositories are likely forks, and code found there is not supported.


Build & install
---------------

You can find more information in our documentation (`docs/install.rst
<https://mesa3d.org/install.html>`_), but the recommended way is to use
Meson (`docs/meson.rst <https://mesa3d.org/meson.html>`_):

.. code-block:: sh

  $ mkdir build
  $ cd build
  $ meson ..
  $ sudo ninja install


Support
-------

Many Mesa devs hang on IRC; if you're not sure which channel is
appropriate, you should ask your question on `Freenode's #dri-devel
<irc://chat.freenode.net#dri-devel>`_, someone will redirect you if
necessary.
Remember that not everyone is in the same timezone as you, so it might
take a while before someone qualified sees your question.
To figure out who you're talking to, or which nick to ping for your
question, check out `Who's Who on IRC
