gallium: add PIPE_CAP_TGSI_ARRAY_COMPONENTS

2016-10-12T16:50:10+00:00

This is a screen cap because drivers are expected to support it either
for all shader types or for none of them.

gallium: add a cap to expose whether driver supports mixed color/zs bits

2016-08-23T22:30:49+00:00

Some hardware can't render to color/depth buffers of mixed bitness. When
that happens a fallback has to happen, but this allows the driver to
express that this isn't an optimal scenario. The purpose of this is to
remove such fbconfigs from the GLX/EGL config list.

gallium: change pipe_sampler_view::first_element/last_element -> offset/size

2016-08-17T12:15:33+00:00

This is required by OpenGL. Our hardware supports this.

Example: Bind RGBA32F with offset = 4 bytes.

gallium: add a cap for VIEWPORT_SUBPIXEL_BITS (v2)

2016-07-20T10:45:31+00:00

This allows Gallium drivers to advertise the subpixel precision
for floating point viewports bounds.

v2:
  - Set ViewportSubpixelBits in st_init_limits.

gallium: Add a cap for offset_units_unscaled

2016-06-25T08:16:15+00:00

D3D9 has a different behaviour for depth bias.

For OGL/D3D1X, the depth bias unit is the
minimal resolvable value for the depth buffer,
which depends on the format (and has different
behaviour for float depth buffers).

For D3D9, the depth bias unit is 1.0f.

gallium: add PIPE_CAP_MAX_WINDOW_RECTANGLES to all drivers

2016-06-18T17:38:29+00:00

This says how many window rectangles are supported by the
implementation, although it may not exceed PIPE_MAX_WINDOW_RECTANGLES.
