* ``PIPE_CAP_TEXTURE_BUFFER_OFFSET_ALIGNMENT``: Describes the required
alignment for pipe_sampler_view::u.buf.first_element, in bytes.
If a driver does not support first/last_element, it should return 0.
+* ``PIPE_CAP_BUFFER_SAMPLER_VIEW_RGBA_ONLY``: Whether the driver only
+ supports R, RG, RGB and RGBA formats for PIPE_BUFFER sampler views.
+ When this is the case it should be assumed that the swizzle parameters
+ in the sampler view have no effect.
* ``PIPE_CAP_TGSI_TEXCOORD``: This CAP describes a hw limitation.
If true, the hardware cannot replace arbitrary shader inputs with sprite
coordinates and hence the inputs that are desired to be replaceable must
view it is intended to be used with, or herein undefined results may occur
for permutational swizzles.
* ``PIPE_CAP_MAX_TEXTURE_BUFFER_SIZE``: The maximum accessible size with
- a buffer sampler view, in bytes.
+ a buffer sampler view, in texels.
* ``PIPE_CAP_MAX_VIEWPORTS``: The maximum number of viewports (and scissors
since they are linked) a driver can support. Returning 0 is equivalent
to returning 1 because every driver has to support at least a single
* ``PIPE_CAP_TGSI_FS_FACE_IS_INTEGER_SYSVAL``: If state trackers should use
a system value for the FACE fragment shader input.
Also, the FACE system value is integer, not float.
+* ``PIPE_CAP_SHADER_BUFFER_OFFSET_ALIGNMENT``: Describes the required
+ alignment for pipe_shader_buffer::buffer_offset, in bytes. Maximum
+ value allowed is 256 (for GL conformance). 0 is only allowed if
+ shader buffers are not supported.
+* ``PIPE_CAP_INVALIDATE_BUFFER``: Whether the use of ``invalidate_resource``
+ for buffers is supported.
+* ``PIPE_CAP_GENERATE_MIPMAP``: Indicates whether pipe_context::generate_mipmap
+ is supported.
+* ``PIPE_CAP_STRING_MARKER``: Whether pipe->emit_string_marker() is supported.
+* ``PIPE_CAP_SURFACE_REINTERPRET_BLOCKS``: Indicates whether
+ pipe_context::create_surface supports reinterpreting a texture as a surface
+ of a format with different block width/height (but same block size in bits).
+ For example, a compressed texture image can be interpreted as a
+ non-compressed surface whose texels are the same number of bits as the
+ compressed blocks, and vice versa. The width and height of the surface is
+ adjusted appropriately.
+* ``PIPE_CAP_QUERY_BUFFER_OBJECT``: Driver supports
+ context::get_query_result_resource callback.
+* ``PIPE_CAP_PCI_GROUP``: Return the PCI segment group number.

+* ``PIPE_CAP_PCI_DEVICE``: Return the PCI device number.
+* ``PIPE_CAP_PCI_FUNCTION``: Return the PCI function number.
.. _pipe_capf:
(also used to implement atomic counters). Having this be non-0 also
implies support for the ``LOAD``, ``STORE``, and ``ATOM*`` TGSI
opcodes.
+* ``PIPE_SHADER_CAP_SUPPORTED_IRS``: Supported representations of the
+ program. It should be a mask of ``pipe_shader_ir`` bits.
+* ``PIPE_SHADER_CAP_MAX_SHADER_IMAGES``: Maximum number of image units.
.. _pipe_compute_cap:
``processor-arch-manufacturer-os`` that will be passed on to the compiler.
This CAP is only relevant for drivers that specify PIPE_SHADER_IR_LLVM
or PIPE_SHADER_IR_NATIVE for their preferred IR.
