Detailed Description

Screen, Adapter or GPU.

These are driver functions/facilities that are context independent. Gallium screen/adapter context. Basically everything hardware-specific that doesn't actually require a rendering context.

Field Documentation

struct pipe_winsys* pipe_screen::winsys [read]

Definition at line 56 of file p_screen.h.

void(* pipe_screen::destroy)(struct pipe_screen *)

const char*(* pipe_screen::get_name)(struct pipe_screen *)

const char*(* pipe_screen::get_vendor)(struct pipe_screen *)

int(* pipe_screen::get_param)(struct pipe_screen *, int param)

Query an integer-valued capability/parameter/limit.

Parameters:

param

one of PIPE_CAP_x

float(* pipe_screen::get_paramf)(struct pipe_screen *, int param)

Query a float-valued capability/parameter/limit.

Parameters:

param

one of PIPE_CAP_x

boolean(* pipe_screen::is_format_supported)(struct pipe_screen *, enum pipe_format format, enum pipe_texture_target target, unsigned tex_usage, unsigned geom_flags)

Check if the given pipe_format is supported as a texture or drawing surface.

Parameters:

	tex_usage	bitmask of PIPE_TEXTURE_USAGE_*
	flags	bitmask of PIPE_TEXTURE_GEOM_*

struct pipe_texture*(* pipe_screen::texture_create)(struct pipe_screen *, const struct pipe_texture *templat) [read]

Create a new texture object, using the given template info.

struct pipe_texture*(* pipe_screen::texture_blanket)(struct pipe_screen *, const struct pipe_texture *templat, const unsigned *pitch, struct pipe_buffer *buffer) [read]

Create a new texture object, using the given template info, but on top of existing memory.

It is assumed that the buffer data is layed out according to the expected by the hardware. NULL will be returned if any inconsistency is found.

void(* pipe_screen::texture_release)(struct pipe_screen *, struct pipe_texture **pt)

struct pipe_surface*(* pipe_screen::get_tex_surface)(struct pipe_screen *, struct pipe_texture *texture, unsigned face, unsigned level, unsigned zslice, unsigned usage) [read]

Get a surface which is a "view" into a texture.

void(* pipe_screen::tex_surface_release)(struct pipe_screen *, struct pipe_surface **)

void*(* pipe_screen::surface_map)(struct pipe_screen *, struct pipe_surface *surface, unsigned flags)

void(* pipe_screen::surface_unmap)(struct pipe_screen *, struct pipe_surface *surface)
