2009-03-04gallium: Unify reference counting.Michel Dänzer
The core reference counting code is centralized in p_refcnt.h. This has some consequences related to struct pipe_buffer: * The screen member of struct pipe_buffer must be initialized, or pipe_buffer_reference() will crash trying to destroy a buffer with reference count 0. u_simple_screen takes care of this, but I may have missed some of the drivers not using it. * Except for rare exceptions deep in winsys code, buffers must always be allocated via pipe_buffer_create() or via screen->*buffer_create() rather than via winsys->*buffer_create().
2009-02-24gallium: Add pipe_buffer_write/read inlines.José Fonseca
Saves code, and will simplify future interface changes.
2009-02-18util: Move p_debug.h into util module.José Fonseca
The debug functions depend on several util function for os abstractions, and these depend on debug functions, so a seperate module is not possible.
2009-01-30gallium: make p_winsys internalZack Rusin
move it to pipe/internal/p_winsys_screen.h and start converting the state trackers to the screen usage
2009-01-27gallium: standardize api on the prefix "nr"Zack Rusin
2008-12-12gallium: avoid mapping same vertex buffer in subsequent framesKeith Whitwell
Quite a few util modules were maintaining a single vertex buffer over multiple frames, and potentially reusing it in subsequent frames. Unfortunately that would force us into syncrhonous rendering as the buffer manager would be forced to wait for the previous rendering to complete prior to allowing the map. This resolves that issue, but requires the state tracker to issue a few new flush() calls at the end of each frame.
2008-11-14util: Use OpenGL rasterization rules in blits and mipmap generation.Brian Paul
2008-09-04gallium: Use pipe_buffer_* inlines as much as possible.José Fonseca
2008-08-24gallium: refactor/replace p_util.h with util/u_memory.h and util/u_math.hBrian Paul
Also, rename p_tile.[ch] to u_tile.[ch]
2008-07-19gallium: Finer grained is_format_supported.José Fonseca
2008-07-03gallium: Don't forget to get overllaping blits working again.José Fonseca
2008-07-03gallium: Use surface_copy for 1:1 blits.José Fonseca
2008-06-27gallium: Drop pipe_texture->cpp and pipe_surface->cpp.José Fonseca
The chars-per-pixel concept falls apart with compressed and yuv images, where more than one pixel are coded in a single data block.

2008-05-01gallium: Notify driver of texture updates in util_blit_pixels().Michel Dänzer
2008-05-01gallium: tex surface checkpointKeith Whitwell
2008-04-29gallium: added some assertions to be sure the blit's surface formats are ↵Brian Paul
suitable
2008-04-22gallium: setup an identity viewportBrian Paul
This fixes broken blits.
2008-04-21use cso fs/vs handle functionsKeith Whitwell
2008-04-21gallium: Set all state via cso_context in blit/gen_mipmap utils.José Fonseca
cso_restore_* functions are implemented on top of cso_set_*, therefore they require full knowledge of the current pipe state to work correctly. Directly calling pipe's set_*_state functions will lead to undefined state. Also save and restore shaders.
2008-03-27gallium: return pipe_shader_state from the simple shader functionsBrian
Allows us to fix a mem leak (tokens array).
2008-03-27gallium: fix incorrect types for shadersBrian
2008-03-20gallium: set fb.width/heightBrian
2008-03-20gallium: create one vertex buffer and re-useBrian
2008-03-19gallium: explict float castsKeith Whitwell
2008-03-19gallium: implement CSO save/restore functions for use by meta operations ↵Brian
(blit, gen-mipmaps, quad-clear, etc) Also, additional cso_set_*() functions for viewport, framebuffer, blend color, etc. state.
2008-03-18gallium: new pixel blit codeBrian
Copy rectangular region from one surface to another w/ scaling. Disables most fragment operations.
