2010-03-13st/mesa: Validate the state in st_readpixels.Chia-I Wu
The front renderbuffer of a framebuffer is usually added as needed when glReadBuffer(GL_FRONT) is called. When the call is followed by glReadPixels, we should validate the state before reading from the renderbuffer.
2010-03-11gallium: remove pipe_context member from pipe_transferKeith Whitwell
There was very little use for this beyond permitting the pipe_context::tex_transfer_destroy() function to omit the pipe_context argument. This change adds the pipe_context argument into tex_transfer_destroy() so that it looks like other pipe_context functions, and removes the pipe_context pointer from pipe_transfer.

This patch removes nblocksx, nblocksy arrays from pipe_texture (can be recalculated if needed).

2009-04-17gallium: Create OGL state tracker wrappers for various CPU access operations.Thomas Hellstrom
There are two usage types of buffer CPU accesses: One where we try to use the buffer contents for multiple draw commands in a batch. (batch := sequence of commands that are flushed together), like incrementally adding bitmaps to a bitmap texture that is reallocated on flush. And one where we assume we can safely overwrite the old buffer contexts, like glTexSubImage. In this case we need to make sure all old drawing commands referencing the buffer are flushed before we map the buffer. This is easily forgotten. Add wrappers for the most common of these operations. The first type is prefixed with "st_no_flush" and the second type is prefixed with "st_cond_flush", where "cond" indicates that we attmpt to only flush if there is indeed unflushed draw commands referencing the buffer. Prefixed functions are screen::get_tex_transfer pipe_buffer_write pipe_buffer_read pipe_buffer_map Please use the wrappers whenever possible.

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().

2009-02-05gallium: No longer allow CPU mapping surfaces directly.Michel Dänzer
Instead, a new pipe_transfer object has to be created and mapped for transferring data between the CPU and a texture. This gives the driver more flexibility for textures in address spaces that aren't CPU accessible. This is a first pass; softpipe/xlib builds and runs glxgears, but it only shows a black window. Looks like something's off related to the Z buffer, so the depth test always fails.
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.

2008-05-07gallium: fix some render to texture bugsBrian Paul
Before, we were sometimes rendering into a stale texture because st_finalize_texture() would discard the old texture and create a new one. Moved st_update_framebuffer atom after texture validation so that we can create a new renderbuffer surface if the texture changes. Also, split texture validation into two parts: finalize_textures and update_textures. Do finalize_textures first to avoid getting into the situtation where we're doing a pipe->surface_copy() mid-way through state validation. Some debug code still in place, but disabled...
