2009-10-05mesa/st: add ST_DEBUG environment variableKeith Whitwell
At last it's possible to turn on tgsi dumps and other debugging in the state tracker without modifying sources...
2009-10-02gallium: Preparations for adding more PIPE_TRANSFER_* usage flags.Michel Dänzer
Always test for PIPE_TRANSFER_READ/WRITE using the bit-wise and operator, and add a pipe_transfer_buffer_flags() helper for getting the buffer usage flags corresponding to them.
2009-06-10mesa: Pure software accum buffer.José Fonseca
The existing implementation was already implemented on software, but relied on the pipe driver to always support the R16G16B16A16_SNORM format. This patch eliminates that, without prejudice against a future hardware-only implementation. It also avoids some of the short <-> float conversions, and only does a read transfer of the color buffer on GL_RETURN if absolutely necessary.
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.

2009-04-15gallium: Make sure we flush before some texture / buffer operations.Thomas Hellstrom
Also implement context member functions to optimize away those flushes whenever possible. Signed-off-by: Thomas Hellstrom <thellstrom-at-vmware-dot-com>
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().
2009-02-16gallium: fix mergeKeith Whitwell
It looks like I resolved the merge conflicts but did not save my emacs buffers before committing...

2009-02-12gallium: Fix accumulation buffer tile coordinates.Michel Dänzer
2009-02-12mesa: consistantly use mesa memory-functions in gallium state trackerBrian Paul
Use _mesa_malloc(), _mesa_free(), etc everywhere, not malloc(), free(), etc. Still using CALLOC_STRUCT() at this point.
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.
2008-08-24gallium: 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]
2008-07-15st: Silence compiler warnings on Windows.Michal Krol
2008-07-13util: Eliminate pipe from the arguments to pipe_get/put_tile_xxx functions.José Fonseca
You don't need a pipe_context * for this, and all other necessary info is already inside pipe_surface.
2008-06-27mesa: Replace void * arithmetic.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.
2008-05-06gallium: create drawing surfaces as GPU_READ/WRITE onlyBrian Paul
Create different temporary surfaces for CPU_READ/WRITE when needed (such as for glReadPixels, glAccum, some glCopy/DrawPixels, glCopyTexSubImage, etc).
2008-05-01gallium: tex surface checkpointKeith Whitwell
2008-04-17gallium: add missing pipe_surface_unmap() callBrian Paul
2008-04-07gallium: slightly improved accum clear/mad operationsBrian Paul
Instead of get/put_tile(), map the buffer and operate on values directly.
2008-04-07gallium: accum buffer fixesBrian Paul
If the driver can't create a PIPE_FORMAT_R16G16B16A16_SNORM surface, create an accum surface using a shallower format and taller height. Since only the accum buffer code accesses the surface the actual format doesn't really matter, just that there's enough memory.
2008-03-26gallium: Change pipe->flush() interface to optionally return a fence.Michel Dänzer
The cell driver still uses an internal CELL_FLUSH_WAIT flag, in the long run proper fencing should be implemented for it.
2008-03-11gallium: rework CSO-related code in state trackerBrian
Use the code in cso_context.c rather than st_cache.c. Basically, binding of state objects now goes through the CSO module. But Vertex/fragment shaders go through pipe->bind_fs/vs_state() since they're not cached by the CSO module at this time. Also, update softpipe driver to handle NULL state objects in various places. This happens during context destruction. May need to update other drivers...
2008-02-15Code reorganization: update build.José Fonseca
Update the Makefiles and includes for the new paths. Note that there hasn't been no separation of the Makefiles yet, and make is jumping all over the place. That will be taken care shortly. But for now, make should work. It was tested with linux and linux-dri. Linux-cell and linux-llvm might require some minor tweaks.
2008-01-14Remove pipe->get/put_tile_rgba.Michel Dänzer
pipe_get/put_tile_rgba() now use pipe->get/put_tile internally. Also simplify the <format>_get/put_tile_rgba() helper functions and clean up some inconsitencies in them.
2008-01-14Remove mapping fields from struct pipe_surface.Michel Dänzer
It's now the responsibility of surface users to keep track of their mappings.

The _rgba versions are temporary until the state tracker is updated.
