* st/mesa: Remove unnecessary headers from st_framebuffer.c.Vinson Lee2010-01-141-4/+0

* mesa/st: Create front renderbuffer on the fly when supplied with a surfaceNicolai Hähnle2009-09-201-3/+15
| | | | | | | | | | | Normally, the mesa/st would create a fake front buffer out of a client-allocated surface. In the DRI setting, however, st/dri provides a front buffer surface which is created and maintained by the X server. Prefer to use this surface instead, so that front buffer rendering and reading works correctly. Signed-off-by: Nicolai Hähnle <[email protected]>

| * mesa: rework viewport/scissor initialization codeBrian Paul2009-06-171-10/+1
| | | | | | | | | | | | | | | | | | | | The first time a context is bound to a drawable, the viewport and scissor bounds are initialized to the buffer's size. This is actually a bit tricky. A new _mesa_check_init_viewport() function is called in several places to check if the viewport has been initialized. We also use a new ctx->ViewportInitialized flag instead of the overloaded ctx->FirstTimeCurrent flag.

| * mesa: Pure software accum buffer.José Fonseca2009-06-101-8/+9
| | | | | | | | | | | | | | | | | | | | 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.
* | st: if st_swapbuffers() is called for single-buffered visual don't crashBrian Paul2009-05-011-1/+19
| | | | | | | | Furthermore, return pointer(s) to the front color buffer(s).
* | st: added st_renderbuffer::defined flagBrian Paul2009-05-011-0/+12
| | | | | | | | | | | | | | | | | | | | Indicates whether there's defined image contents, or garbage/don't care. This is set when we draw into a renderbuffer and cleared when we resize/ reallocate a renderbuffer or do a buffer swap (back buffer becomes undefined). We use this to determine whether the front color buffer has been drawn to, and whether to display its contents upon glFlush/Finish(), when the new st_swapbuffers() function is used.
* | set: new st_swapbuffers() which does a true front/back buffer swapBrian Paul2009-05-011-0/+79
| | | | | | | | | | The pointers to the front/back renderbuffers are exchanged. This new function isn't actually used yet...
* | st: when double buffered, only create front color buffer on demandBrian Paul2009-05-011-8/+8
|/ | | | | Before we always created the front color buffer, even if was never used. This can save some memory.

|
* gallium: more elaborate tracking of front color buffer stateBrian Paul2008-04-091-0/+1
| | | | | | | This fixes the case where the app calls SwapBuffers then calls glReadPixels to read the front color buffer. We now keep track of when the front buffer is a _logically_ copy of the back buffer (after SwapBuffers) and read from the back color buffer instead of the front.
* gallium: accum buffer fixesBrian Paul2008-04-071-1/+1
| | | | | | | 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.
* gallium: Change pipe->flush() interface to optionally return a fence.Michel Dänzer2008-03-261-1/+2
| | | | | The cell driver still uses an internal CELL_FLUSH_WAIT flag, in the long run proper fencing should be implemented for it.

* Fix problem with initial viewport/scissor size.Brian2007-12-191-55/+54
| | | | | | | | | | | If an app never called glViewport, the viewport size was always 0 by 0 pixels. Now pass initial size to st_create_framebuffer() and initialize the viewport and scissor bounds in st_make_current(). This could also be fixed by ensuring the gl_framebuffers passed to _mesa_make_current() were initialized to the right size. But that involves allocating the renderbuffers/pipe_surfaces earlier and that runs into some other issues ATM. Also remove obsolete createRenderbuffers param to st_create_framebuffer().
* Re-org of st_create_framebuffer() and renderbuffer format selection.Brian2007-12-121-15/+16
| | | | | | | | st_create_framebuffer() now takes pipe_formats for the color, depth, stencil buffers. This avoids a round-about chain of calls to pipe->is_format_supported() for window renderbuffers (their format never changes). Renderbuffer format selection code in st_format.c is simpler now too.

* New PIPE_FLUSH_WAIT flag for pipe->flush().Brian2007-11-071-1/+1
| | | | | The state tracker doesn't have to directly call winsys->wait_idle() anymore. glFlush and glFinish both go through pipe->flush() now.
