* mesa: refactor: move _mesa_resizebuffers(), _mesa_ResizeBuffersMESA() to ↵Brian Paul2008-09-211-0/+78
| | | | | | framebuffer.c (cherry picked from commit 9091015a9782ad15e58540a8fd61df83ea2bfe31)
* fix BUFFER_DEPTH/BUFFER_ACCUM mix-upBrian Paul2008-09-021-6/+6
|
* Fix some issues with glDrawBuffer(GL_NONE), bug 14198Brian2008-01-221-0/+3
| | | | | Set _ColorDrawBuffers[0] = NULL if no renderbuffers enabled. Check that _ColorDrawBuffers[0] is non-null before dereferencing in a few places.
* Replace gl_framebuffer's _ColorDrawBufferMask with _ColorDrawBufferIndexesBrian2008-01-061-32/+13
| | | | | | | Each array element is now a BUFFER_x token rather than a BUFFER_BIT_x bitmask. The number of active color buffers is specified by _NumColorDrawBuffers. This builds on the previous DrawBuffer changes and will help with drivers implementing GL_ARB_draw_buffers.
* Simplify ctx->_NumColorDrawBuffers, _ColorDrawBuffers and fix bug 13835.Brian2008-01-061-26/+71
| | | | | | | | | | | These fields are no longer indexed by shader output. Now, we just have a simple array of renderbuffer pointers. If the shader writes to gl_FragData[i], send those colors to the N _ColorDrawBuffers. Otherwise, replicate the single gl_FragColor (or the fixed-function color) to the N _ColorDrawBuffers. A few more changes and simplifications can follow from this...
* Rework the GL_READ_BUFFER, GL_DRAW_BUFFER state repairs that Roland ↵Brian2007-08-161-6/+20
| | | | | | | | | previously did. Basically, in update_framebuffer() (which should be called after an FBO is bound with MakeCurrent or BindFramebuffer) we check if the FBO is a window-system FBO. If it is, update the FBO's GL_READ/DRAW_BUFFER state according to the context state. Old code still in place but disabled with #if 0 / #endif.
* update comments, etc related to Read/DrawBuffer stateBrian2007-08-161-18/+28

* Implement mutex/locking around texture object reference counting.Brian2007-08-131-9/+4
| | | | | | Use new _mesa_reference_texobj() function for referencing/unreferencing textures. Add new assertions/tests to try to detect invalid usage of deleted textures.
* fix mesa's handling of fbo's / window fb (again)Roland Scheidegger2007-07-191-2/+1
| | | | | | | | Make sure the relevant fields in window fbs get updated at appropriate time (those are NOT the same as fbos!!!), and fix up related code accordingly. This is a bit ugly, but there's a reason the issues section in EXT_fbo is a couple hundred pages long... Hopefully correct now.
* fix up mesa's probably bogus framebuffer updates with different read/write fbsRoland Scheidegger2007-07-191-12/+26
| | | | | | Conflicts: src/mesa/main/framebuffer.c
* Minor clean-up of polygon offset logic. Properly compute _MRD field.Brian2007-07-111-1/+3
|
* Fix some renderbuffer reference counting issues. Also fixes a mem leak.Brian2007-03-251-44/+8
|
* Assorted fixes for dealing with zero-size frame/renderbuffers.Brian2007-03-161-2/+5
| | | | | | | | | | In xmesa_check_and_update_buffer_size() handle xmctx==NULL correctly: still call _mesa_resize_framebufer(). If we don't we can wind up in a situation where the framebuffer size is non-zero but an attached renderbuffer size is still initialized to zero. This inconsistancy can later cause problems. Check for zero-size renderbuffers in update_color_draw_buffers() and update_color_read_buffer(). See bug 7205.
* unreference old framebuffer, if needed, in _mesa_reference_framebuffer()Brian2007-03-061-0/+7
|
* Fix/improve framebuffer object reference counting.Brian2007-03-061-14/+32
| | | | | | | Use _mesa_reference_framebuffer() and _mesa_unreference_framebuffer() functions to be sure reference counting is done correctly. Additional assertions are done too. Note _mesa_dereference_framebuffer() renamed to "unreference" as that's more accurate.
* Take care of texObj reference in _mesa_free_framebuffer_data()Brian2007-03-061-6/+11
|
* assert that fb->RefCount==0 in _mesa_free_framebuffer_data()Brian2007-02-271-0/+1
|
* Do proper framebuffer refcounting in _mesa_make_current().Brian2007-02-261-16/+23
| | | | | | Also, added DeletePending field to gl_framebuffer used when a window has been deleted, but there still may be rendering contexts attached to the gl_framebuffer object.
* Set _NEW_BUFFERS in _mesa_resize_framebuffer(). This makes sure the swrastBrian Paul2006-10-161-2/+7
| | | | | module updates its state (CLIP_BIT) upon resizes. The driver could do this instead, but doing it here is safer.

|
* Support for combined depth/stencil renderbuffers (GL_EXT_packed_depth_stencil).Brian Paul2005-11-161-2/+103
| | | | | depthstencil.c provides wrappers for treating depth/stencil buffers either as regular depth or stencil renderbuffers.
