* mesa: check attachment Type field in renderbuffer_exists()Brian Paul2011-10-131-10/+4
| | | | | | Instead of the renderbuffer pointer. In the future, attaching a texture may not mean the renderbuffer pointer gets set too. Plus, remove some commented-out assertions.
* mesa: consolidate _mesa_source/dest_buffer_exists()Brian Paul2011-10-131-87/+43
| | | | | | v2: add a 'reading' parameter to distinguish between reading and writing to the renderbuffer (we don't want to check if _ColorReadBuffer is null when we're about to draw). Eric found this mistake.
* mesa: make _mesa_update_depth/stencil_buffer() staticBrian Paul2011-10-111-24/+10
| | | | | | | These functions were only called in framebuffer.c where they were defined. Remove the unneeded attIndex parameter too. Reviewed-by: Eric Anholt <[email protected]>

* mesa: fix up assertion in _mesa_source_buffer_existsMarek Olšák2011-03-141-0/+2
| | | | | | | | | | This was probably missed when implementing luminance and luminance alpha render targets. _mesa_get_format_bits checks for both GL_*_BITS and GL_TEXTURE_*_SIZE. This fixes: main/framebuffer.c:892: _mesa_source_buffer_exists: Assertion `....' failed.
* Revert "mesa: reduce calls to _mesa_test_framebuffer_completeness()"Brian Paul2011-03-021-1/+1
| | | | | | | This reverts commit 1f9a0a4e6e5566c36c781add5f1e62af3efdfb58. This caused trouble with Lightsmark w/ i965 driver and fbo/fbo-blit-d24s8 (see bug 34894). It's probably something simple but no time to debug now.

* mesa/965: add support for GL_EXT_framebuffer_sRGB (v2)Dave Airlie2011-02-051-0/+2
| | | | | | | | | | | | This adds i965 support for GL_EXT_framebuffer_sRGB, it introduces a new constant to say that the driver can support sRGB enabled FBOs since enabling the extension doesn't mean the driver can actually support sRGB. Also adds the suggested state flush in the core code suggested by Brian. fix the ARB_fbo color encoding. Signed-off-by: Dave Airlie <[email protected]>
* mesa: Use the common logic for "is this baseformat a color format?"Eric Anholt2011-01-031-4/+4
| | | | | | When figuring out whether a renderbuffer should be used to set the visual bits of an FBO, we were missing important baseformats like GL_RED, GL_RG, and GL_LUMINANCE.

* mesa: Identify packed depth/stencil buffers using the Format field.Nick Bowler2010-08-261-2/+2
| | | | | | | | | | | | | | | | | | | | Intel sometimes uses packed depth/stencil buffers even when only a depth buffer or only a stencil buffer was requested. Common code currently uses the _BaseFormat field to determine whether a depth/stencil wrapper is necessary. But unless the user explicitly requested a packed depth/stencil buffer, the _BaseFormat field does not encode this information, and the required wrappers are not created. The problem was introduced by commit 45e76d2665b38b ("mesa: remove a bunch of gl_renderbuffer fields"), which killed off the _ActualFormat field upon which the decision to create a wrapper used to be made. This patch changes the logic to use the Format field instead, which is more like the old code. Fixes fdo bug 27590.

* mesa: Factor out the fb initialization details from _mesa_new_framebuffer.Francisco Jerez2010-02-031-12/+29
| | | | | | | | | | | This should make things easier for drivers wanting to work with a "subclass" of gl_framebuffer. The complementary "_mesa_initialize_framebuffer" function is now called "_mesa_initialize_window_framebuffer" for the sake of symmetry. Signed-off-by: Brian Paul <[email protected]>
* mesa: Move OES_read_format support from drivers into the core.Eric Anholt2009-12-091-0/+26
| | | | | | | | | | | The assertion is that the correct read type to be using is the native type of the underlying read renderbuffer. For some fallback paths, this may be worse than GL_RGBA/GL_UNSIGNED_BYTE for reads today, but it gets all drivers the expected GL_BGRA/GL_UNSIGNED_BYTE for ARGB8888 or GL_BGR//GL_UNSIGNED_SHORT_5_6_5_REV for rgb565 with no work. This fixes the intel (and other) DRI drivers to report read formats that should hit blit PBO readpixels paths.
* mesa: remove a bunch of gl_renderbuffer fieldsBrian Paul2009-10-081-30/+40
| | | | | | _ActualFormat is replaced by Format (MESA_FORMAT_x). ColorEncoding, ComponentType, RedBits, GreenBits, BlueBits, etc. are all replaced by MESA_FORMAT_x queries.

* 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.
