* gallium: separate out floating-point CAPs into its own enumMarek Olšák2011-11-221-6/+11
| | | | | | | | | | | | | | | The motivation behind this is to add some self-documentation in the code about how each CAP can be used. The idea is: - enum pipe_cap is only valid in get_param - enum pipe_capf is only valid in get_paramf Which CAPs are floating-point have been determined based on how everybody except svga implemented the functions. svga have been modified to match all the other drivers. Besides that, the floating-point CAPs are now prefixed with PIPE_CAPF_.

The intention was that the embedded stencil buffer would be the golden copy of the texture's stencil bits. When necessary, we scattered/gathered the stencil bits between the texture miptree and the embedded stencil buffer. This approach had a serious deficiency for mipmapped or multi-layer textures. Any given moment the embedded stencil buffer was consistent with exactly one miptree slice, the most recent one to be scattered. This permitted tests of type A to pass, but broke tests of type B. Test A: 1. Create a depthstencil texture. 2. Upload data into (level=x1,layer=y1). 3. Read and test stencil data at (level=x1, layer=y1). 4. Upload data into (level=x2,layer=y2). 5. Read and test stencil data at (level=x2, layer=y2). Test B: 1. Create a depthstencil texture. 2. Upload data into (level=x1,layer=y1). 3. Upload data into (level=x2,layer=y2). 4. Read and test stencil data at (level=x1, layer=y1). 5.

| * intel: Refactor intel_render_texture() [v2]Chad Versace2011-11-221-33/+88
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is in preparation for properly implementing glFramebufferTexture*() for mipmapped depthstencil textures. The FIXME comments deleted by this patch give a rough explanation of what was broken. This refactor does the following: - In intel_update_wrapper() and intel_wrap_texture(), change the parameters to prepare to remove functions' dependency on gl_texture_image. - Move the call to intel_renderbuffer_set_draw_offsets() from intel_render_texture() into intel_udpate_wrapper(). Each time I encounter those functions, I dislike their vague names. (Update which wrapper? What is wrapped? What is the wrapper?). So, while I was mucking around, I also renamed the functions. v2: In addition to the ``GLenum internal_format`` parameter to intel_wrap_miptree(), add a ``gl_format format`` parameter. This removes the need to recalculate for the true format from internal_format with ChooseNewTextureFormat, which was just weird. Signed-off-by: Chad Versace <[email protected]>

In the exceptional case, nr_images == 6 and depth == 1. It is simple to determine if a texture is a cube or not, so the presence of two fields here was not helpful. Worse, it was confusing. When we eventually implement GL_ARB_texture_cube_map_array, this mess would have become even more confusing. This patch removes 'nr_images' and assigns to 'depth' a consistent meaning: depth is the number of 2D slices at each miplevel. The exact semantics of depth varies according to the texture target: - For GL_TEXTURE_CUBE_MAP, depth is 6. - For GL_TEXTURE_2D_ARRAY, depth is the number of array slices. It is identical for all miplevels in the texture. - For GL_TEXTURE_3D, it is the texture's depth at each miplevel. Its value, like width and height, varies with miplevel. - For other texture types, depth is 1. As a consequence, parameters were removed from the following function signatures: intel_miptree_set_level_info Remove 'nr_images'. i945_miptree_layout brw_miptree_layout_texture brw_miptree_layout_texture_array Remove 'slices'. v2: - Replace "It's" with "Its". - Remove all hunks in intel_fbo.c. The hunks were spurious and sneaked in during a rebase. - Remove unneeded hunk in intel_tex_map_image_for_swrast(). It was a little refactor of the for-loop's upper bound. v4: In intel_miptree_get_image_offset(), document the conditions under which different if-branches are taken.

Don't map the depthstencil buffer twice Place a guard in intel_renderbuffer_map() to prevent a renderbuffer from being mapped twice. This happened if a single buffer was attached to the framebuffer's depth and stencil attachment points. (Interestingly, because intel_map_renderbuffer_gtt() is idempotent, the double mapping did not cause bugs for depthstencil buffers *without* separate stencil). 2. Stop overriding gl_framebuffer::_DepthBuffer,_StencilBuffer Normally, if a depthstencil buffer is attached to the framebuffer's depth attachment point, then _mesa_update_framebuffer() installs a wrapper depth renderbuffer at gl_framebuffer::_DepthBuffer. Ditto for the stencil attachment point and gl_framebuffer::_StencilBuffer A depthstencil intel_renderbuffer with separate stencil contains hidden depth and stencil renderbuffers, which are the *real* renderbuffers. In order to force swrast to work, we were installing, in brw_update_draw_buffer(), the hidden renderbuffers at gl_framebuffer::_DepthBuffer and _StencilBuffer, thus overriding the behavior of _mesa_update_framebuffer().

* | st/mesa: fix accum buffer allocation in st_renderbuffer_alloc_storage()Brian Paul2011-11-221-2/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the gallium driver doesn't support PIPE_FORMAT_R16G16B16A16_SNORM the call to st_choose_renderbuffer_format() would fail and we'd generate an GL_OUT_OF_MEMORY error. We'd never get to the subsequent code that handles software/malloc-based renderbuffers. Add a special-case check for PIPE_FORMAT_R16G16B16A16_SNORM which is used for software-based accum buffers. This could be fixed in other ways but it would be a much larger patch. st_renderbuffer_alloc_storage() could be reorganized in the future. This fixes accum buffer allocation for the svga driver. Note: This is a candidate for the 7.11 branch. Reviewed-by: José Fonseca <[email protected]>

* | swrast: simplify the prototype of function texture_combineYuanhan Liu2011-11-211-10/+9
| | | | | | | | | | | | | | | | | | | | | | | | Parameter n and rgbaChan are both from structure span, thus using span as paramter to simplify the prototype. Function texture_combine is only used by _swrast_texture_span, so I guess it's safe to do so. This patch is mainly for the next patch.
