* vbo: Rework checking of 'end' against _MaxElement.Kenneth Graunke2012-02-171-11/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | This failed to take basevertex into account: If basevertex < 0: (end + basevertex) might actually be in-bounds while 'end' is not. We would have clamped in this case when we probably shouldn't. This could break application drawing. If basevertex > 0: 'end' might be in-bounds while (end + basevertex) might not. We would have failed to clamp in this place. There's a comment indicating the TNL module depends on max_index being in-bounds; if so, it would likely break horribly. Rather than trying to clamp correctly in the face of basevertex, simply delete the clamping code and indicate that we don't have a valid range. This causes _tnl_vbo_draw_prims to use vbo_get_minmax_indices() to compute the actual bounds, which is much safer. NOTE: This is a candidate for release branches.

* vbo: Ignore invalid element ranges which are outside VBO bounds.Kenneth Graunke2012-02-171-0/+25
| | | | | | | | | | | | | | | | | | | | | | | Some applications, such as Regnum Online, appear to pass invalid start/end values to glDrawRangeElements. In particular, the 'start' index sometimes exceeds the maximum array element. This is clearly invalid behavior, and although the spec isn't clear, seems to result in undefined, implementation-specific behavior. This patch takes the conservative approach and simply ignores the range, while issuing a warning indicating that the application is broken and should be fixed.

* vbo: Remove pedantic warning about 'end' beind out of bounds.Kenneth Graunke2012-02-171-47/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The application supplied [start, end] range is merely a conservative hint of the ranges of index values inside the index buffer. There is no requirement that all vertices in the range [start, end] be referenced. Passing an 'end' value larger than the maximum legal index is perfectly acceptible; applications can legally pass 0xffffffff when they don't have a tighter bound readily available. Thus, the warning doesn't indicate a correctness issue; it could only indicate a performance issue. However, it does not even do that. glDrawRangeElements is designed to optimize non-VBO vertex data uploads by providing an upper bound on the size of buffers a driver would need to allocate. With VBOs, the data is already in an uploaded buffer, so the range doesn't help. The clincher is: we only know _MaxElement for VBOs. For user-space arrays, we just set it to 2,000,000,000 (see mesa/main/varray.h:63.) So we can only check this in the case where it is not useful. Many applications, including the Unigine demos, currently trigger this warning, which suggests the applications are buggy when they're actually fine. Eliminating the warning should confuse users less while not actually losing any benefit to application developers. NOTE: This is a candidate for release branches.

* intel: Fix rendering from textures after RenderTexture().Eric Anholt2012-02-175-61/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's a serious trap for drivers: RenderTexture() does not indicate that the texture is currently bound to the draw buffer, despite FinishRenderTexture() signaling that the texture is just now being unbound from the draw buffer. We were acting as if RenderTexture() *was* the start of rendering and that we could make texturing incoherent with the current contents of the renderbuffer. This caused intel oglconform sRGB Mipmap.1D_textures to fail, because we got a call to TexImage() and thus RenderTexture() on a texture bound to a framebuffer that wasn't the draw buffer, so we skipped validating the new image into the texture object used for rendering. We can't (easily) make RenderTexture() indicate the start of drawing, because both our driver and gallium are using it as the moment to set up the renderbuffer wrapper used for things like MapRenderbuffer(). Instead, postpone the setup of the workaround render target miptree until update_renderbuffer time, so that we no longer need to skip validation of miptrees used as render targets. As a bonus, this should make GL_NV_texture_barrier possible. (This also fixes a regression in the gen4 small-mipmap rendering since 3b38b33c1648b07e75dc4d8340758171e109c598, which switched set_draw_offset from image->mt to irb->mt but didn't move the irb->mt replacement up before set_draw_offset).

| | | | | | | | | | | | | | | | | | | | | | | | | Commit dc7f449d1ac53a66e6efb56ccf2a5953418a26ca introduced a new method for avoiding MOVs: try to rewrite the destination of the instruction that produced the RHS so it writes into the LHS. Unfortunately, this is not safe for swizzled texturing operations, as they return a set of four contiguous registers. Consider the following: (assign (x) (var_ref vec_ctor_x) (swiz x (tex vec4 (var_ref m_sampY) (var_ref m_cordY) 0 1 ()))) In this case, the source and destination registers are equal, since reg_offset is 0 for both. Yet, this is only a partial move: the texture operation generates four registers, and the LHS only covers one. Fixes color distortion in XBMC when using GLSL shaders.
