* mesa: implement DEBUG_ALWAYS_FLUSH debug optionBrian Paul2012-05-112-0/+20
| | | | | | | | This flag has been around for a while but it wasn't actually used anywhere. Now, setting this flag causes a glFlush() to be issued after each drawing call (including glBegin/End, glDrawElements, glDrawArrays, glDrawPixels, glCopyPixels and glBitmap).
* mesa: fix glMaterial / dlist bugBrian Paul2012-05-113-58/+152
| | | | | | | | | | | | | When glColorMaterial() is used to latch glColor commands to a material attribute, glMaterial calls to change that material should become no-ops. This failed to work properly when the glMaterial call was inside a display list. This removes the Material function from the vbo_attrib_tmp.h template file. We have separate/different implementations for the "save" and "exec" cases now. NOTE: This is a candidate for the 8.0 branch.

* mesa: add gl_context::NewDriverState and use it for vertex arraysMarek Olšák2012-05-087-4/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The vbo module recomputes its states if _NEW_ARRAY is set, so it shouldn't use the same flag to notify the driver. Since we've run out of bits in NewState and NewState is for core Mesa anyway, we need to find another way. This patch is the first to start decoupling the state flags meant only for core Mesa and those only for drivers. The idea is to have two flag sets: - gl_context::NewState - used by core Mesa only - gl_context::NewDriverState - used by drivers only (the flags are defined by the driver and opaque to core Mesa) It makes perfect sense to use NewState|=_NEW_ARRAY to notify the vbo module that the user changed vertex arrays, and the vbo module in turn sets a driver-specific flag to notify the driver that it should update its vertex array bindings. The driver decides which bits of NewDriverState should be set and stores them in gl_context::DriverFlags. Then, Core Mesa can do this: ctx->NewDriverState |= ctx->DriverFlags.NewArray; This patch implements this behavior and adapts st/mesa. DriverFlags.NewArray is set to ST_NEW_VERTEX_ARRAYS. Core Mesa only sets NewDriverState. It's the driver's responsibility to read it whenever it wants and reset it to 0. Reviewed-by: Brian Paul <[email protected]>

* mesa,vbo: properly detect when vertex arrays need to be recalculatedMarek Olšák2012-04-193-39/+25
| | | | | | | | | | | | | | | | | | | This moves the RebindArrays flag into the vbo module, consolidates the code, and adds missing vbo_draw_method calls. Also with this change, the vertex arrays are not needlessly recalculated twice. The issue with the old code was: - If recalculate_input_bindings updates vp_varying_inputs, _NEW_ARRAY is set. - _mesa_update_state is called and the vp_varying_inputs change causes regeneration of the fixed-function shaders, which also sets _NEW_PROGRAM. - The occurence of either _NEW_ARRAY or _NEW_PROGRAM sets the recalculate_inputs flag to TRUE again. - The new code sets the flag to FALSE after the second _mesa_update_state, because there can't possibly be any change which would require recalculating the arrays.

| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | 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 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is necessary because i965 will need to call vbo_bind_array() when cleaning up after a buffer resolve meta-op. Detailed Explanation -------------------- The vbo module tracks vertex attributes separately from the gl_context. Specifically, the vbo module maintins vertex attributes in vbo_exec_context::array::inputs, which is synchronized with gl_context::Array::ArrayObj::VertexAttrib by vbo_bind_array(). vbo_draw_arrays() calls vbo_bind_array() to perform the synchronization before calling the real draw call, vbo_context::draw_arrays. Intel hardware accomplishes buffer resolves with a meta-op. Frequently, that meta-op must be performed within glDraw* in the moment immediately before the draw occurs (The hardware designers hate us...). After performing the meta-op, but before calling vbo_bind_array(), the gl_context's vertex attributes will have been restored to their original state (that is, their state before the meta-op began), but the vbo module's vertex attribute are those used in the last meta-op. Therefore we must manually synchronize the two with vbo_bind_array() before continuing with the original draw command (that is, the one requested with glDraw*).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This hook allows the driver to prepare for a glBegin/glEnd. i965 will use the hook to avoid avoid recursive calls to FLUSH_VERTICES during a buffer resolve meta-op. Detailed Justification ---------------------- When vertices are queued during a glBegin/glEnd block, those vertices must of course be drawn before any rendering state changes. To enusure this, Mesa calls FLUSH_VERTICES as a prehook to such state changes. Therefore, FLUSH_VERTICES itself cannot change rendering state without falling into a recursive trap. This precludes meta-ops, namely i965 buffer resolves, from occuring while any vertices are queued. To avoid that situation, i965 must satisfy the following condition: that it queues no vertex if a buffer needs resolving. To satisfy this, i965 will use the PrepareExecBegin hook to resolve all buffers on entering a glBegin/glEnd block. -------- v2: Don't add dd_function_table::CleanupExecEnd.

The commit was broken, and ended up returning false all the time because nobody in the world binds every single possible vertex array. On further reflection, we don't want to discount stride == 0: This function is just used for deciding to calculate whether to compute the bonuds on the index, and there's no sense in computing index bounds when stride == 0. For the separate question of "how much data do I upload for this vertex element?", the i965 driver was fixed to upload the data.
