* vbo: Declare the index range invalid for DrawTransformFeedbackJason Ekstrand2016-05-231-1/+1
| | | | | | | | | | Right now, we're setting the range to [0, 0] which is obviously bogus. Instead, we should set it to be invalid like we do for DrawIndirect.

* vbo: Declare the index range invalid for DrawIndirectJason Ekstrand2016-05-231-1/+1
| | | | | | | | | | | | | | Right now, we're just setting the range to [0, MAX_UINT32] which, while correct isn't helpful. With DrawIndirect, you can't really know what the actual range is so we may as well flag it as being an invalid range. This is what we do for draws with index buffer which is similar (the indices aren't statically known) if a bit simpler.

* vbo: disable the minmax cache when the hit rate is lowNicolai Hähnle2016-02-031-2/+32
| | | | | | | | | | | | | | | | | | When applications stream their index buffers, the caches for those BOs become useless and add overhead, so we want to disable them. The tricky part is coming up with the right heuristic for *when* to disable them. The first question is which hit rate to aim for. Since I'm not aware of any interesting borderline applications that do something like "draw two or three times for each upload", I just kept it simple. The second question is how soon we should give up on the caching. Applications might have a warm-up phase where they fill a buffer gradually but then keep reusing it. For this reason, I count the number of indices that hit and miss (instead of the number of calls that hit or miss), since comparing that to the size of the buffer makes sense.

* vbo: cache/memoize the result of vbo_get_minmax_indices (v3)Nicolai Hähnle2016-02-032-0/+171
| | | | | | | | | | | | | | | | | | | | | | | | | Some games developers are unaware that an index buffer in a VBO still needs to be read by the CPU if some varying data comes from a user pointer (unless glDrawRangeElements and friends are used). This is particularly bad when they tell us that the index buffer should live in VRAM. This cache helps, e.g. lifting This War Of Mine (a particularly bad offender) from under 10fps to slightly over 20fps on a Carrizo. Note that there is nothing prohibiting a user from rendering from multiple threads simultaneously with the same index buffer, hence the locking. (The internal buffer map taken for the buffer still leads to a race, but at least the locks are a move in the right direction.) v2: disable the cache on USAGE_TEXTURE_BUFFER as well (Chris Forbes) v3: - use bool instead of GLboolean for MinMaxCacheDirty (Ian Romanick) - replace the sticky USAGE_PERSISTENT_WRITE_MAP bit by a direct AccessFlags check Reviewed-by: Chris Forbes <[email protected]> (v2) Reviewed-by: Marek Olšák <[email protected]>

| | | | | | | | | | | | | | All indirect draws are passed to the new draw function. By default there's a fallback implementation which pipes it right back to draw_prims, but eventually both the fallback and draw_prim's support for indirect drawing should be removed. This should allow a backend to properly support ARB_multi_draw_indirect and ARB_indirect_parameters.

* vbo: fix another GL_LINE_LOOP bugBrian Paul2015-11-042-2/+10
| | | | | | | | | | | | | | | | | Very long line loops which spanned 3 or more vertex buffers were not handled correctly and could result in stray lines. The piglit lineloop test draws 10000 vertices by default, and is not long enough to trigger this. Even 'lineloop -count 100000' doesn't trigger the bug. For future reference, the issue can be reproduced by changing Mesa's VBO_VERT_BUFFER_SIZE to 4096 and changing the piglit lineloop test to use glVertex2f(), draw 3 loops instead of 1, and specifying -count 1023.

| | | | | | | | | | | | | When a long GL_LINE_LOOP prim was split across primitives we drew stray lines. See previous commit for details.

* vbo: fix GL_LINE_LOOP stray line bugBrian Paul2015-10-203-3/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When long GL_LINE_LOOP primitives don't fit in one vertex buffer they have to be split across buffers. The code to do this was basically correct but drivers had to pay special attention to the _mesa_prim::begin,end flags in order to draw the sections of the line loop properly. Apparently, the only drivers to do this were those using the old 'tnl' module for software vertex processing. Now we convert the split pieces of GL_LINE_LOOP prims into GL_LINE_STRIP primitives so that drivers don't have to worry about the special begin/end flags. The only time a driver will get a GL_LINE_LOOP prim is when the whole thing fits in one vertex buffer. Mostly fixes bug 81174, but not completely. There's another bug somewhere in the src/gallium/auxiliary/draw/ code. If the piglit lineloop test is run with -count 4096, rendering is correct, but with -count 4097 there are stray lines. 4096 is a magic number in the draw code (search for "4096"). Also note that this does not fix long line loops in display lists. The next patch fixes that. v2: fix incorrect -1 in vbo_compute_max_verts(), per Charmaine. Remove incorrect assertion which was added in vbo_copy_vertices().

* vbo: reduce number of vertex buffer mappings for vertex attributesBrian Paul2015-10-201-5/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Whenever we got a glColor, glNormal, glTexCoord, etc. call outside a glBegin/End pair, we'd immediately map a vertex buffer to begin accumulating vertex data. In some cases, such as with display lists, this led to excessive vertex buffer mapping. For example, if we have a display list such as: glNewList(42, GL_COMPILE); glBegin(prim); glVertex2f(); ... glVertex2f(); glEnd(); glEndList(); Then did: glColor3f(); glCallList(42); We'd map a vertex buffer as soon as we saw glColor3f but we'd never actually write anything to it. Note that the vertex position data was put into a vertex buffer during display list compilation. With this change, we delay mapping the vertex buffer until we actually have a vertex to write to it (triggered by a glVertex() call). In the above case, we no longer map a vertex buffer when setting the color and calling the list. For drivers such as VMware's, reducing buffer mappings gives improved performance.
