* vbo: convert display list GL_LINE_LOOP prims to GL_LINE_STRIPBrian Paul2015-10-201-0/+53
| | | | | | | | | | | | | When a long GL_LINE_LOOP prim was split across primitives we drew stray lines. See previous commit for details. This patch converts GL_LINE_LOOP prims into GL_LINE_STRIP prims so that drivers don't have to worry about the _mesa_prim::begin/end flags.

* 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.

* mesa: use fi_type in vertex attribute codeMarius Predut2015-02-259-80/+97
| | | | | | | | | | | | | | | | | | | | | | | For 32-bit builds, floating point operations use x86 FPU registers, not SSE registers. If we're actually storing an integer in a float variable, the value might get modified when written to memory. This patch changes the VBO code to use the fi_type (float/int union) to store/copy vertex attributes. Also, this can improve performance on x86 because moving floats with integer registers instead of FP registers is faster. Neil Roberts review: - include changes on all places that are storing attribute values. - check with and without -O3 compiler flag.

* mesa: fix display list 8-byte alignment issueBrian Paul2015-01-301-1/+4
| | | | | | | | | | | | | | | | | | | | | The _mesa_dlist_alloc() function is only guaranteed to return a pointer with 4-byte alignment. On 64-bit systems which don't support unaligned loads (e.g. SPARC or MIPS) this could lead to a bus error in the VBO code. The solution is to add a new _mesa_dlist_alloc_aligned() function which will return a pointer to an 8-byte aligned address on 64-bit systems. This is accomplished by inserting a 4-byte NOP instruction in the display list when needed. The only place this actually matters is the VBO code where we need to allocate a 'struct vbo_save_vertex_list' which needs to be 8-byte aligned (just as if it were malloc'd). The gears demo and others hit this bug. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=88662 Cc: "10.4" <[email protected]> Reviewed-by: José Fonseca <[email protected]>
