I've been trying to track down one of the hangs on the radeon at the mo.
Tuxkart draws, amongst other things, a course map with 2 GL_LINE_LOOPS and a quad for each racer. If I either (a) remove the function to draw that from tuxkart or (b) force tcl_render_line_loop_verts to use the tcl_render_line_strip_verts path at the bottom of that function (which uses EMIT_PRIM() rather than ALLOC_ELTS et al), it doesn't hang. i.e I put "if (0 && (flags & PRIM_END)) {" at line 215 in t_dd_dmatmp2.h The only thing that looks odd is that the call to radeonEmitAOS it uses in this path is the one that's part of ALLOC_ELTS that always uses 0 as an offset, so you see the 4: value below is the same for all 3 primitives - I wondered if that was it? Here's a short extract running it in debug. basically it's flush_prims radeon_vtxfmt.c -> tcl_render_line_loop_verts -> emit_contiguous_verts (x2) ALLOC_ELTS (which does radeonEmitAOS, and AllocEltsOpenEnded) etc The hang does always trigger, sometimes it's a couple of seconds into the level, sometimes you can get 1/2-way around the track but I've played for significantly longer without a prob, with the kludge above. vtxfmt prim 0: GL_LINE_LOOP 0..95 radeonEmitAOS radeonEmitAOS: 0: 5 1: c0022f00 2: 1 3: 404 4: 453d980 radeonAllocEltsOpenEnded 95 radeonEmitState radeonAllocEltsOpenEnded: header 0xc0002a00 vfmt 0x80000008 prim 213 vtxfmt prim 1: GL_LINE_LOOP 95..190 radeonFlushElts radeonEmitAOS radeonEmitAOS: 0: 5 1: c0022f00 2: 1 3: 404 4: 453d980 radeonAllocEltsOpenEnded 95 radeonEmitState radeonAllocEltsOpenEnded: header 0xc0002a00 vfmt 0x80000008 prim 213 vtxfmt prim 2: GL_QUADS 190..206 radeonFlushElts radeonEmitAOS radeonEmitAOS: 0: 5 1: c0022f00 2: 1 3: 404 4: 453d980 radeonAllocEltsOpenEnded 24 radeonEmitState radeonAllocEltsOpenEnded: header 0xc0002a00 vfmt 0x80000008 prim 214 radeonReleaseDmaRegion from flush_prims -- Michael. _______________________________________________________________ Don't miss the 2002 Sprint PCS Application Developer's Conference August 25-28 in Las Vegas -- http://devcon.sprintpcs.com/adp/index.cfm _______________________________________________ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
