Re: [Qemu-devel] Re: qemu-system-sparc video problem on 16 bitdisplays

[Blue Swirl]

Digging old bugs, I found this problem.

Maybe this patch helps? I can't test it here (can't get display to 16 bit somehow).

Looks you're telling QEMU that you've got a 16 bit buffer when it's really
a 32 bit buffer.

Perhaps we're mixing up bits-per-pixel with depth?

Perhaps this in tcx.c?

   switch (ts->ds->depth) {
   case 32:
   f = tcx_draw_line32;
   break;
   case 24:
   f = tcx_draw_line24;
   break;
   default:
   case 8:
   f = tcx_draw_line8;
   break;
   case 0:
   return;
   }
