IIRC, at least on mach64, hardware cursor position updates don't go through the draw engine FIFO (any registers below dword offset 0x040 don't use the FIFO), so locking isn't necessary. However, we do lock the DRM when updating the cursor image, since it blits the image to the framebuffer through the host data FIFO. When I was first working on 2D/3D sync, we did the sync on every EnterServer, which slowed things down considerably since the sync happened on every cursor position update. Now we only do the sync for blits and XAA operations and I've never seen a lockup because of the hardware cursor. > Anyway, Alan, can you try if disabling Silken mouse or even using SW > cursor (make sure you have the fix for crashes with SW cursor and DRI > though :) makes a difference? > > > The 3D app is burning a lot of CPU and the system is otherwise running. > > At the point the 3D is killed (kill -9 etc) the box hangs solid > > Classical chip crash or lockup. :\ > > > -- Leif Delgass http://www.retinalburn.net ------------------------------------------------------- This SF.net email is sponsored by: SlickEdit Inc.
