which path does it take? you mean...
but I get the start = reloc->lobj.gpu_offset, start is 0x182c000, this address
is gpu address,base address is 0x0. when do ttm_bo_ioremap the cpu virtual
address is 0x000000ca1182c000, reference as radeon.log ,the address mapping
seems good.
By the way, when I do the ring_ib_test on ring 5, also failed, unhandle request
address come out. Next I will do some trace for ring_ib_test,because this not
depend on libdrm.only construct msg and send.</pre>
