Yes, I transplant the radeon_driver from 64bit_kernel to a mini 32bit_os. The
purpose is to open radeon_benchmark or Xorg in the mini_32bit_os.
So, I think ring_test success means GPU work correctly and smmothly.
But ,my ring_test in the mini_32bit_os does not success. When I read scratch

Thanks for you reply!
I use PCI??MMIO to access VRAM and GTT areas. And for ring_buffer, it alloced
from the vmalloc?area and vmap to the physical address using page table.
If enable the radeon_benchmark, it first to prepare the dma channel.
"set_tex_resource(), set_render_target(), cp_set_
palace,
ring_test will not work?

HI,all
Now, my lab is using radeon_ati card?And, I need ati_card dma
function?But, I do not clear that how the ati card know the dma address which
alloced by kernel??
Can any kernel drivers for radeon card give me some advise or explain the
answer?
I have read the radeon dr
