I'm trying to make a mapping (with burst mode (CCA4)) from the graphic card
memory to the virtual memory space.
I used the __ioremap with different parameters without success.
The grafic card memory is 64MB, and can be found at 0x00800000 and should be
mapped to a memory space that can be accessed via a kernel module or via user
I tried the following mapping:
add_wired_entry((0x00800000 >> 2) | 0x0027, (0x00900000 >> 2) | 0x0027,
0x30000000 | 0x0027, 0x01ffe000);
add_wired_entry((0x00a00000 >> 2) | 0x0027, (0x00a00000 >> 2) | 0x0027,
0x32000000 | 0x0027, 0x01ffe000);
This doesn't work either.
Does anybody have an idea how to make the CCA4 mapping?
