| 291 | * RJ: The contents grab buffers needs never be accessed in the driver. |
| 292 | * Therefore there is no need to allocate them with vmalloc in order |
| 293 | * to get a contiguous virtual memory space. |
| 294 | * I don't understand why many other drivers first allocate them with |
| 295 | * vmalloc (which uses internally also get_zeroed_page, but delivers you |
| 296 | * virtual addresses) and then again have to make a lot of efforts |
| 297 | * to get the physical address. |
| 298 | * |
| 299 | * Ben Capper: |
| 300 | * On big-endian architectures (such as ppc) some extra steps |
| 301 | * are needed. When reading and writing to the stat_com array |
| 302 | * and fragment buffers, the device expects to see little- |
| 303 | * endian values. The use of cpu_to_le32() and le32_to_cpu() |
| 304 | * in this function (and one or two others in zoran_device.c) |
| 305 | * ensure that these values are always stored in little-endian |
| 306 | * form, regardless of architecture. The zr36057 does Very Bad |
| 307 | * Things on big endian architectures if the stat_com array |
| 308 | * and fragment buffers are not little-endian. |
