|
* If a Natoma chipset is present and this is a revision 1 zr36057,
|
| 448 |
|
|
* each MJPEG buffer needs to be physically contiguous.
|
| 449 |
|
|
* (RJ: This statement is from Dave Perks' original driver,
|
| 450 |
|
|
* I could never check it because I have a zr36067)
|
| 451 |
|
|
* The driver cares about this because it reduces the buffer
|
| 452 |
|
|
* size to MAX_KMALLOC_MEM in that case (which forces contiguous allocation).
|
| 453 |
|
|
*
|
| 454 |
|
|
* RJ: The contents grab buffers needs never be accessed in the driver.
|
| 455 |
|
|
* Therefore there is no need to allocate them with vmalloc in order
|
| 456 |
|
|
* to get a contiguous virtual memory space.
|
| 457 |
|
|
* I don't understand why many other drivers first allocate them with
|
| 458 |
|
|
* vmalloc (which uses internally also get_zeroed_page, but delivers you
|
| 459 |
|
|
* virtual addresses) and then again have to make a lot of efforts
|
| 460 |
|
|
* to get the physical address.
|
| 461 |
|
|
*
|
| 462 |
|
|
* Ben Capper:
|
| 463 |
|
|
* On big-endian architectures (such as ppc) some extra steps
|
| 464 |
|
|
* are needed. When reading and writing to the stat_com array
|
| 465 |
|
|
* and fragment buffers, the device expects to see little-
|
| 466 |
|
|
* endian values. The use of cpu_to_le32() and le32_to_cpu()
|
| 467 |
|
|
* in this function (and one or two others in zoran_device.c)
|
| 468 |
|
|
* ensure that these values are always stored in little-endian
|
| 469 |
|
|
* form, regardless of architecture. The zr36057 does Very Bad
|
| 470 |
|
|
* Things on big endian architectures if the stat_com array
|
| 471 |
|
|
* and fragment buffers are not little-endian.
