438 | * else we allocate the memory in framgents with get_zeroed_page. | |
439 | * | |
440 | * If a Natoma chipset is present and this is a revision 1 zr36057, | |
441 | * each MJPEG buffer needs to be physically contiguous. | |
442 | * (RJ: This statement is from Dave Perks' original driver, | |
443 | * I could never check it because I have a zr36067) | |
444 | * The driver cares about this because it reduces the buffer | |
445 | * size to MAX_KMALLOC_MEM in that case (which forces contiguous allocation). | |
446 | * | |
447 | * RJ: The contents grab buffers needs never be accessed in the driver. | |
448 | * Therefore there is no need to allocate them with vmalloc in order | |
449 | * to get a contiguous virtual memory space. | |
450 | * I don't understand why many other drivers first allocate them with | |
451 | * vmalloc (which uses internally also get_zeroed_page, but delivers you | |
452 | * virtual addresses) and then again have to make a lot of efforts | |
453 | * to get the physical address. | |
454 | * | |
455 | * Ben Capper: | |
456 | * On big-endian architectures (such as ppc) some extra steps | |
457 | * are needed. When reading and writing to the stat_com array | |
458 | * and fragment buffers, the device expects to see little- | |
459 | * endian values. The use of cpu_to_le32() and le32_to_cpu() | |
460 | * in this function (and one or two others in zoran_device.c) | |
461 | * ensure that these values are always stored in little-endian | |
462 | * form, regardless of architecture. The zr36057 does Very Bad | |
463 | * Things on big endian architectures if the stat_com array | |
464 | * and fragment buffers are not little-endian. | |
