283 | * | |
284 | * If a Natoma chipset is present and this is a revision 1 zr36057, | |
285 | * each MJPEG buffer needs to be physically contiguous. | |
286 | * (RJ: This statement is from Dave Perks' original driver, | |
287 | * I could never check it because I have a zr36067) | |
288 | * | |
289 | * RJ: The contents grab buffers needs never be accessed in the driver. | |
290 | * Therefore there is no need to allocate them with vmalloc in order | |
291 | * to get a contiguous virtual memory space. | |
292 | * I don't understand why many other drivers first allocate them with | |
293 | * vmalloc (which uses internally also get_zeroed_page, but delivers you | |
294 | * virtual addresses) and then again have to make a lot of efforts | |
295 | * to get the physical address. | |
296 | * | |
297 | * Ben Capper: | |
298 | * On big-endian architectures (such as ppc) some extra steps | |
299 | * are needed. When reading and writing to the stat_com array | |
300 | * and fragment buffers, the device expects to see little- | |
301 | * endian values. The use of cpu_to_le32() and le32_to_cpu() | |
302 | * in this function (and one or two others in zoran_device.c) | |
303 | * ensure that these values are always stored in little-endian | |
304 | * form, regardless of architecture. The zr36057 does Very Bad | |
305 | * Things on big endian architectures if the stat_com array | |
306 | * and fragment buffers are not little-endian. | |
