Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 305 | * If a Natoma chipset is present and this is a revision 1 zr36057, |
| 306 | * each MJPEG buffer needs to be physically contiguous. |
| 307 | * (RJ: This statement is from Dave Perks' original driver, |
| 308 | * I could never check it because I have a zr36067) |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 309 | * |
| 310 | * RJ: The contents grab buffers needs never be accessed in the driver. |
| 311 | * Therefore there is no need to allocate them with vmalloc in order |
| 312 | * to get a contiguous virtual memory space. |
| 313 | * I don't understand why many other drivers first allocate them with |
| 314 | * vmalloc (which uses internally also get_zeroed_page, but delivers you |
| 315 | * virtual addresses) and then again have to make a lot of efforts |
| 316 | * to get the physical address. |
| 317 | * |
| 318 | * Ben Capper: |
| 319 | * On big-endian architectures (such as ppc) some extra steps |
| 320 | * are needed. When reading and writing to the stat_com array |
| 321 | * and fragment buffers, the device expects to see little- |
| 322 | * endian values. The use of cpu_to_le32() and le32_to_cpu() |
| 323 | * in this function (and one or two others in zoran_device.c) |
| 324 | * ensure that these values are always stored in little-endian |
| 325 | * form, regardless of architecture. The zr36057 does Very Bad |
| 326 | * Things on big endian architectures if the stat_com array |
| 327 | * and fragment buffers are not little-endian. |
