1 | /* | ||
2 | * PowerPC atomic bit operations. | ||
3 | * | ||
4 | * Merged version by David Gibson <david@gibson.dropbear.id.au>. | ||
5 | * Based on ppc64 versions by: Dave Engebretsen, Todd Inglett, Don | ||
6 | * Reed, Pat McCarthy, Peter Bergner, Anton Blanchard. They | ||
7 | * originally took it from the ppc32 code. | ||
8 | * | ||
9 | * Within a word, bits are numbered LSB first. Lot's of places make | ||
10 | * this assumption by directly testing bits with (val & (1<<nr)). | ||
11 | * This can cause confusion for large (> 1 word) bitmaps on a | ||
12 | * big-endian system because, unlike little endian, the number of each | ||
13 | * bit depends on the word size. | ||
14 | * | ||
15 | * The bitop functions are defined to work on unsigned longs, so for a | ||
16 | * ppc64 system the bits end up numbered: | ||
17 | * |63..............0|127............64|191...........128|255...........196| | ||
18 | * and on ppc32: | ||
19 | * |31.....0|63....31|95....64|127...96|159..128|191..160|223..192|255..224| | ||
20 | * | ||
21 | * There are a few little-endian macros used mostly for filesystem | ||
22 | * bitmaps, these work on similar bit arrays layouts, but | ||
23 | * byte-oriented: | ||
24 | * |7...0|15...8|23...16|31...24|39...32|47...40|55...48|63...56| | ||
25 | * | ||
26 | * The main difference is that bit 3-5 (64b) or 3-4 (32b) in the bit | ||
27 | * number field needs to be reversed compared to the big-endian bit | ||
28 | * fields. This can be achieved by XOR with 0x38 (64b) or 0x18 (32b). | ||
