| 00:22.55 | SpeedEvil | Well - if you get patches upstream - you can save billions of kilobytes. |
| 00:23.51 | SpeedEvil | It would be awesome if it was possible to give programmers an incentive to reduce power usage. |

| 01:40.15 | landley | That is, to be blunt, sad. |

| 22:16.44 | dalias | hi |
| 22:35.28 | dalias | is the arm SWP instruction atomic? |
| 22:36.13 | roxfan | supposedly |
| 22:36.19 | roxfan | it's deprecated, however |
| 22:38.17 | dalias | i'm asking from a standpoint of whether it's acceptable to use in synchronization primitives for code that's compatible with old and new arms |
| 22:38.38 | dalias | or should i just always (on linux) use the kernel assisted cmpxchg? |
| 22:39.32 | dalias | (0xffff0fc0) |
| 22:39.57 | roxfan | http://cateee.net/lkddb/web-lkddb/SWP_EMULATE.html |
| 22:40.40 | dalias | ah so it's removed on modern arms :( |
| 22:40.49 | dalias | 0xffff0fc0 it is, then |
| 22:40.51 | roxfan | well, not removed yet |
| 22:41.04 | roxfan | but might disappear in near future |
| 22:41.09 | dalias | *nod* |
| 22:41.38 | roxfan | i'd probably use conditional compilation |
| 22:43.23 | dalias | well i don't like/use swaps much anyway |
| 22:43.29 | dalias | compare-and-swap is a lot more powerful |
| 22:44.01 | dalias | and i'm a bit uncertain as to whether SWP would even be memory-synchronizing on SMP |
| 22:44.10 | dalias | (SMP with old arm is probably very unlikely anyway tho..) |
