| wpwrak | they missed the obvious solution: draw it in n-space, then project on 2D space | 14:01 |
| xiangfu | wpwrak, I got your email. I am waiting the package now. then try to look into your source code. | 14:03 |
| wpwrak | you'll like it - it's a big mess :) | 14:05 |
| xiangfu | I like swimming in your source code. :-) | 14:08 |

| mth | larsc (or anyone else): I'm a bit confused by ioremap_nocache: is it ever desirable to have an I/O range mapped *with* cache? | 16:09 |
| larsc | maybe ;) | 16:10 |
| larsc | e.g. if the memory is non volatile | 16:11 |
| larsc | on mips ioremap and ioremap_nocache behave the same, but here is also ioremap_chached | 16:11 |
| mth | ah | 16:12 |
| mth | the i2s driver driver uses ioremap_nocache, while most other drivers just just ioremap | 16:12 |
| mth | but they're actually doing the same thing then? | 16:12 |
| larsc | yes | 16:12 |
| larsc | ioremap is older | 16:12 |
| larsc | at somepoint ioremap_nocache and ioremap_cached were introduced | 16:12 |
| mth | for the JZ4770 drivers I'm trying to use the devm_* functions as much as possible, since it really simplifies the probe/remove operations | 16:13 |
| mth | but there is no devm_request_and_ioremap_uncached, just devm_request_and_ioremap | 16:13 |
| larsc | that one internally uses the noncached version by default | 16:14 |
| larsc | and falls back to cachable if the ioresource has a CACHABLE flag set | 16:15 |
| larsc | iirc | 16:15 |
| mth | currently the remapping is just for show anyway, the Ingenic code just pokes using direct pointers without using writeb etc ;) | 16:18 |
| mth | but it will at least log something if two driver try to claim the same address range | 16:18 |
| larsc | yes | 16:18 |
