You could let the user enable/disable it before booting, like this: |
| 20 |
|
| 21 |
grep no_dma /proc/cmdline>/dev/null || enable_dma() |
| 22 |
|
| 23 |
or the opposite |
| 24 |
|
| 25 |
grep no_dma /proc/cmdline >/dev/null && disable_dma() |
| 26 |
|
| 27 |
Some more advanced syntax could be added too, such as no_dma=hda,hdb but |
| 28 |
that's problably overdoing it. Shouldn't there be a kernel option for |
| 29 |
this in the first place anyway? |
