|
| 899 | 11 |
* Remove self_configured flag to avoid unnecessary process data |
12 |
interruptions. |
|
13 |
* Replace Sysfs interface with cdev and a user space program |
|
14 |
to replace lsec; move a few sysfs attributes to proc. |

|
68 |
a cycle. |
|
69 |
* Only execute one EoE handler per EoE cycle. |
|
70 |
||
71 |
Less important issues: |
