[PATCH 2/3] libata: add hp-poll support to controllers with hotplug interrutps

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This patch adds hp-poll support to the following drivers.

* ahci
* sata_nv (nf2 and c804 only)
* sata_sil
* sata_sil24

All the above controllers are capable of hotplug-by-interrupt and
hp-poll will be used only for watching disabled ports.
