[PATCH v2 RESEND 08/23] hpsa: Fallback to MSI rather than to INTx if MSI-X failed

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

 



Currently the driver falls back to INTx mode when MSI-X
initialization failed. This is a suboptimal behaviour
for chips that also support MSI. This update changes that
behaviour and falls back to MSI mode in case MSI-X mode
initialization failed.
