| From | Alexander Gordeev <> | Subject | [PATCH v2 RESEND 08/23] hpsa: Fallback to MSI rather than to INTx if MSI-X failed | Date | Wed, 16 Jul 2014 20:05:12 +0200 |
| |
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.
