[PATCH 0/2] ata: Introduce the AHCI_HFLAG_EDGE_IRQ_BROKEN in libahci and enabling it for ahci_xgene driver.

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

 



This patch set implements a workaround for an errate in the APM
X-Gene SATA host controller with edge interrupt. The HOST_IRQ_STAT
misses the edge interrupt from the PORT_IRQ_STAT when clearing the
HOST_IRQ_STAT and reporting the PORT_IRQ_STAT happens in same clock
cycle.
