[PATCH v1 0/2] ata: Fixes related to edge trigger latch 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. It also implements the capability to override generic interrupt
handler.

v1 change:
* Implement the capability for LDD to override interrupt handler.

* ahci_xgene driver implements the edge trigger interrupt handler.

Suman Tripathi (2):
  libahci: Implement the capability to override the generic ahci
    interrupt handler
  ahci_xgene: Implement the workaround to fix the missing of edge
    interrupt for HOST_IRQ_STAT
