From e50362eccd8809a224cda5f71714a088ba37b2ab Mon Sep 17 00:00:00 2001 From: Albert Lee Date: Tue, 27 Sep 2005 17:39:50 +0800 Subject: [PATCH] libata: interrupt driven pio for LLD libata.h: libata-core: Add ATA_FLAG_PIO_POLLING flag for LLDs that expect interrupt for command completion only. sata_nv.c: sata_vsc.c: irq handler is wrapper around ata_host_intr(), can handle PIO interrupts. sata_promise.c: sata_sx4.c: sata_qstor.c: sata_mv.c: Private irq handler. Polling mode ATA_FLAG_PIO_POLLING used for compatibility.
