From: Jeff Garzik Date: Wed, 15 Aug 2007 09:38:46 +0000 (-0400) Subject: [libata] Remove ->irq_ack() hook, and ata_dummy_irq_on() X-Git-Tag: firefly_0821_release~26007^2~90 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=6d32d30f55020d766388df7515f771f68c973033;p=firefly-linux-kernel-4.4.55.git [libata] Remove ->irq_ack() hook, and ata_dummy_irq_on() * ->irq_ack() is redundant to what the irq handler already performs... chk-status + irq-clear. Furthermore, it is only called in one place, when screaming-irq-debugging is enabled, so we don't want to bother with a hook just for that. * ata_dummy_irq_on() is only ever used in drivers that have no callpath reaching ->irq_on(). Remove .irq_on hook from those drivers, and the now-unused ata_dummy_irq_on() Signed-off-by: Jeff Garzik --- diff --git a/drivers/ata/ahci.c b/drivers/ata/ahci.c index baf7d0562190..c888c966a020 100644 --- a/drivers/ata/ahci.c +++ b/drivers/ata/ahci.c @@ -276,8 +276,6 @@ static const struct ata_port_operations ahci_ops = { .qc_issue = ahci_qc_issue, .irq_clear = ahci_irq_clear, - .irq_on = ata_dummy_irq_on, - .irq_ack = ata_dummy_irq_ack, .scr_read = ahci_scr_read, .scr_write = ahci_scr_write, @@ -310,8 +308,6 @@ static const struct ata_port_operations ahci_vt8251_ops = { .qc_issue = ahci_qc_issue, .irq_clear = ahci_irq_clear, - .irq_on = ata_dummy_irq_on, - .irq_ack = ata_dummy_irq_ack, .scr_read = ahci_scr_read, .scr_write = ahci_scr_write, diff --git a/drivers/ata/ata_generic.c b/drivers/ata/ata_generic.c index e390ad47c8ef..6ec1bbc4fcc4 100644 --- a/drivers/ata/ata_generic.c +++ b/drivers/ata/ata_generic.c @@ -121,7 +121,6 @@ static struct ata_port_operations generic_port_ops = { .irq_handler = ata_interrupt, .irq_clear = ata_bmdma_irq_clear, .irq_on = ata_irq_on, - .irq_ack = ata_irq_ack, .port_start = ata_port_start, }; diff --git a/drivers/ata/ata_piix.c b/drivers/ata/ata_piix.c index 4b66b9e9638f..68bc0ae671c5 100644 --- a/drivers/ata/ata_piix.c +++ b/drivers/ata/ata_piix.c @@ -318,7 +318,6 @@ static const struct ata_port_operations piix_pata_ops = { .irq_handler = ata_interrupt, .irq_clear = ata_bmdma_irq_clear, .irq_on = ata_irq_on, - .irq_ack = ata_irq_ack, .port_start = ata_port_start, }; @@ -352,7 +351,6 @@ static const struct ata_port_operations ich_pata_ops = { .irq_handler = ata_interrupt, .irq_clear = ata_bmdma_irq_clear, .irq_on = ata_irq_on, - .irq_ack = ata_irq_ack, .port_start = ata_port_start, }; @@ -382,7 +380,6 @@ static const struct ata_port_operations piix_sata_ops = { .irq_handler = ata_interrupt, .irq_clear = ata_bmdma_irq_clear, .irq_on = ata_irq_on, - .irq_ack = ata_irq_ack, .port_start = ata_port_start, }; diff --git a/drivers/ata/libata-core.c b/drivers/ata/libata-core.c index 9f87f7ddd485..4f8b8d210cf4 100644 --- a/drivers/ata/libata-core.c +++ b/drivers/ata/libata-core.c @@ -5747,7 +5747,8 @@ idle_irq: #ifdef ATA_IRQ_TRAP if ((ap->stats.idle_irq % 1000) == 0) { - ap->ops->irq_ack(ap, 0); /* debug trap */ + ata_chk_status(ap); + ap->ops->irq_clear(ap); ata_port_printk(ap, KERN_WARNING, "irq trap\n"); return 1; } @@ -7137,9 +7138,6 @@ EXPORT_SYMBOL_GPL(ata_eh_qc_complete); EXPORT_SYMBOL_GPL(ata_eh_qc_retry); EXPORT_SYMBOL_GPL(ata_do_eh); EXPORT_SYMBOL_GPL(ata_irq_on); -EXPORT_SYMBOL_GPL(ata_dummy_irq_on); -EXPORT_SYMBOL_GPL(ata_irq_ack); -EXPORT_SYMBOL_GPL(ata_dummy_irq_ack); EXPORT_SYMBOL_GPL(ata_dev_try_classify); EXPORT_SYMBOL_GPL(ata_cable_40wire); diff --git a/drivers/ata/libata-sff.c b/drivers/ata/libata-sff.c index dd528dbd9ccf..ccef99a0337c 100644 --- a/drivers/ata/libata-sff.c +++ b/drivers/ata/libata-sff.c @@ -64,46 +64,6 @@ u8 ata_irq_on(struct ata_port *ap) return tmp; } -u8 ata_dummy_irq_on (struct ata_port *ap) { return 0; } - -/** - * ata_irq_ack - Acknowledge a device interrupt. - * @ap: Port on which interrupts are enabled. - * - * Wait up to 10 ms for legacy IDE device to become idle (BUSY - * or BUSY+DRQ clear).
