This patch converts the trigger for the LED at the front of Apple's iBooks to libata. It's merely a replacement of the string ide by disk.
The patch is taken from http://dev.gentoo.org/~josejx/ata.patch. I've asked Joseph Jezak if he intends to send this patch upstream, but as he did not reply I'll do so. --- arch/powerpc/configs/pmac32_defconfig | 2 +- arch/powerpc/configs/ppc6xx_defconfig | 2 +- drivers/ata/libata-core.c | 4 ++ drivers/ide/ide-disk.c | 2 +- drivers/leds/Kconfig | 10 +++--- drivers/leds/Makefile | 2 +- drivers/leds/ledtrig-disk.c | 64 +++++++++++++++++++++++++++++++++ drivers/leds/ledtrig-ide-disk.c | 64 --------------------------------- drivers/macintosh/Kconfig | 11 +++--- drivers/macintosh/via-pmu-led.c | 4 +- include/linux/leds.h | 6 ++-- 11 files changed, 87 insertions(+), 84 deletions(-) create mode 100644 drivers/leds/ledtrig-disk.c delete mode 100644 drivers/leds/ledtrig-ide-disk.c diff --git a/arch/powerpc/configs/pmac32_defconfig b/arch/powerpc/configs/pmac32_defconfig index f8b394a..cff5d4e 100644 --- a/arch/powerpc/configs/pmac32_defconfig +++ b/arch/powerpc/configs/pmac32_defconfig @@ -180,7 +180,7 @@ CONFIG_ADB=y CONFIG_ADB_CUDA=y CONFIG_ADB_PMU=y CONFIG_ADB_PMU_LED=y -CONFIG_ADB_PMU_LED_IDE=y +CONFIG_ADB_PMU_LED_DISK=y CONFIG_PMAC_APM_EMU=m CONFIG_PMAC_MEDIABAY=y CONFIG_PMAC_BACKLIGHT=y diff --git a/arch/powerpc/configs/ppc6xx_defconfig b/arch/powerpc/configs/ppc6xx_defconfig index 04360f9..c56464d 100644 --- a/arch/powerpc/configs/ppc6xx_defconfig +++ b/arch/powerpc/configs/ppc6xx_defconfig @@ -471,7 +471,7 @@ CONFIG_ADB=y CONFIG_ADB_CUDA=y CONFIG_ADB_PMU=y CONFIG_ADB_PMU_LED=y -CONFIG_ADB_PMU_LED_IDE=y +CONFIG_ADB_PMU_LED_DISK=y CONFIG_PMAC_APM_EMU=y CONFIG_PMAC_MEDIABAY=y CONFIG_PMAC_BACKLIGHT=y diff --git a/drivers/ata/libata-core.c b/drivers/ata/libata-core.c index 4a3a5ae..d37e3a2 100644 --- a/drivers/ata/libata-core.c +++ b/drivers/ata/libata-core.c @@ -66,6 +66,7 @@ #include <asm/byteorder.h> #include <linux/cdrom.h> #include <linux/ratelimit.h> +#include <linux/leds.h> #include "libata.h" #include "libata-transport.h" @@ -4823,6 +4824,9 @@ void ata_qc_complete(struct ata_queued_cmd *qc) { struct ata_port *ap = qc->ap; + /* Trigger the LED (if available) */ + ledtrig_disk_activity(); + /* XXX: New EH and old EH use different mechanisms to * synchronize EH with regular execution path. * diff --git a/drivers/ide/ide-disk.c b/drivers/ide/ide-disk.c index 2747980..cb25bd6 100644 --- a/drivers/ide/ide-disk.c +++ b/drivers/ide/ide-disk.c @@ -186,7 +186,7 @@ static ide_startstop_t ide_do_rw_disk(ide_drive_t *drive, struct request *rq, BUG_ON(drive->dev_flags & IDE_DFLAG_BLOCKED); BUG_ON(rq->cmd_type != REQ_TYPE_FS); - ledtrig_ide_activity(); + ledtrig_disk_activity(); pr_debug("%s: %sing: block=%llu, sectors=%u, buffer=0x%08lx\n", drive->name, rq_data_dir(rq) == READ ?
