2007-07-20libata: implement EH fast drainTejun Heo
In most cases, when EH is scheduled, all in-flight commands are aborted causing EH to kick in immediately. However, in some cases (especially with PMP), it's unclear which commands are affected by the error condition and although aborting all in-flight commands work, it isn't optimal and may cause unnecessary disruption. On the other hand, waiting for in-flight commands to drain themselves can take up to 30seconds. This patch implements EH fast drain to handle such situations. It gives in-flight commands some time to finish up but doesn't wait for too long. After EH is scheduled, fast drain timer is started and if no other completion occurs in ATA_EH_FASTDRAIN_INTERVAL all in-flight commands are aborted. If any completion occurred in the interval, the port is given another interval to finish up itself. Currently ATA_EH_FASTDRAIN_INTERVAL is 3 secs which should be enough for finishing up most commands. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-07-20libata: schedule probing after SError access failure during autopsyTejun Heo
If SError isn't accessible, EH can't tell whether hotplug has happened or not. Report SError read failure with AC_ERR_OTHER and schedule probing with hardreset. This will be mainly useful for PMPs. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-07-20libata: clear HOTPLUG flag after a resetTejun Heo
ATA_EHI_HOTPLUGGED is a hint for reset functions indicating the the port might have gone through hotplug/unplug just before entering EH. Reset functions modify their behaviors a bit to handle the situation better - e.g. using longer debouncing delay. Currently, once HOTPLUG is set, it isn't cleared till the end of EH. This is unnecessary and makes EH take longer. Clear the HOTPLUGGED flag after a reset try (successful or not). Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-07-20libata: improve SCSI scan failure handlingTejun Heo
SCSI scan may fail due to memory allocation failure even if EH is not in progress. Due to use of GFP_ATOMIC in SCSI scan path, allocation failure isn't too rare especially while probing multiple devices at once which is the case when a bunch of devices are connected to PMP. This patch moves SCSI scan failure detetion logic from ata_scsi_hotplug() to ata_scsi_scan_host() and implement synchronous scan behavior. The synchronous path sleeps briefly and repeats SCSI scan if some devices aren't attached properly. It contains robust retry loop to minimize the chance of device misdetection during boot and falls back to async retry if everything fails.

2007-07-20libata: quickly trigger SATA SPD down after debouncing failedTejun Heo
Debouncing failure is a good indicator of basic link problem. Use -EPIPE to indicate debouncing failure and make ata_eh_reset() invoke sata_down_spd_limit() if the error occurs during reset. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-07-20libata: improve SATA PHY speed down logicTejun Heo
sata_down_spd_limit() first reads the current SPD from SStatus and limit the speed to the lower one of one below the current limit or one below the current SPD in SStatus. SPD may not be accessible or valid when SPD down is requested making sata_down_spd_limit() fail when it's most needed. This patch makes the current SPD cached after each successful reset and forces GEN I speed (1.5Gbps) if neither of SStatus or the cached value is valid, so sata_down_spd_limit() is now guaranteed to lower the speed limit if lower speed is available.

2007-07-20ahci: implement SCR_NOTIFICATION r/wTejun Heo

2007-07-20ahci: make NO_NCQ handling more consistentTejun Heo
ahci_save_initial_config() is responsible for reading, screening the host CAP register and storing the modified result into hpriv->cap for the rest of the driver. Move ATA_FLAG_NO_NCQ handling into ahci_save_initial_config(). It's more consistent this way and the rest of the driver can always refer to hpriv->cap to determine configured capability.

2007-07-20libata: implement AC_ERR_NCQTejun Heo
When an NCQ command fails, all commands in flight are aborted and the offending one is reported using log page 10h. Depending on controller characteristics and LLD implementation, all commands may appear as having a device error due to shared TF status making it hard to determine what's actually going on. This patch adds AC_ERR_NCQ, marks the command reported by log page 10h with it and print extra "<F>" after the error report for the command to help distinguishing the offending command.

2007-07-20libata: improve EH report formattingTejun Heo
Requiring LLDs to format multiple error description messages properly doesn't work too well. Help LLDs a bit by making ata_ehi_push_desc() insert ", " on each invocation. __ata_ehi_push_desc() is the raw version without the automatic separator. While at it, make ehi_desc interface proper functions instead of macros. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

2007-07-20Input: appletouch - improve powersaving for Geyser3 devicesSoeren Sonnenburg
The appletouch geyser3 devices found in the Intel Macs (and possibly some later PPC ones?) send a constant stream of packets after the first touch. This results in the kernel waking up around once every couple of milliseconds to process them, making it almost impossible to spend any significant amount of time in C3 state on a dynamic HZ kernel. Sending the mode initialization code makes the device shut up until it's touched again. This patch does so after receiving 10 packets with no interesting content.
