* [PATCH] libata: add missing ->data_xfer for pdc_admaTejun Heo2006-06-11
| | | | | | | | | | | | | | | pdc_adma use libata-core PIO path but were left out during ->data_xfer conversion. Initialize with proper callbacks. This patch is against the current libata-dev#ALL. Controllers which implement their own PIO HSM (ahci and sil24) don't need ->data_xfer, so the above two are the only drivers which were left out during conversion. From: "Barry K.

* [PATCH] sata_sil24: convert to new probing mechanism and add hotplug supportTejun Heo2006-05-31
| | | | | | | | | | | Convert to new probing mechanism and add hotplug support by enabling PORT_IRQ_PHYRDY_CHG, marking ehi for hotplug and scheduling EH on PORT_IRQ_PHYRDY_CHG or PORT_IRQ_DEV_XCHG. Sil3124/32 family of controllers don't have any mechanism to wait for the first D2H FIS after hotplug, so ATA_FLAG_SKIP_D2H_BSY is used. Signed-off-by: Tejun Heo <htejun@gmail.com>
* [PATCH] ahci: convert to new probing mechanism and add hotplug supportTejun Heo2006-05-31
| | | | | | | | | | | | | | | | | Convert to new probing mechanism and add hotplug support by enabling PORT_IRQ_PHYRDY, marking ehi for hotplug and scheduling EH on CONNECT/PHYRDY interrupts. Unfortunately, ahci cannot reliably wait for the first D2H FIS after hotplug. It sometimes succeeds but times out more often than not, so ATA_FLAG_SKIP_D2H_BSY is used. This patch also fixes ahci_hardreset() such that D2H Register FIS RX area is cleared before issuing COMRESET. Without this, ata_busy_sleep() after COMRESET might prematually finish if the previous TF contains DRDY && !BSY. Signed-off-by: Tejun Heo <htejun@gmail.com>
* [PATCH] sata_sil: convert to new probing mechanism and add hotplug supportTejun Heo2006-05-31
| | | | | | | | | | | | | | Convert to new probing mechanism and add hotplug support by enabling SATA IRQ for SError.N, marking ehi for hotplug and scheduling EH on SATA IRQs. Sil3112/3512/3114 family of controllers use COMRESET as TF clearing point and can reliably wait for D2H FIS after COMRESET whether the FIS is the first D2H FIS after POR or in response to the COMRESET. Thus, setting ATA_FLAG_HRST_TO_RESUME is enough for device detection after hotplug. Signed-off-by: Tejun Heo <htejun@gmail.com>

* [PATCH] libata-hp: update unload-unplugTejun Heo2006-05-31
| | | | | | | | | Update unload unplug - driver unloading / PCI removal. This is done by ata_port_detach() which short-circuits EH, disables all devices and freezes the port. With this patch, EH and unloading/unplugging are properly synchronized. Signed-off-by: Tejun Heo <htejun@gmail.com>
* [PATCH] libata-hp: implement bootplugTejun Heo2006-05-31
| | | | | | | | | | | | Implement bootplug - boot probing via hotplug path. While loading, ata_host_add() simply schedules probing and invokes EH. After EH completes, ata_host_add() scans and assicates them with SCSI devices. EH path is slightly modified to handle this (e.g. no autopsy during bootplug). The SCSI part is left in ata_host_add() because it's shared with legacy path and to keep probing order as before (ATA scan all ports in host_set then attach all).

* [PATCH] libata-hp: implement SCSI part of hotplugTejun Heo2006-05-31
| | | | | | | | | | | Implement SCSI part of hotplug. This must be done in a separate context as SCSI makes use of EH during probing. SCSI scan fails silently if EH is in progress. In such cases, libata pauses briefly and retries until every device is attached. Signed-off-by: Tejun Heo <htejun@gmail.com>
* [PATCH] libata-hp: implement hotplugTejun Heo2006-05-31
| | | | | | | | | | | | | | | Implement ATA part of hotplug. To avoid probing broken devices over and over again, disabled devices are not automatically detached. They are detached only if probing is requested for the device or the associated port is offline. Also, to avoid infinite probing loop, Each device is probed only once per EH run. As SATA PHY status is fragile, devices are detached only after it has used up its recovery chances unless explicitly requested by LLDD or user (LLDD may request direct detach if, for example, it supports cold presence detection).

* [PATCH] libata-hp: implement ata_eh_detach_dev()Tejun Heo2006-05-31
| | | | | | | | | Implement ata_eh_detach_dev(). This function is responsible for detaching an ATA device and offlining the associated SCSI device atomically so that the detached device is not accessed after ATA detach is complete. Signed-off-by: Tejun Heo <htejun@gmail.com>
* [PATCH] sata_sil24: update sil24_hardreset()Tejun Heo2006-05-31
| | | | | | | | | | | Use phy debouncing instead of unconditional wait after DEV_RST and make sil24_hardreset() to request followup SRST as that's the only way to wait for !BSY. Note that the original implementation never worked - if the cached status was !BSY, ata_busy_sleep() finished immediately; otherwise, it timed out regardless of the actual device status.

* [PATCH] sata_sil: new interrupt handlerTejun Heo2006-05-31
| | | | | | | | | | | | | | | The DMA complete bit of these controllers reflects ATA IRQ status while no DMA command is in progress. So, we can tell whether the controller is raising an interrupt or not in deterministic manner. This patch gives sata_sil its own interrupt handler which behaves much better than the original one in terms of error detection and handling. This change is also necessary for later hotplug support. Further improvements are possible, in both 2 and 4 ports versions, we can get all status with only one readl and using custom bmdma operations can further cut down register accesses.

* [PATCH] libata-hp-prep: implement followup softreset handlingTejun Heo2006-05-31
| | | | | | | | | | | | | | | In some cases, hardreset must be followed by SRST. * some controllers can't classify with hardreset * some controllers can't wait for !BSY after hardreset (LLDD should explicitly request followup softreset by returning -EAGAIN) * (later) PM needs SRST w/ PMP==15 to operate after hardreset To handle above cases, this patch implements follow-up softreset. After a hardreset, ata_eh_reset() checks whether any of above conditions are met and do a follow-up softreset if necessary. Signed-off-by: Tejun Heo <htejun@gmail.com>
* [PATCH] libata-hp-prep: add prereset() method and implement ata_std_prereset()Tejun Heo2006-05-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With hotplug, every reset might be a probing reset and thus something similar to probe_init() is needed. prereset() method is called before a series of resets to a port and is the counterpart of postreset(). prereset() can tell EH to use different type of reset or skip reset by modifying ehc->i.action. This patch also implements ata_std_prereset(). Most controllers should be able to use this function directly or with some wrapping. After hotplug, different controllers need different actions to resume the PHY and detect the newly attached device. Controllers can be categorized as follows. * Controllers which can wait for the first D2H FIS after hotplug. Note that if the waiting is implemented by polling TF status, there needs to be a way to set BSY on PHY status change. It can be implemented by hardware or with the help of the driver. * Controllers which can wait for the first D2H FIS after sending COMRESET. These controllers need to issue COMRESET to wait for the first FIS. Note that the received D2H FIS could be the first D2H FIS after POR (power-on-reset) or D2H FIS in response to the COMRESET. Some controllers use COMRESET as TF status synchronization point and clear TF automatically (sata_sil). * Controllers which cannot wait for the first D2H FIS reliably. Blindly issuing SRST to spinning-up device often results in command issue failure or timeout, causing extended delay. For these controllers, ata_std_prereset() explicitly waits ATA_SPINUP_WAIT (currently 8s) to give newly attached device time to spin up, then issues reset. Note that failing to getting ready in ATA_SPINUP_WAIT is not critical. libata will retry. So, the timeout needs to be long enough to spin up most devices. LLDDs can tell ata_std_prereset() which of above action is needed with ATA_FLAG_HRST_TO_RESUME and ATA_FLAG_SKIP_D2H_BSY flags. These flags are PHY-specific property and will be moved to ata_link later. While at it, this patch unifies function typedef's such that they all have named arguments.

* [PATCH] libata-hp-prep: implement sata_phy_debounce()Tejun Heo2006-05-31
| | | | | | | | | | | | | | | With hotplug, PHY always needs to be debounced before a reset as any reset might find new devices. Extract PHY waiting code from sata_phy_resume() and extend it to include SStatus debouncing. Note that sata_phy_debounce() is superset of what used to be done inside sata_phy_resume(). Three default debounce timing parameters are defined to be used by hot/boot plug. As resume failure during probing will be properly handled as errors, timeout doesn't have to be long as before. probeinit() uses the same timeout to retain the original behavior.

* [PATCH] libata-hp-prep: add ata_aux_wqTejun Heo2006-05-31
| | | | | | | | It's best to run ATA hotplug from EH but attaching SCSI devices needs working EH. ata_aux_wq is used to give SCSI hotplug operations a separate context. Signed-off-by: Tejun Heo <htejun@gmail.com>
* [PATCH] libata-hp-prep: store attached SCSI deviceTejun Heo2006-05-31
| | | | | | | | | | | | | Add device persistent field dev->sdev and store the attached SCSI device. With hotplug, libata needs to know the attached SCSI device to offline and detach it, but scsi_device_lookup() cannot be used because libata will reuse SCSI ID numbers - dead but not gone devices (due to zombie opens, etc...) interfere with the lookup. dev->sdev doesn't hold reference to the SCSI device. It's cleared when the SCSI device goes away. Signed-off-by: Tejun Heo <htejun@gmail.com>
* [PATCH] libata-hp-prep: implement ap->hw_sata_spd_limitTejun Heo2006-05-31
| | | | | | | | | Add ap->hw_sata_spd_limit and initialize it once during the boot initialization (or driver load initialization). ap->sata_spd_limit is reset to ap->hw_sata_spd_limit on hotplug. This prevents spd limits introduced by earlier devices from affecting new devices. Signed-off-by: Tejun Heo <htejun@gmail.com>

* [PATCH] libata-hp-prep: make some ata_device fields persistentTejun Heo2006-05-31
| | | | | | | | | | | | | | | Lifetimes of some fields span over device plugging/unplugging. This patch moves such persistent fields to the top of ata_device and separate them with ATA_DEVICE_CLEAR_OFFSET. Fields above the offset are initialized once during host initializatino while all other fields are cleared before hotplugging. Currently ->ap, devno and part of flags are persistent. Note that flags is partially cleared while holding host_set lock. This is to synchronize with later warm plug implementation which will record hotplug request in dev->flags.

* [PATCH] libata-hp-prep: implement ata_dev_init()Tejun Heo2006-05-31
| | | | | | | | Move initialization of struct ata_device into ata_dev_init() in preparation for hotplug. This patch calls ata_dev_init() from ata_host_init() and thus makes no functional difference. Signed-off-by: Tejun Heo <htejun@gmail.com>
* [PATCH] libata: implement ata_eh_wait()Tejun Heo2006-05-31
| | | | | | | | | Implement ata_eh_wait().

* [PATCH] libata: set PIO-0 after successful EH resetTejun Heo2006-05-31
| | | | | | | | | Set ata_device->pio_mode to XFER_PIO_0 after a successful reset. This is to keep EH resets consistent with probe resets as updated by the commit b6079ca409bf88c248992e96510dd6f610f7ed89. Note that, with soon-to-follow hotplug update, EH resets will include probe resets. Signed-off-by: Tejun Heo <htejun@gmail.com>

| | | | | | | | | | | This patch sets the prerequisites for the new debugging scheme that more or less resembles Donald Becker's net driver example.
