2006-03-04[PATCH] libata: convert dev->id to pointerTejun Heo1-1/+1
Convert dev->id from array to pointer. This is to accomodate revalidation. During revalidation, both old and new IDENTIFY pages should be accessible and single ->id array doesn't cut it. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-03-03[PATCH] libata: seperate out ata_class_present()Tejun Heo1-2/+6
Seperate out ata_class_present() from ata_dev_present(). This is useful because new reset mechanism deals with classes[] directly. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

2006-02-21[PATCH] libata: fix qc->n_elem == 0 case handling in ata_qc_next_sgTejun Heo1-2/+14
This patch makes ata_for_each_sg() start with pad_sgent when qc->n_elem is zero. Previously, ata_for_each_sg() unconditionally started with qc->__sg, handling the first sg to fill_sg() routines even when the entry was invalid. And while at it, unwind ?: in ata_qc_next_sg() into if statement. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

This patch renames ata_dev_id_[c_]string() to ata_id_[c_]string(). All other functions which read data from ATA ID data start with ata_id and those two function names were getting too long. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

2006-02-12[PATCH] libata: add per-device max_sectorsTejun Heo1-2/+2
If a low level driver wants to control max_sectors, it had to adjust ap->host->max_sectors and set ATA_DFLAG_LOCK_SECTORS to tell ata_scsi_slave_config not to override the limit. This is not only cumbersome but also incorrect for hosts which support more than one devices per port. This patch adds per-device ->max_sectors. If the field is unset (zero), libata core layer will adjust ->max_sectors according to default rules. If the field is set, libata honors the setting.

2006-02-12[PATCH] libata: move cdb_len for host to deviceTejun Heo1-1/+1
cdb_len is per-device property. Sharing cdb_len on ap results in inaccurate configuration on revalidation and hotplugging. This patch makes cdb_len per-device. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
2006-02-12[PATCH] libata: implement ata_dev_id_c_string()Tejun Heo1-0/+2
ata_dev_id_c_string() reads ATA string from the specified offset of the given IDENTIFY PAGE and puts it in the specified buffer in trimmed and NULL-terminated form. The caller must supply a buffer which is one byte larger than the maximum size of the target ID string. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

2006-02-10[PATCH] libata: implement ata_scsi_timed_out()Tejun Heo1-0/+1
Implement ata_scsi_timed_out(), to be used as scsi_host_template->eh_timed_out callback for all libata drivers. Without this function, the following race exists. If a qc completes after SCSI timer expires but before libata EH kicks in, the qc gets completed but the scsicmd still gets passed to libata EH resulting in ->eng_timeout invocation with NULL qc, which none is handling properly. This patch makes sure that scmd and qc share the same lifetime. Original idea from Jeff Garzik <jgarzik@pobox.com>.

2006-02-10[PATCH] libata: add ATA_QCFLAG_EH_SCHEDULEDTejun Heo1-0/+1
Add ATA_QCFLAG_EH_SCHEDULED. If this flag is set, the qc is owned by EH and normal completion path is not allowed to finish it. This patch doesn't actually use this flag. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

2006-02-09[PATCH] libata: implement ata_std_probeinit()Tejun Heo1-0/+1

2006-02-09[PATCH] libata: add probeinit component operation to ata_drive_probe_reset()Tejun Heo1-0/+2
This patch adds probeinit component operation to ata_drive_probe_reset(). If present, this new operation is called before performing any reset. The operations's roll is to prepare @ap for following probe-reset operations. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

2006-02-09[PATCH] libata: implement ATA_FLAG_IN_EH port flagTejun Heo1-0/+2
ATA_FLAG_IN_EH flag is set on entry to EH and cleared on completion. This patch just sets and clears the flag. Following patches will build normal qc execution / EH synchronization aroung this flag. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
2006-01-28[PATCH] libata: implement standard reset component operations and ->probe_resetTejun Heo1-0/+6

2006-01-28[PATCH] libata: implement ata_drive_probe_reset()Tejun Heo1-0/+5
Most low level drivers share supported reset/classify actions and sequence. This patch implements ata_drive_probe_reset() which helps constructing ->probe_reset from three component operations - softreset, hardreset and postreset. This minimizes duplicate code and yet allows flexibility if needed. The three component operations can also be shared by EH later.

2006-01-27[PATCH] libata: new ->probe_reset operationTejun Heo1-3/+5
Add new ->probe_reset operation to ata_port_operations obsoleting ->phy_reset. The main difference from ->phy_reset is that the new operation is not allowed to manipulate libata internals directly. It's not allowed to configure or disable the port or devices. It can only succeed or fail and classify attached devices into passed @classes. This change gives more control to higher level and eases sharing reset methods with EH. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

2006-01-27[PATCH] libata: add detailed AC_ERR_* flagsTejun Heo1-5/+10
Add detailed AC_ERR_* flags and use them. Long-term goal is to describe all errors with err_mask and tf combination (tf for failed sector information, etc...). After proper error diagnosis is implemented, sense data should also be generated from err_mask instead of directly from hardware tf registers as it is currently.

2006-01-27[PATCH] libata: return AC_ERR_* from issue functionsTejun Heo1-2/+2

2006-01-27[PATCH] libata: make the owner of a qc responsible for freeing itTejun Heo1-1/+1
qc used to be freed automatically on command completion. However, as a qc can carry information about its completion status, it can be useful to its owner/issuer after command completion. This patch makes freeing qc responsibility of its owner. This simplifies ata_exec_internal() and makes command turn-around for atapi request sensing less hackish.

2006-01-06[PATCH] Suspend support for libataJens Axboe1-0/+8
This patch adds suspend patch to libata, and ata_piix in particular. For most low level drivers, they should just need to add the 4 hooks to work. As I can only test ata_piix, I didn't enable it for more though. Suspend support is the single most important feature on a notebook, and most new notebooks have sata drives. It's quite embarrassing that we _still_ do not support this. Right now, it's perfectly possible to suspend the drive in mid-transfer.

2005-12-13[libata] mark certain hardware (or drivers) with a no-atapi flagJeff Garzik1-0/+1
Some hardware does not support the PACKET command at all. Other hardware supports ATAPI, but the driver does something nasty such as calling BUG() when an ATAPI command is issued. For these such cases, we mark them with a new flag, ATA_FLAG_NO_ATAPI. Initial version contributed by Ben Collins.
