* [PATCH] libata: add per-device max_sectorsTejun Heo2006-02-12
| | | | | | | | | | | | | | | 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.

* [PATCH] libata: move cdb_len for host to deviceTejun Heo2006-02-12
| | | | | | | | | 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>
* [PATCH] libata: make ata_dev_knobble() per-deviceTejun Heo2006-02-12
| | | | | | | | | | ata_dev_knobble() unconditionally used the first device of the port to determine whether a device is bridged or not. This causes bridge limit to be incorrectly applied or unapplied for hosts with slave devices (e.g. ata_piix).

* [PATCH] libata: convert assert(X)'s in libata core layer to WARN_ON(!X)'sTejun Heo2006-02-11
| | | | | | | | | | | | | | | | | | | In an effort to kill libata-specific assert() and use generic WARN_ON(), this patch converts all assert(X)'s in libata core layer to WARN_ON(!X)'s. Most conversions are straight-forward logical negation exception for the followings. * In libata-core.c:ata_fill_sg(), assert(qc->n_elem > 0) is converted to WARN_ON(qc->n_elem == 0) because qc->n_elem is unsigned and unsigned <= 0 is weird. * In libata-scsi.c:ata_gen_ata_desc/fixed_sense(), assert(NULL != qc->ap->ops->tf_read) is converted to WARN_ON(qc->ap->ops->tf_read == NULL), as there are no other users of 'constant cond var' style in libata.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Serial drivers in general should not write uart_info->flags - they're private to serial_core. Serial drivers have no need to fiddle with tty->alt_speed, nor manipulate TTY_IO_ERROR in tty->flags. Fix the ioc4 serial driver for both these points by simply removing the offending code.

Note that if a driver only implements/uses hardreset, it should not use ata_std_probeinit() to avoid extra sata_phy_resume() and ata_busy_sleep() compared to ->phy_reset.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>.

| * | [libata sata_sil] implement 'slow_down' module parameterJeff Garzik2006-01-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On occasion, a user will submit a patch that enables the "mod15write" quirk for their device. Enabling this quirk has the effect of clamping all ATA commands to no more than 15 sectors. The intended use of this quirk is to stop the controller from generating FIS's of unusual size ("but Wesley, what about the FOUS's?"), which in turn works around problems in a <list> of hard drives. One side effect of this quirk is greatly decreased performance. Users often enable the mod15write quirk to fix various system, power, chip, and/or driver problems. For a few rare problematic cases, enabling this has cured lockups or data corruption. Rather than add bogus listings to the mod15write quirk list (I get a patch every month doing such), we add a 'slow_down' module parameter. This allows users to employ a performance sledgehammer in the hopes of curing a problem. It defaults to off (0), of course.
