| | * [SERIAL] Remove incorrect code from ioc4 serial driverRussell King2006-02-101-14/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * | [PATCH] tty buffering stall fixPaul Fulghum2006-02-101-8/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prevent stalled processing of received data when a driver allocates tty buffer space but does not immediately follow the allocation with more data and a call to schedule receive tty processing. (example: hvc_console) This bug was introduced by the first locking patch for the new tty buffering.

* | [PATCH] sata_sil24: add hardresetTejun Heo2006-02-101-1/+10
| | | | | | | | | | | | | | | | | | Now that libata is smart enough to handle both soft and hard resets, add hardreset method. Note that sil24 hardreset doesn't supply signature; still, the new reset mechanism can make good use of it. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

| | | | | | | | | | | | | | | | Don't clear SError in sata_std_hardreset(). This makes hardreset act identically to ->phy_reset register-wise. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
* | [PATCH] libata: make new reset act identical to ->phy_reset register-wiseTejun Heo2006-02-101-17/+34
| | | | | | | | | | | | | | | | | | | | | | | | This patch makes std component operations act identical to ->phy_reset register-wise except for SError clearing on sata_std_hardreset. 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.

* | [PATCH] ahci: separate out ahci_fill_cmd_slot()Tejun Heo2006-02-101-21/+23
| | | | | | | | | | | | | | | | | | Separate out ahci_fill_cmd_slot() from ahci_qc_prep(). ahci_fill_cmd_slot() can later be used to issue non-standard commands. (e.g. softreset) Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

* | [PATCH] libata: implement ata_scsi_timed_out()Tejun Heo2006-02-102-0/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Garzik2006-01-271-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
