2006-02-10[PATCH] sata_sil24: add hardresetTejun Heo
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>
2006-02-10[PATCH] sata_sil24: convert to new reset mechanismTejun Heo
Convert sata_sil24 ->phy_reset to new reset mechanism. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
2006-02-10[PATCH] libata: kill NULL qc handling from ->eng_timeout callbacksTejun Heo
->eng_timeout cannot be invoked with NULL qc anymore. Add an assertion in ata_scsi_error() and kill NULL qc handling from all ->eng_timeout callbacks. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
2006-02-10[PATCH] libata: use ata_scsi_timed_out()Tejun Heo
Make all libata low level drivers use ata_scsi_timed_out(). Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
2006-01-26[PATCH] libata: implement and apply ata_eh_qc_complete/retry()Tejun Heo
Implement ata_eh_qc_complete/retry() using scsi_eh_finish_cmd() and scsi_eh_flush_done_q(). This removes all eh scsicmd finish hacks from low level drivers. This change was first suggested by Jeff Garzik. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
2006-01-26[PATCH] libata: return AC_ERR_* from issue functionsTejun Heo
Return AC_ERR_* mask from issue fuctions instead of 0/-1. This enables things like failing a qc with AC_ERR_HSM when the device doesn't set DRDY when the qc is about to be issued. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
2006-01-26[PATCH] libata: add detailed AC_ERR_* flagsTejun Heo
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.

2005-12-06[PATCH] libata: move err_mask to ata_queued_cmdAlbert Lee
- remove err_mask from the parameter list of the complete functions - move err_mask to ata_queued_cmd - initialize qc->err_mask when needed - for each function call to ata_qc_complete(), replace the err_mask parameter with qc->err_mask.

2005-11-18[PATCH] sil24: make error_intr less verboseTejun Heo
sil24_error_intr logs all error interrupts. ATAPI devices generates many harmless errors which can be ignored and all serious ones are reported via sense data by SCSI layer. Don't log device errors from ATAPI devices. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
2005-11-18[PATCH] sil24: add ATAPI supportTejun Heo
This patch implements ATAPI support for sil24 and bumps driver version to 0.23. Signed-off-by: Tejun Heo <htejun@gmail.com> -- Jeff, it has been converted to use ->dev_config as pointed out. Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
2005-11-18[PATCH] sil24: use SRST for phy_resetTejun Heo
There seems to be no way to obtain device signature from sil24 after SATA phy reset and SRST is needed anyway for later port multiplier suppport. This patch converts sil24_phy_reset to use SRST instaed. Signed-off-by: Tejun Heo <htejun@gmail.com> -- Jeff, I didn't remove the 10ms sleep just to be on the safe side. I think we can live with 10ms sleep on SRST. Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
2005-11-18[PATCH] sil24: add sil24_restart_controllerTejun Heo
When an error condition is raised by device via D2H FIS or SDB. sil24 controller should be restarted by setting PORT_CS_INIT and waiting until PORT_CS_RDY is asserted instead of resetting the controller. This patch implements sil24_restart_controller for those cases. This patch also makes sure that PORT_CS_RDY is asserted on sil24_reset_controller completion. Signed-off-by: Tejun Heo <htejun@gmail.com> -- Jeff, delay is reduced to 1us and cnt increased to 10k. My sil3124 turns on PORT_CS_RDY on the second iteration even without any delay. I think 10k * 1us should be more than enough. I tried to convert both restart and reset to use msleep's with work queue, but if we do that, host_set lock should be released after initiating restart or reset, leading to race condition among reset/restart, other interrupts and timeout. Implementing synchronization among those in low-level driver doesn't seem right. Well, reduced timeout should work for the time being. Thanks. Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
2005-11-16[PATCH] sil24: add constantsTejun Heo

2005-11-13[PATCH] sil24: add missing ata_pad_free()Tejun Heo
sil24_port_stop() is missing call to ata_pad_free() thus leaking pad buffer when a port is stopped. This patch adds it. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

A few drivers were not following the standard meme of printing out their driver name and version at module load time; this is fixed as well.

2005-10-30[libata] change ata_qc_complete() to take error mask as second argJeff Garzik
The second argument to ata_qc_complete() was being used for two purposes: communicate the ATA Status register to the completion function, and indicate an error. On legacy PCI IDE hardware, the latter is often implicit in the former. On more modern hardware, the driver often completely emulated a Status register value, passing ATA_ERR as an indication that something went wrong. Now that previous code changes have eliminated the need to use drv_stat arg to communicate the ATA Status register value, we can convert it to a mask of possible error classes. This will lead to more flexible error handling in the future.

Enforce access rules where appropriate. If the compiler is smart enough, this may buy us an optimization or two as a side effect.

2005-10-09[libata sata_sil24] add support for 3131/3531Tejun Heo
This patch adds support for sil_3131 and sil_3531. Both are identical to 3124 except that they have only one port. Bits 30 and 31 of ata_port_info->host_flags is used to encode available port numbers. Version number is bumped to 0.22. Edward Falk supplied all the necessary information and preliminary patch.
