| H A D | cam_periph.h | diff 47412 Sat May 22 19:58:47 MDT 1999 gibbs Add the XPT_PATH_STATS and XPT_GDEV_STATS function codes. These ccb types allow the reporting of error counts and other statistics. Currently we provide information on the last BDR or bus reset as well as active transaction inforamtion, but this will be expanded as more information is added to aid in error recovery. Use the 'last reset' information to better handle bus settle delays. Peripheral drivers now control whether a bus settle delay occurs and for how long. This allows target mode peripheral drivers to avoid having their device queue frozen by the XPT for what shoudl only be initiator type behavior. Don't perform a bus reset if the target device is incapable of performing transfer negotiation (e.g. Fiber Channel). If we don't perform a bus reset but the controller is capable of transfer negotiations, force negotiations on the first transaction to go to the device. This ensures that we aren't tripped up by a left over negotiation from the prom, BIOS, loader, etc. Add a default async handler funstion to cam_periph.c to remove duplicated code in all initiator type peripheral drivers. Allow mapping of XPT_CONT_TARGET_IO ccbs from userland. They are itentical to XPT_SCSI_IO ccbs as far as data mapping is concerned. |
