| H A D | ncr53c9x.c | diff 182876 Mon Sep 08 18:21:05 MDT 2008 marius o Move the MODULE_DEPEND() for cam(4) from the esp_sbus.c front-end to the ncr53c9x.c core where it actually belongs so future front-ends don't need to add it. o Use the correct OFW property when looking for the initiator ID of the SBus device. o Don't specify an alignment when creating the parent DMA tag for SUNW,fas; their DMA engine doesn't require an alignment constraint and it's no inherited by the child DMA tags anyway (which probably is a bug though). o Drop the superfluous sc_maxsync and use sc_minsync instead. The former apparently was added due to a confusion with the maximum frequency used in cam(4), which basically corresponds to the inverse of minimum sync period. o Merge ncr53c9x.c from NetBSD: 1.116: NCRDMA_SETUP() should be called before NCR_SET_COUNT() and NCRCMD_DMA command in ncr53c9x_select(). 1.125: free allocated resources on detach. o Static'ize ncr53c9x_action(), ncr53c9x_init() and ncr53c9x_reset() as these are not required outside of ncr53c9x.c. o In ncr53c9x_attach() don't leak the device mutex in case attaching fails. o Register an asynchronous notification handler so in case cam(4) reports a lost device we can cancel outstanding commands and restore the default parameters for the target in question. o For FAS366 correctly support 16-bit target IDs and let it know that we use 32-bit transfers. o Overhaul the negotiation of transfer settings. This includes distinguishing between current and goal transfer settings of the target so we can renegotiate their goal settings when necessary and correcting the order in which tagged, wide and synchronous transfers are negotiated. o If we are requesting sense, force a renegotiation if we are currently using anything different from asynchronous at 8 bit as the target might have lost our transfer negotiations. o In case of an XPT_RESET_BUS just directly call ncr53c9x_init() instead of issuing a NCRCMD_RSTSCSI, which in turn will issue an interrupt that is treated as an unexpected SCSI bus reset by ncr53c9x_intr() and thus calls ncr53c9x_init(). Remove the now no longer used ncr53c9x_scsi_reset(). o Correct an off-by-one error when setting cpi->max_lun. o In replace printf(9) with device_printf(9) calls where appropriate and in ncr53c9x_action() remove some unnecessarily verbose messages. o In ncr53c9x_sched() use TAILQ_FOREACH() instead of reimplementing it and consolidate two tagging-related target info checks into one. o In ncr53c9x_done() set the CAM status to CAM_SCSI_STATUS_ERROR when appropriate, respect CAM_DIS_AUTOSENSE and teach it to return SCSI status information. o In ncr53c9x_dequeue() ensure the tags are cleared. o Use ulmin() instead of min() where appropriate. o In ncr53c9x_msgout() consistently use the reset label. o When we're interrupted during a data phase and the DMA engine is still active, don't panic but reset the core and the DMA engine as this should be sufficient. Also, the typical problem for triggering this was the lack of renegotiation when requesting sense. o Correctly handle DEVICE RESETs. o Adapt the locking of esp(4) to MPSAFE cam(4). This includes moving the calls of lsi64854_attach() to the bus front-ends so it can pass the esp(4) mutex to bus_dma_tag_create(9). o Change the LSI64854 driver to not create a DMA tag and map for the Ethernet channel as le(4) will handle these on its own as well as sync and unload the DMA maps for the SCSI and parallel port channel after a DMA transfer. o Cam(4)'ify some NetBSD-centric comments. o Use bus_{read,write}_*(9) instead of bus_space_{read,write}_*(9) and take advantage of rman_get_rid(9) in order to save some softc members.
