which depends on cam(4) revision r195534. The change have been tested on stable/7 with 3ware 9650SE at iXsystems.

Don't use pack() for structures that is used purely for software state. Otherwise the resulting, unaligned mutex structure would trigger panic. Submitted by: Tom Cough Reported/Tested by: jhb PR: kern/148464

Driver update of twa(4) from LSI. Many thanks to LSI for continuing to support FreeBSD. 1) Timeout ioctl command timeouts. Do not reset the controller if ioctl command completed successfully. 2) Remove G66_WORKAROUND code (this bug never shipped). 3) Remove unnecessary interrupt lock (intr_lock). 4) Timeout firmware handshake for PChip reset (don't wait forever). 5) Handle interrupts inline. 6) Unmask command interrupt ONLY when adding a command to the pending queue. 7) Mask command interrupt ONLY after removing the last command from the pending queue. 8) Remove TW_OSLI_DEFERRED_INTR_USED code. 9) Replace controller "state" with separate data fields to avoid races: TW_CLI_CTLR_STATE_ACTIVE ctlr->active TW_CLI_CTLR_STATE_INTR_ENABLED ctlr->interrupts_enabled TW_CLI_CTLR_STATE_INTERNAL_REQ_BUSY ctlr->internal_req_busy TW_CLI_CTLR_STATE_GET_MORE_AENS ctlr->get_more_aens TW_CLI_CTLR_STATE_RESET_IN_PROGRESS ctlr->reset_in_progress TW_CLI_CTLR_STATE_RESET_PHASE1_IN_PROGRESS ctlr->reset_phase1_in_progress 10) Fix "req" leak in twa_action() when simq is frozen and req is NOT null. 11) Replace softc "state" with separate data fields to avoid races: TW_OSLI_CTLR_STATE_OPEN sc->open TW_OSLI_CTLR_STATE_SIMQ_FROZEN sc->simq_frozen 12) Fix reference to TW_OSLI_REQ_FLAGS_IN_PROGRESS in tw_osl_complete_passthru() 13) Use correct CAM status values. Change CAM_REQ_CMP_ERR to CAM_REQ_INVALID. Remove use of CAM_RELEASE_SIMQ for physical data addresses. 14) Do not freeze/ release the simq with non I/O commands. When it is appropriate to temporarily freeze the simq with an I/O command use: xpt_freeze_simq(sim, 1); ccb->ccb_h.status |= CAM_RELEASE_SIMQ; otherwise use: xpt_freeze_simq(sim, 1); xpt_release_simq(sim, 1); Submitted by: Tom Couch PR: kern/147694

MFC: Reenable 64-bit DMA for twa(4) controllers, but use a boundary of 4GB

to prevent individual transactions from crossing a 4GB address boundary. Due to bus_size_t type limitations, the driver uses a 2GB boundary in PAE kernels. Approved by: re (kensmith)

Prepare for future integration between CAM and newbus. xpt_bus_register

2007-06-17T05:55:54Z

now takes a device_t to be the parent of the bus that is being created. Most SIMs have been updated with a reasonable argument, but a few exceptions just pass NULL for now. This argument isn't used yet and the newbus integration likely won't be ready until after 7.0-RELEASE.

something that I wasn't aware of with the last import. Adjust the string accordingly for 7-CURRENT.
