freebsd with flexible iflib nic queues

aic79xx.c: o Remove redundant ahd_update_modes() call. o Correct panic in diagnostic should state corruption cause the SCB Id to be invalid during a selection timeout. o Add workaround for missing BUSFREEREV feature in Rev A silicon. o Corect formatting nits. o Use register pretty printing in more places. o Save and restore our SCB pointer when updating the waiting queue list for an "expected" LQ-out busfree. o In ahd_clear_intstat, deal with the missing autoclear in the CLRLQO* registers. o BE fixup in a diagnostic printf. o Make sure that we are in the proper mode before disabling selections in ahd_update_pending_scbs. o Add more diagnostics. o task_attribute_nonpkt_tag -> task_attribute: we don't need a nonpkt_tag field anymore for allowing all 512 SCBs to be used in non-packetized connections. o Negotiate HOLD_MCS to U320 devices. o Add a few additional mode assertions. o Restore the chip mode after clearing out the qinfifo so that code using ahd_abort_scbs sees a consistent mode. o Simplify the DMA engine shutdown routine prior to performing a bus reset. o Perform the sequencer restart after a chip reset prior to setting up our timer to poll for the reset to be complete. On some OSes, the timer could actually pre-empt us and order is important here. o Have our "reset poller" set the expected mode since there is no guarantee of what mode will be in force when we are called from the OS timer. o Save and restore the SCB pointer in ahd_dump_card_state(). This routine must not modify card state. o Ditto for ahd_dump_scbs(). aic79xx.h: o Add a few more chip bug definitions. o Align our tag on a 32bit boundary. aic79xx.reg: aic79xx.seq: o Start work on removing workarounds for Rev B. o Use a special location in scratch from for stroring our SCBPTR during legacy FIFO allocations. This corrects problems in mixed packetized/non-packetized configurations where calling into a FIFO task corrupted our SCBPTR. o Don't rely on DMA priority to guarantee that all data in our FIFOs will flush prior to a command completion notification going out of the command channel. We've never seen this assumption fail, but better safe than sorry. o Deal with missing BUSFREEREV feature in H2A. o Simplify disconnect list code now that the list will always have only a single entry. o Implement the AHD_REG_SLOW_SETTLE_BUG workaround. o Swith to using "REG_ISR" for local mode scratch during our ISR. o Add a missing jmp to the data_group_dma_loop after our data pointers have been re-initialized by the kernel. o Correct test in the bitbucket code so that we actually wait for the bitbucket to complete before signaling the kernel of the overrun condition. o Reposition pkt_saveptrs to avoid a jmp instruction. o Update a comment to reflect that the code now waits for a FIFO to drain prior to issuing a CLRCHN. aic79xx_inline.h: o Remove unused untagged queue handling code. o Don't attempt to htole64 what could be a 32bit value. aic79xx_pci.c: o Set additional bug flags for rev A chips. |

This is the top level of the FreeBSD source directory. This file was last revised on: $FreeBSD$ For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information). The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree, the most commonly used one being ``world'', which rebuilds and installs everything in the FreeBSD system from the source tree except the kernel, the kernel-modules and the contents of /etc. The ``buildkernel'' and ``installkernel'' targets build and install the kernel and the modules (see below). Please see the top of the Makefile in this directory for more information on the standard build targets and compile-time flags. Building a kernel is a somewhat more involved process, documentation for which can be found at: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html And in the config(8) man page. Note: If you want to build and install the kernel with the ``buildkernel'' and ``installkernel'' targets, you might need to build world before. More information is available in the handbook. The sample kernel configuration files reside in the sys/<arch>/conf sub-directory (assuming that you've installed the kernel sources), the file named GENERIC being the one used to build your initial installation kernel. The file NOTES contains entries and documentation for all possible devices, not just those commonly used. It is the successor of the ancient LINT file, but in contrast to LINT, it is not buildable as a kernel but a pure reference and documentation file.
