Switch to using the same AHC_SHOW_XXX format as the ahd driver. Always give the target a MSG_INITIATOR_DET_ERR for unexpected DT or ST phase errors. Add AHC_SHOW_SELTO diagnostics. Force renegotiation whenever an unexpected bus free occurs to rule out a negotiation mismatch as the cause for the error. Use "offset != 0" as an intenal indicator of "async" rather than using a period of 0. In ahc_fetch_devinfo(), correct a bug in getting "our id" as target. We weren't looking at all the SEQ_FLAGS that indicate that we are still in a selected rather than reselected state. Add support for the AHC_SHOW_MESSAGES debugging option. If ahc_parse_msg() tells us to terminate the message loop, do so without acking the message. The message may be one that the sequencer needs to handle on its own. In ahc_parse_msg() return MSGLOOP_TERMINATED for all messages the sequencer handles. Allocate storage for, and track, seeprom contents in our softc. Touch all SCB bytes to avoid parity errors should one of our debugging routines read an otherwise uninitiatlized byte. S/G lists must be 8 byte aligned. Reflect this in our DMA tag. "the the" -> "the" in a comment When pausing the card to perform error recovery, ensure that we are not in the process of being selected or have just been selected but have not yet handled that selection. This leaves only one other race window, in the command complete handler, that needs to be fixed to make recovery 100% bullet proof. Convert a few straglers from bsd u_intX_t to inttypes uintX_t. Remove unused variables. Split out searching of the untagged holding queues to its own routine. In certain recovery scenarios, we want to just remove entries in the untagged queue without touching related transactions that are in the QINFIFO or WAITING queues that are searched by ahc_search_qinfifo(). Add an implementation of the ahc_print_register() routine which "pretty prints" registers. The extra bloat in the form of string tables for this feature is controlled by the AHC_REG_PRETTY_PRINT option. Fix a few bugs in ahc_enable_lun() that could prevent controllers lacking the multiple-target-id feature from changing "our id" on the fly. Add a large comment to this section while I'm here describing the restrictions on "id switching". |

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.
