for optimizing the unpause operation no-longer exist, and this is much safer. When restarting the sequencer, reconstitute the free SCB list on the card. This deals with a single instruction gap between marking the SCB as free and actually getting it onto the free list. Reduce the number of transfer negotiations that occur. In the past, we renegotiated after every reported check condition status. This ensures that we catch devices that have unexpectidly reset. In this situation, the target will always report the check condition before performing a data-phase. The new behavior is to renegotiate for any check-condition where the residual matches the orginal data-length of the command (including 0 length transffers). This avoids renegotiations during things like variable tape block reads, where the check condition is reported only to indicate the residual of the read. Revamp the parity error detection logic. We now properly report and handle injected parity errors in all phases. The old code used to hang on message-in parity errors. Correct the reporting of selection timeout errors to the XPT. When a selection timeout occurs, only the currently selecting command is flagged with SELTO status instead of aborting all currently active commands to that target. Fix flipped arguments in ahc_match_scb and in some of the callers of this routine. I wish that gcc allowed you to request warnings for enums passed as ints. Make ahc_find_msg generically handle all message types. Work around the target mode data-in wideodd bug in all non-U2 chips. We can now do sync-wide target mode transfers in target mode across the hole product line. Use lastphase exclusively for handling timeouts. The current phase doesn't take the bus free state into account. Fix a bug in the timeout handler that could cause corruption of the disconnected list. When sending an embedded cdb to a target, ensure that we start on a quad word boundary in the data-fifo. It seems that unaligned stores do not work correctly. |

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 and the contents of /etc. 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 with config(8) is a somewhat more involved process, documentation for which can be found at: http://www.freebsd.org/handbook/kernelconfig.html And in the config(8) man page. The sample kernel configuration files reside in the sys/i386/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 LINT contains entries for all possible devices, not just those commonly used, and is meant more as a general reference than an actual kernel configuration file (a kernel built from it wouldn't even run).
