- Add periodic status monitoring routine. Currently just detects lost commands, further functionality pending data from AMI. Add some new commands states; WEDGED (never coming back) and LATE (for when a command that wasmarked as WEDGED comes bacj, - Remove a number of redundant efforts to poll the card for completed commands. This is what interrupt handlers are for. - Limit the maximum number of outstanding I/O transactions. It seems that some controllers report more than they can really handle, and exceding this limit can cause the controller to lock up. - Don't use 'wait' mode for anything where the controller might not be able to generate interrupts. (Keep the 'wait' mode though sa it will become useful when we start taking userspace commands. - Use a similar atomic locking trategy to the Mylex driver to prevent some reentrancy problems. - Correctly calculate the block count for non-whoile-bloch transfers (actually illegal). - Use the dsik device's si_drv1 field instead of b_driver1 in the buf struct to pass the driver identifier arond. - Rewrite amr_start and amr_done() along the lines of the Mylex driver in order to improve robustnes. - Always force the PCI busmaster bit on.
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).
