+ make Open_Disk sense the sector size by trying 512, 1024 and 2048 in this order. This makes the kernel note that dscheck(cd1): bio_bcount 512 is not on a sector boundary (ssize 2048) dscheck(cd1): bio_bcount 1024 is not on a sector boundary (ssize 2048) if 2048 is the sector size. If this worries anyone: the message is from /usr/src/sys/kern/subr_diskslice.c and shutups are to be placed there. + Have read_block and write_block use an additional parameter, the sector size. + replace all barfout calls with return NULL, 0, __LINE__, etc. Note that this does NOT emit diagnostics. More often than not, you don't want library functions to scribble on stderr -- it may not even be available. The right thing is to propagate the error condition to upper management. The app should take care of errors. + use d1->sector_size instead of 512 in various places. I've left many places untouched, especially those writing MBRs. I simply added another arg hardcoded as 512. This is because I would not know what I'm doing... I felt this approach would be reasonably backward compatible and not introduce any new bugs in critical software. Famous last words. Messing with MBRs might soon put me in the same screwup meister category as, uh, never mind. :-) + bump the max no of disks from 20 to 32 (due to PR 24503).

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/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 have to build world before. More information is available in the handbook. 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 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.
