using 512 byte blocks). cam_ccb.h: Bump up volume_size and cylinders in ccb_calc_geometry to 64 bits and 32 bits respectively, so we can hold larger device sizes. cylinders would overflow at about 500GB. Bump CAM_VERSION for this change. Note that this will require a recompile of all applications that talk to the pass(4) driver. scsi_all.c: Add descriptions for READ/WRITE(16), update READ/WRITE(12) descriptions, add descriptions for SERVICE ACTION IN/OUT. Add a new function, scsi_read_capacity_16(), that issues the read capacity service action. (Necessary for arrays larger than 2^32 sectors.) Update scsi_read_write() to use a 64 bit LBA and issue READ(16) or WRITE(16) if necessary. NOTE the API change. This should be largely transparnet to most userland applications at compile time, but will break binary compatibility. The CAM_VERSION bump, above, also serves the purpose of forcing a recompile for any applications that talk to CAM. scsi_all.h: Add 16 byte READ/WRITE structures, structures for 16 byte READ CAPACITY/SERVICE ACTION IN. Add scsi_u64to8b() and scsi_8btou64. scsi_da.c: The da(4) driver probe now has two stages for devices larger than 2TB. If a standard READ CAPACITY(10) returns 0xffffffff, we issue the 16 byte version of read capacity to determine the true array capacity. We also do the same thing in daopen() -- use the 16 byte read capacity if the device is large enough. The sysctl/loader code has also been updated to accept 16 bytes as a minimum command size.
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.
