sys/cam/scsi/scsi_all.h: In struct scsi_extended_inquiry_data: - Increase the length field to 2 bytes, as it is 2 bytes in SPC-4. - Add bit definitions for the various Activiate Microcode actions. - Add the Sequential Access Logical Block Protection support bit, since we need that in the sa(4) driver. (For modifications that will come later.) - Add definitions for the various Multi I_T Nexus Microcode Download modes. sys/cam/ctl/ctl.c: As of SPC-4, a single report of "REPORTED LUNS DATA HAS CHANGED" is to be given per I_T nexus. Once it is reported, the unit attention condition should be cleared for all LUNS attached to an I_T nexus. Previously that only happened when a REPORT LUNS command was processed. This behavior may be different (according to SAM-5) when the UA_INTLCK_CTRL bits are non-zero in the control mode page but CTL does not currently support that. So, in view of the spec, whenever we report a LUN inventory change unit attention, clear it on all LUNs for that particular I_T nexus. Add a new function, ctl_clear_ua() that will clear a unit attention on all LUNs for the given I_T nexus. One field in the extended inquiry data that we could potentially report at some point is the maximum supported sense data length. To do that, we would the SIM to report (via path inquiry perhaps) how much sense data it is able to send. Add comments to explain some of the bits that are set in the Extended Inquiry VPD page. Add a few comments to make it more clear which functions handle various VPD pages. Sponsored by: Spectra Logic MFC after: 1 week |

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 ``world'' target should only be used in cases where the source tree has not changed from the currently running version. See: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more information, including setting make(1) variables. 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.
