Eliminate the use of commons in the kernel and modules, simplifying the module linking process and eliminating the risks associated with doubly-defined variables. Cases where commons were legitimately used (detection of compiled-in subsystems) have been converted to use sysinits, and any new code should use this or an equivalent practice as a matter of course. Modules can override this behaviour by substituting -fno-common out of ${CFLAGS} in cases where commons are necessary (eg. third-party object modules). Commons will be resolved and allocated space when the kld is linked as part of the module build process, so they will not pose a risk to the kernel or other modules. Provide a mechanism for controlling the export of symbols from the module namespace. The EXPORT_SYMS variable may be set in the Makefile to NO (export no symbols), a list of symbols to export, or the name of a file containing a newline-seperated list of symbols to be exported. Non-exported symbols are converted to local symbols. If EXPORT_SYMS is not set, all global symbols are currently exported. This behaviour is expected to change (to exporting no symbols) once modules have been converted. Reviewed by: peter (in principle) Obtained from: green (kmod_syms.awk)

This are the build infrastructure changes to allow to use the Intel C/C++ compiler (lang/icc) to build the kernel. The icc CPUTYPE CFLAGS use icc v7 syntax, icc v8 moans about them, but doesn't abort. They also produce CPU specific code (new instructions of the CPU, not only CPU specific scheduling), so if you get coredumps with signal 4 (SIGILL, illegal instruction) you've used the wrong CPUTYPE. Incarnations of this patch survive gcc compiles and my make universe. I use it on my desktop. To use it update share/mk, add /usr/local/intel/compiler70/ia32/bin (icc v7, works) or /usr/local/intel_cc_80/bin (icc v8, doesn't work) to your PATH, make sure you have a new kernel compile directory (e.g. MYKERNEL_icc) and run CFLAGS="-O2 -ip" CC=icc make depend CFLAGS="-O2 -ip" CC=icc make in it. Don't compile with -ipo, the build infrastructure uses ld directly to link the kernel and the modules, but -ipo needs the link step to be performed with Intel's linker. Problems with icc v8: - panic: npx0 cannot be emulated on an SMP system - UP: first start of /bin/sh results in a FP exception Parts of this commit contains suggestions or submissions from Marius Strobl <marius@alchemy.franken.de>.

Provide a knob for raising the inline instruction estimate threshold and set an initial value. This is aimed at getting us closer to being able to turn -Werror back on and we can adjust the settings later on. Yes, we could turn off -Wno-inline instead, but that would hide the effect of gcc's bogo-estimator ignoring inline (either rightly or wrongly).

Eliminate the use of commons in the kernel and modules, simplifying the module linking process and eliminating the risks associated with doubly-defined variables. Cases where commons were legitimately used (detection of compiled-in subsystems) have been converted to use sysinits, and any new code should use this or an equivalent practice as a matter of course. Modules can override this behaviour by substituting -fno-common out of ${CFLAGS} in cases where commons are necessary (eg. third-party object modules). Commons will be resolved and allocated space when the kld is linked as part of the module build process, so they will not pose a risk to the kernel or other modules. Provide a mechanism for controlling the export of symbols from the module namespace. The EXPORT_SYMS variable may be set in the Makefile to NO (export no symbols), a list of symbols to export, or the name of a file containing a newline-seperated list of symbols to be exported. Non-exported symbols are converted to local symbols. If EXPORT_SYMS is not set, all global symbols are currently exported. This behaviour is expected to change (to exporting no symbols) once modules have been converted. Reviewed by: peter (in principle) Obtained from: green (kmod_syms.awk)

Modules can override this behaviour by substituting -fno-common out of ${CFLAGS} in cases where commons are necessary (eg. third-party object modules). Commons will be resolved and allocated space when the kld is linked as part of the module build process, so they will not pose a risk to the kernel or other modules. Provide a mechanism for controlling the export of symbols from the module namespace. The EXPORT_SYMS variable may be set in the Makefile to NO (export no symbols), a list of symbols to export, or the name of a file containing a newline-seperated list of symbols to be exported. Non-exported symbols are converted to local symbols. If EXPORT_SYMS is not set, all global symbols are currently exported. This behaviour is expected to change (to exporting no symbols) once modules have been converted. Reviewed by: peter (in principle) Obtained from: green (kmod_syms.awk)

Merge bsd.obj.mk's version of the _SUBDIR target with bsd.subdir.mk. Ensure all standard targets honor SUBDIR. Now `make obj' descends into SUBDIRs even if NOOBJ is set (some descendants may still need an object directory, but we do not have such precedents). Now `make install' in non-bsd.subdir.mk makefiles runs `afterinstall' target _after_ `install' in SUBDIRs, like we do in bsd.subdir.mk. Nothing depended on the wrong order anyway. Fixed `distribute' targets (except for the bsd.subdir.mk version) so that they do not depend on _SUBDIR; `distribute' calls `install' which already depends on _SUBDIR. De-standardize `maninstall', otherwise manpages would be installed twice. (To be revised later.)

NOFSCHG will still be honoured by bsd.lib.mk but is valid for buildworld only. NOFSCHG is still implemented in the old way (ie. _not_ ".if NOFSCHG then { INSTALLFLAGS_EDIT+=:S/schg/,/ }" to emphasize the fact that NOFSCHG is only supported in a limited fashion and for buildworld. The interface and implementation are such that future use of flags such as sappnd can also be easily removed or altered (perhaps to uappnd).

Now, if kernel was configured for debugging (through DEBUG=-g in the kernel config file or "config -g"), doing "make install" will install debug versions of kernel and module objects with their canonical names, kernel.debug -> /boot/kernel/kernel if_fxp.ko.debug -> /boot/kernel/if_fxp.ko Installing a kernel not configured for debugging, or debug kernel with INSTALL_NODEBUG variable defined, will install non-debug kernel and module objects. Also, restore the install.debug and reinstall.debug targets that are part of the existing API (they cause some additional gdb(1) scripts to be installed).

This is the much rumoured ATA mkIII update that I've been working on. o ATA is now fully newbus'd and split into modules. This means that on a modern system you just load "atapci and ata" to get the base support, and then one or more of the device subdrivers "atadisk atapicd atapifd atapist ataraid". All can be loaded/unloaded anytime, but for obvious reasons you dont want to unload atadisk when you have mounted filesystems. o The device identify part of the probe has been rewritten to fix the problems with odd devices the old had, and to try to remove so of the long delays some HW could provoke. Also probing is done without the need for interrupts, making earlier probing possible. o SATA devices can be hot inserted/removed and devices will be created/ removed in /dev accordingly. NOTE: only supported on controllers that has this feature: Promise and Silicon Image for now. On other controllers the usual atacontrol detach/attach dance is still needed. o Support for "atomic" composite ATA requests used for RAID. o ATA RAID support has been rewritten and and now supports these metadata formats: "Adaptec HostRAID" "Highpoint V2 RocketRAID" "Highpoint V3 RocketRAID" "Intel MatrixRAID" "Integrated Technology Express" "LSILogic V2 MegaRAID" "LSILogic V3 MegaRAID" "Promise FastTrak" "Silicon Image Medley" "FreeBSD PseudoRAID" o Update the ioctl API to match new RAID levels etc. o Update atacontrol to know about the new RAID levels etc NOTE: you need to recompile atacontrol with the new sys/ata.h, make world will take care of that. NOTE2: that rebuild is done differently from the old system as the rebuild is now done piggybacked on read requests to the array, so atacontrol simply starts a background "dd" to rebuild the array. o The reinit code has been worked over to be much more robust. o The timeout code has been overhauled for races. o Support of new chipsets. o Lots of fixes for bugs found while doing the modulerization and reviewing the old code. Missing or changed features from current ATA: o atapi-cd no longer has support for ATAPI changers. Todays its much cheaper and alot faster to copy those CD images to disk and serve them from there. Besides they dont seem to be made anymore, maybe for that exact reason. o ATA RAID can only read metadata from all the above metadata formats, not write all of them (Promise and Highpoint V2 so far). This means that arrays can be picked up from the BIOS, but they cannot be created from FreeBSD. There is more to it than just the missing write metadata support, those formats are not unique to a given controller like Promise and Highpoint formats, instead they exist for several types, and even worse, some controllers can have different formats and its impossible to tell which one. The outcome is that we cannot reliably create the metadata of those formats and be sure the controller BIOS will understand it. However write support is needed to update/fail/rebuild the arrays properly so it sits fairly high on the TODO list. o So far atapicam is not supported with these changes. When/if this will change is up to the maintainer of atapi-cam so go there for questions. HW donated by: Webveveriet AS HW donated by: Frode Nordahl HW donated by: Yahoo!
