Oops...forgot to list the changes.... /usr/src/usr.sbin.config: o -DSTATCLOCK gives kludges to support the rtc non-device as well as old kludges to support the clk non-device. /usr/src/usr.sbin/config.8: o Document the trivialness of the new vector.h. /usr/src/usr.sbin/mkglue.c: o Only print DEVICE_NAMES and NR_DEVICES in vector.h. These are only required to support vmstat. The vmstat interface will need to be improved for dynamic loading. /usr/src/usr.sbin/mkioconf.c: o Print device ids to be used as indexes into DEVICE_NAMES. o Print secondary interrupt handler entry points (xxxintr()) instead of primary ones (VdevU()). Primary ones are now XintrI() and XfastintrI() and are independent of the config so they are not handled here. o Minor cleanups.

Allow config to be compiled from another source directory, such as one for building tools. This boils down to replacing ${.CURDIR} with ${SRCDIR}, where the latter is the directory in which this makefile lives. Also allow overriding where file2c comes from using ${FILE2C}. 2016-10-26 15:58:41 +00:00			`SRCDIR:=${.PARSEDIR:tA}`

config: drop dependency on libnv Compile mkmakefile.c as C++ instead and use an std::unordered_map to accomplish the same goal. Reviewed by: imp Sponsored by: Klara, Inc. Sponsored by: NetApp, Inc.

config.5 was repocopied from share/man/man5/ to usr.sbin/config/. Repocopied by: peter 2005-12-09 06:46:41 +00:00			`MAN= config.5 config.8`
config: drop dependency on libsbuf Use an std::stringstream instead. get_word() and get_quoted_word() both return a buffer that's presumed to not need release, so solve this by returning a new special configword type that holds a string or eof/eol state. This cleans up caller checking for EOF/EOL to make it more explicit what they're doing, at least in the EOL cases which previously checked for NULL. Sponsored by: Klara, Inc.

Improve INCLUDE_CONFIG_FILE support. This change will let us to have full configuration of a running kernel available in sysctl: sysctl -b kern.conftxt The same configuration is also contained within the kernel image. It can be obtained with: config -x <kernelfile> Current functionality lets you to quickly recover kernel configuration, by simply redirecting output from commands presented above and starting kernel build procedure. "include" statements are also honored, which means options and devices from included files are also included. Please note that comments from configuration files are not preserved by default. In order to preserve them, you can use -C flag for config(8). This will bring configuration file and included files literally; however, redirection to a file no longer works directly. This commit was followed by discussion, that took place on freebsd-current@.

Perform a major cleanup of the usr.sbin Makefiles. These are not perfectly in agreement with each other style-wise, but they are orders of orders of magnitude more consistent style-wise than before. 2001-07-20 06:20:32 +00:00
config(8): Fix broken ABI r336019 introduced ${SRCTOP}/sys to the include paths in order to pull in a new sys/{c,}nv.h. This is wrong, because the build tree's ABI isn't guaranteed to match what's running on the host system. Fix instead by removing -I${SRCTOP}/sys and installing the libnv headers with `make -C lib/libnv includes`... this may or may not get re-worked in the future so that a userland lib isn't installing includes from sys/.

Add the Clang specific -Wmissing-variable-declarations to WARNS=6. This compiler flag enforces that that people either mark variables static or use an external declarations for the variable, similar to how -Wmissing-prototypes works for functions. Due to the fact that Yacc/Lex generate code that cannot trivially be changed to not warn because of this (lots of yy* variables), add a NO_WMISSING_VARIABLE_DECLARATIONS that can be used to turn off this specific compiler warning.

Clean up the -g/DEBUG handling. This logic can go in the Makefile so that config -g can work the same as: makeoptions DEBUG="-g" 1999-04-13 18:22:57 +00:00			`mkmakefile.o: configvers.h`
For safety's sake, explicitly depend all objects on the configvers.h header to make sure that it's all recompiled even if there is no 'make depend'. This is overkill, but should be one less thing that someone can do wrong. 1997-10-22 00:44:08 +00:00
