Paolo Bonzini	f9423e9f0a	minikconf: print error entirely on stderr While debugging an invalid configuration, I noticed that the clauses debug ends up on stderr but the header ("The following clauses were found..." ends up on stdout. This makes the contents of meson-logs/meson-log.txt a bit confusing. Reviewed-by: Philippe Mathieu-Daudé <philmd@linaro.org> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>	2 years ago

Stefan Hajnoczi	ddd633e525	minikconf: explicitly set encoding to UTF-8 QEMU currently only has ASCII Kconfig files but Linux actually uses UTF-8. Explicitly specify the encoding and that we're doing text file I/O. It's unclear whether or not QEMU will ever need Unicode in its Kconfig files. If we start using the help text then it will become an issue sooner or later. Make this change now for consistency with Linux Kconfig.

Marc-André Lureau	c5b35f03c3	minikconf: don't print CONFIG_FOO=n lines qemu in general doesn't define CONFIG_FOO if it's false. This also helps with the dumb kconfig parser from meson, as source_set considers any non-empty value as true.

Paolo Bonzini	6b7ac49d57	minikconf: do not include variables from MINIKCONF_ARGS in config-all-devices.mak When minikconf writes config-devices.mak, it includes all variables including those from MINIKCONF_ARGS. This causes values from config-host.mak to "stick" to the ones used in generating config-devices.mak, because config-devices.mak is included after config-host.mak. Avoid this by omitting assignments coming from the command line in the output of minikconf.

Paolo Bonzini	67163caeba	minikconf: fix parser typo The result of this typo would be that "select_foo" would be treated as a "select" keyword followed by "_foo". Nothing too bad, but easy to fix so let's be clean. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>	8 years ago
Paolo Bonzini	f349474920	minikconfig: implement allnoconfig and defconfig modes Apart from defconfig (which is a no-op), allyesconfig/allnoconfig/randcondfig can be implemented simply by ignoring the RHS of assignments and "default" statements. The RHS is replaced respectively by "true", "false" or a random value. However, allyesconfig and randconfig do not quite work, because all the files for hw/ARCH/Kconfig are sourced and therefore you could end up enabling some ARM boards in x86 or things like that. This is left for future work, but I am leaving it in to help debugging minikconf itself. allnoconfig mode is tied to a new configure option, --without-default-devices.

Paolo Bonzini	82f5181777	kconfig: introduce kconfig files The Kconfig files were generated mostly with this script: for i in `grep -ho CONFIG_[A-Z0-9_]* default-configs/* \| sort -u`; do set fnord `git grep -lw $i -- 'hw//Makefile.objs' ` shift if test $# = 1; then cat >> $(dirname $1)/Kconfig << EOF config ${i#CONFIG_} bool EOF git add $(dirname $1)/Kconfig else echo $i $ fi done sed -i '$d' hw//Kconfig for i in hw/; do if test -d $i && ! test -f $i/Kconfig; then touch $i/Kconfig git add $i/Kconfig fi done Whenever a symbol is referenced from multiple subdirectories, the script prints the list of directories that reference the symbol. These symbols have to be added manually to the Kconfig files. Kconfig.host and hw/Kconfig were created manually.

Paolo Bonzini	f7082a9a7c	minikconfig: add semantic analysis There are three parts in the semantic analysis: 1) evaluating expressions. This is done as a simple visit of the Expr nodes. 2) ordering clauses. This is done by constructing a graph of variables. There is an edge from X to Y if Y depends on X, if X selects Y, or if X appears in a conditional selection of Y; in other words, if the value of X can affect the value of Y. Each clause has a "destination" variable whose value can be affected by the clause, and clauses will be processed according to a topological sorting of their destination variables. Defaults are processed after all other clauses with the same destination. 3) deriving the value of the variables. This is done by processing the clauses in the topological order provided by the previous step. A "depends on" clause will force a variable to False, a "select" clause will force a variable to True, an assignment will force a variable to its RHS. A default will set a variable to its RHS if it has not been set before. Because all variables have a default, after visiting all clauses all variables will have been set.

Paolo Bonzini	d4fdccadba	minikconfig: add parser skeleton This implements a scanner and recursive descent parser for Kconfig-like configuration files. The only "action" of the parser is for now to detect undefined variables and process include files. The main differences between Kconfig and this are: * only the "bool" type is supported * variables can only be defined once * choices are not supported (but they could be added as syntactic sugar for multiple Boolean values) * menus and other graphical concepts (prompts, help text) are not supported * assignments ("CONFIG_FOO=y", "CONFIG_FOO=n") are parsed as part of the Kconfig language, not as a separate file. The idea was originally by Ákos Kovács, but I could not find his implementation so I had to redo it.
