2019-06-13decodetree: Fix comparison of FieldRichard Henderson
Typo comparing the sign of the field, twice, instead of also comparing the mask of the field (which itself encodes both position and length).

2019-06-12qapi: Simplify how QAPIDoc implements its state machineMarkus Armbruster
QAPIDoc uses a state machine to for processing of documentation lines. Its state is encoded as an enum QAPIDoc._state (well, as enum-like class actually, thanks to our infatuation with Python 2). All we ever do with the state is calling the state's function to process a line of documentation. The enum values effectively serve as handles for the functions. Eliminate the rather wordy indirection: store the function to call in QAPIDoc._append_line. Update and improve comments.

2019-06-12qapi: Disentangle QAPIDoc codeKevin Wolf
Documentation comments follow a certain structure: First, we have a text with a general description (called QAPIDoc.body). After this, descriptions of the arguments follow. Finally, we have a part that contains various named sections. The code doesn't show this structure, but just checks various attributes that indicate indirectly which part is being processed, so it happens to do the right set of things in the right phase. This is hard to follow, and adding support for documentation of features would be even harder. This patch restructures the code so that the three parts are clearly separated. The code becomes a bit longer, but easier to follow. The resulting output remains unchanged.

2019-06-12qapi: Add feature flags to struct typesKevin Wolf
Sometimes, the behaviour of QEMU changes without a change in the QMP syntax (usually by allowing values or operations that previously resulted in an error). QMP clients may still need to know whether they can rely on the changed behavior. Let's add feature flags to the QAPI schema language, so that we can make such changes visible with schema introspection. An example for a schema definition using feature flags looks like this: { 'struct': 'TestType', 'data': { 'number': 'int' }, 'features': [ 'allow-negative-numbers' ] } Introspection information then looks like this: { "name": "TestType", "meta-type": "object", "members": [ { "name": "number", "type": "int" } ], "features": [ "allow-negative-numbers" ] } This patch implements feature flags only for struct types. We'll implement them more widely as needed.

In commit f2a3b549e357041f86d7e we updated our u-boot blob and sources to v2019.01, which no longer has this problem, so we can finally remove our workaround (effectively reverting d0dead3b6df7f6cd970e).

2019-03-07minikconfig: implement allnoconfig and defconfig modesPaolo Bonzini
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.

2019-03-07build: switch to KconfigPaolo Bonzini
The make_device_config.sh script is replaced by minikconf, which is modified to support the same command line as its predecessor. The roots of the parsing are default-configs/*.mak, Kconfig.host and hw/Kconfig. One difference with make_device_config.sh is that all symbols have to be defined in a Kconfig file, including those coming from the configure script. This is the reason for the Kconfig.host file introduced in the previous patch. Whenever a file in default-configs/*.mak used $(...) to refer to a config-host.mak symbol, this is replaced by a Kconfig dependency; this part must be done already in this patch for bisectability.

2019-03-07kconfig: introduce kconfig filesPaolo Bonzini
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.

2019-03-07minikconfig: add semantic analysisPaolo Bonzini
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.

2019-03-07minikconfig: add parser skeletonPaolo Bonzini
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.

2019-03-05qapi: Fix array first used in a different moduleMarkus Armbruster
We generally put implicitly defined types in whatever module triggered their definition. This is wrong for array types, as the included test case demonstrates. Let's have a closer look at it. Type 'Status' is defined sub-sub-module.json. Array type ['Status'] occurs in main module qapi-schema-test.json and in include/sub-module.json. The main module's use is first, so the array type gets put into the main module. The generated C headers define StatusList in qapi-types.h. But include/qapi-types-sub-module.h uses it without including qapi-types.h. Oops. To fix that, put the array type into its element type's module. Now StatusList gets generated into qapi-types-sub-module.h, which all its users include.

2019-03-05qapi: Fix code generation for sub-modules in other directoriesMarkus Armbruster
The #include directives to pull in sub-modules use file names relative to the main module. Works only when all modules are in the same directory, or the main module's output directory is in the compiler's include path. Use relative file names instead. The dummy variable we generate to avoid empty .o files has an invalid name for sub-modules in other directories. Fix that. Both messed up in commit 252dc3105fc "qapi: Generate separate .h, .c for each module". Escaped testing because tests/qapi-schema-test.json doesn't cover sub-modules in other directories, only tests/qapi-schema/include-relpath.json does, and we generate and compile C code only for the former, not the latter. Fold the latter into the former. This would have caught the mistakes fixed in this commit.
