Greg Manning	d5f207ea47	plugins: disable lockstep plugin on windows The lockstep plugin uses unix sockets and would require a different communication mechanism to work on Windows.

Greg Manning	330fe3b03f	plugins: make test/example plugins work on windows Generate a qemu_plugin_api.lib delay import lib on windows, for windows qemu plugins to link against. Implement an example dll load fail hook to link up the API functions correctly when a plugin is loaded on windows. Update the build scripts for the test and example plugins to use these things.

Paolo Bonzini	bafe78ad3b	contrib/plugins: use an independent makefile The initial reason to write this patch was to remove the last use of CONFIG_DEBUG_TCG from the makefiles; the flags to use to build TCG plugins are unrelated to --enable-debug-tcg, and instead they should be the same as those used to build emulators (the plugins are not build via meson for demonstration reasons only). However, since contrib/plugins/Makefile is also the last case of doing a compilation job using config-host.mak, go a step further and make it use a completely separate configuration file, removing all references to compilers from the toplevel config-host.mak. Clean up references to empty variables, and use .SECONDARY so that intermediate object files are not deleted. Reviewed-by: Daniel P.

Paolo Bonzini	f6feb021e2	contrib/plugins: add Darwin support Under Darwin, using -shared makes it impossible to have undefined symbols and -bundle has to be used instead; so detect the OS and use different options.

Paolo Bonzini	07c4523c6c	contrib/plugins: remove -soname argument -soname is not needed for runtime-loaded modules. For example, Meson says: if not isinstance(target, build.SharedModule) or target.force_soname: # Add -Wl,-soname arguments on Linux, -install_name on OS X commands += linker.get_soname_args( self.environment, target.prefix, target.name, target.suffix, target.soversion, target.darwin_versions) (force_soname is set is shared modules are linked into a build target, which is not the case here.

Paolo Bonzini	95caf1fb42	build: move warning flag selection to meson Meson already knows to test with the positive form of the flag, which simplifies the test. Warnings are now tested explicitly for the C++ compiler, instead of hardcoding those that are only available for the C language. At this point all compiler flags in QEMU_CFLAGS are global and only depend on the OS. No feature tests are performed in configure.

Paolo Bonzini	fc9a809e0d	build: move glib detection and workarounds to meson QEMU adds the path to glib.h to all compilation commands. This is simpler due to the pervasive use of static_library, and was grandfathered in from the previous Make-based build system. Until Meson 0.63 the only way to do this was to detect glib in configure and use add_project_arguments, but now it is possible to use add_project_dependencies instead. gmodule is detected in a separate variable, with export enabled for modules and disabled for plugin.

Alex Bennée	a4cc0b7dd7	contrib/plugins: enable debug on CONFIG_DEBUG_TCG We used to rely on QEMU_CFLAGS to expose the debug flags but now this is synthesised by meson and only available to the main build. Add our own flags if we detect the build has been enabled with CONFIG_DEBUG_TCG (which is the default for --enable-debug anyway).

Mahmoud Mandour	e2c5557ce1	plugins: Added a new cache modelling plugin Added a cache modelling plugin that uses a static configuration used in many of the commercial microprocessors and uses random eviction policy.

Alex Bennée	a622d64eea	plugins: new hwprofile plugin This is a plugin intended to help with profiling access to various bits of system hardware. It only really makes sense for system emulation. It takes advantage of the recently exposed helper API that allows us to see the device name (memory region name) associated with a device. You can specify arg=read or arg=write to limit the tracking to just reads or writes (by default it does both). The pattern option: -plugin ./tests/plugin/libhwprofile.so,arg=pattern will allow you to see the access pattern to devices, eg: gic_cpu @ 0xffffffc010040000 off:00000000, 8, 1, 8, 1 off:00000000, 4, 1, 4, 1 off:00000000, 2, 1, 2, 1 off:00000000, 1, 1, 1, 1 The source option: -plugin ./tests/plugin/libhwprofile.so,arg=source will track the virtual source address of the instruction making the access: pl011 @ 0xffffffc010031000 pc:ffffffc0104c785c, 1, 4, 0, 0 pc:ffffffc0104c7898, 1, 4, 0, 0 pc:ffffffc010512bcc, 2, 1867, 0, 0 You cannot mix source and pattern. Finally the match option allow you to limit the tracking to just the devices you care about.

Alex Bennée	c17a386b6a	plugins: move the more involved plugins to contrib We have an exploding complexity problem in the testing so lets just move the more involved plugins into contrib. tests/plugins still exist for the basic plugins that exercise the API. We restore the old pre-meson style Makefile for contrib as it also doubles as a guide for out-of-tree plugin builds. While we are at it add some examples to the documentation and a specific plugins build target.
