2020-08-21meson: link emulators without Makefile.targetPaolo Bonzini
The binaries move to the root directory, e.g. qemu-system-i386 or qemu-arm. This requires changes to qtests, CI, etc. Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2020-08-21meson: pluginsPaolo Bonzini
For now link arguments end up in Makefile.target, they will move to the right place soon. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2020-05-15qemu/qemu-plugin: Make qemu_plugin_hwaddr_is_io() hwaddr argument constPhilippe Mathieu-Daudé
Rename qemu_plugin_hwaddr_is_io() address argument 'haddr' similarly to qemu_plugin_hwaddr_device_offset(), and make it const.

2020-03-17lockable: add QemuRecMutex supportStefan Hajnoczi
The polymorphic locking macros don't support QemuRecMutex yet. Add it so that lock guards can be used with QemuRecMutex. Convert TCG plugins functions that benefit from these macros. Manual qemu_rec_mutex_lock/unlock() callers are left unmodified in cases where clarity would not improve by switching to the macros.

2020-01-15plugins: Include trace/mem.h in api.cRichard Henderson
Code movement in an upcoming patch will show that this file was implicitly depending on trace/mem.h being included beforehand.

2019-11-12tcg plugins: expose an API version conceptAlex Bennée
This is a very simple versioning API which allows the plugin infrastructure to check the API a plugin was built against. We also expose a min/cur API version to the plugin via the info block in case it wants to avoid using old deprecated APIs in the future.

2019-10-28plugin: add qemu_plugin_outs helperAlex Bennée
Having the plugins grab stdout and spew stuff there is a bit ugly and certainly makes the tests look ugly. Provide a hook back into QEMU which can be redirected as needed. Signed-off-by: Alex Bennée <alex.bennee@linaro.org> Reviewed-by: Aaron Lindsay <aaron@os.amperecomputing.com>
2019-10-28plugin: add qemu_plugin_insn_disas helperAlex Bennée
Give the plugins access to the QEMU dissasembler so they don't have to re-invent the wheel. We generate a warning when there are spare bytes in the decode buffer. This is usually due to the front end loading in more bytes than decoded. Signed-off-by: Alex Bennée <alex.bennee@linaro.org> Reviewed-by: Richard Henderson <richard.henderson@linaro.org>

This provides a limited amount of info to plugins about the guest system that will allow them to make some additional decisions on setup. Signed-off-by: Alex Bennée <alex.bennee@linaro.org>

2019-10-28plugins: implement helpers for resolving hwaddrAlex Bennée
We need to keep a local per-cpu copy of the data as other threads may be running. Currently we can provide insight as to if the access was IO or not and give the offset into a given device (usually the main RAMBlock). We store enough information to get details such as the MemoryRegion which might be useful in later expansions to the API.
