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>
2019-10-28plugin: expand the plugin_init function to include an info blockAlex Bennée
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.
