* qemu/qemu-plugin: Make qemu_plugin_hwaddr_is_io() hwaddr argument constPhilippe Mathieu-Daudé2020-05-151-2/+2
| | | | | | | | | | | | Rename qemu_plugin_hwaddr_is_io() address argument 'haddr' similarly to qemu_plugin_hwaddr_device_offset(), and make it const.

* plugins: Include trace/mem.h in api.cRichard Henderson2020-01-161-0/+1
| | | | | | | | | | Code movement in an upcoming patch will show that this file was implicitly depending on trace/mem.h being included beforehand.

* plugin: add qemu_plugin_outs helperAlex Bennée2019-10-281-0/+8
| | | | | | | | | 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>
* plugin: add qemu_plugin_insn_disas helperAlex Bennée2019-10-281-1/+8
| | | | | | | | | | 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>
* plugins: implement helpers for resolving hwaddrAlex Bennée2019-10-281-0/+49
| | | | | | | | | | | 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.
