* plugins: expand kernel-doc for qemu_info_tAlex Bennée2021-03-171-7/+15
| | | | | | | | It seems kernel-doc struggles a bit with typedef structs but with enough encouragement we can get something out of it. Signed-off-by: Alex Bennée <alex.bennee@linaro.org> Message-Id: <20210312172821.31647-5-alex.bennee@linaro.org>
* plugins: Expose physical addresses instead of device offsetsAaron Lindsay2021-03-171-7/+25
| | | | | | | | | | | | This allows plugins to query for full virtual-to-physical address translation for a given `qemu_plugin_hwaddr` and stops exposing the offset within the device itself. As this change breaks the API, QEMU_PLUGIN_VERSION is incremented.

| | | | | | | | | | | | Since commit efc6c07 ("configure: Add a test for the minimum compiler version"), QEMU explicitely depends on GCC >= 4.8.

* tcg plugins: expose an API version conceptAlex Bennée2019-11-121-0/+19
| | | | | | | | | | | | 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.

* plugin: add qemu_plugin_outs helperAlex Bennée2019-10-281-0/+6
| | | | | | | | | 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 Bennée2019-10-281-0/+9
| | | | | | | | | | 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>
* plugin: expand the plugin_init function to include an info blockAlex Bennée2019-10-281-2/+24
| | | | | | | | 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>
* plugins: implement helpers for resolving hwaddrAlex Bennée2019-10-281-0/+8
| | | | | | | | | | | 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.
