Subject: [PATCH v6 0/9] TCG plugins new inline operations
Date: Thu, 2 May 2024 14:15:13 -0700 [thread overview]
Message-ID: <20240502211522.346467-1-pierrick.bouvier@linaro.org> (raw)
This series implement two new operations for plugins:
- Store inline allows to write a specific value to a scoreboard.
- Conditional callback executes a callback only when a given condition is true.
The condition is evaluated inline.
It's possible to mix various inline operations (add, store) with conditional
callbacks, allowing efficient "trap" based counters.
It builds on top of new scoreboard API, introduced in the previous series.
v2
--
- fixed issue with udata not being passed to conditional callback
- added specific test for this in tests/plugin/inline.c (udata was NULL before).
v3
--
- rebased on top of "plugins: Rewrite plugin code generation":
20240316015720.3661236-1-richard.henderson@linaro.org
- single pass code generation
- small cleanups for code generation
v4
--
- remove op field from qemu_plugin_inline_cb
- use tcg_constant_i64 to load immediate value to store
v5
--
- rebase on top of master now that Richard's series was merged
v6
--
- more elaborated commit messages
