From 92e28c03d6162d55b40f7052962067c021c90e7d Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Alex=20Benn=C3=A9e?= Date: Wed, 5 Jan 2022 13:49:57 +0000 Subject: monitor: move x-query-profile into accel/tcg to fix build MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit As --enable-profiler isn't defended in CI we missed this breakage. Move the qmp handler into accel/tcg so we have access to the helpers we need. While we are at it ensure we gate the feature on CONFIG_TCG. Signed-off-by: Alex Bennée Suggested-by: Daniel P.
