Subject: [PATCH v7 07/10] btrace, gdbserver: Add ptwrite to btrace_config_pt.
Date: Fri, 21 Oct 2022 13:59:44 +0200 [thread overview]
Message-ID: <20221021115947.359223-8-felix.willgerodt@intel.com> (raw)
In-Reply-To: <20221021115947.359223-1-felix.willgerodt@intel.com>
This enables gdb and gdbserver to communicate about ptwrite support. If
ptwrite support would be enabled unconditionally, GDBs with older libipt
versions would break.
