From bd88c780e6a17188f7fd676f3a056e5db21500e0 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Alex=20Benn=C3=A9e?= Date: Wed, 12 Jul 2017 11:52:15 +0100 Subject: qom/cpu: remove host_tid field MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This was only used by the gdbstub and even then was only being set for subsequent threads. Rather the continue duplicating the number just make the gdbstub get the information from TaskState structure. Now the tid is correctly reported for all threads the bug I was seeing with "vCont;C04:0;c" packets is fixed as the correct tid is reported to gdb. I moved cpu_gdb_index into the gdbstub to facilitate easy access to the TaskState which is used elsewhere in gdbstub. To prevent BSD failing to build I've included ts_tid into its TaskStruct but not populated it - which was the same state as the old cpu->host_tid. I'll leave it up to the BSD maintainers to actually populate this properly if they want a working gdbstub with user-threads.
