Subject: [PATCH 0/5] TriCore fixes and gdbstub
Date: Mon, 30 Sep 2019 14:46:38 +0200 [thread overview]
Message-ID: <20190930124643.179695-1-kbastian@mail.uni-paderborn.de> (raw)
Hi,
this series fixes a few TriCore problems:
- Segfault due to non initialized ctx->env ptr (see
https://lists.gnu.org/archive/html/qemu-devel/2019-09/msg03527.html)
I fixed this by properly detangling any reference of the env pointer in the
translate functions. (as suggested by Peter Maydell)
- Unimplemented tricore_cpu_get_phys_page_debug() which lead to a temporary fix
(see b190f477e29c7cd03a8fee49c96d27f160e3f5b0)
The last patch implements a gdbstub for TriCore.
Cheers,
Bastian
