2024-07-05gdbstub: Move GdbCmdParseEntry into a new header fileGustavo Romero1-12/+13
Move GdbCmdParseEntry and its associated types into a separate header file to allow the use of GdbCmdParseEntry and other gdbstub command functions outside of gdbstub.c. Since GdbCmdParseEntry and get_param are now public, kdoc GdbCmdParseEntry and rename get_param to gdb_get_cmd_param. This commit also makes gdb_put_packet public since is used in gdbstub command handling.

2024-03-06{linux,bsd}-user: Introduce get_task_state()Ilya Leoshkevich1-2/+2
A CPU's TaskState is stored in the CPUState's void *opaque field, accessing which is somewhat awkward due to having to use a cast. Introduce a wrapper and use it everywhere.

2024-02-09gdbstub: Expose TARGET_SIGTRAP in a target-agnostic wayIlya Leoshkevich1-0/+5
The upcoming syscall catchpoint support needs to send SIGTRAP stop packets to GDB. Being able to compile this support only once for all targets is a good thing, and it requires hiding TARGET_SIGTRAP behind a function call.

2023-07-03gdbstub: Add support for info proc mappingsIlya Leoshkevich1-0/+137
Currently the GDB's generate-core-file command doesn't work well with qemu-user: the resulting dumps are huge [1] and at the same time incomplete (argv and envp are missing). The reason is that GDB has no access to proc mappings and therefore has to fall back to using heuristics for discovering them. This is, in turn, because qemu-user does not implement the Host I/O feature of the GDB Remote Serial Protocol. Implement vFile:{open,close,pread,readlink} and also qXfer:exec-file:read+. With that, generate-core-file begins to work on aarch64 and s390x.

2023-03-07gdbstub: move chunks of user code into own filesAlex Bennée1-0/+283
The process was pretty similar to the softmmu move except we take the time to split stuff between user.c and user-target.c to avoid as much target specific compilation as possible. We also start to make use of our shiny new header scheme so the user-only helpers can be included without the rest of the exec/gsbstub.h cruft. As before we split some functions into user and softmmu versions Reviewed-by: Fabiano Rosas <farosas@suse.de> Signed-off-by: Alex Bennée <alex.bennee@linaro.org> Message-Id: <20230302190846.2593720-12-alex.bennee@linaro.org> Message-Id: <20230303025805.625589-12-richard.henderson@linaro.org>
