2018-03-27gdbstub: send a termination packet instead of crashing gdbKONRAD Frederic1-0/+2
Since the commit: commit 4486e89c219c0d1b9bd8dfa0b1dd5b0d51ff2268 Author: Stefan Hajnoczi <stefanha@redhat.com> Date: Wed Mar 7 14:42:05 2018 +0000 vl: introduce vm_shutdown() GDB crashes when qemu exits (at least on sparc-softmmu): Remote communication error. Target disconnected.: Connection reset by peer. Quitting: putpkt: write failed: Broken pipe. So send a packet to exit GDB before we exit QEMU: [Inferior 1 (Thread 0) exited normally] Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Reviewed-by: Stefan Hajnoczi <stefanha@redhat.com> Signed-off-by: KONRAD Frederic <frederic.konrad@adacore.com> Message-id: 1521538773-30802-1-git-send-email-frederic.konrad@adacore.com Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2017-07-14gdbstub: rename cpu_index -> cpu_gdb_indexAlex Bennée1-9/+0
This is to make it clear the index is purely a gdbstub function and should not be confused with the value of cpu->cpu_index. At the same time we move the function from the header to gdbstub itself which will help with later changes.

2015-07-09gdbstub: Change gdbserver_fork() to accept cpu instead of envPeter Crosthwaite1-1/+1
All callsites to this function navigate the cpu->env_ptr only for the function to take the env ptr back to the original cpu ptr. Change the function to just pass in the CPU pointer instead. Removes a core code usage of ENV_GET_CPU() (in gdbstub.c).

2015-06-19semihosting: create SemihostingConfig structure and semihost.hLeon Alrae1-6/+0
Remove semihosting_enabled and semihosting_target and replace them with SemihostingConfig structure containing equivalent fields. The structure is defined in vl.c where it is actually set. Also introduce separate header file include/exec/semihost.h allowing to access semihosting config related stuff from target specific semihosting code.

2014-12-11Add the "-semihosting-config" option.Liviu Ionescu1-0/+6
The usual semihosting behaviour is to process the system calls locally and return; unfortuantelly the initial implementation dinamically changed the target to GDB during debug sessions, which, for the usual arm-none-eabi-gdb, is not implemented. The result was that during debug sessions the semihosting calls were discarded. This patch adds a configuration variable and an option to set it on the command line: -semihosting-config [enable=on|off,]target=native|gdb|auto This option enables semihosting and defines where the semihosting calls will be addressed, to QEMU ('native') or to GDB ('gdb'). The default is auto, which means 'gdb' during debug sessions and 'native' otherwise.

This avoids polluting the global namespace with a non-prefixed macro and makes it obvious in the call sites that we return. Semi-automatic conversion using, e.g., sed -i 's/GET_REGL(/return gdb_get_regl(mem_buf, /g' target-*/gdbstub.c followed by manual tweaking for sparc's GET_REGA() and Coding Style.

2013-07-22configure: Make NPTL non-optionalPeter Maydell1-1/+1
Now all linux-user targets support building with NPTL, we can make it mandatory. This is a good idea because: * NPTL is no longer new and experimental; it is completely standard * in practice, linux-user without NPTL is nearly useless for binaries built against non-ancient glibc * it allows us to delete the rather untested code for handling the non-NPTL configuration Note that this patch leaves the CONFIG_USE_NPTL ifdefs in the bsd-user codebase alone. This makes no change for bsd-user, since our configure test for NPTL had a "#include <linux/futex.h>" which means bsd-user would never have been compiled with CONFIG_USE_NPTL defined, and it still is not.
