This series replaces some of the call to exit in hardware used by Risc-V boards. Otherwise, the gdb connection can be abruptly disconnected resulting in the last gdb packet "Wxx" being not sent.
For the gdbstub modification, gdb_exit calls ensure that the "Wxx" packet is sent before exiting. However, some features (see net/vhost-vdpa.c: vhost_vdpa_cleanup for example) are expecting that a cleanup is being made before exiting. This, it's probably safer to follow the same logic here as well. Difference with v3: - Rebase on riscv-to-apply Clément Chigot (5): softmmu: add means to pass an exit code when requesting a shutdown softmmu: pass the main loop status to gdb "Wxx" packet hw/misc/sifive_test.c: replace exit calls with proper shutdown hw/char: riscv_htif: replace exit calls with proper shutdown gdbstub: replace exit calls with proper shutdown for softmmu gdbstub/gdbstub.c | 5 +++-- gdbstub/softmmu.c | 6 ++++++ gdbstub/user.c | 6 ++++++ hw/char/riscv_htif.c | 5 ++++- hw/misc/sifive_test.c | 9 +++++++-- include/gdbstub/syscalls.h | 9 +++++++++ include/sysemu/runstate.h | 2 ++ include/sysemu/sysemu.h | 2 +- softmmu/main.c | 2 +- softmmu/runstate.c | 16 +++++++++++++--- 10 files changed, 52 insertions(+), 10 deletions(-) -- 2.25.1
