Subject: [PATCH v4 0/5] Risc-V/gdb: replace exit calls with proper shutdown
Date: Tue, 3 Oct 2023 09:14:22 +0200 [thread overview]
Message-ID: <20231003071427.188697-1-chigot@adacore.com> (raw)
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
