2016-10-24char: remove explicit_be_open from CharDriverStateMarc-André Lureau1-0/+1
It's only used in qmp_chardev_add(), so use a create() argument instead. Also switched to typedef functions for CharDriverParse/CharDriverCreate.

2016-10-24char: rename chr_close/chr_freeMarc-André Lureau1-2/+2
The function is used to free the backend opaque pointer, let's name it accordingly. Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Message-Id: <20161022095318.17775-23-marcandre.lureau@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2016-02-04backends: Clean up includesPeter Maydell1-0/+1
Clean up includes so that osdep.h is included first and headers which it implies are not included manually. This commit was created with scripts/clean-includes. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Message-id: 1454089805-5470-5-git-send-email-peter.maydell@linaro.org

2015-10-14qemu-char: add create to register_char_driverPaolo Bonzini1-1/+2
Having creation as a member of the CharDriver struct removes the need to export functions for qemu-char.c's usage. After the conversion, chardev backends implemented outside qemu-char.c will not need a stub creation function anymore. Ultimately all drivers will be converted. For now, support the case where cd->create == NULL. Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2015-09-16qemu-char: Use g_new() & friends where that makes obvious senseMarkus Armbruster1-2/+2
g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer, for two reasons. One, it catches multiplication overflowing size_t. Two, it returns T * rather than void *, which lets the compiler catch more type errors. This commit only touches allocations with size arguments of the form sizeof(T). Same Coccinelle semantic patch as in commit b45c03f.

2014-09-16qemu-char: Rename register_char_driver_qapi() to register_char_driver()Peter Maydell1-1/+1
Now we have removed the legacy register_char_driver() we can rename register_char_driver_qapi() to the more obvious and shorter name. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Message-id: 1409653457-27863-6-git-send-email-peter.maydell@linaro.org
2014-08-06backends: Introduce chr-testdevPaolo Bonzini1-0/+131
From: Paolo Bonzini <pbonzini@redhat.com> chr-testdev enables a virtio serial channel to be used for guest initiated qemu exits. hw/misc/debugexit already enables guest initiated qemu exits, but only for PC targets. chr-testdev supports any virtio-capable target. kvm-unit-tests/arm is already making use of this backend. Currently there is a single command implemented, "q". It takes a (prefix) argument for the exit code, thus an exit is implemented by writing, e.g. "1q", to the virtio-serial port. It can be used as: $QEMU ... \ -device virtio-serial-device \ -device virtserialport,chardev=ctd -chardev testdev,id=ctd or, use: $QEMU ... \ -device virtio-serial-device \ -device virtconsole,chardev=ctd -chardev testdev,id=ctd to bind it to virtio-serial port0.
