Add a tty code to indicate a resize frame. The body contains two big endian 16-bit integers rows and columns. --- Changelog: v3: - split console_reset indentation fix into its own patch v2: - Use packed struct and named event type codes for resize frames - Trigger initial resize event in console_reset() instead of console_init(), skip when chardev reports no size - Reset event_pending after resize event Requires the following pre-req: [PATCH v7 00/12] virtio-console: notify about the terminal size (https://lore.kernel.org/qemu-devel/20260609-console-resize-v7-0-0c550fdcec15@gmail.com/) Testing: - Tested on QEMU: commit 38879a667f with the following patches applied: [PATCH v7 00/12] virtio-console: notify about the terminal size - Tested on linux-next (commit c1f49dea2b8f) with the following patches applied: [PATCH 0/2] s390/sclp: Resize for sclp-vt220 console Maximilian Immanuel Brandtner (2): s390x/sclpconsole: fix indentation for console_reset s390x/sclpconsole: implement resizing for vt220 consoles hw/char/sclpconsole.c | 92 +++++++++++++++++++++++++++++++++++++------ 1 file changed, 80 insertions(+), 12 deletions(-) -- 2.54.0
