This continues the effort\nto decouple the VT100 emulation from the chardev backend, making the\nVT100 layer self-contained and reusable.\n\nvc_chr_write() becomes a thin wrapper that extracts the QemuVT100 from\nthe chardev and delegates to vt100_input().\n\nReviewed-by: Philippe Mathieu-Daudé <philmd@linaro.org>\nSigned-off-by: Marc-André Lureau <marcandre.lureau@redhat.com>\n---\n ui/console-vc.c | 34 ++++++++++++++++++++--------------\n 1 file changed, 20 insertions(+), 14 deletions(-)", "diff": "diff --git a/ui/console-vc.c b/ui/console-vc.c\nindex 5cfb3dfcf72..15600128380 100644\n--- a/ui/console-vc.c\n+++ b/ui/console-vc.c\n@@ -1057,29 +1057,35 @@ static void vt100_putchar(QemuVT100 *vt, int ch)\n DECLARE_INSTANCE_CHECKER(VCChardev, VC_CHARDEV,\n TYPE_CHARDEV_VC)\n \n-static int vc_chr_write(Chardev *chr, const uint8_t *buf, int len)\n+static size_t vt100_input(QemuVT100 *vt, const uint8_t *buf, size_t len)\n {\n- VCChardev *drv = VC_CHARDEV(chr);\n- QemuTextConsole *s = drv->console;\n int i;\n \n- s->vt.update_x0 = s->vt.width * FONT_WIDTH;\n- s->vt.update_y0 = s->vt.height * FONT_HEIGHT;\n- s->vt.update_x1 = 0;\n- s->vt.update_y1 = 0;\n- vt100_show_cursor(&s->vt, 0);\n+ vt->update_x0 = vt->width * FONT_WIDTH;\n+ vt->update_y0 = vt->height * FONT_HEIGHT;\n+ vt->update_x1 = 0;\n+ vt->update_y1 = 0;\n+ vt100_show_cursor(vt, 0);\n for(i = 0; i < len; i++) {\n- vt100_putchar(&s->vt, buf[i]);\n+ vt100_putchar(vt, buf[i]);\n }\n- vt100_show_cursor(&s->vt, 1);\n- if (s->vt.update_x0 < s->vt.update_x1) {\n- vt100_image_update(&s->vt, s->vt.update_x0, s->vt.update_y0,\n- s->vt.update_x1 - s->vt.update_x0,\n- s->vt.update_y1 - s->vt.update_y0);\n+ vt100_show_cursor(vt, 1);\n+ if (vt->update_x0 < vt->update_x1) {\n+ vt100_image_update(vt, vt->update_x0, vt->update_y0,\n+ vt->update_x1 - vt->update_x0,\n+ vt->update_y1 - vt->update_y0);\n }\n return len;\n }\n \n+static int vc_chr_write(Chardev *chr, const uint8_t *buf, int len)\n+{\n+ VCChardev *drv = VC_CHARDEV(chr);\n+ QemuTextConsole *s = drv->console;\n+\n+ return vt100_input(&s->vt, buf, len);\n+}\n+\n void vt100_update_cursor(void)\n {\n QemuVT100 *vt;\n", "prefixes": [ "v2", "26/67" ] }
