However, it doesn't return a CN_* code. So checking its return value against CN_DEAD (which is 0) is incorrect, and in this case, a success becomes a failure. The consequence was unimportant, because the caller (drm_fb_helper.c) would only log an error message in this case. The console would still work. Approved by: nwhitehorn r270705: vt(4): Add cngrab() and cnungrab() callbacks They are used when a panic occurs or when entering a DDB session for instance. cngrab() forces a vt-switch to the console window, no matter if the original window is another terminal or an X session. However, cnungrab() doesn't vt-switch back to the original window currently. r270706: drm: Don't "taskqueue" vt-switch if under DDB/panic situation If DDB is active, we can't use a taskqueue thread to switch away from the X window, because this thread can't run. Reviewed by: ray@ Approved by: ray@ r271180: vt_vga: vd_setpixel_t and vd_drawrect_t are noop in text mode r271250: vt(4): Change the terminal and buffer sizes, even without a font This fixes a bug where scroll lock would not work for tty #0 when using vt_vga's textmode. The reason was that this window is created with a static 256x100 buffer, larger than the real size of 80x25. Now, in vt_change_font() and vt_compute_drawable_area(), we still perform operations even of the window has no font loaded (this is the case in textmode here vw->vw_font == NULL). One of these operation resizes the buffer accordingly. In vt_compute_drawable_area(), we take the terminal size as is (ie. 80x25) for the drawable area. The font argument to vt_set_border() is removed (it was never used) and the code now uses the computed drawable area instead of re-doing its own calculation.
