I've checked drivers/char/tty_io.c :
/* * Change # of rows and columns (0 means unchanged/the size of fg_console) * [this is to be used together with some user program * like resize that changes the hardware videomode] */ int vc_resize(int currcons, unsigned int cols, unsigned int lines) { unsigned long old_origin, new_origin, new_scr_end, rlth, rrem, err = 0; unsigned int old_cols, old_rows, old_row_size, old_screen_size; unsigned int new_cols, new_rows, new_row_size, new_screen_size; unsigned short *newscreen;
WARN_CONSOLE_UNLOCKED();
if (!vc_cons_allocated(currcons)) return -ENXIO;
there is only place that returns ENXIO ... and if you take a look into vc_cons_allocated() :
int vc_cons_allocated(unsigned int i) { return (i < MAX_NR_CONSOLES && vc_cons[i].d); }
it might be either i exceeds MAX_NR_CONSOLES or vc_cons[i].d is 0.
btw, get TIOCGWINSZ, works fine and returns correct values as shown in strace. it is only SET part is failing ...
