OpenBSD/sgi on octane2 - cpu1デバッグ用のcom1向け簡易printfの実装 その２

printf関係ないけど、要らんコードをちょっと捨てた。

#define	COM_NPORTS	8
#define COMBBUF_SIZE 2048
int combfreq = 22000000 / 3;
int combrate = (B9600);
bus_addr_t combaddr = 0x500000 + IOC3_UARTB_BASE;
bus_space_tag_t combiot = &sys_config.console_io;
bus_space_handle_t combioh;
char combbuf[COMBBUF_SIZE] = {0};

void
cominit(bus_space_tag_t iot, bus_space_handle_t ioh, int rate, int frequency);

static void
combinit(void)
{
	if (bus_space_map(combiot, combaddr, COM_NPORTS, 0, &combioh))
		panic("comcninit: mapping failed");

	cominit(combiot, combioh, combrate, combfreq);
}

static void
combputc(int c)
{
	com_common_putc(combiot, combioh, c);
}

static int
combprintf(const char *fmt, ...)
{
	int i;
	va_list ap;

	va_start(ap, fmt);
	vsnprintf(combbuf, COMBBUF_SIZE, fmt, ap);
	va_end(ap);
	for(i = 0; i < COMBBUF_SIZE; i++)
		if(combbuf[i] == '\0')
			break;
		else
			combputc(combbuf[i]);
	
	return 0;
}
