http://perforce.freebsd.org/chv.cgi?CH=37471 Change 37471 by marcel@marcel_nfs on 2003/09/03 19:58:22 o Display flow control capabilities of the UART. o Display the line settings (baudrate, parity, databits and stopbits) for system devices. The SAB 82532 driver (with uncommitted support for HW flow control) now announces itself as: : uart0: <SAB 82532 v3.2, channel A> on puc0 uart0: RTS iflow, CTS oflow uart0: console (9600,n,8,1) uart1: <SAB 82532 v3.2, channel B> on puc0 uart1: RTS iflow, CTS oflow : Affected files ... .. //depot/projects/uart/dev/uart/uart_core.c#26 edit Differences ... ==== //depot/projects/uart/dev/uart/uart_core.c#26 (text+ko) ==== @@ -345,21 +345,18 @@ if (error) goto fail; - if (sc->sc_sysdev != NULL) { - switch (sc->sc_sysdev->type) { - case UART_DEV_CONSOLE: - device_printf(dev, "console\n"); - break; - case UART_DEV_DBGPORT: - device_printf(dev, "debug port\n"); - break; - case UART_DEV_KEYBOARD: - device_printf(dev, "keyboard\n"); - break; - default: - device_printf(dev, "unknown system device\n"); - break; + if (sc->sc_hwiflow || sc->sc_hwoflow) { + sep = ""; + device_print_prettyname(dev); + if (sc->sc_hwiflow) { + printf("%sRTS iflow", sep); + sep = ", "; + } + if (sc->sc_hwoflow) { + printf("%sCTS oflow", sep); + sep = ", "; } + printf("\n"); } if (bootverbose && (sc->sc_fastintr || sc->sc_polled)) { @@ -376,6 +373,26 @@ printf("\n"); } + if (sc->sc_sysdev != NULL) { + switch (sc->sc_sysdev->type) { + case UART_DEV_CONSOLE: + device_printf(dev, "console"); + break; + case UART_DEV_DBGPORT: + device_printf(dev, "debug port"); + break; + case UART_DEV_KEYBOARD: + device_printf(dev, "keyboard"); + break; + default: + device_printf(dev, "unknown system device"); + break; + } + printf(" (%d,%c,%d,%d)\n", sc->sc_sysdev->baudrate, + "noems"[sc->sc_sysdev->parity], sc->sc_sysdev->databits, + sc->sc_sysdev->stopbits); + } + error = (sc->sc_sysdev != NULL && sc->sc_sysdev->attach != NULL) ?
