| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As reported by Vipul Gandhi, the current serial_match_port() doesn't work for tty-devices using dynamic major number allocation. Fix it. It oopses if you suspend a serial port with _dynamic_ major number. ATM, I think, there's only the drivers/serial/jsm/jsm_driver.c driver, that does it in-tree.

* atmel_serial: filter out FP during baud rate detectionHaavard Skinnemoen2008-06-06
| | | | | | | | | | | | | | | | I made a change to u-boot that used the FP (Fractional Part) field of BRGR to achieve more accurate baud rate generation. Unfortunately, the atmel_serial driver looks at the whole BRGR register when trying to detect the baud rate that the port is currently running at, so setting FP to a nonzero value breaks the baud rate detection. I'll sit on the u-boot patch for a while longer, but this is clearly a bug in the atmel_serial driver which should be fixed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some drivers are using too generic "serial" name for driver_name, this might cause issues, like this: Freescale QUICC Engine UART device driver proc_dir_entry 'serial' already registered Call Trace: [cf82de50] [c0007f7c] show_stack+0x4c/0x1ac (unreliable) [cf82de90] [c00b03fc] proc_register+0xfc/0x1ac [cf82dec0] [c00b05c8] create_proc_entry+0x60/0xac [cf82dee0] [c00b23dc] proc_tty_register_driver+0x60/0x98 [cf82def0] [c016dbd8] tty_register_driver+0x1b4/0x228 [cf82df20] [c0184d70] uart_register_driver+0x144/0x194 [cf82df40] [c030a378] ucc_uart_init+0x2c/0x94 [cf82df50] [c02f21a0] kernel_init+0x98/0x27c [cf82dff0] [c000fa74] kernel_thread+0x44/0x60 ^^ The board is using ucc_uart.c and 8250.c, both registered as "serial".

* Fix uart_set_ldisc() function typeLinus Torvalds2008-06-04
| | | | | | | | | | | | | | | Commit 64e9159f5d2c4edf5fa6425031e556f8fddaf7e6 ("serial_core: uart_set_ldisc infrastructure") introduced the ability for low-level serial drivers to be informed when the tty ldisc changes. However, the actual tty-layer function that does this callback for serial devices was declared with the wrong type, having a spurious and unused 'ldisc' argument. This fixed the resulting compiler warning by just removing it. Acked-by: Blithering Idiot <alan@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* serial_core: uart_set_ldisc infrastructureAlan Cox2008-06-03
| | | | | | | | | | | | | | | | | The tty layer provides a callback that is used when the line discipline is changed. Some hardware uses this to configure hardware specific features such as IrDA mode on serial ports. Unfortunately the serial layer does not provide this feature or pass it down to drivers. Blackfin used to hack around this by rewriting the tty ops, but those are now properly shared and const so the hack fails. Instead provide the proper operations. This change plus a follow up from the Blackfin guys is needed to avoid blackfin losing features in this release.

* | serial: access after NULL check in uart_flush_buffer()Tetsuo Handa2008-05-08
|/ | | | | | | | | | | | | | | | | | | | | | | | | | I noticed that static void uart_flush_buffer(struct tty_struct *tty) { struct uart_state *state = tty->driver_data; struct uart_port *port = state->port; unsigned long flags; /* * This means you called this function _after_ the port was * closed. No cookie for you. */ if (!state || !state->info) { WARN_ON(1); return; } is too late for checking state != NULL.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mpc52xx_uart_int and __uart_put_char both try to acquire the port->lock. Therefore the function sequence of: mpc52xx_uart_int--> ...-->flush_to_ldisc-->...-->__uart_put_char can potentially trigger a deadlock. To avoid this deadlock a fix similar to that found in the 8250.c serial driver is applied. The deadlock is avoided by releasing the lock before pushing a buffer and reacquiring it when completed.
