USB: serial: add support for multiple read urbs

2011-11-15T18:46:13Z

Add support for multiple read urbs to generic read implementation. Use a static array of two read urbs for now which is enough to get a 50% throughput increase in one test setup. Signed-off-by: Johan Hovold Signed-off-by: Greg Kroah-Hartman

USB: serial: remove write_urb_busy field from usb_serial_port

USB: serial drivers need to use larger bulk-in buffers

2011-02-25T19:38:32Z

When a driver doesn't know how much data a device is going to send, the buffer size should be at least as big as the endpoint's maxpacket value. The serial drivers don't follow this rule; many of them request only 256-byte bulk-in buffers. As a result, they suffer overflow errors if a high-speed device wants to send a lot of data, because high-speed bulk endpoints are required to have a maxpacket size of 512. This patch (as1450) fixes the problem by using the driver's bulk_in_size value as a minimum, always allocating buffers no smaller than the endpoint's maxpacket size.

tty: remove filp from the USB tty ioctls

2011-02-17T19:59:14Z

We don't use it so we can trim it from here as we try and stamp the file object dependencies out of the serial code. Signed-off-by: Alan Cox Signed-off-by: Greg Kroah-Hartman

tiocmset: kill the file pointer argument

2011-02-17T19:52:43Z

Doing tiocmget was such fun we should do tiocmset as well for the same reasons Signed-off-by: Alan Cox Signed-off-by: Greg Kroah-Hartman

tiocmget: kill off the passing of the struct file

2011-02-17T19:47:33Z

We don't actually need this and it causes problems for internal use of this functionality. Currently there is a single use of the FILE * pointer. That is the serial core which uses it to check tty_hung_up_p. However if that is true then IO_ERROR is also already set so the check may be removed.

USB: serial: handle Data Carrier Detect changes

2011-01-23T02:53:26Z

Alan's commit 335f8514f200e63d689113d29cb7253a5c282967 introduced .carrier_raised function in several drivers. That also means tty_port_block_til_ready can now suspend the process trying to open the serial port when Carrier Detect is low and put it into tty_port.open_wait queue. We need to wake up the process when Carrier Detect goes high and trigger TTY hangup when CD goes low. Some of the devices do not report modem status line changes, or at least we don't understand the status message, so for those we remove .carrier_raised again.

tty: Make tiocgicount a handler

2010-10-22T17:20:04Z

Dan Rosenberg noted that various drivers return the struct with uncleared fields. Instead of spending forever trying to stomp all the drivers that get it wrong (and every new driver) do the job in one place. This first patch adds the needed operations and hooks them up, including the needed USB midlayer and serial core plumbing. Signed-off-by: Alan Cox Signed-off-by: Greg Kroah-Hartman

USB: drop tty argument from usb_serial_handle_sysrq_char()

2010-08-21T07:37:39Z

Since handle_sysrq() does not take tty as argument anymore we can drop it from usb_serial_handle_sysrq_char() as well. Acked-by: Alan Cox Acked-by: Jason Wessel Acked-by: Greg Kroah-Hartman Signed-off-by: Dmitry Torokhov
