Subject: [PATCH 0/9] USB: serial: generic driver fixes and bulk buffer feature
Date: Wed, 17 Mar 2010 23:00:36 +0100 [thread overview]
Message-ID: <1268863245-17230-1-git-send-email-jhovold@gmail.com> (raw)
Hi,
Here are a few of fixes to the generic driver as well as a new feature that
lets drivers determine the size of the bulk buffers more easily. It turns out
that increasing the out-buffer sizes for cp210x and pl2303 have a significant
effect on throughput.
Thanks,
Johan
Johan Hovold (9):
USB: serial: allow drivers to define bulk buffer sizes
USB: cp210x: increase the bulk-out buffer size to 256 byte
USB: cp210x: increase bulk-in buffer size to 256 byte
USB: pl2303: increase the bulk-out buffer size to 256 byte
USB: pl2303: increase bulk-in buffer size to 256 byte
USB: serial: fix generic chars_in_buffer
USB: serial: fix missing locking on fifo in write callback
USB: serial: clear fifo on close
USB: serial: refactor generic close
