2011-01-03"struct pci_device_id[]" -> "DEFINE_PCI_DEVICE_TABLE"Shaun Ruffell
2.6.25 added the DEFINE_PCI_DEVICE_TABLE macro to make sure that the pci_device_id tables are put into the correct section in the binary. Convert all the places where the tables were defined to use them. This is linux-2.6 commit where the change went in along with the rationale: 90a1ba0c5e39eeea278f263c28ae02166c5911c8 Signed-off-by: Shaun Ruffell <sruffell@digium.com> Acked-by: Kinsey Moore <kmoore@digium.com> git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@9584 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2010-12-15wctc4xxp: Make the "mode" module parameter read-only in sysfs.Shaun Ruffell

2010-11-04Remove mutex emulationShaun Ruffell
Using semaphores as mutexes was removed from the kernel in 4882720b267b. Just use straight semaphores now. 'DECLARE_MUTEX()' -> 'DEFINE_SEMAPHORE()' and 'init_MUTEX()' -> 'sema_init()'.

2010-10-20wctc4xxp: 'WARN_ON(1)' -> 'dev_info(...' on channel creation failure.Shaun Ruffell
If the DSP ever finds it's way into a bad state it can be possible for a timeslot to get 'wedged'. All attempts to create a channel in a wedged timeslot will fail and the WARN_ON macro can quickly fill the logs. This change adds some more debugging information (which timeslot is wedged) along with the result code from the DSP and puts it all behind a printk_ratelimit.

2010-07-28wctc4xxp: Do not ACK response packets without a corresponding request.Shaun Ruffell
Closes a small window of opportunity where system conditions prevent the driver from servicing it's receive ring within the timeout period of a request, and then in the middle of retrying the request (after the request was already removed from the "waiting_for_response" list) the driver process the response, it's possible for the driver to ACK the response without ever pairing it up with the original request. The result being that the DTE will then ignore our attempts to retry the original request. DAHDI-430. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@9035 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2010-07-28wctc4xxp: Allow read to return more than one packet of data.Shaun Ruffell
As of this writing codec_dahdi (Asterisk module) will not call 'read' on a transcoder channel more often than it calls 'write'. When a translation path is setup that will transcode from g723 to g729, write is called every 30ms and each 'read' returns only 20ms of data. The end result is audio that slowly becomes increasing delayed. Since codec_dahdi calls the system read function with a buffer large enough to hold more than one packet this can prevents packets from backing up on the channel. DAHDI-582 git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@9034 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2010-06-29wctc4xxp: Fix "operation on may be undefined" warning.Shaun Ruffell
gcc 4.5.0 was generating a warning on the changed line, and the discussion at http://gcc.gnu.org/ml/gcc/2004-10/msg00024.html explains why. Essentially, the only thing guaranteed with the preincrement operator is that the value will be incremented before the assignment. It's undefined where in the sequence the mask will be applied. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8831 a0bf4364-ded3-4de4-8d8a-66a801d63aff

2009-03-23Do not handle duplicate reponses.Shaun Ruffell
It is possible for system activity to prevent the wctc4xxp driver from responding the the firmware on the TC400M for a period of time. If this occurs, the TC400M will resend a response to a command that we sent. This duplicate reponse will then sometimes confuse the driver. Normally this would manifest as an attempt to connect the same channel together in a transcoding session. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@6224 a0bf4364-ded3-4de4-8d8a-66a801d63aff
