2010-07-26dahdi: Move the 'owner' field from dahdi_span to dahdi_span_ops.Shaun Ruffell
One more thing that can be moved out of the per-span structure. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8986 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2010-07-26dahdi: Move the callbacks in dahdi_span into its own structure.Shaun Ruffell
Part of preparation for adding additional callbacks to allow board drivers to advertise and support gathering pre-echocan data from hardware echocans. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8985 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2010-07-26dahdi: Remove the 'pvt' member from dahdi_span.Shaun Ruffell
The vast majority of board drivers already keep the dahdi_span structure in a driver specific structure. The others were easily converted. This way board drivers can use the container_of macro to find what was previously pointed to by the "pvt" member of the span. One less thing to think about in the span structure. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8984 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2010-07-26wcte12xp, wctdm24xxp: spin_lock_bh -> spin_lock_irqsaveShaun Ruffell
Will add an option to allow calling the deferred processing callback directly in the interrupt handler. It appears there are some systems which still are unable to process their tasklets in a timely fashion, especially if they get pushed out to the ksoftirqd daemon. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8981 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2010-07-26wcte12xp, wctdm24xxp: Add shutdown handlers.Shaun Ruffell
Make the drivers a little more kexec friendly. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8979 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2010-05-25wctdm24xxp: Do not access memory after we free it.Shaun Ruffell
git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8689 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2010-05-17wctdm24xxp: dev_notice -> dev_infoShaun Ruffell
Modules that aren't installed should show at the same level as modules that are installed. It could be confusing if the console log level is set to 3 and only messages about which ports do not have any modules installed show up on the console. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8642 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2010-04-26wcte12xp, wctdm24xxp: Add vpm_firmware_version sysfs attribute.Shaun Ruffell
Currently only exported if CONFIG_VOICEBUS_SYSFS is defined in drivers/dahdi/voicebus.h. Reading from the 'vpm_firmware_version' attribute will poll the firmware on the VPMADT032 for it's current version. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8574 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2010-04-03wcte12xp, wtdm24xxp: Make sure the writes are retried.Shaun Ruffell
r8454 and r8460 introduced a change where writes are not retried when other module/framer commands are retried. This was an error and wasn't what was actually under test. This commit restores the behavior in wctdm24xxp and makes sure the vpm writes are retried in the wcte12xp. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8461 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2010-04-03wcte12xp, wctdm24xxp: Close a memory leak when processing VPM commands.Shaun Ruffell
Closes a memory leak when processing the VPM write commands introduced in r8454. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8460 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2010-04-03wcte12xp: Resend both framer and VPM commands when reads may have been lost.Shaun Ruffell
Latency conditions could cause the driver to misconfigure the VPM which would result in one way audio. DAHDI-572. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8454 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2010-03-25wctdm24xxp: Add an 'hx8' mode for buffer processing.Shaun Ruffell
The Hx8 series cards do not need any idle buffers and idle_buffers complicate processing when using the timing_cable. This change adds another mode of operation for the voicebus layer for the Hx8 cards that operates without the idle buffers. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8431 a0bf4364-ded3-4de4-8d8a-66a801d63aff

2010-03-02Revert commit 8096. Causes register problems on XHFC SPI interfaces.Matthew Fredrickson
git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8220 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2010-03-01wctdm24xxp: Mark the robust module parameter as DEBUG only.Shaun Ruffell
In testing this option didn't appear to function properly. Just mark it debug only so it's not part of the "official" interface in case there are some users of it out there that I'm not aware of. DAHDI-267. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8203 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2010-03-01wctdm24xxp, wcte12xp: Add optional module parameter to set the maximum latency.Shaun Ruffell
Setting the maximum latency can be useful if you have a system event that normally causes a latency increase, but you would rather have a break in the audio or frame slip, then let the latency grow to the current default maximum which is 25ms. DAHDI-278. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8198 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2010-03-01wcmtd24xxp, wcte12xp: Make vpmsupport module parameter read only.Shaun Ruffell
The vpmsupport module parameter (and a few other ones) do not do anything if they are changed after the driver is first loaded. Therefore, let's make these module parameters read only at runtime. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8188 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2010-03-01wctdm24xxp: Automatically fetch Hx8 firmware.Shaun Ruffell
Basically, fetch the Hx8 firmware like many of the other firmwares. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8171 a0bf4364-ded3-4de4-8d8a-66a801d63aff

2010-02-26wctdm24xxp: Do not assume CONFIG_HZ==100 for delays.Shaun Ruffell
git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8124 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2010-02-26wctdm24xxp: Add support for Hx8 series cards.Shaun Ruffell
The Hx8 series cards support BRI modules in addition to analog modules. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8123 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2010-02-26wctdm24xxp, wcte12xp: Updating the interface for the VPMADT032.Shaun Ruffell
This description needs to be filled in more. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8121 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2010-02-25wctdm24xxp: Partially unroll the TDM data extraction / insertion.Shaun Ruffell
Saves about 10us each interrupt on 3.06 GHz Xeon. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8097 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2010-02-25wctdm24xxp: Only use the first three EFRAMES for module commands.Shaun Ruffell
On a 2.6.32.7 debug kernel with a TDM2400, this can save up to 30ms every second of processing time without any appreciable impact on runtime performance since most of the commands to the modules during normal operation are reads, and therefore only one would be in each SFRAME anyway. The impact of this change is less for TDM410 and TDM800 since they already limit the number of modules that they look for queued commands for. There is still more room for optimizing module command handling. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8096 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2010-02-25wctdm24xxp, wcte12xp: Buffer handling improvements.Shaun Ruffell
This patch moves the majority of the buffer processing for the voicebus based cards out of the interrupt handler and into a tasklet. When multiple cards are running on the same CPU, and there was a latency condition that would cause them to get behind, this now allows the tasklet to limit how many buffers are processed on each card before giving the other card a chance to start working on it's backlog. Additionally, when the card detects a hard under run, instead of trying to fix it up in the handling routine, it will now reschedule a work item that will completely reset the descriptor rings. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8095 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2010-02-25wctdm24xxp: Provide option to initialize boards in parallel on kernels > 2.6.30Shaun Ruffell
The 2.6.30 kernel provides support for asynchronous initialization. If running on a kernel that supports this feature, let's add an option to use it in order to speed up driver load times. Keep it off by default. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8094 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2010-02-10wctdm24xxp: make sure we show which card is displaying the message.Shaun Ruffell
NOTE: This change has formatting problems that I'll fix in a later commit, I do not want to cause myself too much merge pain right here. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8024 a0bf4364-ded3-4de4-8d8a-66a801d63aff

2010-02-08wctdm24xxp, wcte12xp: Abort the search for modules if killed.Shaun Ruffell
If the user kills the modprobe process that is initializing the modules, exit as soon as possible and do not look for any other modules. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8007 a0bf4364-ded3-4de4-8d8a-66a801d63aff

2010-02-03wctdm24xxp, voicebus: Move sysfs handling from voicebus to wctdm24xxp.Shaun Ruffell
The drv_data attached to the pci_dev is no longer the 'struct voicebus' pointer, but is instead the 'struct wctdm' (or 'struct t1'), so the clients need to manage the sysfs files themselves. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@7983 a0bf4364-ded3-4de4-8d8a-66a801d63aff

2010-01-08voicebus: Remove framesize, buffer_cache, and cache_line members from struct.Shaun Ruffell
Framesize is the same on all the clients, so it can be removed from the 'struct voicebus' (and changed back again if needed). Since the framesize is the same, each board doesn't need it's own buffer_cache, and cache_line is only used during startup and can be read directly from pci configuration space, so we don't need to keep it around in our context. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@7779 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2010-01-08voicebus: Make 'struct voicebus' embeddable by the client driver strutures.Shaun Ruffell
In addition to making 'struct voicebus' embeddable, also add an 'voicebus_operations' structure. This was done so that a) remove the "context" pointer from struct voicebus, and also to show that handle_recieve/transmit are to be managed together. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@7778 a0bf4364-ded3-4de4-8d8a-66a801d63aff

2009-11-12voicebus: Fix race when enabling/disabling hardware echocan.Shaun Ruffell
This closes a race condition where it was possible for the driver to believe it has enabled the VPMADT032 when in fact, it really has not. This fixes a regression introduced in dahdi-linux 2.2.0. (issue #15724) git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@7565 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2009-11-07voicebus: Add optional sysfs entry for reading a boards current latency.Shaun Ruffell
This is off by default since it hasn't been tested on a full range of kernels, but can be useful for quickly seeing differences for latencies on different cards installed in the system. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@7522 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2009-11-07voicebus, wctdm24xxp, wcte12xp: Move a print out of the interrupt handler.Shaun Ruffell
This can be handled just as well in process context and printing to a serial console from the interrupt handler has the potential to cause long latencies. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@7521 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2009-11-07wctdm24xxp: Lock latency when loadingShaun Ruffell
