2010-09-23wct4xxp: Add debug option to log detected RBS bit changes.Shaun Ruffell
Normally you can see RBS bit states in dahdi_tool, but you might also want them logged to dmesg for troubleshooting. (issue #18025) Signed-off-by: Shaun Ruffell <sruffell@digium.com> Acked-by: Russ Meyerriecks <rmeyerriecks@digium.com> git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@9399 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2010-09-21wcte12xp, wctdm24xxp: Do not rely on polling main memory.Shaun Ruffell
The voicebus library by default configures the PCI interface to poll the descriptor ring for available buffers. There are some platforms like the Intel SG3420P motherboard where this does not appear to be sufficient. Writing to the transmit demand poll register resolves this problem on these troublesome platforms. DAHDI-700 DAHDI-702.

2010-09-21dahdi: Generate include/dahdi/version.h when building in a git repository.Shaun Ruffell
If building within a git repository search the last log message for a 'git-svn-id'. If found, the commit has a corresponding svn revision number and we will use the SVN-xxx-rxxx revision form. Otherwise use the output of 'git describe --long --always --tags --dirty=M' as the version.

2010-09-21dahdi: Make CONFIG_DAHDI_PPP off by default.Shaun Ruffell
Before CONFIG_DAHDI_PPP can be on by default, some more work needs to be done to ensure that the ppp_generic module is not always loaded and that all channels do not carry around all the PPP members unnecessarily.

2010-09-21wctdm24xxp: Add optional FXO digital loopback if DEBUG is defined.Shaun Ruffell
This module parameter will allow patgen/pattest to be used only on FXO ports. *ALL* FXO ports will be placed in digital loopback mode when set. The current intent is for this to be removed as an optional module parameter when there is a channel by channel representation in sysfs. Otherwise, a new IOCTL would have to be defined and a tool written in order to support this. DAHDI-696.

2010-09-20dahdi: Channels can have their own file_operations structure.Shaun Ruffell
If we know that an open file is associated with a channel (pseudo or real) we can just update the file->f_ops pointer so that we can short circuit some of the checks in read/write/poll. Trades sizeof(file_operations) bytes for less function call overhead in the "hot" path. On a 2.4 GHz Xeon, saves around 150 ns on each read / write.

2010-09-20dahdi: Change iteration through pseudo/real chans in process_masterspan.Shaun Ruffell
Since we have the pseudo channels on their own list, we don't need to step through the chans array when we just want to find the pseudo channels. Likewise, all the real channels will have be on a span. Also removes references to the global chans array in process_masterspan.

2010-09-20dahdi: Keep psuedo channels on pseudo_chan_list.Shaun Ruffell
Since pseudo channels are without spans and we would like to use the span list to enumerate through all the channels, keeping the psuedo channels on their own list is required. I believe this is a more natural choice than making a dummy spans for pseudos since pseudo channels should *really* just be an implementation detail that the user shouldn't care about.

2010-09-20dahdi: Remove unit parameter from dahdi_specchan_release.Shaun Ruffell
This change also involves setting the DAHDI_FLAGBIT_CLOSE bit on the channel before calling the 'close' callback in span ops.

2010-09-20dahdi: Remove the unit parameter from dahdi_chan_ioctl.Shaun Ruffell
This ioctl is called either via the "/dev/dahdi/channel" file or via a /dev/dahdi/channo file. In either case, either the minor number of the device file will match up with a channel, or the "private_data" member on the channel will be set, so the unit is redundant.

2010-09-20dahdi: Be more tolerant of surprise removal of channels.Shaun Ruffell
Enable DAHDI to detect if an operation on a file handle refers to a channel that may have been unregistered. This can occur, for example, when a board driver is hot-swapped out in a live system. This patch ensures that file->private_data is always properly set for any open channel, and it's set back to NULL when a channel is unregistered. This way file->private_data can be used to check whether it's valid to perform an operation on the channel. (NOTE: There is still a race condition here if the driver was unbound on one processor during the window of time between when file->private_data was checked and the system call finishes). Also, since DAHDI should only return -ENODEV on read or write when there was a surprise device removal on a running system this sleep can prevent the system from becoming unresponsive if the userspace application does not check for the -ENODEV error and constantly tries to call read with elevated privileges.
