* V4L/DVB (12440): Use kzalloc for frontend states to have struct dvb_frontend ↵Matthias Schwarzott2009-08-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | properly This patch changes most frontend drivers to allocate their state structure via kzalloc and not kmalloc. This is done to properly initialize the embedded "struct dvb_frontend frontend" field, that they all have. The visible effect of this struct being uninitalized is, that the member "id" that is used to set the name of kernel thread is totally random. Some board drivers (for example cx88-dvb) set this "id" via videobuf_dvb_alloc_frontend but most do not. So I at least get random id values for saa7134, flexcop and ttpci based cards. It looks like this in dmesg: DVB: registering adapter 1 frontend -10551321 (ST STV0299 DVB-S) The related kernel thread then also gets a strange name like "kdvb-ad-1-fe--1".

* V4L/DVB (11723): Link firmware to physical deviceJean Delvare2009-06-16
| | | | | | | | | | | Use the physical device rather than the i2c adapter as the reference device when loading firmwares. This will prevent the sysfs name collision with i2c-dev that has been reported many times. I may have missed other drivers which need the same fix.

* V4L/DVB (5374): Or51132: refactor i2c code, improve error resilienceTrent Piepho2007-04-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The code the i2c transactions was leftover from the old V4L-based ATSC driver. It did too little with too much code. It is re-written to remove unnecessary parameters and be more efficient. A demod register can now be read with one function call, instead of repeating a dozen line block of code each time. There were msleep()'s, which appear to be unnecessary, spread around all the I2C transactions. These have been removed. Reading SNR used to take about 130 ms, now it's down to 1.8 ms. Reads from the demodulator's registers do not return correct results sometimes. Adding or removing the delays in the I2C transactions did not appear to effect the probability of failure. If anything, the transactions without delays were less likely to fail, but since far more transactions could be made per second the number of failures per hour was greater. To increase reliability, the SNR and get_params functions will now retry once if they get bad data back. This appears to have reduced the probability of failure to effectively zero. Some error messages are cleaned up or given KERN_* levels when they were missing. or51132_setmode() wasn't returning correct error codes, which is fixed as well.

* V4L/DVB (4028): Change dvb_frontend_ops to be a real field instead of a ↵Patrick Boettcher2006-06-25
| | | | | | | | | | | | | | | | | | pointer field inside dvb_frontend The dvb_frontend_ops is a pointer inside dvb_frontend. That's why every demod-driver is having a field of dvb_frontend_ops in its private-state-struct and using the reference for filling the pointer-field in dvb_frontend. - It saves at least two lines of code per demod-driver, - reduces object size (one less dereference per frontend_ops-access), - be coherent with dvb_tuner_ops, - makes it a little bit easier for newbies to understand how it works and - avoids stupid mistakes because you would have to copy the dvb_frontend_ops always, before you could assign the static pointer directly, which was dangerous.

* V4L/DVB (3723): Avoid unnecessary firmware re-loads in or51132 frontendTrent Piepho2006-06-25
| | | | | | | | | | | | | As QAM_64, QAM_256, and QAM_AUTO all use the same firmware, switching between these modulations doesn't require a firmware re-load. This also fixes a mishandled error condition, in which the firmware file is loaded into the kernel, the clock mode is changed, but then the firmware upload to the device fails. The modulation change is aborted, but the clock mode would still be changed.

* [PATCH] fix missing includesTim Schmielau2005-10-30
| | | | | | | | | | | | | | | | | | | | | I recently picked up my older work to remove unnecessary #includes of sched.h, starting from a patch by Dave Jones to not include sched.h from module.h. This reduces the number of indirect includes of sched.h by ~300. Another ~400 pointless direct includes can be removed after this disentangling (patch to follow later). However, quite a few indirect includes need to be fixed up for this. In order to feed the patches through -mm with as little disturbance as possible, I've split out the fixes I accumulated up to now (complete for i386 and x86_64, more archs to follow later) and post them before the real patch. This way this large part of the patch is kept simple with only adding #includes, and all hunks are independent of each other. So if any hunk rejects or gets in the way of other patches, just drop it. My scripts will pick it up again in the next round.

* [PATCH] dvb: frontend: or51132: remove bogus optimization attemptMac Michaels2005-09-09
| | | | | | | | | | | | | | | | | | This fix has also been applied to lgdt330x. There is an optimization that keeps track of the frequency tuned by the digital decoder. The digital driver does not set the frequency if it has not changed since it was tuned. The analog tuner driver knows nothing about the frequency saved by the digital driver. When the frequency is set using the video4linux code with tvtime, the hardware get changed but the digital driver's state does not get updated. Switch back to the same digital channel and the driver finds no change in frequency so the tuner is not reset to the digital frequency. The work around is to remove the check and always set the tuner to the specified frequency.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
