* [media] move the dvb/frontends to drivers/media/dvb-frontendsMauro Carvalho Chehab2012-08-131-653/+0
| | | | | | | Raise the DVB frontends one level up, as the intention is to remove the drivers/media/dvb directory. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* [media] cx22702: Fix signal strengthJean Delvare2012-03-081-3/+19
| | | | | | | | | | | | | | | | The signal strength value returned is not quite correct, it decreases when I increase the gain of my antenna, and vice versa. It also doesn't span over the whole 0x0000-0xffff range. Compute a value which at least increases when signal strength increases, and spans the whole allowed range. In practice I get 67% with my antenna fully amplified and 51% with no amplification. This is close enough to what I get on my other DVB-T adapter with the same antenna.

* [media] dvb: Remove ops->info.type from frontendsMauro Carvalho Chehab2012-01-041-1/+0
| | | | | | | | | Now that this field is deprecated, and core generates it for DVBv3 calls, remove it from the drivers. It also adds .delsys on the few drivers where this were missed. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* [media] dvb: don't require a parameter for get_frontendMauro Carvalho Chehab2011-12-311-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | Just like set_frontend, use the dvb cache properties for get_frontend. This is more consistent, as both functions are now symetric. Also, at the places get_frontend is called, it makes sense to update the cache. Most of this patch were generated by this small perl script: while (<>) { $file .= $_; } if ($file =~ m/\.get_frontend\s*=\s*([\d\w_]+)/) { my $get = $1; $file =~ s/($get)(\s*\([^\,\)]+)\,\s*struct\s+dtv_frontend_properties\s*\*\s*([_\d\w]+)\)\s*\{/\1\2)\n{\n\tstruct dtv_frontend_properties *\3 = &fe->dtv_property_cache;/g; } print $file; Of course, the changes at dvb_frontend.[ch] were made by hand, as well as the changes on a few other places, where get_frontend() is called internally inside the driver. On some places, get_frontend() were just a void function. Those occurrences were removed, as the DVB core handles such cases. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* [media] cx22702: convert set_fontend to use DVBv5 parametersMauro Carvalho Chehab2011-12-311-34/+34
| | | | | | | | | | | Instead of using dvb_frontend_parameters struct, that were designed for a subset of the supported standards, use the DVBv5 cache information. Also, fill the supported delivery systems at dvb_frontend_ops struct. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* [media] dvb-core: add support for a DVBv5 get_frontend() callbackMauro Carvalho Chehab2011-12-311-1/+1
| | | | | | | | | | Creates a DVBv5 get_frontend call, renaming the DVBv3 one to get_frontend_legacy(), while not all frontends are converted. After the conversion for all drivers, get_frontend_legacy() will be removed. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* [media] Rename set_frontend fops to set_frontend_legacyMauro Carvalho Chehab2011-12-311-1/+1
| | | | | | | | | | | | | Passing DVBv3 parameters to set_frontend is not fun, as the core doesn't have any way to know if the driver is using the v3 or v5 parameters. So, rename the callback and add a new one to allow distinguish between a mixed v3/v5 paramenter call from a pure v5 call. After having all frontends to use the new way, the legacy call can be removed. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* [media] tuners: remove dvb_frontend_parameters from set_params()Mauro Carvalho Chehab2011-12-311-1/+1
| | | | | | | | | | | This is a big patch, yet trivial: now that all tuners use the DVBv5 way to pass parameters (e. g. via fe->dtv_property_cache), the extra parameter can be removed from set_params() call. After this change, very few DVBv3 specific stuff are left at the tuners. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

* V4L/DVB: cx22702: Simplify cx22702_set_tps()Jean Delvare2010-10-211-32/+26
| | | | | | | | | | Code in function cx22702_set_tps() can be slightly simplified. Apparently gcc was smart enough to optimize it anyway, but it can't hurt to make the code more readable.

* V4L/DVB (12440): Use kzalloc for frontend states to have struct dvb_frontend ↵Matthias Schwarzott2009-08-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 (4028): Change dvb_frontend_ops to be a real field instead of a ↵Patrick Boettcher2006-06-251-7/+4
| | | | | | | | | | | | | | | | | | 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.

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!
