The boundary is widened to start at -9. In order to save time, if no carrier is detected at the start it advances to the next alignment until carrier is found. The stv0288 will detect a DVB-S2 carrier on all steps , a time out of 11 steps is introduced to drop out of the loop. In stv0288_set_symbol carrier and timing loops are restored to default values (inittab) before setting the symbol rate on each tune.

Digital tuners like tda18271, xc3028, etc. generally allow changing the IF frequency, although they generally have recommented settings for the IF. Analog tuners, have a fixed IF frequency, that depends on the physical characteristics of some analog components. For digital tuners, it makes sense to have ways to configure IF, via the tuner's configuration structure, like what's done inside the tda18271-fe maps. The demods need to know what IF is used by the tuner, as it will need to convert internally from IF into baseband. Currently, the bridge driver needs to fill a per-demod configuration struct for it, or pass it via a dvb_attach parameter. The tda18271 datasheet recommends to use different IF's for different delivery system types and for different bandwidths. The DRX-K demod also needs to know the IF frequency in order to work, just like all other demods. However, as it accepts different delivery systems (DVB-C and DVB-T), the IF may change if the standard and/or bandwidth is changed. So, the usual procedure of passing it via a config struct doesn't work. One might try to code it as two separate IF frequencies, or even as a table in function of the delivery system and the bandwidth, but this will be messy. So, it is better and simpler to just add a new callback for it and require the tuners that can be used with MFE frontends like drx-k to implement a new callback to return the used IF.

* [media] tda18271c2dd: Fix saw filter configuration for DVB-C @6MHzMauro Carvalho Chehab2011-07-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the driver assumes that all QAM carriers are spaced with 8MHz. This is wrong, and may decrease QoS on Countries like Brazil, that have DVB-C carriers with 6MHz-spaced. Fortunately, both ITU-T J-83 and EN 300 429 specifies a way to associate the symbol rate with the bandwidth needed for it. For ITU-T J-83 2007 annex A, the maximum symbol rate for 6 MHz is: 6 MHz / 1.15 = 5217391 Bauds For ITU-T J-83 2007 annex C, the maximum symbol rate for 6 MHz is: 6 MHz / 1.13 = 5309735 Bauds. As this tuner is currently used only for DRX-K, and it is currently hard-coded to annex A, I've opted to use the roll-off factor of 0.15, instead of 0.13. If we ever support annex C, the better would be to add a DVB S2API call to allow changing between Annex A and C, and add the 0.13 roll-off factor to it. This code is currently being used on other frontends, so I think we should later add a core function with this code, to warrant that it will be properly implemented everywhere.

* [media] au8522: set signal field to 100% when signal presentDevin Heitmueller2011-07-27
| | | | | | | | | | | | The signal state field in G_TUNER is typically scaled from 0-100%. Since we don't know the signal level, we really would prefer the field to contain 100% than 1/256, which in many utilities (such as v4l2-ctl) rounds to 0% even when a signal is actually present. This patch makes the behavior consistent with other drivers. Signed-off-by: Devin Heitmueller <dheitmueller@kernellabs.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* [media] drxk: Fix the logic that selects between DVB-C annex A and CMauro Carvalho Chehab2011-07-27
| | | | | | | | | | | | | | Fix the DRX-K logic that selects between DVB-C annex A and C Fix a typo where DVB-C annex type is set via setEnvParameters, but the driver, uses, instead, setParamParameters[2]. While here, cleans up the code, fixing a bad identation at the fallback code for other types of firmware, and put the multiple-line comments into the Linux CodingStyle.

* [media] drxk: Fix a bug at some switches that broke DVB-TMauro Carvalho Chehab2011-07-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The error propagation changeset c23bf4402 broke the DVB-T code. The legacy way for propagate errors was: do { status = foo_func() if (status < 0) break; } while (0); return status; However, on a few places, it was doing: do { switch(foo) { case bar: status = foo_func() if (status < 0) break; break; } switch(foo2) { case bar: status = foo_func() if (status < 0) break; break; } ... } while (0); return (status) The inner error break were not working, as it were breaking only the switch, instead of the do. The solution used were to do a s/break/goto error/ at the inner breaks, but preserving the last break. Onfortunately, on a few switches, the replacement were applied also to the final break for the case statements. Fix the broken logic, by reverting them to break, where pertinent, in order to fix DVB-T support. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* [media] Remove the double symbol increment hack from drxk_hardMauro Carvalho Chehab2011-07-27
| | | | | | | | | | | | | | Both ngene and ddbrige calls dvb_attach once for drxk_attach. The logic used there, and by tda18271c2dd driver is different from similar logic on other frontends. The right fix is to change them to use the same logic, but, while we don't do that, we need to patch em28xx-dvb in order to do cope with ngene/ddbridge magic. While here, document why drxk_t_release should do nothing. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* [media] media, Micronas dvb-t: Fix mem leaks, don't needlessly zero mem, fix ↵Jesper Juhl2011-07-27
| | | | | | | | | | | | | | | | | | | | | | | | spelling In drivers/media/dvb/frontends/drxd_hard.c::load_firmware() I see 3 small issues: 1) When the 'fw' variable goes out of scope we'll leak the memory allocated to it by request_firmware() by neglecting to call release_firmware(). 2) After a successful request_firmware() we allocate fw->size bytes of memory using kzalloc() only to immediately overwrite all that memory with memcpy(), so asking for zeroed memory seems like wasted effort - just use kmalloc(). 3) In one of the error messages "no memory" lacks a space and is written as "nomemory". This patch fixes all 3 issues. Signed-off-by: Jesper Juhl <jj@chaosbits.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
