Eventhough the delivery system is made standalone, DVBFE_SET_DELSYS needs to be set as the very first operation, for a multistandard frontend Splitting delivery system out as a new ioctl, makes things a bit more easier to understand. Signed-off-by:

Optimizations galore: Blistering barnacles! The KNC1 and friends like 90 Mhz clock much better rather than running at a higher throttle, for almost similar hardware. he exact cause unknown, possibly due to a lower voltage applied for the demod power supply. Signed-off-by:

* cut down some I/O operations by disabling "disable gate" * budget_av was left with the gate open, thereby more susceptible to RF interference due to I/O operations Signed-off-by:

Bug #1: The 5 tap equaliser is set to correct simple perturbations like reflections on the IF cable for DVB-S. In the case of DVB-S2 a more powerful equalizer is used to correct the filter group delay allowing the bandwidth to be reduced by a factor of 1/3 Bug #2: The ZIF tuner takes badwidth to be set in Hz Signed-off-by:

Note: * At High Symbol Rates we do not have enouph machine cycles to handle the incoming symbols and hence might run into problems at the very end of the specified definition * Most of the equations have been calculated for a master clock of 99 MHz, running at 90MHz, raises lot of issues such as the need to recalculate all of them , which is eventually very painful.

The Bug was found by Arvo Jarve <arvo@softshark.ee> It was a wonder how it worked in the case with this bug, STM verified this that this nibble was in fact insignificant and can be ignored. But still we need to fix all inconsistencies. Signed-off-by:

In this case, we will be sure that there exists a carrier and the center frequency would be simply f1 - f2. In such a circumstance, the TR loop is simplified to doing a simple check for timing, rather than searching for the same. Signed-off-by:

BUG! Setting CRL parameter overwrote the CR Algorithm type, eventually leading to wrong search algorithm to be employed in the DVB-S carrier loop optimization. Symptom: Once the CR optimization stage is passed either way, in a successful or failed manner, the very next carrier search will fail, due to no Carrier Search Algorithm specified. Signed-off-by:
