Notes:
Note that to use this with either of the DVICO FusionHDTV DVB-T boards you
will need to fetch and build against a recent snapshot of the video4linux
code that you can obtain from http://dl.bytesex.org/cvs-snapshots/. This
will get you the board ID for the Lite board, and/or the kernel I2C
support needed for the DVB-T1.
Cleanups (mt352-0-cleanup.patch) include:
- moving the card_type and dvb_frontend_info structure into the adapter
state to permit more than one card type in a system at once converting
the force_card parameter to an array to permit the same;
- removing incorrect "shift" values reintroduced by the merge of the
TDTC9251DH01C driver which was based on an old version of the code
with incorrect values - changes discussed and tested by Antonio
Mancuso;
- removing the incorrect use of I2C_M_NOSTART from the driver. The
only boards where this worked were the boards where use_i2c_hw
was enabled in the bttv driver, and there only because the i2c_hw
code ignores the I2C_M_NOSTART flag and always generates a start
condition. On other boards where the clag is respected, this
violates the i2c protocol and causes only errors. No-op;
- cleaning up some double initialisation (specifically that of the
ACQ_CTL register - no-op;
- converts some routines to pass the true frequency around, rather
than the frequency in MHz - need the real frequency for other
boards - no-op;
- ignoring FEC_NONE for the LP coderate in the case where OFDM
hierarchy mode is either set to be auto-detected or is disabled.
The demodulator ignores our settings anyway;
- changing the detect_avermedia function to a more generic function
that can be used to detect other bt878 or cx2388x cards in a
similar way;
- rounding the frequency programmed into the PLL so that it will be
closer to the desired received frequency;
- decoupling requirement for FE_REGISTER/FE_UNREGISTER to be called
synchronously from within mt352_attach_adapter/mt352_detach_client,
so that mt352 can be used with drivers such as cx88 which have
i2c and DVB support in separate modules.
The DVICO hardware support (mt352-1-dvico.patch):
- introduces functionality for the DVICO FusionHDTV DVB-T1 and
DVICO FusionHDTV DVB-T Lite boards in the mt352 frontend;
- activates autodetection for these boards;
The dvb-bt8xx patch (dvb-bt8xx.patch):
- adds hardware support for the DVICO FusionHDTV DVB-T Lite
- adds functionality to the bt8xx code to switch on/off DMA of the
transport stream only when the DVB layer wants data, rather than
generating a constant interrupt stream the entire time that the
driver is loaded.
The mt352 speedup patch (mt352-2-speedups.patch) helps with tuning
speed on the mt352 frontend, by:
- reinitialising the frontend only in the case when it has not yet
been initialised or when it has been put to sleep;
- ignoring requests from the frontend thread to repetitively acquire
a transponder with the same parameters. Each time it does this,
the tuner/demodulator lose sync and acquisition time is needlessly
extended.

included just everywhere
- remove dvb_i2c.[ch], it's not needed anymore
- rename dvb_register_frontend_new() to dvb_register_frontend()
-

(should fix mt352 detection)

- MODULE_PARM* -> module_param*
- Common name for I2C device and prefix for debug messages.
NOTE: This needs testing by someone who has one of these frontends.

running...
|
|
Also some minimal budget-ci CI support implemented (just detection+IRQs)
|
|
Not all ioctls are fully supported yet.
