[linux-dvb] AirStar HD5000-PCI signal strength

Hi folks,

I've installed my new(ish) HD5000 card, generally following instructions I've found in other posts (thanks to the various posters!). Kernel is 2.6.15, with Gentoo patches and a few others for ACPI DSDT reloading, and forcedeth and snd_hda_intel upgrades.  I've replaced the kernel dvb drivers with those in CVS.

This all seems to be working, in that I can watch TV in mplayer. However, the signal strength etc are missing from azap output, thus:

test atsc # ./azap -c /tmp/my_channels KNTV
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
tuning to 207000000 Hz
video pid 0x0000, audio pid 0x0000
status 00 | signal 0000 | snr ffff | ber 00000000 | unc 00000000 |
status 1f | signal 0000 | snr ffff | ber 00000000 | unc 00000000 | FE_HAS_LOCK
status 1f | signal 0000 | snr ffff | ber 00000000 | unc 0000003c | FE_HAS_LOCK
status 1f | signal 0000 | snr ffff | ber 00000000 | unc 00000000 | FE_HAS_LOCK
status 1f | signal 0000 | snr ffff | ber 00000000 | unc 00000000 | FE_HAS_LOCK
status 1f | signal 0000 | snr ffff | ber 00000000 | unc 00000000 | FE_HAS_LOCK

Now I've seen mention of a patch, hd5000-cleanup.patch. I can't tell whether this has incorporated into the latest CVS code. The code in CVS seems to have some calculation of signal strength in files frontends/nxt2002.c and b2c2/stv0297_cs2.c, but as you can see above it isn't doing much.

Unfortunately, the hd5000-cleanup patch doesn't seem to be available online any longer, not at its original location on digitalregime, nor anywhere Google has indexed.

Any suggestions, or does anyone have a new pointer to the patch? Or is there some more reasonable way to try to determine signal strength? :/

Thanks in advance,

glen
