480i no longer working under fkms

Open alanbork opened this issue 3 years ago • 5 comments

As of efe79c1df6df24e666c08dd68e1636ed24210fc1, switching into 480i causes my TV to report "no signal". This is outside of x, using modetest. I don't see any error messages in dmesg.

reverting back to 9dbcd6dfed16cc7de4a67b9ca445c4847f68c4c2 fixes it. I can search through the revisions in between if you have any suggests of likely candidates, but it's a lot to just try blindly.

Can you try https://github.com/Hexxeh/rpi-firmware/commit/f8357e4d1dbc6b98dcec9acae9dbba5d9fb86040 and the one before? That's one commit that would affect 480i.

f8357e4d1dbc6b98dcec9acae9dbba5d9fb86040 still has the problem. 64132d67d3e083076661628203a02d27bf13203c (which seems to be the next oldest release) fixes it. So it seems that f8357e4d1dbc6b98dcec9acae9dbba5d9fb86040 is where the regression happens.

Was this ever fixed?

I believe interlaced output is now working on fkms and kms. Have you tried recently? You'll probably want to test rpi-update firmware/kernel currently - although apt should be updated to match that this week.
