That's OK - nouveau doesn't let you pick bit depth either (yet). It's
all 8bpc - higher bpc mode support will come ... eventually.

I think I may have updated the tv firmware between when it worked and
when it didn't.
I wonder it it has to do with bit depth.
I use lubuntu and it doesn't let me pick the bit depth so I don't know
what it using.

I still only get 30Hz.
I did just update the tv firmware s9 maybe that is why I can't get it 60Hz

Can you try something very simple - unplug the cable, and plug it back
in, while the TV is on, and set to the HDMI input? That should ensure

We only need the special pud_entry walker if PUD-sized hugepages and

All users pass PAGE_SIZE here, and if we wanted to support single
