4.17-rc2: Could not determine valid watermarks for inherited state

4.17-rc2: Could not determine valid watermarks for inherited state

[Dave Jones]

This warning just started appearing during boot on a machine I upgraded
to 4.17-rc2.  The warning seems to have been there since 2015, but it
has never triggered before today.

Looks like we have bug open about this. I just asked for more

https://bugs.freedesktop.org/show_bug.cgi?id=105992#c5

If you can also boot with drm.debug=0xe maybe we can see some more

OK, so that's the problem right there. The fb we took over from the
BIOS was 800x600, but now we're trying to set up a 1366x768 mode.

We seem to be missing checks to make sure the initial fb is actually
big enough for the mode we're currently using :(

Actually we do read out the pipe src size as 800x600 initially, which
make sense. And we even stuff that into the mode.h/vdisplay, so up to
that point everything is pretty much correct. It goes wrong is when
intel_modeset_readout_hw_state() calls intel_mode_from_pipe_config()
as that will override the h/vdisplay with the actual crtc timings
instead of the pipe src size.

So I suppose we should be able to just add the sanity checks for the
fb vs. h/vdisplay, and at least we should get past this error. A
slightly bigger mystery is what will happen later when our pipe src
size doesn't actually agree with the h/vdisplay. The first modeset
will correct it, but we might want some kind of extra sanitize step
for fastboot type of stuff.

Hmm. Or maybe we should just stick to the pipe src size.

I'm curious whether this fixes the problem?

It does!
