I just tested your patch set and it didn't work: my monitor reported
1920x539 at 50Hz. We're missing something from patch "fixup interlace
vertical timings confusion". The reg dump is attached.
By the way, VTOTAL_B was 1078. We need to remove those "-1" and also
those "-2". Look at ironlake_crtc_mode_set: we already do the
subtractions when we write to HSYNC, HTOTAL, etc. From the register
descriptions, those -1 are independent of interlaced or
non-interlaced. I believe there was some confusion with these
registers because intel_reg_dumper already re-adds +1 when showing the
register values.
Btw, git clone on fd.o is slow today :(
