[Intel-gfx] source-based replacement for video bios on ivybridge -- I'm stuck!

[ron minnich]

Thanks for the suggestions, I did move forward to 3.6-rc1.

It gives me lots of messages I expect, but does not yet work...

I'm still convinced there is some basic thing I'm not setting up
right; still getting these pipe0 stuck messages. Now, the one thing
I'm definitely doing different than the driver, after a discussion
with Jesse, is not setting up the ring or status page. It's not
supposed to be needed for this basic set up.

It all starts to go sour here:
[000000.0] [drm:ironlake_edp_panel_on], Turn eDP power on
[000000.0] [drm:ironlake_wait_panel_power_cycle], Wait for panel power cycle
[000000.0] [drm:ironlake_wait_panel_status], mask b800000f value
00000000 status 00000000 control abcd0008
[000000.0] [drm:ironlake_wait_panel_on], Wait for panel power on
[000000.0] [drm:ironlake_wait_panel_status], mask b000000f value
80000008 status 0000000a control abcd000b
[000000.0] [drm:ironlake_edp_panel_vdd_off], Turn eDP VDD off 1
[000000.0] [drm:ironlake_panel_vdd_off_sync], PCH_PP_STATUS:
0x80000008 PCH_PP_CONTROL: 0xabcd0003
[000000.0] [drm:intel_dp_start_link_train], too many voltage retries, give up

And then we get no further (after several iterations) than the voltage
retries. Any further suggestions welcome :-)
