Hey,
(CCing some people who have worked on the i915 code recently)
I've had this bug on my x240t since a while now. I mentioned it a while back on
this list[1], but I didn't look very deep back then.
In short: display port on docking station (HDMI2 in xrandr) doesn't always
detect a monitor. Sometimes you can get it to work by suspending and resuming.
Having found no clues from trying a load of different combinations of docking,
undocking, changing power states, plugging and unplugging monitors etc, I
finally decided to start reading code. I've made some progress, but I've hit a
brick wall. I'm hoping someone can point me in the right direction.
The code responsible for detecting monitors on HDMI ports is
intel_hdmi_detect() in intel_hdmi.c. This calls up into drm_get_edid() in
drm_edid.c. This then uses the i2c bus on the graphics card to query the port.
The i2c bus code is custom for the i915 graphics card: intel_i2c.c.
It seems that the difference between a successfully detected and a
unsuccessfully detected HDMI2 boils down to whether the call to I915_READ() on
line 210 of intel_i2c.c is successful.
for (retries = 50; retries > 0; retries--) {
st = I915_READ(GMBUS2 + reg_offset);
if (st & (GMBUS_SATOER | GMBUS_HW_RDY))
break;
DELAY(1000);
}
if (st & GMBUS_SATOER) {
bus_err = 1;
goto out;
}
In the case where a monitor is plugged in but X fails to detect it, the call
returns GMBUS_SATOER. In cases where HDMI2 is detected properly, the function
exits without error.
I've gotten this far with printf debugging. The existence of my printf's seems
to have changed the behaviour, so I'm wondering if there is a race some place.
It used to be the case that a zzz/resume cycle would *always* cause HDMI2 to
be detected OK. But since adding my printfs, HDMI2 is not reliably detected
with the zzz/resume cycle any more.
I've not been able to find a description of GMBUS_SATOER anywhere, but I
think this should not happen, right? Hopefully I'm not chasing a red
herring.
