[PATCH 1/2] drm/i915/bios: Tolerate devdata==NULL in intel_bios_encoder_supports_dp_dual_mode()

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

If we have no VBT, or the VBT didn't declare the encoder
in question, we won't have the 'devdata' for the encoder.
Instead of oopsing just bail early.

We won't be able to tell whether the port is DP++ or not,
but so be it.

[PATCH 2/2] drm/i915/bios: Use the platform's port_mask when there is no VBT

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

When we have no VBT we currently assume ports A-F are
all pontially valid for every platform. That is nonsense.
Grab the bitmask of valid ports from the runtime info
instead.

Although the defaults we actually fill here look semi-sensible
only for hsw-skl era hardware. Dunno if we should try to do
something more appropriate here for other platforms,
or just try to nuke the whole thing?

Seems like doing something appropriate is an endless task. We should
never have added the defaults, but here we are. Can we remove them for
newer platforms? There's only one way to find out...

Commit 828ccb31cf41 ("drm/i915/icl: Add TypeC ports only if VBT is
present") fails to mention if this was to address a real issue on ICL
without VBT, or just playing it safe.

I was wondering why we don't just

-#define for_each_port(__port) \
-	for ((__port) = PORT_A; (__port) < I915_MAX_PORTS; (__port)++)
+#define for_each_port(__i915, __port)					\
+	for_each_set_bit(__port, &DISPLAY_RUNTIME_INFO(__i915)->port_mask, sizeof(DISPLAY_RUNTIME_INFO(__i915)->port_mask))

but then we have DSI code that relies on it returning PORT_A for DSI.

Ugh. It's all so brittle.

Anyway, the patch is

The above oopses already.

Nope. It's just taking the address of the thing.

I guess. Still looks a bit suspicious. :/
