i915_gem_retire_requests() is the sole path on which we can transition

scheduled the idle worker.

This is fallout from changing the routine from considering active_engines

v2: Move kicking the idle working to i915_gem_request_retire() otherwise
we could postpone the idle callback everytime we called retire_requests
even though we did no work.

For a bit of extra backwards compatilbilty the kernel will allow

This in case there's existing userspace out there that sets
modifier[1+] to something non-zero with planar formats.

    drm/i915: set DIDL using the ACPI video output device _ADR method return.

which went out of its way to cater to a specific BIOS, setting up DIDL
based on _ADR method. Perhaps that approach worked on that specific
machine, but on the machines I checked the _ADR method invents the
device identifiers out of thin air if DIDL has not been set. The source
for _ADR is also supposed to be the DIDL set by the driver, not the
other way around.

With this, we'll also limit the number of outputs to what the driver
actually has.

A side effect of this change is that the DIDL, and by proxy CADL, will
be initialized in the order of the connector list. That, in turn, has
internal panels in front, ensuring they're included in the DIDL and CADL
lists. Hopefully this ensures the BIOS does not block backlight hotkey
events, thinking the internal panel is off.

v2: do not set ACPI_DEVICE_ID_SCHEME in the device id (Peter Wu)

v3: Rebase

8 years agodrm/i915: fix the dequeue logic for single_port_submission context

drm/i915: fix the dequeue logic for single_port_submission context

For a single_port_submission context, GVT expects that it can only be
submitted to port 0, and there shouldn't be any other context in port 1
at the same time. This is required by GVT-g context to have an opportunity
to save/restore some non-hw context render registers.

This patch is to workaround GVT-g.

v2: optimized code by following Chris's advice, and added more comments to
explain the patch.
v3: followed the coding style.
