Subject: [PATCH] drm/i915/dp: Use DRM_ERROR not WARN for sanity checks
|
|
||||||
|
|
||||||
These are noisy as shit and creating a ton of abrt reports. I don't
|
|

need more, thanks. Proper fix upstream eventually.

Subject: drm/i915: Check VBIOS value for determining LVDS dual channel mode, too
|
|
||||||
|
|
||||||
Currently i915 driver checks [PCH_]LVDS register bits to decide
|
|
||||||
whether to set up the dual-link or the single-link mode. This relies
|
|
||||||
implicitly on that BIOS initializes the register properly at boot.
|
|
||||||
However, BIOS doesn't initialize it always. When the machine is
|
|
||||||
booted with the closed lid, BIOS skips the LVDS reg initialization.
|
|
||||||
This ends up in blank output on a machine with a dual-link LVDS when
|
|
||||||
you open the lid after the boot.
|
|
||||||
|
|
||||||
This patch adds a workaround for that problem by checking the initial
|
|
||||||
LVDS register value in VBT.

||||||

The default VGA device is a somewhat fluid concept on platforms with
|
|
||||||
multiple GPUs. Add support for setting it so switching code can update
|
|
||||||
things appropriately, and make sure that the sysfs code returns the right
|
|
||||||
device if it's changed.

vga-switcheroo currently changes the default VGA device by fiddling with
|
|
||||||
the IORESOURCE_ROM_SHADOW flag on the device. This isn't strictly accurate,
|
|
||||||
since there's no guarantee that switching also changes the ROM decoding.
|
|
||||||
Switch over to using the vgaarb functions for this.

IORESOURCE_ROM_SHADOW is not necessarily an indication that the hardware
|
|
||||||
is the primary device. Add support for using the vgaarb functions and
|
|
||||||
fall back if nothing's set them.

EFI doesn't typically make use of the legacy VGA ROM, but it may still be
|
|
||||||
configured to pass that through to a given video device. This may lead to
|
|
||||||
an inaccurate choice of default video device. Add support to efifb to pick
|
|
||||||
out the correct active video device.

Since Matthew's efi/vga changes on non-EFI machines we were failing
|
|
||||||
to tell the vgaarb/switcheroo what the default device was, this
|
|
||||||
sets the default device in the quirk if none has been set before.
|
|
||||||
|
|
||||||
This fixes the switcheroo on my T410s.
|
|
||||||
|
|
||||||
[hpa: please ack to put this on top of the other patches in my -next tree].
