3 years agodrm: rcar-du: Fix crash when using LVDS1 clock for CRTC

drm: rcar-du: Fix crash when using LVDS1 clock for CRTC

On D3 and E3 platforms, the LVDS encoder includes a PLL that can
generate a clock for the corresponding CRTC, used even when the CRTC
output to a non-LVDS port. This mechanism is supported by the driver,
but the implementation is broken in dual-link LVDS mode. In that case,
the LVDS1 drm_encoder is skipped, which causes a crash when trying to
access its bridge later on.

Fix this by storing bridge pointers internally instead of retrieving
them from the encoder. The rcar_du_device encoders field isn't used
anymore and can be dropped.

drm: Add default modes for connectors in unknown state

The DRM CRTC helpers add default modes to connectors in the connected

useful for VGA or DVI outputs that have no connected DDC bus. However,

is reported as connector_status_unknown.

3 years agodrm/i915: Fix mismatch between misplaced vma check and vma insert
Chris Wilson [Wed, 16 Dec 2020 09:29:51 +0000 (09:29 +0000)]
drm/i915: Fix mismatch between misplaced vma check and vma insert

When inserting a VMA, we restrict the placement to the low 4G unless the
caller opts into using the full range. This was done to allow usersapce
the opportunity to transition slowly from a 32b address space, and to
avoid breaking inherent 32b assumptions of some commands.

However, for insert we limited ourselves to 4G-4K, but on verification
we allowed the full 4G. This causes some attempts to bind a new buffer
to sporadically fail with -ENOSPC, but at other times be bound
successfully.

commit 48ea1e32c39d ("drm/i915/gen9: Set PIN_ZONE_4G end to 4GB - 1
page") suggests that there is a genuine problem with stateless addressing
that cannot utilize the last page in 4G and so we purposefully excluded
it. This means that the quick pin pass may cause us to utilize a buggy
placement.

we set a deferred reason in case a dependency fails to probe (which
quickly happens on small config/DT changes due to the rather long probe
chain which can include bridges, phys, panels, backights, leds, etc.).
