The DSI encoder sets dssdev->ops->dsi.set_config, which is stored at the
same offset as dssdev->ops->hdmi.set_hdmi_mode. The code in omap_encoder
only checks if dssdev->ops->hdmi.set_hdmi_mode is NULL. Due to the way
union works, it won't be NULL if dsi.set_config is set. This means

This adds the required infrastructure for manually updated displays,
such as DSI command mode panels. While those panels often support
partial updates we currently always do a full refresh.
The display will be refreshed when something calls the dirty callback,
such as libdrm's drmModeDirtyFB().
While most display types only forward their VM to the DISPC, this
is not true for DSI. DSI calculates the VM for DISPC based on its
own, but it's not identical. Actually the DSI VM is not even a valid
DISPC VM making this check fail. Let's restore the old behaviour
and avoid checking the DISPC VM

Now that the plane code takes the underscan setup into account, we can
safely attach the underscan props to the HDMI connector.
We also take care of filling AVI infoframes correctly to expose the

Note that these underscan props match pretty well the

- Fix for fastboot DSI panel boot
Hi Jerome,
Bit late reply, but here goes :)
We're working quite hard to avoid pinning any pages unless they're in
the GPU page tables. And when they are in the GPU page tables, they must
be pinned for whole of that duration, for the reason that our GPUs can
not take a fault. And to avoid
This reverts commit 0efd2d2f68cd5dbddf4ecd974c33133257d16a8e.
It's still causing problems for V3D.
v2: keep rearming the timeout.

For real commits we WARN if ->hw_done hasn't been completed by the time
drm_atomic_helper_commit_cleanup_done() is called. Let's do the same for
the fake commit.

Consider the following scenario:
1. nonblocking enable crtc
2. wait for the event
3. nonblocking disable crtc
On i915 this can lead to a spurious -EBUSY from step 3 on
account of non-enabled planes getting the fake_commit in step 1
and we don't complete the fake_commit->

From the dmesg output, it looks like the AMD GPU is powered off most of the
time. Do the freezes happen when you explicitly use it for something, e.g. for
a game via DRI_PRIME=1?

arch_add_memory is not exported, and it really should not be.

Most callers could handle the failure correctly. It looks like the

Since Linux 4.17, calls to drm_crtc_vblank_on/off are mandatory, and we get
a warning when ctrc is disabled :
" driver forgot to call drm_crtc_vblank_off()"
But, the vsync IRQ was not totally disabled due the transient hardware
state and specific interrupt line, thus adding proper IRQ masking

Hi all,
We're having some good fun with the i915 mmu notifier (it deadlocks), and
I think it'd be very useful to have a bunch more runtime debug checks to
catch screw-ups.
I'm also working on some lockdep improvements in gpu code (better
annotations and stuff like that). Together with this
This is a similar idea to the fs_reclaim fake lockdep lock. It's
fairly easy to provoke a specific notifier to be run on a specific
range: Just prep it, and then munmap() it.
A bit harder, but still doable, is to provoke the mmu notifiers for
all the various callchains that might lead to them.
Just a bit of paranoia, since if we start pushing this deep into
callchains it's hard to spot all places where an mmu notifier
implementation might fail when it's not allowed to.
