EDID parsing in S3 resume pushes new display modes
to probed_modes list but doesn't consolidate to actual
mode list. This creates a race condition when
amdgpu_dm_connector_ddc_get_modes() re-initializes the
list head without walking the list and results in memory leak.

It is believed that all of the current users of the "unprepare" delay

On the panel I'm looking at, there's an 80 ms minimum time between HPD
being asserted by the panel and setting the backlight enable GPIO.
While we could just add an 80 ms "enable" delay, this is not ideal.
Link training is allowed to happen in parallel with this delay so the

This is an RFC to add an Adreno GPU specific handler for pagefaults. The first

When removing the tidss driver, there is a warning reported by
kernel about an unhandled interrupt for mhdp driver.
[ 43.238895] irq 31: nobody cared (try booting with the "irqpoll" option)
... [snipped backtrace]
[ 43.330735] handlers:

bus_flags can be specified by a bridge in the timings.
If the bridge provides it, Override the bus_flags when propagating
from next bridge.

To be able to support connector operations across multiple
bridges, it is recommended that the connector should be
created by the SoC driver instead of the bridges.
Modify the tidss modesetting initialization sequence to
create the connector and attach bridges with flag
When there is a chain of bridges attached to the encoder,
the bus_format should be ideally set from the input format of the
first bridge in the chain.
Use the bridge state to get the negotiated bus_format.
If the bridge does not support format negotiation, error out
and fail.
Signed-off-by:
With new connector model, tfp410 will not create the connector and
SoC driver will rely on format negotiation to setup the encoder format.
Support format negotiations hooks in the drm_bridge_funcs.
Use helper functions for state management.
Output format is expected to be MEDIA_BUS_FMT_FIXED
With new connector model, mhdp bridge will not create the connector and
SoC driver will rely on format negotiation to setup the encoder format.
Support minimal format negotiations hooks in the drm_bridge_funcs.
Complete format negotiation can be added based on EDID data.
This patch adds the
This series moves the tidss to using new connectoe model, where the
SoC driver (tidss) creates the connector and all the bridges are
attached with the flag DRM_BRIDGE_ATTACH_NO_CONNECTOR
Since the bridges do not create the connector, the bus format and
bus_flag is set after the format

whoops, you can ignore this actually - I got this mixed up with an Intel issue I
was looking at, this is actually a nouveau issue and you guys don't need to look
at this :)
Kirill-I'll get to this asap, but I've got some other stuff on my plate to go
through first. Could you open up a bug on
Implement the new driver method 'reg_user_mr_dmabuf'. Utilize the core

dma_virt_ops is used by virtual devices that map pages / scatterlists to
virtual addresses for CPU access instead of performing DMA. This is not
the intended use of dma_buf_attach() and dma_buf_map_attachment(). CPU
access of dma-buf should use dma_buf_vmap() and related functions.

Dma-buf is a standard cross-driver buffer sharing mechanism that can be
used to support peer-to-peer access from RDMA devices.
Device memory exported via dma-buf is associated with a file descriptor.
This is passed to the user space as a property associated with the
buffer allocation. When the
