The feature allows the guest request an EDID blob (describing monitor
capabilities) for a given scanout (aka virtual monitor connector).
It brings a new command message, which has just a scanout field (beside
the standard virtio-gpu header) and a response message which carries the
EDID data.

Hello,
This small patch series adds support for the M3-N internal LVDS encoder in the
DT bindings, the LVDS encoder driver and the M3-N .dtsi.
Please see individual patches for details.
The series is based on a merge of Simon's devel branch and the DRM -next
branch.

The DSI devices have a maximum operating frequency specified

that can scale their frequency need this information to set

The majority of drivers use drm_gem_prime_export() and
drm_gem_prime_import() for these callbacks so let's make them the

This adds an optional function table on GEM objects.

This patchset adds a library for shmem backed GEM objects and makes use
of it in tinydrm.
Daniel suggested that I make a generic mmap function for GEM PRIME.
I wondered if I could make it the default for drm_driver->gem_prime_mmap

This move makes tinydrm useful for more drivers. tinydrm doesn't need
continuous memory, but at the time it was convenient to use the CMA
library. The spi core can do dma on is_vmalloc() addresses making this
possible.

This patch attempts to make use of the hardware counters for GPU busy %
estimation when possible and skip using the software counters as it also
accounts for software side delays. This should help give more accurate
representation of the GPU workload.

The gpu_busy() function turns out is useful for performance profiling as
well. So we change the input params to pass in the pointer to the previous
busy cycles, this makes the function more generic and removes the dependency
on the gpu devfreq.

I was looking for a simple mechanism to measure GPU workloads, it turns out
that the support is already present in the msm driver. In this series I try to
make use of the hardware counters where possible for a more accurate workload
estimation. Please review and share your thoughts on this.

Moving this to resume helps with both GPU DCVS and the performance
sampling. For GPU DCVS this makes sure that the frequency does not scale
when there are no GPU submissions. In the case of performance profiling,
the GPU is UP, but its possible that the hw_init() was not called yet,
so we need this

On BYT and CHT the GOP sometimes initializes the pclk at a (slightly)
different frequency then the pclk which we've calculated.
This commit makes the DSI code read-back the pclk set by the GOP and
if that is within a reasonable margin of the calculated pclk, uses
that instead.

Hi All,
I've send v1 of this a while ago. Unfortunately I did not have time
to respin this until now.
This version uses intel_encoder_current_mode() as suggested in the
discussion of v1. This allows dropping 2 of the 4 original patches and
makes the remaining patches quite small :)

Move the initialization of encoder variables a bit higher inside the
intel_dsi_init() function. So that can call intel_encoder_current_mode()
from intel_dsi_vbt_init().
This is a preparation patch for reading back the GOP configured pclk
from intel_dsi_vbt_init().
