Here's another thing I tried which also may have made a difference. Gonna

Hi!
Follow-up on the v5 [1], things have gotten significantly
better in the last 9 months, thanks to the efforts on Bifrost
support by the Collabora team (and probably others I'm not
aware of).
I've been testing this series on a MT8183/kukui device, with a
chromeos-5.10 kernel [2], and got basic
This adds support for controlling panel backlights over eDP using VESA's
standard backlight control interface. Luckily, Nvidia was cool enough to
never come up with their own proprietary backlight control interface (at
least, not any that I or the laptop manufacturers I've talked to are aware
of),
Since we're about to implement eDP backlight support in nouveau using the
standard protocol from VESA, we might as well just take the code that's
already written for this and move it into a set of shared DRM helpers.
Note that these helpers are intended to handle DPCD related backlight
control
Noticed this while moving all of the VESA backlight code in i915 over to
DRM helpers: it would appear that we calculate the frequency value we want
to write to DP_EDP_BACKLIGHT_FREQ_SET twice even though this value never
actually changes during runtime. So, let's simplify things by just caching

This is the seventh version of the patch series. Change log:

* Rebase to the latest rdma-core master (commit a4885eda9addc4)
* Rerun kernel-headers/update against linux-rdma for-next so that the

v6:
Define a set of unit tests similar to regular MR tests and a set of
tests for send/recv and rdma traffic using dma-buf MRs. Add a utility

This function will be needed by the next patch where the driver
calculates the BW based on driver specific parameters, so export it.
At the same time sanitize the function params, passing the more natural
link rate instead of the encoding of the same rate.

TTM implements a rather extensive accounting of allocated memory.
There are two reasons for this:
1. It tries to block userspace allocating a huge number of very small
BOs without accounting for the kmalloced memory.
2. Make sure we don't over allocate and run into an OOM situation

Oh, my bad, I thought this was in drm_mode.h, but it's not. Then yeah
should be completely fine to fix it.

This still needs to be corrected.

The open-coded 64-bit division causes a link error on 32-bit
machines:
ERROR: modpost: "__udivdi3" [drivers/gpu/drm/amd/amdgpu/amdgpu.ko] undefined!
ERROR: modpost: "__divdi3" [drivers/gpu/drm/amd/amdgpu/amdgpu.ko] undefined!
Use the div_s64() to perform the division here.

I need a "real" name here, and in the signed-off-by: area as I do not
think you sign documents with a "." and "_", right?

Smatch found an uninitialized variable bug in this code:
drivers/gpu/drm/i915/gvt/cmd_parser.c:3191 intel_gvt_update_reg_whitelist()
error: uninitialized symbol 'ret'.
The first thing that Smatch complains about is that "ret" isn't set if
we don't enter the "for_each_engine(engine,
The devm_memremap() function never returns NULL, it returns error
pointers so the test needs to be fixed. Also we need to call
pci_release_regions() to avoid a memory leak.

Hello,
this patch set adds the support of the Lontium lt8912 MIPI to HDMI
bridge in the kernel.
It's only support the video part, not the audio part yet
since I don't have the datasheet of this component.
I get the current i2c configuration from Digi and
Boundary drivers.

Bump ?
