Data width for dsc engine is aligned with pipe, not with whole screen

The dsc width is not related to the timing with back front porch in

Hi Laurent,
Do you plan to add an API to get and parse EDID to mode list?
video mode is tightly coupled with panel that is capable of hot-plug.
Or you are busy on modifying EDID parsing code for sharing it amoung
DRM/FB/etc? I see you mentioned this in Mar. It is great if you are
considering ad
Is there any discussion on HDCP on the summit? It is tightly
coupled with HDMI and DVI and should be managed together with the
transmitter. But there is not code to handle HDCP in DRM/FB/V4L in
latest kernel. Any thoughts on HDCP? Or you guys think there is risk
to support it in kernel? Thanks
Hi Laurent,
Do you plan to add an API to get and parse EDID to mode list?
video mode is tightly coupled with panel that is capable of hot-plug.
Or you are busy on modifying EDID parsing code for sharing it amoung
DRM/FB/etc? I see you mentioned this in Mar. It is great if you are
considering ad
Is there any discussion on HDCP on the summit? It is tightly
coupled with HDMI and DVI and should be managed together with the
transmitter. But there is not code to handle HDCP in DRM/FB/V4L in
latest kernel. Any thoughts on HDCP? Or you guys think there is risk
to support it in kernel? Thanks
If DSC is enabled, the only case is with 2 DSC engines so far. More
usage case will be added, such as 4 DSC in 4:4:2 topoplogy.
So get real number of DSCs to decide whether DSC merge is needed.

DSC is
not aligned with maximum pipes.
Thus we support DSC flexiblely with this patch set with storing
the number and configuring DSC with it.

drm/msm/dpu: Do not fix number of DSC
drm/msm/dpu: configure DSC per number in use
drivers/gpu/drm
Only 2 DSC engines are allowed, or no DSC is involved currently.
We need 4 DSC in quad-pipe topology in future. So let's only configure
DSC engines in use, instread of maximum number of DSC engines.
