At legacy chipsets, it required DPU_PINGPONG_DSC bit be set to indicate
pingpong ops functions are required to complete DSC data path setup if
this chipset has DSC hardware block presented. This patch add
DPU_PINGPONG_DSC bit to both PP_BLK and PP_BLK_TE marcos if it has DSC
hardware block presented.

PP_BLK_TE is no longer there.

marcos -> macros.

I may have not made this clear, but the comments on patch 2/7
(introducing the DPU_PINGPONG_DSC bit) also apply to this patch: clarify
DPU 7.0.0 exactly in favour of "legacy", which has no definition at all
and changes over time.

Strictly speaking this patch together with 2/7 is not bisectable, as 2/7
first disables the callbacks for _all_ hardware and then this patch adds
it back by adding the flag to all DPU < 7.0.0 catalog descriptions.

To solve that, as we do in other DPU patch-series, just squash this
patch into 2/7.  That way you also don't have to spend extra time
rewording this commit message either to match the improvements we made
in 2/7 (for example, you mention that "ops functions are required to
complete DSC data path setup", but those were already available before
2/7, despite sounding as if this is a new thing that was previously
missing entirely).

But please wait at least a couple days before sending v6.  I only have a
few hours every day/week but would appreciate to review and test all the
other patches.

This should be added to the MASK (add new #define's where necessary).

I asked to split these into two patches, but I see your point and
partially agree with it. However if we mix the catalog changes with
functional changes, it is too easy to overlook or misjudge the
functional changes.

As you are correct about bisectability, I'd probably suggest either

I did the same in the INTF TE series for patches that have very little
and/or very obvious functional changes: exactly this combination of
guarding a few callbacks behind a feature bit, and setting that feature
bit on a few specific catalog entries.

Sure, if you really prefer a split I'd go for two patches:
1. Add the flag to the enum and catalog;
2. Add the ops guard (functional change).

Then don't forget to reword the commit message, following the guidelines
below and the suggestion for 2/7.

Plan sounds good to me.

Marijn, we will wait for a couple of days to post the next rev but would 
be hard more than that as we need to pick up other things which are 
pending on top of this. Hence would appreciate if you can finish reviews 
by then.

It depends on how many more revisions are needed after that, and not all
patches in this series have an r-b just yet.  Given the amount of review
comments that are still trickling in (also on patches that already have
maintainer r-b) I don't think we're quite there to start thinging about
picking this up in drm-msm just yet.  I doubt anyone wants a repeat of
the original DSC series, which went through many review rounds yet still
required multiple series of bugfixes (some of which were pointed out and
ignored in review) to be brought to a working state.  But the split
across topics per series already makes this a lot less likely, many
thanks for that.

In other words, let's take it slow and do things properly this time. And
who knows, perhaps the rest of these patches are more straightforward.

I think the outstanding comments shouldnt last more than 1-2 revs more 
on this one as its mostly due to multiple patches on the list touching 
catalog at the same time. I have been monitoring the comments closely 
even though I dont respond to all of them.

One of the major reasons of the number of issues with DSC 1.1 was QC 
didn't really have the devices or panels to support it. Thats why I 
changed that this time around to take more control of validation of DSC 
1.2 and ofcourse decided to break up of series into the least amount of 
functionality needed to keep the DPU driver intact.

All that being said, we still value your comments and would gladly wait 
for a couple of days like I already wrote. But there are more 
incremental series on top of this:

-> DSI changes for DSC 1.2
-> proper teardown for DSC
-> DSC pair allocation support
-> DSC 1.2 over DP

We will be posting all of these within next couple of weeks on top of this.

Ack. the intent is always to do things right the first time.

I'd say, it's fine to post them now, as we have more or less agreed on 
the helper series. The interface between the series should be stable then.

The RM series is probably the one having bigger dependencies/conflicts 
on other pending patches (include virtual wide planes)

1 is already posted, will keep fixing review comments
2 will be posted pretty soon

DSC1.2 over DSI will be complete with this set.

I will finish up virtual planes review by early next week. Already 
underway ...

3 & 4 will be posted soon after that.

Really glad that you are able to test and validate it now, that goes a
long way.  Does that also mean you can post the panel patches quickly,
so that everyone has a point of reference?  As you said that is one of
the main points where DSC 1.1 "went wrong" (a misunderstanding of
drm_dsc_config).

Yeah, I'm familiar with the concept of having many dependent series, and
now DSC series are even rebasing on DPU (catalog) cleanups to preempt
conflicts, which is really hard to follow.
Dmitry just pushed v5 of "drm/i915/dsc: change DSC param tables to
follow the DSC model" [1] and seems to have dropped some patches that
some of these series are depending on, resulting in compilation
failures.  Other series don't seem to fully mention all their
dependencies.

So, for this to go as convenient as possible, do you have a list of
series, in a desired order that they should be reviewed and tested?
That way I can direct my priorities and help achieve the goal of picking
base dependencies as early as possible.

For example, one of the many series regresses DSC on the Xperia XZ3
(SDM845), but I have yet to bisect and understand which patch it is.
Will let you know as soon as I get my tree in order.

Hi all,

Just want to add to this list of series -- I'm planning to post the 
r66451 panel driver + dts changes next week after I post the v2 of DSI 
for DSC v1.2.

Thanks,

We'd have to pick them into our code or submit directly to drm-misc. I 
removed the patches which we can get in w/o Intel review.
