[PATCH 0/4] drm/i915/bw: Split bandwidth params into platform- and display-IP-specific structs

[PATCH 0/4] drm/i915/bw: Split bandwidth params into platform- and display-IP-specific structs

[Gustavo Sousa]

Some of the parameters of used in display bandwidth calculations are
tied to the platform and are orthogonal to the display IP.  After talking
with the hardware team, we now have the information (and Bspec has been
updated) that the members deprogbwlimit and derating of struct
intel_sa_info are such platform-specific ones.

With that, we are now able to make the driver code more aligned with the
hardware by splitting structs intel_sa_info into two different structs:
one that is platform-specific and another that is display-IP-specific.

That change also allows us to simplify how we select the parameters for
the calculation.

[PATCH 1/4] drm/i915/bw: Extract platform-specific parameters

[Gustavo Sousa]

We got confirmation from the hardware team that the bandwidth parameters
deprogbwlimit and derating are platform-specific and not tied to the
display IP.  As such, let's make sure that we use platform checks for
those.

The rest of the members of struct intel_sa_info are tied to the display
IP and we will deal with them as a follow-up.

[PATCH 2/4] drm/i915/bw: Deduplicate intel_sa_info instances

[Gustavo Sousa]

Now that intel_sa_info contains bandwidth parameters specific to the
display IP, we can drop many duplicates and reuse from previous
releases.

Let's do that and also simplify intel_bw_init_hw() while at it.

[PATCH 4/4] drm/i915/bw: Extract get_display_bw_params()

[Gustavo Sousa]

Just like it is done for the platform-specific bandwidth parameters, use
a separate function named get_display_bw_params() to return the display
IP-specific parameters.  This simplifies intel_bw_init_hw() by having
just one call for each of *_get_info() function.

In the above, "plat" feels like tautology, since they're all prefixed by
platform acronyms.

What's the point of assigning and returning ret?

Why not just return &icl_plat_bw_params; directly?

I don't understand at all why the function is written the way it
is. Seems like it should be a regular if-ladder like we have, with zero
gotos.

Perhaps it would be better to pass this in instead of every function
having the call.

Nitpick, "plat" is not an abbreviation I'm fond of.

So if these are tied to IP, why are they still named after platforms?

Nitpick, you'll never see me use "disp" abbreviation. It just doesn't
abbreviate enough, only makes stuff harder to read.

I would pass both of these in as parameters, with centralized
assignment, and not have every single function call the getters.

Yeah, true.  In an upcoming patch I also introduce display-IP-specific
structs, and I decided to use plat vs disp to differentiate
(e.g. tgl_plat_bw_params vs tgl_disp_bw_params).

Any suggestion of how to make it better?

I would like that we always have a default to be returned if somehow we
miss adding a new case for a new platform (hence the "missing:"
label).  The idea of assigning to ret is for it to have a valid value
when hitting the missing: point.

Arguably we could also only use this pattern only in the last case, but that
would feel like an inconsistency and prone to someone forgetting to
"push" it to the next new platform when the time comes.

I would be much happier with a switch-case statement that would have a
"default:" combined with "fallthrough", but I think that's not possible
with the current way we handle platform matching in the display code.

Just wanted the default for the missing case to be the most recent
platform in an "automated" way, with separate ordering for dgfx and
integrated.

Do you suggest we do not have such a default and cause a null-pointer
deref (on purpose) if we forget to add a new platform?

Or always "manually" update the default when we add a new
platform-specific instance?

Okay. I think I'll have to rework patch #4 as well
then :-)

Noted. 

Out of curiosity: because it is a noun of its own? Or is it something
else?

Decided to use xelpdp for the one above and platform names for the other
ones because xelpdp is where we trully have IP disaggregation.

That said, I could try to use IP release names for the other ones as
well. So, something like below?

s/tgl_disp_bw_params/xe_d_bw_params/
s/rkl_disp_bw_params/xe_d_rkl_bw_params/
s/xelpdp_disp_bw_params/xe_lpdp_bw_params/

And what to do with icl_disp_bw_params? Do we have a suitable display
release name for it?

"soc" might be more consistent with what we (and various hardware docs)
do to refer to "stuff that's outside the graphics/media/display IP and
doesn't relate to GMD_ID version numbers."  Technically "soc" is a bit
of a misnomer too since a lot of our recent platforms are multi-chip and
not truly SoC's anymore, but the intent is still understandable.

It looks like the intent might have been to let people keep copy/pasting
the same pattern and have the fallback at the end always default back to
whatever the "newest" one was if a proper match wasn't found.  But I
agree that the handling here feels awkward and a simple if/else ladder
would be preferable.

It seems strange to need to need to drop back to a platform check here
on something that's supposed to be tied to IP version.  But if I recall
correctly, RKL was a bit of a strange frankenstein platform where TGL's
"gen12" IP got backported onto an ICL-style chassis, which caused it to
inherit various ICL traits despite the new IP.  It might actually be
more clear to just re-use the icl_sa_info for that one and leave a
comment admitting that yeah, RKL was an oddball platform that didn't
really follow the rules.

We might also want to rename tgl_sa_info to "gen12_sa_info" since that's
a more accurate description (and is the last version where we're allowed
to use the "gen" terminology rather than the new marketing names for the
IP).  By similar logic, "icl_sa_info" should become "gen11_sa_info"
since it does indeed get used on the other gen11 platforms too
(jsl/ehl).

Although we're not allowed to use "gen" terminology with newer IPs,
"gen12" and earlier are grandfathered in and still okay to use since
they existed and were in widespread public use when the new rules came
down.  So we should use gen11 and gen12 in place of ICL and TGL here.

As noted on the previous patch, RKL was a weird exception to all the
rules and I'd be okay explicitly forcing it to use the "gen11"
structures even though it's officially got IP version 12 since it kind
of makes sense from how they frankensteined that platform together at
the hardware level.

Yeah. I intetionally prefered to use "platform" as a general term to
refer to either SoC or multi-chip package.  Do you prefer that we name
the struct type intel_soc_bw_params?

What about intel_display_bw_params that is added later? Is that a good
name? I thought intel_ip_bw_params would be a bit vague, since we have
different types of IPs (display being one of them) in the platform.

Yeah, allowing developers to easily add new platforms without too much
churn was the intention here.  I knew this style was unconventional, but
I thought the intent justified it (and IMO the code is still readable,
although admittedly a bit weird).

If that's not acceptable, would something along the lines of below be
accepted?

    if (display->platformOB.dgfx) {
        if (...)
             return platform_a_params;
        else if (...)
             return platform_b_params;
        else if (...)
             return platform_c_params;
        
        default_params = platform_c_params;
    } else {
        if (...)
             return platform_d_params;
        else if (...)
             return platform_e_params;
        else if (...)
             return platform_f_params;
        
        default_params = platform_f_params;
    }
    
    do_warning();
    return default_params;

Huh.  Yep, using icl_sa_info sounds good; I totally missed the fact that
rkl_sa_info matched icl_sa_info.

Sounds good.  Since I'm renaming the struct type name to
intel_display_bw_params (to indicate that those are tied to the display
IP) in a separate patch, I think it makes sense to do the instances
renaming there as well.  Ack on moving back to mtl_sa_info here and then
doing all renaming in the patch that also renames the struct type?

Personally I think "soc_bw_params" vs "display_bw_params" seems like a
similar distinction to what we have elsewhere in the driver (especially
if we add a 1-sentence comment above the structure clarifying what the
origin/source of those parameters is.  But I'll leave it up to Jani and
the other display experts to make the call since they're the ones who
work with this code the most.

Yeah, I think a traditional if/else ladder like this is best.  I don't
think we even need to track a 'default_params' variable; we can just
directly return some recent platform as a fallback at the end too.  If
the fallback winds up not getting updated when we add new platforms, I
don't think that really matters since there's no real guarantee that
falling back to incorrect n-1 platform numbers is better than falling
back to incorrect n-2 platform numbers.

If we've screwed up and forgotten to add the parameters for a new
platform, then that's going to be something that's flagged almost
immediately by CI and will be quickly fixed long before the platform
ever leaves force_probe.

Yeah, doing all the renames in a dedicated patch sounds fine to me.

Well, I would like to make a distinction between client and discrete
(e.g. there is a significant difference between BMG's and
PTL's derating param).  That would be the reason for the default_params
variable, which would allow a single place to raise the warning.

Yeah, true.  Another possibility is to just return NULL and purposefully
cause anull-pointer dereference; or even have the default being all
zeros, so that we don't worry about updating the default from time to
time.
