Commit Message

Sripada, Radhakrishna Oct. 15, 2021, 9 p.m. UTC
The formulae has been updated to include more variables. Make
sure the code carries the same.

Bspec: 64631, 54023

v2: Make GEN11 follow the default route and fix calculation of
    maxdebw(RK)
v3: Fix div by zero on default case
    Correct indent for fallthrough(Jani)
v4: Fix div by zero on gen11.
v5: Fix 0 max_numchannels case
v6:
    - Split gen11/gen12 algorithms
    - Fix RKL deburst value
    - Fix difference b/ween ICL and TGL algorithms
    - Protect deinterleave from being 0
    - Warn when numchannels exceeds max_numchannels
    - Fix scaling of clk_max from different units
    - s/deinterleave/channelwidth/ in calculating peakbw
    - Fix off by one for num_planes TGL+
    - Fix SAGV check
v7: Fix div by zero error on gen11
v8: Even though the algorithm for gen11 says that we need to return
    derated bw for a qgv point whose planes are less than no of active
    planes, we return 0 for deratedbw when only one plane is allowed.
    We modify the algorithm to accommodate the case where no of active
    planes are same as the min no of planes supported by a qgv point.
v9: Fix dclk scaling for dg1

Replying to the right patch this time.
From what the bspec says, the changes look good.
Minor feedback below inline.

With that change,

The j here can be more descriptive to make it easy to understand. s/j/sagv probably?

I am not sure if this case warrants a departure from standard convention of naming iterators.
This iterator j is used in the current version of the code and I am skeptical about changing it.

Summary

FAILURE

Serious unknown changes coming with Patchwork_21357_full absolutely need to be
verified manually.

If you think the reported changes have nothing to do with the changes
introduced in Patchwork_21357_full, please notify your bug team to allow them
to document this new failure mode, which will reduce false positives in CI.

Possible new issues

Here are the unknown changes that may have been introduced in Patchwork_21357_full:
