  Some resource limits on IPA v3.1 and v3.5.1 have their max values set to
255, this causes a few splats in ipa_reg_encode and prevents it from booting.
The limits are all 6 bits wide so adjust the max values to 63.

Thank you for sending this Caleb.

On IPA v3.5.1 (SDM845) I confirm that these resource limit fields are
6 bits wide, while the values we assign are in some cases 255, which
cannot be represented in 6 bits.  Your fix in this case is proper,
changing the maximum limit from 255 to be 63.  (Just in case, I've
sent a note to Qualcomm to ask them to confirm this, but I think this
is fine.)

I re-checked the definitions of the MIN_LIMIT and MAX_LIMIT fields
for IPA v3.1, and it turns out in that case the *register field*
definitions were wrong.  They should, in fact, be 8 bits wide rather
than just 6.  So in that case, 255 would be a reasonable limit value.

Did you observe these splats when doing actual testing on an msm8998
(which has IPA v3.1)?  Or did you just double-check the code?  I
looked at the other currently-supported platforms and didn't see
this sort of problem elsewhere (IPA v4.2, 4.5, 4.9, 4.11).


Could you please send a new version of your patch, which fixes the
register definition in "ipa_reg-v3.1.c" instead?

It might be best to fix the two issues in separate patches, since
they will parts pf the code with different development histories.

Thanks!

Heh, well that's fun... Thanks for checking

I found these just by 'grep'ing for "max = 255", none of the other versions had 
that and I didn't see anything obvious at a glance so I expect only these two 
platforms are affected. The same issue has been confirmed on MSM8998: 
https://gitlab.com/msm8998-mainline/linux/-/issues/39

Jami (CC'd) has offered to test the next revision of the fix there so we can be 
sure it works on v3.1 and v3.5.1.

That makes sense, will do.
