Is there any way to find interrupt mapping for context bank which is disabled/unused on qcom "B familly" SoC?
<aka_[m]>
obv TRM might have that but random person is out of luck in such scenario.
<Mis012[m]>
well, there is no TRM for anything other than 8916
<Mis012[m]>
there are just onobtainium docs
<bamse>
aka_[m]: the downstream sources are typically what you're forced to use for inspiration for that...
<Mis012[m]>
and NDA docs, but I doubt those will have it
<bamse>
aka_[m]: but what are you specifically looking for?
<bamse>
Mis012[m]: i don't think i've seen that information in those :/
<aka_[m]>
bamse: well thing is there is 8953 TZ impl for arm-smmu-v2 and i wanted to test if it will work on 8976, for that i need to list of interrupts and they map 1:1 with banks.
<aka_[m]>
Some of banks are not described so they also lack interrupts so in result i cannot even try it.
<Mis012[m]>
bamse: yeah, they're not meant for people writing SoC drivers, unlike TRM and HPG or whatchmacallit
<aka_[m]>
there is great spreadsheet for that by Angelo
<bamse>
aka_[m]: ahh, so in particular it's the list of interrupt you need...rather than the context bank configuration...
<aka_[m]>
however last 3 banks.....
<aka_[m]>
same goes for gpu iommu.
<aka_[m]>
Before it somehow worked with qcom_iommu but still it needs some patches i think.

<jhugo____>
aka_[m]: You wouldn't happen to have a list for 8956? Our internal documentation says its the same chip as 8976
<Mis012[m]>
jhugo____: well, if it's not used on downstream, then the only other list (unless 8916) is your internal documentation :P
<jhugo____>
I might have been released :) Would need to know exactly what I'm looking for though
<Mis012[m]>
jhugo____: I can't speak for aka_, but I'm personally looking for interrupt numbers for the SSC BLSP QUPs on msm8998
<Mis012[m]>
(as going to the APSS)
<Mis012[m]>
I might have the BLSP irq number (didn't test it yet) because it was randomly mentioned in some TZ xml with "but we use polling anyway" next to it
