01:59 <tlwoerner> arnd: broonie: maybe something like this (but with more rows filled out): https://elinux.org/Armv8_Armv9_features

02:00 <tlwoerner> i assume if something is described as optional for armv8.0 and required for armv8.5 then it is also optional for armv8.1 - armv8.4 and required for armv8.6 and armv8.7

02:09 <HdkR> That assumption holds true

02:15 <HdkR> The ARM ARMv8 ARM, chapter A2 'Armv8-A Architecture Extensions', lays all this out by version in a fairly easy to read form. Should be easier to update that spreadsheet with all the new things

02:17 <tlwoerner> HdkR: lol, that's where i'm getting the info from :-)

02:17 <HdkR> :)

02:18 <HdkR> ARM has some web pages somewhere for which feature corresponds to which ARMv9.x level. Since we don't have a manual for that yet

02:18 <tlwoerner> but the place where i'm getting this from, section A2.2.1 says "_additional_ functionality…" so i'm not sure where the _base_ functionality is found

02:18 <tlwoerner> HdkR: ooh, if you have a link that'd be awesome :-)

02:20 <HdkR> https://developer.arm.com/architectures/cpu-architecture/a-profile?_ga=2.16133302.1278903384.1617133127-1189840679.1598782639

02:21 <HdkR> Bit more annoying to parse since you can't tell optional versus rquired and have to make guesses

02:22 <HdkR> https://developer.arm.com/documentation/ddi0608/latest Supplemental manual has a bit more

11:30 <broonie> tlwoerner: I was more thinking for SoCs but yeah

12:39 <tlwoerner> broonie: yes, i like that idea too, but i think it'd make one table too big. i can create a new table/page for SoCs

22:27 <arnd> tlwoerner: I wonder we could collect that information semi-automatically from users running a small shell script, e.g. something that takes the 'lscpu -J' output and submits it to a google sheets spreadsheet as a row

23:20 <Ntemis> hi

23:21 <Ntemis> I need some help/info on amlogic S812

23:22 <Ntemis> Can S812 use neon fpu or only up to vfpv3?

23:38 <HdkR> Ntemis: That'll have NEON

23:39 <Ntemis> amazing news HdkR thank you
