any opinion about the cortex a35 over here ? I got curious about that core since st picked it for their stm32mp2
<Xogium>
is it really actually better than a7 in performance / power draw ?

Xogium: Highly likely it has better perf/w
<Xogium>
really ? Hmm I suppose due to smaller transistor size and such
<HdkR>
A7 is a frozen design, it doesn't really get the benefit of improving as time progresses :)
<Xogium>
oh so the a35 is still improving after 2015 ?
<Xogium>
yeah immages won't do it for me unfortunately :/ since I'm blind
<HdkR>
10% lower power and 6-40% higher performance
<HdkR>
plus 64-bit support
<Xogium>
compelling indeed
<Xogium>
I can see why st picked this if they want to keep things low power

Xogium: I think 64-bit is a huge selling point as well, regardless of whether that is a rational argument or not. At embeddedworld23 in Nürnberg, I noticed that everyone had replaced their imx6 and stm32 based boards with imx8 ones, and this was clearly based on customer demand
<arnd>
A large part of it is in fact rational, as being able to run 64-bit kenrels is a huge plus even if you run 32-bit userland
<Xogium>
yeah, true, there's that
<Xogium>
I don't think st did bad, I was just curious what that would mean for low power applications, since most aarch64 SoC these days seem rather power hungry
<arnd>
we are also getting to the point where even open source software is getting testing less on 32 bits, so running 64 bit means less engineering time to make things work, even for systems where 32-bit would do the job
<Xogium>
even for armv7 ? That's interesting
<arnd>
yes, I think armv7+neon is still much better supported than any other 32-bit target, but for newly written code there is a good chance that it has never been run on 32-bit anywhere, and is therefore buggy.
<Xogium>
that makes sense
<Xogium>
might get me one of these boards once they're out in the wild... I'm quite curious about them I have to say
<arnd>
the same way that nobody tests on big-endian, softfp or formerly popular ISAs (ppc32, mips, ...), so they end up running into stupid bugs
<javierm>
arnd: do you have a prediction in years for when 32-bit arm would more or less e-waste ?
<Xogium>
yeah... Too bad big endian makes more sense to me ;)
<arnd>
javierm: I think we'll see low-end SoCs based on single-core Cortex-A7 deployed to run Linux for at least another 5 to 10 years, and people running 32-bit Linux userland on Cortex-A510 (or similar) another decade after that
<javierm>
arnd: interesting, thanks for sharing your opinion
<Xogium>
I run my irc client on stm32mp1 ;)
<arnd>
javierm: the faster 32-bit chips have already all moved to 64-bit, which is moving down the stack, and the low-end 32-bit chips will just be considered microcontrollers and run simpler RTOS, though the hardware won't go away
<javierm>
arnd: that's what I was thinking too. That would just not run linux but considered micro-controllers
<arnd>
I think most of the arm9 chips you can still buy were originally sold as MPUs, but are not called MCUs
<arnd>
Not always the same product code, but often the same chip family, e.g. with the external memory bus replaced with a small in-package ram chip
<arnd>
the same happened across many other architectures, e.g. you can still buy ppc32 or superh MCUs that are similar to older SoC designs that could run Linux but are long discontinued
<geertu>
arnd: Renesas always considered the RZ/A series MCUs.
<geertu>
RZ/A1 and RZ/A2 have Cortex-A9, RZ/A3 has Cortex-A55
<geertu>
It's a pity they dropped the large on-chip RAM on RZ/A3

I am interested in helping out with support for snapdragon 8cx gen 3/Lenovo x13s platform. Does that get discussed here at all? Or is there somewhere else I should be looking?
