<arnd> palmer: regarding the fdpic patch: merging this through your tree definitely makes sense, and it would be good to have since riscv is now the only architecture with support for !MMU but no fdpic, after it was added in xtensa
<arnd> two other concerns about it:
<arnd> there is a good chance you need the same fix as 9c2cc74fb31ec ("xtensa: fix signal delivery to FDPIC process"). I don't know what that does exactly, but all the other ones seem to have it
billchenchina- has joined #riscv
<arnd> second, are there actual users still on k210? my feeling was that interest in that disappeared mostly after proper usable hardware became available, and it's been several years now
billchenchina has quit [Ping timeout: 240 seconds]
<arnd> for reference, I think we added fdpic support in arch/arm/ in 2017, which coincidentally was the same year that everyone on arm stopped their linux-nommu projects, so I still haven't heard of anyone actually shipping fdpic userland, despite it all being there

<geertu> conchuod: What are the possible wake-up sources for icicle? Ethernet does not seem to support Wake-on-LAN
<geertu> On starlight, WoL after s2idle works. WoL after s2ram doesn't, but that might be a firmware issue?
billchenchina has joined #riscv
<conchuod> geertu: The only think I recall testing s2i with was the RTC.

<Esmil> lol bigwig. i don't know about that..
<Esmil> i just fixed the easiest of the #ifdef CONFIG_SOC_SOPHGO hacks :)
<pierce> Not sure how that convo in matrix relates to the pull request...
<Esmil> heh, it doesn't. that conversation was about their LinuxBoot not caring about the device tree specified in extlinux/extlinux.conf
<Esmil> it just always passes the device tree their "zsbl" loads from riscv64/mango-milkv-pioneer.dtb to the kexec'd kernel

<pierce> Yeah I was reading the convo as messages were coming through, I think Daniel would be a good person to fix up their stuff due to his oreboot experience with other SoCs/SBCs
<Esmil> yeah, does he have a box/board to play with though?

<sorear> i have to look at the fdpic thing, i was not happy with the last fdpic patchset on an ABI level

<jedix> looks like nommu kernel work is going on for riscv 64?
<geertu> also for rv32
crabbedhaloablut has joined #riscv
<palmer> sorear: if you have fdpic issues can you post them on LKML? It's not really my thing, but if we end up with code getting merged then we'll have a defacto ABI and it'd suck to have a bad one
<palmer> arnd: I have no idea if anyone's concretely using it, but Damien keeps testing stuff when I ask and sometimes we get bug reports. One of the Plumbers talk suggestions is about deprecating stuff, but so far everything I've come up with as a deprecation candidate has a user...
<arnd> geertu: do you know which rv32 platform that would be for?
<palmer> the !MMU stuff? I think it was hobbyist stuff, I just merged it because it's almost no code

<courmisch> Linux sounds quite horribly bloated to run on noMMU devices

<sorear> palmer: is this going to be an issue this week? Trying to prioritize
<palmer> sorear: I currently don't have anything to prevent the merge, but if you think there's an issue at least just having a post saying a maybe would be ideal -- that way folks know what's up. I'm not in any specific rush for the patches
<palmer> so even just a "we need to make sure we don't screw up $PROBLEM" would be great, maybe that's enough to get someone else to look

<courmisch> meh, why use perl to generate asm when you can use the assembler?

<gurki> courmisch: why not use bash to generate batch to generate powershell to (...) ?
<gurki> scnr
<courmisch> well, yes... why?
