Ya, sorry, I'm skipping everything for the conference -- I'm still on baby duty in the mornings...
<palmer>
I didn't even realize it was 7, I haven't looked at a clock all morning ;)

palmer: thank you! I found that commit too, but I don't understand why THP needs RWX to be zeroed. Help?
<JohnHenry>
Is it just for convenience where masking off the first 5 bits is easier?
<JohnHenry>
I recognize that the leaf page property of the RWX bits is important even when a page is swapped, but that seems like an argument to keep them set instead of zeroing them?

Hi all

i am new to RISC-V, have bought a Milk-V Jupiter as my first board, should have it early next week. Does anyone here have this board ?
<Tenkawa>
I have BananaPi's version of that SoC but not the Mars one
<Tenkawa>
er Milk-V
<Tenkawa>
Its definitely a bit different..
<Tenkawa>
did you buy the K1 or the M1?
<Tenkawa>
I have K1
<Tenkawa>
er a
<mfny>
i looked at the banana pi board but wanted something i could put in a regular case
<Tenkawa>
You will want a stout power supply... that I can tell you..
<Tenkawa>
Even with my board just running a single NVMe drive it needs steady power
<mfny>
im going to be using a MATX case and a regular 550w ATX PSU
<mps>
hm, Milk-V Jupiter looks like bananapi F3 'on steroids'
<Tenkawa>
mps: basicly yeah
<Tenkawa>
I would've waited and got it if I would've known it was coming
<mps>
what is this Soc 'SPACEMIT K1/M1', i.e. what is M1
<Tenkawa>
mps: just a matx version
<mps>
ah
<Tenkawa>
higher ram
<Tenkawa>
since its bigger they can throw more chips on ir
<Tenkawa>
er it
<mps>
but afaik 'normal' K1 supports 16GB RAM
<mfny>
Jupiter M1 is 1.8Ghz vs the K1 1.6GB also 16GB RAM
<Tenkawa>
I hadn't seen any yet in physical boards for the K1 "boards"
<mfny>
i went for the M1 as it was not that much more expensive then the 8GB K1
<Tenkawa>
The F3 seems like it "might" be able to fit but it still looks a bit small
<mfny>
few more megahertz and a bit more ram for not that much more
<mps>
iirc ncopa have BPI F3 with 16GB RAM
<Tenkawa>
hmm interesting.. I wonder if they rereleased it
<mps>
maybe I'm wrong, though
<Tenkawa>
they weren't making any originally (even mine is only 4gb .. (thats all they offered))
<mps>
ncopa uses it as CI machine for alpine
<Tenkawa>
I bought from the first rev though
<mps>
hah, my have only 2GB RAM
<Tenkawa>
yeah.. I was "not" going to get that one
<Tenkawa>
I saw that box and clicked off it asap
<mps>
I've got it for free, so I don't cry :)
<Tenkawa>
lucky :)

I'm doing BSD stuff now so next to nothing runs on risc-v so I'm working on arm for now.
<mps>
Tenkawa: doesn't openBSD run on visionfive V2
ganboing has quit [Remote host closed the connection]
<Tenkawa>
FreeBSD does too.. but thats the only board
<Tenkawa>
I've got 5 diff boards
<Tenkawa>
I'm running BSD on 2 diff ARM64 high speed boards already.. going to start RV work soon.
<Tenkawa>
just needed to reacclaimate myself after years of rustyness
<mps>
afaik BSD works on a lot of arm64 things, but I tested only on apple silicon
<Tenkawa>
mps: depends on BSD variant... I prefer FreeBSD though
<mps>
now I'm interested only on riscv mostly, and loongarch to some degree
<Tenkawa>
Nod.
<mps>
Tenkawa: btw, someone is trying to upstream u-boot patches for bananapi F3
<mps>
I helped a little
<mps>
mostly by advises and testing something
<Tenkawa>
Excellent.. that would solve a lot of forward movement... thank you... keep me aprised when it makes it in and I'll start pulling and building
<mfny>
im a bit worried that i bought the wrong board as a RISCV newbie tbh
<Tenkawa>
We can move our builder to pull those and try to build u-boot
<Tenkawa>
And do some testing
<mps>
Tenkawa: I already did, but it doesn't have FSBL yet, only main u-boot and it worked in my tests
<Tenkawa>
Oh ok..
<Tenkawa>
Do you see any change in the remoteproc cpu spin with it?
<mps>
but this 'someone' (I don't know real name) work these days on adding rest to mainline u-boot
<mps>
I bet it also can boot on lpi3a
<Tenkawa>
I'm only working on these boards really atm.. Rock5, RPI5, Visionfive2, Mars CM, BPI-F3, Star64 so that all should keep me busy
* mps
sorry why he didn't made bare metal forth for riscv and forget all these kernels, patches and what not

ive ordered a cooler with the jupiter, one of those small 40mm fan ones, will i need some TIM or a thermal pad on the CPU before mounting the cooler do you think ?
<mps>
nowadays cooler usually have thermal 'film' but also thermal paste could be used if it doesn't have 'film' (not sure how it called properly)
<Tenkawa>
you should always use some sort of "buffer" if it doesn't come with one....as mps said though it should have one (that board likely will have a big heatsink with it)
<Tenkawa>
mine did at least
<Tenkawa>
you definiteky do not wan't the heatsink/fan just sitting against the chip though
<Tenkawa>
s/definiteky/definitely
<mps>
I've got cooler with VF2 and VF1 with this 'thing' and simply put them, works fine
<Tenkawa>
mps: yeah... just three heatsinks (soc, nvme, and lan controller here)
<Tenkawa>
the eth sometimes can get a bit warm depending on use
<mfny>
Tenkawa,: it does not come with a cooler have to buy separetely
<Tenkawa>
Still trying to reacclaimate myself before I jump in RV
<mps>
I'm thinking to throw linux and use openBSD
<Tenkawa>
I like Ubuntu with mainline on it though lol
<Tenkawa>
(only board it works right currently)
<mps>
and also thinking to throw linux from apple silicon and use openBSD on it
impomatic has quit [Quit: Client closed]
<Tenkawa>
That I would "not" do
<Tenkawa>
OpenBSD's hardware support is much too lacking
<Tenkawa>
especially for my ui machine
<mps>
Tenkawa: I already have it on external ssd disk and boot sometimes on m1pro
<mps>
but I have to relearn BSD
<Tenkawa>
Which vid server is it running nowadays?
<Tenkawa>
is it still x11?
<Tenkawa>
or have they moved to wayland yet?
<mps>
yes, afaik BSD use only x11
<Tenkawa>
Yeah that would be horridly slow on sotfware rendered mbp
<mps>
I doubt BSD ever will move to wayland
<mps>
m1 was fine n linux simpledrm
<Tenkawa>
yeah... drm...
<Tenkawa>
you wont get that on bsd
<mps>
I don't use 'heavy' gui apps
<Tenkawa>
it will be pure software.. no direct to hardware
<mps>
firefox and mpv worked fine
<Tenkawa>
I use much heavier apps I guess... I can't give those up
<Tenkawa>
lol
<mps>
someone on #asahi channel told will write gpu driver for BSD
<Tenkawa>
well that would work...
<Tenkawa>
(depending on "which" bsd)
<mps>
words were about openBSD
<Tenkawa>
nice.

Tenkawa: dont happen to know how big the K1 is on that banana pic board do you (for sizing of thermal pad)
<mfny>
would say 10mm x 10mm work maybe ?
<Tenkawa>
if its a standard K1 proc its .. (just a sec)
<mfny>
m1 has a larger package but it should not be to much larger
<mps>
I didn't put these passive coolers on my BPI F3 and it works quite fine, though I don't run intensive task on it
theChn has quit [Quit: Leaving]
<Tenkawa>
yeah I dont run a fan
<Tenkawa>
I use heatsinks and never go over 45C
<Tenkawa>
and I put it through a lot
<Tenkawa>
(still trying to find size on this fan... none if the sites have it listed. just pics)
<mfny>
not looking for the size of the fan but looking for the size of the chip package
<mfny>
so i can work out what size thermal pad to order
<mfny>
tho i guess i could always cut to size
<Tenkawa>
Its the same size soc on all of them
<Tenkawa>
its a Spacemit-K1
<Tenkawa>
thats universal
<Tenkawa>
thereThe K1 media size is 10mm x 7mm.
<jbe>
ah, right, thermal pads. I read somewhere that the radxa rock pi 5b cooler would fit on the milkv jupiter, and fair enough, it does seem to. the heat pads are oriented the wrong way though so I'd need to get new ones. meanwhile I'll probably just see how well it goes without
<Tenkawa>
found it
<mfny>
yeah but i cant find that info anyware, the size of the package that is
sakman has quit [Quit: Leaving]
<mfny>
oh ok
<mfny>
jbe: you have a Jupiter ?
<jbe>
mfny: yeah, I haven't had the time to do much more than unbox it yet though
<mfny>
jbe: i have one on the way also case etc for it to
<jbe>
yeah, same for me, I'll be putting it in a rack case I have lying around, then I guess hopefully have time to play around with it a bit
<mfny>
jbe: oh is that the base of that cooler i bought to ?
<Tenkawa>
jbe: I built my own rack for 4 boards initially
<jbe>
Tenkawa: ah, cool, for me I just had some spare equipment to repurpose :)
honeydatax has joined #riscv
<Tenkawa>
jbe: I carried these around with me and was tired of having to recable/prep them so I built a mini-rack that I could just throw in my gear bag and go
<Tenkawa>
When I get to a destination I pull out the rack and a bench power supply I have.... plug the power cables up... and go...
gioyik has quit [Remote host closed the connection]
<Tenkawa>
(the power cables are still too annoying to leave plugged in.. so I pull them off when I pack up)
gioyik has joined #riscv
<jbe>
you use the 12v input?
<Tenkawa>
some are 5, 9 and 12.. thats why I use a bench supply
<Tenkawa>
It does multiple voltage outputs so I have everything I need.. (I have 3 of them if needed... 360 watts total if needed)
<jbe>
sounds like a neat setup indeed
<Tenkawa>
Fortunately everything I do is headless so power is usally the least of my problems
<Tenkawa>
heheh
<Tenkawa>
Networking and disk io are my biggest fights
<Tenkawa>
I primarily use wifi for flexibility and lower cabling..
