<tlwoerner>
a couple months back, someone here was going to take a look at adding cpu therm support for the rk3308. did that get off the ground?

tlwoerner: I only have a local branch or worktree with some code copied from vendor kernel I used for testing thermal on rk3308, I can push to a branch later, someone else can hopefully upstream proper code :-)
<tlwoerner>
strange. all the other tables have an entry for -25 (and don't seem to be missing any multiple-of-5 entries)
<tlwoerner>
i wonder what the first entry in each table does. seems to be something that isn't in the table
<tlwoerner>
the first and last entries are different than the rest
<tlwoerner>
qschulz: okay thanks for clarifying, good to know
robmur01 has quit [Remote host closed the connection]
<qschulz>
tlwoerner: don't know if it's on purpose that -25 is omitted
<qschulz>
tlwoerner: it seems like there's a linear extrapolation to figure out the approximate value
<qschulz>
so you have 0 as lower value even if it's not in the table, and max value above highest value in table
<tlwoerner>
yes, the TRMs say to interpolate linearly between values, so i assume that's what the kernel is doing
<qschulz>
but with the same value, so that it simplifies the checks we do
<qschulz>
and we don't have to check whether we are below the min or above the max value in the table
<qschulz>
you just extrapolate
* qschulz
shrugs
<qschulz>
I think it's worth sending a patch for the -25 :)
* tlwoerner
grumbles.... friggin' upstream-status tag
<dsimic>
qschulz: (re: the base DTB doesn't get rebuilt twice, it gets the -@ flag) yes, that's what actually happens
<dsimic>
I'll respond in both the v4 and v5 a bit later
<dsimic>
Kwiboo: I tryly wonder how do you manage to both have a completely opposite day job and contribute so much to U-Boot and DT stuff
<dsimic>
ah, I see qschulz was already baffled with it... me too
<tlwoerner>
qschulz: ok, i can send a patch (woo!)
<qschulz>
dsimic: :( what is there to answer to v5
<dsimic>
regarding days at the dayjob being exciting or not... there's huge difference between something being exciting and having something you _need_ to do as your job description, daily tasks, etc.
<dsimic>
tlwoerner: (re: adding cpu therm support for the rk3308) it was me, and I'm still committed to it, but I'm primarily waiting for sample board(s)
<dsimic>
I can't afford buying them myself, so I asked Radxa, but that didn't go extremely well... we'll see, though
<tlwoerner>
dsimic: okay. just wanted to make sure i didn't miss it
<dsimic>
qschulz: I haven't gone thrugh the v5 yet, actually
<dsimic>
and I need to test a few things
<dsimic>
tlwoerner: did I get it right that you'll handle the RK3308 thermal stuff?
<dsimic>
s/thrugh/through/
<tlwoerner>
dsimic: i'm testing the patch Kwiboo pointed to
<dsimic>
ah, I see... so, I'll keep asking Radxa about the sample boards
<dsimic>
just pinger Radxa, so we'll see

Kwiboo: your rk3308 therm patch works for me on the rock-pi-s
naoki has quit [Quit: naoki]
<tlwoerner>
i've got 7/13 devices around the farm that are rock-pi-s, it'd be nice to collect/record SoC therm data for these too :-)

Kwiboo: is there any reason you can't send it upstream? what does it need to be "proper code"?

tlwoerner: regarding your patch, I'm also not sure that non-ASCII characters should be part of patches
<dsimic>
also, having "[1]" with no actual numbered references doesn't make much sense :)
<tlwoerner>
haha, oops. thanks
<dsimic>
regarding non-ASCII, it should be "oC", "degrees C" or something like that instead of "°C", and "chapter" instead of the "§" character -- unless those are actually ASCII characters that I'm unaware of :)
<dsimic>
there's been a lengthy deiscussion about "oC" already
<jakllsch>
neither ° or § is ACSII
<dsimic>
thanks, then I'm afraid we shouldn't use them
<jakllsch>
° is ISO-8859-1
<jakllsch>
as is §
<maz>
"7 bits should be enough for everybody."
<dsimic>
just as 384 KB or whatever :)
<jakllsch>
640Ki
<dsimic>
actually, "Ki" is the same as "K", because "K" is non-standard already :)
<jakllsch>
eh, K is kinda ambiguious
<jakllsch>
i'd sooner be precise
<dsimic>
tlwoerner: regarding what's preventing Kwiboo's borrowed-from-downstream code from being acceptable upstream, that's hard to tell without going into minute details, which usually takes a lot of time
<dsimic>
jakllsch: I agree, using just "K" is a bit unclear, but it's technically equal to "Ki"
<jakllsch>
unless it means Kelvin :-P
<dsimic>
surely not when used as a unit prefix :)
<dsimic>
that's why I always use "KB", for example

dsimic: hehe, some assignments for my dayjob involve very little or no coding, so hobby linux/u-boot coding help fill such void ;-)
<Kwiboo>
tlwoerner: yep, the code for rk3308 thermal should be in decent shape and seemed to work okay, for upstream it will need i.e. dt-bindings, code and dt should be validated against trm and part of the code was possible c/p so could need proper attribution -> lots of work I have no desire to take on :-)
<dsimic>
Kwiboo: I see, but you must be having a lot of "unassigned time" at your dayjob :)

Kwiboo: I'm happy to hear it's working out for you :)
<dsimic>
tlwoerner: Kwiboo: just to reiterate, I remember firmly committed to doing the RK3308 thermal stuff, which includes a lot of "paperwork" that Kwiboo summed up well, and I hope Radxa wil eventually send me the boards I need, both for that and for my SoC binning endeavor
<dsimic>

<Kwiboo>
dsimic: great!, I hope they will send you some boards soon :)
<dsimic>
hopefully :)
<dsimic>
I've got more than enough boards with some SoCs, but I have e.g. zero RK3568-based boards
<dsimic>
while I obviously need to have at least a few boards with the same SoC for the binning project
<dsimic>
to be able to e.g. test on a couple of boards and have the third one running some long-term-ish stability tests
<dsimic>
oops... s/I remember/I stay/
<dsimic>
what a typo :)
<dsimic>
actually, s/I remember/I remain/
