<davidlt[m]> Should we increase CONFIG_HZ?
<davidlt[m]> Right now we are 100, and all arches except x86_64 are on 100 too.
<davidlt[m]> x86_64 is at 1000
<davidlt[m]> Nah, let's stay at 100 or maybe later move to 250 :/
<rwmjones> slow hardware, so lower numbers should be slightly more efficient?
<davidlt[m]> yeah, and it's better for compile, etc.
<davidlt[m]> Most folks don't use it for desktop where responsiveness should be very important
* davidlt[m] working on the last updates (hopefully)
<davidlt[m]> Uboot should be released next week
<davidlt[m]> OpenSBI v1.1 is being built, followed by UBoot RC5 (I will enable "sbi" command too)
<davidlt[m]> New kernel is ready with tweaked defconfig, but still missing some changes to DT
<davidlt[m]> It' sooo hot
* davidlt[m] removes Unmatched tiny fan to get more airflow
<davidlt[m]> M/B Temp: +34.4°C (low = +0.0°C, high = +85.0°C)
<davidlt[m]> (crit = +85.0°C, hyst = +75.0°C)
<davidlt[m]> CPU Temp: +41.8°C (low = +0.0°C, high = +85.0°C)
<davidlt[m]> (crit = +85.0°C, hyst = +75.0°C)

<rwmjones> yeah I was thinking about doing that, but replacing it with a tall passive heatsink
<davidlt[m]> There is BOM so you could find exact SKU for the heatsink
<davidlt[m]> Technically it's clip on, thus easy to replace, but I never tried.
<davidlt[m]> HEATSINK FU740-C000 27X27MMX19.5MM WITHOUT FAN
<davidlt[m]> Radian INM27001-20.1W/2.1BU
<davidlt[m]> ATS ATS-61270R-C0-R0
<davidlt[m]> I don't really see anything exceptional on DigiKey for 27x27MM clip on
<davidlt[m]> Unless you plan to use thermal glue or something
<davidlt[m]> Looking at the video here
<davidlt[m]> So you can go from 19.5mm to 24mm
<davidlt[m]> In the video they don't use any thermal paste, that could help
<davidlt[m]> Yeah, so nothing significantly better
<davidlt[m]> ha, there is SBI based reset in u-boot!
<davidlt[m]> I need to enable that too!

<Esmil> Yeah, some day I'd like to know why it's better to implement that in OpenSBI rather the Linux.
<davidlt[m]> You mean SBI reset interface?
<Esmil> yes
<rwmjones> davidlt[m]: what's the video link?
<davidlt[m]> Maybe to avoid code duplication?
<davidlt[m]> I mean the same reset code will be used for U-Boot, UEFI, etc.
<rwmjones> I was going to get one of those self-adhesive heatsinks, like they use to RPis
<davidlt[m]> On that DigiKey link, next to Datasheets there is a video from the company explaining their lineup for the heatsinks
<rwmjones> be good to know the size of the SoC if you can measure it
<Esmil> right, but that goes for just about any driver, and then you end up with a meta-OS is M-mode
bkeys has quit [Ping timeout: 256 seconds]
<Esmil> i mean if we really need an OS with all the drivers in m-mode then I'd much rather that OS was Linux
<davidlt[m]> Well, reset is on x86_64 and aarch64 is not handled by Linux too
<rwmjones> come on digikey ... don't make me fill out an export control form for a heat sink
<davidlt[m]> What?

<davidlt[m]> v5.18.8 will be decent, already has 181 patches
