<vagrantc> wow.
<vagrantc> i haven't seen u-boot boot on a firefly-rk3399 in quite some time ... still haven't gotten u-boot-spl and all that working, but did manage to boot with miniloader with 2018.03 for the first time in a while
<vagrantc> ../rkbin/tools/loaderimage --pack --uboot /usr/lib/u-boot/firefly-rk3399/u-boot.bin uboot-firefly
<vagrantc> -2018.03-2 0x200000
<vagrantc> the magic was passing 0x200000 ... which didn't used to be a required argument

<vagrantc> Ke: yes, just finally successfully tested the pre-built debian package
<vagrantc> Ke: of u-boot
<Ke> vagrantc: which debian version?
<vagrantc> Ke: doesn't matter much
<Ke> you mean all of them work?
<vagrantc> e.g. bootloader is a bit early for the OS to work
<vagrantc> to matter
* vagrantc is running debian-installer now
<Ke> I mean it is relevant, because not all of them might work
<vagrantc> i don't know which "them" you're referring to
<Ke> debian u-boots
<Ke> ie. which version of the "pre-built debian package" did you successfully use
<vagrantc> these include all the versions i was able to get to work https://wiki.debian.org/U-boot/Status
<Ke> thanks
* vagrantc would love it if other people would test it too
<Ke> are you using EFI boot with grub?
yann has quit [Ping timeout: 255 seconds]
<vagrantc> only very recently with firefly-rk3399
<Ke> ie. u-boot-grub-efi-linux
<vagrantc> this is the first test boot i've ever done using the EFI boot
<vagrantc> no
<vagrantc> just using u-boot's built-in EFI emulation/implementation and grub-efi
<vagrantc> i used u-boot 2018.03+dfsg1-2 from debian, with https://d-i.debian.org/daily-images/arm64/20180405-02:05/netboot/mini.iso plugged into USB
<Ke> communication is hard again today, anyway, you can probably report on your progress
<vagrantc> i typically file an installation report
<vagrantc> anyways, gotta head out.
<Ke> me too
<Ke> thanks

<vagrantc> hrm. debian-installer ran fine, but the initial boot failed ... maybe due to the issue with the fan53555 module

<Ke> has anyone tested any bootloader for samsung chromebook plus
<Ke> like coreboot or something
<Ke> recently
<Ke> now that I have testclips and ability to flash spi-nor externally, I might try
<Ke> especially I would like to get rid of the beep on bootin untrusted OS
wadim_ has quit [Ping timeout: 260 seconds]

<maz> Ke: this machine isn't affected by Meltdown. Only Spectre (and only on the A72).
<Ke> anyway, I still need the beep update and spectre update
<mmind00> Ke: when I got my Kevin sample device I did put on the netboot-only variant of the CrOS coreboot ... but that must have been more than a year ago already
<adj__> maz, Ke: it was written somewhere (maybe by arm inc.) that the unreleased cortex-a75 was affected by meltdown or similar
<adj__> it was unknown if it will be fixed before release
<adj__> Ke, mmind00: afaik, paulk was. He said that booting completely with free software is possible
Aussie_matt has joined #linux-rockchip
<adj__> I think that he uses the acer r13 because he prefers the form factor (13.3" instead of 12.1")
<Ke> adj__: yup, that's why I got mine
<Ke> https://developer.arm.com/support/security-update lists a72 vulnerable to variant-a3
<Ke> 3a
<maz> Ke: 3a is not Meltdown.
<Ke> samsung chromebook plus has the silly US keyboard, but it has a cover for the SD slot, which is really a big deal
<maz> Ke: also, you don't need any firmware support for either Meltdown or 3a.
<adj__> maz, yo mean to mitigate it, right?
<maz> adj__: yes.
vagrantc has quit [Quit: leaving]
<Ke> adj__: anyway firefly-rk3399 seems to be able to boot with free software, so I would very much assume Samsung Chromebook Plus woudl too
<Ke> free as defined by debian project
<adj__> if I remember correctly, for chromebook plus and r13 the only piece absolutely needed to boot of proprietary code was the power management processor of the r13
<adj__> I assume that in chromebook plus wifi is not replaceable...
<Ke> you mean outside of the soc
<Ke> replaceable for most people, you can always solder
<adj__> I mean, if it's a replaceable pci3 or usb module
<adj__> pcie
<Ke> it's somehow pcie but listed in devicetree
<Ke> as in the driver is pcie driver, but loaded on platform bus, I was moderately bamboozled on that spec
<Ke> but probably not replaceable
<NotKit> a bit offtopic, but is there any chance to use Mali T86x Rockchip Linux blobs for Mali T880 on MediaTek in case kernel part is ported to match?

<Ke> adj__: why not make us a proper laptop while you're at it, there is definitely at least a market of me
<Ke> not sure why the people making libre friendly laptops hate rk3399
Aussie_matt has quit [Remote host closed the connection]
<Ke> chromebooks have the slow and small mass storage problem
<Ke> also, I guess there could possibly be a bit more ram
<adj__> Ke, I own a novena laptop, and it used to be my main computer for some time
<adj__> the case and form factor was not ideal
<adj__> right now, we need to make compromises, one way or another
<adj__> biggest compromises for rk3328 and rk3399 are GPU and VPU

<mmind00> Ke: you would be surprised how much of your desktop relies on GL-portions nowadays [depending on your desktop environment of course]
<Ke> perhaps, I use C201 without gpu drivers now
<Ke> so not much of a surprise anymore
<Ke> with xmonad/lxde
<Ke> firefox is a bit slow on some effects and emulated hw rescale on video play is slow
<Ke> or chromium
<Ke> bigger issue is slower mass storage, which is actually unfixable without hw mods to my knowledge

<mrfixit2001> Anyone in here use genimage before? Want to confirm the correct offset values to assign to the boot.img and rootfs for the config file. I'm thinking I need to multiply the listed offsets in the rockchip wiki by 512. Just looking for confirmation :)

<dannysantos> Hi. mmind00 someone told me to talk to you about my archlinux on rock64 not getting usb3 sda1 to appear on the system. Can you help me with this?
<dannysantos> the power on my usb disk seems to work, but can't get an sda. usb2 works fine
<mmind00> dannysantos: usb3 isn't enabled yet on rk3328
<mmind00> dannysantos: while I had patches queued for basic support, the usb3 has some issues that needs special handling
<dannysantos> ok, so do you know when will it be enabled? I don't understand very much about this stuff
<dannysantos> mmind00, ok I understand
<mmind00> dannysantos: not sure yet ... need to find time to resolve ... although I do hope to find the time for things to be able to make it into 4.18 ... but don't quote me on that ;-)
<dannysantos> ok :)
<amstan> mmind00: dwc3?
<dannysantos> thank you for the info mmind00
<mmind00> amstan: dwc3, innosilicon usb3-phy ... and that phy doesn't handle unplugs well
<amstan> heh
<mmind00> amstan: so once you unplug a device it won't recognize new ones until it gets reset
<amstan> sounds like a driver similar to dwc3-rockchip.c would fix it, but that would require an extcon too
<mmind00> amstan: I picked and cleaned patches from the vendor tree, but need more time to look closely
<dannysantos> you guys are awesome. thank you for your work job :)
<mmind00> I'll get to it, especially as a friend of mine is using a rk3328-based tv-box as home-server and is hounding me as well for usb3 support :-D
<amstan> mmind00: heh, nice
<amstan> mmind00: yeah, i saw dannysantos asking about usb3 in #archlinux-arm, so i pointed him here
<dannysantos> mmind00, thank you. I also have rk3328 as a server
<dannysantos> I'll wait for 4.18 mmind00
<dannysantos> thanks a lot
<dannysantos> :)
<dannysantos> thank you mmind00 and amstan :)

<adj__> amstan, I think that Ke was talking about using a PCIe GPU card that works with free software
<amstan> adj__: darn, sorry
<amstan> adj__: but that sounds cool too!
<adj__> :), don't worry
<amstan> what gpu cards are we talking about?
<amstan> something like ati or nvidia?
<adj__> afaik, if you want free software even for the firmware, only some a bit old nvidia cards
<adj__> with nouvou driver
<adj__> but I'm not absolutely sure that would work with rk3399
