me_s: I recently ported latest U-Boot and Kernel to rk3399 rock64 enterprise edition. It was a little bit hard, but the only thing I had to do was have a correct Devicetree, with the right RAM and all the right stuff.
<ezequielg>
I will post patches to U-Boot ML tomorrow.
<me_s>
cool
<me_s>
thanks
<ezequielg>
me_s: One thing... I managed to flash the wrong bootloader to emmc. So I had to solder some stuff to shortcut the EMMC clock and have the board boot from a removable SD card, which is IMHO more hacker friendly.
<ezequielg>
gotta go! 9pm here!

ezequielg: rock960?
<lvrp16>
so many rocks it's getting confusing XD
<lvrp16>
is it the lpddr3 or lpddr4 version of the rock 960?

@fysa, likes your rock64 bionic LXDE desktop screenshot
<fysa>
now you see why I want 6GB RAM+ :)
<tl_lim>
that is 4K screenshot?
<tl_lim>
R64 and RPro64 both max at 4GB

I don't think that 4GB is a big limitation for rk3328, but for rk3399 it is

Wish that RK3399 can handles more than 4GB memory space.

4k is too slow for desktop with armsoc :)
<fysa>
4gb is probably just right for 3328 yes

would be even better with a keyboard, mouse and ethernet connected to the screen :P

About the new Samsung Chromebook Plus V2, BE CAREFUL: the new one has "Intel Inside". Say goodbye to rockchip, I hope that the old one is available for some time, but don't wait if you absolutely want a rk3399.
<adj_>
another changes are: 16:10 aspect ratio display (instead of 3:2) with lower resolution and lower brightness and an additional USB 3.1 type A port
<adj_>
and 50$ more expensive
<adj_>
ah, it seems that it is 16:9 display 1920x1080 but that can "software scale" to 1920x1080, so even worse
<adj_>
"sotware scale" to 1920x1200, I meant
<adj_>
"thanks companies for using the same marketing name for hardware with different architectures"
<TheKit>
what the cheapest "reasonable" device would you advice to try Rockchip? Rock64?
<adj_>
probably a cheap usb dongle
<adj_>
rock64 is the most inexpensive (25-45$) I have seen with good distribution support
<adj_>
rock64 is supported at least by armbian and archlinuxarm
yann has quit [Read error: Connection reset by peer]
<adj_>
so for my taste, the Plus V2 only has downsides: Intel with all the freedom/security problems, much worse display, lower case in plastic instead of aluminum, heavier, heavy display with bad overall weight balance, bad camera and 50$ more expensive
<adj_>
only improvement is better single thread performance
<Ke>
to be honest, some company could just do a decent rk3399 laptop
<Ke>
mostly: improve the mass storage option
<Ke>
not sure, if more ram is possible, probably not economically viable
<adj_>
I don't know if pcie ssd's have been tried with rk3399, that would be a great adition
<adj_>
do they sell it with a pcie ssd, or just the m.2 connector?
<adj_>
anyone has tried an ssd?
<Ke>
I would extrapolate so, but did not confirm
<Ke>
I had antipathy towards pcie mass storage, since it often has DMA also outside of the iommu
<Ke>
as I traditionally see mass storage as external devices and not as parts of the computer
<Ke>
like with sata
<Ke>
partly because it wears and needs to be replaced
<adj_>
what iommu does if the devices connected can access memory outside of the memory mapped to it?
<Ke>
obviously application processor should not trust any peripheral in perfect world
<Ke>
iommu is not properly initialized before pci devices are started in many scenarios
<Ke>
like with u-boot
<Ke>
this was the case with mcbin-armada-8040
<adj_>
do you have any link to a page explaining which ssd's with which iommu can access not assigned memory?
<Ke>
no, just a casual irc chat with the person tweaking the support
<Ke>
in security terms I would first look at the bootloaders and such
<Ke>
I assume linux is sane, once it's properly runnign, but really no idea
<Ke>
but even then obviously not all devices are handled by some iommus

I suppose that it could be worked around power gating pcie devices, but that's a hardware modification and would be difficult for devices directly connected with the power supply

@seanpaul: pong
<seanpaul>
tllim: had a question about the ROCKPro64, I saw it's using rk3399, are you (or have you tried) using drm_hwcomposer for the android image?
<seanpaul>
(saw Lukasz's post on chromiumos-dev)
<tllim>
no idea, based on RK engineer inout, I thinks so
<tllim>
if ayaka online, he can provide a correct answer
<seanpaul>
tllim: ah cool! do you know where i can find the source?
<tllim>
the Android 7.1 SDK already posted on PINE64 wiki site.
<seanpaul>
just curious, mostly. i strongly suspect someone could get the mainline drm_hwcomposer (HWC2) running on the rockpro without too much trouble
