chrisf_: I suggest you avoid raw register operation to the CPU configuration registers
<MoeIcenowy>
but use PSCI instead

MoeIcenowy: Thanks. I've found ARM's documentation for that now but can't see reference to that in the H5 RM. Is it a standard ARMv8 feature?
<parazyd>
i can see three requests on the server, looking like this:
<parazyd>
Jul 17 13:02:12 rishi daemon.notice rpc.mountd[22048]: authenticated mount request from 10.11.11.230:978 for /export/armhf_buildslave_lime2 (/export/armhf_buildslave_lime2)
<parazyd>
could it be a filesystem problem? that the server is on btrfs, and this kernel doesn't have it builtin?

parazyd: maybe you should try testing nfs mount from a ramdisk first to get more info
lemonzest has joined #linux-sunxi
<parazyd>
don't have any prepared ones on hand...
indy has quit [Ping timeout: 240 seconds]
<pmpp>
parazyd: i don't use nfsroot but aoe, but sometimes network is quite slow to go up so i use "rootwait" kernel cmdline param, that helps a lot
indy has joined #linux-sunxi
<pmpp>
parazyd: what is your kernel boot arguments line ?
<pmpp>
parazyd: aoe is great but single client for root image
<pmpp>
i'd try "rootwait rootfstype=nfs" that can't hurt
<parazyd>
yeah i don't think i need multiple boards using the same rootfs
<parazyd>
pmpp: you have some guide to AoE that might be useful for me?
* parazyd
trying those args
<pmpp>
i you have ssd on server and gigabit board you'll love AoE
<parazyd>
i do! :)
<pmpp>
just to "apt-get install vblade" on server then
<parazyd>
server is gentoo though :p
<pmpp>
emerge then :p
<parazyd>
yep
<pmpp>
on client you'll need to add aoe as builtin if you don't have ramdisk
codekipper has quit [Ping timeout: 258 seconds]
<parazyd>
yeah i think i'd prefer not messing with initrds for the time being
<parazyd>
yeah, let's go for AoE :D
<parazyd>
this isn't working out
<pmpp>
btw vblade support sparse image file so you can declare any size
<parazyd>
interesting
<KotCzarny>
parazyd, first, check if you have exported the share
<KotCzarny>
to the ip your client is getting
<parazyd>
as said, in the server i see it
<parazyd>
Jul 17 13:02:12 rishi daemon.notice rpc.mountd[22048]: authenticated mount request from 10.11.11.230:978 for /export/armhf_buildslave_lime2 (/export/armhf_buildslave_lime2)
<pmpp>
iirc there's a "no_root_squash" to add too
<parazyd>
i did add it
<parazyd>
but yeah if you have anythingin mind i can try it later
cnxsoft has quit [Read error: Connection reset by peer]
<parazyd>
now going to try AoE
<pmpp>
yeah aoe beats Nightmare FileSystem ;)
<parazyd>
lol
<KotCzarny>
pmpp: in one client one image, sure
<pmpp>
KotCzarny: overlayfs ;)
cnxsoft has joined #linux-sunxi
<parazyd>
overlayfs rocks
<KotCzarny>
parazyd, can you check if you have CONFIG_ROOT_NFS in the kernel?
<parazyd>
KotCzarny: i do
<pmpp>
KotCzarny: sometimes nfs just doesn't want to work between different kernel version on client and server
rocketpenguin has joined #linux-sunxi
<KotCzarny>
rootserver=10.11.11.135, rootpath=
<KotCzarny>
maybe you need to add rootpath in dhcp?
<parazyd>
such as?
<pmpp>
hmm i have 'option root-path "aoe:e0.0"' for ipxe sanboot
<pmpp>
KotCzarny: root-path is for tftpboot no ?
<KotCzarny>
dont know, guessing atm
<KotCzarny>
and another site suggests rootdelay=5 and similar waits
<pmpp>
i only have rootwait but aoe is fast cause no ip
<pmpp>
but he saw the mount attempt server side
<pmpp>
so maybe some gremlins
<KotCzarny>
best course of action is booting something else with that ip and checking if mount works and what exactly is there
<KotCzarny>
random google: The problem turned out to be the NFS protocol version. The target board apparently wants to use version 2 by default, but that isn't supported in CentOS 7. Adding ",nfsvers=3" to the nfsroot variable in bootargs solved the problem
<pmpp>
hmm more 3 vs 4, nfsv2 is prehistoric
<KotCzarny>
but guy was getting -6 too
<pmpp>
but you can upgrade v3 to 4 at boot
chlorine has quit [Remote host closed the connection]
<pmpp>
so if nfsv4 root support is on it should handle all cases
<pmpp>
probleme could be nfsv4 only server
<KotCzarny>
that might be it, ie forcing nfs v3

lurchi_ is now known as lurchi__
<parazyd>
dunno it's weird
<parazyd>
pmpp: so what can i use on the cmdline for aoe?
<pmpp>
if you export with "vblade 0 0 eth0" you put root=/dev/etherd/e0.0
alexxy has quit [Quit: No Ping reply in 180 seconds.]
<pmpp>
you can do partitionless
<parazyd>
it's a .img with one ext4 partition
<parazyd>
does it matter?
<pmpp>
root=/dev/etherd/e0.0p1 then
<parazyd>
i guess i would append p1 ?
<parazyd>
yes, thanks
alexxy has joined #linux-sunxi
<pmpp>
ho you need fs type module builtin too
<pmpp>
but as you have brtfs server ext4 is fine
<parazyd>
yeah i suppose it is
<pmpp>
not sure about if compression best on server or client side
<parazyd>
[ 3.694684] Waiting for root device /dev/etherd/e0.1p1...
<parazyd>
i did put rootwait
<pmpp>
yeah you must unless you have a ramdisk to do "echo > /dev/etherd/discover
<pmpp>
you exported with : vblade 0 1 eth0 ?
<parazyd>
yes
<parazyd>
brb
<pmpp>
ho yeah bbl too hungry there :p

Could someone point me at an example ATF call? I've got it loaded into SRAM_A2. Does u-boot make any ATF calls?

wens: my tcon1 branch rebased on v4.13-rc1 works fine running i2cdump -y 2 0x50 after booting
<wens>
:/
<wens>
probably because ddc on the a31 has a separate clock :/
<Net147>
wens: maybe the clocks are enabled in different order?
<Net147>
wens: are all the relevant clocks enabled in clk_summary?
