<Ashleee> well I have more news. Apparently the board sometimes mis-detects memory as 2GB in which case I get the segfault because of paging fault
<Ashleee> when it comes detected as 4GB it is fine and gets to other CPU bringup
<Ashleee> so uh :)
<Ashleee> I need proper dtb for memory stuff :(
<Ashleee> can I build u-boot with rk3399 memory init blob?

<Ashleee> either way when it gets 4gigs correctly it suddenly stops at
<Ashleee> [ 0.000000] GICv3: CPU0: using allocated LPI pending table @0x0000000040170000
<Ashleee> [ 0.000000] GICv3: GIC: PPI partition interrupt-partition-1[1] { /cpus/cpu@100[4] /cpus/cpu@101[5] }
<Ashleee> [ 0.000000] GICv3: GIC: PPI partition interrupt-partition-0[0] { /cpus/cpu@0[0] /cpus/cpu@1[1] /cpus/cpu@2[2] /cpus/cpu@3[3] }
<Ashleee> and I have zero idea why :P
<sphalerite> Ashleee: does arm-smmu.disable_bypass=0 on the cmdline help by any chance?
<Ashleee> let me try
<Ashleee> nope doesn't help
<Ashleee> also for whatever reason initcall_debug goes ignored
<Ashleee> oh TRACEPOINTS_ENABLED
<Ashleee> hmm CONFIG_TRACEPOINTS is enabled though
<Ashleee> after the GICv3-- messages get_random_bytes() should be called and then arch_timer set up...
<Ashleee> at least based on other rk3399 logs
<Ashleee> this kernel 100% boots on a different rk3399 device

hexdump0815 has joined #linux-rockchip
<hexdump0815> Ashleee: i think on rockchip this is mostly due to low quality memory not working stable with the usual memory timings ... you might try to find one of the latest balbes150 images which has some rk3399 support for even tv boxes
<hexdump0815> Ashleee: or you can try to extract the dtb from android and take the memory timing from it and maybe use it in your dtb if it supports proper memory timing (rk3399 mainline does it i think - not sure which u-boot/atf is required for it to work)
<hexdump0815> Ashleee: what often worked for other rockchip devices to make them stable was to use the rockchip binary blob for the memory timing and mainline for the rest - there are csc ports of armbian for rk3288 and rk3229 doing this (maintained by jock)
<hexdump0815> Ashleee: this is how he is doing it for rk3288 - https://github.com/paolosabatino/armbian-build/blob/xt-q8l-v10/config/sources/families/rockchip.conf#L54-L62 - not sure if it works for rk3399 too - at least it helpd in getting mainline working stable on rk3328 and rk3318 boxes which were always unstable with u-boot's own memory timing
