<vagrantc> beeble: which .dtb file does u-boot use on puma_rk3399 ... i see several ... u-boot defaults to 1600 ?
<beeble> vagrantc: yes, default is 1600. 1866 will work too but there is no real benefit in most usecases
<beeble> the defconfig should work fine? if you are missing something i'm ppen for suggestions
<vagrantc> beeble: just wondering what to put in the package
<vagrantc> beeble: since ATF isn't in debian yet, i'll reference building m0 and ATF with an external repository, and how to get a working image
<vagrantc> beeble: although the m0 part actually was pretty straightforward to package
<vagrantc> and the licensing is clear
<vagrantc> still, the whole ATF mess is a little ugly
<beeble> have to take a looknat mainline and rockchip upstream again
<beeble> haven't followed it that closely as the current stuff works fine with linux
<beeble> but at least for android there is now additional stuff that should be merged or we get our stuff closer to mainline again
<BenG83> moin
<vagrantc> beeble: yeah, it'd be nice to have at least one target in mainline ATF that worked on at least one board that i can test :)
<vagrantc> beeble: someone uploaded an allwinner fork of ATF to debian ... and i don't really want to have dozens of vendor forks in debian
<vagrantc> allegedly that is being merged upstream, at least
lurchi__ is now known as lurchi_
<beeble> fully understandable. atf upstreaming is just not yet an established workflow. by time we will figure it out
matthias_bgg has joined #linux-rockchip
<BenG83> if you have any questions about ATF upstream, ask André/aprtizel from ARM
<beeble> it's more about sime design decisions currently implemented. we want the m0 firmware split out. others not. have to find consent
<beeble> sorry for typo hell again. should buy one of this 6+ inch phones for bigger keys :)
<BenG83> :)
<BenG83> are both of the m0 cores used in off the shelf RK software stacks?
<beeble> current atf uses both now iirc
<beeble> since a few months
<BenG83> as far as I understand one manages the PMIC?
nots has joined #linux-rockchip
<beeble> should only be required for standby. the kernel has it's own pmic driver during normal operations
<beeble> at least last time i checked there was no pcsi stuff
<beeble> but could have changed now. for bsp 4.4 mainline uses pmic directly over i2c
<BenG83> totally different topic, has anyone got RK3399 to train all 4 PCIe lanes with an endpoint device?
<beeble> yes
<ayufan> not yet
<ayufan> my rockpro failed badly
<ayufan> only got pciex1
<beeble> tkaiser asked a few days ago. so i wanted to recheck. but atm i can only find single lane devices in my lab. except a sas card, that one trains well on x4 but i don't have anything to attach to the card
<BenG83> I have a 10GbE card sitting here ready for testing one my RockPro arrives
<beeble> i have some new cards in backorder that should arrive soon
<ayufan> I have PM981 for testing :)
<BenG83> the new RockPro's have the reworked 3.3V power path
<BenG83> should be much better for NVMEs
<beeble> the fpga card on my colleagues desk works fine too in x4 but there aren't really any througput benchmarks
<beeble> so let's see what the nvme is doing when i get it
matthias_bgg has quit [Ping timeout: 268 seconds]
<BenG83> yeah what I really would like to know is if there is enough interconnect bandwidth in the RK3399...
<beeble> there may be some qos changes required in that usecases
