08:51 <narmstrong> odalg: I think I saw it when testing the driver intially then I only tested headless

08:51 <narmstrong> odalg: it must be a ddr access priority issue, but all this is absolutely not documented

18:04 <odalg> chewitt: I am not able to complete fio with bsp kernel, one one of my nvme's is not recognized, the other is, but gives different timeout errors when writing. Both work just fine with 5.5 kernel. Doing hdparm -tT works with bsp kernel gives no flicker

18:07 <odalg> Two other "issues":

18:08 <odalg> 1 - with mainline u-boot and 5.5 kernel - the usb-c power supply always uses 5V - bsp kernel and u-boot select 9 or 12V depending on powersupply

18:12 <odalg> 2 - network performance is better with bsp kernel, more than 900mbit for tcp with iperf3, no mather which direction. Using one of the faster cores for the eth0 irq, ksoftirqd uses less than 1% cpu, no mather which direction

19:50 <odalg> mainline kernels use close to 100% cpu on ksoftirqd during iperf3 tcp tests

20:54 <narmstrong> odalg: there is definitely something wrong for network, but we failed to find what

20:55 <narmstrong> odalg: yep the usb-c is not handled in v5.5

20:56 <odalg> narmstrong: udp seems to have much lower ksoftirqd cpu usage

21:12 <odalg> narmstrong: Does the usb-c handling have another name on http://linux-meson.com/doku.php ?
