<drewfustini> Anyone familiar with using raw perf events on risc-v?
<drewfustini> I added this to DT:
<drewfustini> riscv,raw-event-to-mhpmcounters = <0x0040 0x0001 0xffffffff 0xffffffff 0x00000f8>;
<drewfustini> and i thought the arg would be 'r400001' in perf
<drewfustini> but it returns "<not counted>"
<jrtc27> those exist as an opensbi binding
<drewfustini> I think I add the raw event to opensbi with that device tree line... but I'm not sure how to query perf about it
<drewfustini> I can't find any examples of command line for raw events with perf on risc-v
<rneese> ok anyone here have a vf2 ?
<rneese> willing to test images

<conchuod> davidlt: updating my SPL to what they're upstreaming seems like it might've alleviated my DDR issues.
<davidlt> conchuod, there are DDR issues?
<conchuod> Well, I *assume* they're DDR issues. The failure mode is exactly like how MPFS was before we sorted out DDR training.
drewj has joined #riscv
<conchuod> e.g. falling over while trying to do a tftp in u-boot or the tftp working, and bootm loados failing
<conchuod> I need to use it a bit more before I am convinced that things are improved, but on the surface it appears that the u-boot/master from a week ago + their patchset is more stable.
<davidlt> Running DDR with wrong training data is definitely fun :) I remember that on Unmatched.
<davidlt> conchuod, so the board official firmware is causing you issues, but the stuff they are upstreaming seems to be OK?
<davidlt> I haven't seen similar reports, but I am not actively scanning them too.
<conchuod> davidlt: yup
<conchuod> I'm not confident in actually reporting it yet, but I'll give it another spin tonight & leave a T-b on the patches
<conchuod> davidlt: it was fine the first days I tried it, but after a few days of sporadic use it started boot looping 90+% of the time
<conchuod> rneese: depends on what you need tested

<rneese> just booting the img up and getting some dmg and log output
<conchuod> rneese: I probably can later today
<rneese> ok
crossdev has joined #riscv
<conchuod> Post whatever download link you need me to use as soon as you get a chance, so that when I can it's ready
<rneese> Armbian_23.02.0-trunk_Visionfive2_sid_current_5.15.0.img.xz
<rneese> first 1 is cli 2nd is xfce
<rneese> these are first stage testing imgs
<rneese> same work as the vf1 but with the vf2 kernel
<rneese> after you boot and login
<rneese> dmesg --color=always | curl --data-binary @- https://paste.next.armbian.com/log
<rneese> and then post the usrl
<conchuod> rneese: Is there a u-boot in that blob?
<rneese> it uses extlinux
<rneese> the uboot shold be in thespi
<rneese> did you update to the latest firmware yet ?
<rneese> or you on the base firmware
<rneese> you can flash them with xmodem adn a serial console
EchelonX has quit [Quit: Leaving]
<rneese> page 19-23 also explains the diff ways to flash the files
<conchuod> rneese: What does "latest" firmware mean?
brazuca has quit [Quit: Client closed]
<conchuod> I am running mainline u-boot spl + their patches
<rneese> this is the board main firmware
<rneese> and the have put out updates opensbi+uboot
<conchuod> I've got enough trouble with what they shipped for the SPL that I'm gonna keep running mainline + patches ;)
<rneese> this fixes alot of the issues that it had
<rneese> as thy fix thins new spi+uboot flashes witll come out
<dlan> for VisionFive2, any chance to run mainline kernel? or stuck at 5.15?
<dlan> I haven't got vf2 board, just asking..
<rneese> 5.15 at the min the mainline 6.1 is not ready
<rneese> we are hoping Esmil gets things moving soon
<rneese> there has not been work for about 3 months
<rneese> dont know why but this is where it left off
<rneese> we are hoping to rebase the 5.15.0 to 5.15.92 in the next week
<conchuod> Poor Esmil!
<rneese> they say 6.4 or 6.5 they hope to have the v2 mainlined but with out much work thus far

<conchuod> I think that's unfair, there's been a lot of work done by starfive so far.

<conchuod> Does your image expect that the u-boot uses the stock boot commands? I wiped my env so I guess I'll have to boot it manually?
<rneese> what did you change in the uEnv ?
<rneese> it had fixes in it
<rneese> to allow booting other images
<conchuod> Dunno to be honest, I think I ran eraseenv
<rneese> 1 min
<rneese> boot with out a sd card and printenv
<rneese> so I know what you need compaired to a default vf2 env
<rneese> I know I will need your serial and the macs for both interfaces if it hases it
<conchuod> Oh I kept those IIRC
<rneese> or you will have to flash the firmwat and uboot to rest
<conchuod> I just got rid of everything containing a boot command
<conchuod> I'll just boot it manually, it's not hard.
<rneese> ok
<rneese> ours boots on a single partition mmc1:1
<rneese> this is using old framework but its a test to get things booting our new frame work is about finished .
<rneese> major changes in the new builder framework
<rneese> ok heading out ft 9 to DR appt
<rneese> I will ping when I get back

<rneese> ok
<conchuod> Yah, sorry :/
<rneese> np
<conchuod> I need to pick up some more anyway so I'll try it then
