marex: so on RISC-V we do the first one
00:06
<

but there's no standardization (like, X address is reserved for the variable)
00:06
<

so presumably EFI payloads need to somehow say "U-Boot, please start the secondary harts at address X"

Forty-Bot: isn't there OpenSBI on RV ?

sometimes
02:56

Forty-Bot: that's like hypervisor firmware which is in control of bringup cores up and down

it does the magic and hands over fully configured core to OS

ok, so I guess opensbi is mandatory for efi then

well, you can get efi on a riscv board via opensbi -> u-boot -> efi ...
03:30
<
vagrantc >
as u-boot has an efi implementation ... but ...
03:37
<
Forty-Bot >
this whole thing came out of discussion about whether exit boot services should do a smp_call_function
03:38
<
Forty-Bot >
and afaik exit boot services is when U-Boot turns over almost all of its memory to the payload
03:38
<
Forty-Bot >
which I believe includes secondary_hart_loop
03:38
<
Forty-Bot >
so if you are on a multi-core system and there's no opensbi...

i briefly used some riscv systems before opensbi was ready ... but have almost exclusively used opensbi+u-boot since

hi there .. did anyone try to boot the current master on an imx8mq NXP EVK board?
12:09
<

for me it looks like the SPL is started and when trying to start/initialize the U-boot the board hangs and will be reset.
