Alex	In reply to @skeuchel:matrix.org Here are my estimates On the pioneer: Unregisterised release+profiled_libs: >30h Unregisterised quick+no_profiled_libs: 18h Registerised release+profiled_libs: 12h Registerised quick+no_profiled_libs: 9h Using qemu user-mode Registerised release+profiled_libs: 8h Registerised quick+no_profiled_libs: 6h I've measured ~22h for building an unregisterised GHC 9.2.8 booted via an unregisterised GHC 8.10.7 when running on VF2 (JH7110 SoC). (Default flavour with profiled libraries, dynamic libraries, and documentation enabled.) One minor difference to a typical RV64GC build is that I also enable Zba and Zbb. I have no idea what performance impact this has on my hardware. That a Milk-V Pioneer would take over 30h to do the same is surprising.	10:55:37

nix why-depends

See man nix3-why-depends

ok

The nom tree looks pretty clear btw: you have a git package in your path -- is that gitFull instead of the regular git?

i'll check

In reply to @skeuchel:matrix.org
Here are my estimates

On the pioneer:
Unregisterised release+profiled_libs: >30h
Unregisterised quick+no_profiled_libs: 18h
Registerised release+profiled_libs: 12h
Registerised quick+no_profiled_libs: 9h

Using qemu user-mode
Registerised release+profiled_libs: 8h
Registerised quick+no_profiled_libs: 6h

I've measured ~22h for building an unregisterised GHC 9.2.8 booted via an unregisterised GHC 8.10.7 when running on VF2 (JH7110 SoC).
(Default flavour with profiled libraries, dynamic libraries, and documentation enabled.)

One minor difference to a typical RV64GC build is that I also enable Zba and Zbb.
I have no idea what performance impact this has on my hardware.

That a Milk-V Pioneer would take over 30h to do the same is surprising.

I just remembered that I have logs, so:

configurePhase completed in 1 minutes 37 seconds
buildPhase completed in 21 hours 32 minutes 2 seconds
installPhase completed in 8 minutes 33 seconds
fixupPhase completed in 4 minutes 7 seconds

(unpack and patch phases don't appear to log timings.)

11:00:55

[0x4A6F]

Are you running on SDcard or NVMe on the VF2?

NVMe

I'm getting the following error when trying to build certain Haskell packages with a registerised GHC.

Couldn't find a target code interpreter. Try with -fexternal-interpreter

I thought registerised GHC included TemplateHaskell support?
Steven Keuchel do I need the patches that enable GHCi for this to work?

* is it possible to boot from a bcachefs partition comprise of nvme, emmc and (usb-connected) ssd?

07:23:47

@cnx:loang.net

ah nvm u-boot doesn't seem to support bcachefs

07:52:07

Pratham Patel (you can mention me)

you can keep /boot as ext4 and /boot/efi as efi and other partitions as bcachefs

07:53:10

Pratham Patel (you can mention me)

cnx: ^^^

07:53:26

@cnx:loang.net

i'm not familiar with u-boot (process), does it not load the kernel but efi?

08:24:47

Pratham Patel (you can mention me)

You can do both

08:25:37

Alex

In reply to @cnx:loang.net

The boot partition contains the systemd-boot loader, the kernel, and the initrd.

08:25:48

Alex

Or was it GRUB?

08:26:05

Pratham Patel (you can mention me)

but if you want a non-ext for rootfs, it's best to boot into a bootloader (grub/systemd-boto) from uboot and then load kernel

thanks!

Anyway, here's the full boot chain typically used on the JH7110-based SBCs:

ZSBL (ROM) -> OpenSBI and u-boot (usually flash) -> GRUB/systemd-boot (boot partition) -> kernel (boot partition) -> initrd, AKA NixOS stage 1 (boot partition) -> root system, AKA NixOS stage 2

08:29:19

@cnx:loang.net

how is opensbi and u-boot loaded?

08:30:04

@cnx:loang.net

i mean where are they loaded from a storage in case of sdio?

08:30:25

@cnx:loang.net

the beginning of the drive?
