Docs: Possibly missing a value or two?

[IngwiePhoenix]

Hello there!

I have spent some time trying to compile the upstream kernel for my VisionFive2 with the options that I would like it to have. However, it won't boot.

After much trial and error, I can rule out SBI, uBoot, it's uEnv.txt file and even extlinux (although I had to adjust /etc/default/u-boot and manually add fdtdir /dtbs).

I followed the description in the README, making sure that the VisionFive specific parameters are in fact set:

root@riscboi /o/linux (JH7110_VisionFive2_upstream) # echo; for k in SOC_STARFIVE CLK_STARFIVE_JH7110_SYS PINCTRL_STARFIVE_JH7110_SYS SERIAL_8250_DW; echo "--> $k"; cat .config | grep $k; end

--> SOC_STARFIVE
CONFIG_SOC_STARFIVE=y
CONFIG_SND_SOC_STARFIVE=y
--> CLK_STARFIVE_JH7110_SYS
CONFIG_CLK_STARFIVE_JH7110_SYS=y
--> PINCTRL_STARFIVE_JH7110_SYS
CONFIG_PINCTRL_STARFIVE_JH7110_SYS=y
--> SERIAL_8250_DW
CONFIG_SERIAL_8250_DWLIB=y
CONFIG_SERIAL_8250_DW=y

I also checked for JH7110 and STARFIVE in general:

Aside from the audio module being built as a shared module, nothing stuck out to me here.

Is there something I am missing? I did use the existing defconfig and just added my own settings through menuconfig.

Here is the full config (kernel-config.txt) and resulting debian packages:
upstream-build.tar.gz

In addition, here is my current uEnv.txt:

#fdt_high=0xffffffffffffffff
#initrd_high=0xffffffffffffffff
#kernel_addr_r=0x44000000
#kernel_comp_addr_r=0x90000000
#kernel_comp_size=0x10000000
#fdt_addr_r=0x48000000
#ramdisk_addr_r=0x48100000

# Move distro to first boot to speed up booting
boot_targets=distro mmc0 dhcp
# Fix wrong fdtfile name
fdtfile=starfive/jh7110-visionfive-v2.dtb
# Fix missing bootcmd
bootcmd=run load_distro_uenv
run bootcmd_distro

(I commented out the script parts, because I was taking this from the network booting example. This is also the config currently being booted whilst I grabbed files off it; but it's currently in the 5.15 kernel.)

Thank you very much, good luck with the patch merging into upstream and kind regards,
Ingwie
