Hello Hal,
I start to play with jh7110-starfive-visionfive-2-v1.3b I have collect
your series [3]. Now I'm trying to boot the image with the following
cmds:
setenv bootfile vmlinuz;
setenv fileaddr a0000000;
setenv fdtcontroladdr 0xffffffffffffffff;
setenv ipaddr 10.0.0.100;
setenv serverip 10.0.0.1;
setenv kernel_comp_addr_r 0xb0000000;
setenv kernel_comp_size 0x10000000;
tftpboot ${fdt_addr_r} jh7110-starfive-visionfive-2-v1.3b.dtb;
tftpboot ${kernel_addr_r} Image.gz;
run chipa_set_linux;
booti ${kernel_addr_r} - ${fdt_addr_r}
This the result:
Bytes transferred = 109443584 (685fa00 hex)
StarFive # run chipa_set_linux;
StarFive # printenv file
fileaddr filesize
StarFive # printenv filesize
filesize=685fa00
StarFive # booti ${kernel_addr_r} - ${fdt_addr_r}
Uncompressing Kernel Image
## Flattened Device Tree blob at 46000000
Booting using the fdt blob at 0x46000000
Using Device Tree in place at 0000000046000000, end 0000000046005c14
Starting kernel ...
clk u5_dw_i2c_clk_core already disabled
clk u5_dw_i2c_clk_apb already disabled
---------------------------------------------
I'm missing something? Any hints?
Many thanks in advance! :)
Regards,
Tommaso

Any hints? > Many thanks in advance! :) You can try the instructions at the link [1]. The branch [1] is based on v2 of this series, so you need to change the dtb name to "jh7110-starfive-visionfive-2-v1.3b.dtb" when using tftpboot. I will send v5 and update it to [1] this week.

This is a fix for my stupidity in the commit you mention: https://lore.kernel.org/linux-riscv/20230302174154.970746-1-conor@kernel.org/ But the main backtrace there is not from that patch at all, I think it is Linus' fault. The HEAD of Linus' tree is currently 8ca09d5fa3549 ("cpumask: fix incorrect cpumask scanning result checks") should be a fix for the backtrace that you are seeing above. > Any options I am missing?

Cheers, Conor.

The VisionFive board can boot up successfully if and only if all above two applied. The VisionFive 2 board can boot up successfully if I merge Linus's new changes.

If you only have a VisionFive 2, it shouldn't matter to you, as you don't need to fix up any SiFive errata (at the moment at least). Linus' fix is already in his tree, so should be in -rc2! The fix for the VisionFive was applied to Palmer's RISC-V fixes tree last night: https://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux.git/commit/?h=fixes&id=bf89b7ee52af5a5944fa3539e86089f72475055b Thanks, Conor.

Unfortunately, this g<sha> bit doesn't mean anything outside of your repo so it's hard to infer anything from that. This looks exactly like a bug is in v6.3-rc1, but Linus fixed in like the second commit *after* -rc1. What branch/commit/tag did you apply the series on top of? Cheers, Conor.
