00:52 <takiama> anyone here running asahi-alarm? need a partner to debug issues with steam

07:58 <stintel> ugh, having trouble finding a boot command to recover from my broken grub

08:01 <stintel> here's what I'm doing: load nvme 0:6 ${kernel_addr_r} boot/vmlinuz-6.12.10-asahi-2-arm64; load nvme 0:4 ${fdt_addr_r} t8112-j415.dtb; load nvme 0:6 ${ramdisk_addr_r} boot/initramfs-6.12.10-asahi-2-arm64.img; setenv bootargs "console=tty0 root=/dev/nvme0n1p6"; booti ${kernel_addr_r} ${ramdisk_addr_r}:${filesize} ${fdt_addr_r}

08:01 <stintel> kernel loads but then nothing

08:02 <stintel> those _addr_r variables exist in env, all 3 files load fine

08:04 <jannau> do not load the dtb from disk, only the prepared one from m1n1 is usable

08:04 <jannau> `booti ${kernel_addr_r} ${ramdisk_addr_r}:${filesize} ${fdtcontroladdr}` should work

08:05 <jannau> after just loading kernel and ramdisk

08:05 <stintel> ah, fdtcontroladdr is new to me, let me try that

08:06 <stintel> neat, that worked, thanks!

08:06 <stintel> didn't even need bootargs

08:09 <stintel> ok so now I ran grub-install --efi-dir /boot/efi --disable-shim-lock --no-nvram

08:10 <stintel> it appears does not update EFI/boot/bootaa64.efi - only EFI/gentoo/grubaa64.efi

08:10 <stintel> and since we cannot write EFI variables, I would expect u-boot to load EFI/boot/bootaa64.efi

08:12 <stintel> ok I manually copied EFI/gentoo/grubaa64.efi to EFI/boot/bootaa64.efi and now grub is working again

08:12 <stintel> and the 6.14.2 dist kernel is now also working \o/

08:13 <stintel> I wonder if I even need --disable-shim-lock, I suspect the problem came from grub-install not updating EFI/boot/bootaa64.efi

08:14 <stintel> yeah, works

08:19 <jannau> stintel: grub-install updates bootaa64.efi with --removeable

08:20 <stintel> gotcha

08:20 <stintel> jannau: thanks for the help, fdtcontroladdr and --removable is what I was missing
