The slowest mainlining project out there.

Can't get my crappy kernel to work? Found a bug?

If only I had a board that could take multiple 060s.... 🤪

When just one more try before going to bed pays off.

Today's issue of can you spot the endian issue. Also, poor tux.

[linux-chenxing @linux_chenxing]

@kanpapa ナイス。DRAMの設定とかチューニングして性能がかなり上がりました。あとでまたバイナリをアップします。

[linux-chenxing @linux_chenxing]

@kanpapa カーネルを更新しました〜

[linux-chenxing @linux_chenxing]

@kanpapa カーネルとrootfsのバイナリを置きました。あとでhttps://t.co/WsuL6CPMKYにSDカードのつなぎ方とかも書きます。

[linux-chenxing @linux_chenxing]

@kanpapa おまたせしました。英語だけどフラッシュにu-bootを焼く手順書を書きました[0]. で、手順書に書いてあるふうに使えるバイナリも置きました[1].

me: "artists impression of mainlining an arm soc as a 1980s anime"
bing image creator thing: <see attached image>
me: spot on.

[linux-chenxing @linux_chenxing]

@kanpapa mmc_spiです。寝ちゃうぐらい遅いです。笑　あとでgithub[0]にバイナリと手順書をアップします。ちょっとまってね。

@cnlohr @patrick_riscv Just need to get clock and power on there too and you're set.

[linux-chenxing @linux_chenxing]

@cnlohr I want this too, but for m68k.. The kernel apparently supports loading FDPIC ELFs for almost everything but actually making a toolchain that can generate them is *something else*.

[linux-chenxing @linux_chenxing]

Weekend project scope creep.. there is no easy on-chip debugging for m68k so spent some time creating a machine in QEMU.

[linux-chenxing @linux_chenxing]

Can we (should we..) do mainline linux on a robo vacuum? https://t.co/Ls4wos3Opu

[linux-chenxing @linux_chenxing]

@trevorrudolph You'd need to write a timer driver, a serial driver and for Linux to work a IRQ driver.. but once I'm finished that should be pretty easy.

[linux-chenxing @linux_chenxing]

When a little messing around weekend project gets out of hand and you end up with a complete upto date port of u-boot for a 40+ year old arch.

[linux-chenxing @linux_chenxing]

Can you spot the alignment/GCC codegen bug?

[linux-chenxing @linux_chenxing]

Hard to see but.. 45 year old cpu (mc68000) does linux 6.7 with devicetree and all that jazz. #m68k #imfunatparties
