  Dozens of minimal operating systems to learn x86 system programming. Tested on Ubuntu 17.10 host in QEMU 2.10 and real hardware. Userland cheat at: https://github.com/cirosantilli/linux-kernel-module-cheat#userland-assembly ARM baremetal setup at: https://github.com/cirosantilli/linux-kernel-module-cheat#baremetal-setup 学习x86系统编程的数十个最小操作系统。 已在QEMU 2.10中的Ubuntu 17.10主机和真实硬件上进行了测试。 Userland作弊网址：https：//github.com/cirosantilli/linux-kernel-module-cheat#userland-assembly ARM裸机安装程序位于：https：//github.c

Thankfully, I regained my sanity before going that far. The "a second CPU started" example at: https://github.com/cirosantilli/x86-bare-metal-examples/tree... though. I think some of the projects under https://github.com/cirosantilli/x86-bare-metal-examples/tree... did it though.

I get it, the PRC is probably one of the worst regimes on the planet, but writing a book about it on every README you publish in your toy projects is a classic sign of schizophrenia.

Yes, absolutely correct about possible QEMU simplifications. One option would be to use gem5 which can simulate caches/memory more accurately (sometimes), but it is also way slower as a result, some indications at: https://github.com/cirosantilli/linux-kernel-module-cheat/tr...
