kernel

The Linux kernel is written in C, but it also leverages extensions provided by GCC. In 2022, it moved from GCC/Clang -std=gnu89 to -std=gnu11. This article explores my notes on how these GNU extensions are utilized within the kernel.

I was asked about a segfault related to lld linked musl libc.so on PowerPC64.

• /usr/lib/ld-musl-powerpc64le.so.1 /path/to/thing worked. The kernel ELF loader loads rtld and rtld loads the executable.
• /path/to/thing segfaulted. The kernel ELF loader loads both rtld and the executable.

Therefore the bug is likely due to a difference between the two modes.

我需要一台散热小一点的笔记本，i5 ivy bridge，4G RAM，13.3/14 英寸，madper 推荐了款 HP 的 ultrabook，那东西卖得很畅销，早已没了，我就选了这个 SVT13117ECS。回家后第二次用附带的 Windows，也是最后一次使用，把硬盘驱动等信息截图用 nc 传给了我的 Gentoo 台式机。还是要吐槽一下 OEM Windows 7，500G 的硬盘只设置了三个分区，两个是还原什么的作用，隐藏的，留下一个400多GB的C盘。假使我使用 Windows 也免不了要重装呢。
