asm/io.h
I/O port access
メモ
マクロ・関数
traditional input/output functions (I/OマップドI/O)
the "generic" interfaces for doing new-style memory-mapped or PIO accesses. (メモリマップドI/Oの新しい形式)
readX/writeX (メモリマップドI/Oの古い形式)
- readX/writeX() are used to access memory mapped devices. On some architectures the memory mapped IO stuff needs to be accessed differently.
- On the simple architectures, we just read/write the memory location directly.
その他
- ioremap
- ioremap_nocache
- ioremap_wc?
