Linux, on the other hand, doesn't let you send data to SPI without a CS line, and the CS lines are fixed in hardware as well. For example on the Raspberry Pi, there's only two CS pins available for the hardware SPI pins - CE0 and CE1 - and you have to use them.

SPI devices have a limited userspace API, supporting basic half-duplex read() and write() access to SPI slave devices. Using ioctl() requests, full duplex transfers and device I/O configuration are also available. Accessing SPI Devices in Linux The Linux kernel provides a device driver for the SPI controller of the STM32F7. Appropriate kernel configuration options are enabled in the rootfs project that is installed to each STM32F7 System-On-Module shipped by Emcraft.
