Status Information Fiasco.OC-UX

Fiasco.OC-UX is fully included in the standard Fiasco.OC tree and can be configured via the kernel build system.

Functionality

Supported Linux Kernels	2.6 - 4.x
Supported Processor Architectures	x86 only (Intel, AMD, other x86 compatibles)

Performance

Because Fiasco-UX emulates a µ-kernel in user-mode, there is a performance penalty of a factor of about 50 to 100 for context switches compared to the native Fiasco kernel. This is comparable to the performance loss of User-Mode-Linux compared to native Linux.

Fiasco-UX doesn't have the real-time properties of the native Fiasco kernel.
