Marc has been working on the Linux kernel since an unexpected encounter with 0.99pl13 in 1993. His first contribution was merged in 1996 in the form of the original version of the MD driver.

Having played with fault tolerant systems at Bull, worked on exotic (and ultimately doomed) CPU architectures at Texas Instruments, and had fun with consumer electronics at TomTom, he has been with ARM since 2010, where he focusses on the Linux kernel, co-maintaining KVM/arm and some parts of the IRQ subsystem. He is also involved in some new aspects of the ARM architecture.

He has presented a number of talks at Linux Plumbers, ELC, and KVM Forum over the past years.
