- Kernel options
If you want to edit kernel options, note that the following are currently broken with Kerrighed:
* General setup -> IPC Namespaces * Processor type and features -> Preemption Model -> Voluntary Kernel Preemption * Processor type and features -> Preemption Model -> Preemptible Kernel * Networking -> IrDA (infrared) subsystem support * Security options -> Enable access key retention support * Networking -> Networking options -> The Ipv6 protocol
Note: don't forget to add NIC driver and, if you plan to use NFSROOT, include it in the kernel, not as module.
We meet…
- Kernel options
* Cluster support -> Active Fork Delay (Can't compiler, maybe this function doesn't release)
- Enable SMP (Kerrighed default .config don't enable it, you must choose CONFIG_SMP)
* Processor type and features -> Symmetric multi-processing support * Processor type and features -> ( ) Maximum number of CPUs (2-255)
- If CONFIG_HIGHMEM64G is set
kererighed: error: unknow symbol __support_pte_mask
- ipcs, can't see anything

We set Maximum number of CPUs = 32, then found the order of CPU index is seperated by 32
