How to increase vmalloc space size in the kernel 2.6.11.4?
i need to drastically increase vmalloc space in my machine. The system default value is 128MB.
Our system platform: OS: SuSE 9.3 Kernel: 2.6.11.4-20a-smp Cpu: double xeon 3.6GHZ Ram: 4GB HardDisk: SCSI 40GB Motherborad: microstar I use 'vmalloc=256m' to config my linux vmalloc space. after a reboot, the console outputs some information as below: kernel: allocation failed: out of vmalloc space - use vmalloc=<size> to increase size How to increase the vmalloc space?:confused: |
Well, first of all... even though your hardware supports 4GB, did you compile that kernel with big-memory support? When you boot up the system without that parameter, what does cat /proc/meminfo tell you?
I find it very helpful to grep the actual Linux kernel source-code to find the actual programming that generates any message, or that evaluates any kernel parameter. |
