| ====== Kernel ====== | ====== Kernel ====== | ||
| - | We'll need to configure an SMP kernel to get full functionality of our systems. | + | To get full functionality from our systems, we had to install an SMP kernel. The default non-SMP kernel only saw 1 of our 4 CPUs and 1 GB of our 4 GB of RAM. |
| - | * We need to add SMP support so we can use all 4 CPUs. | + | We chose to stick with a 2.4 kernel, to be conservative, and stick with what Debian recommends. |
| - | * We need to add large memory (4 GB) support. | + | |
| - | * We need to remove ACPI support, and add APM support. | + | |
| - | * Remove USB and sound, as this system does not have them. | + | |
| - | * Remove SymBIOS SCSI drivers, as we've got nothing attached to that controller. (We're using the ida driver for the SmartArray 4200 RAID controller.) | + | |
| - | ====== Initial test on Bud - download SMP kernel ====== | + | ===== Installation ===== |
| - | Downloaded and installed: | + | Install the kernel headers and SMP kernel image. |
| - | kernel-headers-2.4.27-2 | + | # apt-get install kernel-image-2.4.27-2-686-smp kernel-headers-2.4.27-2-686-smp |
| - | kernel-image-2.4.27-2-686-smp | + | |
| - | Package installation updated GRUB, .. next step is to try and boot the SMP kernel. | + | The package installation also updated the GRUB configuration. |
| + | |||
| + | Reboot the server to load the new kernel: | ||
| + | |||
| + | # init 6 | ||
| + | |||
| + | ===== Testing ===== | ||
| + | |||
| + | On reboot, check to see that the system sees all 4 CPUs: | ||
| + | |||
| + | $ cat /proc/cpuinfo | ||
| + | |||
| + | Check to see that 4 GB of RAM is also enabled: | ||
| + | |||
| + | $ cat /proc/meminfo | ||
| + | |||
| + | (There are several other ways to verify this information, including the **top** and **free** commands.) | ||
| + | |||
| + | ===== TODO ===== | ||
| + | |||
| + | We'd like to compile a custom kernel to help with a few more issues: | ||
| + | |||
| + | * Remove ACPI support, and add APM support. (Both deal power management, but our systems only support the older APM standard.) | ||
| + | * Remove USB and sound, as our systems do not have those features. | ||
| + | * Remove SymBIOS SCSI drivers, as we've got nothing attached to those controllers. (We're using the **ida** driver for the SmartArray 4200 RAID controller.) | ||
| + | |||
| + | See the following pages for info on packaging the kernel the Debian way: | ||
