 |
|
Habe einen CORE2DUO (mobile) auf einer x86 arch und würde gerne wissen was die nachfolgenden Kerneleinstellungen für Auswirkungen haben und ob ich diese für c2d merom auch tatsächlich brauche?!
| Code: | | /dev/cpu/*/msr - Model-specific register support (CONFIG_X86_MSR) |
| Code: | | 64 bit Memory and IO resources (EXPERIMENTAL) (CONFIG_RESOURCES_64BIT) |
| Code: | | MTRR (Memory Type Range Register) support (CONFIG_MTRR) |

| Quote: | | Write-combining allows bus write transfers to be combined into a larger transfer before bursting them over the bus to allow more efficient writes to system resources like graphics card memory. This often increases the speed of image write operations by 2.5 times, at the cost of losing the simple sequential read/write semantics of normal memory. |
