Tag drtabb
Version: linux-2.6.32.3
- using new atom cpu type.
- concern about:
CONFIG_X86_CPU=y CONFIG_X86_L1_CACHE_BYTES=64 CONFIG_X86_INTERNODE_CACHE_BYTES=64
lshw reports 32 Kbyte L1 cache.
- CONFIG_PHYSICAL_ALIGN
previous kernel: CONFIG_PHYSICAL_ALIGN=0x200000 drtabb: CONFIG_PHYSICAL_ALIGN=0x1000000
- Switched to GSPCA for usb cam.
- Turned off AGP
- Had to hand edit the .confg for get usb printers off , FFS
- Had to hand edit # CONFIG_VIRTUALIZATION is not set
- powertop recommend I turn on CONFIG_CPU_FREQ_STAT but it is part of CPU scaling and I'm trying CPU idle , mutually exclusive.
- powertop recommend I turn on CONFIG_CPU_FREQ_GOV_ONDEMAND but it is part of CPU scaling and I'm trying CPU idle , mutually exclusive.
