Message-ID: <8355959a0701200214r7dd68d4br97a8cbe091dfaaab@mail.gmail.com> (raw)
Hello,
I did find this dmesg for the kernel 2.6.20-rc5
Linux version 2.6.20-rc5-Typhoon (root@Typhoon) (gcc version 4.1.1
20061011 (Red Hat 4.1.1-30)) #1 SMP Sat Jan 20 15:00:20 IST 2007
BIOS-provided physical RAM map:
sanitize start
sanitize end
copy_e820_map() start: 0000000000000000 size: 000000000009fc00 end:
000000000009fc00 type: 1
copy_e820_map() type is E820_RAM
copy_e820_map() start: 000000000009fc00 size: 0000000000000400 end:

000000001f72f800 type: 1
copy_e820_map() type is E820_RAM
copy_e820_map() start: 000000001f72f800 size: 0000000000000800 end:

00000000fed1a000 type: 2
copy_e820_map() start: 00000000fed1c000 size: 0000000000084000 end:
00000000feda0000 type: 2
What are these sanitize start, sanitize end, copy_e820_map() about?
Memory check?
After this, dmesg is almost same as in 2.6.19.2. But here is another
observation::
migration_cost=18 for 2.6.19.2
migration_cost=87 for 2.6.20-rc5
How does this parameter value impacts the kernel?
Lastly, this about Intel RNG:
For 2.6.19.2
intel_rng: FWH not detected
For 2.6.20-rc5
intel_rng: Firmware space is locked read-only. If you can't or
intel_rng: don't want to disable this in firmware setup, and if
intel_rng: you are certain that your system has a functional
intel_rng: RNG, try using the 'no_fwh_detect' option.
Is this a bug? Or, something wrong with my H/W?
