maxdsiz value of 0x20000000. What value does this actually mean?

[Joe Profaizer]

I'm trying to compare kernel parameters on two different systems. One system has a maxdsiz value of 0x20000000 and the other system has a value of 2063835136.

I need to know what 0x20000000 equates to.

Thanks...

Hi Joe,

It's in hexadecimal & would equate to
536870912 in decimal

Rgds,

this value is in hexadecimal so 0x20000000 is equal to 536870912

Decimal value is 536870912 (512 MB)

Hi,

this is HEX

20000000 in HEX = 536870912 in Dec

536870912 / 1024 /1024 = 512kb

So your system has 512kb configured for maxdsiz.

This is a nice overview about the configurable parameters and gives some hints about the ranges:

Best regards, Hartmut

Hi Joe,

An easy way to convert the numbers is using adb. For instance, to convert hex to decimal use :

# echo 0x20000000=D | adb

To go the other way :

# echo 0d2063835136=X | adb

You can convert to octal too, although this is required less frequently. See the adb manpage for other useful features.

cheers,

James.
