Booting Linux flavors which do not support 48-bit VA (< Linux 3.18)
|
|
-------------------------------------------------------------------
|
|
One needs to use appropriate bootargs to boot Linux flavors which do
|
|
not support 48-bit VA (for e.g. < Linux 3.18) by appending mem=2048M, as shown
|
|
below:
|
|
|
|
=> setenv bootargs 'console=ttyS1,115200 root=/dev/ram
|
|
earlycon=uart8250,mmio,0x21c0600,115200 default_hugepagesz=2m hugepagesz=2m
|
|
hugepages=16 mem=2048M'
