|
|
+This property is used when booting with CONFIG_RANDOMIZE_BASE as the
|
|
|
+entropy used to randomize the kernel image base address location. Since
|
|
|
+it is used directly, this value is intended only for KASLR, and should
|
|
|
+not be used for other purposes (as it may leak information about KASLR
|
|
|
+offsets). It is parsed as a u64 value, e.g.
|
|
|
+
|
|
|
+/ {
|
|
|
+ chosen {
|
|
|
+ kaslr-seed = <0xfeedbeef 0xc0def00d>;

|
|
|
+mode) when EFI_RNG_PROTOCOL is supported, it will be overwritten by
|
|

+the Linux EFI stub (which will populate the property itself, using
|
|
|
+EFI_RNG_PROTOCOL).
