Date: Tue, 12 Dec 2017 20:14:35 +0100 [thread overview]
Message-ID: <20171212191435.GB1921@zrhn9910b> (raw)
Hello all,
i have a short question:
How are the bits (in brackets) calculated in the virtual memory map ?
for example the first line (=47 bits)
Virtual memory map with 4 level page tables:
0000000000000000 - 00007fffffffffff (=47 bits) user space, different per mm
hole caused by [47:63] sign extension
ffff800000000000 - ffff87ffffffffff (=43 bits) guard hole, reserved for hypervisor
Best regards
Damian
