Arm Preparing The Linux Kernel For 128-bit Page Table Entries

[erek]

Moar Addressable Memory !!!!

“The current Linux kernel patches for Arm's FEAT_D128 are under a request for comments (RFC) flag. There are also some known limitations such as KVM, Kernel Address Sanitizer, and other select features not currently being supported with FEAT_D128.

Those interested in this 128-bit page table entries support for ARM can see the RFC patch series for all the details.”

Ok...I'm all for more ram and speed, etc. but I'm going to say it...64-bit allows up to 16 exabytes of memory. Is this really the time to start worrying about 128-bit??

The ai needs all the bits!

Page tables are used to map virtual addresses to physical addresses. They can be used for more than just dram.

We're still doing the bit wars? I'll get my Sega Genesis out. No wait, I converted it to a Neptune.
