kees@fosstodon.orgHere's how to enable the kernel Memory Tagging Extension (#MTE) on the Pixel 8:
adb shell setprop arm64.memtag.bootctl memtag,memtag-kernel
I'm so happy there's real-world hardware finally available to provide mitigations against linear buffer overflows and many types of use-after-free flaws.
More details here:

Soju is Korea's traditional distilled spirit.
It's clear, neutral spirit usually distilled from grains. The taste is sometimes bitter and sometimes sweet ;)
Most of time koreans drink Soju or beer when drinking socially. And it's also used to measure one's drinking limit (like, "how many bottles of Soju can you drink?")

Whiskey's bit expensive to drink enough (TM) :P
I'd rather drink Soju sir (about $1~$3 per bottle)

Why do we have two different specifications about firmware interface (UEFI and ACPI)?
Why can't UEFI (Unified EFI) unify everything :/

How do memory controllers "map" device resources (memory or registers) with address spaces assigned via PCI BARs into system memory address space? Is there a FPGA device in it the controller?
This whole question may be wrong as Iack some knowledge about it.

Hmm what's the point of PCIe Root Complex-Integrated Endpoints (RCiEP) rather than Endpoints connected to Root Port

In the ACPI specification; the character representing ACPI root namespace ('\') seems to be escaped (' and \') and looks like this.
How have people been reading this?
