I highly doubt the kernel runtime decompression takes 8 seconds, let alone 27 seconds.
A kernel image is usually ~ 5M compressed. There is no way...

I don't get the difference between this and the already existing arch optimized implementations?
Per-cpu type function optimizations? Sounds nice...

I don't care much for Fraunhofer or any other encoder/decoder developer.
They are usually so full of shit (and their code is too) that it's not...

[milkylainen]

And here I was thinking that kernel-folk was on a killing spree towards anything older than their last generation of machines...

Sorry. But that's just stupid. Doing high volume GPIO-switching from userspace using sysfs...
I see these tendencies all over the place. "I...

Not FGKASLR. FGKASLR is fully understandable. You're rewriting the layout of your code.
So performance will most likely suffer, for a bunch of reasons....

[milkylainen]

I'm surprised KASLR has any impact whatsoever on performance.
I'm curious if this is test variability since KASLR actually does randomize stuff...

Just the sheer engineering keeping the old turd afloat...

I remember when cpuinfo features was a oneliner. Now it's like a novel...

Since the A53 most likely has a branch predictor, then it most certainly is in the class of "speculative execution" pipelines.
Branch...

Pointless in speculating if AMD has a swiss cheese state.
And speculations does not change the current state of things.
Intel rightly deserves...

"the final security gap currently enjoyed by unprivileged users on multi-user systems"

I am willing to bet against that. Any takers?...

[milkylainen]

Seems that "Patch-Tuesday" is a contagious disease after all...

[milkylainen]

Why the hell not? Just because you can't see a win?
Every code and every application is not "new and shiny", especially in the embedded...

Since the opspace is unlimited I can pretty much guarantee really interesting fuzzed opspace bugs.
I suspect some really interesting "knocking"...

"Was not hurting performance"

Yes. Because, you know, who uses databases and needs random numbers anyway?
Fucking epic Intel....

[milkylainen]

Indeed. Broken hardware with broken ass solutions which we barely understand the consequences of....
