That seems rather limited compared to EAS in practice, since some EAS stations will relay appropriate alerts, and since EAS runs over both broadcast FM, AM, and TV stations.

I think most of these solutions probably predate 8051 and ST7 cores(which both have stack pointers) where I ran into them but reduced memory models are still pretty useful for them, due to the overhead vs RAM usually fitted. It's too l

This presentation is an overview of many different mitigations spanning ~27 years. Some are quite widely implemented. I'm less familiar with the newer stuff, but here's some I've run into. No-exec stacks: some UNIX machines,

RAMs on M1 are in separate die in the same package. This let's Apple make fewer die SKUs, as well as use differently optimize die processes. https://www.macrumors.com/2021/04/06/m1-mac-ram-and-ssd-upgr...

Not the commenter, but I'm a little sad ThinkPads didn't keep up. They have an ARM64 offering, but it's PlaySkool premium.

The one axis isn't instantaneous workload; it is queue length(work items not being handled by threads). The PID controller is finding a reasonable number of workers that handle the peak bursts without allowing the queue to get too long

ARM11 has an FPU. The FPU is particularly slow to copy back and forth to the integer registers. This the raspberry pi people support an ARM11 core with armhf ABI, albeit limited to the VFPv2 FPU instruction set.

With the continued development of specex attacks, having those features in a separate domain reduces the attack surface some, compared to sharing a core with attacker controlled code.

At first I didn't understand the input format, which seems to try and autodetect the units. When I enter 1e-3, I get 1ms past epoch start, but 1e-4 is 0ms past epoch start. And that isn't what I'd expect. Here's another

I think the worst offenders are the ones that use the measurement circuit to detect if you've started a measurement while the display is off.

An LR44 supplying 15 microamps will last more than 9 months before depleted. This base level of current draw obviously matters to different users differently.

The PA-RISC 1.1 ISA encoded specific implementation details that didn't age well, like the branch delay slot and instruction address queues. And required in-order memory accesses, because there wasn't support for cache coherent IO

It matters less often - it can still matter at the end of each write buffer. Larger write-buffers remove a lot of chances for this to happen. If the application can buffer the entire file or use sendfile, probably best to disable Nagle&#x27

Ideally large files would upload in MTU sized packets, which Nagle's algorithm will often give you, otherwise you may have a small amount of additional overhead at the boundary where the larger chunk may not be divisible into MTU sized

Ideally yes. Only last year did Clang 13 learn the 32-bit one. GCC doesn't understand either. I haven't checked clang for the 64-bit one.

by rsaxvc 4y ago
I haven't tested this, but on Arm32 platforms, this isn't a bad way to do it n some 32-bit machines. If the compiler recognizes the 32-bit approach and rbit is available, the 64-bit variant is usually 2 rbits with the registers sw
