- Enabling ARMv8 on Raspberry Pi 3 B
Is it even worth switching from ARMv7 to ARMv8 Various software cited to require ARMv8 includes CockroachDB, MongoDB (if accessing >2 GB), the Dolphin emulator, and OpenMW However, likewise you'll lose out on other features or programs that may be less-supported with a 64-bit kernel (e g gaming with brcmEGL + dispmanx) arm_control=0x200
- aarch64 or armv8 with Arch on a Raspberry Pi 4?
I installed arch on my raspberry pi 4 based on the instructions from the arch linux arm site, expecting to get an aarch64 install, or some variant of armv8 Instead what I got was an install of armv7 as best as I can tell, presumably 32 bit, although I am not certain
- Why raspberry pi 4b claims that its processor is armv7l when in . . .
The Raspberry Pi 3 and 4 have 64-bit CPUs However, Raspbian is a 32-bit operating system, so that SD card images work on all Pi models Depending on where you're looking, the Pi will report armv6 or armv7 (usually armv7) although it's actually running in armv6 userland, and despite the hardware is actually armv8
- Raspberry Pi 3 and 64-bit kernel, differences between armv7 and armv8
Again, nope, not without a lot of hacking, but because the pi kernel is not stock, not because ARMv7 doesn't work on ARMv8 (currently the Pi 2 and 3 use the same kernel) – goldilocks Commented Jun 7, 2016 at 14:58
- How do I see which ARM CPU version I have? - raspbian
At a command prompt, type cat proc cpuinfo to view CPU information The ARM11 chips use version 6 of the ARM instruction set, ARMv6
- Correct cross-compilation options to run binary on Raspberry 3 model B
@AlphaParticle ARMv8 only refers to the hardware revision, it does not imply a bitness The ARMv8-A Cortex-A53 hardware supports both the AArch64 and AArch32 architectures You seem to be using a 32-bit operating system, so you need a 32-bit toolchain, which is armv8-rpi3-linux-gnueabihf
- Raspberry Pi 4 Target Architecture Cross Linux From Scratch
Floating Point Unit version - neon-fp-armv8 Is this the correct triplet? If not, what is it or how do I go about finding it out? I got the FPU version from a post on Stackoverflow - can anyone confirm if this is correct? I believe the architecture, ARM architecture and floating point support are correct Please correct me if they are wrong
- How do I read the cpuid in aarch64 asm? - Raspberry Pi Stack Exchange
What is the equivalent for that in aarch64 armv8 syntax? Note: I'm trying to detect if I'm running on a RPi3, RPi4 or some other arm board This is before parsing the device tree so that isn't an alternate option
