Details

Features lists the CPU features of this logical ARM processor as explained in this StackExchange Thread.
For MIPS this is in options-implemented, for ATOM this is in flags.

Features supported by the ARM core of a Puma SoC:

edsp       Enhanced DSP extensions
fastmult   32×32→64-bit multiplication
half       Half-word loads and stores
java       Jazelle Java bytecode accelerator (Puma only)
swp        SWP instruction (atomic read-modify-write)
thumb      Thumb (16-bit instruction set)

Additionally in Dakota and BCM63:

evtstrm    Kernel event stream using generic architected timer (not in BCM63)
idiva      SDIV and UDIV hardware division in ARM mode
idivt      SDIV and UDIV hardware division in Thumb mode
lpae       Large Physical Address Extension (>4GB physical memory on 32-bit architecture)
neon       Advanced SIMD/NEON (asimd on AArch64 older Kernels)
tls        TLS register
vfp        VFP (early SIMD vector floating point instructions)
vfpd32     VFP with 32 D-registers
vfpv3      VFP version 3
vfpv4      VFP version 4 with fast context switching

Additionally in Maple and Hawkeye:

aes        Hardware-accelerated AES (secret-key cryptography)
crc32      Hardware-accelerated CRC-32
pmull      64×64→128-bit F2m multiplication (for GCM mode of authenticated encryption)
sha1       Hardware-accelerated SHA-1
sha2       Hardware-accelerated SHA-256

Dependencies

Daily updated index of all dependencies of this property. Last update: GMT.
A ** in the Mod column marks info from Supportdata2 probes, which will always stay incomplete.
A - in the Mod column marks manual research, the Firmware then shows where the Object occurs, not the Relation.

Model-Matrix

Daily updated index of the presence, path and size of this property for each model. Last update: 2024-04-19 04:27 GMT.
Showing all models using this property. Click any column header (click-wait-click) to sort the list by the respective data.
The (main/scrpn/boot/arm/prx/atom) label in the Model column shows which CPU is meant for models with multiple Linux instances.
Note that this list comes from Supportdata2 probes, which can have arbitrary settings and come from different firmware versions.
It doesn't say much if a model is not listed here. It may be a missing supportdata2 file or just a disabled feature.

Help Supportdata2

The data in this article is incomplete since it was manually collected using the Supportdata2 project.

Unlike the Supportdata-Probes which have been collected for years Supportdata2 is brand new and only has a few probes.
If you have access to a shell then please help to extend the Supportdata2 collection to improve this data.

It's easy and it's done in minutes. Please send created data as an Email attachment to the address listed here. Thanks!
