Architectures

This page documents CPU architectures supported by spksrc and Synology devices.

Overview

Synology NAS devices use various CPU architectures. spksrc cross-compiles packages for each supported architecture.

Architecture Naming

Architectures are identified as <arch>-<tcversion> where:

  • <arch> - CPU architecture identifier
  • <tcversion> - DSM toolchain version (e.g., 7.2, 6.2)

Example: x64-7.2 = Intel 64-bit, DSM 7.2 toolchain

Current Architectures (DSM 7.x)

Architecture CPU Family Description Example Models
x64 Intel 64-bit x86-64 processors DS923+, RS1221+
aarch64 ARM 64-bit ARM Cortex-A57 (Marvell) DS220+, DS720+, DS920+
armv8 ARM 64-bit ARM Cortex-A55 (Realtek) DS223, DS423, RS422+

Legacy Architectures (DSM 6.x)

Architecture CPU Family Description Example Models
x86 Intel 32-bit x86 processors DS216play
armv7 ARM 32-bit Various ARM v7 DS218j, DS418
armv7l ARM 32-bit Low-end ARM v7 DS115j
qoriq QorIQ Freescale QorIQ DS215j
comcerto2k Comcerto Mindspeed Comcerto DS414j
ppc853x PowerPC PowerPC 85xx DS109j

Architecture Groups

spksrc defines groups for conditional logic:

64-bit Architectures

64bit_ARCHS = x64 aarch64 armv8

32-bit Architectures

32bit_ARCHS = x86 armv7 armv7l qoriq comcerto2k ppc853x

ARM Architectures

ARM_ARCHS = aarch64 armv8 armv7 armv7l
ARMv7_ARCHS = armv7 armv7l
ARMv8_ARCHS = aarch64 armv8

Intel Architectures

x64_ARCHS = x64
x86_ARCHS = x86

Toolchain Versions

Version DSM Status
7.2 DSM 7.2+ Current
7.1 DSM 7.0-7.1 Supported
6.2 DSM 6.2 Supported
6.1 DSM 6.0-6.1 Limited
5.2 DSM 5.2 Legacy

Using Architecture Conditions

In Makefiles

# Only for 64-bit
ifeq ($(findstring $(ARCH),$(64bit_ARCHS)),$(ARCH))
CONFIGURE_ARGS += --enable-64bit
endif

# Exclude 32-bit
UNSUPPORTED_ARCHS = $(32bit_ARCHS)

# ARM-specific
ifeq ($(findstring $(ARCH),$(ARM_ARCHS)),$(ARCH))
CONFIGURE_ARGS += --enable-neon
endif

In local.mk

# Build only for these architectures
SUPPORTED_ARCHS = x64-7.2 aarch64-7.2

Finding Your Architecture

From DSM

  1. Log into DSM web interface
  2. Go to Control Panel > Info Center > General
  3. Note the CPU Model and Model Name
  4. Look up in the tables above

From SSH

# Show kernel architecture
uname -m

# Show Synology platform (maps to architecture)
cat /proc/syno_platform

# Show CPU architecture details
cat /proc/syno_cpu_arch

From Package Download

The package download page at packages.synocommunity.com automatically detects your NAS architecture when accessed from the device.
