Binary packages built by this source
- isa-support: CPU feature checking - common back-end
The packages in the isa-support family probe for microprocessor Instruction
Set Architecture features such as SSE3. By refusing to install on machines
lacking a required feature, they allow ISA requirements to be handled in
terms of package dependencies.
.
This package provides the feature-probing infrastructure. To assert a CPU
requirement, other packages can pre-depend on one of the individual
feature-specific packages:
.
sse2-support, sse3-support, sse4.2-support, altivec-support, neon-support,
armv6-support, armv7-support, armv8-support, vfp-support, vfpv2-support,
vfpv3-support
- isa-support-dbgsym: debug symbols for isa-support
- neon-support: CPU feature checking - require neon

.
This is a mostly dummy package which checks for neon and refuses to install
on unsupported hardware.

Neon, also known as MPE (Media Processing Engine) or Advanced SIMD, is a
combined 64- and 128-bit SIMD instruction set that provides standardised
acceleration for media and signal processing applications. It is available
on the vast majority of armhf devices but not guaranteed before the 64-bit
capable ARMv8.
- sse3-support: CPU feature checking - require SSE3
The packages in the isa-support family probe for microprocessor Instruction
Set Architecture features such as SSE3. By refusing to install on machines
lacking a required feature, they allow ISA requirements to be handled in
terms of package dependencies.
.
This is a mostly dummy package which checks for SSE3 and refuses to install
on unsupported hardware.
.
Streaming SIMD Extensions (SSE) is a single instruction, multiple data
(SIMD) instruction set extension.
.
SSE3, also called PNI (Prescott New Instructions), is an incremental upgrade
to SSE2, adding a handful of new operations useful for processing media. It
is available on almost any 64-bit-capable processor except for some early
AMD models (Sledgehammer and Clawhammer), but is not available on most
32-bit-only hardware.
- sse4.2-support: CPU feature checking - require SSE4.2
The packages in the isa-support family probe for microprocessor Instruction
Set Architecture features such as SSE3. By refusing to install on machines
lacking a required feature, they allow ISA requirements to be handled in
terms of package dependencies.
.
This is a mostly dummy package which checks for SSE4.2 and refuses to install
on unsupported hardware.
.
SSE4.2 added string and text processing instructions that perform character
searches and comparison on two operands of 16 bytes at a time. It is
available on Intel processors since Nehalem (circa 2008), but notably not
on anything AMD until the Bulldozer (15h, in 2011) and Jaguar (16h, in
2013) families.
