isa-support package

isa-support 15 source package in Ubuntu

Changelog

isa-support (15) unstable; urgency=high

  * Bug fix: "version 14 fails to install where version 13 installs fine
    due to different binary capitalization: test-sse3 vs test-SSE3",
    thanks to Axel Beckert (Closes: #1019556).
  * Install qemu-bad-ISA/qemu-good-ISA in order to allow test

Binary packages built by this source

armv8-support: CPU feature checking - require ARMv8

 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 ARMv8 and refuses to install
 on unsupported hardware.
 .
 ARMv8 (not to be confused with product family ARM8) introduced a large
 number of ISA enhancements. It is not guaranteed by the architecture
 baseline, but is available for newer armel machines (including CPUs that
 support armhf) since the Cortex-A product family, including Cortex-A32, as
 well as all arm64 processors. Boards include the Raspberry Pi 3 and 4.

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

 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 neon and refuses to install
 on unsupported hardware.
 .
 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.

sse2-support: CPU feature checking - require SSE2

 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 SSE2 and refuses to install
 on unsupported hardware.
 .
 Streaming SIMD Extensions (SSE) is a single instruction, multiple data
 (SIMD) instruction set extension.
 .
 SSE2 was an incremental upgrade to SSE intended to fully replace the earlier
 MMX instruction set. It is available on processors from Pentium 4 onward,
 including all 64-bit capable ones, but not on Pentium 3, Athlon XP, Via C3,
 Quark, or older processors.

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.

sse4.1-support: CPU feature checking - require SSE4.1

 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 SSE4.1 and refuses to install
 on unsupported hardware.
 .
 Streaming SIMD Extensions (SSE) is a single instruction, multiple data
 (SIMD) instruction set extension.
 .
 SSE4.1 added a dot product instruction and additional integer instructions.
 It is available on Intel processors since Penryn (circa 2008), but notably
 not on anything AMD until the Bulldozer (15h, in 2011) and Jaguar (16h, in
 2013) families.

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.
