Extensions to be retrieved via unix.RISCV_HWPROBE_KEY_IMA_EXT_0 Note: This list is declared here since the one in golang.org/x/sys/unix/ztypes_linux_riscv64.go is not complete, and only contains the values up to RISCV_HWPROBE_EXT_ZIHINTPAUSE. Some of the constants missing in that file are required for RVA23, e.g. Zcmop

Variables ¶
var IsISASupportedByCPU = isISASupportedByCPU
IsISASupportedByCPU takes the name of an ISA and checks if it is supported by the CPU and kernel snapd is currently running on using architecture-specific code. Returns nil when the ISA is supported, or an explicit error otherwise.
var KernelVersion = osutil.KernelVersion
var RISCVHWProbe = func(pairs []RISCVHWProbePairs, set *CPUSet, flags uint) (err error) { return nil }
Re-defined to allow mocking this

Define extensions list
The value of the "Required" field for all the entries is taken from RVA23 Profiles Specification, Version 1.0, 2024-10-17. The comments at the end of the line explain why the item is marked as Required.
Functions ¶
func DpkgArchitecture ¶
func DpkgArchitecture() string
DpkgArchitecture returns the debian equivalent architecture for the currently running architecture.
If the architecture does not map any debian architecture, the GOARCH is returned.
func DpkgKernelArchitecture ¶
func DpkgKernelArchitecture() string
DpkgKernelArchitecture returns the debian equivalent architecture for the current running kernel. This is usually the same as the DpkgArchitecture - however there maybe cases that you run e.g. a snapd:i386 on an amd64 kernel.
func IsRISCVISASupported ¶
IsRISCVISASupported takes the name of a RISCV64 ISA, gathers the list of extensions supported by the running platform, and verifies if all extensions required for compliance with the input ISA are supported. If they are, nil is returned. Otherwise, the missing requirement is returned.
Currently, only support for RVA23 can be checked for.
func IsSupportedArchitecture ¶
IsSupportedArchitecture returns true if the system architecture is in the list of architectures.
func SetArchitecture ¶
func SetArchitecture(newArch ArchitectureType)
SetArchitecture allows overriding the auto detected Architecture
Types ¶
type ArchitectureType ¶
type ArchitectureType string
ArchitectureType is the type for a supported snappy architecture
type RISCVHWProbePairs ¶
Re-defined like this because Mock functions have been moved to export_test.go
