profiles: Nuke cpu_flags_x86_mpx, #588632 Remove the mpx flag from CPU_FLAGS_X86. Since mpx has memory and performance costs, this is not a flag users expect to have automatically enabled based on CPU abilities. profiles/arch/amd64/use.mask | 1 - profiles/arch/x86/use.mask | 1 - profiles/base/use.mask | 1 - profiles/desc/cpu_flags_x86.desc | 1 - 4 files changed, 4 deletions(-) diff --git a/profiles/arch/amd64/use.mask b/profiles/arch/amd64/use.mask index acdbc57..2fa9867 100644 --- a/profiles/arch/amd64/use.mask +++ b/profiles/arch/amd64/use.mask @@ -173,7 +173,6 @@ -cpu_flags_x86_fma4 -cpu_flags_x86_mmx -cpu_flags_x86_mmxext --cpu_flags_x86_mpx -cpu_flags_x86_padlock -cpu_flags_x86_popcnt -cpu_flags_x86_sse diff --git a/profiles/arch/x86/use.mask b/profiles/arch/x86/use.mask index bb9bd58..e9c6177 100644 --- a/profiles/arch/x86/use.mask +++ b/profiles/arch/x86/use.mask @@ -140,7 +140,6 @@ -cpu_flags_x86_fma4 -cpu_flags_x86_mmx -cpu_flags_x86_mmxext --cpu_flags_x86_mpx -cpu_flags_x86_padlock -cpu_flags_x86_popcnt -cpu_flags_x86_sse diff --git a/profiles/base/use.mask b/profiles/base/use.mask index f3ee065..5d34ee4 100644 --- a/profiles/base/use.mask +++ b/profiles/base/use.mask @@ -101,7 +101,6 @@ cpu_flags_x86_fma3 cpu_flags_x86_fma4 cpu_flags_x86_mmx cpu_flags_x86_mmxext -cpu_flags_x86_mpx cpu_flags_x86_padlock cpu_flags_x86_popcnt cpu_flags_x86_sse diff --git a/profiles/desc/cpu_flags_x86.desc b/profiles/desc/cpu_flags_x86.desc index 4a12cc6..7aaab7e 100644 --- a/profiles/desc/cpu_flags_x86.desc +++ b/profiles/desc/cpu_flags_x86.desc @@ -15,7 +15,6 @@ fma3 - Use the Fused Multiply Add 3 instruction set ([fma] in cpuinfo) fma4 - Use the Fused Multiply Add 4 instruction set mmx - Use the MMX instruction set mmxext - Use the Extended MMX instruction set (a subset of SSE) ([mmxext] or [sse] in cpuinfo) -mpx - Use Memory Protection Extensions (MPX) padlock - Use VIA padlock instructions ([phe] in cpuinfo) popcnt - Enable popcnt instruction support ([abm] or [popcnt] in cpuinfo) sse - Use the SSE instruction set
