Linux 6.10 x86 Instruction Decoder Prepares For APX & Other New Intel Instructions

([Intel] 5 Hours Ago Performance Events)


The performance events updates were submitted today for the ongoing Linux 6.10 kernel merge window. This pull adds support for [1]Advanced Performance Extensions (APX) and other new Intel CPU instructions to the x86 instruction decoder.

The Linux kernel's x86 instruction decoder is used for decoding kernel instructions, user-space probes, and the perf tools with the Intel processor Trace decoding. With Linux 6.10 the initial Advanced Performance Extensions (APX) instructions are supported along with Intel [2]Key Locker instructions, JMPABS for 64-bit absolute direct jump, and various other newer Intel CPU instructions.

Abou Ben Adhem (may his tribe increase!)
Awoke one night from a deep dream of peace,
And saw, within the moonlight in his room,
Making it rich, and like a lily in bloom,
An angel writing in a book of gold.
Exceeding peace had made Ben Adhem bold,
And to the presence in the room he said,
"What writest thou?" The vision raised its head,
And with a look made of all sweet accord,
Answered, "The names of those who love the Lord."
"And is mine one?" said Abou. "Nay not so,"
Replied the angel. Abou spoke more low,
But cheerly still; and said, "I pray thee then,
Write me as one that loves his fellow-men."
The angel wrote, and vanished. The next night
It came again with a great wakening light,
And showed the names whom love of God had blessed,
And lo! Ben Adhem's name led all the rest.
-- James Henry Leigh Hunt, "Abou Ben Adhem"
