Phoronix: Intel Arrow Lake Enablement For Linux Looking To Get Underway

While for many months now Intel's open-source driver engineers have been busy getting Meteor Lake Linux support squared away and there has even been some Lunar Lake activity for the Linux kernel going back to 2021, it looks now like their Arrow Lake enablement will be getting underway...

It is always good to see these new hardware support added. But I am worried that the distributions are not removing the deprecated features while adding the new hardware feature from kernel. For example, Ubuntu still enables Intel SGX features in all kernels while it is deprecated in 12th and 13th gen and TDX features while it is not available in any new generation yet. There are many other examples of bloating the Linux kernel. These should be at least modulerized.

This is the difference after irrelevant features removed in a custom kernel

-rw-r--r--  1 root root   7875008 Apr  8 12:29 vmlinuz-6.2.10-mirage

That's why people like me compile their own custom Kernel for ages now which also gives you the opportunity for using march=native and some other compiler tuning.

Has anyone heared if Arrow Lake brings back AVX-512 support?
