Hi all,

The incoming kernel mm patch will save ~1.6% Memory for 1G hugepage
and ~1.2% for 2M hugepage, which is a good news for DPDK.
https://lore.kernel.org/linux-doc/20210510030027.56044-5-songmuc...@bytedance.com/
if you run a server with 1TB Dram, you can save ~16G.

Hi Bruce,
I look into current IOAT PMD. I found that looks only support the
latest DSA device which is part of SPR(Please correct me if I'm wrong).
However, there still is lots existing CPU that support previous CBDMA
Intel Quick-DATA technology. SPDK enable those device with uio.

PMU is kind of MSR. Precisely , that's MSR per core.
All MSR reading will lead to IPI(Please reference the kernel
implementation of MSR driver). The IPI will disturb the DPDK application
because the userspace/kernel context switch, which has impact to the
tail latency.

Hi All,
I try to build DPDK with debug build-type but the building process is
failed becuase of AVX512 code from librte-acl. The release build type
is fine. Hence, I dig a bit into the avx512 enabling logic of meson.
I found the main logic is implemented inside binutils-avx512-check.
