[PATCH 0/5] cxl: Some preparation work for type2 accelerators support

From: Huang Ying
Date: Tue Oct 15 2024 - 02:58:25 EST


This series implement some preparation work for the type2 accelerators
support.

We have tested the series with cxl_test via mocking a type2
accelerator as in [1]. Because we need more type2 accelerators
support to simulate a type2 device, we don't include the cxl_test
patch in the series.
