[PATCH v2 07/12] hw/cxl: Pass CXLComponentState to cache_mem_ops
Posted by Jonathan Cameron via 10 months ago
From: Li Zhijian <lizhijian@fujitsu.com>

cache_mem_ops.{read,write}() interprets opaque as
CXLComponentState(cxl_cstate) instead of ComponentRegisters(cregs).

Fortunately, cregs is the first member of cxl_cstate, so their values are
the same.

Fixes: 9e58f52d3f8 ("hw/cxl/component: Introduce CXL components (8.1.x, 8.2.5)")
