Subject: [PATCH v2 18/21] cxl: Move identify and partition query from pci probe to port probe
Date: Mon, 27 Mar 2023 14:45:54 -0700 [thread overview]
Message-ID: <167995355442.2857312.7640440102093572590.stgit@djiang5-mobl3> (raw)
In-Reply-To: <167995336797.2857312.539473939839316778.stgit@djiang5-mobl3>
Move the enumeration of device capacity to cxl_port_probe() from
cxl_pci_probe(). The size and capacity information should be read
after cxl_await_media_ready() so the data is valid.
Fixes: 5e2411ae8071 ("cxl/memdev: Change cxl_mem to a more descriptive name")
