Subject: [PATCH v7 12/27] cxl/mem: Prepare for early RCH dport component register setup
Date: Thu, 22 Jun 2023 15:55:08 -0500 [thread overview]
Message-ID: <20230622205523.85375-13-terry.bowman@amd.com> (raw)
In-Reply-To: <20230622205523.85375-1-terry.bowman@amd.com>
From: Robert Richter <rrichter@amd.com>
In order to move the RCH dport component register setup to cxl_pci the
base address must be stored in CXL device state (cxlds) for both
modes, RCH and VH. Store it in cxlds->component_reg_phys and use it
for endpoint creation.
