Subject: [PATCH v3 02/15] PCI/AER: Rename AER driver's interfaces to also indicate CXL PCIe port support
Date: Wed, 13 Nov 2024 15:54:16 -0600 [thread overview]
Message-ID: <20241113215429.3177981-3-terry.bowman@amd.com> (raw)
In-Reply-To: <20241113215429.3177981-1-terry.bowman@amd.com>
The AER service driver already includes support for CXL restricted host
(RCH) downstream port error handling. The current implementation is based
on CXL1.1 using a root complex event collector.
Rename function interfaces and parameters where necessary to include
virtual hierarchy (VH) mode CXL PCIe port error handling alongside the RCH
handling.[1] The CXL PCIe port error handling will be added in a future
patch.
Limit changes to renaming variable and function names. No functional
changes are added.
[1] CXL 3.1 Spec, 9.12.2 CXL Virtual Hierarchy
