Subject: [PATCH kernel 4/4] pci: Define Integrity and Data Encryption (IDE) extended capability
Date: Thu, 1 Feb 2024 17:02:28 +1100 [thread overview]
Message-ID: <20240201060228.3070928-5-aik@amd.com> (raw)
In-Reply-To: <20240201060228.3070928-1-aik@amd.com>
PCIe 6.0 introduces the "Integrity & Data Encryption (IDE)" feature which
adds a new capability with id=0x30.
Add the new id to the list of capabilities.
Signed-off-by: Alexey Kardashevskiy <aik@amd.com>

This only adds an id. The rest is here:

Not sure how much of that we want in the Linux.
