Subject: [PATCH v3 03/19] memory: Allow to store the PASID in IOMMUTLBEntry
Date: Fri, 21 Feb 2025 08:07:32 +0000 [thread overview]
Message-ID: <20250221080331.186285-4-clement.mathieu--drif@eviden.com> (raw)
In-Reply-To: <20250221080331.186285-1-clement.mathieu--drif@eviden.com>
From: Clement Mathieu--Drif <clement.mathieu--drif@eviden.com>
This will be useful for devices that support ATS
and need to store entries in an ATC (device IOTLB).
