Subject: [PATCH 0/2] iommu/amd: Interrupt handling improvements
Date: Fri, 9 Jun 2023 10:20:23 +0000 [thread overview]
Message-ID: <20230609102025.6498-1-vasant.hegde@amd.com> (raw)
AMD IOMMU has three different logs/interrupts (Event, PPR and GA).
Currently, the IOMMU driver consolidates interrupts for all three logs to
a single interrupt. This could become a bottleneck when enable GA and PPR
logs simultaneously. Hence separate these interrupt to prevent potential
performance issue.
This patch applies on top of cleanup series:
