Subject: [PATCH v2 11/13] media: iris: Select DMA_CONTEXT_BUS to create firmware device
Date: Thu, 23 Apr 2026 18:59:40 +0530 [thread overview]
Message-ID: <20260423-glymur-v2-11-0296bccb9f4e@oss.qualcomm.com> (raw)
In-Reply-To: <20260423-glymur-v2-0-0296bccb9f4e@oss.qualcomm.com>
Iris need a firmware device to enable secure PAS (peripheral
authentication service) support in case of non-Gunyah. This device
requires its own IOMMU context for memory isolation. The generic
dma-context-bus provides the infrastructure to create the device and
configure its firmware stream ID.
Select DMA_CONTEXT_BUS to ensure this bus is available when
VIDEO_QCOM_IRIS is enabled.
