Subject: [PATCH v6 10/14] riscv: Enable DMA_RESTRICTED_POOL in defconfig
Date: Thu, 1 Oct 2026 10:52:21 +0530 [thread overview]
Message-ID: <20261001052243.3042627-11-mayuresh.chitale@oss.qualcomm.com> (raw)
In-Reply-To: <20261001052243.3042627-1-mayuresh.chitale@oss.qualcomm.com>
From: Anup Patel <anup.patel@oss.qualcomm.com>
The RISC-V ramsink trace component may have implementation specific
restrictions such that the component can only write trace data in
particular parts of DRAM.
Enable DMA_RESTRICTED_POOL in the defconfig so that dma_alloc_*()
and dma_free_*() APIs work for devices with DMA address restrictions.
Signed-off-by: Anup Patel <anup.patel@oss.qualcomm.com>
