# \[PATCH 33/44\] openrisc: remove arch-specific dma\_supported implementation - From: Christoph Hellwig \ - Date: 2017-06-08 13:28:35 - List: linux-arm-kernel - Page: https://ratatoskr.run/linux-arm-kernel/2017/06/5016091 - Thread: https://ratatoskr.run/linux-arm-kernel/2017/06/5016133/t.md ```text This implementation is simply bogus - hexagon only has a simple direct mapped DMA implementation and thus doesn't care about the address.
