From de60977c6a41b6de65e74918024c150e44311940 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Philippe=20Mathieu-Daud=C3=A9?= Date: Wed, 15 Dec 2021 22:18:19 +0100 Subject: [PATCH 10/25] pci: Let pci_dma_rw() take MemTxAttrs argument MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Let devices specify transaction attributes when calling pci_dma_rw(). Keep the default MEMTXATTRS_UNSPECIFIED in the few callers.
