From 3417f33e762bf7d4277031a655e3ad07e73ce0be Mon Sep 17 00:00:00 2001 From: George Sapountzis Date: Tue, 24 Oct 2006 12:03:04 -0700 Subject: drm: add flag for mapping PCI DMA buffers read-only. Add DRM_PCI_BUFFER_RO flag for mapping PCI DMA buffer read-only. An additional flag is needed, since PCI DMA buffers do not have an associated map.
