From 72caa48c82e4334d3292185dbadf758d2dd14c16 Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Wed, 28 Feb 2007 15:14:08 +1100 Subject: nouveau: intrusive drm interface changes graphics objects: - No longer takes flags/dmaobj parameters, requires some major changes to the ddx to setup the object through the FIFO. This change is likely to cause breakages on some cards (tested on NV05,NV28,NV35, NV40 and NV4E). dma objects: - now takes a "class" parameter, not really used yet but we may need it at some point. - parameters are checked, so clients can't randomly create DMA objects pointing at whatever they feel like. misc: - Added FB_SIZE/AGP_SIZE getparams - Read PFIFO_INTR in PFIFO irq handler, not PMC_INTR - Dump PGRAPH trap info on PGRAPH_INTR_NOTIFY if NSOURCE isn't NOTIFICATION_PENDING. --- shared-core/nouveau_drm.h | 29 +++--- shared-core/nouveau_drv.h | 13 +-- shared-core/nouveau_fifo.c | 9 +- shared-core/nouveau_irq.c | 54 ++++++---- shared-core/nouveau_mem.c | 4 +- shared-core/nouveau_object.c | 234 ++++++++++++++++++++++++------------------- shared-core/nouveau_reg.h | 8 ++ shared-core/nouveau_state.c | 13 ++- shared-core/nv40_graph.c | 1 + 9 files changed, 213 insertions(+), 152 deletions(-) (limited to 'shared-core') diff --git a/shared-core/nouveau_drm.h b/shared-core/nouveau_drm.h index 0f11c43a..8a1964ed 100644 --- a/shared-core/nouveau_drm.h +++ b/shared-core/nouveau_drm.h @@ -25,6 +25,8 @@ #ifndef __NOUVEAU_DRM_H__ #define __NOUVEAU_DRM_H__ +#define NOUVEAU_DRM_HEADER_PATCHLEVEL 4 + typedef struct drm_nouveau_fifo_alloc { int channel;
