From 695599f18d907bb277805581bbe208b0e083e7d9 Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Sun, 24 Jun 2007 19:03:35 +1000 Subject: nouveau: Nuke DMA_OBJECT_INIT ioctl (bumps interface to 0.0.7) For various reasons, this ioctl was a bad idea. At channel creation we now automatically create DMA objects covering available VRAM and GART memory, where the client used to do this themselves. However, there is still a need to be able to create DMA objects pointing at specific areas of memory (ie. notifiers). Each channel is now allocated a small amount of memory from which a client can suballocate things (such as notifiers), and have a DMA object created which covers the suballocated area. The NOTIFIER_ALLOC ioctl exposes this functionality. --- shared-core/nouveau_drm.h | 28 ++++++++++++++++------------ 1 file changed, 16 insertions(+), 12 deletions(-) (limited to 'shared-core/nouveau_drm.h') diff --git a/shared-core/nouveau_drm.h b/shared-core/nouveau_drm.h index 1e7322e0..0758991a 100644 --- a/shared-core/nouveau_drm.h +++ b/shared-core/nouveau_drm.h @@ -25,9 +25,12 @@ #ifndef __NOUVEAU_DRM_H__ #define __NOUVEAU_DRM_H__ -#define NOUVEAU_DRM_HEADER_PATCHLEVEL 6 +#define NOUVEAU_DRM_HEADER_PATCHLEVEL 7 typedef struct drm_nouveau_fifo_alloc { + uint32_t fb_ctxdma_handle; + uint32_t tt_ctxdma_handle; + int channel; uint32_t put_base; /* FIFO control regs */ @@ -36,29 +39,30 @@ typedef struct drm_nouveau_fifo_alloc { /* DMA command buffer */ drm_handle_t cmdbuf; int cmdbuf_size; + /* Notifier memory */ + drm_handle_t notifier; + int notifier_size; } drm_nouveau_fifo_alloc_t; -typedef struct drm_nouveau_object_init { +typedef struct drm_nouveau_grobj_alloc { int channel; uint32_t handle; int class; } -drm_nouveau_object_init_t; +drm_nouveau_grobj_alloc_t; #define NOUVEAU_MEM_ACCESS_RO 1 #define NOUVEAU_MEM_ACCESS_WO 2 #define NOUVEAU_MEM_ACCESS_RW 3 -typedef struct drm_nouveau_dma_object_init { +typedef struct drm_nouveau_notifier_alloc { int channel; uint32_t handle; - int class; - int access; - int target; + int count; + uint32_t offset; - int size; } -drm_nouveau_dma_object_init_t; +drm_nouveau_notifier_alloc_t; #define NOUVEAU_MEM_FB 0x00000001 #define NOUVEAU_MEM_AGP 0x00000002 @@ -68,7 +72,7 @@ drm_nouveau_dma_object_init_t; #define NOUVEAU_MEM_USER_BACKED 0x00000020 #define NOUVEAU_MEM_MAPPED 0x00000040 #define NOUVEAU_MEM_INSTANCE 0x00000080 /* internal */ - +#define NOUVEAU_MEM_NOTIFIER 0x00000100 /* internal */ typedef struct drm_nouveau_mem_alloc { int flags; int alignment; @@ -141,8 +145,8 @@ typedef struct drm_nouveau_sarea { drm_nouveau_sarea_t; #define DRM_NOUVEAU_FIFO_ALLOC 0x00 -#define DRM_NOUVEAU_OBJECT_INIT 0x01 -#define DRM_NOUVEAU_DMA_OBJECT_INIT 0x02 +#define DRM_NOUVEAU_GROBJ_ALLOC 0x01 +#define DRM_NOUVEAU_NOTIFIER_ALLOC 0x02 #define DRM_NOUVEAU_MEM_ALLOC 0x03 #define DRM_NOUVEAU_MEM_FREE 0x04 #define DRM_NOUVEAU_GETPARAM 0x05 -- cgit v1.2.3 From 694e1c5c3f768436651ddf95e11ab5a89ccc8ffa Mon Sep 17 00:00:00 2001 From: Arthur Huillet Date: Wed, 11 Jul 2007 02:35:10 +0200 Subject: Added support for PCIGART for PCI(E) cards.
