This is just my initial interface pass, because mostly everything else can be cleaned up in tree, the ABI not so much. Dave. Dave.

Attempting to sync my userland header in xorg with what is used in the kernel. Since we have BSD users I attempted to play nice. This weekend I played with a new header format that should satisfy everyone. > Also I don't think its really necessary to add all the pci ids there, > just put them in the driver. Would you be okay with the pci ids being in via_drm.h instead? I have to look but if I remember correctly some of those pci ids are for the north bridge bus which is used to detect how much VRAM we have. > > > > #define DRM_IOCTL_VIA_ALLOCMEM DRM_IOWR(DRM_COMMAND_BASE + DRM_VIA_ALLOCMEM, drm_via_mem_t) > > #define DRM_IOCTL_VIA_FREEMEM DRM_IOW( DRM_COMMAND_BASE + DRM_VIA_FREEMEM, drm_via_mem_t) > > @@ -86,6 +89,7 @@ > > #define DRM_IOCTL_VIA_FB_INIT DRM_IOWR(DRM_COMMAND_BASE + DRM_VIA_FB_INIT, drm_via_fb_t) > > #define DRM_IOCTL_VIA_MAP_INIT DRM_IOWR(DRM_COMMAND_BASE + DRM_VIA_MAP_INIT, drm_via_init_t) > > #define DRM_IOCTL_VIA_DEC_FUTEX DRM_IOW( DRM_COMMAND_BASE + DRM_VIA_DEC_FUTEX, drm_via_futex_t) > > +#define DRM_IOCTL_VIA_OLD_GEM_CREATE DRM_IOWR(DRM_COMMAND_BASE + DRM_VIA_OLD_GEM_CREATE, struct drm_via_gem_create) > > #define DRM_IOCTL_VIA_DMA_INIT DRM_IOWR(DRM_COMMAND_BASE + DRM_VIA_DMA_INIT, drm_via_dma_init_t) > > #define DRM_IOCTL_VIA_CMDBUFFER DRM_IOW( DRM_COMMAND_BASE + DRM_VIA_CMDBUFFER, drm_via_cmdbuffer_t) > > #define DRM_IOCTL_VIA_FLUSH DRM_IO( DRM_COMMAND_BASE + DRM_VIA_FLUSH) > > @@ -96,6 +100,13 @@ > > #define DRM_IOCTL_VIA_DMA_BLIT DRM_IOW(DRM_COMMAND_BASE + DRM_VIA_DMA_BLIT, drm_via_dmablit_t) > > #define DRM_IOCTL_VIA_BLIT_SYNC DRM_IOW(DRM_COMMAND_BASE + DRM_VIA_BLIT_SYNC, drm_via_blitsync_t) > > > > +/* KMS ioctls */ > > +#define DRM_IOCTL_VIA_GETPARAM DRM_IOR(DRM_COMMAND_BASE + DRM_VIA_GETPARAM, struct drm_via_param) > > +#define DRM_IOCTL_VIA_SETPARAM DRM_IOW(DRM_COMMAND_BASE + DRM_VIA_SETPARAM, struct drm_via_param) > > +#define DRM_IOCTL_VIA_GEM_CREATE DRM_IOWR(DRM_COMMAND_BASE + DRM_VIA_GEM_CREATE, struct drm_via_gem_create) > > +#define DRM_IOCTL_VIA_GEM_WAIT DRM_IOW(DRM_COMMAND_BASE + DRM_VIA_GEM_WAIT, struct drm_via_gem_wait) > > +#define DRM_IOCTL_VIA_GEM_STATE DRM_IOWR(DRM_COMMAND_BASE + DRM_VIA_GEM_STATE, struct drm_via_gem_create) > > why does gem_state take a gem_create struct? is it the same info it returns?
