From fabc64dd573f01a2160be474b4abc65a3a9aa5ea Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Fri, 29 Aug 2003 19:24:36 +0000 Subject: Port the SiS DRM to FreeBSD. This includes the ability for the DRM to allocate framebuffer memory without sisfb, and a new ioctl to be used by the X Server which tells the DRM what region of framebuffer memory to allocate from. Also fixes a possibility to panic the kernel I believe. Tested on linux with sisfb and FreeBSD (without sisfb) with new DRI only. --- shared-core/sis_drm.h | 33 +++++++++++++++++++++++++++++++++ 1 file changed, 33 insertions(+) create mode 100644 shared-core/sis_drm.h (limited to 'shared-core/sis_drm.h') diff --git a/shared-core/sis_drm.h b/shared-core/sis_drm.h new file mode 100644 index 00000000..49505719 --- /dev/null +++ b/shared-core/sis_drm.h @@ -0,0 +1,33 @@ + +#ifndef __SIS_DRM_H__ +#define __SIS_DRM_H__ + +/* SiS specific ioctls */ +#define DRM_IOCTL_SIS_FB_ALLOC DRM_IOWR(0x44, drm_sis_mem_t) +#define DRM_IOCTL_SIS_FB_FREE DRM_IOW( 0x45, drm_sis_mem_t) +#define DRM_IOCTL_SIS_AGP_INIT DRM_IOWR(0x53, drm_sis_agp_t) +#define DRM_IOCTL_SIS_AGP_ALLOC DRM_IOWR(0x54, drm_sis_mem_t) +#define DRM_IOCTL_SIS_AGP_FREE DRM_IOW( 0x55, drm_sis_mem_t) +#define DRM_IOCTL_SIS_FB_INIT DRM_IOW( 0x56, drm_sis_fb_t) +/* +#define DRM_IOCTL_SIS_FLIP DRM_IOW( 0x48, drm_sis_flip_t) +#define DRM_IOCTL_SIS_FLIP_INIT DRM_IO( 0x49) +#define DRM_IOCTL_SIS_FLIP_FINAL DRM_IO( 0x50) +*/ + +typedef struct { + int context; + unsigned int offset; + unsigned int size; + unsigned long free; +} drm_sis_mem_t; + +typedef struct { + unsigned int offset, size; +} drm_sis_agp_t; + +typedef struct { + unsigned int offset, size; +} drm_sis_fb_t; + +#endif /* __SIS_DRM_H__ */ -- cgit v1.2.3
