(brian) * 1.8 - Remove need to call cleanup ioctls on last client exit (keith) * Add 'GET' queries for starting additional clients on different VT's. * 1.9 - Add DRM_IOCTL_RADEON_CP_RESUME ioctl. * Add texture rectangle support for r100. * 1.10- Add SETPARAM ioctl; first parameter to set is FB_LOCATION, which * clients use to tell the DRM where they think the framebuffer is * located in the card's address space * 1.11- Add packet R200_EMIT_RB3D_BLENDCOLOR to support GL_EXT_blend_color * and GL_EXT_blend_[func|equation]_separate on r200 */ static drm_ioctl_desc_t ioctls[] = { [DRM_IOCTL_NR(DRM_RADEON_CP_INIT)] = {radeon_cp_init, 1, 1}, [DRM_IOCTL_NR(DRM_RADEON_CP_START)] = {radeon_cp_start, 1, 1}, [DRM_IOCTL_NR(DRM_RADEON_CP_STOP)] = {radeon_cp_stop, 1, 1}, [DRM_IOCTL_NR(DRM_RADEON_CP_RESET)] = {radeon_cp_reset, 1, 1}, [DRM_IOCTL_NR(DRM_RADEON_CP_IDLE)] = {radeon_cp_idle, 1, 0}, [DRM_IOCTL_NR(DRM_RADEON_CP_RESUME)] = {radeon_cp_resume, 1, 0}, [DRM_IOCTL_NR(DRM_RADEON_RESET)] = {radeon_engine_reset, 1, 0}, [DRM_IOCTL_NR(DRM_RADEON_FULLSCREEN)] = {radeon_fullscreen, 1, 0}, [DRM_IOCTL_NR(DRM_RADEON_SWAP)] = {radeon_cp_swap, 1, 0}, [DRM_IOCTL_NR(DRM_RADEON_CLEAR)] = {radeon_cp_clear, 1, 0}, [DRM_IOCTL_NR(DRM_RADEON_VERTEX)] = {radeon_cp_vertex, 1, 0}, [DRM_IOCTL_NR(DRM_RADEON_INDICES)] = {radeon_cp_indices, 1, 0}, [DRM_IOCTL_NR(DRM_RADEON_TEXTURE)] = {radeon_cp_texture, 1, 0}, [DRM_IOCTL_NR(DRM_RADEON_STIPPLE)] = {radeon_cp_stipple, 1, 0}, [DRM_IOCTL_NR(DRM_RADEON_INDIRECT)] = {radeon_cp_indirect, 1, 1}, [DRM_IOCTL_NR(DRM_RADEON_VERTEX2)] = {radeon_cp_vertex2, 1, 0}, [DRM_IOCTL_NR(DRM_RADEON_CMDBUF)] = {radeon_cp_cmdbuf, 1, 0}, [DRM_IOCTL_NR(DRM_RADEON_GETPARAM)] = {radeon_cp_getparam, 1, 0}, [DRM_IOCTL_NR(DRM_RADEON_FLIP)] = {radeon_cp_flip, 1, 0}, [DRM_IOCTL_NR(DRM_RADEON_ALLOC)] = {radeon_mem_alloc, 1, 0}, [DRM_IOCTL_NR(DRM_RADEON_FREE)] = {radeon_mem_free, 1, 0}, [DRM_IOCTL_NR(DRM_RADEON_INIT_HEAP)] = {radeon_mem_init_heap, 1, 1}, [DRM_IOCTL_NR(DRM_RADEON_IRQ_EMIT)] = {radeon_irq_emit, 1, 0}, [DRM_IOCTL_NR(DRM_RADEON_IRQ_WAIT)] = {radeon_irq_wait, 1, 0}, [DRM_IOCTL_NR(DRM_RADEON_SETPARAM)] = {radeon_cp_setparam, 1, 0}, }; static struct drm_driver_fn driver_fn = { .driver_features = DRIVER_USE_AGP | DRIVER_USE_MTRR | DRIVER_PCI_DMA | DRIVER_SG | DRIVER_HAVE_IRQ | DRIVER_HAVE_DMA | DRIVER_IRQ_SHARED | DRIVER_IRQ_VBL, .dev_priv_size = sizeof(drm_radeon_buf_priv_t), .preinit = radeon_preinit, .postinit = radeon_postinit, .postcleanup = radeon_postcleanup, .prerelease = radeon_driver_prerelease, .pretakedown = radeon_driver_pretakedown, .open_helper = radeon_driver_open_helper, .vblank_wait = radeon_driver_vblank_wait, .irq_preinstall = radeon_driver_irq_preinstall, .irq_postinstall = radeon_driver_irq_postinstall, .irq_uninstall = radeon_driver_irq_uninstall, .irq_handler = radeon_driver_irq_handler, .free_filp_priv = radeon_driver_free_filp_priv, .reclaim_buffers = drm_core_reclaim_buffers, .get_map_ofs = drm_core_get_map_ofs, .get_reg_ofs = drm_core_get_reg_ofs, .postinit = postinit, .version = version, .ioctls = ioctls, .num_ioctls = DRM_ARRAY_SIZE(ioctls), .dma_ioctl = radeon_cp_buffers, .fops = { .owner = THIS_MODULE, .open = drm_open, .release = drm_release, .ioctl = drm_ioctl, .mmap = drm_mmap, .fasync = drm_fasync, } , }; static int probe(struct pci_dev *pdev, const struct pci_device_id *ent) { return drm_probe(pdev, ent, &driver_fn); } static struct pci_driver driver = { .name = DRIVER_NAME, .id_table = pciidlist, .probe = probe, .remove = __devexit_p(drm_cleanup_pci), }; static int __init radeon_init(void) { return drm_init(&driver, pciidlist, &driver_fn); } static void __exit radeon_exit(void) { drm_exit(&driver); } module_init(radeon_init); module_exit(radeon_exit); MODULE_AUTHOR(DRIVER_AUTHOR); MODULE_DESCRIPTION(DRIVER_DESC); MODULE_LICENSE("GPL and additional rights");
