This patch replaces the per-driver callbacks with per-instance callbacks in xen. The only exception is gem_prime_mmap, which is non-trivial to convert. v2: * convert xen_drm_drv_free_object_unlocked() to static callback (Oleksandr) Signed-off-by: Thomas Zimmermann Acked-by: Oleksandr Andrushchenko --- drivers/gpu/drm/xen/xen_drm_front.c | 44 ++++++++++--------------- drivers/gpu/drm/xen/xen_drm_front.h | 2 ++ drivers/gpu/drm/xen/xen_drm_front_gem.c | 15 +++++++++ 3 files changed, 34 insertions(+), 27 deletions(-) diff --git a/drivers/gpu/drm/xen/xen_drm_front.c b/drivers/gpu/drm/xen/xen_drm_front.c index cc93a8c9547b..98b6d2ba088a 100644 --- a/drivers/gpu/drm/xen/xen_drm_front.c +++ b/drivers/gpu/drm/xen/xen_drm_front.c @@ -381,6 +381,23 @@ void xen_drm_front_on_frame_done(struct xen_drm_front_info *front_info, fb_cookie); } +void xen_drm_front_gem_object_free(struct drm_gem_object *obj) +{ + struct xen_drm_front_drm_info *drm_info = obj->dev->dev_private; + int idx; + + if (drm_dev_enter(obj->dev, &idx)) { + xen_drm_front_dbuf_destroy(drm_info->front_info, + xen_drm_front_dbuf_to_cookie(obj)); + drm_dev_exit(idx); + } else { + dbuf_free(&drm_info->front_info->dbuf_list, + xen_drm_front_dbuf_to_cookie(obj)); + } + + xen_drm_front_gem_free_object_unlocked(obj); +} + static int xen_drm_drv_dumb_create(struct drm_file *filp, struct drm_device *dev, struct drm_mode_create_dumb *args) @@ -435,23 +452,6 @@ static int xen_drm_drv_dumb_create(struct drm_file *filp, return ret; } -static void xen_drm_drv_free_object_unlocked(struct drm_gem_object *obj) -{ - struct xen_drm_front_drm_info *drm_info = obj->dev->dev_private; - int idx; - - if (drm_dev_enter(obj->dev, &idx)) { - xen_drm_front_dbuf_destroy(drm_info->front_info, - xen_drm_front_dbuf_to_cookie(obj)); - drm_dev_exit(idx); - } else { - dbuf_free(&drm_info->front_info->dbuf_list, - xen_drm_front_dbuf_to_cookie(obj)); - } - - xen_drm_front_gem_free_object_unlocked(obj); -} - static void xen_drm_drv_release(struct drm_device *dev) { struct xen_drm_front_drm_info *drm_info = dev->dev_private; @@ -483,22 +483,12 @@ static const struct file_operations xen_drm_dev_fops = { .mmap = xen_drm_front_gem_mmap, }; -static const struct vm_operations_struct xen_drm_drv_vm_ops = { - .open = drm_gem_vm_open, - .close = drm_gem_vm_close, -}; - static struct drm_driver xen_drm_driver = { .driver_features = DRIVER_GEM | DRIVER_MODESET | DRIVER_ATOMIC, .release = xen_drm_drv_release, - .gem_vm_ops = &xen_drm_drv_vm_ops, - .gem_free_object_unlocked = xen_drm_drv_free_object_unlocked, .prime_handle_to_fd = drm_gem_prime_handle_to_fd, .prime_fd_to_handle = drm_gem_prime_fd_to_handle, .gem_prime_import_sg_table = xen_drm_front_gem_import_sg_table, - .gem_prime_get_sg_table = xen_drm_front_gem_get_sg_table, - .gem_prime_vmap = xen_drm_front_gem_prime_vmap, - .gem_prime_vunmap = xen_drm_front_gem_prime_vunmap, .gem_prime_mmap = xen_drm_front_gem_prime_mmap, .dumb_create = xen_drm_drv_dumb_create, .fops = &xen_drm_dev_fops, diff --git a/drivers/gpu/drm/xen/xen_drm_front.h b/drivers/gpu/drm/xen/xen_drm_front.h index 54486d89650e..cefafe859aba 100644 --- a/drivers/gpu/drm/xen/xen_drm_front.h +++ b/drivers/gpu/drm/xen/xen_drm_front.h @@ -160,4 +160,6 @@ int xen_drm_front_page_flip(struct xen_drm_front_info *front_info, void xen_drm_front_on_frame_done(struct xen_drm_front_info *front_info, int conn_idx, u64 fb_cookie); +void xen_drm_front_gem_object_free(struct drm_gem_object *obj); + #endif /* __XEN_DRM_FRONT_H_ */ diff --git a/drivers/gpu/drm/xen/xen_drm_front_gem.c b/drivers/gpu/drm/xen/xen_drm_front_gem.c index a8aefaa38bd3..f3830a0d1808 100644 --- a/drivers/gpu/drm/xen/xen_drm_front_gem.c +++ b/drivers/gpu/drm/xen/xen_drm_front_gem.c @@ -57,6 +57,19 @@ static void gem_free_pages_array(struct xen_gem_object *xen_obj) xen_obj->pages = NULL; } +static const struct vm_operations_struct xen_drm_drv_vm_ops = { + .open = drm_gem_vm_open, + .close = drm_gem_vm_close, +}; + +static const struct drm_gem_object_funcs xen_drm_front_gem_object_funcs = { + .free = xen_drm_front_gem_object_free, + .get_sg_table = xen_drm_front_gem_get_sg_table, + .vmap = xen_drm_front_gem_prime_vmap, + .vunmap = xen_drm_front_gem_prime_vunmap, + .vm_ops = &xen_drm_drv_vm_ops, +}; + static struct xen_gem_object *gem_create_obj(struct drm_device *dev, size_t size) { @@ -67,6 +80,8 @@ static struct xen_gem_object *gem_create_obj(struct drm_device *dev, if (!xen_obj) return ERR_PTR(-ENOMEM); + xen_obj->base.funcs = &xen_drm_front_gem_object_funcs; + ret = drm_gem_object_init(dev, &xen_obj->base, size); if (ret < 0) { kfree(xen_obj);
