From b9335b9a01fc5eadeec6c50a81e68a9e9799de2d Mon Sep 17 00:00:00 2001 From: Thomas Zimmermann Date: Wed, 23 Sep 2020 12:21:51 +0200 Subject: [PATCH] drm/rockchip: Convert to drm_gem_object_funcs MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit GEM object functions deprecate several similar callback interfaces in struct drm_driver. This patch replaces the per-driver callbacks with per-instance callbacks in rockchip. The only exception is gem_prime_mmap, which is non-trivial to convert. v3: * update documentation Signed-off-by: Thomas Zimmermann Reviewed-by: Daniel Vetter Acked-by: Christian König Link: https://patchwork.freedesktop.org/patch/msgid/20200923102159.24084-15-tzimmermann@suse.de (cherry picked from commit 0d590af3140d0f84c537a9ad252aecc780ed7aa5) --- drivers/gpu/drm/rockchip/rockchip_drm_drv.c | 5 ----- drivers/gpu/drm/rockchip/rockchip_drm_gem.c | 12 +++++++++++- 2 files changed, 11 insertions(+), 6 deletions(-) diff --git a/drivers/gpu/drm/rockchip/rockchip_drm_drv.c b/drivers/gpu/drm/rockchip/rockchip_drm_drv.c index 0f3eb392fe39..b7654f5e4225 100644 --- a/drivers/gpu/drm/rockchip/rockchip_drm_drv.c +++ b/drivers/gpu/drm/rockchip/rockchip_drm_drv.c @@ -212,15 +212,10 @@ static const struct file_operations rockchip_drm_driver_fops = { static struct drm_driver rockchip_drm_driver = { .driver_features = DRIVER_MODESET | DRIVER_GEM | DRIVER_ATOMIC, .lastclose = drm_fb_helper_lastclose, - .gem_vm_ops = &drm_gem_cma_vm_ops, - .gem_free_object_unlocked = rockchip_gem_free_object, .dumb_create = rockchip_gem_dumb_create, .prime_handle_to_fd = drm_gem_prime_handle_to_fd, .prime_fd_to_handle = drm_gem_prime_fd_to_handle, - .gem_prime_get_sg_table = rockchip_gem_prime_get_sg_table, .gem_prime_import_sg_table = rockchip_gem_prime_import_sg_table, - .gem_prime_vmap = rockchip_gem_prime_vmap, - .gem_prime_vunmap = rockchip_gem_prime_vunmap, .gem_prime_mmap = rockchip_gem_mmap_buf, .fops = &rockchip_drm_driver_fops, .name = DRIVER_NAME, diff --git a/drivers/gpu/drm/rockchip/rockchip_drm_gem.c b/drivers/gpu/drm/rockchip/rockchip_drm_gem.c index 62e5d0970525..1cf4631461c9 100644 --- a/drivers/gpu/drm/rockchip/rockchip_drm_gem.c +++ b/drivers/gpu/drm/rockchip/rockchip_drm_gem.c @@ -295,6 +295,14 @@ static void rockchip_gem_release_object(struct rockchip_gem_object *rk_obj) kfree(rk_obj); } +static const struct drm_gem_object_funcs rockchip_gem_object_funcs = { + .free = rockchip_gem_free_object, + .get_sg_table = rockchip_gem_prime_get_sg_table, + .vmap = rockchip_gem_prime_vmap, + .vunmap = rockchip_gem_prime_vunmap, + .vm_ops = &drm_gem_cma_vm_ops, +}; + static struct rockchip_gem_object * rockchip_gem_alloc_object(struct drm_device *drm, unsigned int size) { @@ -309,6 +317,8 @@ static struct rockchip_gem_object * obj = &rk_obj->base; + obj->funcs = &rockchip_gem_object_funcs; + drm_gem_object_init(drm, obj, size); return rk_obj; @@ -337,7 +347,7 @@ rockchip_gem_create_object(struct drm_device *drm, unsigned int size, } /* - * rockchip_gem_free_object - (struct drm_driver)->gem_free_object_unlocked + * rockchip_gem_free_object - (struct drm_gem_object_funcs)->free * callback function */ void rockchip_gem_free_object(struct drm_gem_object *obj) From ba7e8c9f9c79119c569466b08b58a3b20aa0dca9 Mon Sep 17 00:00:00 2001 From: Thomas Zimmermann Date: Mon, 28 Sep 2020 10:16:43 +0200 Subject: [PATCH] drm/rockchip: Include for drm_gem_cm_vm_ops MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Include to get drm_gem_cma_vm_ops.
