From 49a3f51dfeeecb52c5aa28c5cb9592fe5e39bf95 Mon Sep 17 00:00:00 2001 From: Thomas Zimmermann Date: Tue, 3 Nov 2020 10:30:11 +0100 Subject: drm/gem: Use struct dma_buf_map in GEM vmap ops and convert GEM backends MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This patch replaces the vmap/vunmap's use of raw pointers in GEM object functions with instances of struct dma_buf_map. GEM backends are converted as well. For most of them, this simply changes the returned type. TTM-based drivers now return information about the location of the memory, either system or I/O memory. GEM VRAM helpers and qxl now use ttm_bo_vmap() et al. Amdgpu, nouveau and radeon use drm_gem_ttm_vmap() et al instead of implementing their own vmap callbacks. v7: * init QXL cursor to mapped BO buffer (kernel test robot) v5: * update vkms after switch to shmem v4: * use ttm_bo_vmap(), drm_gem_ttm_vmap(), et al. (Daniel, Christian) * fix a trailing { in drm_gem_vmap() * remove several empty functions instead of converting them (Daniel) * comment uses of raw pointers with a TODO (Daniel) * TODO list: convert more helpers to use struct dma_buf_map Signed-off-by: Thomas Zimmermann Acked-by: Christian König Tested-by: Sam Ravnborg Link: https://patchwork.freedesktop.org/patch/msgid/20201103093015.1063-7-tzimmermann@suse.de --- drivers/gpu/drm/qxl/qxl_drv.h | 11 +++++++---- 1 file changed, 7 insertions(+), 4 deletions(-) (limited to 'drivers/gpu/drm/qxl/qxl_drv.h') diff --git a/drivers/gpu/drm/qxl/qxl_drv.h b/drivers/gpu/drm/qxl/qxl_drv.h index 3602e8b34189..eb437fea5d9e 100644 --- a/drivers/gpu/drm/qxl/qxl_drv.h +++ b/drivers/gpu/drm/qxl/qxl_drv.h @@ -30,6 +30,7 @@ * Definitions taken from spice-protocol, plus kernel driver specific bits. */ +#include #include #include #include @@ -50,6 +51,8 @@ #include "qxl_dev.h" +struct dma_buf_map; + #define DRIVER_AUTHOR "Dave Airlie" #define DRIVER_NAME "qxl" @@ -79,7 +82,7 @@ struct qxl_bo { /* Protected by tbo.reserved */ struct ttm_place placements[3]; struct ttm_placement placement; - struct ttm_bo_kmap_obj kmap; + struct dma_buf_map map; void *kptr; unsigned int map_count; int type; @@ -335,7 +338,6 @@ int qxl_gem_object_open(struct drm_gem_object *obj, struct drm_file *file_priv); void qxl_gem_object_close(struct drm_gem_object *obj, struct drm_file *file_priv); void qxl_bo_force_delete(struct qxl_device *qdev); -int qxl_bo_kmap(struct qxl_bo *bo, void **ptr); /* qxl_dumb.c */ int qxl_mode_dumb_create(struct drm_file *file_priv, @@ -445,8 +447,9 @@ struct sg_table *qxl_gem_prime_get_sg_table(struct drm_gem_object *obj); struct drm_gem_object *qxl_gem_prime_import_sg_table( struct drm_device *dev, struct dma_buf_attachment *attach, struct sg_table *sgt); -void *qxl_gem_prime_vmap(struct drm_gem_object *obj); -void qxl_gem_prime_vunmap(struct drm_gem_object *obj, void *vaddr); +int qxl_gem_prime_vmap(struct drm_gem_object *obj, struct dma_buf_map *map); +void qxl_gem_prime_vunmap(struct drm_gem_object *obj, + struct dma_buf_map *map); int qxl_gem_prime_mmap(struct drm_gem_object *obj, struct vm_area_struct *vma); -- cgit v1.2.3
