From 06d6620164b2989468cd4ea809645e6483623314 Mon Sep 17 00:00:00 2001 From: Thomas Zimmermann Date: Fri, 5 Jun 2020 09:32:06 +0200 Subject: [PATCH] drm/cma-helper: Rework DRM_GEM_CMA_VMAP_DRIVER_OPS macro Rename the macro to DRM_GEM_CMA_DRIVER_OPS_VMAP to align naming with SHMEM helpers and drm_gem_cma_prime_import_sg_table_vmap(). An variant of the macro is provided for drivers that override the default .dumb_create callback. Adapt drivers to the changes. v3: * rename macro to signal implicit vmap on imported buffers v2: * provide DRM_GEM_CMA_DRIVER_OPS_WITH_DUMB_CREATE Signed-off-by: Thomas Zimmermann Reviewed-by: Sam Ravnborg Reviewed-by: Laurent Pinchart Reviewed-by: Emil Velikov Link: https://patchwork.freedesktop.org/patch/msgid/20200605073247.4057-3-tzimmermann@suse.de --- drivers/gpu/drm/drm_gem_cma_helper.c | 2 +- drivers/gpu/drm/sun4i/sun4i_drv.c | 3 +-- drivers/gpu/drm/tidss/tidss_drv.c | 2 +- drivers/gpu/drm/tiny/hx8357d.c | 2 +- drivers/gpu/drm/tiny/ili9225.c | 2 +- drivers/gpu/drm/tiny/ili9341.c | 2 +- drivers/gpu/drm/tiny/ili9486.c | 2 +- drivers/gpu/drm/tiny/mi0283qt.c | 2 +- drivers/gpu/drm/tiny/repaper.c | 2 +- drivers/gpu/drm/tiny/st7586.c | 2 +- drivers/gpu/drm/tiny/st7735r.c | 2 +- include/drm/drm_gem_cma_helper.h | 30 ++++++++++++++++++++++++++---- 12 files changed, 37 insertions(+), 16 deletions(-) diff --git a/drivers/gpu/drm/drm_gem_cma_helper.c b/drivers/gpu/drm/drm_gem_cma_helper.c index 842e2fa..06a5b9e 100644 --- a/drivers/gpu/drm/drm_gem_cma_helper.c +++ b/drivers/gpu/drm/drm_gem_cma_helper.c @@ -620,7 +620,7 @@ EXPORT_SYMBOL(drm_gem_cma_create_object_default_funcs); * address set.
