From 4e7a8707cce75b4cdc046581ec0c1cc7c0c26e02 Mon Sep 17 00:00:00 2001 From: Simon Ser Date: Tue, 29 Jun 2021 17:08:32 +0200 Subject: buffer: add data_ptr access flags This allows callers to specify the operations they'll perform on the returned data pointer. The motivations for this are: - The upcoming Linux MAP_NOSIGBUS flag may only be usable on read-only mappings. - gbm_bo_map with GBM_BO_TRANSFER_READ hurts performance. --- include/wlr/types/wlr_buffer.h | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'include/wlr') diff --git a/include/wlr/types/wlr_buffer.h b/include/wlr/types/wlr_buffer.h index c714ddb6..6bf3c97b 100644 --- a/include/wlr/types/wlr_buffer.h +++ b/include/wlr/types/wlr_buffer.h @@ -30,8 +30,8 @@ struct wlr_buffer_impl { struct wlr_dmabuf_attributes *attribs); bool (*get_shm)(struct wlr_buffer *buffer, struct wlr_shm_attributes *attribs); - bool (*begin_data_ptr_access)(struct wlr_buffer *buffer, void **data, - uint32_t *format, size_t *stride); + bool (*begin_data_ptr_access)(struct wlr_buffer *buffer, uint32_t flags, + void **data, uint32_t *format, size_t *stride); void (*end_data_ptr_access)(struct wlr_buffer *buffer); }; -- cgit v1.2.3
