From e77c31ed60d1bbf4879b19309f848e0d8f6df504 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Fri, 23 Feb 2018 04:49:30 -0500 Subject: [PATCH] media: videobuf2: fix build issues with vb2-trace There was a trouble with vb2-trace: instead of being part of VB2 core, it was stored at V4L2 videodev. That was wrong, as it doesn't actually belong to V4L2 core. Now that vb2 is not part of v4l2-core, its trace functions should be moved altogether. So, move it to its rightful place: at videobuf2-core. That fixes those errors: drivers/media/common/videobuf2/videobuf2-core.o: In function `__read_once_size': ./include/linux/compiler.h:183: undefined reference to `__tracepoint_vb2_buf_queue' ./include/linux/compiler.h:183: undefined reference to `__tracepoint_vb2_buf_queue' ./include/linux/compiler.h:183: undefined reference to `__tracepoint_vb2_buf_done' ./include/linux/compiler.h:183: undefined reference to `__tracepoint_vb2_buf_done' ./include/linux/compiler.h:183: undefined reference to `__tracepoint_vb2_qbuf' ./include/linux/compiler.h:183: undefined reference to `__tracepoint_vb2_qbuf' ./include/linux/compiler.h:183: undefined reference to `__tracepoint_vb2_dqbuf' ./include/linux/compiler.h:183: undefined reference to `__tracepoint_vb2_dqbuf' drivers/media/common/videobuf2/videobuf2-core.o:(__jump_table+0x10): undefined reference to `__tracepoint_vb2_buf_queue' drivers/media/common/videobuf2/videobuf2-core.o:(__jump_table+0x28): undefined reference to `__tracepoint_vb2_buf_done' drivers/media/common/videobuf2/videobuf2-core.o:(__jump_table+0x40): undefined reference to `__tracepoint_vb2_qbuf' drivers/media/common/videobuf2/videobuf2-core.o:(__jump_table+0x58): undefined reference to `__tracepoint_vb2_dqbuf' Reported-by: kbuild test robot Signed-off-by: Mauro Carvalho Chehab --- drivers/media/common/videobuf2/Makefile | 3 +++ drivers/media/{v4l2-core => common/videobuf2}/vb2-trace.c | 0 drivers/media/v4l2-core/Makefile | 3 +-- 3 files changed, 4 insertions(+), 2 deletions(-) rename drivers/media/{v4l2-core => common/videobuf2}/vb2-trace.c (100%) diff --git a/drivers/media/common/videobuf2/Makefile b/drivers/media/common/videobuf2/Makefile index 7e27bdd44dcc..067badb1aaa7 100644 --- a/drivers/media/common/videobuf2/Makefile +++ b/drivers/media/common/videobuf2/Makefile @@ -6,3 +6,6 @@ obj-$(CONFIG_VIDEOBUF2_VMALLOC) += videobuf2-vmalloc.o obj-$(CONFIG_VIDEOBUF2_DMA_CONTIG) += videobuf2-dma-contig.o obj-$(CONFIG_VIDEOBUF2_DMA_SG) += videobuf2-dma-sg.o obj-$(CONFIG_VIDEOBUF2_DVB) += videobuf2-dvb.o +ifeq ($(CONFIG_TRACEPOINTS),y) + obj-$(CONFIG_VIDEOBUF2_CORE) += vb2-trace.o +endif diff --git a/drivers/media/v4l2-core/vb2-trace.c b/drivers/media/common/videobuf2/vb2-trace.c similarity index 100% rename from drivers/media/v4l2-core/vb2-trace.c rename to drivers/media/common/videobuf2/vb2-trace.c diff --git a/drivers/media/v4l2-core/Makefile b/drivers/media/v4l2-core/Makefile index 80de2cb9c476..7df54582e956 100644 --- a/drivers/media/v4l2-core/Makefile +++ b/drivers/media/v4l2-core/Makefile @@ -13,7 +13,7 @@ ifeq ($(CONFIG_COMPAT),y) endif obj-$(CONFIG_V4L2_FWNODE) += v4l2-fwnode.o ifeq ($(CONFIG_TRACEPOINTS),y) - videodev-objs += vb2-trace.o v4l2-trace.o + videodev-objs += v4l2-trace.o endif videodev-$(CONFIG_MEDIA_CONTROLLER) += v4l2-mc.o @@ -35,4 +35,3 @@ obj-$(CONFIG_VIDEOBUF_DVB) += videobuf-dvb.o ccflags-y += -I$(srctree)/drivers/media/dvb-frontends ccflags-y += -I$(srctree)/drivers/media/tuners -
