With CONFIG_V4L2=m and VIDEO_SAMSUNG_EXYNOS4_IS=y, we can select the individual drivers as built-in code when that should not be possible: drivers/built-in.o: In function `s5pcsis_set_fmt': policy.c:(.text+0x13afdc): undefined reference to `v4l_bound_align_image' drivers/built-in.o: In function `s5pcsis_probe': policy.c:(.text+0x13b440): undefined reference to `v4l2_of_parse_endpoint' policy.c:(.text+0x13b72c): undefined reference to `v4l2_subdev_init' Changing VIDEO_SAMSUNG_EXYNOS4_IS to tristate means that the dependency from CONFIG_V4L2 propates to the individual Kconfig symbols and they can only be built as loadable modules if V4L2 or any other of the dependencies itself is a module.

The build of m32r allmodconfig fails with the error: drivers/media/v4l2-core/videobuf2-dma-contig.c:484:2: error: implicit declaration of function 'dma_get_cache_alignment' The build of videobuf2-dma-contig.c depends on HAS_DMA and it is correctly mentioned in the Kconfig but the symbol VIDEO_STI_BDISP also selects VIDEOBUF2_DMA_CONTIG, so it is trying to compile videobuf2-dma-contig.c even though HAS_DMA is not defined.

In order to allow for automatic media device entities linking from the level of libv4l plugin the open system call shouldn't fail, as the libv4l plugins can begin their job not until it succeeds. This patch allows for leaving the pipeline not linked on open and postpones verifying it to the moment when streamon callback is called. Signed-off-by:

VIDIOC_SUBDEV_G_FMT ioctl should return TRY format previously set with VIDIOC_SUBDEV_S_FMT. Currently it is not the case as only ACTIVE formats are saved in the driver. Since the driver doesn't alter hardware state in the set_fmt op anyway, the op can save the format in both TRY and ACTIVE case. Signed-off-by:

Ironically, 7d4020c3 ("[media] exynos4-is: fix some warnings when compiling on arm64") fixed some format string bugs but introduced a new one. buf_index is a simple int, so it should be printed with %d, not %pad (which is correctly used for dma_addr_t).

The Media Control framework now requires entities to be registered with the media device before creating links so commit c7621b30 ("[media] v4l: vsp1: separate links creation from entities init") separated link creation from entities init. But unfortunately that patch introduced a regression since wrong links were created causing a boot failure on Renesas boards. This patch fixes the boot issue and also the media graph was compared by Geert Uytterhoeven to make sure that the driver changes required by the Media Control framework next generation did not affect the graph.

If we detect that there is nothing to do just set the flag and do not check if it was already set before. Races really do not matter. If the flag is set by any code then the shepherd will start dealing with the situation and reenable the vmstat workers when necessary again. Since commit 0eb77e98 ("vmstat: make vmstat_updater deferrable again and shut down on idle") quiet_vmstat might update cpu_stat_off and mark a particular cpu to be handled by vmstat_shepherd. This might trigger a VM_BUG_ON in vmstat_update because the work item might have been sleeping during the idle period and see the cpu_stat_off updated after the wake up. The VM_BUG_ON is therefore misleading and no more appropriate. Moreover it doesn't really suite any protection from real bugs because vmstat_shepherd will simply reschedule the vmstat_work anytime it sees a particular cpu set or vmstat_update would do the same from the worker context directly. Even when the two would race the result wouldn't be incorrect as the counters update is fully idempotent. Reported-by:
