changeset 70433a15 ("media: videobuf2: Refactor vb2_fileio_data and vb2_thread") broke videobuf2-dvb. The root cause is that, instead of calling threadio->fnc() for all types of events except for VB2_BUF_STATE_ERROR, it was calling it only for VB2_BUF_STATE_DONE. With that, the DVB thread were never called. Cc: stable@vger.kernel.org # Kernel >= 4.3 Signed-off-by:

The vb2_thread implementation was made generic and was moved from videobuf2-v4l2.c to videobuf2-core.c in commit af3bac1a. Unfortunately that clearly was never tested since it broke read() causing NULL address references. The root cause was confused handling of vb2_buffer vs v4l2_buffer (the pb pointer in various core functions). The v4l2_buffer no longer exists after moving the code into the core and it is no longer needed. However, the vb2_thread code passed a pointer to a vb2_buffer to the core functions were a v4l2_buffer pointer was expected and vb2_thread expected that the vb2_buffer fields would be filled in correctly. This is obviously wrong since v4l2_buffer != vb2_buffer. Note that the pb pointer is a void pointer, so no type-checking took place. This patch fixes this problem: 1) allow pb to be NULL for vb2_core_(d)qbuf. The vb2_thread code will use a NULL pointer here since they don't care about v4l2_buffer anyway. 2) let vb2_core_dqbuf pass back the index of the received buffer. This is all vb2_thread needs: this index is the index into the q->bufs array and vb2_thread just gets the vb2_buffer from there. 3) the fileio->b pointer (that originally contained a v4l2_buffer) is removed altogether since it is no longer needed. Tested with vivid and the cobalt driver. Cc: stable@vger.kernel.org # Kernel >= 4.3 Signed-off-by:

The tda1004x was updating the properties cache before locking. If the device is not locked, the data at the registers are just random values with no real meaning. This caused the driver to fail with libdvbv5, as such library calls GET_PROPERTY from time to time, in order to return the DVB stats.

This is a partial revert of commit ed8d1cf0 ("[media] Export I2C module alias information in missing drivers") that exported the module aliases for the I2C drivers that were missing to make autoload to work. But there is a bug report [0] that auto load of the ir-kbd-i2c driver cause the Hauppauge HD-PVR driver to not behave correctly. This is a hdpvr latent bug that was just exposed by ir-kbd-i2c module autoloading working and will also happen if the I2C driver is built-in or a user calls modprobe to load the module and register the driver. But there is a regression experimented by users so until the real bug is fixed, let's not export the module alias for the ir-kbd-i2c driver even when this just masks the actual issue.

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.

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:

Add dummy.o to the targets list, and fill targets automatically from $(vmlinuzobjs) to avoid having to maintain two lists. When building with XZ compression copy ashldi3.c to the build directory to use a different object file for the kernel and zboot. Without this the same object file need to be build with different flags which cause a rebuild at every run. Signed-off-by:

The extended flash address needs to be subtracted from bcm_tag flash image offsets. Move this value to the bcm_tag header file. Renamed define name to consistently use bcm963xx for flash layout which should be considered a property of the board and not the SoC (i.e. bcm63xx could theoretically be used on a board without CFE or any flash).

The header arch/mips/kvm/opcode.h defines a few extra opcodes which aren't in arch/mips/include/uapi/asm/inst.h. There's nothing KVM specific about them, so lets move them into inst.h where they belong and delete the header. Note that mfmcz_op is renamed to mfmc0_op to match the instruction set manual, and wait_op was already added to inst.h in commit b0a3eae2 ("MIPS: inst.h: define COP0 wait op"), merged in v3.16-rc1.
