Currently the rotator unit is used to copy decoded frames out into buffers provided by videobuf2. Since the CODA reports the I/P/B frame type of the last decoded frame, and this frame will be copied out in a later device_run, depending on display order, we have to store the frame type until such time. This patch also adds the B-frame type. Signed-off-by:

fc906b6d "Remove special clock usage in driver" removed initialization of MFC special clock, arguing that there's no need to do it explicitly, since it's one of MFC gate clock's dependencies and gets enabled along with it. However, there's no promise of keeping this hierarchy across Exynos SoC releases, therefore this approach fails to provide a stable, portable solution. Out of all MFC versions, only v6 doesn't use special clock at all. For other versions log a message only in case clk_get fails, as not all the devices with the same MFC version require initializing the clock explicitly. Signed-off-by:

In the s5p_mfc_alloc_firmware() function there are some mistakes where the code checks whether the DMA memory is properly allocated or not. First of all dma_alloc_coherent() returns NULL in case of error. The code also checked two times fw_virt_addr, ignoring the bank2_virt pointer. Signed-off-by:

This patch removes the null test on dvb. dvb is initialized at the beginning of the function to &port->dvb. Since port is dereferenced prior to the null test, port must be a valid pointer, and &port->dvb cannot be null. The following Coccinelle script is used for detecting the change: @r@ expression e,f; identifier g,y; statement S1,S2; @@ *e = &f->g <+... f->y ...+> *if (e != NULL || ...) S1 else S2 Signed-off-by:

The issue was discovered by static analysis. It turns out that code is somewhat insane, being if (x) {...} else { if (x) {...} } Edited it to do the only reasonable thing, which is to log the information about the failed call. The most descriptive logging commands set is taken from original code. Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=79801Reported-by:David Binderman <dcb314@hotmail.com> Signed-off-by:

If the vidioc_cropcap op is implemented by the driver then the v4l2 core will call that directly. If g_selection is available, then the core cropcap implementation uses g_selection to fill in the bounds and defrect and it sets the pixelaspect to 1x1. But if both are available, then I would like to use g_selection to fill in defrect and bounds before calling cropcap. That way the driver's cropcap implementation doesn't have to set defrect or bounds. Signed-off-by:

The other format ioctls (g/s/try_fmt) all check if the passed buffer type makes sense for the device node's vfl_type. E.g. it makes no sense for a VBI buffer type to be passed through a video node instead of a vbi node. But this check was missing in ENUM_FMT which can cause a problem if you have both video and sdr device nodes. Signed-off-by:

The OMAP4 camera support depends on I2C and VIDEO_V4L2, both of which can be loadable modules. This causes build failures if we want the camera driver to be built-in. This can be solved by turning the option into "tristate", which unfortunately causes another problem, because the driver incorrectly calls a platform-internal interface for omap4_ctrl_pad_readl/omap4_ctrl_pad_writel. Instead, this patch just forbids the invalid configurations and ensures that the driver can only be built if all its dependencies are built-in. Cc: stable@vger.kernel.org Signed-off-by:

When a fatal error occurs that render the device unusable, the only options for a driver to signal the error condition to userspace is to set the V4L2_BUF_FLAG_ERROR flag when dequeuing buffers and to return an error from the buffer prepare handler when queuing buffers. The buffer error flag indicates a transient error and can't be used by applications to detect fatal errors. Returning an error from vb2_qbuf() is thus the only real indication that a fatal error occurred. However, this is difficult to handle for multithreaded applications that requeue buffers from a thread other than the control thread. In particular the poll() call in the control thread will not notify userspace of the error. This patch adds an explicit mechanism to report fatal errors to userspace. Drivers can call the vb2_queue_error() function to signal a fatal error. From this moment on, buffer preparation will return -EIO to userspace, and vb2_poll() will set the POLLERR flag and return immediately. The error flag is cleared when cancelling the queue, either at stream off time (through vb2_streamoff) or when releasing the queue with vb2_queue_release(). Signed-off-by:

The V4L2 specification states that "When the application did not call VIDIOC_QBUF or VIDIOC_STREAMON yet the poll() function succeeds, but sets the POLLERR flag in the revents field." The vb2_poll() function sets POLLERR when the queued buffers list is empty, regardless of whether this is caused by the stream not being active yet, or by a transient buffer underrun. Bring the implementation in line with the specification by returning POLLERR if no buffer has been queued only when the queue is not streaming. Buffer underruns during streaming are not treated specially anymore and just result in poll() blocking until the next event. Signed-off-by:

Pixel color components can be scaled using either bilinear interpolation or a multitap filter. The multitap filter provides better results, but can't be selected when the alpha layer need to be scaled down by more than 1/2. Disable alpha scaling when the input has a fixed alpha value, and program the UDS to output a fixed alpha value in that case. This ensures the multitap filter will be used whenever possible.
