When stop_streaming is called we need to cleanup the queued vb2 buffers properly. This was not previously being done which caused kernel warning when the application using the resources was killed. Kernel warnings were also generated on successful completion of a de-interlacing case as well as upon aborting a conversion. Make sure every vb2 buffers is properly handled in all cases.

Current scaler library implementation of sc_set_hs_coeffs and sc_set_vs_coeffs tries to return immediately if the calculated coefficient index is already being used. As the same scaler block is going to be used for all the VPE contexts, even if the calculated index is same, the parameters have to be reconfigured for each of the context. Because of this, when multiple contexts use the same coefficients, all other contexts would have zero scaling coefficients. Fix this and also remove the unnecessary hs_index and vs_index fields.

VPDMA block used in ti-vip and ti-vpe modules have support for up to 8 hardware descriptor lists. A descriptor list can be submitted to any of the 8 lists (as long as it's not busy). When multiple clients want to transfer data in parallel, its easier to allocate one list per client and let it use it. This way, the list numbers need not be hard-coded into the driver.

vpe_irq checks for the possible interrupt sources and prints the errors for the DEI_ERROR and DS_UV interrupts. But it also post the next descriptor list irrespective of whichever interrupt has occurred. Because of this, driver may release the buffers even before DMA is complete and also schedule next descriptor list. Fix this by _actually_ handling the IRQ only when ListComplete IRQ occurs.

For deinterlacing operation, each operation needs 2 fields in the history. This is achieved by holding three buffers in ctx->src_vbs[0,1,2] (f,f-1,f-2) This is achieved by using the ctx->sequence which gets reset via the s_fmt ioctl. These buffers are dequeued in stream OFF by calling free_vbs() But the corresponding references aren't removed anywhere. When application tries to stream ON and OFF continuously, s_fmt ioctl won't be called and it won't setup the srcdst parameters. Setting source/destination parameters in stream ON ioctl would make sure that the context is re-initialized before it is being used by the driver.

Current driver configures the line mode of the DEI clients from the open function directly. Even if the newly created context is not yet scheduled, it updates some of the VPDMA registers. This causes a problem in multi instance use case where just opening the m2m device second time causes the running job to stall. This happens especially if the source buffers used are NV12. While all other configuration is being written to context specific shadow registers, only line mode configuration is happening directly. As there is no shadow register for line mode configuration, it's better to separate the config_mode setting and line_mode setting. Call the new "set_line_modes" functions only when actually loading the mmrs. This makes sure that no non-running job will write to the registers directly.

Writing to the "VPDMA list attribute" register is considered as a list post. This informs the VPDMA firmware to load the list from the address which should be taken from the "VPDMA list address" register. As these two register writes are dependent, it is important that the two writes happen in atomic manner. This ensures multiple slices (which share same VPDMA) can post lists asynchronously and all of them point to the correct addresses. Slightly modified to implementation for the original patch to use spin_lock instead of mutex as the list post is also called from interrupt context.

Whenever VPDMA processes a data descriptor of a list, it processes it and sets up the channel for the DMA transaction. List manager holds the descriptor in the list until the DMA is complete. If sync_on_channel descriptor, or another descriptor for the same channel is present in the FIFO, list manager keeps them until the current channel is free. When the capture stream is closed suddenly while there are pending descriptors in the FIFO (streamON failed, application killed), it would keep the VPDMA in a busy state. Any further list post would fail with EBUSY. To avoid this, drivers need to stop the current processing list and cleanup all the resources VPDMA has taken and also clear the internal FSM of list manager. The state machine is cleared by issuing channel specific abort descriptor. Therefore, the vpdma_list_cleanup accepts an array of channels for which abort_channel descriptors should be posted. It is driver's responsibility to post for all the channels or the channels which were used in the last context.

The video source can generate the data in the SEQ_TB buffer format. In the case of TI SoC, the IVA_HD can generate the interlaced content in the SEQ_TB buffer format. This is the format where the top and bottom field data can be contained in a single buffer. For example, for NV12, interlaced format, the data in Y buffer will be arranged as Y-top followed by Y-bottom. And likewise for UV plane. Also, queuing one buffer of SEQ_TB is equivalent to queuing two different buffers for top and bottom fields. Driver needs to take care of this when handling source buffer lists.

Current VPE driver does not start the job until all the buffers for a transaction are queued. When running in multiple context, this might increase the processing latency. Alternate solution would be to try to continue the same context as long as buffers for the transaction are ready; else switch the context. This may increase number of context switches but it reduces latency significantly. In this approach, the job_ready always succeeds as long as there are buffers on the CAPTURE and OUTPUT stream. Processing may start immediately as the first 2 iterations don't need extra source buffers. Shift all the source buffers after each iteration and remove the oldest buffer. Also, with this removes the constraint of pre buffering 3 buffers before call to STREAMON in case of de-interlacing.

The motion detection block requires 3 fields to create the motion vector data. This means that using the default method the first progressive frame is only generated after 3rd field is consumed. Hence by default for N input field we would generate N - 2 progressive frames. In order to generate N progressive frames from N fields we use the line averaging mode of the de-interlacer for the first 2 fields and then revert back to the preferred Edge Directed Interpolation method (using the motion vector). Thus creating 2 line averaged frames + N - 2 motion based frames for a total of N frames.

Due to the 80-cols restrictions, and latter due to checkpatch warnings, several strings were broken into multiple lines. This is not considered a good practice anymore, as it makes harder to grep for strings at the source code. As we're right now fixing other drivers due to KERN_CONT, we need to be able to identify what printk strings don't end with a "\n". It is a way easier to detect those if we don't break long lines. So, join those continuation lines. The patch was generated via the script below, and manually adjusted if needed. </script> use Text::Tabs; while (<>) { if ($next ne "") { $c=$_; if ($c =~ /^\s+\"(.*)/) { $c2=$1; $next =~ s/\"\n$//; $n = expand($next); $funpos = index($n, '('); $pos = index($c2, '",'); if ($funpos && $pos > 0) { $s1 = substr $c2, 0, $pos + 2; $s2 = ' ' x ($funpos + 1) . substr $c2, $pos + 2; $s2 =~ s/^\s+//; $s2 = ' ' x ($funpos + 1) . $s2 if ($s2 ne ""); print unexpand("$next$s1\n"); print unexpand("$s2\n") if ($s2 ne ""); } else { print "$next$c2\n"; } $next=""; next; } else { print $next; } $next=""; } else { if (m/\"$/) { if (!m/\\n\"$/) { $next=$_; next; } } } print $_; } </script> Acked-by: NBenoit Parrot <bparrot@ti.com> Signed-off-by: NMauro Carvalho Chehab <mchehab@s-opensource.com>

The queue_setup callback has a void pointer that is just for V4L2 and is the pointer to the v4l2_format struct that was passed to VIDIOC_CREATE_BUFS. The idea was that drivers would use the information from that struct to buffers suitable for the requested format. After the vb2 split series this pointer is now a void pointer, which is ugly, and the reality is that all existing drivers will effectively just look at the sizeimage field of v4l2_format. To make this more generic the queue_setup callback is changed: the void pointer is dropped, instead if the *num_planes argument is 0, then use the current format size, if it is non-zero, then it contains the number of requested planes and the sizes array contains the requested sizes. If either is unsupported, then return -EINVAL, otherwise use the requested size(s).

It can be done with just running this shell script. replace() { str1=$1 str2=$2 dir=$3 for file in $(find $dir -name *.h -o -name *.c -o -name Makefile) do echo $file sed "s/$str1/$str2/g" $file > $file.out mv $file.out $file done } replace "videobuf2-core" "videobuf2-v4l2" "include/media/" replace "videobuf2-core" "videobuf2-v4l2" "drivers/media/" replace "videobuf2-core" "videobuf2-v4l2" "drivers/usb/gadget/" replace "videobuf2-core" "videobuf2-v4l2" "drivers/staging/media/" Signed-off-by: NJunghak Sung <jh1009.sung@samsung.com> Signed-off-by: NGeunyoung Kim <nenggun.kim@samsung.com> Acked-by: NSeung-Woo Kim <sw0312.kim@samsung.com> Acked-by: NInki Dae <inki.dae@samsung.com> Signed-off-by: NHans Verkuil <hans.verkuil@cisco.com> Signed-off-by: NMauro Carvalho Chehab <mchehab@osg.samsung.com>

1: Simplify the vpe mem-to-mem driver by using the m2m ioctl and vb2 helpers. 2: Align and arranged the v4l2_ioctl_ops. 3: Fixes a typo. 4: Use of_match_ptr() instead of explicitly defining the macro to NULL in case CONFIG_OF is not defined.
