According to BSP library source, H264 neighbour info buffer size needs to be 32 kiB for H6. This is similar to H265 decoding, which also needs double buffer size in comparison to older Cedrus core generations. Increase buffer size to cover H6 needs. Since increase is not that big in absolute numbers, it doesn't make sense to complicate logic for older generations. Issue was discovered using iommu and cross checked with BSP library source.

Some cx88 video cards may have transport stream status interrupts set to 1 from cold start, causing errors like this: cx88xx: cx88_print_irqbits: core:irq mpeg [0x100000] ts_err?* cx8802: cx8802_mpeg_irq: mpeg:general errors: 0x00100000 According to CX2388x datasheet, the interrupt status register should be cleared before enabling IRQs to stream video. Fix it by clearing the Transport Stream Interrupt Status register. Signed-off-by:Daniel González Cabanelas <dgcbueu@gmail.com>

Neighbour info buffer size needs to be 794 kiB in H6. This is actually already indirectly mentioned in the comment, but smaller size is used nevertheless. Increase buffer size to cover H6 needs. Since increase is not that big in absolute numbers, it doesn't make sense to complicate logic for older generations. Bug was discovered using iommu, which reported access error when trying to play H265 video. Fixes: 86caab29 ("media: cedrus: Add HEVC/H.265 decoding support") Signed-off-by:

When error occurs in parsing jpeg, the slot isn't acquired yet, it may be the default value MXC_MAX_SLOTS. If the driver access the slot using the incorrect slot number, it will access array out of bounds. The result is the driver will change num_domains, which follows slot_data in struct mxc_jpeg_dev. Then the driver won't detach the pm domain at rmmod, which will lead to kernel panic when trying to insmod again. Signed-off-by:

The commit 47677e51("[media] em28xx: Only deallocate struct em28xx after finishing all extensions") adds kref_get to many init functions (e.g., em28xx_audio_init). However, kref_init is called too late in em28xx_usb_probe, since em28xx_init_dev before will invoke those init functions and call kref_get function. Then refcount bug occurs in my local syzkaller instance. Fix it by moving kref_init before em28xx_init_dev. This issue occurs not only in dev but also dev->dev_next.

Current settings for video capture rgb-2-yuv is BT.601(studio swing), but JFIF uses BT.601(full swing) to deocde. This mismatch will lead to incorrect color. For example, input RGB value, (0, 0, 255), will become (16, 16, 235) after jpg decoded. Add an enum, aspeed_video_capture_format, to define VR008[7:6] capture format and correct default settings for video capture to fix the problem. VR008[7:6] decides the data format for video capture as below: * 00: CCIR601 studio swing compliant YUV format * 01: CCIR601 full swing compliant YUV format * 10: RGB format * 11: Gray color mode Signed-off-by:

When Gen3 support was first added to this R-Car VIN and CSI-2 driver the routing was centred around the CHSEL register which multiplexes the different parallel buses that sit between the CSI-2 receivers source side and the VIN dma engines. This was a bad design as the multiplexing do allow for only a few combinations and do not play nice with many video streams in the system. For example it's only possible for CSI-2 Virtual Channels 0 and 1 of any given CSI-2 receiver to be used together with the scaler. Later datasheets have expanded the documentation and it is now possible to improve on this design by allowing any Virtual Channel to be routed to any R-Car VIN instance, provided that there exists a parallel bus between them. This increases the flexibility as all Virtual Channels can now be used together with the scaler for example. The redesign is not however perfect. While the new design allows for many more routes, two constrains limit a small portion of routes that was possible in the old design but are no more. - It is no longer possible to route the same CSI-2 and VC to more then one VIN at a time. This was theoretically possible before if the specific SoC allowed for the same CSI-2 and VC to be routed to two different VIN capture groups. - It is no longer possible to simultaneously mix links from two CSI-2 IP blocks to the same VIN capture group. For example if VIN2 is capturing from CSI40 then VIN{0,1,3} must also capture from CSI40. While VIN{4,5,6,7} is still free to capture from any other CSI-2 IP in the system. Once all VIN{0,1,2,3} links to CSI40 are disabled that VIN capture group is free again to capture from any other CSI-2 IP it is connected to. At the core of the redesign is greater cooperator of the R-Car VIN and CSI-2 drivers in configuring the routing. The VIN driver is after this change only responsible to configure the full VIN capture groups parallel buses to be to a particular CSI-2 IP. While the configuration of which CSI-2 Virtual Channel is outputted on which of the R-Car CSI-2 IP output ports is handled by the CSI-2 driver. Before this change the CSI-2 Virtual Channel to output port was static in the CSI-2 driver and the different links only manipulated the VIN capture groups CHSEL register. With this change both the CHSEl register and the CSI-2 routing VCDT registers are modified for greater flexibility. This change touches both the R-Car VIN and R-Car CSI-2 drivers in the same commit as both drivers cooperate closely and one change without the other would more or less break video capture.

The code has grown organically and a lot of checks are performed for the CSI-2 use-case even if the link notify is for a subdevice connected to the parallel interface. Before reworking the CSI-2 routing logic split the CSI-2 and parallel link notify code in two separate blocks to make it clearer. There is no functional change. Signed-off-by:
