When refactoring the Gen3 enablement series crop and compose handling where broken. This went unnoticed but can result in writing out side the capture buffer. Fix this by restoring the crop and compose to reflect the format dimensions as we have not yet enabled the scaler for Gen3. Fixes: 5e7c6236 ("media: rcar-vin: use different v4l2 operations in media controller mode") Reported-by:

The offending commit was an attempt to fix the issue of writing outside the capture buffer for VIN Gen3. Unfortunately it only fixed the symptom of the problem to such a degree I could no longer reproduce it. Revert the offending commit before a proper fix can be added in a follow-up patch.

This bug affects all of Hauppauge QuadHD boards when used on all Ryzen platforms and some XEON platforms. On these platforms it is possible to error out the RiSC engine and cause it to stall, whereafter the only way to reset the board to a working state is to reboot.

On Ryzen systems interrupts are occasionally missed: cx23885: cx23885_wakeup: [ffff99b384b83c00/28] wakeup reg=5406 buf=5405 cx23885: cx23885_wakeup: [ffff99b40bf79400/31] wakeup reg=9537 buf=9536 This patch loops up to five times on wakeup, marking any buffers found done. Since the count register is u16, but the vb2 counter is u32, some modulo arithmetic is used to accommodate wraparound and ensure current active buffer is the buffer expected. Signed-off-by:

The mdev field is only present if CONFIG_MEDIA_CONTROLLER is set. But since we will need to pass the media_device to vb2 and the control framework it is very convenient to just make this field available all the time. If CONFIG_MEDIA_CONTROLLER is not set, then it will just be NULL. Signed-off-by:

Arnd Bergmann authored
C libraries with 64-bit time_t use an incompatible format for struct omap3isp_stat_data. This changes the kernel code to support either version, by moving over the normal handling to the 64-bit variant, and adding compatiblity code to handle the old binary format with the existing ioctl command code. Fortunately, the command code includes the size of the structure, so the difference gets handled automatically. In the process of eliminating the references to 'struct timeval' from the kernel, I also change the way the timestamp is generated internally, basically by open-coding the v4l2_get_timestamp() call.

This issue was reported by a user who downloaded a corrupt saa7164 firmware, then went looking for a valid xc5000 firmware to fix the error displayed...but the device in question has no xc5000, thus after much effort, the wild goose chase eventually led to a support call. The xc5000 has nothing to do with saa7164 (as far as I can tell), so replace the string with saa7164 as well as give a meaningful hint on the firmware mismatch. Signed-off-by:

The renesas-ceu driver intializes the desired mbus_format at 'complete' time, inspecting the supported subdevice ones, and tuning some parameters to produce the requested memory format from what the sensor can produce. Although, the initially selected mbus_format was not provided to the subdevice during set_fmt and try_fmt operations, providing instead a '0' mbus format code. As long as the sensor defaults to a compatible mbus_format when an invalid code as '0' is provided, capture operations work correctly. If the subdevice defaults to an unsupported format (eg. some RGB permutations) capture does not work properly due to a mismatch on the expected and received image format on the wire. Fix that by re-using the initially selected mbus_format code during set_fmt and try_fmt subdevice operation calls. Tested by printing out the format selection procedure with ov7670 sensor.

This reverts commit fc7f8fd4. Whilst the rationale for the above commit was in general correct, i.e. that users *consuming* the DMA addresses should rely on sglen rather than num_pages, it has always been the case that the DMA API itself still requires that dma_{sync,unmap}_sg() are called with the original number of entries as passed to dma_map_sg(), not the number of mapped entries it returned. Thus the particular changes made in that patch were erroneous. At worst this might lead to data loss at the tail end of mapped buffers on non-coherent hardware, while at best it's an example of incorrect DMA API usage which has proven to mislead readers.
