In v11, it was removed and the second-to-last register write was changed to a non-relaxed write, which has an implicit wmb() [1]. The rockchip_vpu2 (then rk3399_vpu) variant is even weirder as there is another writel_relaxed() following the non-relaxed one. Turns out only the last writel() needs to be non-relaxed. Device I/O mappings already guarantee strict ordering to the same endpoint, and the writel() triggering the hardware would force all writes to memory to be observed before the writel() to the hardware is observed.

This makes the driver require a bounce buffer for the encoded JPEG image scan output. Add a COM (comment) segment to the JPEG header so that the header size is a multiple of 64 bits. This will then allow dropping the use of the bounce buffer, and instead have the hardware write out to the capture buffer directly.

While it would be quite complicated to make these segments selectable to userspace, given that the driver has to fill in various fields in these segments, and also take care of alignment, it would be nice if the driver could signal to userspace what segments are included.
