2022-07-17media: cedrus: Add error handling for failed setupJernej Skrabec6-15/+30
During decoding setup stage for complex codecs like HEVC driver can detect inconsistent values in controls or some other task, like allocating memory, can fail. Currently setup stage has no way of signalling error. Change return type of setup callback to int and if returned value is not zero, skip decoding and finish job immediately with error flag. While currently there is only one place when setup can fail, it's expected that there will be more such cases in the future, when HEVC decoding is improved.

2022-07-17media: cedrus: h265: Fix logic for not low delay flagJernej Skrabec1-1/+26
Now that we know real purpose of "not low delay" flag, logic for applying this flag should be fixed too. According to vendor and reference implementation, low delay is signaled when POC of current frame is lower than POC of at least one reference of a slice. Implement mentioned logic and invert it to conform to flag meaning. Also don't apply flag for I frames. They don't have any reference. This fixes decoding of 3 reference bitstreams.

2022-07-17media: hantro: postproc: Fix buffer size calculationJernej Skrabec3-8/+20
When allocating aux buffers for postprocessing, it's assumed that base buffer size is the same as that of output. Coincidentally, that's true most of the time, but not always. 10-bit source also needs aux buffer size which is appropriate for 10-bit native format, even if the output format is 8-bit. Similarly, mv sizes and other extra buffer size also depends on source width/height, not destination.

2022-07-16iio: dac: cio-dac: Cleanup indexing for DAC writesWilliam Breathitt Gray1-5/+5
Simplify DAC write code by defining base member as u16 __iomem *; DAC registers are 16-bit so this allows us to index each DAC channel directly in a loop rather than calculating the offsets by multipling by 2 each time.

2022-07-16random: cap jitter samples per bit to factor of HZJason A. Donenfeld1-1/+1
Currently the jitter mechanism will require two timer ticks per iteration, and it requires N iterations per bit. This N is determined with a small measurement, and if it's too big, it won't waste time with jitter entropy because it'd take too long or not have sufficient entropy anyway. With the current max N of 32, there are large timeouts on systems with a small CONFIG_HZ. Rather than set that maximum to 32, instead choose a factor of CONFIG_HZ. In this case, 1/30 seems to yield sane values for different configurations of CONFIG_HZ.
