sendHistogramChannelIoctl spams log

miles992

I have a Pixel 8 with the latest GrapheneOS installed, since the last update I see an endless stream of "sendHistogramChannelIoctl" and "getHistogramData" items floating by.

The message reads:

hwc-display: sendHistogramChannelIoctl:
kernel doesn't support multi channel histogram ioctl
hwc-display: getHistogramData:
histogram channel #0: BAD_HIST_DATA, sendHistogramChannelIoctl (REQUEST) error (-38)

Anyone got an idea what this is?

Hi there, do you have a GitHub account? If so, would you mind reporting it there please? That is the proper place for bug reports:
