https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=222807 --- Comment #6 from Conrad Meyer <cem@freebsd.org> --- So hc_source_mask is initialized to RANDOM_HARVEST_EVERYTHING_MASK. Is expanding RANDOM_HARVEST_EVERYTHING_MASK to cover the Pure devices sufficient to harvest from RDRAND and Via? Or would that break anything (e.g., due to the devices that did not register)? Yes, the rest of the 1st patch is a nice enhancement to expose those bits to userspace that were not exposed before. I'm just not clear on if the bits must only be set on registration, or if it's ok to just have them all set from the beginning. Thanks! Would you mind throwing the patches up on Phabricator so comments can be more clearly associated with specific lines of code? -- You are receiving this mail because: You are the assignee for the bug.
