  • The parameters section mentions nslotp, but there is no such parameter in any of the callbacks.
  • Either I'm slow today or this sentence is hard to parse: "A buffer to place data firmware data read into."
  • The first graph goes to some length to make it clear that images are not just "firmware" (even though this subsystem is named the Upgradable Firmware Module). However, the rest of the man page wavers between referring to them as "image(s)" or "firmware image(s)". This doesn't seem to interfere with my understanding of how things work -- I get the gist -- but this slight dissonance might throw someone for a loop. Just a thought.
  • "...image can be downloaded to the device without impacting the [current device] if it fails..." I'm pretty sure this should be either "current image" (or maybe "active image") or "device".
  • "If a driver indicates support for multiple images [or slots]..." From what I can tell there is no way to a driver to indicate the number of slots for a given image (this gets back to the missing nslotp, perhaps in the past there was a way to specify this data. But the current API seems to dictate that rather you simply return an error if the consumer requests a bogus slot number.
  • There are three sentences which start "This [attributes] indicates".
  • The man page uses imgid and slotid, but drivers seem to prefer to use imgno/slotno. Might be nice to change the man page to use the most common naming scheme.
  • Under the ddi_ufm_op_getcaps() section, specifically for the DDI_UFM_CAP_REPORT cap, it implies that the ddi_ufm_op_fill_image is optional. Yet the ddi_ufm_init() implementation specifically VERIFYs that this callback is not NULL. Furthermore, is it ever the case that a device doesn't implement the DDI_UFM_CAP_REPORT? What would be the reason for such a decision?
  • "it need know that it has" I can't parse this.
  • "...adequate locking to its structure members as [others] may be accessing..."
