That's what I read as well. Is there support for U-boot to write and
Linux to read PStores?
No and yes, but U-Boot can already read pstore. Please see
doc/usage/cmd/pstore.rst for the U-Boot part, and
Documentation/admin-guide/pstore-blk.rst for the Linux kernel part.
Irrelevant, as we only want to write out the console log to U-Boot,
and
not the other way around (that's for collecting panic logs, which is
already implemented).
Another benefit of using pstore would be no permanently wasted RAM
for
the recorded console contents. Also, having the data recorded to a
storage device also goes along with providing permanent records.
I'm positively *not gonna save boot logs to disk*, as most embedded
systems have Flash-based storage media; writing to them on every boot
would be devastating. Plus, I don't want the console subsystem to
depend
on any file/disk operations/drivers.
pstore is agnostic to the backend used. In U-Boot we only support RAM
backends at the moment.
That's a very good point.
