<wens>
colleague said DT should support maps/dictionaries to simplify writing X + X-names lol
<maz>
wens: we should make DT Turing-complete. at this point, who needs the actual HW?
<javierm>
maz: then you could implement a forth interpreter in DT and use a trully OF blob

What mechanism does a pKVM guest use to share memory with other domains?
<ajb-linaro>
I'm guessing it's not pkvm_create_private_mapping?
<ajb-linaro>
ahh pkvm_host_share_hyp?
biju has quit [Ping timeout: 260 seconds]
<maz>
ajb-linaro: if by domain you mean another guest, the answer is *none*.
<maz>
it can only share back with the host.
<maz>
the host can share with hyp too, of course.

<ajb-linaro>
maz for now guests sharing to the host will do - I guess pKVM isn't thinking about supporting driver domains?
<ajb-linaro>
maz when you share with the host is there any mechanism for userspace to map those pages?
snalty has joined #armlinux
<maz>
ajb-linaro: the same as normal KVM. it is userspace that provides the mapping anyway.
<cambrian_invader>
would also be much easier to specify in dt-schema

<cambrian_invader>
wens: no, this is just an example
<cambrian_invader>
but devicetree *does* have maps
<cambrian_invader>
they just aren't always used
<robmur01>
heh, calling the node/property/value structure a map seems a bit like saying C has polymorphism...
<robmur01>
technically true, but not fit for arbitrary usage :)

Hi. I'm trying to reduce boot time on emulation(zebu).
<rfried>
Most of the kernel boot time is around the mapping of ddr pages, but I couldn't understand why. I assumed it used hugetables so it should take so long.
<rfried>
Lowering the mapped DDR from 8GB to 2GB significantly reduced the boot time.
<rfried>
Anyone knows if there's something slow hiding there, perhaps clearing the pages or something?

<balrog>
what is the correct way to bump the version of a -git AUR package when the upstream repo hasn't changed?
<balrog>
(e.g. to fix a PKGBUILD issue)
<balrog>
bump pkgre?
<balrog>
pkgrel*
<heat>
yeah I think so, that sounds correct. just like a normal package
