How to use io-uring

[jack206]

I want to use io-uring in dbus-sensors, My boost version is 1.78.0, How do I use boost version 1.79.0 alone in dbus-senos？

The project is trying to access the directory subprojects/boost_1_79_0/ which belongs to a different	subproject. This is a problem as it hardcodes the relative paths of these two projects.	This makes it impossible to compile the project in any other directory layout and also	prevents the subproject from changing its own directory layout.
Instead of poking directly at the internals the subproject should be executed and
it should set a variable that the caller can then use. Something like:
# In subproject
some_dep = declare_dependency(include_directories: include_directories('include'))
# In subproject wrap file
[provide]
some = some_dep
# In parent project
some_dep = dependency('some')
executable(..., dependencies: [some_dep])
This warning will become a hard error in a future Meson release.

You can’t use an old release and then expect to be able to update random packages. There are tight dependencies within the image on a particular version of boost. You can’t [easily] update that independently (or at least it isn’t a use case we are going to support).

[jack206]

I have updated to boost1.79.0, but psusensor is also blocking, it seems that io_uring is not effective, how can I confirm that io_uring is effective?

[edtanous]

Use a real openbmc release. You should not be mixing and matching boost. Use what’s given.

Has anyone cached sensor values with unordered_map？ Like https://github.com/openbmc/docs/blob/6b367a2f9b5fe3e103a51d584111a7f569073f90/designs/phosphor-hwmon-io-uring.md?plain=1#L4
