Boot time: Kernel start parallelization issue?
|[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]|
There are some reports   looking at the boot time of embedded (ARM?) systems using initcall debug . Both reports seem to show that they have issues with the start up sequence of the kernel being completely single-threaded. In  Greg mentions that on a x86 box multi-threads are happening and that there he doesn't see this issue. On the other hand, both reports mention Arjan's async initcall patches  to help against the issue. I.e. introducing some parallelization (on ARM) does help, too.
With this, I wonder- if anybody faces similar issues with single-threaded only kernel start on embedded (ARM?) systems? Or if this is known? Or if there are fixes for this?
- if we somehow should try to 're-activate' Arjan's async initcall patches?
Any ideas? Many thanks and best regards DirkP.S.: I couldn't find a mail address of Alex Gonzalez, the author of , to put him into CC. If anybody knows him, please feel free to add him to this thread. Thanks!
