Are you using arm64 or arm32?
I'm using arm64. But also speak about arm32.
I don't understand what you mean. Looking at your log, Xen is relocated at the end of the last bank. This is the expected behavior in unstable.
Yes, I miscounted zeroes, and recalled that part before your answer ;)
This not the first time part of answer is mangled with my e-mail. This is making really difficult to follow the conversion. Can you please configure your e-mail client to do proper quote/reply?
OK. Will check it.
How were you switching between the page-tables? A proper solution would require to switch between page-tables using an identify mappings. This is far more complicate than what is worth here.
Sorry for my ignorance, what "identify mappings" stands for? Any links for the problem description? I don't remember such details of implementation but pretty sure we didn't mean that thing. It was about 3 years ago in a different company on a arm32 SoC.
Xen is free to allocate anything below 4GB. This is nothing new. But you should not have two 128MB chunks stolen because of modules here. If that's the case then there is a bug in Xen that should be fixed.
They are stolen from 1:1 memory allocation because of `allocate_memory_11()` design and implementation. -- Sincerely, Andrii Anisov. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xenproject.org https://lists.xenproject.org/mailman/listinfo/xen-devel
