Then, does it answered your question? 256M is set as a default value in the patch, but it is not a predict to satisfy all use cases, from the description it is also possible that some people run out of the 256M and the ,low and ,high format is still necessary to exist even if we make crashkernel=X do the allocation automatically in high in case failed in low area. crashkernel=X: allocate in low first, if not possible, then allocate in high In case people have a lot of devices need more swiotlb, then he manually set the ,high with ,low together. What's your suggestion then? remove ,low and ,high and increase default 256M in case we get failure bug report? _______________________________________________ kexec mailing list kexec@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/kexec
