From: Dave Young on gitlab.com https://gitlab.com/cki-project/kernel-ark/-/merge_requests/1171#note_616135228 Hi David, The details of the round up is like below: For 1G-4G:xM, in kernel code we check if system_ram_size < 1G then kernel does not reserve kdump memory otherwise xM mem is reserved. But here the system_ram_size is not acurate, say a system with 1G memory installed, the system_ram_size could be 900M in kernel point of view. That will cause no kdump memory reserved. It is somehow reasonable but hard to explain to customer because people regard 1G as the system memory size. And it will be hard for QE to test as well. So we had a RHEL only patch which round up system mem size by 128M. This patch will be dropped as well. Hope this can explain the question.
