Right, if the user manually specifies "cma=2G" and the system is not able to cope with that, this is a clear configuration error and once supported, we would want to document that -- there are other cases where having too much CMA memory can be problematic. Regarding s390x/cma: they reserve other CMA regions, not the default one (cmd=XX); we'd want to specify: - vmcp_cma=0 on s390x - kvm_cma_resv_ratio=0 on ppc64 However, the s390x version is not too bad (-> 4 MiB), so maybe we want to leave that untouched. _______________________________________________ kernel mailing list -- kernel@lists.fedoraproject.org To unsubscribe send an email to kernel-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/kernel@lists.fedoraproject.org Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
