The initial fruits of that collaboration at least are Linux kernel patches for enabling ARM64 virtualization acceleration on IBM Z servers. As we approach the end of the month, IBM has now posted a second iteration of those patches for enabling AArch64 software to run on IBM s390 via the Kernel-based Virtual Machine (KVM).<\/p>\n<p>IBM engineers today posted the second version of patches for ARM64 KVM on s390. The patches were still posted under a Request For Comments (RFC) flag and thus most likely not final form and further iterations expected before ultimately working their way potentially to the mainline kernel.\n<\/p>\n<p>The second version of these ARM64 KVM s390 patches now use symlinks for the ARM headers rather than moving them, moving some more code to s390-specific directories, and various small issues have been resolved compared to the original patches posted at the beginning of April.<br \/>\n<\/p>\n<p align=\"center\"><img decoding=\"async\" src=\"https:\/\/www.phoronix.net\/image.php?id=2026&#038;image=ibm_z\" alt=\"IBM Z servers\"\/><\/p>\n<p>So with this patch series, things are still moving along with this &#8220;dual architecture&#8221; effort of ARM64 virtualization support on IBM Z (s390) servers.<br \/>\n<br \/><a href=\"https:\/\/www.phoronix.com\/news\/ARM64-On-s390-IBM-Z-v2\">Source<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>IBM Updates Linux Patches For Introducing ARM64 KVM Virtualization On s390 https:\/\/www.phoronix.com\/news\/ARM64-On-s390-IBM-Z-v2 Publish Date: 2026-04-28&#8230;<\/p>\n","protected":false},"author":1,"featured_media":236743,"comment_status":"closed","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"fifu_image_url":"https:\/\/www.phoronix.net\/image.php?id=2026&image=ibm_z","fifu_image_alt":"","footnotes":""},"categories":[48],"tags":[71],"class_list":["post-236742","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-linux","tag-linux"],"_links":{"self":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/236742"}],"collection":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/comments?post=236742"}],"version-history":[{"count":1,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/236742\/revisions"}],"predecessor-version":[{"id":236744,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/236742\/revisions\/236744"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media\/236743"}],"wp:attachment":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media?parent=236742"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/categories?post=236742"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/tags?post=236742"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
