Now being worked on by AMD engineers, this accelerated page migration via batch copies and hardware offloading continues to show promising results.<\/p>\n<p>AMD engineer Shivank Garg posted the latest request for comments (RFC) patches on speeding up page migration in the Linux kernel by batching folio-copy operations and providing accelerated hardware offloading using the DMA offload interface.  The intent is for overcoming the current Linux kernel behavior of single-threaded, folio-by-folio copies in the kernel. As part of the patch series is an example\/reference DMA offload driver &#8220;DCBM&#8221;\n<\/p>\n<p>With the new RFC v5 patches, various code improvements have been made and the patches re-based against the Linux 7.1-rc1 Git state. The performance is reportedly unchanged from the v4 patches, which showed much potential from this patch series when tested on an EPYC Zen 3 server:<br \/>\n<\/p>\n<p align=\"center\"><img decoding=\"async\" src=\"https:\/\/www.phoronix.net\/image.php?id=2026&#038;image=accel_page_migration\" alt=\"benchmark results for accelerated page migration\"\/><\/p>\n<p>Those interested can find these latest accelerated page migration patches on the Linux kernel mailing list.<br \/>\n<br \/><a href=\"https:\/\/www.phoronix.com\/news\/Accelerated-Page-Migration-v4\">Source<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>AMD Posts Newest Linux Patches To Accelerate Page Migration For Better Performance https:\/\/www.phoronix.com\/news\/Accelerated-Page-Migration-v4 Publish Date:&#8230;<\/p>\n","protected":false},"author":1,"featured_media":243197,"comment_status":"closed","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"fifu_image_url":"https:\/\/www.phoronix.net\/image.php?id=2026&image=accel_page_migration","fifu_image_alt":"","footnotes":""},"categories":[48],"tags":[71],"class_list":["post-243196","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\/243196"}],"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=243196"}],"version-history":[{"count":1,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/243196\/revisions"}],"predecessor-version":[{"id":243198,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/243196\/revisions\/243198"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media\/243197"}],"wp:attachment":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media?parent=243196"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/categories?post=243196"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/tags?post=243196"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
