AGESA updates can be useful for new performance optimizations, expanding system memory compatibility, CPU security features, new CPU support, etc.<br \/>\n<\/p>\n<p align=\"center\"><img decoding=\"async\" src=\"https:\/\/www.phoronix.net\/image.php?id=2024&#038;image=amd_agesa_9950x_sml\" alt=\"AMD AGESA version in BIOS\"\/><\/p>\n<p>Finally with Linux 7.1, the AGESA version when detected will be printed to the kernel log. Thus with the Linux kernel moving forward on AMD Zen systems it can be a simple matter of grep&#8217;ing the kernel log, e.g. sudo dmesg | grep AGESA for quickly and easily determining your AGESA version under Linux.<\/p>\n<p>This patch providing the AGESA reporting based on the DMI additional information data is queued into tip\/tip.git&#8217;s x86\/platform Git branch. With the support now found in a TIP branch, it should be submitted for the Linux 7.1 merge window kicking off as soon as next week.\n<\/p>\n<p>It would be great if the AGESA version was also reported under \/sys\/class\/dmi\/id\/ for non-root access and easier parsing, such as I&#8217;ve wanted the information for many years in the interest of benchmark reporting\/transparency as part of the system information, but perhaps that will come in the future.<\/p>\n<p><a href=\"https:\/\/www.phoronix.com\/news\/AMD-AGESA-Version-Linux-7.1\">Source<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>A Small But Useful Debugging Addition For AMD Zen Systems With Linux 7.1 https:\/\/www.phoronix.com\/news\/AMD-AGESA-Version-Linux-7.1 Publish&#8230;<\/p>\n","protected":false},"author":1,"featured_media":231836,"comment_status":"closed","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"fifu_image_url":"https:\/\/www.phoronix.net\/image.php?id=2024&image=amd_agesa_9950x","fifu_image_alt":"","footnotes":""},"categories":[48],"tags":[71,57],"class_list":["post-231835","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-linux","tag-linux","tag-security"],"_links":{"self":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/231835"}],"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=231835"}],"version-history":[{"count":1,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/231835\/revisions"}],"predecessor-version":[{"id":231837,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/231835\/revisions\/231837"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media\/231836"}],"wp:attachment":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media?parent=231835"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/categories?post=231835"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/tags?post=231835"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
