There wasn&#8217;t much to report over the past three months on this work but today a second iteration of the patches emerged on the Linux kernel mailing list.<\/p>\n<p>As opposed to the current behavior of package-level thermal interrupts being broadcast to all CPU cores, Directed Package Thermal Interrupts allow for broadcasting to just one CPU core tasked for handling the package-wide events. In turn this feature will allow for reduced resource contention and can avoid needlessly waking up possible idle CPU cores.<br \/>\n<\/p>\n<p align=\"center\"><img decoding=\"async\" src=\"https:\/\/www.phoronix.net\/image.php?id=intel-core-ultra-9-285k-linux&#038;image=core_ultra_285k_9_med\" alt=\"Intel desktop CPU socket\"\/><\/p>\n<p>So far I haven&#8217;t seen any definitive indications what Intel CPUs support this feature. While the patches note that &#8220;newer&#8221; Intel CPUs support it, other indicators point it coming out with upcoming Nova Lake and Diamond Rapids processors.<\/p>\n<p>The new v2 Linux patches for Directed Package Thermal Interrupt fix various bugs in the prior code and other code clean-ups.\n<\/p>\n<p>Given the timing of this v2 patch series, we&#8217;ll see how this latest round of code review goes and if this functionality makes to make it into the upcoming Linux v7.2 merge window.<\/p>\n<p><a href=\"https:\/\/www.phoronix.com\/news\/Intel-Directed-Pkg-Therm-Inter\">Source<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Intel Sends Out Revised Linux Patches For Directed Package Thermal Interrupts https:\/\/www.phoronix.com\/news\/Intel-Directed-Pkg-Therm-Inter Publish Date: 2026-05-28&#8230;<\/p>\n","protected":false},"author":1,"featured_media":258301,"comment_status":"closed","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"fifu_image_url":"https:\/\/www.phoronix.net\/image.php?id=intel-core-ultra-9-285k-linux&image=core_ultra_285k_9","fifu_image_alt":"","footnotes":""},"categories":[48],"tags":[71],"class_list":["post-258300","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\/258300"}],"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=258300"}],"version-history":[{"count":1,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/258300\/revisions"}],"predecessor-version":[{"id":258302,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/258300\/revisions\/258302"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media\/258301"}],"wp:attachment":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media?parent=258300"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/categories?post=258300"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/tags?post=258300"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
