The issue and proposed fix came from a QNAP engineer working with these new embedded-focused Intel processors. The Intel Core 9 273PE was initially found to be reported for 7.0+ GHz when in reality its turbo doesn&#8217;t exceed 5.7GHz.\n<\/p>\n<p>After going through the review process, the fix for Intel Bartlett Lake with the Intel P-State driver is now queued in the Linux power management subsystem&#8217;s &#8220;linux-next&#8221; Git branch. With the Bartlett Lake fix being in that branch, it&#8217;s set to be submitted as part of the Linux 7.2 merge window in June.<br \/>\n<\/p>\n<p align=\"center\"><img decoding=\"async\" src=\"https:\/\/www.phoronix.net\/image.php?id=2026&#038;image=intel_bartlett_lake_1_med\" alt=\"Intel Bartlett Lake\"\/><\/p>\n<p>Also as part of that is a scaling factor fix for Raptor Lake E CPUs. Since late 2024 it turns out the Intel P-State driver has been incorrectly handling the scaling factor for Raptor Lake E processors. That patch too is in linux-pm.git&#8217;s linux-next branch but also marked for back-porting to the stable Linux kernel series in due course.<br \/>\n<br \/><a href=\"https:\/\/www.phoronix.com\/news\/Intel-Bartlett-Lake-P-State-7.2\">Source<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Linux 7.2 Will Fix The Intel P-State Driver For The New Bartlett Lake CPUs https:\/\/www.phoronix.com\/news\/Intel-Bartlett-Lake-P-State-7.2&#8230;<\/p>\n","protected":false},"author":1,"featured_media":247431,"comment_status":"closed","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"fifu_image_url":"https:\/\/www.phoronix.net\/image.php?id=2026&image=intel_bartlett_lake_1","fifu_image_alt":"","footnotes":""},"categories":[48],"tags":[71],"class_list":["post-247430","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\/247430"}],"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=247430"}],"version-history":[{"count":1,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/247430\/revisions"}],"predecessor-version":[{"id":247434,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/247430\/revisions\/247434"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media\/247431"}],"wp:attachment":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media?parent=247430"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/categories?post=247430"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/tags?post=247430"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
