There&#8217;s a little bit of everything from graphics drivers to file-systems and all the other random hardware churn.&#13;<\/p>\n<p>One change found in Linux 6.13-rc3 is the partial step for what I covered this morning of <a href=\"https:\/\/www.phoronix.com\/news\/Linux-Intel-KVM-Cache-CPUID\">a &#8220;hilarious\/revolting performance regression&#8221;<\/a> discovered by Google engineers with recent Intel Xeon CPUs having &#8220;wildly expensive&#8221; CPUID costs. Linux 6.14 will have a full workaround while for Linux 6.13-rc3 the Kernel-based Virtual Machine (KVM) will rely on CPUID caching to speed things up to help Intel Xeon processors.&#13;<\/p>\n<p align=\"center\"><img decoding=\"async\" src=\"https:\/\/www.phoronix.net\/image.php?id=2024&amp;image=linux_613_rc3\" alt=\"Linux 6.13-rc3 Git tag\"\/><\/p>\n<p>As for Linux 6.13-rc3 at large, Linus Torvalds commented in the <a href=\"https:\/\/lore.kernel.org\/lkml\/CAHk-=wh7Wjqo_e1bLeEijGkDaw7XcD3+F5kLZYkJfah8wS=evg@mail.gmail.com\/T\/#u\">release announcement<\/a>:<br \/>\n<\/p>\n<blockquote><p>&#8220;Earlier this week it felt to me like things might have already started to quiet down in prep for the holidays, but doing the statistics on rc3 that doesn&#8217;t actually seem to be the case &#8211; this looks very regular both in number of commits and in diff size. In fact, the diff is  a bit on the larger side, but that is admittedly almost entirely due to the revert of a unicode change that then makes the diff large due to a generated data file.&#13;<\/p>\n<p>So everything looks normal so far. xfs may stand out in the shortlog below, but the bulk of the diff (ignoring that generated unicode table) is still mostly random driver updates.&#8221;<\/p>\n<\/blockquote>\n<p>See the <a href=\"https:\/\/www.phoronix.com\/review\/linux-613-features\">Linux 6.13 feature overview<\/a> to learn more about the kernel changes overall that are new to the Linux 6.13 kernel.<\/div>\n<p><script async src=\"https:\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-3711241968723425\"\r\n     crossorigin=\"anonymous\"><\/script>\r\n<ins class=\"adsbygoogle\"\r\n     style=\"display:block\"\r\n     data-ad-format=\"fluid\"\r\n     data-ad-layout-key=\"-fb+5w+4e-db+86\"\r\n     data-ad-client=\"ca-pub-3711241968723425\"\r\n     data-ad-slot=\"7910942971\"><\/ins>\r\n<script>\r\n     (adsbygoogle = window.adsbygoogle || []).push({});\r\n<\/script><br \/>\n<br \/><div data-type=\"_mgwidget\" data-widget-id=\"1660802\">\r\n<\/div>\r\n<script>(function(w,q){w[q]=w[q]||[];w[q].push([\"_mgc.load\"])})(window,\"_mgq\");\r\n<\/script>\r\n<br \/>\n<br \/><a href=\"https:\/\/www.phoronix.com\/news\/Linux-6.13-rc3-Released\">Source link <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Linus Torvalds announced the release this evening of the Linux 6.13-rc3 kernel as Linux 6.13 works its way to stable release by late January.
