The RISC-V defconfig is updated to now include this Eswin SoC support with the developer motivation in wanting to ensure the default RISC-V kernel builds support the popular SiFive HiFive Premier P550 board.<br \/>\n<\/p>\n<p align=\"center\"><img decoding=\"async\" src=\"https:\/\/www.phoronix.net\/image.php?id=sifive-hifive-premier-p550&#038;image=sifive_hifive_p550_1_med\" alt=\"SiFive Premier P550\"\/><\/p>\n<p>RISC-V meets all the requirements for HAVE_BUILDTIME_MCOUNT_SORT and by setting it, the sort table is able to sort the __mcount_loc section at link time that in turn reduces kernel start-up overhead within the ftrace initialization path.<\/p>\n<p>RISC-V for this next kernel version also has a number of code clean-ups, fixing a potential memory leak in the cacheinfo code, and various fixes.\n<\/p>\n<p>The full list of RISC-V feature changes for Linux 7.2 can be found via this pull request.<\/p>\n<p><a href=\"https:\/\/www.phoronix.com\/news\/Linux-7.2-RISC-V\">Source<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Linux 7.2 RISC-V Reduces Kernel Startup Overhead, Eswin SoC Support By Default https:\/\/www.phoronix.com\/news\/Linux-7.2-RISC-V Publish Date:&#8230;<\/p>\n","protected":false},"author":1,"featured_media":279359,"comment_status":"closed","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"fifu_image_url":"https:\/\/www.phoronix.net\/image.php?id=sifive-hifive-premier-p550&image=sifive_hifive_p550_1","fifu_image_alt":"","footnotes":""},"categories":[48],"tags":[71],"class_list":["post-279356","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\/279356"}],"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=279356"}],"version-history":[{"count":1,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/279356\/revisions"}],"predecessor-version":[{"id":279362,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/279356\/revisions\/279362"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media\/279359"}],"wp:attachment":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media?parent=279356"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/categories?post=279356"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/tags?post=279356"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
