After two weeks of busy merge window, Linus Torvalds has just released the first release candidate (RC-1) version of Linux 5.19 In addition to the support improvements in Intel TDx, amd sev SNP, loongarch, and big TCP, the Linux 5.19 merge window also brings many exciting new features.
(from: kernel.org official website)
Phoronix, who just celebrated his 18th birthday( https://www.phoronix.com/scan.php?page=news_item&px=Linux -5.19-rc1) the website has summarized the following highlights of Linux 5.19:
● preliminary support for Intel TDx, introducing the chip test function based on Intel field scan (IFS).
● completed the multi platform work of arm, and finally completed the mainline patch revision of AMD sev-snp after a year.
● provide firmware level zstd compression support, initial CPU migration of loongarch architecture, and ntfs3 driver repair.
● continue to promote support for AMD rdna3 and Intel DG2 / alchemist GPU.
● improve apple M1 nvme support and the correct file creation / birth time report of FAT32 file system.
● big TCP merges, implements the kernel side support of armv9's scalable matrix extension, etc.
Git statistics on the day showed that Linux 5.19-rc1 added 1.04 million lines and removed 256000 lines of code, slightly higher than the previous Linux 5.18 merge window.
Linus Torvalds commented in the announcement:
Although I will complain about how many extension requests have been received, the past two weeks have been generally 'normal'. The situation in the second week was very calm at the beginning, but it was only because many people delayed their requests until late.
I am very happy that almost all query requests have been marked [... ] we are achieving our goals, and we are making good progress in finishing the work. The good news is that this is the first merge window in which Andrew fully participates through git, and I don't have a "patch bomb" to deploy (or for the first time in the history of Linux).
[... ] overall, everything is pretty good.
Finally, if all goes well, the Linux 5.19 stable kernel is expected to be released before the end of July. The reason why this update is so large is that a large number of graphics drivers have been added.
