Linux 5.19 welcomes its first release candidate.

Linus Torvalds has just released the first release candidate (rc-1) version of Linux 5.19 after a busy two-week merge window. In addition to support improvements for Intel TDX, AMD SEV-SNP, LoongArch, Big TCP, the Linux 5.19 merge window brings many exciting new features.

The Phoronix website, which just celebrated its 18th birthday , has compiled the following highlights of Linux 5.19:

● Preliminary support for Intel TDX, the introduction of Intel Field Scan (IFS)-based chip test function.

● Completed the multi-platform work of ARM, and finally completed the mainline patch revision of AMD SEV-SNP after a year.

● Provides firmware-level Zstd compression support, initial CPU porting for LoongArch architecture, NTFS3 driver fixes.

● Continued work on support for AMD RDNA3 and Intel DG2 / Alchemist GPUs.

● Improved Apple M1 NVMe support, correct file creation/birth time reporting for FAT32 file system.

● Big TCP merge, implement the kernel-side support for Armv9’s Scalable Matrix Extension, etc.

Git statistics for the day show that Linux 5.19-rc1 added 1.04 million lines and removed 256,000 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 ‘underwhelming’. The second week started very calmly, but that was only because a lot of people dragged their pull requests to a later date.

I am very happy that almost all query requests are already marked. […] We’re on track, and we’re making pretty good progress with the finishing touches.

The good news is that this is the first merge window where Andrew is fully involved through git, and I don’t have a ‘patch bomb’ to deploy (or for the first time in Linux history).

[…] Overall, everything is pretty good.

Finally, if all goes well, the Linux 5.19 stable kernel is expected to be released by the end of July. And the reason why this update is so big is mainly the large number of additions in terms of graphics drivers.
