Boot Loader Changes This section covers the boot loader, boot menu, and other boot-related changes. Boot Loader Changes UEFI boot is improved for amd64. The loader detects whether the loaded kernel can handle the in-place staging area (non-copying mode). The default is copy_staging auto. Auto-detection can be overridden, for example: with copy_staging enable, the loader will unconditionally copy the staging area to 2M, regardless of kernel capabilities. Also, the code to grow the staging area is more robust; for growth to occur, it’s no longer necessary to hand-tune and recompile the loader. (Sponsored by The FreeBSD Foundation) boot1 and loader have been fixed on powerpc64le. 8a62b07bce7 Other Boot Changes Performance improvements have been made to loader(8), nvme(4), random(4), rtsold(8), and x86 clock calibration, which collectively yield a significant speedup in system boot time. Configuration changes on the EC2 platform provide additional benefits, resulting in 13.1-RELEASE booting over twice as fast as 13.0-RELEASE. (Sponsored by https://www.patreon.com/cperciva https://www.patreon.com/cperciva) EC2 images are now built by default to boot using UEFI instead of legacy BIOS. Note that UEFI is not supported by Xen-based EC2 instances or by "bare metal" EC2 instances. 65f22ccf8247 (Sponsored by https://www.patreon.com/cperciva https://www.patreon.com/cperciva) Support was added for recording EC2 AMI Ids in the AWS Systems Manager Parameter Store. FreeBSD will be using the public prefix /aws/service/freebsd, resulting in parameter names which look like /aws/service/freebsd/amd64/base/ufs/13.1/RELEASE. 242d1c32e42c (Sponsored by https://www.patreon.com/cperciva https://www.patreon.com/cperciva)
