Reduce boot loader version string duplication

Instead of repeating "%s, Revision %s" "(%s %s)" in each loader, just create the full version string in vers.c Reviewed by: bapt MFC after: 1 month Sponsored by: The FreeBSD Foundation Differential Revision: https://reviews.freebsd.org/D8823

A new implementation of the loader block cache

2016-04-18T23:09:22Z

The block cache implementation in loader has proven to be almost useless, and in worst case even slowing down the disk reads due to insufficient cache size and extra memory copy. Also the current cache implementation does not cache reads from CDs, or work with zfs built on top of multiple disks. Instead of an LRU, this code uses a simple hash (O(1) read from cache), and instead of a single global cache, a separate cache per block device. The cache also implements limited read-ahead to increase performance. To simplify read ahead management, the read ahead will not wrap over bcache end, so in worst case, single block physical read will be performed to fill the last block in bcache. Booting from a virtual CD over IPMI: 0ms latency, before: 27 second, after: 7 seconds 60ms latency, before: over 12 minutes, after: under 5 minutes.

Give loaders more control over the Forth initialization process. In

particular, allow loaders to define the name of the RC script the interpreter needs to use. Use this new-found control to have the PXE loader (when compiled with TFTP support and not NFS support) read from ${bootfile}.4th, where ${bootfile} is the name of the file fetched by the PXE firmware. The normal startup process involves reading the following files: 1. /boot/boot.4th 2. /boot/loader.rc or alternatively /boot/boot.conf When these come from a FreeBSD-defined file system, this is all good. But when we boot over the network, subdirectories and fixed file names are often painful to administrators and there's really no way for them to change the behaviour of the loader.
