* A new implementation of the loader block cacheAllan Jude2016-04-181-2/+2
| | | | | | | | | | | | | | | | | | | | 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. InMarcel Moolenaar2014-07-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | 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.

* Add 2 new archsw interfaces:Marcel Moolenaar2011-04-031-0/+17
| | | | | | | | | | | | | | | | | 1. arch_loadaddr - used by platform code to adjust the address at which the object gets loaded. Implement PC98 using this new interface instead of using conditional compilation. For ELF objects the ELF header is passed as the data pointer. For raw files it's the filename. Note that ELF objects are first considered as raw files. 2. arch_loadseg - used by platform code to keep track of actual segments, so that (instruction) caches can be flushed or translations can be created. Both the ELF header as well as the program header are passed to allow platform code to treat the kernel proper differently from any additional modules and to have all the relevant details of the loaded segment (e.g. protection).
