* Loader paged/pageable data is not always paged.Toomas Soome2016-11-085-16/+27
| | | | | | | | | | | | | | | | | | | This change does modify devsw dv_print() to return the int value, enabling walkers to interrupt the walk on non zero value from dv_print(). This will allow the pager_print actually to stop displaying data on user input, and additionally pager is used in various *dev_print callbacks, where it was missing. For test, lsdev [-v] command should display data by screenfuls and should stop when the key 'q' is pressed on pager prompt.

* Really make WITHOUT_FORTH (MK_FORTH==no) work. The recent inclusion ofWarner Losh2016-10-252-0/+5
| | | | | | | | | | | | | | | FICL definitions not in ficl/ficl32 files broke this generally. This makes that stuff conditional on BOOT_FORTH. Also, move definitions related to the architecture (FICL_CPUARCH and friends) into Makefile.ficl that all parts of the tree that include files with ficl need to include (but only if MK_FORTH == yes). In addition, had to fix library ordering issue with LIBSTAND to keep it last. Without boot forth, there's no references to memset to bring in memset.o from libstand.a to satisfy libgeliboot.a's use of it. Listing libstand last solves this issue (and it's the proper place for libstand to boot). Notes: svn path=/head/; revision=307942

* loader command interpreter should reset command_errmsgToomas Soome2016-09-271-3/+5
| | | | | | | | | | | | | | | | | | | | | The command interpreter does leave command_errmsg as is after printing its content, assuming the next command will reset it in bf_command(). However, in case the forth native word is defined as builtin, the bf_command is not used and forth words will also end up the command_errmsg content printed. Since command_errmsg is pointer to actual error message, which can be static read only string, we can not just set *command_errmsg = '\0', instead we need to reset the pointer itself.

"path" then the IP of the tftp server will be the one passed by the option 150, and the files will be retrieved under "path" on the tftp server 2. "ip:path" then the IP of the tftp server will be the one passed in the option "overwritting the IP from the option 150. We could not "abuse" the rootpath option in the form or tftp://ip:path because this is already used for other purpose by iPXE preventing any chainload from iPXE to the FreeBSD loader. Given at each open(), the loader loops over all available filesystems and keep the "best" error, we needed to prevent tftpfs to fallback on nfs and vice versa. the tftpfs and nfs implementation in libstand now return EINVAL early if 'netproto' for that purpose.

* A new implementation of the loader block cacheAllan Jude2016-04-185-209/+283
| | | | | | | | | | | | | | | | | | | | 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.
