Huge performance improvements mostly for random read of mostly static content. - slog Allow to use additional disks for ZFS Intent Log to speed up operations like fsync(2). - vfs.zfs.super_owner Allows regular users to perform privileged operations on files stored on ZFS file systems owned by him. Very careful with this one. - chflags(2) Not all the flags are supported. This still needs work. - ZFSBoot Support to boot off of ZFS pool. Not finished, AFAIK. Submitted by: dfr - Snapshot properties - New failure modes Before if write requested failed, system paniced. Now one can select from one of three failure modes: - panic - panic on write error - wait - wait for disk to reappear - continue - serve read requests if possible, block write requests - Refquota, refreservation properties Just quota and reservation properties, but don't count space consumed by children file systems, clones and snapshots. - Sparse volumes ZVOLs that don't reserve space in the pool. - External attributes Compatible with extattr(2). - NFSv4-ACLs Not sure about the status, might not be complete yet. Submitted by: trasz - Creation-time properties - Regression tests for zpool(8) command. Obtained from: OpenSolaris Notes: svn path=/head/; revision=185029
* Add __elfN(relocation_offset). It holds the offset between the virtualMarcel Moolenaar2008-02-231-1/+3
| | | | | | | | | | | | | (link) address and the physical (load) address. Ideally, the mapping between link and load addresses should be abstracted by the copyin(), copyout() and readin() functions, so that we don't have to add kluges in __elfN(loadimage)(). Then, we could also have paged virtual memory for the kernel. This can be important under EFI, where you need to allocate physical memory form the firmware if you want to work in all scenarios.

This change allows a future version of libefi to work without requiring anything more than what is defined in struct devdesc and as such makes it possible to compile said version of libefi for different platforms without requiring that those platforms have identical derivatives of struct devdesc.

* Add the loader side of support for preloading ELF relocatable objectIan Dowse2004-08-291-0/+2
| | | | | | | | | | | | | format modules, which are currently only used on the amd64 platform. This initial implementation just parses enough of the module to allow it to extract dependencies and load all the bits into the right place in memory, so the kernel must still do the full relocation and linking. The details of the loaded sections are passed to the kernel by supplying a copy of the ELF section header table as module metadata with the MODINFOMD_SHDR tag. Notes: svn path=/head/; revision=134459
* Separate out the ELF relocation code from the ELF loader, and addIan Dowse2004-08-281-0/+10
| | | | | | | | | | | | better relocation support for the amd64 and i386 platforms. This should not result in any change in functionality, but moves a step towards supporting the relocatable object file modules on amd64. The same hack/trick as load_elf*.c uses is used here to simultaneously support both elf32 and elf64 on amd64 and i386. Notes: svn path=/head/; revision=134458
* Add a few helper functions for zeroing kernel space and readingIan Dowse2004-08-281-0/+3

* Enable the i386 loader to load and run an amd64 kernel. If this putsPeter Wemm2003-05-011-2/+4
| | | | | | | | | | | | | | | | | | things over floppy size limits, I can exclude it for release builds or something like that. Most of the changes are to get the load_elf.c file into a seperate elf32_ or elf64_ namespace so that you can have two ELF loaders present at once. Note that for 64 bit kernels, it actually starts up the kernel already in 64 bit mode with paging enabled. This is really easy because we have a known minimum feature set. Of note is that for amd64, we have to pass in the bios int 15 0xe821 memory map because once in long mode, you absolutely cannot make VM86 calls. amd64 does not use 'struct bootinfo' at all. It is a pure loader metadata startup, just like sparc64 and powerpc. Much of the infrastructure to support this was adapted from sparc64. Notes: svn path=/head/; revision=114379

* Declare time(not3) instead of depending on namespace pollution 3 layersBruce Evans2002-02-251-0/+2
| | | | | | | | | | | | | | | | deep in <stand.h> to eventually include <time.h> to declare the user version. This is not quite the right place to declare it, but <stand.h> would be worse because time() is very MD so it isn't in libstand. Many places in the boot sources still get the user version using only 1 layer of pollution (#include <sys/time.h>. Some pollute themselves directly (#include <time.h>). But the boot Makefiles are too broken to enable warnings for redeclarations. Notes: svn path=/head/; revision=91219

| | | | | | | | | | | | | | | | | | | | | i386 platform boots, it is no longer ISA-centric, and is fully dynamic. Most old drivers compile and run without modification via 'compatability shims' to enable a smoother transition. eisa, isapnp and pccard* are not yet using the new resource manager. Once fully converted, all drivers will be loadable, including PCI and ISA. (Some other changes appear to have snuck in, including a port of Soren's ATA driver to the Alpha. Soren, back this out if you need to.) This is a checkpoint of work-in-progress, but is quite functional. The bulk of the work was done over the last few years by Doug Rabson and Garrett Wollman.

* Make use of prototypes to silence warnings.Daniel C. Sobral1999-02-041-1/+8
| | | | | | | | | | | | | | | | | | | | | | Change include() so it will be able to load files with forth code, instead of just builtins. Remove #@- from the include section of the help file, since they don't work in the new version of include, unless BOOT_FORTH is not defined. Change bf_run() so it will return the result returned by ficlExec(). Also, make bf_run() push "interpret" to be executed by ficlExec(), since ficlExec() doesn't do it by itself. (Things worked previously because nothing recursed through ficlExec() by the way of bf_run()). Change/extend comments on builtin behavior. Search for "interpret" at the end of bf_init(), so /boot/boot.4th can provide it's own version. Remove dead code. Notes: svn path=/head/; revision=43614

* Implement a simple LRU block cache. By default this is initialised to 16k,Mike Smith1998-11-021-1/+10
| | | | | | | | | | | | | | | | | and will bypass transfers for more than 8k. Blocks are invalidated after 2 seconds, so removable media should not confuse the cache. The 8k threshold is a compromise; all UFS transfers performed by libstand are 8k or less, so large file reads thrash the cache. However many filesystem metadata operations are also performed using 8k blocks, so using a lower threshold gives poor performance. Those of you with an eye for cache algorithms are welcome to tell me how badly this one sucks; you can start with the 'bcachestats' command which will print the contents of the cache and access statistics.

This improves data-hiding. Implement a new linker-set technique (currently on i386 only but should work on Alpha as well). This is a good candidate for replacing the current gensetdefs cruft completely. Notes: svn path=/head/; revision=40553

* - VERBOSE_LS is obsolete, as the heap is much better behaved now.Mike Smith1998-10-071-1/+2
| | | | | | | | | | | | | | | | | | - Don't whine about nodes we can't stat(); these are usually symlinks that lead out of the filesystem. - Autoboot is now controlled by $autoboot_delay, which is a value in seconds or NO to disable autoboot. - Don't autoboot at the end of boot.conf if we have already tried. - Add a 'read' command to complement 'echo'. Both are still hidden. - Improve the 'source' command/function so that it is possible to source scripts off removable media. The entire script is read and saved before beginning execution. Script lines beginning with '@' will not be echoed when being executed. Script execution will normally terminate at the first error, however if the script line begins with '-' this behaviour is overriden for that command. Notes: svn path=/head/; revision=40015
* First shot at loading elf symbols. Things are a bit strange becausePeter Wemm1998-10-021-1/+3
| | | | | | | | | | | | | | | of the ..umm.. "wierd" way binutils lays out the file. The section headers are nearly at the end of the file and this is a problem when loading from a .gz file which can't seek backwards (or has a limited reverse seek, ~2K from memory). This is intended to be compatable with the ddb/db_elf.c code and the alpha/libalpha/elf_freebsd.c layout. I've studied these (which are NetBSD derived) but did it a bit differently. Naturally the process is similar since it's supposed to end up with the same result. Notes: svn path=/head/; revision=39887

These will be obsoleted when BTX is available for the 386 and the kernel load area becomes directly addressable. - Add the ability load an arbitrary file as a module, associating and arbitrary type string with it. This can be used eg. for loading splash-screen images etc. - Add KLD module dependancy infrastructure. We know how to look for dependancies inside KLD modules, how to resolve these dependancies and what to do if things go wrong. Only works for a.out at the moment, due to lack of an MI ELF loader. Attach KLD module information to loaded modules as metadata, but don't pass it to the kernel (it can find it itself). - Load a.out KLD modules on a page boundary. Only pad the a.out BSS for the kernel, as it may want to throw symbols away. (We might want to do this for KLD modules too.) - Allow commands to be hidden from the '?' display, to avoid cluttering it with things like 'echo'. Add 'echo'. - Bring the 'prompt' command into line with the parser syntax. - Fix the verbose 'ls'; it was using an uninitialised stack variable. - Add a '-v' flag to 'lsmod' to have it display module metadata as well (not terribly useful for the average user) - Support a 'module searchpath' for required modules. - The bootstrap file on i386 is now called 'loader' to permit the /boot directory to use that name. - Discard the old i386 pread() function, as it's replaced by arch_readin() Notes: svn path=/head/; revision=38764
* Bootloader update.Mike Smith1998-08-311-15/+27
| | | | | | | | | | | | | | | - Implement a new copyin/readin interface for loading modules. This allows the module loaders to become MI, reducing code duplication. - Simplify the search for an image activator for the loaded kernel. - Use the common module management code for all module metadata. - Add an 'unload' command that throws everything away. - Move the a.out module loader to MI code, add support for a.out kld modules.
