| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | version dependency system. This isn't quite finished, but it is at a useful stage to do a functional checkpoint. Highlights: - version and dependency metadata is gathered via linker sets, so things are handled the same for static kernels and code built to live in a kld. - The dependencies are at module level (versus at file level). - Dependencies determine kld symbol search order - this means that you cannot link against symbols in another file unless you depend on it. This is so that you cannot accidently unload the target out from underneath the ones referencing it. - It is flexible enough that we can put tags in #include files and macros so that we can get decent hooks for enforcing recompiles on incompatable ABI changes. eg: if we change struct proc, we could force a recompile for all kld's that reference the proc struct. - Tangled dependency references at boot time are sorted. Files are relocated once all their dependencies are already relocated. Caveats: - Loader support is incomplete, but has been worked on seperately. - Actual enforcement of the version number tags is not active yet - just the module dependencies are live. The actual structure of versioning hasn't been agreed on yet. (eg: major.minor, or whatever) - There is some backwards compatability for old modules without metadata but I'm not sure how good it is. This is based on work originally done by Boris Popov (bp@freebsd.org), but I'm not sure he'd recognize much of it now. Don't blame him. :-) Also, ideas have been borrowed from Mike Smith.

* A hack basically.. We have a bunch of code that used to callPeter Wemm1999-11-081-1/+8
| | | | | | | | | | | | | | devsw_module_handler() indirectly and not use the chain arguments. To eliminate this indirection via that function (which does nothing now) without duplicating a modevent handler into all the routines that don't presently have one, supply a NOP (do nothing, return OK) routine which is functionally equivalent to what's there now. This is a hack and is still wrong, because there doesn't appear to be anything to reclaim resources on an unload of a module with one of these in it. I'm not sure whether to make the NOP handler refuse a MOD_UNLOAD event or what. Notes: svn path=/head/; revision=52991

* First stages of a module dependency cleanup. This part fixes aPeter Wemm1999-05-081-21/+33
| | | | | | | | | | | | | | | particularly annoying hack, namely having the linker bash the moduledata to set the container pointer, preventing it being const. In the process, a stack of warnings were fixed and will probably allow a revisit of the const C_SYSINIT() changes. This explicitly registers modules in files or preload areas with the module system first, and let them initialize via SYSINIT/DECLARE_MODULE later in their SI_ORDER_xxx order. The kludge of finding the containing file is no longer needed since the registration of modules onto the modules list is done in the context of initializing the linker file.

| | | | | | | | | | | This is the bulk of the support for doing kld modules. Two linker_sets were replaced by SYSINIT()'s. VFS's and exec handlers are self registered. kld is now a superset of lkm. I have converted most of them, they will follow as a seperate commit as samples. This all still works as a static a.out kernel using LKM's. Notes: svn path=/head/; revision=40435
* Keep track of the containing file for modules. This is a bit of a hack,Peter Wemm1998-10-101-7/+11
| | | | | | | | | | but I can't think of another (relatively) easy way of getting the info since the boot-time initialization is not done immediately after "loading". XXX module_register() gained an extra arg. This might break the alpha compile, if so, just add a zero to get the old behavior. Notes: svn path=/head/; revision=40158
