* Add SDT DTrace probes for VFS vnode operations in the vfs:vopRobert Watson2009-03-291-0/+12
| | | | | | | | | | | | | | | provider namespace. These are inserted dynamically into the VOP_..._AP() functions created from vnode_if.src. Each VOP has entry and return probes, as arg0 the primary vnode, arg1 the vnode operation argument structure pointer, providing access to IN and OUT arguments, and for return probes, arg2 the return value.

* Cleanup and document the implementation of firmware(9) based onLuigi Rizzo2007-02-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | a version that i posted earlier on the -current mailing list, and subsequent feedback received. The core of the change is just in sys/firmware.h and kern/subr_firmware.c, while other files are just adaptation of the clients to the ABI change (const-ification of some parameters and hiding of internal info, so this is fully compatible at the binary level). In detail: - reduce the amount of information exported to clients in struct firmware, and constify the pointer; - internally, document and simplify the implementation of the various functions, and make sure error conditions are dealt with properly. The diffs are large, but the code is really straightforward now (i hope). Note also that there is a subtle issue with the implementation of firmware_register(): currently, as in the previous version, we just store a reference to the 'imagename' argument, but we should rather copy it because there is no guarantee that this is a static string. I realised this while testing this code, but i prefer to fix it in a later commit -- there is no regression with respect to the past. Note, too, that the version in RELENG_6 has various bugs including missing locks around the module release calls, mishandling of modules loaded by /boot/loader, and so on, so an MFC is absolutely necessary there. I was just postponing it until this cleanup to avoid doing things twice. MFC after: 1 week Notes: svn path=/head/; revision=166756

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | and KASSERT coverage. After this check there is only one "nasty" cast in this code but there is a KASSERT to protect against the wrong argument structure behind that cast. Un-inlining the meat of VOP_FOO() saves 35kB of text segment on a typical kernel with no change in performance. We also now run the checking and tracing on VOP's which have been layered by nullfs, umapfs, deadfs or unionfs. Add new (non-inline) VOP_FOO_AP() functions which take a "struct foo_args" argument and does everything the VOP_FOO() macros used to do with checks and debugging code. Add KASSERT to VOP_FOO_AP() check for argument type being correct. Slim down VOP_FOO() inline functions to just stuff arguments into the struct foo_args and call VOP_FOO_AP(). Put function pointer to VOP_FOO_AP() into vop_foo_desc structure and make VCALL() use it instead of the current offsetoff() hack. Retire vcall() which implemented the offsetoff() Make deadfs and unionfs use VOP_FOO_AP() calls instead of VCALL(), we know which specific call we want already. Remove unneeded arguments to VCALL() in nullfs and umapfs bypass functions. Remove unused vdesc_offset and VOFFSET(). Generally improve style/readability of the generated code.

Adjust to more contemporary circumstances and gain type checking. Replace the entire vop_t frobbing thing with properly typed structures. The only casualty is that we can not add a new VOP_ method with a loadable module. History has not given us reason to belive this would ever be feasible in the the first place. Eliminate in toto VOCALL(), vop_t, VNODEOP_SET() etc. Give coda correct prototypes and function definitions for all vop_()s. Generate a bit more data from the vnode_if.src file: a struct vop_vector and protype typedefs for all vop methods. Add a new vop_bypass() and make vop_default be a pointer to another struct vop_vector. Remove a lot of vfs_init since vop_vector is ready to use from the compiler. Cast various vop_mumble() to void * with uppercase name, for instance VOP_PANIC, VOP_NULL etc. Implement VCALL() by making vdesc_offset the offsetof() the relevant function pointer in vop_vector. This is disgusting but since the code is generated by a script comparatively safe. The alternative for nullfs etc. would be much worse. Fix up all vnode method vectors to remove casts so they become typesafe. (The bulk of this is generated by scripts) Notes: svn path=/head/; revision=138290
