An OBJT_SG object is very similar to a device pager (OBJT_DEVICE) object in that it uses fictitious pages to provide aliases to other memory addresses. The primary difference is that it uses an sglist(9) to determine the physical addresses for a given offset into the object instead of invoking the d_mmap() method in a device driver.

SVN rev 194766 on 2009-06-23 20:45:22Z by kib Implement global and per-uid accounting of the anonymous memory. Add rlimit RLIMIT_SWAP that limits the amount of swap that may be reserved for the uid. The accounting information (charge) is associated with either map entry, or vm object backing the entry, assuming the object is the first one in the shadow chain and entry does not require COW. Charge is moved from entry to object on allocation of the object, e.g. during the mmap, assuming the object is allocated, or on the first page fault on the entry. It moves back to the entry on forks due to COW setup. The per-entry granularity of accounting makes the charge process fair for processes that change uid during lifetime, and decrements charge for proper uid when region is unmapped. The interface of vm_pager_allocate(9) is extended by adding struct ucred *, that is used to charge appropriate uid when allocation if performed by kernel, e.g. md(4). Several syscalls, among them is fork(2), may now return ENOMEM when global or per-uid limits are enforced. In collaboration with: pho Reviewed by: alc Approved by: re (kensmith)

SVN rev 184652 on 2008-11-04 19:04:01Z by jhb Remove unnecessary locking around vn_fullpath(). The vnode lock for the vnode in question does not need to be held. All the data structures used during the name lookup are protected by the global name cache lock. Instead, the caller merely needs to ensure a reference is held on the vnode (such as vhold()) to keep it from being freed. In the case of procfs' <pid>/file entry, grab the process lock while we gain a new reference (via vhold()) on p_textvp to fully close races with execve(2). For the kern.proc.vmmap sysctl handler, use a shared vnode lock around the call to VOP_GETATTR() rather than an exclusive lock. MFC after: 1 month

vn_lock() is currently only used with the 'curthread' passed as argument. Remove this argument and pass curthread directly to underlying VOP_LOCK1() VFS method. This modify makes the code cleaner and in particular remove an annoying dependence helping next lockmgr() cleanup. KPI results, obviously, changed. Manpage and FreeBSD_version will be updated through further commits. As a side note, would be valuable to say that next commits will address a similar cleanup about VFS methods, in particular vop_lock1 and vop_unlock.

Jumbo-commit to enhance 32 bit application support on 64 bit kernels. This is good enough to be able to run a RELENG_4 gdb binary against a RELENG_4 application, along with various other tools (eg: 4.x gcore). We use this at work. ia32_reg.[ch]: handle the 32 bit register file format, used by ptrace, procfs and core dumps. procfs_*regs.c: vary the format of proc/XXX/*regs depending on the client and target application. procfs_map.c: Don't print a 64 bit value to 32 bit consumers, or their sscanf fails. They expect an unsigned long. imgact_elf.c: produce a valid 32 bit coredump for 32 bit apps. sys_process.c: handle 32 bit consumers debugging 32 bit targets. Note that 64 bit consumers can still debug 32 bit targets. IA64 has got stubs for ia32_reg.c. Known limitations: a 5.x/6.x gdb uses get/setcontext(), which isn't implemented in the 32/64 wrapper yet. We also make a tiny patch to gdb pacify it over conflicting formats of ld-elf.so.1. Approved by: re

With Alfred's permission, remove vm_mtx in favor of a fine-grained approach (this commit is just the first stage). Also add various GIANT_ macros to formalize the removal of Giant, making it easy to test in a more piecemeal fashion. These macros will allow us to test fine-grained locks to a degree before removing Giant, and also after, and to remove Giant in a piecemeal fashion via sysctl's on those subsystems which the authors believe can operate without Giant.

Introduce a global lock for the vm subsystem (vm_mtx). vm_mtx does not recurse and is required for most low level vm operations. faults can not be taken without holding Giant. Memory subsystems can now call the base page allocators safely. Almost all atomic ops were removed as they are covered under the vm mutex. Alpha and ia64 now need to catch up to i386's trap handlers. FFS and NFS have been tested, other filesystems will need minor changes (grabbing the vm lock when twiddling page properties). Reviewed (partially) by: jake, jhb

Make our v_usecount vnode reference count work identically to the original BSD code. The association between the vnode and the vm_object no longer includes reference counts. The major difference is that vm_object's are no longer freed gratuitiously from the vnode, and so once an object is created for the vnode, it will last as long as the vnode does. When a vnode object reference count is incremented, then the underlying vnode reference count is incremented also. The two "objects" are now more intimately related, and so the interactions are now much less complex. When vnodes are now normally placed onto the free queue with an object still attached. The rundown of the object happens at vnode rundown time, and happens with exactly the same filesystem semantics of the original VFS code. There is absolutely no need for vnode_pager_uncache and other travesties like that anymore. A side-effect of these changes is that SMP locking should be much simpler, the I/O copyin/copyout optimizations work, NFS should be more ponderable, and further work on layered filesystems should be less frustrating, because of the totally coherent management of the vnode objects and vnodes. Please be careful with your system while running this code, but I would greatly appreciate feedback as soon a reasonably possible.
