* Mega busdma API commit.Scott Long2003-07-011-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | Add two new arguments to bus_dma_tag_create(): lockfunc and lockfuncarg. Lockfunc allows a driver to provide a function for managing its locking semantics while using busdma. At the moment, this is used for the asynchronous busdma_swi and callback mechanism. Two lockfunc implementations are provided: busdma_lock_mutex() performs standard mutex operations on the mutex that is specified from lockfuncarg. dftl_lock() is a panic implementation and is defaulted to when NULL, NULL are passed to bus_dma_tag_create(). The only time that NULL, NULL should ever be used is when the driver ensures that bus_dmamap_load() will not be deferred. Drivers that do not provide their own locking can pass busdma_lock_mutex,&Giant args in order to preserve the former behaviour. sparc64 and powerpc do not provide real busdma_swi functions, so this is largely a noop on those platforms. The busdma_swi on is64 is not properly locked yet, so warnings will be emitted on this platform when busdma callback deferrals happen. If anyone gets panics or warnings from dflt_lock() being called, please let me know right away. Reviewed by: tmm, gibbs Notes: svn path=/head/; revision=117126

| | | | | | | | | | | | While a string is readable without a tool, an array is easier to process for a monitoring application. This also prevents the extra hoops we need with sbufs and locking.

| | | | | | | | | | | | | | | | | | | | | | | following changes have been done: - stylify. The original code was too hard to read. - get rid of a number of compilation options (Adaptec-only, Eni-only, no-DMA). - more debugging features. - locking. This is not correct yet in the absence of interface layer locking, but is correct enough to not to cause lock order reversals. - remove RAW mode. There are no users of this in the tree and I doubt that there are any. - remove NetBSD compatibility code. There was no way to keep NetBSD non-busdma and FreeBSD busdma code together. - if_en now buildable as a module.

* Correct mbuf packet header propagation. Previously, packet headersSam Leffler2002-12-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | were sometimes propagated using M_COPY_PKTHDR which actually did something between a "move" and a "copy" operation. This is replaced by M_MOVE_PKTHDR (which copies the pkthdr contents and "removes" it from the source mbuf) and m_dup_pkthdr which copies the packet header contents including any m_tag chain. This corrects numerous problems whereby mbuf tags could be lost during packet manipulations. These changes also introduce arguments to m_tag_copy and m_tag_copy_chain to specify if the tag copy work should potentially block. This introduces an incompatibility with openbsd which we may want to revisit. Note that move/dup of packet headers does not handle target mbufs that have a cluster bound to them. We may want to support this; for now we watch for it with an assert. Finally, M_COPYFLAGS was updated to include M_FIRSTFRAG|M_LASTFRAG.

| | | | | | | | | | | | | | | | | before adding/removing packets from the queue. Also, the if_obytes and if_omcasts fields should only be manipulated under protection of the mutex. IF_ENQUEUE, IF_PREPEND, and IF_DEQUEUE perform all necessary locking on the queue. An IF_LOCK macro is provided, as well as the old (mutex-less) versions of the macros in the form _IF_ENQUEUE, _IF_QFULL, for code which needs them, but their use is discouraged. Two new macros are introduced: IF_DRAIN() to drain a queue, and IF_HANDOFF, which takes care of locking/enqueue, and also statistics updating/start if necessary.

* Replace the mbuf external reference counting code with somethingDavid Malone2000-08-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | that should be better. The old code counted references to mbuf clusters by using the offset of the cluster from the start of memory allocated for mbufs and clusters as an index into an array of chars, which did the reference counting. If the external storage was not a cluster then reference counting had to be done by the code using that external storage. NetBSD's system of linked lists of mbufs was cosidered, but Alfred felt it would have locking issues when the kernel was made more SMP friendly. The system implimented uses a pool of unions to track external storage. The union contains an int for counting the references and a pointer for forming a free list. The reference counts are incremented and decremented atomically and so should be SMP friendly. This system can track reference counts for any sort of external storage. Access to the reference counting stuff is now through macros defined in mbuf.h, so it should be easier to make changes to the system in the future. The possibility of storing the reference count in one of the referencing mbufs was considered, but was rejected 'cos it would often leave extra mbufs allocated. Storing the reference count in the cluster was also considered, but because the external storage may not be a cluster this isn't an option. The size of the pool of reference counters is available in the stats provided by "netstat -m".
