Device Polling code for -current. Non-SMP, i386-only, no polling in the idle loop at the moment. To use this code you must compile a kernel with options DEVICE_POLLING and at runtime enable polling with sysctl kern.polling.enable=1 The percentage of CPU reserved to userland can be set with sysctl kern.polling.user_frac=NN (default is 50) while the remainder is used by polling device drivers and netisr's. These are the only two variables that you should need to touch. There are a few more parameters in kern.polling but the default values are adequate for all purposes. See the code in kern_poll.c for more details on them. Polling in the idle loop will be implemented shortly by introducing a kernel thread which does the job. Until then, the amount of CPU dedicated to polling will never exceed (100-user_frac). The equivalent (actually, better) code for -stable is at http://info.iet.unipi.it/~luigi/polling/ and also supports polling in the idle loop. NOTE to Alpha developers: There is really nothing in this code that is i386-specific. If you move the 2 lines supporting the new option from sys/conf/{files,options}.i386 to sys/conf/{files,options} I am pretty sure that this should work on the Alpha as well, just that I do not have a suitable test box to try it. If someone feels like trying it, I would appreciate it. NOTE to other developers: sure some things could be done better, and as always I am open to constructive criticism, which a few of you have already given and I greatly appreciated. However, before proposing radical architectural changes, please take some time to possibly try out this code, or at the very least read the comments in kern_poll.c, especially re. the reason why I am using a soft netisr and cannot (I believe) replace it with a simple timeout.

Split common TX/RX descriptor DMA tag to TX and RX DMA tags respectively and fix all bus_dma(9) issues seen when bounce buffers are used. o Setup frame handling had no bus_dmamap_sync(9) which prevented driver from configuring RX filter.

This change will minimize the size of bounce buffers that would be used in each TX/RX path. Previously driver had to copy both TX/RX lists when bounce buffer is active. o 21143 data sheet says descriptor list requires 4 bytes alignment. Remove PAGE_SIZE alignment restriction and use sizeof(struct dc_dec). o Setup frame requires 4 bytes alignment.

Previously driver allowed to copy received frame with m_devget(9) after passing the descriptor ownership to controller. This can lead to passing wrong frame to upper stack. o Introduce dc_discard_rxbuf() which will discard received frame and reuse loaded DMA map and RX mbuf. o Correct several wrong bus_dmamap_sync(9) usage in dc_rxeof and dc_txeof. The TX/RX descriptor lists are updated by both driver and HW so READ/WRITE semantics should be used. o If driver failed to allocate new RX buffer, update if_iqdrops counter instead of if_ierrors since driver received the frame without errors. o Make sure to unload loaded setup frame DMA map in dc_txeof and clear the mark of setup frame of the TX descriptor in dc_txeof(). o Add check for possible TX descriptor overruns in dc_encap() and move check for free buffer to caller, dc_start_locked(). o Swap the loaded DMA map and the last DMA map for multi-segmented frames. Since dc_txeof() assumes the last descriptor of the frame has the DMA map, driver should swap the first and the last DMA map in dc_encap().

Split common TX/RX descriptor DMA tag to TX and RX DMA tags respectively and fix all bus_dma(9) issues seen when bounce buffers are used. o Setup frame handling had no bus_dmamap_sync(9) which prevented driver from configuring RX filter. Add missing bus_dmamap_sync(9) in both dc_setfilt_21143()/dc_setfilt_xircom() and dc_txeof(). o Use bus_addr_t for DMA segment instead of using u_int32_t. o Introduce dc_dma_alloc()/dc_dma_free() functions to allocate/free DMA'able memory. o Create two DMA descriptor list for each TX/RX lists. This change will minimize the size of bounce buffers that would be used in each TX/RX path. Previously driver had to copy both TX/RX lists when bounce buffer is active. o 21143 data sheet says descriptor list requires 4 bytes alignment. Remove PAGE_SIZE alignment restriction and use sizeof(struct dc_dec). o Setup frame requires 4 bytes alignment. Remove PAGE_SIZE alignment restriction and use sizeof(struct dc_dec). o Add missing DMA map unload for both setup frame and TX/RX descriptor list. o Overhaul RX handling logic such that make driver always allocate new RX buffer with dc_newbuf(). Previously driver allowed to copy received frame with m_devget(9) after passing the descriptor ownership to controller. This can lead to passing wrong frame to upper stack. o Introduce dc_discard_rxbuf() which will discard received frame and reuse loaded DMA map and RX mbuf. o Correct several wrong bus_dmamap_sync(9) usage in dc_rxeof and dc_txeof. The TX/RX descriptor lists are updated by both driver and HW so READ/WRITE semantics should be used. o If driver failed to allocate new RX buffer, update if_iqdrops counter instead of if_ierrors since driver received the frame without errors. o Make sure to unload loaded setup frame DMA map in dc_txeof and clear the mark of setup frame of the TX descriptor in dc_txeof(). o Add check for possible TX descriptor overruns in dc_encap() and move check for free buffer to caller, dc_start_locked(). o Swap the loaded DMA map and the last DMA map for multi-segmented frames. Since dc_txeof() assumes the last descriptor of the frame has the DMA map, driver should swap the first and the last DMA map in dc_encap(). Previously driver tried to unload not-yet-loaded DMA map such that the loaded DMA map was not unloaded at all for multi-segmented frames. o Rewrite DC_RXDESC/DC_TXDESC macro to simpler one. o Remove definition of ETHER_ALIGN, it's already defined in ethernet.h. With this changes, dc(4) works with bounce buffers and it shall also fix issues which might have shown in PAE environments. Tested by: marius

Device Polling code for -current. Non-SMP, i386-only, no polling in the idle loop at the moment. To use this code you must compile a kernel with options DEVICE_POLLING and at runtime enable polling with sysctl kern.polling.enable=1 The percentage of CPU reserved to userland can be set with sysctl kern.polling.user_frac=NN (default is 50) while the remainder is used by polling device drivers and netisr's. These are the only two variables that you should need to touch. There are a few more parameters in kern.polling but the default values are adequate for all purposes. See the code in kern_poll.c for more details on them. Polling in the idle loop will be implemented shortly by introducing a kernel thread which does the job. Until then, the amount of CPU dedicated to polling will never exceed (100-user_frac). The equivalent (actually, better) code for -stable is at http://info.iet.unipi.it/~luigi/polling/ and also supports polling in the idle loop. NOTE to Alpha developers: There is really nothing in this code that is i386-specific. If you move the 2 lines supporting the new option from sys/conf/{files,options}.i386 to sys/conf/{files,options} I am pretty sure that this should work on the Alpha as well, just that I do not have a suitable test box to try it. If someone feels like trying it, I would appreciate it. NOTE to other developers: sure some things could be done better, and as always I am open to constructive criticism, which a few of you have already given and I greatly appreciated. However, before proposing radical architectural changes, please take some time to possibly try out this code, or at the very least read the comments in kern_poll.c, especially re. the reason why I am using a soft netisr and cannot (I believe) replace it with a simple timeout. Quick description of files touched by this commit: sys/conf/files.i386 new file kern/kern_poll.c sys/conf/options.i386 new option sys/i386/i386/trap.c poll in trap (disabled by default) sys/kern/kern_clock.c initialization and hardclock hooks. sys/kern/kern_intr.c minor swi_net changes sys/kern/kern_poll.c the bulk of the code. sys/net/if.h new flag sys/net/if_var.h declaration for functions used in device drivers. sys/net/netisr.h NETISR_POLL sys/dev/fxp/if_fxp.c sys/dev/fxp/if_fxpvar.h sys/pci/if_dc.c sys/pci/if_dcreg.h sys/pci/if_sis.c sys/pci/if_sisreg.h device driver modifications

Change and clean the mutex lock interface. mtx_enter(lock, type) becomes: mtx_lock(lock) for sleep locks (MTX_DEF-initialized locks) mtx_lock_spin(lock) for spin locks (MTX_SPIN-initialized) similarily, for releasing a lock, we now have: mtx_unlock(lock) for MTX_DEF and mtx_unlock_spin(lock) for MTX_SPIN. We change the caller interface for the two different types of locks because the semantics are entirely different for each case, and this makes it explicitly clear and, at the same time, it rids us of the extra `type' argument. The enter->lock and exit->unlock change has been made with the idea that we're "locking data" and not "entering locked code" in mind. Further, remove all additional "flags" previously passed to the lock acquire/release routines with the exception of two: MTX_QUIET and MTX_NOSWITCH The functionality of these flags is preserved and they can be passed to the lock/unlock routines by calling the corresponding wrappers: mtx_{lock, unlock}_flags(lock, flag(s)) and mtx_{lock, unlock}_spin_flags(lock, flag(s)) for MTX_DEF and MTX_SPIN locks, respectively. Re-inline some lock acq/rel code; in the sleep lock case, we only inline the _obtain_lock()s in order to ensure that the inlined code fits into a cache line. In the spin lock case, we inline recursion and actually only perform a function call if we need to spin. This change has been made with the idea that we generally tend to avoid spin locks and that also the spin locks that we do have and are heavily used (i.e. sched_lock) do recurse, and therefore in an effort to reduce function call overhead for some architectures (such as alpha), we inline recursion for this case. Create a new malloc type for the witness code and retire from using the M_DEV type. The new type is called M_WITNESS and is only declared if WITNESS is enabled. Begin cleaning up some machdep/mutex.h code - specifically updated the "optimized" inlined code in alpha/mutex.h and wrote MTX_LOCK_SPIN and MTX_UNLOCK_SPIN asm macros for the i386/mutex.h as we presently need those. Finally, caught up to the interface changes in all sys code. Contributors: jake, jhb, jasone (in no particular order)
