This driver also already includes all the code to support the `Oberon' Uranus to PCIe bridges found in the Fujitsu-Siemens based Mx000 machines but due to lack of access to such a system for testing, probing of these bridges is currently disabled. Unfortunately, the event queue mechanism of these bridges for MSIs/ MSI-Xs matches our current MD and MI interrupt frameworks like square pegs fit into round holes so for now we are generous and use one event queue per MSI, which limits us to 35 MSIs/MSI-Xs per Host-PCIe-bridge (we use one event queue for the PCIe error messages). This seems tolerable as long as most devices just use one MSI/MSI-X anyway. Adding knowledge about MSIs/MSI-Xs to the MD interrupt code should allow us to decouple the 1:1 mapping at the cost of no longer being able to bind MSIs/MSI-Xs to specific CPUs as we currently have no reliable way to quiesce a device during the transition of its MSIs/ MSI-Xs to another event queue. This would still require the problem of interrupt storms generated by devices which have no one-shot behavior or can't/don't mask interrupts while the filter/handler is executed (like the older PCIe NICs supported by bge(4)) to be solved though. | 15 January 2010, 21:45:55 UTC |

So add code to detect when things don't match and give the user choices about how to fix it. If we're using -P and something in the above check needs to be moved we need to have the directory there for it, so create it at the beginning and delete empty versions of it at the end. The case where something used to be a file or link and now is supposed to be a directory (e.g., /etc/security) is especially dangerous, so make failure to install a necessary directory in $DESTDIR a fatal error. MFC r200700: In the places where find is used that the user may see the results, first pipe it to sort so that order of processing will be deterministic and like things will be grouped together. MFC r200701: Fix an indentation issue, no functional changes MFC r200708: Fix a problem with how mergemaster handles the hard links for /.cshrc and /.profile. The problem is that install(1) will unlink the old file before it installs the new one, which means that in the best case we have to compare the changes for the old file twice. So, change the logic to first test to see if the link exists, then install the file. Then if the link was there and we're using -i, just create the link in /root and be done with it. Otherwise display the message to the user and give them the option. Because we are now sorting things before doing the comparison we can know conclusively that the files in / should be the sources, and the files in /root will be the targets, so adjust the paths accordingly. While I'm here, split a too-long error message into two lines and just return at the end of handling these files instead of setting the variable that says "do nothing" and then returning at the end of the function anyway. MFC r201291: Add some patches contributed by jhb: 1. Don't prompt the user for "-U but no db" error if we're using -a 2. Add an option to delete stale rc.d files automatically if the user has DELETE_STALE_RC_FILES in their rc file. Lack of command line option for this is not an oversight. 3. Add []'s around the terminal $ for the $FreeBSD$ test for -F For one bug raised by jhb I did a more thorough solution: There were a lot of things that "snuck in" between the end of the test for -r and the start of the comparison. One of them is the creation of the mtree db, as pointed out by jhb. Fix this problem more thoroughly by moving the end of the test down to where it should/used to be, right before the comparison. As a result, indent the interloping code to match. MFC r201292: Document the DELETE_STALE_RC_FILES option introduced in r201291. This is an "rc file only" option by design. While I'm here, update the comments in the example rc file to indicate which command line options they relate to, and correct the defaults for a couple of options. MFC r201293: It's not necessary to include both Op and Fl for command line options included in the text, so use only the latter. Clarify that using -U doesn't make sense in combination with -a MFC r201323: If we are using -p it does not make any sense to even create the MTREENEW file since it will never be used. MFC r201765: Update copyright date Update delete_temproot() to include the error message if it fails, and clean up the places where it's called.

Unlike TX interrupt, ST201 does not provide any mechanism to suppress RX interrupts. ste(4) can generate more than 70k RX interrupts under heavy RX traffics such that these excessive interrupts make system useless to process other useful things. Maybe this was the major reason why polling support code was introduced to ste(4). The STE_COUNTDOWN register provides a programmable counter that will generate an interrupt upon its expiration. We program STE_DMACTL register to use 3.2us clock rate to drive the counter register. Whenever ste(4) serves RX interrupt, the driver rearm the timer to expire after STE_IM_RX_TIMER_DEFAULT time and disables further generation of RX interrupts. This trick seems to work well and ste(4) generates less than 8k RX interrupts even under 64 bytes UDP torture test. Combined with TX interrupts, the total number of interrupts are less than 10k which looks reasonable on heavily loaded controller. The default RX interrupt moderation time is 150us. Users can change the value at any time with dev.ste.%d.int_rx_mod sysctl node. Setting it 0 effectively disables the RX interrupt moderation feature. Now we have both TX/RX interrupt moderation code so remove loop of interrupt handler which resulted in sub-optimal performance as well as more register accesses. r200955: Add suspend/resume support as well as basic WOL. While I'm here simplify SIOCSIFCAP handler. r200965: Update if_iqdrops in case of RX buffer allocation failure. r200966: ether_ifattach sets if_mtu, remove unnecessary code. r201767: Fix EEPROM access code to return data in host byte order.

The datasheet was wrong. r200913: We don't need to generate DMA complete interrupt for every transmitted frames. So request interrupt for every 16th frames. Due to the limitation of hardware we can't suppress the interrupt as driver should have to check TX status register. The TX status register can store up to 31 TX status so driver can't send more than 31 frames without reading TX status register. With this change controller would not generate TX completion interrupt for every frame, so reclaim transmitted frames in ste_tick(). | 14 January 2010, 22:18:55 UTC |
| 1d492e8 | Pyun YongHyeon | 14 January 2010, 22:04:32 UTC | MFC r200854,200856,200865,200873,200875,200877,200884 r200854: Add minimal dealy while ste(4) is waiting for the end of active DMA cycle. r200856: Introduce sc_flags member variable and use it to keep track of link state and PHY related information. Remove ste_link and ste_one_phy variable of softc as it's not used anymore. While I'm here add IFF_DRV_RUNNING check in ste_start_locked(). r200865: Reimplement miibus_statchg method. Don't rely on link state change interrupt. If we want to use link state change interrupt ste(4) should also implement auto-negotiation complete handler as well as various PHY access handling. Now link state change is handled by mii(4) polling so it will automatically update link state UP/DOWN events which in turn make ste(4) usable with lagg(4). r199559 added a private timer to drive watchdog and the timer also used to drive MAC statistics update. Because the MAC statistics update is called whenever statistics counter reaches near-full, it drove watchdog timer too fast such that it caused false watchdog timeouts under heavy TX traffic conditions. Fix the regression by separating ste_stats_update() from driving watchdog timer and introduce a new function ste_tick() that handles periodic job such as driving watchdog, MAC statistics update and link state check etc. While I'm here clear armed watchdog timer in ste_stop(). r200873: Instead of relying on hard resetting of controller to stop receiving incoming traffics, try harder to gracefully stop active DMA cycles and then stop MACs. This is the way what datasheet recommends and seems to work reliably. Resetting controller while active DMAs are in progress is bad thing as we can't predict how DMAs touche allocated TX/RX buffers. This change ensures controller stop state before attempting to release allocated TX/RX buffers. Also update MAC statistics which could have been updated during the wait time of MAC stop. While I'm here remove unnecessary controller resets in various location. ste(4) no longer relies on hard controller reset to stop controller and resetting controller also clears all configured settings which makes it hard to implement WOL in near future. Now resetting a controller is performed in ste_init_locked(). r200875: Prefer memory space register mapping over io space. If memory space mapping fails fall back to old io space mapping. While I'm here use PCIR_BAR macro. r200877: Prefer bus_write_{1,2,4}/bus_read_{1,2,4} to bus_space_write_{1,2,4}/bus_space_read_{1,2,4}. Remove unused ste_bhandle and ste_btag in softc. r200884: Reimplement Tx status error handler as recommended by datasheet. If ste(4) encounter TX underrun or excessive collisions the TX MAC of controller is stalled so driver should wake it up again. TX underrun requires increasing TX threshold value to minimize further TX underruns. Previously ste(4) used to reset controller to recover from TX underrun, excessive collision and reclaiming error. However datasheet says only TX underrun requires resetting entire controller. So implement ste_restart_tx() that restarts TX MAC and do not perform full reset except TX underrun case. Now ste(4) uses CSR_READ_2 instead of CSR_READ_1 to read STE_TX_STATUS register. This way ste(4) will also read frame id value and we can write the same value back to STE_TX_FRAMEID register instead of overwriting it to 0. The datasheet was wrong in write back of STE_TX_STATUS so add some comments why we do so. Also always invoke ste_txeoc() after ste_txeof() in ste_poll as without reading TX status register can stall TX MAC. | 14 January 2010, 22:04:32 UTC |
| b03c720 | Pyun YongHyeon | 14 January 2010, 21:54:20 UTC | MFC r200853: Add bus_dma(9) and endianness support to ste(4). o Sorted includes and added missing header files. o Added basic endianness support. In theory ste(4) should work on any architectures. o Remove the use of contigmalloc(9), contigfree(9) and vtophys(9). o Added 8 byte alignment limitation of TX/RX descriptor. o Added 1 byte alignment requirement for TX/RX buffers. o ste(4) controllers does not support DAC. Limit DMA address space to be within 32bit address. o Added spare DMA map to gracefully recover from DMA map failure. o Removed dead code for checking STE_RXSTAT_DMADONE bit. The bit was already checked in each iteration of loop so it can't be true. o Added second argument count to ste_rxeof(). It is used to limit number of iterations done in RX handler. ATM polling is the only consumer. o Removed ste_rxeoc() which was added to address RX stuck issue (cvs rev 1.66). Unlike TX descriptors, ST201 supports chaining descriptors to form a ring for RX descriptors. If RX descriptor chaining is not supported it's possible for controller to stop receiving incoming frames once controller pass the end of RX descriptor which in turn requires driver post new RX descriptors to receive more frames. For TX descriptors which does not support chaning, we exactly do manual chaining in driver by concatenating new descriptors to the end of previous TX chain. Maybe the workaround was borrowed from other drivers that does not support RX descriptor chaining, which is not valid for ST201 controllers. I still have no idea how this address RX stuck issue and I can't reproduce the RX stuck issue on DFE-550TX controller. o Removed hw.ste_rxsyncs sysctl as the workaround was removed. o TX/RX side bus_dmamap_load_mbuf_sg(9) support. o Reimplemented optimized ste_encap(). o Simplified TX logic of ste_start_locked(). o Added comments for TFD/RFD requirements. o Increased number of RX descriptors to 128 from 64. 128 gave much better performance than 64 under high network loads. | 14 January 2010, 21:54:20 UTC |

TX/RX interrupt mitigation is controlled by VGE_TXSUPPTHR and VGE_RXSUPPTHR register. These registers suppress generation of interrupts until the programmed frames counter equals to the registers. VT61xx also supports interrupt hold off timer register. If this interrupt hold off timer is active all interrupts would be disabled until the timer reaches to 0. The timer value is reloaded whenever VGE_ISR register written. The timer resolution is about 20us. Previously vge(4) used single shot timer to reduce Tx completion interrupts. This required VGE_CRS1 register access in Tx start/completion handler to rearm new timeout value and it did not show satisfactory result(more than 50k interrupts under load). Rx interrupts was not moderated at all such that vge(4) used to generate too many interrupts which in turn made polling(4) better approach under high network load. This change activates all interrupt moderation mechanism and initial values were tuned to generate interrupt less than 8k per second. That number of interrupts wouldn't add additional packet latencies compared to polling(4).
