* Mark more nodes as CTLFLAG_MPSAFE or CTLFLAG_NEEDGIANT (17 of many)Pawel Biernacki2020-02-261-9/+10
| | | | | | | | | | | | | | | | | | | r357614 added CTLFLAG_NEEDGIANT to make it easier to find nodes that are still not MPSAFE (or already are but aren’t properly marked). Use it in preparation for a general review of all nodes. This is non-functional change that adds annotations to SYSCTL_NODE and SYSCTL_PROC nodes using one of the soon-to-be-required flags. Mark all obvious cases as MPSAFE. All entries that haven't been marked as MPSAFE before are by default marked as NEEDGIANT Approved by: kib (mentor, blanket) Commented by: kib, gallatin, melifaro Differential Revision: https://reviews.freebsd.org/D23718 Notes: svn path=/head/; revision=358333

* Announce flow control ability to PHY driver and enable RX flowPyun YongHyeon2011-12-092-4/+27
| | | | | | | | | | | | | | | | | | | control. Controller does not automatically generate pause frames based on number of available RX buffers so it's very hard to know when driver should generate XON frame in time. The only mechanism driver can detect low number of RX buffer condition is ET_INTR_RXRING0_LOW or ET_INTR_RXRING1_LOW interrupt. This interrupt is generated whenever controller notices the number of available RX buffers are lower than pre-programmed value( ET_RX_RING0_MINCNT and ET_RX_RING1_MINCNT register). This scheme does not provide a way to detect when controller sees enough number of RX buffers again such that efficient generation of XON/XOFF frame is not easy.

Add RX/TX DMA error to interrupt handler and do full controller reset if driver happen to encounter these errors. There is no way to recover from these DMA errors without controller reset. Rename local variable name intrs with status to enhance readability. While I'm here, rename ET_INTR_TXEOF and ET_INTR_RXEOF to ET_INTR_TXDMA and ET_INTR_RXDMA respectively. These interrupts indicate that a frame is successfully DMAed to controller's internal FIFO and they have nothing to do with EOF(end of frame). Driver does not need to wait actual end of TX/RX of a frame(e.g. no need to wait the end signal of TX which is generated when a frame in TX FIFO is emptied by MAC).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | o Do not report link status if driver is not running. o TX/RX MAC configuration should be done with resolved speed, duplex and flow control after establishing a link so it can't be done in driver initialization routine. Move the configuration to miibus_statchg callback which will be called whenever any link state change is detected. At this moment, flow-control is not enabled yet mainly because I was not able to set correct flow control parameters to generate TX pause frames. o Now TX/RX MAC is enabled only when a valid link is detected. Rearragnge hardware initialization routine a bit to leave enabling MAC to miibus_statchg callback. In order to that, TX/RX DMA engine is enabled in et_init_locked(). o Introduce ET_FLAG_LINK flag to track current link state. o Introduce ET_FLAG_FASTETHER flag to mark whether controller is fast ethernet. This flag is checked in miibus_statchg callback to know whether PHY established a valid link. o In et_stop(), TX/RX MAC is explicitly disabled instead of relying on et_reset(). And move et_reset() from et_stop() to controller initialization. Controler reset is not required here and it would also clear critial registers(i.e station address, RX filter configuration, WOL etc) that are required to make WOL work. o Switching to current media is done in et_init_locked() after setting IFF_DRV_RUNNING flag. This should ensure reliable auto-negotiation/manual link establishment. o In et_start_locked(), check whether driver got a valid link before trying to send frames. o Remove checking a link in et_tick() as this is done by miibus_statchg callback.

* Controller does not require TX start command for every frame. SoPyun YongHyeon2011-12-072-10/+30
| | | | | | | | | | | | | | | | | | | | | | | | send a single TX command after setting up all TX frames. This removes unnecessary register accesses and bus_dmamap_sync(9) calls. et(4) uses TX interrupt moderation so it's possible to have TX buffers that were already transmitted but waiting for TX completion interrupt. If the number of available TX descriptor is less then 1/3 of total TX descriptor, try reclaiming first to get enough free TX descriptors before setting up TX descriptors. After r228325, et_txeof() no longer tries to send frames after reclaiming TX buffers. That change was made to give more chance to transmit frames in main interrupt handler since we can still send frames in interrupt handler with RX interrupt. So right before exiting interrupt hander, after enabling interrupt, try to send more frames. This gives slightly better performance numbers. While I'm here reduce number of spare TX descriptors from 8 to 4. Controller does not require reserved TX descriptors, it was just to reduce TX overhead. After r228325, driver has much lower TX overhead so it does not make sense to reserve 8 TX descriptors. Notes: svn path=/head/; revision=228326

Previous code tried to minimize code duplication but this came from incorrect use of common DMA tag. Driver may be still use a common RX allocation handler with additional structure changes but I don't see much point to do that it would make it hard to understand the code. o Remove DragonflyBSD specific constant EVL_ENCAPLEN, use ETHER_VLAN_ENCAP_LEN instead. o Add bunch of new RX status definition. It seems controller supports RX checksum offloading but I was not able to make the feature work yet. Currently driver checks whether recevied frame is good one or not. o Avoid a typedef ending in '_t' as style(9) says. o Controller has no restriction on DMA address space, so there is no reason to limit the DMA address to 32bit. Descriptor rings, status blocks and TX/RX buffers now use full 64bit DMA addressing. o Allocate DMA memory shared between host and controller as coherent. o Create 3 separate DMA tags to be used as TX, mini RX ring and stanard RX ring. Previously it created a single DMA tag and it was used to all three rings. o et(4) does not support jumbo frame at this moment and I still don't quite understand how jumbo frame works on this controller so use two RX rings to handle small sized frame and normal sized frame respectively. The mini RX ring will be used to receive frames that are less than or equal to 127 bytes. The second RX ring is used to receive frames that are not handled by the first RX ring. If jumbo frame support is implemented, driver may have to choose better RX scheme by letting the second RX ring handle jumbo frames. This scheme will mimic Broadcom's efficient jumbo frame handling feature. However RAM buffer size(16KB) of the controller is too small to hold 2 jumbo frames, if 9KB jumbo frame is used, I'm not sure how good performance would it have. o In et_rxeof(), make sure to check whether controller received good frame or not. Passing corrupted frame to upper layer is bad idea. o If driver receives a bad frame or driver fails to allocate RX buffer due to resource shortage condition, reuse previously loaded DMA map for RX buffer instead of unloading/loading RX buffer again. o et_init_tx_ring() never fails so change return type to void. o In watchdog handler, show TX DMA write back status of errored frame which could be used as a clue to debug watchdog timeout. o Add missing bus_dmamap_sync() in various places such that et(4) should work with bounce buffers(e.g. PAE). o TX side bus_dmamap_load_mbuf_sg(9) support. o RX side bus_dmamap_load_mbuf_sg(9) support. o Controller has no DMA alignment limit in RX buffer so use m_adj(9) in RX buffer allocation to make IP header align on 2 bytes boundary. Otherwise it would trigger unaligned access error in upper layer on strict alignment architectures. One of down side of controller is it provides limited set of RX buffer length like most Intel controllers. This is not problem at this moment because driver does not support jumbo frame yet but it may require alignment fixup code to support jumbo frame on strict alignment architectures. o In et_txeof(), don't zero TX descriptors for transmitted frames. TX descriptors don't need write access after transmission. Driver sets IFF_DRV_OACTIVE when the number of available TX descriptors are less than or equal to ET_NSEG_SPARE. Make sure to clear IFF_DRV_OACTIVE only when the number of available TX descriptor is greater than ET_NSEG_SPARE. Notes: svn path=/head/; revision=228325

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (reporting IFM_LOOP based on BMCR_LOOP is left in place though as it might provide useful for debugging). For most mii(4) drivers it was unclear whether the PHYs driven by them actually support loopback or not. Moreover, typically loopback mode also needs to be activated on the MAC, which none of the Ethernet drivers using mii(4) implements. Given that loopback media has no real use (and obviously hardly had a chance to actually work) besides for driver development (which just loopback mode should be sufficient for though, i.e one doesn't necessary need support for loopback media) support for it is just dropped as both NetBSD and OpenBSD already did quite some time ago. - Let mii_phy_add_media() also announce the support of IFM_NONE. - Restructure the PHY entry points to use a structure of entry points instead of discrete function pointers, and extend this to include a "reset" entry point. Make sure any PHY-specific reset routine is always used, and provide one for lxtphy(4) which disables MII interrupts (as is done for a few other PHYs we have drivers for). This includes changing NIC drivers which previously just called the generic mii_phy_reset() to now actually call the PHY-specific reset routine, which might be crucial in some cases. While at it, the redundant checks in these NIC drivers for mii->mii_instance not being zero before calling the reset routines were removed because as soon as one PHY driver attaches mii->mii_instance is incremented and we hardly can end up in their media change callbacks etc if no PHY driver has attached as mii_attach() would have failed in that case and not attach a miibus(4) instance. Consequently, NIC drivers now no longer should call mii_phy_reset() directly, so it was removed from EXPORT_SYMS. - Add a mii_phy_dev_attach() as a companion helper to mii_phy_dev_probe(). The purpose of that function is to perform the common steps to attach a PHY driver instance and to hook it up to the miibus(4) instance and to optionally also handle the probing, addition and initialization of the supported media. So all a PHY driver without any special requirements has to do in its bus attach method is to call mii_phy_dev_attach() along with PHY-specific MIIF_* flags, a pointer to its PHY functions and the add_media set to one. All PHY drivers were updated to take advantage of mii_phy_dev_attach() as appropriate. Along with these changes the capability mask was added to the mii_softc structure so PHY drivers taking advantage of mii_phy_dev_attach() but still handling media on their own do not need to fiddle with the MII attach arguments anyway. - Keep track of the PHY offset in the mii_softc structure. This is done for compatibility with NetBSD/OpenBSD. - Keep track of the PHY's OUI, model and revision in the mii_softc structure. Several PHY drivers require this information also after attaching and previously had to wrap their own softc around mii_softc. NetBSD/OpenBSD also keep track of the model and revision on their mii_softc structure. All PHY drivers were updated to take advantage as appropriate. - Convert the mebers of the MII data structure to unsigned where appropriate. This is partly inspired by NetBSD/OpenBSD. - According to IEEE 802.3-2002 the bits actually have to be reversed when mapping an OUI to the MII ID registers. All PHY drivers and miidevs where changed as necessary. Actually this now again allows to largely share miidevs with NetBSD, which fixed this problem already 9 years ago. Consequently miidevs was synced as far as possible. - Add MIIF_NOMANPAUSE and mii_phy_flowstatus() calls to drivers that weren't explicitly converted to support flow control before. It's unclear whether flow control actually works with these but typically it should and their net behavior should be more correct with these changes in place than without if the MAC driver sets MIIF_DOPAUSE.
