H A D | mii.h | diff 221407 Tue May 03 20:00:00 MDT 2011 marius - Remove attempts to implement setting of BMCR_LOOP/MIIF_NOLOOP (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.

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.

Now ppbus drivers setup their interrupt handler during attach and tear it down during detach like most other drivers. ppbus(4) only invokes the interrupt handler of the device that currently owns the bus (if any) when an interrupt occurs, however. Also, interrupt handlers in general now accept their softc pointers as their argument rather than the device_t. Another feature of the ppbus interrupt handlers is that they are called with the parent ppc device's lock already held.

On iicbb(4) allow the direct access of the OFW parent node by its children, so they can be directly attached to iicbb(4) node on the DTS without the need of describing the i2c bus. r261845: Allow the use of the OFW GPIO bus for ti_gpio and bcm2835_gpio. With this change the gpio children can be described as directly connected to the GPIO controller without the need of describing the OFW GPIO bus itself on the DTS file. With this commit the OFW GPIO bus is fully functional on BBB and RPi. GPIO controllers which want to use the OFW GPIO bus will need similar changes. r261846: Make the gpioled(4) work out of the box on BBB. Add gpioled(4) to BEAGLEBONE kernel and add the description of the four on-board leds of beaglebone-black to its DTS file. r262194: Remove an unnecessary header. r262522: Fix make depend for iicbus. r262559: Inspired by r262522, fix make depend. This fixes the build of gpio modules. |

That way we can correctly set the respective Fast-SCSI config bits instead of driving them out of specs. This includes adding the FAS100A and FAS236 variants to the NCR53C9x core code. We probably still subsume some chip variants as ESP200 while in fact they are another variant which however shouldn't really matter as this will only happen when these chips are driven at 25MHz or less which implies not being able to run Fast-SCSI.

In case of the variants that hang off of a DMA device this is a bit hackish as esp(4) then directly uses the softc of the respective parent to talk to the DMA engine.

This fixes at least two bugs: 1. The state of the Scroll Lock LED and the state of scroll mode could be out-of-sync. For instance, if one enables scroll mode on window #1 and switches to window #2, the LED would remain on, but the window wouldn't be in scroll mode. Similarily, when switching between a console and an X.Org session, the LED states could be inconsistent with the real state. 2. When exiting from an X.Org session, the user could be unable to type anything. The workaround was to switch to another console window and come back.

Sometimes, when scrolling or when changing the screen size (by changing the font or loading a KMS driver for instance), one could see the history cycling (old content appeared below latest lines). This is fixed. Now, when the resolution changes are more lines can be shown, the displayed area is adjusted so that, if the screen was filled with content before, it's filled with content after as well: more history is visible, instead of having blank lines below the previously visible content. r271872: vt(4): Remove superfluous word in comment Submitted by: brueffer@ r271899: Make gcc happy by initialising the variable only set in a couple of case statements without a default.

H A D | ncr53c9xreg.h | diff 226381 Sat Oct 15 09:32:32 MDT 2011 marius Merge from NetBSD: - Remove clause 3 and 4 from TNF licenses. - Fix memset usage. - Various cleanup. - Kill caddr_t. diff 182876 Mon Sep 08 20:21:05 MDT 2008 marius o Move the MODULE_DEPEND() for cam(4) from the esp_sbus.c front-end to the ncr53c9x.c core where it actually belongs so future front-ends don't need to add it. o Use the correct OFW property when looking for the initiator ID of the SBus device. o Don't specify an alignment when creating the parent DMA tag for SUNW,fas; their DMA engine doesn't require an alignment constraint and it's no inherited by the child DMA tags anyway (which probably is a bug though). o Drop the superfluous sc_maxsync and use sc_minsync instead. The former apparently was added due to a confusion with the maximum frequency used in cam(4), which basically corresponds to the inverse of minimum sync period. o Merge ncr53c9x.c from NetBSD: 1.116: NCRDMA_SETUP() should be called before NCR_SET_COUNT() and NCRCMD_DMA command in ncr53c9x_select(). 1.125: free allocated resources on detach. o Static'ize ncr53c9x_action(), ncr53c9x_init() and ncr53c9x_reset() as these are not required outside of ncr53c9x.c. o In ncr53c9x_attach() don't leak the device mutex in case attaching fails. o Register an asynchronous notification handler so in case cam(4) reports a lost device we can cancel outstanding commands and restore the default parameters for the target in question. o For FAS366 correctly support 16-bit target IDs and let it know that we use 32-bit transfers. o Overhaul the negotiation of transfer settings. This includes distinguishing between current and goal transfer settings of the target so we can renegotiate their goal settings when necessary and correcting the order in which tagged, wide and synchronous transfers are negotiated. o If we are requesting sense, force a renegotiation if we are currently using anything different from asynchronous at 8 bit as the target might have lost our transfer negotiations. o In case of an XPT_RESET_BUS just directly call ncr53c9x_init() instead of issuing a NCRCMD_RSTSCSI, which in turn will issue an interrupt that is treated as an unexpected SCSI bus reset by ncr53c9x_intr() and thus calls ncr53c9x_init(). Remove the now no longer used ncr53c9x_scsi_reset(). o Correct an off-by-one error when setting cpi->max_lun. o In replace printf(9) with device_printf(9) calls where appropriate and in ncr53c9x_action() remove some unnecessarily verbose messages. o In ncr53c9x_sched() use TAILQ_FOREACH() instead of reimplementing it and consolidate two tagging-related target info checks into one. o In ncr53c9x_done() set the CAM status to CAM_SCSI_STATUS_ERROR when appropriate, respect CAM_DIS_AUTOSENSE and teach it to return SCSI status information. o In ncr53c9x_dequeue() ensure the tags are cleared. o Use ulmin() instead of min() where appropriate. o In ncr53c9x_msgout() consistently use the reset label. o When we're interrupted during a data phase and the DMA engine is still active, don't panic but reset the core and the DMA engine as this should be sufficient. Also, the typical problem for triggering this was the lack of renegotiation when requesting sense. o Correctly handle DEVICE RESETs. o Adapt the locking of esp(4) to MPSAFE cam(4). This includes moving the calls of lsi64854_attach() to the bus front-ends so it can pass the esp(4) mutex to bus_dma_tag_create(9). o Change the LSI64854 driver to not create a DMA tag and map for the Ethernet channel as le(4) will handle these on its own as well as sync and unload the DMA maps for the SCSI and parallel port channel after a DMA transfer. o Cam(4)'ify some NetBSD-centric comments. o Use bus_{read,write}_*(9) instead of bus_space_{read,write}_*(9) and take advantage of rman_get_rid(9) in order to save some softc members.

Netmap gets its own hardware-assisted virtual interface and won't take over or disrupt the "normal" interface in any way. You can use both simultaneously. For kernels with DEV_NETMAP, cxgbe(4) carves out an ncxl<N> interface (note the 'n' prefix) in the hardware to accompany each cxl<N> interface. These two ifnet's per port share the same wire but really are separate interfaces in the hardware and software. Each gets its own L2 MAC addresses (unicast and multicast), MTU, checksum caps, etc. You should run netmap on the 'n' interfaces only, that's what they are for.

Single port receive is at 33Mpps but this is very much a work in progress. I expect it to be closer to 40Mpps once done.

It improves on sio(4) in the following areas: o Fully newbusified to allow for memory mapped I/O. This is a must for ia64 and sparc64, o Machine dependent code to take full advantage of machine and firm- ware specific ways to define serial consoles and/or debug ports. o Hardware abstraction layer to allow the driver to be used with various UARTs, such as the well-known ns8250 family of UARTs, the Siemens sab82532 or the Zilog Z8530. This is especially important for pc98 and sparc64 where it's common to have different UARTs, o The notion of system devices to unkludge low-level consoles and remote gdb ports and provides the mechanics necessary to support the keyboard on sparc64 (which is UART based). o The notion of a kernel interface so that a UART can be tied to something other than the well-known TTY interface. This is needed on sparc64 to present the user with a device and ioctl handling suitable for a keyboard, but also allows us to cleanly hide an UART when used as a debug port. Following is a list of features and bugs/flaws specific to the ns8250 family of UARTs as compared to their support in sio(4): o The uart(4) driver determines the FIFO size and automaticly takes advantages of larger FIFOs and/or additional features. Note that since I don't have sufficient access to 16[679]5x UARTs, hardware flow control has not been enabled. This is almost trivial to do, provided one can test. The downside of this is that broken UARTs are more likely to not work correctly with uart(4). The need for tunables or knobs may be large enough to warrant their creation. o The uart(4) driver does not share the same bumpy history as sio(4) and will therefore not provide the necessary hooks, tweaks, quirks or work-arounds to deal with once common hardware. To that extend, uart(4) supports a subset of the UARTs that sio(4) supports. The question before us is whether the subset is sufficient for current hardware. o There is no support for multiport UARTs in uart(4). The decision behind this is that uart(4) deals with one EIA RS232-C interface. Packaging of multiple interfaces in a single chip or on a single expansion board is beyond the scope of uart(4) and is now mostly left for puc(4) to deal with. Lack of hardware made it impossible to actually implement such a dependency other than is present for the dual channel SAB82532 and Z8350 SCCs. The current list of missing features is: o No configuration capabilities. A set of tunables and sysctls is being worked out. There are likely not going to be any or much compile-time knobs. Such configuration does not fit well with current hardware. o No support for the PPS API. This is partly dependent on the ability to configure uart(4) and partly dependent on having sufficient information to implement it properly.

The need for tunables or knobs may be large enough to warrant their creation. o The uart(4) driver does not share the same bumpy history as sio(4) and will therefore not provide the necessary hooks, tweaks, quirks or work-arounds to deal with once common hardware. To that extend, uart(4) supports a subset of the UARTs that sio(4) supports. The question before us is whether the subset is sufficient for current hardware. o There is no support for multiport UARTs in uart(4). The decision behind this is that uart(4) deals with one EIA RS232-C interface. Packaging of multiple interfaces in a single chip or on a single expansion board is beyond the scope of uart(4) and is now mostly left for puc(4) to deal with. Lack of hardware made it impossible to actually implement such a dependency other than is present for the dual channel SAB82532 and Z8350 SCCs. The current list of missing features is: o No configuration capabilities. A set of tunables and sysctls is being worked out. There are likely not going to be any or much compile-time knobs.

H A D | smbconf.c | diff 162234 Mon Sep 11 20:52:41 MDT 2006 jhb Minor overhaul of SMBus support: - Change smbus_callback() to pass a void * rather than caddr_t. - Change smbus_bread() to pass a pointer to the count and have it be an in/out parameter. The input is the size of the buffer (same as before), but on return it will contain the actual amount of data read back from the bus. Note that this value may be larger than the input value.

It is up to the caller to treat this as an error if desired. - Change the SMB_BREAD ioctl to write out the updated struct smbcmd which will contain the actual number of bytes read in the 'count' field. To preserve the previous ABI, the old ioctl value is mapped to SMB_OLD_BREAD which doesn't copy the updated smbcmd back out to userland. I doubt anyone actually used the old BREAD anyway as it was rediculous to do a bulk-read but not tell the using program how much data was actually read. - Make the smbus driver and devclass public in the smbus module and push all the DRIVER_MODULE()'s for attaching the smbus driver to various foosmb drivers out into the foosmb modules. This makes all the foosmb logic centralized and allows new foosmb modules to be self-contained w/o having to hack smbus.c everytime a new smbus driver is added. - Add a new SMB_EINVAL error bit and use it in place of EINVAL to return an error for bad arguments (such as invalid counts for bread and bwrite). - Map SMB bus error bits to EIO in smbus_error(). - Make the smbus driver call bus_generic_probe() and require child drivers such as smb(4) to create device_t's via identify routines. Previously, smbus just created one anonymous device during attach, and if you had multiple drivers that could attach it was just random chance as to which driver got to probe for the sole device_t first. - Add a mutex to the smbus(4) softc and use it in place of dummy splhigh() to protect the 'owner' field and perform necessary synchronization for smbus_request_bus() and smbus_release_bus(). - Change the bread() and bwrite() methods of alpm(4), amdpm(4), and viapm(4) to only perform a single transaction and not try to use a loop of multiple transactions for a large request. The framing and commands to use for a large transaction depend on the upper-layer protocol (such as SSIF for IPMI over SMBus) from what I can tell, and the smb(4) driver never allowed bulk read/writes of more than 32-bytes anyway. The other smb drivers only performed single transactions. - Fix buffer overflows in the bread() methods of ichsmb(4), alpm(4), amdpm(4), amdsmb(4), intpm(4), and nfsmb(4). - Use SMB_xxx errors in viapm(4). - Destroy ichsmb(4)'s mutex after bus_generic_detach() to avoid problems from child devices making smb upcalls that would use the mutex during their detach methods.

Netmap gets its own hardware-assisted virtual interface and won't take over or disrupt the "normal" interface in any way. You can use both simultaneously. For kernels with DEV_NETMAP, cxgbe(4) carves out an ncxl<N> interface (note the 'n' prefix) in the hardware to accompany each cxl<N> interface. These two ifnet's per port share the same wire but really are separate interfaces in the hardware and software. Each gets its own L2 MAC addresses (unicast and multicast), MTU, checksum caps, etc. You should run netmap on the 'n' interfaces only, that's what they are for. With this, pkt-gen is able to transmit > 45Mpps out of a single 40G port of a T580 card. 2 port tx is at ~56Mpps total (28M + 28M) as of now. Single port receive is at 33Mpps but this is very much a work in progress. I expect it to be closer to 40Mpps once done.

Sample configuration: Kernel: (you can use modules as well) device firewire device scbus device targ device sbp_targ After reboot: # mdconfig -a -t malloc -s 10m md0 # scsi_target 0:0:0 /dev/md0 (Assuming sbp_targ0 on scbus0) You should find the 10MB HDD on FreeBSD/MacOS X/WinXP or whatever connected to the target using FireWire. Manpage is not finished yet. 121186 Sat Oct 18 05:41:31 MDT 2003 simokawa Add SBP-II target mode driver. Though this is still incomplete and has some missing features such as exclusive login and event notification, it may be enough for someone who wants to play with it.

This device is used on some fiber optic gigE cards from SMC, D-Link and Addtron. Jumbograms and TCP/IP checksum offload on receive are supported. Hardware VLAN filtering is not, because it doesn't play well with our existing VLAN code. Also add manual page. There is a 4.x version of this driver available at http://www.freebsd.org/~wpaul/Level1/4.x if anyone feels adventurous and wants to test it. I still need to do performance testing and tuning with this device. (For my next trick, I will make the 3Com 3cR990 sit up and beg.) 77542 Thu May 31 21:44:26 MDT 2001 wpaul Add device driver support for the Level 1 LXT1001 NetCellerator gigabit ethernet controller chip.
