1.43	14-May-2006	elad	integrate kauth.
1.42	29-Mar-2006	thorpej	Use device_private().
1.41	11-Dec-2005	christos	branches: 1.41.4; 1.41.6; 1.41.8; 1.41.10; 1.41.12; make this compile again (from Johnny Billquist)
1.40	11-Dec-2005	christos	merge ktrace-lwp.
1.39	06-Sep-2005	kleink	Change the driver open function's conditional for overriding exclusive tty use from checking the proc's uid to suser(9), and account for the use of privileges. Noted by David Holland in PR kern/31126. Also change this to use the proc argument instead of curproc.
1.38	26-Feb-2005	simonb	branches: 1.38.4; White space nits.
1.37	04-Feb-2005	perry	de-__P
1.36	12-May-2004	wiz	branches: 1.36.4; 1.36.6; Remove UCB ad clause in Hugh Graham's license. Ok'd by Hugh Graham and board.
1.35	25-Apr-2004	matt	Constify the speedtab arrays
1.34	07-Aug-2003	agc	Move UCB-licensed code from 4-clause to 3-clause licence. Patches provided by Joel Baker in PR 22364, verified by myself.
1.33	06-Apr-2003	ragge	branches: 1.33.2; A bunch of fixes to make the DHU driver much more efficient, from Hugh Graham (hugh@openbsd.org).
1.32	23-Oct-2002	jdolecek	merge kqueue branch into -current kqueue provides a stateful and efficient event notification framework currently supported events include socket, file, directory, fifo, pipe, tty and device changes, and monitoring of processes and signals kqueue is supported by all writable filesystems in NetBSD tree (with exception of Coda) and all device drivers supporting poll(2) based on work done by Jonathan Lemon for FreeBSD initial NetBSD port done by Luke Mewburn and Jason Thorpe
1.31	02-Oct-2002	thorpej	Add trailing ; to CFATTACH_DECL.
1.30	30-Sep-2002	thorpej	Use CFATTACH_DECL().
1.29	27-Sep-2002	thorpej	Declare all cfattach structures const.
1.28	25-Sep-2002	thorpej	Don't include <sys/map.h>.
1.27	06-Sep-2002	gehenna	Merge the gehenna-devsw branch into the trunk. This merge changes the device switch tables from static array to dynamically generated by config(8). - All device switches is defined as a constant structure in device drivers. - The new grammer ``device-major'' is introduced to ``files''. device-major <prefix> char <num> [block <num>] [<rules>] - All device major numbers must be listed up in port dependent majors.<arch> by using this grammer. - Added the new naming convention. The name of the device switch must be <prefix>_[bc]devsw for auto-generation of device switch tables. - The backward compatibility of loading block/character device switch by LKM framework is broken. This is necessary to convert from block/character device major to device name in runtime and vice versa. - The restriction to assign device major by LKM is completely removed. We don't need to reserve LKM entries for dynamic loading of device switch. - In compile time, device major numbers list is packed into the kernel and the LKM framework will refer it to assign device major number dynamically.
1.26	17-Mar-2002	atatat	branches: 1.26.4; Convert ioctl code to use EPASSTHROUGH instead of -1 or ENOTTY for indicating an unhandled "command". ERESTART is -1, which can lead to confusion. ERESTART has been moved to -3 and EPASSTHROUGH has been placed at -4. No ioctl code should now return -1 anywhere. The ioctl() system call is now properly restartable.
1.25	13-Nov-2001	lukem	add RCSIDs
1.24	26-May-2001	ragge	branches: 1.24.2; 1.24.4; Use cdev_decl() instead of local prototyping.
1.23	02-May-2001	scw	Add `l_poll' to `struct linesw' and provide an xxxpoll() entry point in each tty driver to indirect through it. This allows tty line-disciplines to handle poll(2) system calls.
1.22	31-Mar-2001	enami	Remove unnecessary test of tp->t_linesw against NULL; they are results of confusion while correcting compilation error after t_line is replaced with t_linesw.
1.21	02-Nov-2000	eeh	branches: 1.21.2; Adapt to the new line discipline scheme.
1.20	05-Jun-2000	matt	Adjust to new evcnt stuff.
1.19	04-Jun-2000	matt	More event counter stuff. Plus a little cruft cleanup while doing it.
1.18	30-Mar-2000	augustss	branches: 1.18.2; Remove register declarations.
1.17	24-Jan-2000	matt	Revamp the VAX interrupt handling code. Make it compatible with all the other ports. Clean up some things.
1.16	06-Jun-1999	ragge	branches: 1.16.2; 1.16.4; Fix map register/DMA wait queues. Still to do: BDP handling. Currently missing. Ubareset's won't work at all.
1.15	28-May-1999	ragge	The DHU code changed to use bus_space. XXX - still need to use bus_dma.
1.14	28-May-1999	ragge	Copied from ../../arch/vax/uba/dhu.c,v
1.13	19-Jan-1999	ragge	Allocate (almost) all interrupt vectors dynamically. Simplifies much work when adding support for new machines and devices.
1.12	13-Apr-1998	ragge	t_wopen fixes.
1.11	24-Jan-1998	ragge	Remove __BROKEN_INDIRECT_CONFIG and change all drivers to use config_search instead.
1.10	12-Jan-1998	thorpej	Update for changes to config.
1.9	11-Jan-1997	ragge	Update due to changes to uba/mscp functions.
1.8	13-Oct-1996	christos	backout previous kprintf change
1.7	11-Oct-1996	christos	printf -> kprintf, sprintf -> ksprintf
1.6	02-Sep-1996	mycroft	tty stop functions really should return void, not int, and certainly not both.
1.5	19-May-1996	ragge	Update from Ken Wellsch.
1.4	08-Apr-1996	ragge	Added prototypes to everything. Made all files compile with -Wall.
1.3	18-Mar-1996	ragge	Ubareset are now possible, devices that wants it now set it up during autoconfig. ifubareset (if_reset) no longer used, actually it's just a normal ubareset and is now handled like that.
1.2	17-Mar-1996	ragge	Update from Ken Wellsch: The DHU driver can now handle DMA transfers.
1.1	02-Mar-1996	ragge	Unibus/Q22 bus device driver for DHU-11 serial card. Written by Ken Wellsch. (kcwellsc@math.uwaterloo.ca)
1.16.4.3	21-Apr-2001	bouyer	Sync with HEAD
1.16.4.2	22-Nov-2000	bouyer	Sync with HEAD.
1.16.4.1	20-Nov-2000	bouyer	Update thorpej_scsipi to -current as of a month ago A i386 GENERIC kernel compiles without the siop, ahc and bha drivers (will be updated later). i386 IDE/ATAPI and ncr work, as well as sparc/esp_sbus. alpha should work as well (untested yet). siop, ahc and bha will be updated once I've updated the branch to current -current, as well as machine-dependant code.
1.16.2.1	21-Jun-1999	thorpej	Sync w/ -current.
1.18.2.1	22-Jun-2000	minoura	Sync w/ netbsd-1-5-base.
1.21.2.11	11-Nov-2002	nathanw	Catch up to -current
1.21.2.10	18-Oct-2002	nathanw	Catch up to -current.
1.21.2.9	17-Sep-2002	nathanw	Catch up to -current.
1.21.2.8	12-Jul-2002	nathanw	No longer need to pull in lwp.h; proc.h pulls it in for us.
1.21.2.7	10-Jul-2002	nathanw	Whitespace.
1.21.2.6	24-Jun-2002	nathanw	Curproc->curlwp renaming. Change uses of "curproc->l_proc" back to "curproc", which is more like the original use. Bare uses of "curproc" are now "curlwp". "curproc" is now #defined in proc.h as ((curlwp) ? (curlwp)->l_proc) : NULL) so that it is always safe to reference curproc (dereferencing curproc is another story, but that's always been true).
1.21.2.5	01-Apr-2002	nathanw	Catch up to -current. (CVS: It's not just a program. It's an adventure!)
1.21.2.4	28-Mar-2002	ragge	curproc-> => curproc->l_proc->

1.24.4.2	13-Oct-2001	fvdl	Revert the t_dev -> t_devvp change in struct tty. The way that tty structs are currently used (especially by console ttys) aren't ready for it, and this will require quite a few changes.
1.24.4.1	10-Oct-2001	fvdl	Convert all remaining devices.
1.24.2.3	10-Oct-2002	jdolecek	sync kqueue with -current; this includes merge of gehenna-devsw branch, merge of i386 MP branch, and part of autoconf rototil work

1.34	26-Jun-2018	msaitoh	branches: 1.34.2; 1.34.10; Implement the BPF direction filter (BIOC[GS]DIRECTION). It provides backward compatibility with BIOC[GS]SEESENT ioctl. The userland interface is the same as FreeBSD. This change also fixes a bug that the direction is misunderstand on some environment by passing the direction to bpf_mtap*() instead of checking m->m_pkthdr.rcvif.
1.33	22-Jun-2018	msaitoh	It's not required to include net/bpfdesc.h. Remove it.
1.32	22-May-2017	ragge	branches: 1.32.2; 1.32.8; Update copyright notice for Ludd (remove clause 3 & 4).
1.31	15-Dec-2016	ozaki-r	Move bpf_mtap and if_ipackets++ on Rx of each driver to percpuq if_input The benefits of the change are: - We can reduce codes - We can provide the same behavior between drivers - Where/When if_ipackets is counted up - Note that some drivers still update packet statistics in their own way (periodical update) - Moved bpf_mtap run in softint - This makes it easy to MP-ify bpf Proposed on tech-kern and tech-net
1.30	09-Feb-2016	ozaki-r	branches: 1.30.2; Introduce softint-based if_input This change intends to run the whole network stack in softint context (or normal LWP), not hardware interrupt context. Note that the work is still incomplete by this change; to that end, we also have to softint-ify if_link_state_change (and bpf) which can still run in hardware interrupt. This change softint-ifies at ifp->if_input that is called from each device driver (and ieee80211_input) to ensure Layer 2 runs in softint (e.g., ether_input and bridge_input). To this end, we provide a framework (called percpuq) that utlizes softint(9) and percpu ifqueues. With this patch, rxintr of most drivers just queues received packets and schedules a softint, and the softint dequeues packets and does rest packet processing. To minimize changes to each driver, percpuq is allocated in struct ifnet for now and that is initialized by default (in if_attach). We probably have to move percpuq to softc of each driver, but it's future work. At this point, only wm(4) has percpuq in its softc as a reference implementation. Additional information including performance numbers can be found in the thread at tech-kern@ and tech-net@: http://mail-index.netbsd.org/tech-kern/2016/01/14/msg019997.html Acknowledgment: riastradh@ greatly helped this work. Thank you very much!
1.29	05-Apr-2010	joerg	branches: 1.29.18; 1.29.36; Push the bpf_ops usage back into bpf.h. Push the common ifp->if_bpf check into the inline functions as well the fourth argument for bpf_attach.
1.28	19-Jan-2010	pooka	branches: 1.28.2; 1.28.4; Redefine bpf linkage through an always present op vector, i.e. #if NBPFILTER is no longer required in the client. This change doesn't yet add support for loading bpf as a module, since drivers can register before bpf is attached. However, callers of bpf can now be modularized. Dynamically loadable bpf could probably be done fairly easily with coordination from the stub driver and the real driver by registering attachments in the stub before the real driver is loaded and doing a handoff. ... and I'm not going to ponder the depths of unload here. Tested with i386/MONOLITHIC, modified MONOLITHIC without bpf and rump.

Timing shows that it takes 4 times longer to map in the mbufs via the sgmap routines instead of just copying the data! This must be fixed sometine in the future. - A bunch of other minor fixes.

1.17	07-Nov-2008	dyoung	* Summary * When a link-layer address changes (e.g., ifconfig ex0 link 02:de:ad:be:ef:02 active), send a gratuitous ARP and/or a Neighbor Advertisement to update the network-/link-layer address bindings on our LAN peers. Refuse a change of ethernet address to the address 00:00:00:00:00:00 or to any multicast/broadcast address. (Thanks matt@.) Reorder ifnet ioctl operations so that driver ioctls may inherit the functions of their "class"---ether_ioctl(), fddi_ioctl(), et cetera---and the class ioctls may inherit from the generic ioctl, ifioctl_common(), but both driver- and class-ioctls may override the generic behavior. Make network drivers share more code. Distinguish a "factory" link-layer address from others for the purposes of both protecting that address from deletion and computing EUI64. Return consistent, appropriate error codes from network drivers. Improve readability. KNF. * Details * In if_attach(), always initialize the interface ioctl routine, ifnet->if_ioctl, if the driver has not already initialized it. Delete if_ioctl == NULL tests everywhere else, because it cannot happen. In the ioctl routines of network interfaces, inherit common ioctl behaviors by calling either ifioctl_common() or whichever ioctl routine is appropriate for the class of interface---e.g., ether_ioctl() for ethernets. Stop (ab)using SIOCSIFADDR and start to use SIOCINITIFADDR. In the user->kernel interface, SIOCSIFADDR's argument was an ifreq, but on the protocol->ifnet interface, SIOCSIFADDR's argument was an ifaddr. That was confusing, and it would work against me as I make it possible for a network interface to overload most ioctls. On the protocol->ifnet interface, replace SIOCSIFADDR with SIOCINITIFADDR. In ifioctl(), return EPERM if userland tries to invoke SIOCINITIFADDR. In ifioctl(), give the interface the first shot at handling most interface ioctls, and give the protocol the second shot, instead of the other way around. Finally, let compatibility code (COMPAT_OSOCK) take a shot. Pull device initialization out of switch statements under SIOCINITIFADDR. For example, pull ..._init() out of any switch statement that looks like this: switch (...->sa_family) { case ...: ..._init(); ... break; ... default: ..._init(); ... break; } Rewrite many if-else clauses that handle all permutations of IFF_UP and IFF_RUNNING to use a switch statement, switch (x & (IFF_UP\|IFF_RUNNING)) { case 0: ... break; case IFF_RUNNING: ... break; case IFF_UP: ... break; case IFF_UP\|IFF_RUNNING: ... break; } unifdef lots of code containing #ifdef FreeBSD, #ifdef NetBSD, and #ifdef SIOCSIFMTU, especially in fwip(4) and in ndis(4). In ipw(4), remove an if_set_sadl() call that is out of place. In nfe(4), reuse the jumbo MTU logic in ether_ioctl(). Let ethernets register a callback for setting h/w state such as promiscuous mode and the multicast filter in accord with a change in the if_flags: ether_set_ifflags_cb() registers a callback that returns ENETRESET if the caller should reset the ethernet by calling if_init(), 0 on success, != 0 on failure. Pull common code from ex(4), gem(4), nfe(4), sip(4), tlp(4), vge(4) into ether_ioctl(), and register if_flags callbacks for those drivers. Return ENOTTY instead of EINVAL for inappropriate ioctls. In zyd(4), use ENXIO instead of ENOTTY to indicate that the device is not any longer attached. Add to if_set_sadl() a boolean 'factory' argument that indicates whether a link-layer address was assigned by the factory or some other source. In a comment, recommend using the factory address for generating an EUI64, and update in6_get_hw_ifid() to prefer a factory address to any other link-layer address. Add a routing message, RTM_LLINFO_UPD, that tells protocols to update the binding of network-layer addresses to link-layer addresses. Implement this message in IPv4 and IPv6 by sending a gratuitous ARP or a neighbor advertisement, respectively. Generate RTM_LLINFO_UPD messages on a change of an interface's link-layer address. In ether_ioctl(), do not let SIOCALIFADDR set a link-layer address that is broadcast/multicast or equal to 00:00:00:00:00:00. Make ether_ioctl() call ifioctl_common() to handle ioctls that it does not understand. In gif(4), initialize if_softc and use it, instead of assuming that the gif_softc and ifp overlap. Let ifioctl_common() handle SIOCGIFADDR. Sprinkle rtcache_invariants(), which checks on DIAGNOSTIC kernels that certain invariants on a struct route are satisfied. In agr(4), rewrite agr_ioctl_filter() to be a bit more explicit about the ioctls that we do not allow on an agr(4) member interface. bzero -> memset. Delete unnecessary casts to void . Use sockaddr_in_init() and sockaddr_in6_init(). Compare pointers with NULL instead of "testing truth". Replace some instances of (type )0 with NULL. Change some K&R prototypes to ANSI C, and join lines.

Note that the work is still incomplete by this change; to that end, we also have to softint-ify if_link_state_change (and bpf) which can still run in hardware interrupt. This change softint-ifies at ifp->if_input that is called from each device driver (and ieee80211_input) to ensure Layer 2 runs in softint (e.g., ether_input and bridge_input). To this end, we provide a framework (called percpuq) that utlizes softint(9) and percpu ifqueues. With this patch, rxintr of most drivers just queues received packets and schedules a softint, and the softint dequeues packets and does rest packet processing. To minimize changes to each driver, percpuq is allocated in struct ifnet for now and that is initialized by default (in if_attach). We probably have to move percpuq to softc of each driver, but it's future work. At this point, only wm(4) has percpuq in its softc as a reference implementation. Additional information including performance numbers can be found in the thread at tech-kern@ and tech-net@: http://mail-index.netbsd.org/tech-kern/2016/01/14/msg019997.html Acknowledgment: riastradh@ greatly helped this work.

They are counterpart of m_get_rcvif, which will come in another commit, hide internal of rcvif operation, and reduce the diff of the upcoming change. No functional change.
1.74	09-Feb-2016	ozaki-r	Introduce softint-based if_input This change intends to run the whole network stack in softint context (or normal LWP), not hardware interrupt context. Note that the work is still incomplete by this change; to that end, we also have to softint-ify if_link_state_change (and bpf) which can still run in hardware interrupt. This change softint-ifies at ifp->if_input that is called from each device driver (and ieee80211_input) to ensure Layer 2 runs in softint (e.g., ether_input and bridge_input). To this end, we provide a framework (called percpuq) that utlizes softint(9) and percpu ifqueues. With this patch, rxintr of most drivers just queues received packets and schedules a softint, and the softint dequeues packets and does rest packet processing. To minimize changes to each driver, percpuq is allocated in struct ifnet for now and that is initialized by default (in if_attach). We probably have to move percpuq to softc of each driver, but it's future work. At this point, only wm(4) has percpuq in its softc as a reference implementation. Additional information including performance numbers can be found in the thread at tech-kern@ and tech-net@: http://mail-index.netbsd.org/tech-kern/2016/01/14/msg019997.html Acknowledgment: riastradh@ greatly helped this work.

This change doesn't yet add support for loading bpf as a module, since drivers can register before bpf is attached. However, callers of bpf can now be modularized. Dynamically loadable bpf could probably be done fairly easily with coordination from the stub driver and the real driver by registering attachments in the stub before the real driver is loaded and doing a handoff. ... and I'm not going to ponder the depths of unload here. Tested with i386/MONOLITHIC, modified MONOLITHIC without bpf and rump.
1.69	18-Mar-2009	cegger	bzero -> memset
1.68	07-Nov-2008	dyoung	branches: 1.68.4; * Summary * When a link-layer address changes (e.g., ifconfig ex0 link 02:de:ad:be:ef:02 active), send a gratuitous ARP and/or a Neighbor Advertisement to update the network-/link-layer address bindings on our LAN peers. Refuse a change of ethernet address to the address 00:00:00:00:00:00 or to any multicast/broadcast address. (Thanks matt@.) Reorder ifnet ioctl operations so that driver ioctls may inherit the functions of their "class"---ether_ioctl(), fddi_ioctl(), et cetera---and the class ioctls may inherit from the generic ioctl, ifioctl_common(), but both driver- and class-ioctls may override the generic behavior. Make network drivers share more code. Distinguish a "factory" link-layer address from others for the purposes of both protecting that address from deletion and computing EUI64. Return consistent, appropriate error codes from network drivers. Improve readability. KNF. * Details * In if_attach(), always initialize the interface ioctl routine, ifnet->if_ioctl, if the driver has not already initialized it. Delete if_ioctl == NULL tests everywhere else, because it cannot happen. In the ioctl routines of network interfaces, inherit common ioctl behaviors by calling either ifioctl_common() or whichever ioctl routine is appropriate for the class of interface---e.g., ether_ioctl() for ethernets. Stop (ab)using SIOCSIFADDR and start to use SIOCINITIFADDR. In the user->kernel interface, SIOCSIFADDR's argument was an ifreq, but on the protocol->ifnet interface, SIOCSIFADDR's argument was an ifaddr. That was confusing, and it would work against me as I make it possible for a network interface to overload most ioctls. On the protocol->ifnet interface, replace SIOCSIFADDR with SIOCINITIFADDR. In ifioctl(), return EPERM if userland tries to invoke SIOCINITIFADDR. In ifioctl(), give the interface the first shot at handling most interface ioctls, and give the protocol the second shot, instead of the other way around. Finally, let compatibility code (COMPAT_OSOCK) take a shot. Pull device initialization out of switch statements under SIOCINITIFADDR. For example, pull ..._init() out of any switch statement that looks like this: switch (...->sa_family) { case ...: ..._init(); ... break; ... default: ..._init(); ... break; } Rewrite many if-else clauses that handle all permutations of IFF_UP and IFF_RUNNING to use a switch statement, switch (x & (IFF_UP\|IFF_RUNNING)) { case 0: ... break; case IFF_RUNNING: ... break; case IFF_UP: ... break; case IFF_UP\|IFF_RUNNING: ... break; } unifdef lots of code containing #ifdef FreeBSD, #ifdef NetBSD, and #ifdef SIOCSIFMTU, especially in fwip(4) and in ndis(4). In ipw(4), remove an if_set_sadl() call that is out of place. In nfe(4), reuse the jumbo MTU logic in ether_ioctl(). Let ethernets register a callback for setting h/w state such as promiscuous mode and the multicast filter in accord with a change in the if_flags: ether_set_ifflags_cb() registers a callback that returns ENETRESET if the caller should reset the ethernet by calling if_init(), 0 on success, != 0 on failure. Pull common code from ex(4), gem(4), nfe(4), sip(4), tlp(4), vge(4) into ether_ioctl(), and register if_flags callbacks for those drivers. Return ENOTTY instead of EINVAL for inappropriate ioctls. In zyd(4), use ENXIO instead of ENOTTY to indicate that the device is not any longer attached. Add to if_set_sadl() a boolean 'factory' argument that indicates whether a link-layer address was assigned by the factory or some other source. In a comment, recommend using the factory address for generating an EUI64, and update in6_get_hw_ifid() to prefer a factory address to any other link-layer address. Add a routing message, RTM_LLINFO_UPD, that tells protocols to update the binding of network-layer addresses to link-layer addresses. Implement this message in IPv4 and IPv6 by sending a gratuitous ARP or a neighbor advertisement, respectively. Generate RTM_LLINFO_UPD messages on a change of an interface's link-layer address. In ether_ioctl(), do not let SIOCALIFADDR set a link-layer address that is broadcast/multicast or equal to 00:00:00:00:00:00. Make ether_ioctl() call ifioctl_common() to handle ioctls that it does not understand. In gif(4), initialize if_softc and use it, instead of assuming that the gif_softc and ifp overlap. Let ifioctl_common() handle SIOCGIFADDR. Sprinkle rtcache_invariants(), which checks on DIAGNOSTIC kernels that certain invariants on a struct route are satisfied. In agr(4), rewrite agr_ioctl_filter() to be a bit more explicit about the ioctls that we do not allow on an agr(4) member interface. bzero -> memset. Delete unnecessary casts to void . Use sockaddr_in_init() and sockaddr_in6_init(). Compare pointers with NULL instead of "testing truth". Replace some instances of (type )0 with NULL. Change some K&R prototypes to ANSI C, and join lines.

1.56	15-Jan-2003	bouyer	Zero out the extra space stolen from mbuf to pad packet to ETHER_MIN_LEN XXX should it be ETHER_MIN_LEN - ETHER_CRC_LEN ? XXX2 we assume there are enouth space in the mbuf for the padding bytes. But other places in the code assumes this already.
1.55	02-Oct-2002	thorpej	Add trailing ; to CFATTACH_DECL.
1.54	30-Sep-2002	thorpej	Use CFATTACH_DECL().
1.53	27-Sep-2002	thorpej	Declare all cfattach structures const.
1.52	27-Sep-2002	provos	remove trailing \n in panic(). approved perry.
1.51	08-Jun-2002	ragge	Detection bug: If a packet is received while in the match() routine the stack would be overwritten, so allocate memory for a full packet via malloc() instead. Use correct buffer maxlen (must be 2 complemet). Bug reported and helped to find by Roar Thron�s.
1.50	22-May-2002	wiz	bcmp -> memcmp.
1.49	13-Nov-2001	lukem	branches: 1.49.8; 1.49.10; add RCSIDs
1.48	26-Apr-2001	ragge	branches: 1.48.2; Use uballoc()/ubmemalloc() for data structure allocation.
1.47	12-Apr-2001	thorpej	splimp -> splnet
1.46	25-Feb-2001	ragge	branches: 1.46.2; Do not send looped-back setup packets into the IP stack. Handle xmit interrupts due to invalid transmit list (``cannot happen'') Shoot the one that wrote the software for those cards.
1.45	14-Dec-2000	thorpej	ALTQ'ify.
1.44	15-Nov-2000	thorpej	Move bpfattach()/bpfdetach() calls into ether_ifattach()/ether_ifdetach().
1.43	01-Oct-2000	thorpej	Move the check for "promisc + unicast + not for us" into ether_input(), and change Ethernet drivers to always pass all received frames to ether_input() (with a few exceptions, which are documented in the code).
1.42	05-Jun-2000	matt	Adjust to new evcnt stuff.
1.41	04-Jun-2000	matt	More event counter stuff. Plus a little cruft cleanup while doing it.
1.40	30-Mar-2000	augustss	branches: 1.40.2; Remove register declarations.
1.39	24-Jan-2000	matt	Revamp the VAX interrupt handling code. Make it compatible with all the other ports. Clean up some things.
1.38	01-Aug-1999	ragge	branches: 1.38.2; Add a timeout-routine that checks if transmit logic dies, and reset it in that case. This is not uncommon when the interface is heavy loaded.
1.37	20-Jun-1999	ragge	branches: 1.37.2; Totally rewritten DEQNA device driver, that uses the bus.h interface instead. This almost doubled the receive speed of the interface :-)
1.36	06-Jun-1999	ragge	Copied from ../../arch/vax/if/if_qe.c,v
1.35	23-May-1999	ragge	Make this file compile again.
1.34	18-May-1999	thorpej	Rework layer 2 protocol input routines. Instead of calling e.g. ether_input() directly, call the function pointer (if_input)(ifp, m). The input routine expects the packet header to be at the head of the packet, and will adjust as necessary. Privatize the layer 2 input and output routines, allowing _ifattach() to set them up as appropriate.
1.33	29-Nov-1998	ragge	branches: 1.33.2; the btoc/ctob/btop macros must use CLBYTES, not NBPG. How this should work in the long run is an open issue; some parts must be reworked in a MI way.
1.32	05-Nov-1998	ragge	EGCS fixes.
1.31	05-Jul-1998	jonathan	defopt NS, NSIP.

1.26	20-Jun-1998	ragge	Fix some compile-time warnings. Pointed out by David Brownlee.
1.25	13-Mar-1998	ragge	Add support for "root on qe".
1.24	24-Jan-1998	ragge	Remove __BROKEN_INDIRECT_CONFIG and change all drivers to use config_search instead.
1.23	12-Jan-1998	thorpej	Update for changes to config.
1.22	02-May-1997	ragge	BPF and multicast support added, patches provided by Jonathan Stone and Ken Wellsch. Fixes PR#2796.
1.21	19-Apr-1997	ragge	Fix so that these files compile again after recent ARP changes.
1.20	15-Mar-1997	is	New ARP system, supports IPv4 over any hardware link. Some of the stuff (e.g., rarpd, bootpd, dhcpd etc., libsa) still will only support Ethernet. Tcpdump itself should be ok, but libpcap needs lot of work. For the detailed change history, look at the commit log entries for the is-newarp branch.
1.19	12-Feb-1997	ragge	Fix so it works with root over NFS.
1.18	13-Oct-1996	christos	branches: 1.18.6; backout previous kprintf change
1.17	11-Oct-1996	christos	printf -> kprintf, sprintf -> ksprintf
1.16	20-Aug-1996	ragge	Change uba* functions to take pointers, rather than uba unit numbers.
1.15	19-May-1996	ragge	Fixed all (proto)type errors. Fixes PR 2377.
1.14	07-May-1996	thorpej	Changed struct ifnet to have a pointer to the softc of the underlying device and a printable "external name" (name + unit number), thus eliminating if_name and if_unit. Updated interface to (if_watchdog)() and (if_start)() to take a struct ifnet *, rather than a unit number.
1.13	18-Mar-1996	ragge	Ubareset are now possible, devices that wants it now set it up during autoconfig. ifubareset (if_reset) no longer used, actually it's just a normal ubareset and is now handled like that.
1.12	17-Mar-1996	ragge	Convert all devices according to the changes to config.
1.11	11-Feb-1996	ragge	Add prototypes.
1.10	02-Feb-1996	mycroft	Fix #includes.
1.9	02-Feb-1996	mycroft	Fix #includes.
1.8	24-Dec-1995	mycroft	The IST_* and IPL_* constants are not bus-specific; don't treat them as such. Change splimp -> splnet in Ethernet, ARCnet, and FDDI drivers.
1.7	01-Dec-1995	ragge	DELUA/DENUA & DELQA/DEQNA Ethernet adapters converted to new config.
1.6	30-Nov-1995	jtc	merge in changes from 1.1 release branch
1.5	10-Nov-1995	ragge	Dynamic allocate uba_softc and interrupt vectors. Allow for more that one uba.

1.4.2.1	15-Oct-1995	ragge	Type changing to be able to compile with -Werror.
1.18.6.3	10-Mar-1997	is	netinet/if_ether.h => netinet/if_inarp.h
1.18.6.2	06-Mar-1997	is	Merge in fix from the Trunk.
1.18.6.1	06-Mar-1997	is	Convert to new ARP code.
1.33.2.1	11-Dec-1998	kenh	The beginnings of interface detach support. Still some bugs, but mostly works for me. This work was originally by Bill Studenmund, and cleaned up by me.

1.23	26-Jun-2018	msaitoh	branches: 1.23.2; 1.23.8; Implement the BPF direction filter (BIOC[GS]DIRECTION). It provides backward compatibility with BIOC[GS]SEESENT ioctl. The userland interface is the same as FreeBSD. This change also fixes a bug that the direction is misunderstand on some environment by passing the direction to bpf_mtap*() instead of checking m->m_pkthdr.rcvif.

1.20	12-Dec-2016	maya	acknowleg -> acknowledg, proceedure -> procedure. only comments were changed. from miod
1.19	09-Feb-2016	ozaki-r	branches: 1.19.2; Introduce softint-based if_input This change intends to run the whole network stack in softint context (or normal LWP), not hardware interrupt context. Note that the work is still incomplete by this change; to that end, we also have to softint-ify if_link_state_change (and bpf) which can still run in hardware interrupt. This change softint-ifies at ifp->if_input that is called from each device driver (and ieee80211_input) to ensure Layer 2 runs in softint (e.g., ether_input and bridge_input). To this end, we provide a framework (called percpuq) that utlizes softint(9) and percpu ifqueues. With this patch, rxintr of most drivers just queues received packets and schedules a softint, and the softint dequeues packets and does rest packet processing. To minimize changes to each driver, percpuq is allocated in struct ifnet for now and that is initialized by default (in if_attach). We probably have to move percpuq to softc of each driver, but it's future work. At this point, only wm(4) has percpuq in its softc as a reference implementation. Additional information including performance numbers can be found in the thread at tech-kern@ and tech-net@: http://mail-index.netbsd.org/tech-kern/2016/01/14/msg019997.html Acknowledgment: riastradh@ greatly helped this work. Thank you very much!
1.18	05-Apr-2010	joerg	branches: 1.18.18; 1.18.36; Push the bpf_ops usage back into bpf.h. Push the common ifp->if_bpf check into the inline functions as well the fourth argument for bpf_attach.
1.17	19-Jan-2010	pooka	branches: 1.17.2; 1.17.4; Redefine bpf linkage through an always present op vector, i.e. #if NBPFILTER is no longer required in the client. This change doesn't yet add support for loading bpf as a module, since drivers can register before bpf is attached. However, callers of bpf can now be modularized. Dynamically loadable bpf could probably be done fairly easily with coordination from the stub driver and the real driver by registering attachments in the stub before the real driver is loaded and doing a handoff. ... and I'm not going to ponder the depths of unload here. Tested with i386/MONOLITHIC, modified MONOLITHIC without bpf and rump.

1.32	10-Jun-2016	ozaki-r	Introduce m_set_rcvif and m_reset_rcvif The API is used to set (or reset) a received interface of a mbuf. They are counterpart of m_get_rcvif, which will come in another commit, hide internal of rcvif operation, and reduce the diff of the upcoming change. No functional change.
1.31	13-Nov-2010	uebayasi	branches: 1.31.18; 1.31.36; Don't pull in the whole uvm(9) API to access only PAGE_SIZE and some other constants. These are provided by sys/param.h now.

1.15	01-Jan-1999	ragge	Giant change: NBPG now set to 4k and CLSIZE == 1 for vax. This change made a whole bunch of annoying bugs disappear; mostly depending on bad use of NBPG in non-MD code. The VAX port was the only port that used this historical "feature". The CL* macros should probably go away totally, there is no reason at all to keep them.
1.14	29-Nov-1998	ragge	branches: 1.14.2; the btoc/ctob/btop macros must use CLBYTES, not NBPG. How this should work in the long run is an open issue; some parts must be reworked in a MI way.

1.16.4.1	20-Nov-2000	bouyer	Remove files that are no longer on the trunck, and commit Makefile which I forgot in the batch of commits.

1.59	26-Sep-2021	thorpej	Change the kqueue filterops::f_isfd field to filterops::f_flags, and define a flag FILTEROP_ISFD that has the meaning of the prior f_isfd. Field and flag name aligned with OpenBSD. This does not constitute a functional or ABI change, as the field location and size, and the value placed in that field, are the same as the previous code, but we're bumping __NetBSD_Version__ so 3rd-party module source code can adapt, as needed. NetBSD 9.99.89
1.58	18-Dec-2020	thorpej	Use sel{record,remove}_knote().
1.57	25-Oct-2017	maya	branches: 1.57.18; Use C99 initializer for filterops Mostly done with spatch with touchups for indentation @@ expression a; identifier b,c,d; identifier p; @@ const struct filterops p = - { a, b, c, d + { + .f_isfd = a, + .f_attach = b, + .f_detach = c, + .f_event = d, };
1.56	18-Oct-2014	snj	src is too big these days to tolerate superfluous apostrophes. It's "its", people!
1.55	25-Jul-2014	dholland	Add d_discard to all struct cdevsw instances I could find. All have been set to "nodiscard"; some should get a real implementation.
1.54	16-Mar-2014	dholland	branches: 1.54.2; Change (mostly mechanically) every cdevsw/bdevsw I can find to use designated initializers. I have not built every extant kernel so I have probably broken at least one build; however I've also found and fixed some wrong cdevsw/bdevsw entries so even if so I think we come out ahead.
1.53	27-Oct-2012	chs	branches: 1.53.2; split device_t/softc for all remaining drivers. replace "struct device *" with "device_t". use device_xname(), device_unit(), etc.

1.46	14-Mar-2009	dsl	ANSIfy another 1261 function definitions. The only ones left in sys are beyond by sed script! (or in sys/dist or sys/external) Mostly they have function pointer parameters.
1.45	14-Mar-2009	dsl	Change about 4500 of the K&R function definitions to ANSI ones. There are still about 1600 left, but they have ',' or /* ... */ in the actual variable definitions - which my awk script doesn't handle. There are also many that need () -> (void). (The script does handle misordered arguments.)

1.42	01-Mar-2008	rmind	Welcome to 4.99.55: - Add a lot of missing selinit() and seldestroy() calls. - Merge selwakeup() and selnotify() calls into a single selnotify(). - Add an additional 'events' argument to selnotify() call. It will indicate which event (POLL_IN, POLL_OUT, etc) happen. If unknown, zero may be used. Note: please pass appropriate value of 'events' where possible. Proposed on: <tech-kern>

1.30	26-Nov-2002	christos	branches: 1.30.6; si_ -> sel_
1.29	23-Oct-2002	jdolecek	merge kqueue branch into -current kqueue provides a stateful and efficient event notification framework currently supported events include socket, file, directory, fifo, pipe, tty and device changes, and monitoring of processes and signals kqueue is supported by all writable filesystems in NetBSD tree (with exception of Coda) and all device drivers supporting poll(2) based on work done by Jonathan Lemon for FreeBSD initial NetBSD port done by Luke Mewburn and Jason Thorpe
1.28	02-Oct-2002	thorpej	Add trailing ; to CFATTACH_DECL.
1.27	30-Sep-2002	thorpej	Use CFATTACH_DECL().
1.26	27-Sep-2002	thorpej	Declare all cfattach structures const.
1.25	06-Sep-2002	gehenna	Merge the gehenna-devsw branch into the trunk. This merge changes the device switch tables from static array to dynamically generated by config(8). - All device switches is defined as a constant structure in device drivers. - The new grammer ``device-major'' is introduced to ``files''. device-major <prefix> char <num> [block <num>] [<rules>] - All device major numbers must be listed up in port dependent majors.<arch> by using this grammer. - Added the new naming convention. The name of the device switch must be <prefix>_[bc]devsw for auto-generation of device switch tables. - The backward compatibility of loading block/character device switch by LKM framework is broken. This is necessary to convert from block/character device major to device name in runtime and vice versa. - The restriction to assign device major by LKM is completely removed. We don't need to reserve LKM entries for dynamic loading of device switch. - In compile time, device major numbers list is packed into the kernel and the LKM framework will refer it to assign device major number dynamically.
1.24	17-Mar-2002	atatat	branches: 1.24.4; Convert ioctl code to use EPASSTHROUGH instead of -1 or ENOTTY for indicating an unhandled "command". ERESTART is -1, which can lead to confusion. ERESTART has been moved to -3 and EPASSTHROUGH has been placed at -4. No ioctl code should now return -1 anywhere. The ioctl() system call is now properly restartable.
1.23	13-Nov-2001	lukem	add RCSIDs
1.22	02-May-2001	scw	branches: 1.22.2; 1.22.4; Add `l_poll' to `struct linesw' and provide an xxxpoll() entry point in each tty driver to indirect through it. This allows tty line-disciplines to handle poll(2) system calls.

1.13	17-Apr-1999	ragge	Only allocate QDSS memory if there is a QDSS as console. QDSS should also work on KA650 now. (untested)
1.12	19-Jan-1999	ragge	Allocate (almost) all interrupt vectors dynamically. Simplifies much work when adding support for new machines and devices.
1.11	01-Jan-1999	ragge	Giant change: NBPG now set to 4k and CLSIZE == 1 for vax. This change made a whole bunch of annoying bugs disappear; mostly depending on bad use of NBPG in non-MD code. The VAX port was the only port that used this historical "feature". The CL* macros should probably go away totally, there is no reason at all to keep them.
1.10	29-Nov-1998	ragge	the btoc/ctob/btop macros must use CLBYTES, not NBPG. How this should work in the long run is an open issue; some parts must be reworked in a MI way.
1.9	05-Nov-1998	ragge	EGCS fixes.
1.8	04-Jul-1998	jonathan	defopt DDB.

1.2	02-Sep-1996	mycroft	tty stop functions really should return void, not int, and certainly not both.
1.1	18-Aug-1996	jonathan	Import framebuffer drivers from 4.4-Lite2 as the root for NetBSD drivers. Only change from Lite (or lite2, qv.c and qd.c do not change) is adding NetBSD RCS ids.

Adjust all call sites: - Simplify wherever possible; don't pass along arguments that aren't actually needed. - Don't be explicit about what interface attribute is attaching if the device only has one. (More simplification.) - Add a config_probe() function to be used in indirect configuiration situations, making is visibly easier to see when indirect config is in play, and allowing for future change in semantics. (As of now, this is just a wrapper around config_match(), but that is an implementation detail.) Remove unnecessary or redundant interface attributes where they're not needed. There are currently 5 "cfargs" defined: - CFARG_SUBMATCH (submatch function for direct config) - CFARG_SEARCH (search function for indirect config) - CFARG_IATTR (interface attribte) - CFARG_LOCATORS (locators array) - CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles) ...and a sentinel value CFARG_EOL. Add some extra sanity checking to ensure that interface attributes aren't ambiguous. Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark ports to associate those device handles with device_t instance. This will trickle trough to more places over time (need back-end for pre-OFW Sun OBP; any others?).
1.34	29-Oct-2019	christos	branches: 1.34.10; Implement what the documentation in rfreg.h states, and do not apply the wrong mask to the command register (which kind of works, but really?!?!) Found by gcc -Wtautological-compare
1.33	08-Dec-2015	christos	branches: 1.33.18; Replace DIOCGPART -> DIOCGPARTINFO which returns the data needed instead of pointers.
1.32	26-Apr-2015	mlelstv	Use C99-style initializers for struct dkdriver.
1.31	02-Jan-2015	christos	We have three sets of DTYPE_ constants in the kernel: altq Drop Type disklabel Disk Type file Descriptor Type (not to mention constants that contain the string DTYPE). Let's make them two, by changing the disklabel one to be DisK TYPE since the other disklabel constants seem to do that. Not many userland programs use these constants (and the ones that they do are mostly in ifdefs). They will be fixed shortly.
1.30	31-Dec-2014	christos	make more drivers use disk_ioctl, and add a dev parameter to it so that we can merge the "easy" disklabel ioctls to it. Ultimately all this will go do dk_ioctl once all the drivers have been converted.

This merge changes the device switch tables from static array to dynamically generated by config(8). - All device switches is defined as a constant structure in device drivers. - The new grammer ``device-major'' is introduced to ``files''. device-major <prefix> char <num> [block <num>] [<rules>] - All device major numbers must be listed up in port dependent majors.<arch> by using this grammer. - Added the new naming convention. The name of the device switch must be <prefix>_[bc]devsw for auto-generation of device switch tables. - The backward compatibility of loading block/character device switch by LKM framework is broken. This is necessary to convert from block/character device major to device name in runtime and vice versa. - The restriction to assign device major by LKM is completely removed. We don't need to reserve LKM entries for dynamic loading of device switch. - In compile time, device major numbers list is packed into the kernel and the LKM framework will refer it to assign device major number dynamically.

1.3	19-May-2000	thorpej	branches: 1.3.2; A foolish consistency; most parts of the kernel use bp->b_data, so change these from bp->b_un.b_addr to bp->b_data, as well. This also allows us more flexibility to experiment with other data buffer types hung off of struct buf.

1.11	16-Apr-2020	rin	Revert previous for now: http://mail-index.netbsd.org/source-changes/2020/04/16/msg116278.html The reasoning turned out to be wrong; __KERNEL_RCSID() in header files does not overwrite RCSID in main source files. The real problem is that it inserts its RCSID into every object files. However, it can be still useful even if heavily duplicated.
1.10	16-Apr-2020	rin	Stop using __KERNEL_RCSID() in header files; it confuses ident(1) by overwriting RCSID in main source files. XXX The first argument of __KERNEL_RCSID() is neglected for ELF. If we wish to have RCSID of header files in kernel binary, we need something like __FBSDID() macro in FreeBSD.

This merge changes the device switch tables from static array to dynamically generated by config(8). - All device switches is defined as a constant structure in device drivers. - The new grammer ``device-major'' is introduced to ``files''. device-major <prefix> char <num> [block <num>] [<rules>] - All device major numbers must be listed up in port dependent majors.<arch> by using this grammer. - Added the new naming convention. The name of the device switch must be <prefix>_[bc]devsw for auto-generation of device switch tables. - The backward compatibility of loading block/character device switch by LKM framework is broken. This is necessary to convert from block/character device major to device name in runtime and vice versa. - The restriction to assign device major by LKM is completely removed. We don't need to reserve LKM entries for dynamic loading of device switch. - In compile time, device major numbers list is packed into the kernel and the LKM framework will refer it to assign device major number dynamically.

1.83	07-Aug-2021	thorpej	Merge thorpej-cfargs2.
1.82	24-Apr-2021	thorpej	branches: 1.82.8; Merge thorpej-cfargs branch: Simplify and make extensible the config_search() / config_found() / config_attach() interfaces: rather than having different variants for which arguments you want pass along, just have a single call that takes a variadic list of tag-value arguments. Adjust all call sites: - Simplify wherever possible; don't pass along arguments that aren't actually needed. - Don't be explicit about what interface attribute is attaching if the device only has one. (More simplification.) - Add a config_probe() function to be used in indirect configuiration situations, making is visibly easier to see when indirect config is in play, and allowing for future change in semantics. (As of now, this is just a wrapper around config_match(), but that is an implementation detail.) Remove unnecessary or redundant interface attributes where they're not needed. There are currently 5 "cfargs" defined: - CFARG_SUBMATCH (submatch function for direct config) - CFARG_SEARCH (search function for indirect config) - CFARG_IATTR (interface attribte) - CFARG_LOCATORS (locators array) - CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles) ...and a sentinel value CFARG_EOL. Add some extra sanity checking to ensure that interface attributes aren't ambiguous. Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark ports to associate those device handles with device_t instance. This will trickle trough to more places over time (need back-end for pre-OFW Sun OBP; any others?).

1.49	24-Jan-2000	matt	Revamp the VAX interrupt handling code. Make it compatible with all the other ports. Clean up some things.

1.47	06-Jun-1999	ragge	Fix map register/DMA wait queues. Still to do: BDP handling. Currently missing. Ubareset's won't work at all.
1.46	27-May-1999	ragge	Moved from ../dec/qbus/uba.c,v
1.45	27-May-1999	ragge	Directory called qbus instead of uba, per request from Matt/Jason/... (More describing name actually)
1.44	26-May-1999	ragge	DZ-11 routines bus'ified. Small fixes to uba routines.
1.43	24-May-1999	ragge	First step towards MI Unibus/Q22 bus code.
1.42	02-Feb-1999	ragge	Another giant change: Allocate register space dynamic instead of compiled-in. This is done on a physical page size basis, instead of virtual (as the (on vax yet non-existing) bus_* routines does). This is similar to the way uba allocation is done.
1.41	19-Jan-1999	ragge	Fix some void pointers.
1.40	19-Jan-1999	ragge	Allocate (almost) all interrupt vectors dynamically. Simplifies much work when adding support for new machines and devices.
1.39	01-Jan-1999	ragge	Giant change: NBPG now set to 4k and CLSIZE == 1 for vax. This change made a whole bunch of annoying bugs disappear; mostly depending on bad use of NBPG in non-MD code. The VAX port was the only port that used this historical "feature". The CL* macros should probably go away totally, there is no reason at all to keep them.
1.38	29-Nov-1998	ragge	the btoc/ctob/btop macros must use CLBYTES, not NBPG. How this should work in the long run is an open issue; some parts must be reworked in a MI way.
1.37	05-Nov-1998	ragge	EGCS fixes.
1.36	18-Oct-1998	ragge	Support for DWBUA (BI to Unibus adapter) and KLESI-B (TMSCP tape ctlr) added.
1.35	06-Oct-1998	matt	Change backplace0 to mainbus0 (for consistency with other ports). Remove unused function protocols from ka410.h and ka43.h Fix some ka46 missing references
1.34	21-Mar-1998	ragge	ubasetup() must be non-static. (used by QDSS)
1.33	02-Mar-1998	ragge	Support for UVM on VAXen.

1.30	12-Jan-1998	thorpej	Update for changes to config.
1.29	13-Oct-1996	christos	backout previous kprintf change
1.28	11-Oct-1996	christos	printf -> kprintf, sprintf -> ksprintf
1.27	27-Aug-1996	cgd	change cfprint_t type definition to take a const char , rather than a char , because that's what was really intended, and because if the print function modifies the string, various things could become unhappy (so the string should _not_ be modified).
1.26	20-Aug-1996	ragge	Modified to get cleaner match/attach code for different parent buses. Fix so that resource wait queueing works. Changed all functions to take a pointer to uba_softc instead of unit number, except for ubareset(). This must be done later.
1.25	20-Jul-1996	ragge	CPU determine code. ts driver converted to new config. May work, untested.
1.24	11-Jul-1996	ragge	Automatic changing of root device after boot now works.
1.23	01-Jul-1996	ragge	Remove code that took care of old config devices. Don't support old config anymore, all devices should use new config by now. Add structures to handle DMA devices using new config. Fixed bug that caused unwanted ubareset's on 11/780.
1.22	08-Apr-1996	ragge	Added prototypes to everything. Made all files compile with -Wall.
1.21	18-Mar-1996	ragge	Ubareset are now possible, devices that wants it now set it up during autoconfig. ifubareset (if_reset) no longer used, actually it's just a normal ubareset and is now handled like that.
1.20	17-Mar-1996	ragge	Convert all devices according to the changes to config.
1.19	09-Mar-1996	ragge	Check on which SBI we are frobbing, not always 0.
1.18	07-Mar-1996	ragge	Support for VAX 8600/8650 added. Works with lots of Unibus adapters, and will probably work with Massbus adapters as well. (Not tested, but it's the same code as for 11/780). Ubareset's may cause crashes on 8600 also like 11/780, but they are more uncommon. No support for console RL02 yet, but it's likely to come.
1.17	02-Mar-1996	ragge	Add support for DW780. Note that ubareset's don't work properly. This is not a problem on other Unibus adapters, but DW780's do ubareset's more often. This needs to be fixed by someone someday.
1.16	11-Feb-1996	ragge	Remove csralloc(), not usable anymore. Add ubasetvec() to steal interrupt vectors for device drivers that need more than one vector. Add prototype for it.
1.15	02-Feb-1996	mycroft	Fix type errors.
1.14	02-Feb-1996	mycroft	Fix #includes.
1.13	02-Feb-1996	mycroft	Fix #includes.
1.12	28-Dec-1995	thorpej	Move the old-style disk instrumentation "structures" to a central location (sys/kern/subr_disk.c) and note that they should/will be deperecated.
1.11	13-Dec-1995	ragge	MicroVAX III support added. Dummy match/attach routines for tmscp. Conversion of uda.c towards new config.
1.10	01-Dec-1995	ragge	UBA converted to new config. (uba's now can be *'ed). Bug causing DMA writes to nonexistent memory pages fixed. Code for old config of non-mass-storage devices removed. (they now must use new config).
1.9	10-Nov-1995	ragge	Dynamic allocate uba_softc and interrupt vectors. Allow for more that one uba.
1.8	16-Jun-1995	ragge	d_reset reference removed. Calling of ubareset must be solved.
1.7	30-Mar-1995	ragge	Bug fixes of interrupt handlers.
1.6	23-Feb-1995	ragge	Support for uVAXII, new tmscp driver added.

1.81.10.2	21-Mar-2021	thorpej	CFARG_IATTR usage audit: If a device carries only one interface attribute, there is no need to specify it when calling config_search(); that specification is meant only to disambiguate which interface attribute (which is a proxy for "what kind of attach args are being used") is having children attached. cfparent_match() will take care of ensuring that any potential children can attach to one of the parent's iterface attributes, and if the parent only carries one, no disambiguation is necessary.
1.81.10.1	20-Mar-2021	thorpej	The proliferation if config_search_() and config_found_() combinations is a little absurd, so begin to tidy this up: - Introduce a new cfarg_t enumerated type, that defines the types of tag-value variadic arguments that can be passed to the various config_() functions (CFARG_SUBMATCH, CFARG_IATTR, and CFARG_LOCATORS, for now, plus a CFARG_EOL sentinel). - Collapse config_search_() into config_search() that takes these variadic arguments. - Convert all call sites of config_search_*() to the new signature. Noticed several incorrect usages along the way, which will be audited in a future commit.

1.63	07-Aug-2021	thorpej	Merge thorpej-cfargs2.
1.62	24-Apr-2021	thorpej	branches: 1.62.8; Merge thorpej-cfargs branch: Simplify and make extensible the config_search() / config_found() / config_attach() interfaces: rather than having different variants for which arguments you want pass along, just have a single call that takes a variadic list of tag-value arguments. Adjust all call sites: - Simplify wherever possible; don't pass along arguments that aren't actually needed. - Don't be explicit about what interface attribute is attaching if the device only has one. (More simplification.) - Add a config_probe() function to be used in indirect configuiration situations, making is visibly easier to see when indirect config is in play, and allowing for future change in semantics. (As of now, this is just a wrapper around config_match(), but that is an implementation detail.) Remove unnecessary or redundant interface attributes where they're not needed. There are currently 5 "cfargs" defined: - CFARG_SUBMATCH (submatch function for direct config) - CFARG_SEARCH (search function for indirect config) - CFARG_IATTR (interface attribte) - CFARG_LOCATORS (locators array) - CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles) ...and a sentinel value CFARG_EOL. Add some extra sanity checking to ensure that interface attributes aren't ambiguous. Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark ports to associate those device handles with device_t instance. This will trickle trough to more places over time (need back-end for pre-OFW Sun OBP; any others?).

1.21	27-Aug-1996	cgd	change cfprint_t type definition to take a const char , rather than a char , because that's what was really intended, and because if the print function modifies the string, various things could become unhappy (so the string should _not_ be modified).
1.20	20-Aug-1996	ragge	Use the same device driver for both uda and mtc. Actually, the only difference is vcid. The unit names must differ, so that it is possible to distinguish them at autoconf time.

1.14	07-Mar-1996	ragge	Support for VAX 8600/8650 added. Works with lots of Unibus adapters, and will probably work with Massbus adapters as well. (Not tested, but it's the same code as for 11/780). Ubareset's may cause crashes on 8600 also like 11/780, but they are more uncommon. No support for console RL02 yet, but it's likely to come.
1.13	02-Mar-1996	ragge	Fix some too long delays. Set some structs volatile that otherwise caused hangs during autoconfig.
1.12	11-Feb-1996	ragge	register -> volatile in some places, to make it work OK with -O2.

1.61.26.1	21-Mar-2021	thorpej	Give config_found() the same variadic arguments treatment as config_search(). This commit only adds the CFARG_EOL sentinel to the existing config_found() calls. Conversion of config_found_sm_loc() and config_found_ia() call sites will be in subsequent commits.
1.62.8.1	04-Aug-2021	thorpej	Adapt to CFARGS().
