 1.126  29-Jun-2024  riastradh if_stats(9): Add ifp argument to if_stat..._ref.

This will enable us to pass the ifp through to a dtrace probe inside.

No functional change intended in this change, but this is an API
change visible to modules so it shouldn't be pulled up.

 1.118  22-Dec-2019  thorpej branches: 1.118.2;
Cleanup i2c bus acquire / release, centralizing all of the logic into
iic_acquire_bus() / iic_release_bus(). "acquire" and "release" hooks
no longer need to be provided by back-end controller drivers (only if
they need special handling, e.g. powering on the i2c controller).
This results in the removal of a bunch of rendundant code from each
back-end controller driver.

Assert that we are not in hard interrupt context in iic_acquire_bus(),
iic_exec(), and iic_release_bus().
 1.117  30-Oct-2019  msaitoh if_percpuq(9) automatically increments if_ipackets, so don't add number of
RX frames from device's statistics counter to if_ipackets to avoid double
count.

 1.113  24-Apr-2019  msaitoh Remove extra test of SIOCSIFMEDIA.
 1.112  05-Feb-2019  msaitoh Remove very old IFF_NOTRAILERS flag.
 1.111  22-Jan-2019  msaitoh Change MII PHY read/write API from:

int (*mii_readreg_t)(device_t, int, int);
void (*mii_writereg_t)(device_t, int, int, int);
to:

int (*mii_readreg_t)(device_t, int, int, uint16_t *);
int (*mii_writereg_t)(device_t, int, int, uint16_t);

Now we can test if a read/write operation failed or not by the return value.

In 802.3 spec says that the PHY shall not respond to read/write transaction
to the unimplemented register(22.2.4.3). Detecting timeout can be used to
check whether a register is implemented or not (if the register conforms to
the spec). ukphy(4) can be used this for MII_MMDACR and MII_MMDAADR.

Note that I noticed that the following code do infinite loop in the
read/wirte function. If it accesses unimplemented PHY register, it will hang.
It should be fixed:

 1.109  26-Jun-2018  msaitoh branches: 1.109.2;
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.
 1.108  22-Jun-2018  msaitoh It's not required to include net/bpfdesc.h. Remove it.
 1.107  23-May-2017  ozaki-r branches: 1.107.2; 1.107.8;
Apply deferred if_start to more drivers

And annotate some XXX_start as it runs in softint to clarify that
it doesn't need deferred if_start.
 1.106  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
 1.105  07-Jul-2016  msaitoh branches: 1.105.2;
KNF. Remove extra spaces. No functional change.
 1.104  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.
 1.103  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@:

 1.97  02-Feb-2012  tls Entropy-pool implementation move and cleanup.

1) Move core entropy-pool code and source/sink/sample management code
to sys/kern from sys/dev.

2) Remove use of NRND as test for presence of entropy-pool code throughout
source tree.

3) Remove use of RND_ENABLED in device drivers as microoptimization to
avoid expensive operations on disabled entropy sources; make the
rnd_add calls do this directly so all callers benefit.

4) Fix bug in recent rnd_add_data()/rnd_add_uint32() changes that might
have lead to slight entropy overestimation for some sources.

5) Add new source types for environmental sensors, power sensors, VM
system events, and skew between clocks, with a sample implementation
for each.

ok releng to go in before the branch due to the difficulty of later
pullup (widespread #ifdef removal and moved files). Tested with release
builds on amd64 and evbarm and live testing on amd64.

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.

Make many ethernet drivers share the common code for MII media
handling, ether_mediastatus() and ether_mediachange(). Check for
a non-ENXIO error return from mii_mediachg(). (ENXIO indicates
that a PHY is suspended.)

This patch shrinks the source code size by 979 lines. There was
a 5100-byte savings on the NetBSD/i386 kernel configuration, ALL.

I have made a few miscellaneous changes, too:

gem(4): use LIST_EMPTY(), LIST_FOREACH().
mtd(4): handle media ioctls, for a change!
axe(4): do not track link status in sc->axe_link any longer
nfe(4), aue(4), axe(4), udav(4), url(4): do not reset all PHYs
on a change of media

Except for the change to mtd(4), no functional changes are intended.

XXX This patch affects more architectures than I can feasibly
XXX compile and run. I have compiled macppc, sparc64, i386. I
XXX have run the patches on i386 boxen with bnx(4) and sip(4).
XXX Compiling and running on evbmips (MERAKI, ADM5120) is in

Change pci_intr_map to get interrupt source information from a "struct
pci_attach_args *" instead of from four separate parameters which in
all cases were extracted from the same "struct pci_attach_args".

This both simplifies the driver api, and allows for alternate PCI
interrupt mapping schemes, such as one using the tables described in
the Intel Multiprocessor Spec which describe interrupt wirings for
devices behind pci-pci bridges based on the device's location rather
the bridge's location.

 1.20  18-Aug-1998  thorpej vm_offset_t -> vaddr_t
 1.19  15-Aug-1998  thorpej Oops, don't forget to tick the MII once a second.
 1.18  15-Aug-1998  bouyer Fix typos in last commit.
 1.17  15-Aug-1998  bouyer correct indent.
 1.16  13-Aug-1998  eeh Merge paddr_t changes into the main branch.
 1.15  11-Aug-1998  thorpej Adapt to the new MII code. This required splitting some structures into
if_tlvar.h, since the ThunderLAN PHY driver needs to know some things
about it's parent (and since it can only attach to a ThunderLAN chip,
this is the easiest way).
 1.14  08-Aug-1998  mycroft Use splnet, not splimp.
 1.13  05-Jul-1998  jonathan branches: 1.13.2;
defopt NS, NSIP.
 1.12  05-Jul-1998  jonathan defopt INET, NETATALK.
 1.11  08-Jun-1998  thorpej Nuke __BROKEN_INDIRECT_CONFIG.
 1.10  05-May-1998  thorpej Slighly less brutal hack to deal with broken memory-mapped access of
the ThunderLAN on the TI TravelMate 5000 docking station: single it out,
and allow memory-mapped access on the Compaq products.
 1.9  11-Feb-1998  bouyer Correct a bogosity in the adapter->mii attach code pointed out by cgd:
in pci/if_tl.c, call config_found() with a print function, instead of
printing ourself a message in if_tl.c if no miibus was found. The print
function is in mii/mii.c (mii_adapter_print()) so that it can be used by any
adapter (idea from the scsi system).
 1.8  12-Jan-1998  thorpej Update for config changes.
 1.7  30-Nov-1997  drochner make it compile without "__BROKEN_INDIRECT_CONFIG"
 1.6  18-Nov-1997  bouyer Fix for systems with multiple tl interfaces:
nullbuf (used to pad packets < ETHER_MIN_SIZE) is used for all tl
interfaces. Allocates only once, and never deallocate it (as we can't say
if another instance of the driver is interface is using it).
 1.5  17-Nov-1997  thorpej Sigh, now that we've fixed a bug in PCI space management (the bug caused
i/o-mapped space to always be used), we discover that at least one
ThunderLAN interface can't read the EEPROM properly if memory-mapped
access is used. Kludge around this for now by "prefering" i/o space.
 1.4  17-Nov-1997  thorpej Fix a couple of bugs/annoyances in match/attach:
- Do PCI space configuration like the other drivers. In particular,
don't _disable_ the space we're not using because some lame firmware
implementations might not reenable it on warm boot. Also, prefer
memory space always.
- Make match and info-gathering in attach table-driven.
- Rearrange things a bit to be a bit more visually pleasing during boot.

Also, fixup some #include problems.
 1.3  16-Nov-1997  christos PR/4510: William Coldwell: Add TI thunderlan support.

Driver for Texas Instruments' thunderland network controller (present in some
Compaq products).
 1.1.2.5  10-Nov-1998  cgd patch from bouyer to address sysinst and media selection issues:
set the default media to UTP, and don't include 'none' in the media
list, so that sysinst will be able to set media properly. Done
differently in -current, because there the code uses MII. (bouyer)

5) Make entropy harvesting from environmental sensors a little more generic
and remove it from individual sensor drivers.
