driver probe list
Enabling interrupts via device tree for the internal PHYs on the
mv88e6390 DSA switch does not work. The driver insists to use poll mode.
Stage one debugging shows that the fwnode_mdiobus_phy_device_register
function calls fwnode_irq_get properly, and phy->irq is set to a valid
interrupt line initially.
But it is then cleared.
Stage two debugging shows that it is cleared here:
phy_probe:
/* Disable the interrupt if the PHY doesn't support it
* but the interrupt is still a valid one
*/
if (!phy_drv_supports_irq(phydrv) && phy_interrupt_is_valid(phydev))
phydev->irq = PHY_POLL;
Okay, so does the "Marvell 88E6390 Family" PHY driver not have the
.config_intr and .handle_interrupt function pointers? Yes it does.
Stage three debugging shows that the PHY device does not attempt a probe
against the "Marvell 88E6390 Family" driver, but against the "mv88x3310"
driver.
Okay, so why does the "mv88x3310" driver match on a mv88x6390 internal
PHY? The PHY IDs (MARVELL_PHY_ID_88E6390_FAMILY vs
MARVELL_PHY_ID_88X3310) are way different.
Stage four debugging has us looking through:
phy_device_register
-> device_add
-> bus_probe_device
-> device_initial_probe
-> __device_attach
-> bus_for_each_drv
-> driver_match_device
-> drv->bus->match
-> phy_bus_match
Okay, so as we said, the MII_PHYSID1 of mv88e6390 does not match the
mv88x3310 driver's PHY mask & ID, so why would phy_bus_match return...
Ahh, phy_bus_match calls a shortcircuit method,
phydrv->match_phy_device, and does not even bother to compare the PHY ID
if that is implemented.
So of course, we go inside the marvell10g.c driver and sure enough, it
implements .match_phy_device and does not bother to check the PHY ID.
What's interesting though is that at the end of the device_add() from
phy_device_register(), the driver for the internal PHYs _is_ the proper
"Marvell 88E6390 Family". This is because "mv88x3310" ends up failing to
probe after all, and __device_attach_driver(), to quote:
/*
* Ignore errors returned by ->probe so that the next driver can try
* its luck.
*/
The next (and only other) driver that matches is the 6390 driver. For
this one, phy_probe doesn't fail, and everything expects to work as
normal, EXCEPT phydev->irq has already been cleared by the previous
unsuccessful probe of a driver which did not implement PHY interrupts,
and therefore cleared that IRQ.
Okay, so it is not just Marvell 6390 that has PHY interrupts broken.
Stuff like Atheros, Aquantia, Broadcom, Qualcomm work because they are
lexicographically before Marvell, and stuff like NXP, Realtek, Vitesse
are broken.
This goes to show how fragile it is to reset phydev->irq = PHY_POLL from
the actual beginning of phy_probe itself. That seems like an actual bug
of its own too, since phy_probe has side effects which are not restored
on probe failure, but the line of thought probably was, the same driver
will attempt probe again, so it doesn't matter. Well, looks like it
does.
Maybe it would make more sense to move the phydev->irq clearing after
the actual device_add() in phy_device_register() completes, and the
bound driver is the actual final one.
(also, a bit frightening that drivers are permitted to bypass the MDIO
bus matching in such a trivial way and perform PHY reads and writes from
the .match_phy_device method, on devices that do not even belong to
them. In the general case it might not be guaranteed that the MDIO
accesses one driver needs to make to figure out whether to match on a
device is safe for all other PHY devices)

bnxt may discard packets if Rx completions are consumed
in an attempt to let netpoll make progress. It should be
extremely rare in practice but nonetheless such events
should be counted.
Since completion ring memory is allocated dynamically use
a similar scheme to what is done for HW stats to save them.
Report the stats in rx_dropped and per-netdev ethtool
counter. Chances that users care which ring dropped are
very low.
v3: only save the stat to rx_dropped on reset,
rx_total_netpoll_discards will now only show drops since
last reset, similar to other "total_discard" counters.

The recursion protection for eventfd_signal() is based on a per CPU
variable and relies on the !RT semantics of spin_lock_irqsave() for
protecting this per CPU variable. On RT kernels spin_lock_irqsave() neither
disables preemption nor interrupts which allows the spin lock held section
to be preempted. If the preempting task invokes eventfd_signal() as well,
then the recursion warning triggers.
Paolo suggested to protect the per CPU variable with a local lock, but
that's heavyweight and actually not necessary. The goal of this protection
is to prevent the task stack from overflowing, which can be achieved with a
per task recursion protection as well.
Replace the per CPU variable with a per task bit similar to other recursion
protection bits like task_struct::in_page_owner. This works on both !RT and
RT kernels and removes as a side effect the extra per CPU storage.
No functional change for !RT kernels.

After trunking is discovered in nfs4_discover_server_trunking(),
add the transport to the old client structure if the allowed limit
of transports has not been reached.
An example: there exists a multi-homed server and client mounts
one server address and some volume and then doest another mount to
a different address of the same server and perhaps a different
volume. Previously, the client checks that this is a session
trunkable servers (same server), and removes the newly created
client structure along with its transport. Now, the client
adds the connection from the 2nd mount into the xprt switch of
the existing client (it leads to having 2 available connections).

This option will control up to how many xprts can the client
establish to the server with a distinct address (that means
nconnect connections are not counted towards this new limit).
This patch is setting up nfs structures to keeep track of the
max_connect limit (does not enforce it).
The default value is kept at 1 so that no current mounts that
don't want any additional connections would be effected. The
maximum value is set at 16.
Mounts to DS are not limited to default value of 1 but instead
set to the maximum default value of 16 (NFS_MAX_TRANSPORTS).

We only really need to call shutdown() if we're in the ESTABLISHED TCP
state, since that is the only case where the client is initiating a
close of an established connection.
If the socket is in FIN_WAIT1 or FIN_WAIT2, then we've already initiated
socket shutdown and are waiting for the server's reply, so do nothing.
In all other cases where we've already received a FIN from the server,
we should be able to just close the socket.

The recent change for low latency playback works in most of test cases
but it turned out still to hit errors on some use cases, most notably
with JACK with small buffer sizes. This is because USB-audio driver
fills up and submits full URBs at the beginning, while the URBs would
return immediately and try to fill more -- that can easily trigger
XRUN. It was more or less expected, but in the small buffer size, the
problem became pretty obvious.
Fixing this behavior properly would require the change of the
fundamental driver design, so it's no trivial task, unfortunately.
Instead, here we work around the problem just by switching back to the
old method when the given configuration is too fragile with the low
latency stream handling. As a threshold, we calculate the total
buffer bytes in all plus one URBs, and check whether it's beyond the
PCM buffer bytes. The one extra URB is needed because XRUN happens at
the next submission after the first round.

commit 3ba7f53f8bf1 ("ice: don't remove netdev->dev_addr from uc sync
list") introduced calls to netif_addr_lock_bh() and
netif_addr_unlock_bh() in the driver's ndo_set_mac() callback. This is
fine since the driver is updated the netdev's dev_addr, but since this
is a spinlock, the driver cannot sleep when the lock is held.
Unfortunately the functions to add/delete MAC filters depend on a mutex.
This was causing a trace with the lock debug kernel config options
enabled when changing the mac address via iproute.

When we enabled auxiliary input/output support for the E810 device, we
forgot to add logic to restart the output when we change time. This is
important as the periodic output will be incorrect after a time change
otherwise.
This unfortunately includes the adjust time function, even though it
uses an atomic hardware interface. The atomic adjustment can still cause
the pin output to stall permanently, so we need to stop and restart it.
Introduce wrapper functions to temporarily disable and then re-enable
the clock outputs.

This should be reverted in the char-misc-next branch to make merging
with Linus's branch possible due to issues with the mhi code that was
found in the networking tree.

While in practice vcpu->vcpu_idx == vcpu->vcp_id is often true, it may
not always be, and we must not rely on this. Reason is that KVM decides
the vcpu_idx, userspace decides the vcpu_id, thus the two might not
match.
Currently kvm->arch.idle_mask is indexed by vcpu_id, which implies
that code like
for_each_set_bit(vcpu_id, kvm->arch.idle_mask, online_vcpus) {
vcpu = kvm_get_vcpu(kvm, vcpu_id);
do_stuff(vcpu);
}
is not legit. Reason is that kvm_get_vcpu expects an vcpu_idx, not an
vcpu_id. The trouble is, we do actually use kvm->arch.idle_mask like
this. To fix this problem we have two options. Either use
kvm_get_vcpu_by_id(vcpu_id), which would loop to find the right vcpu_id,
or switch to indexing via vcpu_idx. The latter is preferable for obvious
reasons.
Let us make switch from indexing kvm->arch.idle_mask by vcpu_id to
indexing it by vcpu_idx. To keep gisa_int.kicked_mask indexed by the
same index as idle_mask lets make the same change for it as well.

When this feature is enabled the hardware is free to interpret
specification exceptions generated by the guest, instead of causing
program interruption interceptions.
This benefits (test) programs that generate a lot of specification
exceptions (roughly 4x increase in exceptions/sec).
Interceptions will occur as before if ICTL_PINT is set,
i.e. if guest debug is enabled.
There is no indication if this feature is available or not and the
hardware is free to interpret or not. So we can simply set this bit and
if the hardware ignores it we fall back to intercept 8 handling.

Implement support for Credit-based shaper(CBS) Qdisc hardware
offload mode in the driver. There are two sets of IEEE802.1Qav
(CBS) HW logic in i225 controller and this patch supports
enabling them in the top two priority TX queues.
Driver implemented as recommended by Foxville External
Architecture Specification v0.993. Idleslope and Hi-credit are
the CBS tunable parameters for i225 NIC, programmed in TQAVCC
and TQAVHC registers respectively.
In-order for IEEE802.1Qav (CBS) algorithm to work as intended
and provide BW reservation CBS should be enabled in highest
priority queue first. If we enable CBS on any of low priority
queues, the traffic in high priority queue does not allow low
priority queue to be selected for transmission and bandwidth
reservation is not guaranteed.

Separates the procedure done during reset from applying a

separate the better what changes the hardware state from what
changes only the driver state.
Introduces a flag for bookkeeping the driver state of TSN
features. When Qav and frame-preemption is also implemented
this flag makes it easier to keep track on whether a TSN feature
driver state is enabled or not though controller state changes,
say, during a reset.
