There is a 120ms delay implemented for allowing the XHCI host controller to
detect a U3 wakeup pulse. The intention is to wait for the device to retry
the wakeup event if the USB3 PORTSC doesn't reflect the RESUME link status
by the time it is checked. As per the USB3 specification:
tU3WakeupRetryDelay ("Table 7-12. LTSSM State Transition Timeouts")
This would allow the XHCI resume sequence to determine if the root hub
needs to be also resumed. However, in case there is no device connected,
or if there is only a HSUSB device connected, this delay would still affect
the overall resume timing.
Since this delay is solely for detecting U3 wake events (USB3 specific)
then ignore this delay for the disconnected case and the HSUSB connected
only case.

If this driver enables the xHC clocks while resuming from sleep, it calls
clk_prepare_enable() without checking for errors and blithely goes on to
read/write the xHC's registers -- which, with the xHC not being clocked,
at least on ARM32 usually causes an imprecise external abort exceptions
which cause kernel oops. Currently, the chips for which the driver does
the clock dance on suspend/resume seem to be the Broadcom STB SoCs, based
on ARM32 CPUs, as it seems...

In some situations where xhci removal happens parallel to xhci_handshake,
we encounter a scenario where the xhci_handshake can't succeed, and it
polls until timeout.
If xhci_handshake runs until timeout it can on some platforms result in
a long wait which might lead to a watchdog timeout.
Add a helper that checks xhci status during the handshake, and exits if
set state is entered. Use this helper in places where xhci_handshake is
called unlocked and has a long timeout. For example xhci command timeout
and xhci reset.

The current function that both removes and frees an interrupter isn't
optimal when using several interrupters. The array of interrupters need
to be protected with a lock while removing interrupters, but the default
xhci spin lock can't be used while freeing the interrupters event ring
segment table as dma_free_coherent() should be called with IRQs enabled.
There is no need to free the interrupter under the lock, so split this
code into separate unlocked free part, and a lock protected remove part.

Use the low-power states of the underlying platform to enable runtime PM.
If the platform doesn't support runtime D3, then enabling default RPM will

The AMD USB host controller (1022:43f7) isn't going into PCI D3 by default
without anything connected. This is because the policy that was introduced
by commit a611bf473d ("xhci-pci: Set runtime PM as default policy on all
xHC 1.2 or later devices") only covered 1.2 or later.
The 1.1 specification also has the same requirement as the 1.2
specification for D3 support. So expand the runtime PM as default policy
to all AMD 1.1 devices as well.

Increase the event ring dequeue pointer for port change events in the
same way as other event types. No need to handle it separately.
This only touches the driver side tracking of event ring dequeue.
Note: this does move forward the event ring dequeue increase for port
change events a bit.
Previously the dequeue was increased before temporarily dropping
the xhci lock while kicking roothub polling.
Now dequeue is increased after re-aquiring the lock.
This should not matter as event ring dequeue is not touched at all by
hub thread. It's only touched in xhci interrupt handler.

No matter what type of event we receive we want to increase the event
ring dequeue pointer one step for every event that is handled.
For unknown reasons the event ring dequeue increase is done inside the
transfer event handler and port event handler.
As the transfer event handler got more complex and can now loop through
several transfer TRBs on a transfer ring, there were additinal checks
added to avoid increasing event ring dequeue more than one step.
No need for elaborate checks to avoid increasing event ring dequeue
in case the transfer event handler goes through a loop.
Just increasing the event ring dequeue outside the transfer event
handler.
End goal is to increase event ring dequeue in just one place.

Initial xhci_ring allocation has just been amended to assign a

However rings may be expanded after initial allocation.
So number newly inserted segments starting from the preceding segment in
the ring and renumber all segments succeeding the newly inserted ones.
This is not a fix because ring expansion currently isn't done on the
Event Ring and that's the only ring type using the segment number.

Users have reported log spam created by "Event Ring Full" xHC event
TRBs. These are caused by interrupt latency in conjunction with a very
busy set of devices on the bus. The errors are benign, but throughput
will suffer as the xHC will pause processing of transfers until the
Event Ring is drained by the kernel.
Commit dc0ffbea57 ("usb: host: xhci: update event ring dequeue pointer
on purpose") mitigated the issue by advancing the Event Ring Dequeue
Pointer already after half a segment has been processed. Nevertheless,
providing a larger Event Ring would be useful to cope with load peaks.
Expand the number of event TRB slots available by increasing the number
of Event Ring segments in the ERST.
Controllers have a hardware-defined limit as to the number of ERST
entries they can process, but with up to 32k it can be excessively high
(sec 5.3.4). So cap the actual number at 2 (configurable through the
ERST_MAX_SEGS macro), which seems like a reasonable quantity. It is
supported by any xHC because the limit in the HCSPARAMS2 register is
defined as a power of 2. Renesas uPD720201 and VIA VL805 controllers
do not support more than 2 ERST entries.
An alternative to increasing the number of Event Ring segments would be
an increase of the segment size. But that requires allocating multiple
contiguous pages, which may be impossible if memory is fragmented.

When using more than one Event Ring segment (ERSTSZ > 1), software shall
set the DESI bits in the ERDP register to the number of the segment to
which the upper ERDP bits are pointing. The xHC may use the DESI bits
as a shortcut to determine whether it needs to check for an Event Ring
Full condition: If it's enqueueing events in a different segment, it
need not compare its internal Enqueue Pointer with the Dequeue Pointer
in the upper bits of the ERDP register (sec 5.5.2.3.3).
Not setting the DESI bits correctly can result in the xHC enqueueing
events past the Dequeue Pointer. On Renesas uPD720201 host controllers,
incorrect DESI bits cause an interrupt storm. For comparison, VIA VL805
host controllers do not exhibit such problems. Perhaps they do not take
advantage of the optimization afforded by the DESI bits.
To fix the issue, assign the segment number to each struct xhci_segment
in xhci_segment_alloc(). When advancing the Dequeue Pointer in
xhci_update_erst_dequeue(), write the segment number to the DESI bits.
On driver probe, set the DESI bits to zero in xhci_set_hc_event_deq() as
processing starts in segment 0. Likewise on driver teardown, clear the
DESI bits to zero in xhci_free_interrupter() when clearing the upper
bits of the ERDP register. Previously those functions (incorrectly)
treated the DESI bits as if they're declared RsvdP.

The next_trb() helper relies on a link TRB at the end of a ring segment
to know a segment ends. This works well with transfer rings that use
link trbs, but not with event rings.
Event rings segments are always filled by host to segment size
before moving to next segment. It does not use link TRBs
Check for both link trb and full segment in next_trb() helper to
support event rings.

b1472a60a5 ("x86/smp: Don't send INIT to boot CPU")

some Dell machines, but Thomas says
"The rest seems to be Lenovo and Sony with Alderlake/Raptorlake CPUs -
at least that's what I could figure out from the various bug reports.
I don't know which CPUs the DELL machines have, so I can't say it's a
pattern.
I agree with the revert for now"
Ashok Raj chimes in:
"There was a report (probably this same one), and it turns out it was a
bug in the BIOS SMI handler.
The client BIOS's were waiting for the lowest APICID to be the SMI
rendevous master. If this is MeteorLake, the BSP wasn't the one with
the lowest APIC and it triped here.
The BIOS change is also being pushed to others for assimilation :)
Server BIOS's had this correctly for a while now"
and it does look likely to be some bad interaction between SMI and the
non-BSP cores having put into INIT (and thus unresponsive until reset).

Kernel v6.5 converted overlayfs to new mount api.
As an added bonus, it also added a feature to allow appending lowerdirs
using lowerdir=:/lower2,lowerdir=::/data3 syntax.
This new syntax has raised some concerns regarding escaping of colons.
We decided to try and disable this syntax, which hasn't been in the wild
for so long and introduce it again in 6.7 using explicit mount options
lowerdir+=/lower2,datadir+=/data3.

Before commit b36a5780cb ("ovl: modify layer parameter parsing"),
spaces and commas in lowerdir mount option value used to be escaped using
seq_show_option().
In current upstream, when lowerdir value has a space, it is not escaped
in /proc/mounts, e.g.:
none /mnt overlay rw,relatime,lowerdir=l l,upperdir=u,workdir=w 0 0
which results in broken output of the mount utility:
none on /mnt type overlay (rw,relatime,lowerdir=l)
Store the original lowerdir mount options before unescaping and show
them using the same escaping used for seq_show_option() in addition to
escaping the colon separator character.

Touch controllers need some time after receiving reset command for the
firmware to finish re-initializing and be ready to respond to commands
from the host. The driver already had handling for the post-reset delay
for I2C and SPI transports, this change adds the handling to
SMBus-connected devices.
SMBus devices are peculiar because they implement legacy PS/2
compatibility mode, so reset is actually issued by psmouse driver on the
associated serio port, after which the control is passed to the RMI4
driver with SMBus companion device.
Note that originally the delay was added to psmouse driver in
92e24e0e57 ("Input: psmouse - add delay when deactivating for SMBus
mode"), but that resulted in an unwanted delay in "fast" reconnect
handler for the serio port, so it was decided to revert the patch and
have the delay being handled in the RMI4 driver, similar to the other
transports.

When the SMBus connection is attempted psmouse_smbus_init() sets
the fast_reconnect pointer to psmouse_smbus_reconnecti(). If SMBus
initialization fails, elantech_setup_ps2() and synaptics_init_ps2() will
fallback to PS/2 mode, replacing the psmouse private data. This can cause
issues on resume, since psmouse_smbus_reconnect() expects to find an
instance of struct psmouse_smbus_dev in psmouse->private.
The issue was uncovered when in 92e24e0e57 ("Input: psmouse - add
delay when deactivating for SMBus mode") psmouse_smbus_reconnect()
started attempting to use more of the data structure. The commit was
since reverted, not because it was at fault, but because there was found
a better way of doing what it was attempting to do.
Fix the problem by resetting the fast_reconnect pointer in psmouse
structure in elantech_setup_ps2() and synaptics_init_ps2() when the PS/2
mode is used.

GM6BG0Q, and for ASUS ExpertBook B1402CBA (Hans de Goede).
* tag 'acpi-6.6-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
ACPI: resource: Add TongFang GM6BGEQ, GM6BG5Q and GM6BG0Q to irq1_edge_low_force_override[]
ACPI: EC: Add quirk for the HP Pavilion Gaming 15-dk1xxx
ACPI: resource: Skip IRQ override on ASUS ExpertBook B1402CBA
* A handful of build fixes.
* A fix to avoid mixing up user/kernel-mode breakpoints, which can
manifest as a hang when mixing k/uprobes with other breakpoint
sources.
* A fix to avoid double-allocting crash kernel memory.
* A fix for tracefs syscall name mangling, which was causing syscalls
not to show up in tracefs.
* A fix to the perf driver to enable the hw events when selected, which
can trigger a BUG on some userspace access patterns.
