We refactor the complete handler since the return path with the
locking are really difficult to follow. Just simplify the function by
switching the logic return it on an disabled endpoint early. This way
the second level of indentation can be removed.

The pump function is running in an while(1) loop. The only case this
loop will be escaped is the two breaks. In both cases the req is valid.
Therefor the check for an not set req can be dropped and setting the req
to NULL does also has never any effect.

The USB role switch does not always have the _PLD (Physical
Location of Device) in ACPI tables. If it's missing,
assigning the PLD hash of the port to the switch. That
should guarantee that the USB Type-C port mapping code is
always able to find the connection between the two (the port
and the switch).

This is probable useful information to have in user space in
general, but it's primarily needed for the xHCI DbC (Debug
Capability). When xHCI DbC is being used, the USB port needs
to be muxed to the xHCI even in device role. In xHCI DbC mode,
the xHCI is the USB device controller.

Add PHY2 register space to DT binding documentation.

So far this register space was not required but due to the

This patch introduces three new ioctls. They all should be called on a
data endpoint (ie. not ep0). They are:
- FUNCTIONFS_DMABUF_ATTACH, which takes the file descriptor of a DMABUF
object to attach to the endpoint.
- FUNCTIONFS_DMABUF_DETACH, which takes the file descriptor of the
DMABUF to detach from the endpoint. Note that closing the endpoint's
file descriptor will automatically detach all attached DMABUFs.
- FUNCTIONFS_DMABUF_TRANSFER, which requests a data transfer from / to
the given DMABUF. Its argument is a structure that packs the DMABUF's
file descriptor, the size in bytes to transfer (which should generally
be set to the size of the DMABUF), and a 'flags' field which is unused
for now.
Before this ioctl can be used, the related DMABUF must be attached
with FUNCTIONFS_DMABUF_ATTACH.
These three ioctls enable the FunctionFS code to transfer data between
the USB stack and a DMABUF object, which can be provided by a driver
from a completely different subsystem, in a zero-copy fashion.

The driver dwc3 deviates from the programming guide in regard to
endpoint configuration. It does this command sequence:
DEPSTARTCFG -> DEPXFERCFG -> DEPCFG
Instead of the suggested flow:
DEPSTARTCFG -> DEPCFG -> DEPXFERCFG
The reasons for this deviation were as follow, quoted:
1) The databook says to do %DWC3_DEPCMD_DEPSTARTCFG for every
%USB_REQ_SET_CONFIGURATION and %USB_REQ_SET_INTERFACE
(8.1.5). This is incorrect in the scenario of multiple
interfaces.
2) The databook does not mention doing more
%DWC3_DEPCMD_DEPXFERCFG for new endpoint on alt setting
(8.1.6).
Regarding 1), DEPSTARTCFG resets the endpoints' resource and can be a
problem if used with SET_INTERFACE request of a multiple interface
configuration. But we can still satisfy the programming guide
requirement by assigning the endpoint resource as part of
usb_ep_enable(). We will only reset endpoint resources on controller
initialization and SET_CONFIGURATION request.
Regarding 2), the later versions of the programming guide were updated
to clarify this flow (see "Alternate Initialization on SetInterface
Request" of the programming guide). As long as the platform has enough
physical endpoints, we can assign resource to a new endpoint.
The order of the command sequence will not be a problem to most
platforms for the current implementation of the dwc3 driver. However,
this order is required in different scenarios (such as initialization
during controller's hibernation restore). Let's keep the flow consistent
and follow the programming guide.

The event ring dequeue pointer field (ERDP) in xHC hardware is used to
inform controller how far the driver has processed events on the event
ring.
In the case all events are handled and event ring is empty then the
address of the TRB after the last processed one should be written.
This TRB is both the enqueue and dequeue pointer.
But in case we are writing the ERDP in the middle of processing
several events then ERDP field should be written with the "up to and
including" address of the last handled event TRB.
Currenly each ERDP write by driver is done as if all events are handled
and ring is empty.
Fix this by adjusting the order when software dequeue "inc_deq()"
is called and hardware dequeue "xhci_update_erst_dequeue()" is updated.
Details in xhci 1.2 specification section 4.9.4:
"System software shall write the Event Ring Dequeue Pointer (ERDP)
register to inform the xHC that it has completed the processing of Event
TRBs up to and including the Event TRB referenced by the ERDP.
The detection of a Cycle bit mismatch in an Event TRB processed by
software indicates the location of the xHC Event Ring Enqueue Pointer
and that the Event Ring is empty. Software shall write the ERDP with
the address of this TRB to indicate that it has processed all Events
in the ring"
This change depends on fixes made to relocate inc_deq() calls captured
in the below commits:
commit 3321f84bfae0 ("xhci: simplify event ring dequeue tracking for
transfer events")
commit d1830364e963 ("xhci: Simplify event ring dequeue pointer update
for port change events")

The event_ring_deq parameter is used to check if the event ring dequeue
position is updated while calling by xhci_handle_event(), meaning there was
an actual event on the ring to handle. In this case the driver needs to
inform hardware about the updated dequeue position.
Basically event_ring_deq just stores the old event ring dequeue position
before calling the event handler.
Keeping track of software event dequeue updates this way is no longer
useful as driver anyways reads the current hardware dequeue position
within the handle event, and checks if it needs to be updated.
The driver might anyway need to modify the EHB (event handler busy) bit in
the same register as the dequeue pointer even if the actual dequeue
position did not change.

isoc_bei_interval is used to balance how often completed isochronous
events cause interrupts. If interval is too large then the event ring
may fill up before the completed isoc TRBs are handled.
isoc_bei_interval is tuned based on how full the event ring is.
isoc_bei_interval variable needs to be per interrupter as
with several interrupters each one has its own event ring.

Each interrupter has an interrupt pending (IP) bit that should be cleared
in the interrupt handler. This is done automatically for systems using
MSI/MSI-X interrupts.
Secondary interrupters used by audio offload may not actually trigger
MSI/MSI-X messages, so driver may need to clear the IP bit manually for
these, even if the primary interrupter IP is cleared automatically.
Add an ip_autoclear flag to each interrupter that driver can configure
when requesting an interrupt for that xHC interrupter, and move
the interrupt pending clearing code to its own helper function.
Use this ip_autoclear flag instead of the current hcd->msi_enabled
to check if IP flag is cleared by software.
[Moved ip_autoclear into xhci and set based on msi_enabled -wcheng]

"Vendor events:
- Intel Alderlake/Sapphire Rapids metric fixes, the CPU type
("cpu_atom", "cpu_core") needs to be used as a prefix to be
considered on a metric formula, detected via one of the 'perf test'
entries.
'perf test' fixes:
- Fix the creation of event selector lists on 'perf test' entries, by
initializing the sample ID flag, which is done by 'perf record', so
this fix affects only the tests, the common case isn't affected
- Make 'perf list' respect debug settings (-v) to fix its 'perf test'
entry
- Fix 'perf script' test when python support isn't enabled
- Special case 'perf script' tests on s390, where only DWARF call
graphs are supported and only on software events
- Make 'perf daemon' signal test less racy
Compiler warnings/errors:
- Remove needless malloc(0) call in 'perf top' that triggers
-Walloc-size
- Fix calloc() argument order to address error introduced in gcc-14
Build:
- Make minimal shellcheck version to v0.6.0, avoiding the build to
fail with older versions
Sync kernel header copies:
- stat.h to pick STATX_MNT_ID_UNIQUE
- msr-index.h to pick IA32_MKTME_KEYID_PARTITIONING
- drm.h to pick DRM_IOCTL_MODE_CLOSEFB
- unistd.h to pick {list,stat}mount,
lsm_{[gs]et_self_attr,list_modules} syscall numbers

Pull tracing and eventfs fixes from Steven Rostedt:
- Fix the return code for ring_buffer_poll_wait()
It was returing a -EINVAL instead of EPOLLERR.
- Zero out the tracefs_inode so that all fields are initialized.
The ti->private could have had stale data, but instead of just
initializing it to NULL, clear out the entire structure when it is
allocated.
- Fix a crash in timerlat
The hrtimer was initialized at read and not open, but is canceled at
close. If the file was opened and never read the close will pass a
NULL pointer to hrtime_cancel().
- Rewrite of eventfs.
Linus wrote a patch series to remove the dentry references in the
eventfs_inode and to use ref counting and more of proper VFS
interfaces to make it work.
- Add warning to put_ei() if ei is not set to free. That means
something is about to free it when it shouldn't.
- Restructure the eventfs_inode to make it more compact, and remove the
unused llist field.
- Remove the fsnotify*() funtions for when the inodes were being
created in the lookup code. It doesn't make sense to notify about
creation just because something is being looked up.
- The inode hard link count was not accurate.
It was being updated when a file was looked up. The inodes of
directories were updating their parent inode hard link count every
time the inode was created. That means if memory reclaim cleaned a
stale directory inode and the inode was lookup up again, it would
increment the parent inode again as well. Al Viro said to just have
all eventfs directories have a hard link count of 1. That tells user
space not to trust it.
