The driver notifies the hardware to handle task through
doorbell. Currently, doorbell is enabled by default. To
prevent the process from sending doorbells during hardware
reset scenarios, which could cause the hardware to process
doorbells and trigger new errors:
For example, when the physical machine is resetting the device,
doorbells are still being sent from the virtual machine.
Therefore, the driver disables doorbell during hardware
unavailability. After hardware initialization is completed,
doorbell is enabled, and any task sent during the unavailability
period will return errors.
The hardware supports the PF to disable doorbells for all functions,
while the VF can only disable its own doorbell function. When the PF
is reset, it will disable doorbells for all functions. When VF is
reset, it only disables its own doorbell and does not affect tasks
on other functions.

Each bit in the error interrupt register corresponds to a specific
error type. A bit value of 0 enables the interrupt, and a bit value
of 1 disables the interrupt. Currently, when disabling interrupts,
it incorrectly enables the interrupt types that were not enabled.
Therefore, when disabling interrupts, all bits should be directly
written to 1.

Before function level reset, driver first disable device error report
and then waits for the device reset to complete. However, when the
error is recovered, the error bits will be enabled again, resulting in
invalid disable. It is modified to detect that there is no error
before disable error report, and then do FLR.

When executing operations on crypto devices, hardware errors
are inevitable. For certain errors, a full device reset is
required to recover. However, in certain cases, only a
specific function may fail, while other functions can still
operate normally. A system-wide RAS reset in such cases would
unnecessarily impact functioning components.
This patch introduces function-level granularity handling,
enabling targeted resets of only the error-reporting
functions without affecting other operational functions.

usage counter
To avoid accessing memory of a suspended device, and since the counter
interface used by PM involves sleep operations, the counter interface
cannot be placed in the interrupt top half. Therefore, the interface for
acquiring the interrupt status in the RAS reset flow that resides in the
interrupt context needs to be moved to the bottom half for processing.

The problem that the VF device cannot obtain the isolation
status and isolation threshold of the device is resolved.
The accelerator driver can query the device isolation status
and threshold via the VF device using the fault query sysfs
interface under uacce. Note that only the PF device supports
isolation policy configuration, while the VF device is
limited to read-only query operations.

Split out two new headers from the public pq.h:
- lib/raid/raid6/algos.h contains the algorithm lists private to
lib/raid/raid6
- include/linux/raid/pq_tables.h contains the tables also used by
async_tx providers.
The public include/linux/pq.h is now limited to the public interface for
the consumers of the RAID6 PQ API.

When building vmlinuz.efi with CONFIG_EFI_ZBOOT enabled, '__lshrdi3()'
is also needed to fix yet another link error observed when building
riscv32 and loongarch32 images:
riscv32-linux-gnu-ld: drivers/firmware/efi/libstub/lib-cmdline.stub.o: in function `__efistub_.L49':
__efistub_cmdline.c:(.init.text+0x202): undefined reference to `__efistub___lshrdi3'

__efistub_cmdline.c:(.init.text+0x26c): undefined reference to `__efistub___lshrdi3'
And since both riscv64 and loongarch64 can have CONFIG_EFI_ZBOOT but
doesn't need these library routines, rely on CONFIG_32BIT to manage
linking of lib-ashldi3.o and lib-lshrdi3.o on 32-bit variants only.

With a list_for_each() loop, if we don't find the item we are looking for
in the list, then the loop exits with the iterator, which is "dbell" in
this loop, pointing to invalid memory.
This code uses the "found" variable to determine if we have found the
doorbell we are looking for or not. However, the problem that the "found"
variable needs to be set to false at the start of each iteration,
otherwise after the first correct doorbell, then everything is marked as
found.
Reset the "found" to false at the start of the iteration and move the
variable inside the loop.

Store common handle IDs in "struct kcov_common_handle_id", which consumes
no space in non-KCOV builds.
This cleanup removes #ifdef boilerplate code from subsystems that
integrate with KCOV (in particular in usbip_common.h and skbuff.h, see the
diffstat).
This should also make it easier to add KCOV remote coverage to more
subsystems in the future.

When dev_dax_kmem_probe() partially succeeds (at least one range is
mapped) but a subsequent range fails request_mem_region() or
add_memory_driver_managed(), the probe silently continues, ultimately
returning success, but with the corresponding range resource NULL'ed out.
dev_dax_kmem_remove() iterates over all dax_device ranges regardless of if
the underlying resource exists. When remove_memory() is called later, it
returns 0 because the memory was never added which causes
dev_dax_kmem_remove() to incorrectly assume the (nonexistent) resource can
be removed and attempts cleanup on a NULL pointer.
Fix this by skipping these ranges altogether, noting that these cases are
considered success, such that the cleanup is still reached when all
actually-added ranges are successfully removed.

Commit 8871389da151 introduces common pcs dts properties which writes
rx=normal,tx=normal polarity to register SGMSYS_QPHY_WRAP_CTRL of switch.
This is initialized with tx-bit set and so change inverts polarity
compared to before.
It looks like mt7531 has tx polarity inverted in hardware and set tx-bit
by default to restore the normal polarity.
The MT7531 datasheet quite clearly states:
Register 000050EC QPHY_WRAP_CTRL -- QPHY wrapper control
Reset value: 0x00000501
BIT 1 RX_BIT_POLARITY -- RX bit polarity control
1'b0: normal
1'b1: inverted
BIT 0 TX_BIT_POLARITY -- TX bit polarity control (TX default inversed
in MT7531)
1'b0: normal
1'b1: inverted
Till this patch the register write was only called when mediatek,pnswap
property was set which cannot be done for switch because the fw-node param
was always NULL from switch driver in the mtk_pcs_lynxi_create call.
Do not configure switch side like it's done before.

When mana_per_port_queue_reset_work_handler() runs after a previous
detach succeeded but attach failed, the port is left in a detached
state with apc->tx_qp and apc->rxqs already freed. Calling
mana_detach() again unconditionally leads to NULL pointer dereferences
during queue teardown.
Add an early exit in mana_detach() when the port is already in
detached state (!netif_device_present) for non-close callers, making
it safe to call idempotently. This allows the queue reset handler and
other recovery paths to simply retry mana_attach() without redundant
teardown.

When queue allocation fails partway through, the error cleanup frees
and NULLs apc->tx_qp and apc->rxqs. Multiple teardown paths such as
mana_remove(), mana_change_mtu() recovery, and internal error handling
in mana_alloc_queues() can subsequently call into functions that
dereference these pointers without NULL checks:
- mana_chn_setxdp() dereferences apc->rxqs[0], causing a NULL pointer
dereference panic (CR2: 0000000000000000 at mana_chn_setxdp+0x26).
- mana_destroy_vport() iterates apc->rxqs without a NULL check.
- mana_fence_rqs() iterates apc->rxqs without a NULL check.
- mana_dealloc_queues() iterates apc->tx_qp without a NULL check.
Add NULL guards for apc->rxqs in mana_fence_rqs(),
mana_destroy_vport(), and before the mana_chn_setxdp() call. Add a
NULL guard for apc->tx_qp in mana_dealloc_queues() to skip TX queue
draining when TX queues were never allocated or already freed.

Higher-Ranked Lifetime Types for Rust device drivers
Replace drvdata() with registration data on the auxiliary bus. Private
data is now scoped to the registration object, removing the ordering
constraints and lifetime complications that came with drvdata().
Add Higher-Ranked Lifetime Types (HRT) so driver structs can borrow
device resources like pci::Bar and IoMem directly, tied to the device
binding scope. This removes the need for Devres indirection and
ARef<Device> in most driver code.
This is a stable tag for other trees to merge.

When the I2C controller attempts a new transaction while the target
controller is shutting down or restarting, it can lead to bus lockups
and system bootloops if the hardware enters an inconsistent state.
Address this by ensuring that the internal state machines are properly
cleared when disabling the controller if target activity is detected.
If the controller remains active after disabling, perform a bus recovery
to reset it to a known good state.

drivers"
Danilo Krummrich <dakr@kernel.org> says:
Currently, Rust device drivers access device resources such as PCI BAR mappings
and I/O memory regions through Devres<T>.
Devres::access() provides zero-overhead access by taking a &Device<Bound>
reference as proof that the device is still bound. Since a &Device<Bound> is
available in almost all contexts by design, Devres is mostly a type-system level
proof that the resource is valid, but it can also be used from scopes without
this guarantee through its try_access() accessor.
This works well in general, but has a few limitations:
- Every access to a device resource goes through Devres::access(), which
despite zero cost, adds boilerplate to every access site.
- Destructors do not receive a &Device<Bound>, so they must use try_access(),
which can fail. In practice the access succeeds if teardown ordering is
correct, but the type system can't express this, forcing drivers to handle a
failure path that should never be taken.
- Sharing a resource across components (e.g. passing a BAR to a sub-component)
requires Arc<Devres<T>>.
- Device references must be stored as ARef<Device> rather than plain &Device
borrows.
These limitations stem from the driver's bus device private data being 'static
-- the driver struct cannot borrow from the device reference it receives in
probe(), even though it structurally cannot outlive the device binding.
This series introduces Higher-Ranked Lifetime Types (HRT) for Rust device
drivers. An HRT is a type that is generic over a lifetime -- it does not have a
fixed lifetime, but can be instantiated with any lifetime chosen by the caller.
Bus driver traits use a Generic Associated Type (GAT) type Data<'bound> to
introduce the lifetime on the private data, rather than parameterizing the
Driver trait itself. This avoids a driver trait global lifetime and avoids the
need for ForLt for bus device private data, making the bus implementations much
simpler. ForLt is only needed for auxiliary registration data, where the
lifetime is not introduced by a trait callback but must be threaded through
Registration.
With HRT, driver structs carry a lifetime parameter tied to the device binding
scope -- the interval of a bus device being bound to a driver. Device resources
like pci::Bar<'bound> and IoMem<'bound> are handed out with this lifetime, so
the compiler enforces at build time that they do not escape the binding scope.
Before:
struct MyDriver {
pdev: ARef<pci::Device>,
bar: Devres<pci::Bar<BAR_SIZE>>,
}
let io = self.bar.access(dev)?;
io.read32(OFFSET);
After:
struct MyDriver<'bound> {
pdev: &'bound pci::Device,
bar: pci::Bar<'bound, BAR_SIZE>,
}
self.bar.read32(OFFSET);
Lifetime-parameterized device resources can be put into a Devres at any point
via Bar::into_devres() / IoMem::into_devres(), providing the exact same
semantics as before. This is useful for resources shared across subsystem
boundaries where revocation is needed.
This also synergizes with the upcoming self-referential initialization support
in pin-init, which allows one field of the driver struct to borrow another
during initialization without unsafe code.
The same pattern is applied to auxiliary device registration data as a first
example beyond bus device private data. Registration<F: ForLt> can hold
lifetime-parameterized data tied to the parent driver's binding scope. Since the
auxiliary bus guarantees that the parent remains bound while the auxiliary
device is registered, the registration data can safely borrow the parent's
device resources.
More generally, binding resource lifetimes to a registration scope applies to
every registration that is scoped to a driver binding -- auxiliary devices,
class devices, IRQ handlers, workqueues.
A follow-up series extends this to class device registrations, starting with
DRM, so that class device callbacks (IOCTLs, etc.) can safely access device
resources through the separate registration data bound to the registration's
lifetime without Devres indirection.
Thanks to Gary for coming up with the ForLt implementation; thanks to Alice for
the early discussions around lifetime-parameterized private data that helped
shape the direction of this work.

Add FEAT_RENDER bool constant to the Driver trait to control
render node support. When enabled, the driver exposes /dev/dri/renderDXX
render nodes to userspace. The flag defaults to false, drivers can opt
in by setting it to true in their Driver implementation.
This is then enabled in the Tyr driver, while it's left disabled for
Nova for the time being.

kconfiglint reports:
K002: config TEGRA_BPMP selects visible symbol TEGRA_IVC which has
dependencies
TEGRA_IVC was originally introduced in
commit ca791d7f4256 ("firmware: tegra:
Add IVC library") as a user-visible
bool with a prompt ("Tegra IVC protocol"). At that time, TEGRA_BPMP
depended on TEGRA_IVC, requiring users to manually enable it.
Recently,
commit 78eb18020a88 ("firmware: tegra: Fix IVC dependency problems")
recognized that TEGRA_IVC is library code that should be activated via
`select` rather than user selection. That commit changed TEGRA_BPMP from
`depends on TEGRA_IVC` to `select TEGRA_IVC`, and restricted TEGRA_IVC's
prompt to only appear under COMPILE_TEST
(`bool "Tegra IVC protocol" if COMPILE_TEST`). The commit message
explicitly states: "The IVC code is library code that other drivers need to
select if they need that library."
However, the `if COMPILE_TEST` qualifier still leaves TEGRA_IVC as a
technically visible symbol, triggering K002 when TEGRA_BPMP selects it.
Since TEGRA_IVC depends on ARCH_TEGRA, it cannot be independently enabled
under COMPILE_TEST without ARCH_TEGRA anyway, limiting the value of the
standalone COMPILE_TEST path. TEGRA_BPMP itself provides adequate
COMPILE_TEST coverage for the IVC library through its own dependency chain.
Complete the transition to a pure library symbol by removing the prompt
entirely, making TEGRA_IVC a hidden bool activated only via select from
TEGRA_BPMP. This is consistent with the intent expressed in 78eb18020a88.
