Reserved commands will be used by SCSI LLDs for submitting internal
commands. Since the SCSI host, target and device limits do not apply to
the reserved command use cases, bypass the SCSI host limit checks for
reserved commands. Introduce the .queue_reserved_command() callback for
reserved commands. Additionally, do not activate the SCSI error handler
if a reserved command fails such that reserved commands can be submitted
from inside the SCSI error handler.
[ bvanassche: modified patch title and patch description. Renamed
.reserved_queuecommand() into .queue_reserved_command(). Changed
the second argument of __blk_mq_end_request() from 0 into error
code in the completion path if cmd->result != 0. Rewrote the
scsi_queue_rq() changes. See also

Allocate a pseudo SCSI device if 'nr_reserved_cmds' has been set. Pseudo
SCSI devices have the SCSI ID <max_id>:U64_MAX so they won't clash with
any devices the LLD might create. Pseudo SCSI devices are excluded from
scanning and will not show up in sysfs. Additionally, pseudo SCSI
devices are skipped by shost_for_each_device(). This prevents that the
SCSI error handler tries to submit a reset to a non-existent logical
unit.
Do not allocate a budget map for pseudo SCSI devices since the
cmd_per_lun limit does not apply to pseudo SCSI devices.
Do not perform queue depth ramp up / ramp down for pseudo SCSI devices.
Pseudo SCSI devices will be used to send internal commands to a storage
device.

Quite some drivers are using management commands internally. These
commands typically use the same tag pool as regular SCSI commands. Tags
for these management commands are set aside before allocating the
block-mq tag bitmap for regular SCSI commands. The block layer already
supports this via the reserved tag mechanism. Add a new field
'nr_reserved_cmds' to the SCSI host template to instruct the block layer
to set aside a tag space for these management commands by using reserved
tags. Exclude reserved commands from .can_queue because .can_queue is
visible in sysfs.
[ bvanassche: modified patch title and patch description. Left out the
following statements: "if (sht->nr_reserved_cmds)" and also
"if (sdev->host->nr_reserved_cmds) flags |= BLK_MQ_REQ_RESERVED;". Moved
nr_reserved_cmds declarations and statements close to the
corresponding can_queue declarations and statements. See also

This series adds support for power resources defined in acpi on ata
ports/devices. A device can define a power resource in an ata port/device,
which then gets powered on right before the port is probed. This can be
useful for devices, which have sata power connectors that are:
a: powered down by default
b: can be individually powered on
like in some synology nas devices. If thats the case it will be assumed,
that the power resource won't survive reboots and therefore the disk will
be stopped.

power state after a restart.

FC-LS and FC-GS specifications outline fields for registering a platform
name identifier (PNI) to the fabric. The PNI assists fabrics with
identifying the physical server source of frames in the fabric.
lpfc generates a PNI based partially on the uuid specific for the
system. Initial attempts to extract a uuid are made from SMBIOS's
System Information 08h uuid entry. If SMBIOS DMI does not exist, a PNI
is not generated and PNI registration with the fabric is skipped.
The PNI is submitted in FLOGI and FDISC frames. After successful fabric
login, the RSPNI_PNI CT frame is submitted to the fabric to register the
OS host name tying it to the PNI.

Currently, there is a kref put in the lpfc_cleanup() routine that takes
care of outstanding references on fabric controller ndlps in UNUSED
state. While typically there is a state change from UNUSED -> REGLOGIN
when the ndlp successfully logs into the fabric, there may be cases when
FLOGI is unsuccessful and the ndlp will remain in UNUSED state without a
registered rpi, yet the ndlp incorrectly has a kref count of one.
To address this, handling of Fabric Controller ndlps are moved into the
routines: lpfc_issue_els_scr(), lpfc_issue_els_rdf(),
lpfc_cmpl_els_disc_cmd().
In both lpfc_issue_els_scr() and lpfc_issue_els_rdf(), if there does not
exist a previously created fabric controller ndlp, an ndlp will be
created. Otherwise, we can reuse the pre-existing ndlp object.
In lpfc_cmpl_els_disc_cmd(), if the SCR or RDF are not successfully
issued, the initial reference on the ndlp that is not registered with
upper layers will be decremented with a kref_put().

In point-to-point topology, the driver sometimes defers the unsolicited
FLOGI LS_ACC until it sends its FLOGI to the remote port. When this
happens, lpfc neglects to release the ndlp allocated for the unsolicited
FLOGI. This patch adds code to release the ndlp for the deferred
unsolicited FLOGI LS_ACC.
An NLP_FLOGI_DFR_ACC flag is introduced to facilitate identifying an
ndlp with an expected deferred FLOGI LS_ACC completion. When
lpfc_cmpl_els_rsp() detects the correct qualifiers, it releases the
initial reference on the ndlp object. And when lpfc_cmpl_els_rsp()
exits, the remaining put for the deferred action is executed and the
ndlp is released.

Unregistration of an rpi object should be done when a PLOGI is received
as PLOGI receipt implies an implicit LOGO. Previously, the driver would
continue using the same, already registered, rpi and ACC the received
PLOGI.
Replace the ACC and early return statement with break to execute the
rest of the lpfc_rcv_plogi logic outside the switch case statement.
This ensures unregistration and reregistration of an rpi after PLOGI_ACC
completion.

Don Brace <don.brace@microchip.com> says:
These patches are based on Martin Petersen's 6.19/scsi-queue tree
https://git.kernel.org/pub/scm/linux/kernel/git/mkp/scsi.git
6.19/scsi-queue
This patch series includes four patches, with two main functional changes:
1. smartpqi-Add-timeout-value-to-RAID-path-requests-to-physical-devices
Sets a timeout value for requests sent to physical devices via the
RAID path. This prevents the controller firmware from waiting
indefinitely and allows it to time out requests a few seconds before
the OS issues Target Management Function (TMF) commands.
The timeout value sent to the firmware is set to 3 seconds less than
the OS timeout, which significantly reduces TMF invocations.
2. smartpqi-fix-Device-resources-accessed-after-device-removal
Fixes a race condition during device removal by:
* Checking for device removal in the reset handler and canceling any
pending reset work if the device is no longer present.
* Canceling outstanding TMF work items in the .sdev_destroy handler.
Together, these changes eliminate races between reset operations
and device removal.
The other two patches:
3. smartpqi-add-new-Hurray-Data-pci-device
Adds support for new Hurray Data PCI device.
No functional changes.
4. smartpqi-update-driver-version-to-2.1.36-026

Correct possible race conditions during device removal.
Previously, a scheduled work item to reset a LUN could still execute
after the device was removed, leading to use-after-free and other
resource access issues.
This race condition occurs because the abort handler may schedule a LUN
reset concurrently with device removal via sdev_destroy(), leading to
use-after-free and improper access to freed resources.
- Check in the device reset handler if the device is still present in
the controller's SCSI device list before running; if not, the reset
is skipped.
- Cancel any pending TMF work that has not started in sdev_destroy().
- Ensure device freeing in sdev_destroy() is done while holding the
LUN reset mutex to avoid races with ongoing resets.

Add a timeout value to requests sent to physical devices via the RAID
path.
A timeout value of zero means wait indefinitely, which may cause the OS
to issue Target Management Function (TMF) commands if the device does
not respond.
For input timeouts of 8 seconds or greater, the value sent to firmware
is reduced by 3 seconds to provide an earlier firmware timeout and allow
the OS additional time before timing out.
This change improves timeout handling between the driver, firmware, and
OS, helping to better manage device responsiveness and avoid indefinite
waits.

Currently if a user enqueues a work item using schedule_delayed_work()
the used wq is "system_wq" (per-cpu wq) while queue_delayed_work() uses
WORK_CPU_UNBOUND (used when a CPU is not specified). The same applies to
schedule_work() that is using system_wq and queue_work(), that makes use
again of WORK_CPU_UNBOUND. This lack of consistentcy cannot be
addressed without refactoring the API.
alloc_workqueue() treats all queues as per-CPU by default, while unbound
workqueues must opt-in via WQ_UNBOUND.
This default is suboptimal: most workloads benefit from unbound queues,
allowing the scheduler to place worker threads where they’re needed and
reducing noise when CPUs are isolated.
Continue the effort to refactor workqueue APIs, which has begun with the
change introducing new workqueues and a new alloc_workqueue flag:
commit 128ea9f6ccfb ("workqueue: Add system_percpu_wq and system_dfl_wq")
commit 930c2ea566af ("workqueue: Add new WQ_PERCPU flag")
Adds a new WQ_PERCPU flag to explicitly request alloc_workqueue() to be
per-CPU when WQ_UNBOUND has not been specified.
With the introduction of the WQ_PERCPU flag (equivalent to !WQ_UNBOUND),
any alloc_workqueue() caller that doesn’t explicitly specify WQ_UNBOUND
must now use WQ_PERCPU.
Once migration is complete, WQ_UNBOUND can be removed and unbound will
become the implicit default.

With commit 9604eea5bd3a ("scsi: st: Add third party poweron reset
handling") some customer tape applications fail from being unable to
complete ioctls to verify ID information for the device when there has
been any type of reset event to their tape devices.
The st driver currently will fail all standard SCSI ioctls if a call to
flush_buffer() fails in st_ioctl(). This causes ioctls which otherwise
have no effect on tape state to succeed or fail based on events
unrelated to the requested ioctl.
This makes SCSI information ioctls unreliable after a reset even if no
buffering is in use. With a reset setting the pos_unknown field,
flush_buffer() will report failure and fail all ioctls. So any
application expecting to use ioctls to check the identify the device
will be unable to do so in such a state.
For SCSI information ioctls, avoid the need for a buffer flush and allow
the ioctls to execute regardless of buffer state.

Commit b76b840fd933 ("dm: Fix dm-zoned-reclaim zone write pointer
alignment") introduced an indirect call for the callback function of a
report zones executed with blkdev_report_zones(). This is necessary so
that the function disk_zone_wplug_sync_wp_offset() can be called to
refresh a zone write plug zone write pointer offset after a write error.
However, this solution makes following the path of a zone information
harder to understand.
Clean this up by introducing the new blk_report_zones_args structure to
define a zone report callback and its private data and introduce the
helper function disk_report_zone() which calls both
disk_zone_wplug_sync_wp_offset() and the zone report user callback
function for all zones of a zone report. This helper function must be
called by all block device drivers that implement the report zones
block operation in order to correctly report a zone information.
All block device drivers supporting the report_zones block operation are
updated to use this new scheme.

The driver calls asc_prt_scsi_host() -> scsi_host_busy() prior to
calling scsi_add_host(). This should not be done, and has raised issues
for other drivers, like [0].
Function asc_prt_scsi_host() only has a single callsite, as above, where
the shost busy count would always be 0.
Avoid printing the shost busy count to avoid this problem.

I guess that the @shost comment on scsi_host_busy() was copied from
scsi_host_get() (as it is the same), however they do not do the same
thing.
Also drop reference to busy counter, which has been removed.

-Wflex-array-member-not-at-end was introduced in GCC-14, and we are
getting ready to enable it, globally.
Use the new TRAILING_OVERLAP() helper to fix the following warnings:
drivers/scsi/megaraid/megaraid_sas_fusion.h:1153:31: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end]
drivers/scsi/megaraid/megaraid_sas_fusion.h:1198:32: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end]
This helper creates a union between a flexible-array member (FAM) and a
set of MEMBERS that would otherwise follow it --in this case 'struct
MR_LD_SPAN_MAP ldSpanMap[MAX_LOGICAL_DRIVES_DYN]' and 'struct
MR_LD_SPAN_MAP ldSpanMap[MAX_LOGICAL_DRIVES]' in the corresponding
structures.
This overlays the trailing members onto the FAM (struct MR_LD_SPAN_MAP
ldSpanMap[];) while keeping the FAM and the start of MEMBERS aligned.
The static_assert() ensures this alignment remains, and it's
intentionally placed inmediately after the corresponding structures --no
blank line in between.

-Wflex-array-member-not-at-end was introduced in GCC-14, and we are
getting ready to enable it, globally.
Move the conflicting declaration (which happens to be in a union, so
we're moving the entire union) to the end of the corresponding
structure. Notice that `struct ssp_response_iu` is a flexible structure,
this is a structure that contains a flexible-array member.

Fix this regression by making scsi_host_busy() check whether the SCSI
host tag set has already been initialized. tag_set->ops is set by
scsi_mq_setup_tags() just before blk_mq_alloc_tag_set() is called. This
fix is based on the assumption that scsi_host_busy() and
scsi_mq_setup_tags() calls are serialized. This is the case in the UFS
driver.

The "offset" comes from the skb->data that we received. Here the code
is verifying that "offset + len" is within bounds however it does not
take integer overflows into account. Use size_add() to be safe.
This would only be an issue on 32bit systems which are probably a very
small percent of the users. Still, it's worth fixing just for
correctness sake.

issuing CPU
When selecting an outgoing channel for I/O, storvsc tries to select a
channel with a returning CPU that is not the same as issuing CPU. This
worked well in the past, however it doesn't work well when the Hyper-V
exposes a large number of channels (up to the number of all CPUs). Use a
different CPU for returning channel is not efficient on Hyper-V.
Change this behavior by preferring to the channel with the same CPU as
the current I/O issuing CPU whenever possible.
Tests have shown improvements in newer Hyper-V/Azure environment, and no
regression with older Hyper-V/Azure environments.

Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Add PCI_FIND_NEXT_CAP() and PCI_FIND_NEXT_EXT_CAP() macros that
take config space accessor functions.
Implement pci_find_capability(), pci_find_ext_capability(), and
dwc, dwc endpoint, and cadence capability search interfaces with
them (Hans Zhang)
- Leave parent unit address 0 in 'interrupt-map' so that when we
build devicetree nodes to describe PCI functions that contain
multiple peripherals, we can build this property even when
interrupt controllers lack 'reg' properties (Lorenzo Pieralisi)
- Add a Xeon 6 quirk to disable Extended Tags and limit Max Read
Request Size to 128B to avoid a performance issue (Ilpo Järvinen)
- Add sysfs 'serial_number' file to expose the Device Serial Number
(Matthew Wood)
- Fix pci_acpi_preserve_config() memory leak (Nirmoy Das)
Resource management:
- Align m68k pcibios_enable_device() with other arches (Ilpo
Järvinen)
- Remove sparc pcibios_enable_device() implementations that don't do
anything beyond what pci_enable_resources() does (Ilpo Järvinen)
- Remove mips pcibios_enable_resources() and use
pci_enable_resources() instead (Ilpo Järvinen)
- Clean up bridge window sizing and assignment (Ilpo Järvinen),
including:
- Leave non-claimed bridge windows disabled
- Enable bridges even if a window wasn't assigned because not all
windows are required by downstream devices
- Preserve bridge window type when releasing the resource, since
the type is needed for reassignment
- Consolidate selection of bridge windows into two new
interfaces, pbus_select_window() and
pbus_select_window_for_type(), so this is done consistently
- Compute bridge window start and end earlier to avoid logging
stale information
MSI:
- Add quirk to disable MSI on RDC PCI to PCIe bridges (Marcos Del Sol
Vives)
Error handling:
- Align AER with EEH by allowing drivers to request a Bus Reset on
Non-Fatal Errors (in addition to the reset on Fatal Errors that we
already do) (Lukas Wunner)
- If error recovery fails, emit FAILED_RECOVERY uevents for the
devices, not for the bridge leading to them.
This makes them correspond to BEGIN_RECOVERY uevents (Lukas Wunner)
- Align AER with EEH by calling err_handler.error_detected()
callbacks to notify drivers if error recovery fails (Lukas Wunner)
- Align AER with EEH by restoring device error_state to
pci_channel_io_normal before the err_handler.slot_reset() callback.
This is earlier than before the err_handler.resume() callback
(Lukas Wunner)
- Emit a BEGIN_RECOVERY uevent when driver's
err_handler.error_detected() requests a reset, as well as when it
says recovery is complete or can be done without a reset (Niklas
Schnelle)
- Align s390 with AER and EEH by emitting uevents during error
recovery (Niklas Schnelle)
- Align EEH with AER and s390 by emitting BEGIN_RECOVERY,
SUCCESSFUL_RECOVERY, or FAILED_RECOVERY uevents depending on the
result of err_handler.error_detected() (Niklas Schnelle)
- Fix a NULL pointer dereference in aer_ratelimit() when ACPI GHES
error information identifies a device without an AER Capability
(Breno Leitao)
- Update error decoding and TLP Log printing for new errors in
current PCIe base spec (Lukas Wunner)
- Update error recovery documentation to match the current code
and use consistent nomenclature (Lukas Wunner)
ASPM:
- Enable all ClockPM and ASPM states for devicetree platforms, since
there's typically no firmware that enables ASPM
This is a risky change that may uncover hardware or configuration
defects at boot-time rather than when users enable ASPM via sysfs
later. Booting with "pcie_aspm=off" prevents this enabling
(Manivannan Sadhasivam)
- Remove the qcom code that enabled ASPM (Manivannan Sadhasivam)
Power management:
- If a device has already been disconnected, e.g., by a hotplug
removal, don't bother trying to resume it to D0 when detaching the
driver.
This avoids annoying "Unable to change power state from D3cold to
D0" messages (Mario Limonciello)
- Ensure devices are powered up before config reads for
'max_link_width', 'current_link_speed', 'current_link_width',
'secondary_bus_number', and 'subordinate_bus_number' sysfs files.
This prevents using invalid data (~0) in drivers or lspci and,
depending on how the PCIe controller reports errors, may avoid
error interrupts or crashes (Brian Norris)
Virtualization:
- Add rescan/remove locking when enabling/disabling SR-IOV, which
avoids list corruption on s390, where disabling SR-IOV also
generates hotplug events (Niklas Schnelle)
Peer-to-peer DMA:
- Free struct p2p_pgmap, not a member within it, in the
pci_p2pdma_add_resource() error path (Sungho Kim)
Endpoint framework:
- Document sysfs interface for BAR assignment of vNTB endpoint
functions (Jerome Brunet)
- Fix array underflow in endpoint BAR test case (Dan Carpenter)
- Skip endpoint IRQ test if the IRQ is out of range to avoid false
errors (Christian Bruel)
- Fix endpoint test case for controllers with fixed-size BARs smaller
than requested by the test (Marek Vasut)
- Restore inbound translation when disabling doorbell so the endpoint
doorbell test case can be run more than once (Niklas Cassel)
- Avoid a NULL pointer dereference when releasing DMA channels in
endpoint DMA test case (Shin'ichiro Kawasaki)
- Convert tegra194 interrupt number to MSI vector to fix endpoint
Kselftest MSI_TEST test case (Niklas Cassel)
- Reset tegra194 BARs when running in endpoint mode so the BAR tests
don't overwrite the ATU settings in BAR4 (Niklas Cassel)
- Handle errors in tegra194 BPMP transactions so we don't mistakenly
skip future PERST# assertion (Vidya Sagar)
AMD MDB PCIe controller driver:
- Update DT binding example to separate PERST# to a Root Port stanza
to make multiple Root Ports possible in the future (Sai Krishna
Musham)
- Add driver support for PERST# being described in a Root Port
stanza, falling back to the host bridge if not found there (Sai
Krishna Musham)
Freescale i.MX6 PCIe controller driver:
- Enable the 3.3V Vaux supply if available so devices can request
wakeup with either Beacon or WAKE# (Richard Zhu)
MediaTek PCIe Gen3 controller driver:
- Add optional sys clock ready time setting to avoid sys_clk_rdy
signal glitching in MT6991 and MT8196 (AngeloGioacchino Del Regno)
- Add DT binding and driver support for MT6991 and MT8196
(AngeloGioacchino Del Regno)
NVIDIA Tegra PCIe controller driver:
- When asserting PERST#, disable the controller instead of mistakenly
disabling the PLL twice (Nagarjuna Kristam)
- Convert struct tegra_msi mask_lock to raw spinlock to avoid a lock
nesting error (Marek Vasut)
Qualcomm PCIe controller driver:
- Select PCI Power Control Slot driver so slot voltage rails can be
turned on/off if described in Root Port devicetree node (Qiang Yu)
- Parse only PCI bridge child nodes in devicetree, skipping unrelated
nodes such as OPP (Operating Performance Points), which caused
probe failures (Krishna Chaitanya Chundru)
- Add 8.0 GT/s and 32.0 GT/s equalization settings (Ziyue Zhang)
- Consolidate Root Port 'phy' and 'reset' properties in struct
qcom_pcie_port, regardless of whether we got them from the Root
Port node or the host bridge node (Manivannan Sadhasivam)
- Fetch and map the ELBI register space in the DWC core rather than
in each driver individually (Krishna Chaitanya Chundru)
- Enable ECAM mechanism in DWC core by setting up iATU with 'CFG
Shift Feature' and use this in the qcom driver (Krishna Chaitanya
Chundru)
- Add SM8750 compatible to qcom,pcie-sm8550.yaml (Krishna Chaitanya
Chundru)
- Update qcom,pcie-x1e80100.yaml to allow fifth PCIe host on Qualcomm
Glymur, which is compatible with X1E80100 but doesn't have the
cnoc_sf_axi clock (Qiang Yu)
Renesas R-Car PCIe controller driver:
- Fix a typo that prevented correct PHY initialization (Marek Vasut)
- Add a missing 1ms delay after PWR reset assertion as required by
the V4H manual (Marek Vasut)
- Assure reset has completed before DBI access to avoid SError (Marek
Vasut)
- Fix inverted PHY initialization check, which sometimes led to
timeouts and failure to start the controller (Marek Vasut)
- Pass the correct IRQ domain to generic_handle_domain_irq() to fix a
regression when converting to msi_create_parent_irq_domain()
(Claudiu Beznea)
- Drop the spinlock protecting the PMSR register - it's no longer
required since pci_lock already serializes accesses (Marek Vasut)
- Convert struct rcar_msi mask_lock to raw spinlock to avoid a lock
nesting error (Marek Vasut)
SOPHGO PCIe controller driver:
- Check for existence of struct cdns_pcie.ops before using it to
allow Cadence drivers that don't need to supply ops (Chen Wang)
- Add DT binding and driver for the SOPHGO SG2042 PCIe controller
(Chen Wang)
STMicroelectronics STM32MP25 PCIe controller driver:
- Update pinctrl documentation of initial states and use in runtime
suspend/resume (Christian Bruel)
- Add pinctrl_pm_select_init_state() for use by stm32 driver, which
needs it during resume (Christian Bruel)
- Add devicetree bindings and drivers for the STMicroelectronics
STM32MP25 in host and endpoint modes (Christian Bruel)
Synopsys DesignWare PCIe controller driver:
- Add support for x16 in devicetree 'num-lanes' property (Konrad
Dybcio)
- Verify that if DT specifies a single IRQ for all eDMA channels, it
is named 'dma' (Niklas Cassel)
TI J721E PCIe driver:
- Add MODULE_DEVICE_TABLE() so driver can be autoloaded (Siddharth
Vadapalli)
- Power controller off before configuring the glue layer so the
controller latches the correct values on power-on (Siddharth
Vadapalli)
TI Keystone PCIe controller driver:
- Use devm_request_irq() so 'ks-pcie-error-irq' is freed when driver
exits with error (Siddharth Vadapalli)
- Add Peripheral Virtualization Unit (PVU), which restricts DMA from
PCIe devices to specific regions of host memory, to the ti,am65
binding (Jan Kiszka)
Xilinx NWL PCIe controller driver:
- Clear bootloader E_ECAM_CONTROL before merging in the new driver
value to avoid writing invalid values (Jani Nurminen)"
