ata: libata-scsi: Improve CDL control
With ATA devices supporting the CDL feature, using CDL requires that the
feature be enabled with a SET FEATURES command. This command is issued
as the translated command for the MODE SELECT command issued by
scsi_cdl_enable() when the user enables CDL through the device
cdl_enable sysfs attribute.
Currently, ata_mselect_control_ata_feature() always translates a MODE
SELECT command for the ATA features subpage of the control mode page to
a SET FEATURES command to enable or disable CDL based on the cdl_ctrl
field. However, there is no need to issue the SET FEATURES command if:
1) The MODE SELECT command requests disabling CDL and CDL is already
disabled.
2) The MODE SELECT command requests enabling CDL and CDL is already
enabled.
Fix ata_mselect_control_ata_feature() to issue the SET FEATURES command
only when necessary. Since enabling CDL also implies a reset of the CDL
statistics log page, avoiding useless CDL enable operations also avoids
clearing the CDL statistics log.
Also add debug messages to clearly signal when CDL is being enabled or
disabled using a SET FEATURES command.

ata: libata-scsi: Fix ata_msense_control_ata_feature()
For the ATA features subpage of the control mode page, the T10 SAT-6
specifications state that:
For a MODE SENSE command, the SATL shall return the CDL_CTRL field value
that was last set by an application client.
However, the function ata_msense_control_ata_feature() always sets the
CDL_CTRL field to the 0x02 value to indicate support for the CDL T2A and
T2B pages. This is thus incorrect and the value 0x02 must be reported
only after the user enables the CDL feature, which is indicated with the
ATA_DFLAG_CDL_ENABLED device flag. When this flag is not set, the
CDL_CTRL field of the ATA feature subpage of the control mode page must
report a value of 0x00.
Fix ata_msense_control_ata_feature() to report the correct values for
the CDL_CTRL field, according to the enable/disable state of the device
CDL feature.

ata: libata-scsi: Fix ata_mselect_control_ata_feature() return type
The function ata_mselect_control_ata_feature() has a return type defined
as unsigned int but this function may return negative error codes, which
are correctly propagated up the call chain as integers.
Fix ata_mselect_control_ata_feature() to have the correct int return
type.
While at it, also fix a typo in this function description comment.

ata: libata-sata: Save all fields from sense data descriptor
When filling the taskfile result for a successful NCQ command, we use
the SDB FIS from the FIS Receive Area, see e.g. ahci_qc_ncq_fill_rtf().
However, the SDB FIS only has fields STATUS and ERROR.
For a successful NCQ command that has sense data, we will have a
successful sense data descriptor, in the Sense Data for Successful NCQ
Commands log.
Since we have access to additional taskfile result fields, fill in these
additional fields in qc->result_tf.
This matches how for failing/aborted NCQ commands, we will use e.g.
ahci_qc_fill_rtf() to fill in some fields, but then for the command that
actually caused the NCQ error, we will use ata_eh_read_log_10h(), which
provides additional fields, saving additional fields/overriding the
qc->result_tf that was fetched using ahci_qc_fill_rtf().

ata: sata_sx4: Add error handling in pdc20621_i2c_read()
The function pdc20621_prog_dimm0() calls the function pdc20621_i2c_read() but does not handle the error if the read fails. This could lead to process with invalid data. A proper implementation can be found in /source/drivers/ata/sata_sx4.c, pdc20621_prog_dimm_global(). As mentioned in its commit: |

A treewide hrtimer timer cleanup
hrtimers are initialized with hrtimer_init() and a subsequent store to the callback pointer. This turned out to be suboptimal for the upcoming Rust integration and is obviously a silly implementation to begin with. This cleanup replaces the hrtimer_init(T); T->function = cb; sequence with hrtimer_setup(T, cb); The conversion was done with Coccinelle and a few manual fixups. Once the conversion has completely landed in mainline, hrtimer_init() will be removed and the hrtimer::function becomes a private member. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAmff5jQTHHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYoVvRD/wKtuwmiA66NJFgXC0qVq82A6fO3bY8 GBdbfysDJIbqGu5PTcULTbJ8qkqv3jeLUv6CcXvS4sZ7y/uJQl2lzf8yrD/0bbwc rLI6sHiPSZmK93kNVN4X5H7kvt7cE/DYC9nnEOgK3BY5FgKc4n9887d4aVBhL8Lv ODwVXvZ+xi351YCj7qRyPU24zt/p4tkkT1o2k4a0HBluqLI0D+V20fke9IERUL8r d1uWKlcn0TqYDesE8HXKIhbst3gx52rMJrXBJDHwFmG6v8Pj1fkTXCVpPo8QcBz8 OTVkpomN9f/Tx4+GZwhZOF86LhLL3OhxD6pT7JhFCXdmSGv+Ez8uyk1YZysM/XpV Juy/1yAcBpDIDkmhMFGdAAn48Nn9Fotty0r4je60zSEp1d/4QMXcFme29qr2JTUE iWnQ/HD6DxUjVHqy7CYvvo26Xegg1C7qgyOVt4PYZwAM1VKF5P3kzYTb4SAdxtop Tpji1sfW9QV08jqMNo6XntD32DSP9S2HqjO9LwBw700jnx2jjJ35fcJs6iodMOUn gckIZLMn3L0OoglPdyA5O7SNTbKE7aFiRKdnT/cJtR3Fa39Qu27CwC5gfiyuie9I Q+LG8GLuYSBHXAR+PBK4GWlzJ7Dn8k3eqmbnLeKpRMsU6ZzcttgA64xhaviN2wN0 iJbvLJeisXr3GA== =bYAX -----END PGP SIGNATURE----- Merge tag 'timers-cleanups-2025-03-23' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull timer cleanups from Thomas Gleixner: "A treewide hrtimer timer cleanup hrtimers are initialized with hrtimer_init() and a subsequent store to the callback pointer.

ata: ahci: simplify init function
This patch moves all the IRQ vector allocations into a single function. Instead of having the allocations spread out over two separate call sites everything will be handled in ahci_init_irq. Also a direct call into pci(m)_intx will be removed. The main part of this change is done by adding a PCI_IRQ_INTX flag into an already existing pci_alloc_irq_vectors invocation. In the current implementation of the pci_alloc_irq_vectors is the sequence of calls msi-x -> msi -> legacy irq and whatever there succeeds stops the call chain. That makes it impossible to merge all instances into as a single call to pci_alloc_irq_vectors since the order of calls there is: multiple msi-x a single msi a single msi-x a legacy irq. The two last steps can be merged into a single one which are the msi-x and legacy irq option. When PCI_IRQ_INTX flag is set the pci_alloc_irq_vectors succeeds in almost all cases - that makes it possible to convert ahci_init_irq(msi) into a void function. The exception is when dev->irq is zero then the pci_alloc_irq_vectors may return with an error code also pci_intx isn't called from pci_alloc_irq_vectors and thus certain pci calls aren't performed. That's just a negligible issue as later in ahci_init_one the (zero) value of dev->irq is via pci_irq_vector assigned to hpriv->irq. That value is then later tested in ahci_host_activate->ata_host_activate where it is welcomed with a WARN_ON message and fails with setting up irq and then the probe function (ahci_init_one) fails. The special zero value's meaning is that polling mode is being be set up which isn't the case. No functional change.

ahci: Marvell 88SE9215 controllers prefer DMA for ATAPI
We use CD/DVD drives under Marvell 88SE9215 SATA controller on many Loongson-based machines. We found its PIO doesn't work well, and on the opposite its DMA seems work very well. We don't know the detail of the 88SE9215 SATA controller, but we have tested different CD/DVD drives and they all have problems under 88SE9215 (but they all work well under an Intel SATA controller). So, we consider this problem is bound to 88SE9215 SATA controller rather than bound to CD/DVD drives. As a solution, we define a new dedicated AHCI board id which is named board_ahci_yes_fbs_atapi_dma for 88SE9215, and for this id we set the AHCI_HFLAG_ATAPI_DMA_QUIRK and ATA_QUIRK_ATAPI_MOD16_DMA flags on the SATA controller in order to prefer ATAPI DMA.

ata: libata: Fix NCQ Non-Data log not supported print
Currently, both ata_dev_config_ncq_send_recv() - which checks for NCQ
Send/Recv Log (Log Address 13h) and ata_dev_config_ncq_non_data() -
which checks for NCQ Non-Data Log (Log Address 12h), uses the same
print when the log is not supported:
"NCQ Send/Recv Log not supported"
This seems like a copy paste error, since NCQ Non-Data Log is actually
a separate log.
Fix the print to reference the correct log.

ata: libata-eh: Do not use ATAPI DMA for a device limited to PIO mode
atapi_eh_request_sense() currently uses ATAPI DMA if the SATA controller has ATA_FLAG_PIO_DMA (PIO cmds via DMA) set. However, ATA_FLAG_PIO_DMA is a flag that can be set by a low-level driver on a port at initialization time, before any devices are scanned. If a controller detects a connected device that only supports PIO, we set the flag ATA_DFLAG_PIO. Modify atapi_eh_request_sense() to not use ATAPI DMA if the connected device only supports PIO.

ata: libata-sff: Ensure that we cannot write outside the allocated buffer
reveliofuzzing reported that a SCSI_IOCTL_SEND_COMMAND ioctl with out_len set to 0xd42, SCSI command set to ATA_16 PASS-THROUGH, ATA command set to ATA_NOP, and protocol set to ATA_PROT_PIO, can cause ata_pio_sector() to write outside the allocated buffer, overwriting random memory. While a ATA device is supposed to abort a ATA_NOP command, there does seem to be a bug either in libata-sff or QEMU, where either this status is not set, or the status is cleared before read by ata_sff_hsm_move(). Anyway, that is most likely a separate bug. Looking at __atapi_pio_bytes(), it already has a safety check to ensure that __atapi_pio_bytes() cannot write outside the allocated buffer. Add a similar check to ata_pio_sector(), such that also ata_pio_sector() cannot write outside the allocated buffer.

Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Batch sizing of multiple BARs while memory decoding is disabled
instead of disabling/enabling decoding for each BAR individually;
this optimizes virtualized environments where toggling decoding
enable is expensive (Alex Williamson)
- Add host bridge .enable_device() and .disable_device() hooks for
bridges that need to configure things like Requester ID to StreamID
mapping when enabling devices (Frank Li)
- Extend struct pci_ecam_ops with .enable_device() and
.disable_device() hooks so drivers that use pci_host_common_probe()
instead of their own .probe() have a way to set the
.enable_device() callbacks (Marc Zyngier)
- Drop 'No bus range found' message so we don't complain when DTs
don't specify the default 'bus-range = <0x00 0xff>' (Bjorn Helgaas)
- Rename the drivers/pci/of_property.c struct of_pci_range to
of_pci_range_entry to avoid confusion with the global of_pci_range
in include/linux/of_address.h (Bjorn Helgaas)
Driver binding:
- Update resource request API documentation to encourage callers to
supply a driver name when requesting resources (Philipp Stanner)
- Export pci_intx_unmanaged() and pcim_intx() (always managed) so
callers of pci_intx() (which is sometimes managed) can explicitly
choose the one they need (Philipp Stanner)
- Convert drivers from pci_intx() to always-managed pcim_intx() or
never-managed pci_intx_unmanaged(): amd_sfh, ata (ahci, ata_piix,
pata_rdc, sata_sil24, sata_sis, sata_uli, sata_vsc), bnx2x, bna,
ntb, qtnfmac, rtsx, tifm_7xx1, vfio, xen-pciback (Philipp Stanner)
- Remove pci_intx_unmanaged() since pci_intx() is now always
unmanaged and pcim_intx() is always managed (Philipp Stanner)
Error handling:
- Unexport pcie_read_tlp_log() to encourage drivers to use PCI core
logging rather than building their own (Ilpo Järvinen)
- Move TLP Log handling to its own file (Ilpo Järvinen)
- Store number of supported End-End TLP Prefixes always so we can
read the correct number of DWORDs from the TLP Prefix Log (Ilpo
Järvinen)
- Read TLP Prefixes in addition to the Header Log in
pcie_read_tlp_log() (Ilpo Järvinen)
- Add pcie_print_tlp_log() to consolidate printing of TLP Header and
Prefix Log (Ilpo Järvinen)
- Quirk the Intel Raptor Lake-P PIO log size to accommodate vendor
BIOSes that don't configure it correctly (Takashi Iwai)
ASPM:
- Save parent L1 PM Substates config so when we restore it along with
an endpoint's config, the parent info isn't junk (Jian-Hong Pan)
Power management:
- Avoid D3 for Root Ports on TUXEDO Sirius Gen1 with old BIOS because
the system can't wake up from suspend (Werner Sembach)
Endpoint framework:
- Destroy the EPC device in devm_pci_epc_destroy(), which previously
didn't call devres_release() (Zijun Hu)
- Finish virtual EP removal in pci_epf_remove_vepf(), which
previously caused a subsequent pci_epf_add_vepf() to fail with
-EBUSY (Zijun Hu)
- Write BAR_MASK before iATU registers in pci_epc_set_bar() so we
don't depend on the BAR_MASK reset value being larger than the
requested BAR size (Niklas Cassel)
- Prevent changing BAR size/flags in pci_epc_set_bar() to prevent
reads from bypassing the iATU if we reduced the BAR size (Niklas
Cassel)
- Verify address alignment when programming iATU so we don't attempt
to write bits that are read-only because of the BAR size, which
could lead to directing accesses to the wrong address (Niklas
Cassel)
- Implement artpec6 pci_epc_features so we can rely on all drivers
supporting it so we can use it in EPC core code (Niklas Cassel)
- Check for BARs of fixed size to prevent endpoint drivers from
trying to change their size (Niklas Cassel)
- Verify that requested BAR size is a power of two when endpoint
driver sets the BAR (Niklas Cassel)
Endpoint framework tests:
- Clear pci-epf-test dma_chan_rx, not dma_chan_tx, after freeing
dma_chan_rx (Mohamed Khalfella)
- Correct the DMA MEMCPY test so it doesn't fail if the Endpoint
supports both DMA_PRIVATE and DMA_MEMCPY (Manivannan Sadhasivam)
- Add pci-epf-test and pci_endpoint_test support for capabilities
(Niklas Cassel)
- Add Endpoint test for consecutive BARs (Niklas Cassel)
- Remove redundant comparison from Endpoint BAR test because a > 1MB
BAR can always be exactly covered by iterating with a 1MB buffer
(Hans Zhang)
- Move and convert PCI Endpoint tests from tools/pci to Kselftests
(Manivannan Sadhasivam)
Apple PCIe controller driver:
- Convert StreamID mapping configuration from a bus notifier to the
.enable_device() and .disable_device() callbacks (Marc Zyngier)
Freescale i.MX6 PCIe controller driver:
- Add Requester ID to StreamID mapping configuration when enabling
devices (Frank Li)
- Use DWC core suspend/resume functions for imx6 (Frank Li)
- Add suspend/resume support for i.MX8MQ, i.MX8Q, and i.MX95 (Richard
Zhu)
- Add DT compatible string 'fsl,imx8q-pcie-ep' and driver support for

Li)
- Add DT binding for optional i.MX95 Refclk and driver support to
enable it if the platform hasn't enabled it (Richard Zhu)
- Configure PHY based on controller being in Root Complex or Endpoint
mode (Frank Li)
- Rely on dbi2 and iATU base addresses from DT via
dw_pcie_get_resources() instead of hardcoding them (Richard Zhu)
- Deassert apps_reset in imx_pcie_deassert_core_reset() since it is
asserted in imx_pcie_assert_core_reset() (Richard Zhu)
- Add missing reference clock enable or disable logic for IMX6SX,
IMX7D, IMX8MM (Richard Zhu)
- Remove redundant imx7d_pcie_init_phy() since
imx7d_pcie_enable_ref_clk() does the same thing (Richard Zhu)
Freescale Layerscape PCIe controller driver:
- Simplify by using syscon_regmap_lookup_by_phandle_args() instead
of syscon_regmap_lookup_by_phandle() followed by
of_property_read_u32_array() (Krzysztof Kozlowski)
Marvell MVEBU PCIe controller driver:
- Add MODULE_DEVICE_TABLE() to enable module autoloading (Liao Chen)
MediaTek PCIe Gen3 controller driver:
- Use clk_bulk_prepare_enable() instead of separate
clk_bulk_prepare() and clk_bulk_enable() (Lorenzo Bianconi)
- Rearrange reset assert/deassert so they're both done in the
*_power_up() callbacks (Lorenzo Bianconi)
- Document that Airoha EN7581 requires PHY init and power-on before
PHY reset deassert, unlike other MediaTek Gen3 controllers (Lorenzo
Bianconi)
- Move Airoha EN7581 post-reset delay from the en7581 clock .enable()
method to mtk_pcie_en7581_power_up() (Lorenzo Bianconi)
- Sleep instead of delay during Airoha EN7581 power-up, since this is
a non-atomic context (Lorenzo Bianconi)
- Skip PERST# assertion on Airoha EN7581 during probe and
suspend/resume to avoid a hardware defect (Lorenzo Bianconi)
- Enable async probe to reduce system startup time (Douglas Anderson)
Microchip PolarFlare PCIe controller driver:
- Set up the inbound address translation based on whether the
platform allows coherent or non-coherent DMA (Daire McNamara)
- Update DT binding such that platforms are DMA-coherent by default
and must specify 'dma-noncoherent' if needed (Conor Dooley)
Mobiveil PCIe controller driver:
- Convert mobiveil-pcie.txt to YAML and update 'interrupt-names'
and 'reg-names' (Frank Li)
Qualcomm PCIe controller driver:
- Add DT SM8550 and SM8650 optional 'global' interrupt for link
events (Neil Armstrong)
- Add DT 'compatible' strings for IPQ5424 PCIe controller (Manikanta
Mylavarapu)

DWC core not to wait for link up (Krishna chaitanya chundru)
Renesas R-Car PCIe controller driver:
- Avoid passing stack buffer as resource name (King Dix)
Rockchip PCIe controller driver:
- Simplify clock and reset handling by using bulk interfaces (Anand

rockchip_pcie_disable_clocks() (Anand Moon)
- Return -ENOMEM, not success, when pci_epc_mem_alloc_addr() fails
(Dan Carpenter)
Rockchip DesignWare PCIe controller driver:
- Use dll_link_up IRQ to detect Link Up and enumerate devices so
users don't have to manually rescan (Niklas Cassel)
- Tell DWC core not to wait for link up since the 'sys' interrupt is
required and detects Link Up events (Niklas Cassel)
Synopsys DesignWare PCIe controller driver:
- Don't wait for link up in DWC core if driver can detect Link Up
event (Krishna chaitanya chundru)
- Update ICC and OPP votes after Link Up events (Krishna chaitanya
chundru)
- Always stop link in dw_pcie_suspend_noirq(), which is required at
least for i.MX8QM to re-establish link on resume (Richard Zhu)
- Drop racy and unnecessary LTSSM state check before sending
PME_TURN_OFF message in dw_pcie_suspend_noirq() (Richard Zhu)
- Add struct of_pci_range.parent_bus_addr for devices that need their
immediate parent bus address, not the CPU address, e.g., to program
an internal Address Translation Unit (iATU) (Frank Li)
TI DRA7xx PCIe controller driver:
- Simplify by using syscon_regmap_lookup_by_phandle_args() instead of
syscon_regmap_lookup_by_phandle() followed by
of_parse_phandle_with_fixed_args() or of_property_read_u32_index()

ata: Use always-managed version of pci_intx()
pci_intx() is a hybrid function which can sometimes be managed through devres. To remove this hybrid nature from pci_intx(), it is necessary to port users to either an always-managed or a never-managed version. All users in ata enable their PCI devices with pcim_enable_device(). Thus, they need the always-managed version. Replace pci_intx() with pcim_intx().

ahci: Introduce ahci_ignore_port() helper
libahci and AHCI drivers may ignore some ports if the port is invalid (its ID does not correspond to a valid physical port) or if the user explicitly requested the port to be ignored with the mask_port_map ahci module parameter. Such port that shall be ignored can be identified by checking that the bit corresponding to the port ID is not set in the mask_port_map field of struct ahci_host_priv. E.g. code such as: "if (!(hpriv->mask_port_map & (1 << portid)))". Replace all direct use of the mask_port_map field to detect such port with the new helper inline function ahci_ignore_port() to make the code more readable/easier to understand. The comment describing the mask_port_map field of struct ahci_host_priv is also updated to be more accurate.

ata: libahci_platform: support non-consecutive port numbers
So far ahci_platform relied on number of child nodes in firmware to allocate arrays and expected port numbers to start from 0 without holes. This number of ports is then set in private structure for use when configuring phys and regulators. Some platforms may not use every port of an ahci controller. E.g. SolidRUN CN9130 Clearfog uses only port 1 but not port 0, leading to the following errors during boot: [ 1.719476] ahci f2540000.sata: invalid port number 1 [ 1.724562] ahci f2540000.sata: No port enabled Update all accessesors of ahci_host_priv phys and target_pwrs arrays to support holes. Access is gated by hpriv->mask_port_map which has a bit set for each enabled port. Update ahci_platform_get_resources to ignore holes in the port numbers and enable ports defined in firmware by their reg property only. When firmware does not define children it is assumed that there is exactly one port, using index 0.

scsi: Rename .slave_alloc() and .slave_destroy()
Rename .slave_alloc() into .sdev_init() and .slave_destroy() into .sdev_destroy(). The new names make it clear that these are actions on SCSI devices. Make this change in the SCSI core, SCSI drivers and also in the ATA drivers. No functionality has been changed. This patch has been created as follows: * Change the text "slave_alloc" into "sdev_init" in all source files except those in drivers/net/ and Documentation/. * Change the text "slave_destroy" into "sdev_destroy" in all source files except those in drivers/net/ and Documentation/. * Rename lpfc_no_slave() into lpfc_no_sdev(). * Manually adjust whitespace where necessary to restore vertical alignment (dc395x driver and include/linux/libata.h).

Pull PCI updates from Bjorn Helgaas:
"Enumeration:
- Make pci_stop_dev() and pci_destroy_dev() safe so concurrent
callers can't stop a device multiple times, even as we migrate from
the global pci_rescan_remove_lock to finer-grained locking (Keith
Busch)
- Improve pci_walk_bus() implementation by making it recursive and
moving locking up to avoid need for a 'locked' parameter (Keith
Busch)
- Unexport pci_walk_bus_locked(), which is only used internally by
the PCI core (Keith Busch)
- Detect some Thunderbolt chips that are built-in and hence
'trustworthy' by a heuristic since the 'ExternalFacingPort' and
'usb4-host-interface' ACPI properties are not quite enough (Esther
Shimanovich)
Resource management:
- Use PCI bus addresses (not CPU addresses) in 'ranges' properties
when building dynamic DT nodes so systems where PCI and CPU
addresses differ work correctly (Andrea della Porta)
- Tidy resource sizing and assignment with helpers to reduce
redundancy (Ilpo Järvinen)
- Improve pdev_sort_resources() 'bogus alignment' warning to be more
specific (Ilpo Järvinen)
Driver binding:
- Convert driver .remove_new() callbacks to .remove() again to finish
the conversion from returning 'int' to being 'void' (Sergio
Paracuellos)
- Export pcim_request_all_regions(), a managed interface to request
all BARs (Philipp Stanner)
- Replace pcim_iomap_regions_request_all() with
pcim_request_all_regions(), and pcim_iomap_table()[n] with
pcim_iomap(n), in the following drivers: ahci, crypto qat, crypto
octeontx2, intel_th, iwlwifi, ntb idt, serial rp2, ALSA korg1212
(Philipp Stanner)
- Remove the now unused pcim_iomap_regions_request_all() (Philipp
Stanner)
- Export pcim_iounmap_region(), a managed interface to unmap and
release a PCI BAR (Philipp Stanner)
- Replace pcim_iomap_regions(mask) with pcim_iomap_region(n), and
pcim_iounmap_regions(mask) with pcim_iounmap_region(n), in the
following drivers: fpga dfl-pci, block mtip32xx, gpio-merrifield,
cavium (Philipp Stanner)
Error handling:
- Add sysfs 'reset_subordinate' to reset the entire hierarchy below a
bridge; previously Secondary Bus Reset could only be used when
there was a single device below a bridge (Keith Busch)
- Warn if we reset a running device where the driver didn't register
pci_error_handlers notification callbacks (Keith Busch)
ASPM:
- Disable ASPM L1 before touching L1 PM Substates to follow the spec
closer and avoid a CPU load timeout on some platforms (Ajay
Agarwal)
- Set devices below Intel VMD to D0 before enabling ASPM L1 Substates
as required per spec for all L1 Substates changes (Jian-Hong Pan)
Power management:
- Enable starfive controller runtime PM before probing host bridge
(Mayank Rana)
- Enable runtime power management for host bridges (Krishna chaitanya
chundru)
Power control:
- Use of_platform_device_create() instead of of_platform_populate()
to create pwrctl platform devices so we can control it based on the
child nodes (Manivannan Sadhasivam)
- Create pwrctrl platform devices only if there's a relevant power
supply property (Manivannan Sadhasivam)
- Add device link from the pwrctl supplier to the PCI dev to ensure
pwrctl drivers are probed before the PCI dev driver; this avoids a
race where pwrctl could change device power state while the PCI
driver was active (Manivannan Sadhasivam)
- Find pwrctl device for removal with of_find_device_by_node()
instead of searching all children of the parent (Manivannan
Sadhasivam)
- Rename 'pwrctl' to 'pwrctrl' to match new bandwidth controller
('bwctrl') and hotplug files (Bjorn Helgaas)
Bandwidth control:
- Add read/modify/write locking for Link Control 2, which is used to
manage Link speed (Ilpo Järvinen)
- Extract Link Bandwidth Management Status check into
pcie_lbms_seen(), where it can be shared between the bandwidth
controller and quirks that use it to help retrain failed links
(Ilpo Järvinen)
- Re-add Link Bandwidth notification support with updates to address
the reasons it was previously reverted (Alexandru Gagniuc, Ilpo
Järvinen)
- Add pcie_set_target_speed() and related functionality so drivers
can manage PCIe Link speed based on thermal or other constraints
(Ilpo Järvinen)
- Add a thermal cooling driver to throttle PCIe Links via the
existing thermal management framework (Ilpo Järvinen)
- Add a userspace selftest for the PCIe bandwidth controller (Ilpo
Järvinen)
PCI device hotplug:
- Add hotplug controller driver for Marvell OCTEON multi-function
device where function 0 has a management console interface to
enable/disable and provision various personalities for the other
functions (Shijith Thotton)
- Retain a reference to the pci_bus for the lifetime of a pci_slot to
avoid a use-after-free when the thunderbolt driver resets USB4 host
routers on boot, causing hotplug remove/add of downstream docks or
other devices (Lukas Wunner)
- Remove unused cpcihp struct cpci_hp_controller_ops.hardware_test
(Guilherme Giacomo Simoes)
- Remove unused cpqphp struct ctrl_dbg.ctrl (Christophe JAILLET)
- Use pci_bus_read_dev_vendor_id() instead of hand-coded presence
detection in cpqphp (Ilpo Järvinen)
- Simplify cpqphp enumeration, which is already simple-minded and
doesn't handle devices below hot-added bridges (Ilpo Järvinen)
Virtualization:
- Add ACS quirk for Wangxun FF5xxx NICs, which don't advertise an ACS
capability but do isolate functions as though PCI_ACS_RR and
PCI_ACS_CR were set, so the functions can be in independent IOMMU
groups (Mengyuan Lou)
TLP Processing Hints (TPH):
- Add and document TLP Processing Hints (TPH) support so drivers can
enable and disable TPH and the kernel can save/restore TPH
configuration (Wei Huang)
- Add TPH Steering Tag support so drivers can retrieve Steering Tag
values associated with specific CPUs via an ACPI _DSM to improve
performance by directing DMA writes closer to their consumers (Wei
Huang)
Data Object Exchange (DOE):
- Wait up to 1 second for DOE Busy bit to clear before writing a
request to the mailbox to avoid failures if the mailbox is still
busy from a previous transfer (Gregory Price)
Endpoint framework:
- Skip attempts to allocate from endpoint controller memory window if
the requested size is larger than the window (Damien Le Moal)
- Add and document pci_epc_mem_map() and pci_epc_mem_unmap() to
handle controller-specific size and alignment constraints, and add
test cases to the endpoint test driver (Damien Le Moal)
- Implement dwc pci_epc_ops.align_addr() so pci_epc_mem_map() can
observe DWC-specific alignment requirements (Damien Le Moal)
- Synchronously cancel command handler work in endpoint test before
cleaning up DMA and BARs (Damien Le Moal)
- Respect endpoint page size in dw_pcie_ep_align_addr() (Niklas
Cassel)
- Use dw_pcie_ep_align_addr() in dw_pcie_ep_raise_msi_irq() and
dw_pcie_ep_raise_msix_irq() instead of open coding the equivalent
(Niklas Cassel)
- Avoid NULL dereference if Modem Host Interface Endpoint lacks
'mmio' DT property (Zhongqiu Han)
- Release PCI domain ID of Endpoint controller parent (not controller
itself) and before unregistering the controller, to avoid
use-after-free (Zijun Hu)
- Clear secondary (not primary) EPC in pci_epc_remove_epf() when
removing the secondary controller associated with an NTB (Zijun Hu)
Cadence PCIe controller driver:
- Lower severity of 'phy-names' message (Bartosz Wawrzyniak)
Freescale i.MX6 PCIe controller driver:
- Fix suspend/resume support on i.MX6QDL, which has a hardware
erratum that prevents use of L2 (Stefan Eichenberger)
Intel VMD host bridge driver:
- Add 0xb60b and 0xb06f Device IDs for client SKUs (Nirmal Patel)
MediaTek PCIe Gen3 controller driver:
- Update mediatek-gen3 DT binding to require the exact number of
clocks for each SoC (Fei Shao)
- Add support for DT 'max-link-speed' and 'num-lanes' properties to
restrict the link speed and width (AngeloGioacchino Del Regno)
Microchip PolarFlare PCIe controller driver:
- Add DT and driver support for using either of the two PolarFire
Root Ports (Conor Dooley)
NVIDIA Tegra194 PCIe controller driver:
- Move endpoint controller cleanups that depend on refclk from the
host to the notifier that tells us the host has deasserted PERST#,
when refclk should be valid (Manivannan Sadhasivam)
Qualcomm PCIe controller driver:
- Add qcom SAR2130P DT binding with an additional clock (Dmitry
Baryshkov)
- Enable MSI interrupts if 'global' IRQ is supported, since a
previous commit unintentionally masked them (Manivannan Sadhasivam)
- Move endpoint controller cleanups that depend on refclk from the
host to the notifier that tells us the host has deasserted PERST#,
when refclk should be valid (Manivannan Sadhasivam)
- Add DT binding and driver support for IPQ9574, with Synopsys IP
v5.80a and Qcom IP 1.27.0 (devi priya)
- Move the OPP "operating-points-v2" table from the
qcom,pcie-sm8450.yaml DT binding to qcom,pcie-common.yaml, where it
can be used by other Qcom platforms (Qiang Yu)
- Add 'global' SPI interrupt for events like link-up, link-down to
qcom,pcie-x1e80100 DT binding so we can start enumeration when the
link comes up (Qiang Yu)
- Disable ASPM L0s for qcom,pcie-x1e80100 since the PHY is not tuned
to support this (Qiang Yu)
- Add ops_1_21_0 for SC8280X family SoC, which doesn't use the
'iommu-map' DT property and doesn't need BDF-to-SID translation
(Qiang Yu)
Rockchip PCIe controller driver:
- Define ROCKCHIP_PCIE_AT_SIZE_ALIGN to replace magic 256 endpoint
.align value (Damien Le Moal)
- When unmapping an endpoint window, compute the region index instead
of searching for it, and verify that the address was mapped (Damien
Le Moal)
- When mapping an endpoint window, verify that the address hasn't
been mapped already (Damien Le Moal)
- Implement pci_epc_ops.align_addr() for rockchip-ep (Damien Le Moal)
- Fix MSI IRQ data mapping to observe the alignment constraint, which
fixes intermittent page faults in memcpy_toio() and memcpy_fromio()
(Damien Le Moal)
- Rename rockchip_pcie_parse_ep_dt() to
rockchip_pcie_ep_get_resources() for consistency with similar DT
interfaces (Damien Le Moal)
- Skip the unnecessary link train in rockchip_pcie_ep_probe() and do
it only in the endpoint start operation (Damien Le Moal)
- Implement pci_epc_ops.stop_link() to disable link training and
controller configuration (Damien Le Moal)
- Attempt link training at 5 GT/s when both partners support it
(Damien Le Moal)
- Add a handler for PERST# signal so we can detect host-initiated
resets and start link training after PERST# is deasserted (Damien
Le Moal)
Synopsys DesignWare PCIe controller driver:
- Clear outbound address on unmap so dw_pcie_find_index() won't match
an ATU index that was already unmapped (Damien Le Moal)
- Use of_property_present() instead of of_property_read_bool() when
testing for presence of non-boolean DT properties (Rob Herring)
- Advertise 1MB size if endpoint supports Resizable BARs, which was
inadvertently lost in v6.11 (Niklas Cassel)
TI J721E PCIe driver:
- Add PCIe support for J722S SoC (Siddharth Vadapalli)
- Delay PCIE_T_PVPERL_MS (100 ms), not just PCIE_T_PERST_CLK_US (100
us), before deasserting PERST# to ensure power and refclk are
stable (Siddharth Vadapalli)
TI Keystone PCIe controller driver:
- Set the 'ti,keystone-pcie' mode so v3.65a devices work in Root
Complex mode (Kishon Vijay Abraham I)
- Try to avoid unrecoverable SError for attempts to issue config
transactions when the link is down; this is racy but the best we
can do (Kishon Vijay Abraham I)
Miscellaneous:
- Reorganize kerneldoc parameter names to match order in function
signature (Julia Lawall)
- Fix sysfs reset_method_store() memory leak (Todd Kjos)
- Simplify pci_create_slot() (Ilpo Järvinen)
- Fix incorrect printf format specifiers in pcitest (Luo Yifan)"

ata: libata-scsi: Return residual for emulated SCSI commands
The function ata_scsi_rbuf_fill() used to fill the reply buffer of emulated SCSI commands always copies the ATA reply buffer (ata_scsi_rbuf) up to the size of the SCSI command buffer (the transfer length for the command), even if the reply is shorter than the SCSI command buffer. This leads to issuers of the SCSI command to always get a result without any residual (resid is always 0) despite the potentially shorter reply for the command. Modify all fill actors used by ata_scsi_rbuf_fill() to return the number of bytes filled for the reply and 0 in case of error. Using this value, add a call to scsi_set_resid() in ata_scsi_rbuf_fill() to set the correct residual for the SCSI command when the reply length is shorter than the command buffer.

ata: libata-scsi: Remove struct ata_scsi_args
The data structure struct ata_scsi_args is used to pass the target ATA device, the SCSI command to simulate and the device identification data to ata_scsi_rbuf_fill() and to its actor function. This method of passing information does not improve the code in any way and in fact increases the number of pointer dereferences for no gains. Drop this data structure by modifying the interface of ata_scsi_rbuf_fill() and its actor function to take an ATA device and a SCSI command as argument.
