PCI/IDE: Fix reading a wrong reg for unused sel stream initialization
During pci_ide_init(), it will write PCI_ID_RESERVED_STREAM_ID into all
unused selective IDE stream blocks. In a selective IDE stream block, IDE
stream ID field is in selective IDE stream control register instead of
selective IDE stream capability register.

PCI/IDE: Fix off by one error calculating VF RID range
The VF ID range of an SR-IOV device is [0, num_VFs - 1].
pci_ide_stream_alloc() mistakenly uses num_VFs to represent the last ID.

Revert "PCI/TSM: Report active IDE streams"
The proposed ABI failed to account for multiple host bridges with the same stream name. The fix needs to namespace streams or otherwise link back to the host bridge, but a change like that is too big for a fix. Given this ABI never saw a released kernel, delete it for now and bring it back later with this issue addressed.

soc: fixes for 6.19
The main code change is a revert of the Raspberry Pi RP1 overlay
support that was decided to not be ready.
The other fixes are all for devicetree sources:
- ethernet configuration on ixp42x-actiontec-mi424wr is
board revision specific
- validation warning fixes for imx27/imx51/imx6, hikey960 and k3
- Minor corrections across imx8 boards, addressing all types of
issues with interrups, dma, ethernet and clock settings, all
simple one-line changes.

PCI/VGA: Don't assume the only VGA device on a system is boot_vga
Some systems ship with multiple display class devices but not all
of them are VGA devices. If the "only" VGA device on the system is not
used for displaying the image on the screen marking it as `boot_vga`
because nothing was found is totally wrong.
This behavior actually leads to mistakes of the wrong device being
advertised to userspace and then userspace can make incorrect decisions.
As there is an accurate `boot_display` sysfs file stop lying about
`boot_vga` by assuming if nothing is found it's the right device.

PCI: meson: Report that link is up while in ASPM L0s and L1 states
Previously meson_pcie_link_up() only returned true if the link was in the
L0 state. This was incorrect because hardware autonomously manages
transitions between L0, L0s, and L1 while both components on the link stay
in D0. Those states should all be treated as "link is active".
Returning false when the device was in L0s or L1 broke config accesses
because dw_pcie_other_conf_map_bus() fails if the link is down, which
caused errors like this:
meson-pcie fc000000.pcie: error: wait linkup timeout
pci 0000:01:00.0: BAR 0: error updating (0xfc700004 != 0xffffffff)
Remove the LTSSM state check, timeout, speed check, and error message from
meson_pcie_link_up(), the dw_pcie_ops.link_up() method, so it is a simple
boolean check of whether the link is active. Timeouts and error messages
are handled at a higher level, e.g., dw_pcie_wait_for_link().

PCI: qcom: Remove ASPM L0s support for MSM8996 SoC
Though I couldn't confirm ASPM L0s support with the Qcom hardware team, a bug report from Dmitry suggests that L0s is broken on this legacy SoC. Hence, remove L0s support from the Root Port Link Capabilities in this SoC. Since qcom_pcie_clear_aspm_l0s() is now used by more than one SoC config, call it from qcom_pcie_host_init() instead.

misc: rp1: drop overlay support
The RP1 driver can load an overlay at runtime to describe the inner peripherals. This has led to a lot of confusion regarding the naming of nodes, their topology and the reclaiming of related node resources. Since the overlay is currently not fully functional, drop its support in the driver in favor of the fully described static DT. This also means that this driver does not depend on CONFIG_PCI_DYNAMIC_OF_NODES and no longer requires PCI quirks to dynamically create the intermediate PCI nodes.

Significant patch series in this pull request:
- The 6 patch series "panic: sys_info: Refactor and fix a potential
issue" from Andy Shevchenko fixes a build issue and does some cleanup in
ib/sys_info.c.
- The 9 patch series "Implement mul_u64_u64_div_u64_roundup()" from
David Laight enhances the 64-bit math code on behalf of a PWM driver and
beefs up the test module for these library functions.
- The 2 patch series "scripts/gdb/symbols: make BPF debug info available
to GDB" from Ilya Leoshkevich makes BPF symbol names, sizes, and line
numbers available to the GDB debugger.
- The 4 patch series "Enable hung_task and lockup cases to dump system
info on demand" from Feng Tang adds a sysctl which can be used to cause
additional info dumping when the hung-task and lockup detectors fire.
- The 6 patch series "lib/base64: add generic encoder/decoder, migrate
users" from Kuan-Wei Chiu adds a general base64 encoder/decoder to lib/
and migrates several users away from their private implementations.
- The 2 patch series "rbree: inline rb_first() and rb_last()" from Eric

Live Update Orchestrator (LUO), and possibly for other future clients.
- The 13 patch series "kho: simplify state machine and enable dynamic
updates" from Pasha Tatashin increases the flexibility of KEXEC
Handover. Also preparation for LUO.
- The 18 patch series "Live Update Orchestrator" from Pasha Tatashin is
a major new feature targeted at cloud environments. Quoting the [0/N]:
This series introduces the Live Update Orchestrator, a kernel subsystem
designed to facilitate live kernel updates using a kexec-based reboot.
This capability is critical for cloud environments, allowing hypervisors
to be updated with minimal downtime for running virtual machines. LUO
achieves this by preserving the state of selected resources, such as
memory, devices and their dependencies, across the kernel transition.
As a key feature, this series includes support for preserving memfd file
descriptors, which allows critical in-memory data, such as guest RAM or
any other large memory region, to be maintained in RAM across the kexec
reboot.
Mike Rappaport merits a mention here, for his extensive review and
testing work.
- The 3 patch series "kexec: reorganize kexec and kdump sysfs" from
Sourabh Jain moves the kexec and kdump sysfs entries from /sys/kernel/
to /sys/kernel/kexec/ and adds back-compatibility symlinks which can
hopefully be removed one day.
- The 2 patch series "kho: fixes for vmalloc restoration" from Mike
Rapoport fixes a BUG which was being hit during KHO restoration of
vmalloc() regions.

- "Live Update Orchestrator" (Pasha Tatashin)
is a major new feature targeted at cloud environments. Quoting the
cover letter:
This series introduces the Live Update Orchestrator, a kernel
subsystem designed to facilitate live kernel updates using a
kexec-based reboot. This capability is critical for cloud
environments, allowing hypervisors to be updated with minimal
downtime for running virtual machines. LUO achieves this by
preserving the state of selected resources, such as memory,
devices and their dependencies, across the kernel transition.
As a key feature, this series includes support for preserving
memfd file descriptors, which allows critical in-memory data, such
as guest RAM or any other large memory region, to be maintained in
RAM across the kexec reboot.
Mike Rappaport merits a mention here, for his extensive review and
testing work.

Merge tag 'tsm-for-6.19' of git://git.kernel.org/pub/scm/linux/kernel/git/devsec/tsm
Pull PCIe Link Encryption and Device Authentication from Dan Williams:
"New PCI infrastructure and one architecture implementation for PCIe
link encryption establishment via platform firmware services.
This work is the result of multiple vendors coming to consensus on
some core infrastructure (thanks Alexey, Yilun, and Aneesh!), and
three vendor implementations, although only one is included in this
pull. The PCI core changes have an ack from Bjorn, the crypto/ccp/
changes have an ack from Tom, and the iommu/amd/ changes have an ack
from Joerg.
PCIe link encryption is made possible by the soup of acronyms
mentioned in the shortlog below. Link Integrity and Data Encryption
(IDE) is a protocol for installing keys in the transmitter and
receiver at each end of a link. That protocol is transported over Data
Object Exchange (DOE) mailboxes using PCI configuration requests.
The aspect that makes this a "platform firmware service" is that the
key provisioning and protocol is coordinated through a Trusted
Execution Envrionment (TEE) Security Manager (TSM). That is either
firmware running in a coprocessor (AMD SEV-TIO), or quasi-hypervisor
software (Intel TDX Connect / ARM CCA) running in a protected CPU
mode.
Now, the only reason to ask a TSM to run this protocol and install the
keys rather than have a Linux driver do the same is so that later, a
confidential VM can ask the TSM directly "can you certify this
device?".
That precludes host Linux from provisioning its own keys, because host
Linux is outside the trust domain for the VM. It also turns out that
all architectures, save for one, do not publish a mechanism for an OS
to establish keys in the root port. So "TSM-established link
encryption" is the only cross-architecture path for this capability
for the foreseeable future.
This unblocks the other arch implementations to follow in v6.20/v7.0,
once they clear some other dependencies, and it unblocks the next
phase of work to implement the end-to-end flow of confidential device
assignment. The PCIe specification calls this end-to-end flow Trusted
Execution Environment (TEE) Device Interface Security Protocol
(TDISP).
In the meantime, Linux gets a link encryption facility which has
practical benefits along the same lines as memory encryption. It
authenticates devices via certificates and may protect against
interposer attacks trying to capture clear-text PCIe traffic.
Summary:
- Introduce the PCI/TSM core for the coordination of device
authentication, link encryption and establishment (IDE), and later
management of the device security operational states (TDISP).
Notify the new TSM core layer of PCI device arrival and departure
- Add a low level TSM driver for the link encryption establishment
capabilities of the AMD SEV-TIO architecture
- Add a library of helpers TSM drivers to use for IDE establishment
and the DOE transport
- Add skeleton support for 'bind' and 'guest_request' operations in
support of TDISP"

VFIO updates for v6.19-rc1
- Move libvfio selftest artifacts in preparation of more tightly
coupled integration with KVM selftests. (David Matlack)
- Fix comment typo in mtty driver. (Chu Guangqing)
- Support for new hardware revision in the hisi_acc vfio-pci variant
driver where the migration registers can now be accessed via the PF.
When enabled for this support, the full BAR can be exposed to the
user. (Longfang Liu)
- Fix vfio cdev support for VF token passing, using the correct size
for the kernel structure, thereby actually allowing userspace to
provide a non-zero UUID token. Also set the match token callback for
the hisi_acc, fixing VF token support for this this vfio-pci variant
driver. (Raghavendra Rao Ananta)
- Introduce internal callbacks on vfio devices to simplify and
consolidate duplicate code for generating VFIO_DEVICE_GET_REGION_INFO
data, removing various ioctl intercepts with a more structured
solution. (Jason Gunthorpe)
- Introduce dma-buf support for vfio-pci devices, allowing MMIO regions
to be exposed through dma-buf objects with lifecycle managed through
move operations. This enables low-level interactions such as a
vfio-pci based SPDK drivers interacting directly with dma-buf capable
RDMA devices to enable peer-to-peer operations. IOMMUFD is also now
able to build upon this support to fill a long standing feature gap
versus the legacy vfio type1 IOMMU backend with an implementation of
P2P support for VM use cases that better manages the lifecycle of the
P2P mapping. (Leon Romanovsky, Jason Gunthorpe, Vivek Kasireddy)
- Convert eventfd triggering for error and request signals to use RCU
mechanisms in order to avoid a 3-way lockdep reported deadlock issue.
(Alex Williamson)
- Fix a 32-bit overflow introduced via dma-buf support manifesting with
large DMA buffers. (Alex Mastro)
- Convert nvgrace-gpu vfio-pci variant driver to insert mappings on
fault rather than at mmap time. This conversion serves both to make
use of huge PFNMAPs but also to both avoid corrected RAS events
during reset by now being subject to vfio-pci-core's use of
unmap_mapping_range(), and to enable a device readiness test after
reset. (Ankit Agrawal)
- Refactoring of vfio selftests to support multi-device tests and split
code to provide better separation between IOMMU and device objects.
This work also enables a new test suite addition to measure parallel
device initialization latency. (David Matlack)

data, removing various ioctl intercepts with a more structured
solution (Jason Gunthorpe)
- Introduce dma-buf support for vfio-pci devices, allowing MMIO regions
to be exposed through dma-buf objects with lifecycle managed through
move operations. This enables low-level interactions such as a
vfio-pci based SPDK drivers interacting directly with dma-buf capable
RDMA devices to enable peer-to-peer operations. IOMMUFD is also now
able to build upon this support to fill a long standing feature gap
versus the legacy vfio type1 IOMMU backend with an implementation of
P2P support for VM use cases that better manages the lifecycle of the
P2P mapping (Leon Romanovsky, Jason Gunthorpe, Vivek Kasireddy)
- Convert eventfd triggering for error and request signals to use RCU
mechanisms in order to avoid a 3-way lockdep reported deadlock issue
(Alex Williamson)
- Fix a 32-bit overflow introduced via dma-buf support manifesting with
large DMA buffers (Alex Mastro)
- Convert nvgrace-gpu vfio-pci variant driver to insert mappings on
fault rather than at mmap time. This conversion serves both to make
use of huge PFNMAPs but also to both avoid corrected RAS events
during reset by now being subject to vfio-pci-core's use of
unmap_mapping_range(), and to enable a device readiness test after
reset (Ankit Agrawal)
- Refactoring of vfio selftests to support multi-device tests and split
code to provide better separation between IOMMU and device objects.
This work also enables a new test suite addition to measure parallel
device initialization latency (David Matlack)

Williams)
- Switch vmd from custom domain number allocator to the common
allocator to prevent a potential race with new non-VMD buses (Dan
Williams)
- Enable Precision Time Measurement (PTM) only if device advertises
support for a relevant role, to prevent invalid PTM Requests that
cause ACS violations that are reported as AER Uncorrectable
Non-Fatal errors (Mika Westerberg)
Resource management:
- Prevent resource tree corruption when BAR resize fails (Ilpo
Järvinen)
- Restore BARs to the original size if a BAR resize fails (Ilpo
Järvinen)

save config state at hibernate so that state (not any earlier state
from enumeration, probe, or error recovery) will be restored when
resuming (Lukas Wunner)
- Save device config space on device addition, before driver binding,
so error recovery works more reliably (Lukas Wunner)
- Drop pci_save_state() from several drivers that no longer need it
since the PCI core always does it and pci_restore_state() no longer
invalidates the saved state (Lukas Wunner)
- Document use of pci_save_state() by drivers to capture the state
they want restored during error recovery (Lukas Wunner)
Power control:

Bruel)
Synopsys DesignWare PCIe controller driver:
- Clear L1 PM Substate Capability 'Supported' bits unless glue driver
says it's supported, which prevents users from enabling non-working
L1SS. Currently only qcom and tegra194 support L1SS (Bjorn Helgaas)
- Remove now-superfluous L1SS disable code from tegra194 (Bjorn
Helgaas)
- Configure L1SS support in dw-rockchip when DT says

Networking changes for 6.19.
Core & protocols
----------------
- Replace busylock at the Tx queuing layer with a lockless list. Resulting
in a 300% (4x) improvement on heavy TX workloads, sending twice the
number of packets per second, for half the cpu cycles.
- Allow constantly busy flows to migrate to a more suitable CPU/NIC
queue. Normally we perform queue re-selection when flow comes out
of idle, but under extreme circumstances the flows may be constantly
busy. Add sysctl to allow periodic rehashing even if it'd risk packet
reordering.
- Optimize the NAPI skb cache, make it larger, use it in more paths.
- Attempt returning Tx skbs to the originating CPU (like we already did
for Rx skbs).
- Various data structure layout and prefetch optimizations from Eric.
- Remove ktime_get() from the recvmsg() fast path, ktime_get() is sadly
quite expensive on recent AMD machines.
- Extend threaded NAPI polling to allow the kthread busy poll for packets.
- Make MPTCP use Rx backlog processing. This lowers the lock pressure,
improving the Rx performance.
- Support memcg accounting of MPTCP socket memory.
- Allow admin to opt sockets out of global protocol memory accounting
(using a sysctl or BPF-based policy). The global limits are a poor fit
for modern container workloads, where limits are imposed using cgroups.
- Improve heuristics for when to kick off AF_UNIX garbage collection.
- Allow users to control TCP SACK compression, and default to 33% of RTT.
- Add tcp_rcvbuf_low_rtt sysctl to let datacenter users avoid unnecessarily
aggressive rcvbuf growth and overshot when the connection RTT is low.
- Preserve skb metadata space across skb_push / skb_pull operations.
- Support for IPIP encapsulation in the nftables flowtable offload.
- Support appending IP interface information to ICMP messages (RFC 5837).
- Support setting max record size in TLS (RFC 8449).
- Remove taking rtnl_lock from RTM_GETNEIGHTBL and RTM_SETNEIGHTBL.
- Use a dedicated lock (and RCU) in MPLS, instead of rtnl_lock.
- Let users configure the number of write buffers in SMC.
- Add new struct sockaddr_unsized for sockaddr of unknown length,
from Kees.
- Some conversions away from the crypto_ahash API, from Eric Biggers.
- Some preparations for slimming down struct page.
- YAML Netlink protocol spec for WireGuard.
- Add a tool on top of YAML Netlink specs/lib for reporting commonly
computed derived statistics and summarized system state.

for 100BASE-T1 automotive Ethernet PHYs" specification.
- Add DPLL phase-adjust-gran pin attribute (and implement it in zl3073x).
- Refactor xfrm_input lock to reduce contention when NIC offloads IPsec
and performs RSS.
- Add info to devlink params whether the current setting is the default
or a user override. Allow resetting back to default.

Device drivers
--------------
- Add Motorcomm YT921x gigabit Ethernet switch support.
- Add MUCSE driver for N500/N210 1GbE NIC series.

Pull printk updates from Petr Mladek:
- Allow creaing nbcon console drivers with an unsafe write_atomic()
callback that can only be called by the final nbcon_atomic_flush_unsafe().
Otherwise, the driver would rely on the kthread.
It is going to be used as the-best-effort approach for an
experimental nbcon netconsole driver, see
https://lore.kernel.org/r/20251121-nbcon-v1-2-503d17b2b4af@debian.org
Note that a safe .write_atomic() callback is supposed to work in NMI
context. But some networking drivers are not safe even in IRQ
context:
https://lore.kernel.org/r/oc46gdpmmlly5o44obvmoatfqo5bhpgv7pabpvb6sjuqioymcg@gjsma3ghoz35
In an ideal world, all networking drivers would be fixed first and
the atomic flush would be blocked only in NMI context. But it brings
the question how reliable networking drivers are when the system is
in a bad state. They might block flushing more reliable serial
consoles which are more suitable for serious debugging anyway.
- Allow to use the last 4 bytes of the printk ring buffer.
- Prevent queuing IRQ work and block printk kthreads when consoles are
suspended. Otherwise, they create non-necessary churn or even block
the suspend.
- Release console_lock() between each record in the kthread used for
legacy consoles on RT. It might significantly speed up the boot.
- Release nbcon context between each record in the atomic flush. It
prevents stalls of the related printk kthread after it has lost the
ownership in the middle of a record
- Add support for NBCON consoles into KDB
- Add %ptsP modifier for printing struct timespec64 and use it where
possible
- Misc code clean up

Pull power management updates from Rafael Wysocki:
"There are quite a few interesting things here, including new hardware
support, new features, some bug fixes and documentation updates. In
addition, there are a usual bunch of minor fixes and cleanups all
over.
In the new hardware support category, there are intel_pstate and
intel_rapl driver updates to support new processors, Panther Lake,
Wildcat Lake, Noval Lake, and Diamond Rapids in the OOB mode, OPP and
bandwidth allocation support in the tegra186 cpufreq driver, and
JH7110S SOC support in dt-platdev cpufreq.
The new features are the PM QoS CPU latency limit for suspend-to-idle,
the netlink support for the energy model management, support for
terminating system suspend via a wakeup event during the sync of file
systems, configurable number of hibernation compression threads, the
runtime PM auto-cleanup macros, and the "poweroff" PM event that is
expected to be used during system shutdown.
Bugs are mostly fixed in cpuidle governors, but there are also fixes
elsewhere, like in the amd-pstate cpufreq driver.
Documentation updates include, but are not limited to, a new doc on
debugging shutdown hangs, cross-referencing fixes and cleanups in the
intel_pstate documentation, and updates of comments in the core
hibernation code.
Specifics:
- Introduce and document a QoS limit on CPU exit latency during
wakeup from suspend-to-idle (Ulf Hansson)

s390 updates for 6.19 merge window
- Provide a new interface for dynamic configuration and deconfiguration of hotplug memory, allowing with and without memmap_on_memory support. This makes the way memory hotplug is handled on s390 much more similar to other architectures - Remove compat support. There shouldn't be any compat user space around anymore, therefore get rid of a lot of code which also doesn't need to be tested anymore - Add stackprotector support. GCC 16 will get new compiler options, which allow to generate code required for kernel stackprotector support - Merge pai_crypto and pai_ext PMU drivers into a new driver. This removes a lot of duplicated code. The new driver is also extendable and allows to support new PMUs - Add driver override support for AP queues - Rework and extend zcrypt and AP trace events to allow for tracing of crypto requests - Support block sizes larger than 65535 bytes for CCW tape devices - Since the rework of the virtual kernel address space the module area and the kernel image are within the same 4GB area. This eliminates the need of weak per cpu variables. Get rid of ARCH_MODULE_NEEDS_WEAK_PER_CPU - Various other small improvements and fixes -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEECMNfWEw3SLnmiLkZIg7DeRspbsIFAmktZioACgkQIg7DeRsp bsK4Rw//VzkvHyzOtGKZ8Hb4S+Sh/PFlaZQXNhj+Xt5gWoOhP1uPmmhBe6LxjYaB J9Ns3hpONQ1dTHV7VVkds8FvM/SBcGe8m5RpefmChC/bjm5UEOV/MppKtA0aLnEH hJmdubIrrRAXKggxlHEfRLzBsFvV/rJ9Xf16FhRxGDc4pgmgkI1NPQ41/dyCHklQ dB3YrFVPIETywVYYVB/G3h11JgF5Z6CKtjYCdSx72Fkbj65+6JPfcPgLKMpcJuPd UxUXtCo1FCXlP70jsz8JQI8cdieG0KDQTtnZP4P/pqjQ3wirOqvMewNa9t9xmQ2e p6Rc1Vx5DESkq9bRWtQEaprTVVzK7DDLH3RuZwB+uLrcLGD8JvVS6/m9n9CgzBMT BnJXG2sLZH+gdQy+DSD/fVDD7OvIk8TGrH+OFwVIKhrT/J3B2E7ZSYyZZCNIS7VG yiuypoDGYg3ZpYjH9+qOXWB3nc0vQWrlFzb1bsQu1omJGmunLv4jtTjAKGN82C33 auBsIYAlQW20X7DV0vZa59PwqwtBqtdQQcTidwtSztzKogRXAdK8KKHtN60JM4S2 7sWFOFCQaTChAeDNw6MF5EtULb551nwH2RtJ9x3CrJj+OGK6clbQNcxIA7Oy0veR Sl9v1lMfeKOgDrPdDy3ArQBJ8WLlF9qX9wLKbiaNyIKmkz2ymkg= =CNrb -----END PGP SIGNATURE----- Merge tag 's390-6.19-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux Pull s390 updates from Heiko Carstens: - Provide a new interface for dynamic configuration and deconfiguration of hotplug memory, allowing with and without memmap_on_memory support.
