git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 updates from Will Deacon:
"ACPI:
- Improve error reporting when failing to manage SDEI on AGDI device
removal
Assembly routines:
- Improve register constraints so that the compiler can make use of
the zero register instead of moving an immediate #0 into a GPR
- Allow the compiler to allocate the registers used for CAS
instructions
CPU features and system registers:
- Cleanups to the way in which CPU features are identified from the
ID register fields
- Extend system register definition generation to handle Enum types
when defining shared register fields
- Generate definitions for new _EL2 registers and add new fields for
ID_AA64PFR1_EL1
- Allow SVE to be disabled separately from SME on the kernel
command-line
Tracing:
- Support for "direct calls" in ftrace, which enables BPF tracing for
arm64
Kdump:
- Don't bother unmapping the crashkernel from the linear mapping,
which then allows us to use huge (block) mappings and reduce TLB
pressure when a crashkernel is loaded.
Memory management:
- Try again to remove data cache invalidation from the coherent DMA
allocation path
- Simplify the fixmap code by mapping at page granularity
- Allow the kfence pool to be allocated early, preventing the rest of
the linear mapping from being forced to page granularity
Perf and PMU:
- Move CPU PMU code out to drivers/perf/ where it can be reused by
the 32-bit ARM architecture when running on ARMv8 CPUs
- Fix race between CPU PMU probing and pKVM host de-privilege
- Add support for Apple M2 CPU PMU
- Adjust the generic PERF_COUNT_HW_BRANCH_INSTRUCTIONS event
dynamically, depending on what the CPU actually supports
- Minor fixes and cleanups to system PMU drivers
Stack tracing:
- Use the XPACLRI instruction to strip PAC from pointers, rather than
rolling our own function in C
- Remove redundant PAC removal for toolchains that handle this in
their builtins
- Make backtracing more resilient in the face of instrumentation
Miscellaneous:
- Fix single-step with KGDB
- Remove harmless warning when 'nokaslr' is passed on the kernel
command-line
- Minor fixes and cleanups across the board"

Pull ARM SoC devicetree updates from Arnd Bergmann:
"The devicetree changes overall are again dominated by the Qualcomm
Snapdragon platform that weighs in at over 300 changesets, but there
are many updates across other platforms as well, notably Mediatek,
NXP, Rockchips, Renesas, TI, Samsung and ST Microelectronics. These
all add new features for existing machines, as well as new machines
and SoCs.
The newly added SoCs are:
- Allwinner T113-s, an Cortex-A7 based variant of the RISC-V based D1
chip.
- StarFive JH7110, a RISC-V SoC based on the Sifive U74 core like its
JH7100 predecessor, but with additional CPU cores and a GPU.
- Apple M2 as used in current Macbook Air/Pro and Mac Mini gets
added, with comparable support as its M1 predecessor.
- Unisoc UMS512 (Tiger T610) is a midrange smartphone SoC
- Qualcomm IPQ5332 and IPQ9574 are Wi-Fi 7 networking SoCs, based on
the Cortex-A53 and Cortex-A73 cores, respectively.
- Qualcomm sa8775p is an automotive SoC derived from the Snapdragon
family.
Including the initial board support for the added SoC platforms, there
are 52 new machines. The largest group are 19 boards industrial
embedded boards based on the NXP i.MX6 (32-bit) and i.MX8 (64-bit)
families.
Others include:
- Two boards based on the Allwinner f1c200s ultra-low-cost chip
- Three 'Banana Pi' variants based on the Amlogic g12b (A311D, S922X)
SoC.
- The Gl.Inet mv1000 router based on Marvell Armada 3720
- A Wifi/LTE Dongle based on Qualcomm msm8916
- Two robotics boards based on Qualcomm QRB chips
- Three Snapdragon based phones made by Xiaomi
- Five developments boards based on various Rockchip SoCs, including
the rk3588s-khadas-edge2 and a few NanoPi models
- The AM625 Beagleplay industrial SBC
Another 14 machines get removed: both boards for the obsolete 'oxnas'
platform, three boards for the Renesas r8a77950 SoC that were only for
pre-production chips, and various chromebook models based on the
Qualcomm Sc7180 'trogdor' design that were never part of products"

Pull ARM SoC updates from Arnd Bergmann:
"The Oxford Semiconductor OX810/OX820 'Oxnas' platform gets retired
after the ARM11MPcore processor keeps causing problems in certain
corner cases. OX820 was the only remaining SoC with this core after
CNS3xxx got retired, and its driver support was never completely
merged upstream. The Arm 'Realview' reference platform still supports
ARM11MPCore in principle, but this was never a product, and the CPU
support will get cleaned up later on.
Another series updates the mv78xx0 platform, which has been similarly
neglected for a while, but should work properly again now.
The other changes are minor cleanups across platforms, mostly
converting code to more modern interfaces for DT nodes and removing
some more code as a follow-up to the large-scale platform removal in
linux-6.3"

There is no need to have the functions blkif_get_x86_32_req() and
blkif_get_x86_64_req() in a header file, as they are used in one place
only.
So move them into the using source file and drop the inline qualifier.
While at it fix some style issues, and simplify the code by variable
reusing and using min() instead of open coding it.
Instead of using barrier() use READ_ONCE() for avoiding multiple reads
of nr_segments.

commit 4bd763568dbd ("HID: amd_sfh: Support for additional light sensor")
adds additional sensor devices, but forgets to add the number of HID
devices to match. Thus, the number of HID devices does not match the
actual number of sensors.
In order to prevent corruption and system hangs when more than the
allowed number of HID devices are accessed, the number of HID devices is
increased accordingly.

After failing to verify configuration, it returns directly without
releasing link, which may cause memory leak.
Paolo Abeni thinks that the whole code of this driver is quite
"suboptimal" and looks unmainatained since at least ~15y, so he
suggests that we could simply remove the whole driver, please
take it into consideration.
Simon Horman suggests that the fix label should be set to
"Linux-2.6.12-rc2" considering that the problem has existed
since the driver was introduced and the commit above doesn't
seem to exist in net/net-next.

devm_clk_get() will return either an error or NULL, which the driver
handles, continuing to use the clock of reading the value of the
clock-frequency property.
However, the value of ov5670->xvclk is left as-is and the other clock
framework functions aren't capable of handling error values.
Use devm_clk_get_optional() to obtain NULL instead of -ENOENT.

When the action of an xdp program was XDP_TX, lan966x was creating
a xdp_frame and use this one to send the frame back. But it is also
possible to send back the frame without needing a xdp_frame, because
it is possible to send it back using the page.
And then once the frame is transmitted is possible to use directly
page_pool_recycle_direct as lan966x is using page pools.
This would save some CPU usage on this path, which results in higher
number of transmitted frames. Bellow are the statistics:
Frame size: Improvement:
64 ~8%
256 ~11%
512 ~8%
1000 ~0%
1500 ~0%

Add support for XSK zero-copy to RX path. The setup of the XSK pool can
be done at runtime. If the netdev is running, then the queue must be
disabled and enabled during reconfiguration. This can be done easily
with functions introduced in previous commits.
A more important property is that, if the netdev is running, then the
setup of the XSK pool shall not stop the netdev in case of errors. A
broken netdev after a failed XSK pool setup is bad behavior. Therefore,
the allocation and setup of resources during XSK pool setup is done only
before any queue is disabled. Additionally, freeing and later allocation
of resources is eliminated in some cases. Page pool entries are kept for
later use. Two memory models are registered in parallel. As a result,
the XSK pool setup cannot fail during queue reconfiguration.
In contrast to other drivers, XSK pool setup and XDP BPF program setup
are separate actions. XSK pool setup can be done without any XDP BPF
program. The XDP BPF program can be added, removed or changed without
any reconfiguration of the XSK pool.
Test results with A53 1.2GHz:
xdpsock rxdrop copy mode, 64 byte frames:
pps pkts 1.00
rx 856,054 10,625,775
Two CPUs with both 100% utilization.

pps pkts 1.00
rx 889,388 4,615,284
Two CPUs with 100% and 20% utilization.
Packet rate increases and CPU utilization is reduced.
100% CPU load seems to the base load. This load is consumed by ksoftirqd
just for dropping the generated packets without xdpsock running.
Using batch API reduced CPU utilization slightly, but measurements are
not stable enough to provide meaningful numbers.

TX/RX ring size is static and power of 2 to enable compiler to optimize
modulo operation to mask operation. Make this optimization already in
the code and don't rely on the compiler.
CPU utilisation during high packet rate has not changed. So no
performance improvement has been measured. But it is best practice to
prevent modulo operations.
