Update links in the documentation and in-code comments which point to
the datasheet and schematic.
The current links don't work because National Semiconductor (which is
the manufacturer of this board and lm70) has been a part of Texas
Instruments since 2011 and hence http://www.national.com/ doesn't work
anymore.

The TP_STRUCT__entry that gets assigned the region name, or an
empty string if no region is present, is erroneously initialized
to the cxl_region pointer. It needs to be properly initialized
otherwise it's length is wrong and garbage chars can appear in
the kernel trace output: /sys/kernel/tracing/trace
The bad initialization was due in part to a naming conflict with
the parameter: struct cxl_region *region. The field 'region' is
already exposed externally as the region name, so changing that
to something logical, like 'region_name' is not an option. Instead
rename the internal only struct cxl_region to the commonly used
'cxlr'.
Impact is that tooling depending on that trace data can miss
picking up a valid event when searching by region name. The
TP_printk() output, if enabled, does emit the correct region
names in the dmesg log.
This was found during testing of the cxl-list option to report
media-errors for a region.

The __string() and __assign_str() helper macros of the TRACE_EVENT() macro
are going through some optimizations where only the source string of
__string() will be used and the __assign_str() source will be ignored and
later removed.
To make sure that there's no issues, a new check is added between the
__string() src argument and the __assign_str() src argument that does a
strcmp() to make sure they are the same string.
The hclgevf trace events have:
__assign_str(devname, &hdev->nic.kinfo.netdev->name);
Which triggers the warning:
hclgevf_trace.h:34:39: error: passing argument 1 of ‘strcmp’ from incompatible pointer type [-Werror=incompatible-pointer-types]
34 | __assign_str(devname, &hdev->nic.kinfo.netdev->name);
[..]
arch/x86/include/asm/string_64.h:75:24: note: expected ‘const char *’ but argument is of type ‘char (*)[16]’
75 | int strcmp(const char *cs, const char *ct);
| ~~~~~~~~~~~~^~
Because __assign_str() now has:
WARN_ON_ONCE(__builtin_constant_p(src) ? \
strcmp((src), __data_offsets.dst##_ptr_) : \
(src) != __data_offsets.dst##_ptr_); \
The problem is the '&' on hdev->nic.kinfo.netdev->name. That's because
that name is:
char name[IFNAMSIZ]
Where passing an address '&' of a char array is not compatible with strcmp().
The '&' is not necessary, remove it.

I'm working on improving the __assign_str() and __string() macros to be
more efficient, and removed some unneeded semicolons. This triggered a bug
in the build as some of the __assign_str() macros in intel_display_trace
was missing a terminating semicolon.

On MT7530, the HT_XTAL_FSEL field of the HWTRAP register stores a 2-bit
value that represents the frequency of the crystal oscillator connected to
the switch IC. The field is populated by the state of the ESW_P4_LED_0 and
ESW_P4_LED_0 pins, which is done right after reset is deasserted.
ESW_P4_LED_0 ESW_P3_LED_0 Frequency
-----------------------------------------
0 0 Reserved
0 1 20MHz
1 0 40MHz
1 1 25MHz
On MT7531, the XTAL25 bit of the STRAP register stores this. The LAN0LED0
pin is used to populate the bit. 25MHz when the pin is high, 40MHz when
it's low.
These pins are also used with LEDs, therefore, their state can be set to
something other than the bootstrapping configuration. For example, a link
may be established on port 3 before the DSA subdriver takes control of the
switch which would set ESW_P3_LED_0 to high.
Currently on mt7530_setup() and mt7531_setup(), 1000 - 1100 usec delay is
described between reset assertion and deassertion. Some switch ICs in real
life conditions cannot always have these pins set back to the bootstrapping
configuration before reset deassertion in this amount of delay. This causes
wrong crystal frequency to be selected which puts the switch in a
nonfunctional state after reset deassertion.
The tests below are conducted on an MT7530 with a 40MHz crystal oscillator
by Justin Swartz.
With a cable from an active peer connected to port 3 before reset, an
incorrect crystal frequency (0b11 = 25MHz) is selected:
[1] [3] [5]

[3] Reset is deasserted.
[4] Period of 315 usec. HWTRAP register is populated with incorrect
XTAL frequency.
[5] Signals reflect the bootstrapped configuration.
Increase the delay between reset_control_assert() and
reset_control_deassert(), and gpiod_set_value_cansleep(priv->reset, 0) and
gpiod_set_value_cansleep(priv->reset, 1) to 5000 - 5100 usec. This amount
ensures a higher possibility that the switch IC will have these pins back
to the bootstrapping configuration before reset deassertion.
With a cable from an active peer connected to port 3 before reset, the
correct crystal frequency (0b10 = 40MHz) is selected:

Commit d3256efd8e8b ("veth: allow enabling NAPI even without XDP") tried to fix
the fact that GRO was not possible without XDP, because veth did not use NAPI
without XDP. However, it also introduced the behaviour that GRO is always
enabled, when XDP is enabled.
While it might be desired for most cases, it is confusing for the user at best
as the GRO flag suddenly changes, when an XDP program is attached. It also
introduces some complexities in state management as was partially addressed in
commit fe9f801355f0 ("net: veth: clear GRO when clearing XDP even when down").
But the biggest problem is that it is not possible to disable GRO at all, when
an XDP program is attached, which might be needed for some use cases.
Fix this by not touching the GRO flag on XDP enable/disable as the code already
supports switching to NAPI if either GRO or XDP is requested.

RZ/G2L interrupt chips require that the interrupt is masked before changing
the NMI, IRQ, TINT interrupt settings. Aside of that, after setting an edge
trigger type it is required to clear the interrupt status register in order
to avoid spurious interrupts.
The current implementation fails to do either of that and therefore is
prone to generate spurious interrupts when setting the trigger type.
Address this by:
- Ensuring that the interrupt is masked at the chip level across the
update for the TINT chip
- Clearing the interrupt status register after updating the trigger mode
for edge type interrupts
[ tglx: Massaged changelog and reverted the spin_lock_irqsave() change as
the set_type() callback is always called with interrupts disabled. ]

The irq_eoi() callback of the RZ/G2L interrupt chip clears the relevant
interrupt cause bit in the TSCR register by writing to it.
This write is not sufficient because the write is posted and therefore not
guaranteed to immediately clear the bit. Due to that delay the CPU can
raise the just handled interrupt again.
Prevent this by reading the register back which causes the posted write to
be flushed to the hardware before the read completes.

When unbinding a user event channel, the related handler might be
called a last time in case the kernel was built with
CONFIG_DEBUG_SHIRQ. This might cause a WARN() in the handler.
Avoid that by adding an "unbinding" flag to struct user_event which
will short circuit the handler.

Pull CXL updates from Dan Williams:
"CXL has mechanisms to enumerate the performance characteristics of
memory devices. Those mechanisms allow Linux to build the equivalent
of ACPI SRAT, SLIT, and HMAT tables dynamically at runtime. That
capability is necessary because static ACPI can not represent dynamic
CXL configurations (and reconfigurations).
So, building on the v6.8 work to add "Quality of Service" enumeration,
this update plumbs CXL "access coordinates" (read/write access latency
and bandwidth) in all the same places that ACPI HMAT feeds similar
data. Follow-on patches from the -mm side can then use that data to
feed mechanisms like mm/memory-tiers.c. Greg has acked the touch to
drivers/base/.
The other feature update this cycle is support for CXL error injection
via the ACPI EINJ module. That facility enables injection of bus
protocol errors provided the user knows the magic address values to
insert in the interface. To hide that magic, and make this easier to
use, new error injection attributes were added to CXL debugfs. That
interface injects the errors relative to a CXL object rather than
require user tooling to know how to lookup and inject RCRB (Root
Complex Register Block) addresses into the raw EINJ debugfs interface.
It received some helpful review comments from Tony, but no explicit
acks from the ACPI side. The primary user visible change for existing
EINJ users is that they may find that einj.ko was already loaded by
cxl_core.ko. Previously, einj.ko was only loaded on demand.
The usual collection of miscellaneous cleanups are also present this
cycle.
Summary:
- Supplement ACPI HMAT reported memory performance with native CXL
memory performance enumeration
- Add support for CXL error injection via the ACPI EINJ mechanism
- Cleanup CXL DOE and CDAT integration
- Miscellaneous cleanups and fixes"

Pull VFIO updates from Alex Williamson:
- Add warning in unlikely case that device is not captured with
driver_override (Kunwu Chan)
- Error handling improvements in mlx5-vfio-pci to detect firmware
tracking object error states, logging of firmware error syndrom, and
releasing of firmware resources in aborted migration sequence (Yishai
Hadas)
- Correct an un-alphabetized VFIO MAINTAINERS entry (Alex Williamson)
- Make the mdev_bus_type const and also make the class struct const for
a couple of the vfio-mdev sample drivers (Ricardo B. Marliere)
- Addition of a new vfio-pci variant driver for the GPU of NVIDIA's
Grace-Hopper superchip. During initialization of the chip-to-chip
interconnect in this hardware module, the PCI BARs of the device
become unused in favor of a faster, coherent mechanism for exposing
device memory. This driver primarily changes the VFIO representation
of the device to masquerade this coherent aperture to replace the
physical PCI BARs for userspace drivers. This also incorporates use
of a new vma flag allowing KVM to use write combining attributes for
uncached device memory (Ankit Agrawal)
- Reset fixes and cleanups for the pds-vfio-pci driver. Save and
restore files were previously leaked if the device didn't pass
through an error state, this is resolved and later re-fixed to
prevent access to the now freed files. Reset handling is also
refactored to remove the complicated deferred reset mechanism (Brett
Creeley)
- Remove some references to pl330 in the vfio-platform amba driver
(Geert Uytterhoeven)
- Remove twice redundant and ugly code to unpin incidental pins of the
zero-page (Alex Williamson)
- Deferred reset logic is also removed from the hisi-acc-vfio-pci
driver as a simplification (Shameer Kolothum)
- Enforce that mlx5-vfio-pci devices must support PRE_COPY and remove
resulting unnecessary code. There is no device firmware that has been
available publicly without this support (Yishai Hadas)
- Switch over to using the .remove_new callback for vfio-platform in
support of the broader transition for a void remove function (Uwe
Kleine-König)
- Resolve multiple issues in interrupt code for VFIO bus drivers that
allow calling eventfd_signal() on a NULL context. This also remove a
potential race in INTx setup on certain hardware for vfio-pci, races
with various mechanisms to mask INTx, and leaked virqfds in

Pull kvm updates from Paolo Bonzini:
"S390:
- Changes to FPU handling came in via the main s390 pull request
- Only deliver to the guest the SCLP events that userspace has
requested
- More virtual vs physical address fixes (only a cleanup since
virtual and physical address spaces are currently the same)
- Fix selftests undefined behavior
x86:
- Fix a restriction that the guest can't program a PMU event whose
encoding matches an architectural event that isn't included in the
guest CPUID. The enumeration of an architectural event only says
that if a CPU supports an architectural event, then the event can
be programmed *using the architectural encoding*. The enumeration
does NOT say anything about the encoding when the CPU doesn't
report support the event *in general*. It might support it, and it
might support it using the same encoding that made it into the
architectural PMU spec
- Fix a variety of bugs in KVM's emulation of RDPMC (more details on
individual commits) and add a selftest to verify KVM correctly
emulates RDMPC, counter availability, and a variety of other
PMC-related behaviors that depend on guest CPUID and therefore are
easier to validate with selftests than with custom guests (aka
kvm-unit-tests)
- Zero out PMU state on AMD if the virtual PMU is disabled, it does
not cause any bug but it wastes time in various cases where KVM
would check if a PMC event needs to be synthesized
- Optimize triggering of emulated events, with a nice ~10%
performance improvement in VM-Exit microbenchmarks when a vPMU is
exposed to the guest
- Tighten the check for "PMI in guest" to reduce false positives if
an NMI arrives in the host while KVM is handling an IRQ VM-Exit
- Fix a bug where KVM would report stale/bogus exit qualification
information when exiting to userspace with an internal error exit
code
- Add a VMX flag in /proc/cpuinfo to report 5-level EPT support
- Rework TDP MMU root unload, free, and alloc to run with mmu_lock
held for read, e.g. to avoid serializing vCPUs when userspace
deletes a memslot
- Tear down TDP MMU page tables at 4KiB granularity (used to be
1GiB). KVM doesn't support yielding in the middle of processing a
zap, and 1GiB granularity resulted in multi-millisecond lags that
are quite impolite for CONFIG_PREEMPT kernels
- Allocate write-tracking metadata on-demand to avoid the memory
overhead when a kernel is built with i915 virtualization support
but the workloads use neither shadow paging nor i915 virtualization
- Explicitly initialize a variety of on-stack variables in the
emulator that triggered KMSAN false positives
- Fix the debugregs ABI for 32-bit KVM
- Rework the "force immediate exit" code so that vendor code
ultimately decides how and when to force the exit, which allowed
some optimization for both Intel and AMD
- Fix a long-standing bug where kvm_has_noapic_vcpu could be left
elevated if vCPU creation ultimately failed, causing extra
unnecessary work
- Cleanup the logic for checking if the currently loaded vCPU is
in-kernel
- Harden against underflowing the active mmu_notifier invalidation
count, so that "bad" invalidations (usually due to bugs elsehwere
in the kernel) are detected earlier and are less likely to hang the
kernel
x86 Xen emulation:
- Overlay pages can now be cached based on host virtual address,
instead of guest physical addresses. This removes the need to
reconfigure and invalidate the cache if the guest changes the gpa
but the underlying host virtual address remains the same
- When possible, use a single host TSC value when computing the
deadline for Xen timers in order to improve the accuracy of the
timer emulation
- Inject pending upcall events when the vCPU software-enables its
APIC to fix a bug where an upcall can be lost (and to follow Xen's
behavior)
- Fall back to the slow path instead of warning if "fast" IRQ
delivery of Xen events fails, e.g. if the guest has aliased xAPIC
IDs
RISC-V:
- Support exception and interrupt handling in selftests
- New self test for RISC-V architectural timer (Sstc extension)
- New extension support (Ztso, Zacas)
- Support userspace emulation of random number seed CSRs
ARM:
- Infrastructure for building KVM's trap configuration based on the
architectural features (or lack thereof) advertised in the VM's ID
registers
- Support for mapping vfio-pci BARs as Normal-NC (vaguely similar to
x86's WC) at stage-2, improving the performance of interacting with
assigned devices that can tolerate it
- Conversion of KVM's representation of LPIs to an xarray, utilized
to address serialization some of the serialization on the LPI
injection path
- Support for _architectural_ VHE-only systems, advertised through
the absence of FEAT_E2H0 in the CPU's ID register
- Miscellaneous cleanups, fixes, and spelling corrections to KVM and
selftests
LoongArch:
- Set reserved bits as zero in CPUCFG
- Start SW timer only when vcpu is blocking
- Do not restart SW timer when it is expired
- Remove unnecessary CSR register saving during enter guest
- Misc cleanups and fixes as usual
Generic:
- Clean up Kconfig by removing CONFIG_HAVE_KVM, which was basically
always true on all architectures except MIPS (where Kconfig
determines the available depending on CPU capabilities). It is
replaced either by an architecture-dependent symbol for MIPS, and
IS_ENABLED(CONFIG_KVM) everywhere else
- Factor common "select" statements in common code instead of
requiring each architecture to specify it
- Remove thoroughly obsolete APIs from the uapi headers
- Move architecture-dependent stuff to uapi/asm/kvm.h
- Always flush the async page fault workqueue when a work item is
being removed, especially during vCPU destruction, to ensure that
there are no workers running in KVM code when all references to
KVM-the-module are gone, i.e. to prevent a very unlikely
use-after-free if kvm.ko is unloaded
- Grab a reference to the VM's mm_struct in the async #PF worker
itself instead of gifting the worker a reference, so that there's
no need to remember to *conditionally* clean up after the worker
Selftests:
- Reduce boilerplate especially when utilize selftest TAP
infrastructure
- Add basic smoke tests for SEV and SEV-ES, along with a pile of
library support for handling private/encrypted/protected memory
- Fix benign bugs where tests neglect to close() guest_memfd files"

"MTD:
- The Carillo Ranch driver has been removed
- Top level mtd bindings have received a couple of improvements
(references, selects)
- The ssfdc driver received few minor adjustments
- The usual load of misc/small improvements and fixes
Raw NAND:
- The main series brought is an update of the Broadcom support to
support all BCMBCA SoCs and their specificity (ECC, write
protection, configuration straps), plus a few misc fixes and
changes in the main driver. Device tree updates are also part of
this PR, initially because of a misunderstanding on my side.
- The STM32_FMC2 controller driver is also upgraded to properly
support MP1 and MP25 SoCs.
- A new compatible is added for an Atmel flavor.
- Among all these feature changes, there is as well a load of
continuous read related fixes, avoiding more corner conditions and
clarifying the logic. Finally a few miscellaneous fixes are made to
the core, the lpx32xx_mlc, fsl_lbc, Meson and Atmel controller
driver, as well as final one in the Hynix vendor driver.
SPI-NAND:
- The ESMT support has been extended to match 5 bytes ID to avoid
collisions. Winbond support on its side receives support for
W25N04KV chips.
SPI NOR:
- SPI NOR gets the non uniform erase code cleaned. We stopped using
bitmasks for erase types and flags, and instead introduced
dedicated members. We then passed the SPI NOR erase map to MTD.
Users can now determine the erase regions and make informed
decisions on partitions size.

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk updates from Stephen Boyd:
"Not a ton of stuff happening in the clk framework. We got some more
devm helpers and we seem to be going in the direction of "just turn
this stuff on already and leave me alone!" with the addition of a
devm_clk_bulk_get_all_enable() API. I'm hoping that we can make that
into a pmdomain that drivers attach instead, but this API should help
drivers simplify in the meantime.
Outside of the devm wrappers, we've got the usual clk driver updates
that are dominated by the major phone SoC vendors (Samsung and
Qualcomm) and the non-critical driver fixes for things like incorrect
topology descriptions and wrong registers or bit fields. More details
are below, but I'd say that it looks pretty ordinary. The only thing
that really jumps out at me is the Renesas clk driver that's ignoring
clks that are assigned to remote processors in DeviceTree. That's a
new feature that they're using to avoid marking clks as
CLK_IGNORE_UNUSED based on the configuration of the system.
Core:
- Increase dev_id len for clkdev lookups
- Add a devm_clk_bulk_get_all_enable() API to get and enable all clks
for a device
- Add a devm variant of clk_rate_exclusive_get()
New Drivers:
- Display, TCSR, GPU, and Camera clock controllers for Qualcomm's X1
Elite SoC
- Google GS101 PERIC0 and PERIC1 clock controllers
- Exynos850 PDMA clocks
- Exynos850 CPU cluster 0 and 1 (CMU_CPUCLK0/CMU_CPUCLK1) clock
controllers
Removed Drivers:
- Remove the unused Qualcomm sc7180 modem clk driver
Updates:
- Fix some static checker errors in the Hisilicon clk driver
- Polarfire MSSPLL hardware has 4 output clocks (the driver supported
previously only one output); each of these 4 outputs feed dividers
and the output of each divider feed individual hardware blocks
(e.g. CAN, Crypto, eMMC); individual hardware block drivers need to
control their clocks thus clock driver support was added for all
MSSPLL output clocks
- Typo fixes in the Qualcomm IPQ5018 GCC driver
- Add "qdss_at" clk on Qualcomm IPQ6018, needed for WiFi
- Properly terminate frequency tables in different Qualcomm clk
drivers
- Add MDSS, crypto, and SDCC resets on Qualcomm MSM8953
- Add missing UFS CLKREF clks on Qualcomm SC8180X
- Avoid significant delays during boot by adding a softdep on rpmhpd

- Add QUPv3 RCGS w/ DFS and video resets to Qualcomm SM8150 GCC
driver
- Fix the custom GPU GX "do-nothing" method in the Qualcomm GDSC
driver
- Add an external regulator to GX GDSC on Qualcomm SC8280XP GPU clk
driver
- Switch display, GPU, video, and camera Qualcomm clk drivers to
module_platform_driver()
- Set a longer delay for Venus resets on many Qualcomm SoCs
- Correct the GDSC wait times in the Qualcomm SDM845 display clk
driver
- Fix clock listing Oops on Amlogic axg
- New pll-rate for Rockchip rk3568
- i2s rate improvements for Rockchip rk3399
- Rockchip rk3588 syscon clock fixes and removal of overall
clock-number from the rk3588 binding header
- A prerequisite for later improvements to the Rockchip rk3588 linked
clocks
- Minor clean-ups and error handling improvements in both
composite-8m and SCU i.MX clock drivers
- Fix for SAI_MCLK_SEL definition for i.MX8MP
- Register the Samsung CMU MISC clock controller earlier, so the
Multi Core Timer clocksource can use it on Google GS101
- Propagate Exynos850 SPI IPCLK rate change to parents, so the SPI
will get proper clock rates
- Refactor the generic Samsung CPU clock controllers code, preparing
it for supporting Exynos850 CPU clocks
- Fix some clk kerneldoc warnings
- Add Ethernet, SDHI, DMA, and HyperFLASH/QSPI (RPC-IF) clocks on
Renesas R-Car V4M

The EFI stub on x86 no longer invokes the decompressor as a subsequent
boot stage, but calls into the decompression code directly while running
in the context of the EFI boot services.
This means that when using the native EFI entrypoint (as opposed to the
EFI handover protocol, which clears BSS explicitly), the firmware PE
image loader is being relied upon to ensure that BSS is zeroed before
the EFI stub is entered from the firmware.
As Radek's report proves, this is a bad idea. Not all loaders do this
correctly, which means some global variables that should be statically
initialized to 0x0 may have junk in them.
So clear BSS explicitly when entering via efi_pe_entry(). Note that
zeroing BSS from C code is not generally safe, but in this case, the
following assignment and dereference of a global pointer variable
ensures that the memset() cannot be deferred or reordered.

Pull media updates from Mauro Carvalho Chehab:
- DVB budget legacy API was finally documented. It took only 20+ years
to get some documentation about it...
- hantro driver has gained support for STM32MP25 VDEC/VENC
- rkisp1 has gained support for i.MX8MP
- atomisp got rid of two items from its todo list. Still 5 items
pending for moving it out of staging
- lots of driver fixes, cleanups and improvements

Yu Chien Peter Lin <peterlin@andestech.com> says:
This patch series introduces the Andes PMU extension, which serves the
same purpose as Sscofpmf and Smcntrpmf. Its non-standard local interrupt
is assigned to bit 18 in the custom S-mode local interrupt enable and
pending registers (slie/slip), while the interrupt cause is (256 + 18).
