ARM:
* Move a lot of state that was previously stored on a per vcpu
basis into a per-CPU area, because it is only pertinent to the
host while the vcpu is loaded. This results in better state
tracking, and a smaller vcpu structure.
* Add full handling of the ERET/ERETAA/ERETAB instructions in
nested virtualisation. The last two instructions also require
emulating part of the pointer authentication extension.
As a result, the trap handling of pointer authentication has
been greatly simplified.
* Turn the global (and not very scalable) LPI translation cache
into a per-ITS, scalable cache, making non directly injected
LPIs much cheaper to make visible to the vcpu.
* A batch of pKVM patches, mostly fixes and cleanups, as the
upstreaming process seems to be resuming. Fingers crossed!
* Allocate PPIs and SGIs outside of the vcpu structure, allowing
for smaller EL2 mapping and some flexibility in implementing
more or less than 32 private IRQs.
* Purge stale mpidr_data if a vcpu is created after the MPIDR
map has been created.
* Preserve vcpu-specific ID registers across a vcpu reset.
* Various minor cleanups and improvements.
LoongArch:
* Add ParaVirt IPI support.
* Add software breakpoint support.
* Add mmio trace events support.
RISC-V:
* Support guest breakpoints using ebreak
* Introduce per-VCPU mp_state_lock and reset_cntx_lock
* Virtualize SBI PMU snapshot and counter overflow interrupts
* New selftests for SBI PMU and Guest ebreak
* Some preparatory work for both TDX and SNP page fault handling.
This also cleans up the page fault path, so that the priorities
of various kinds of fauls (private page, no memory, write
to read-only slot, etc.) are easier to follow.
x86:
* Minimize amount of time that shadow PTEs remain in the special
REMOVED_SPTE state. This is a state where the mmu_lock is held for
reading but concurrent accesses to the PTE have to spin; shortening
its use allows other vCPUs to repopulate the zapped region while
the zapper finishes tearing down the old, defunct page tables.
* Advertise the max mappable GPA in the "guest MAXPHYADDR" CPUID field,
which is defined by hardware but left for software use. This lets KVM
communicate its inability to map GPAs that set bits 51:48 on hosts
without 5-level nested page tables. Guest firmware is expected to
use the information when mapping BARs; this avoids that they end up at
a legal, but unmappable, GPA.
* Fixed a bug where KVM would not reject accesses to MSR that aren't
supposed to exist given the vCPU model and/or KVM configuration.
* As usual, a bunch of code cleanups.
x86 (AMD):
* Implement a new and improved API to initialize SEV and SEV-ES VMs, which
will also be extendable to SEV-SNP. The new API specifies the desired
encryption in KVM_CREATE_VM and then separately initializes the VM.
The new API also allows customizing the desired set of VMSA features;
the features affect the measurement of the VM's initial state, and
therefore enabling them cannot be done tout court by the hypervisor.
While at it, the new API includes two bugfixes that couldn't be
applied to the old one without a flag day in userspace or without
affecting the initial measurement. When a SEV-ES VM is created with
the new VM type, KVM_GET_REGS/KVM_SET_REGS and friends are
rejected once the VMSA has been encrypted. Also, the FPU and AVX
state will be synchronized and encrypted too.
* Support for GHCB version 2 as applicable to SEV-ES guests. This, once
more, is only accessible when using the new KVM_SEV_INIT2 flow for
initialization of SEV-ES VMs.
x86 (Intel):
* An initial bunch of prerequisite patches for Intel TDX were merged.
They generally don't do anything interesting. The only somewhat user
visible change is a new debugging mode that checks that KVM's MMU
never triggers a #VE virtualization exception in the guest.
* Clear vmcs.EXIT_QUALIFICATION when synthesizing an EPT Misconfig VM-Exit to
L1, as per the SDM.
Generic:
* Use vfree() instead of kvfree() for allocations that always use vcalloc()
or __vcalloc().
* Remove .change_pte() MMU notifier - the changes to non-KVM code are
small and Andrew Morton asked that I also take those through the KVM
tree. The callback was only ever implemented by KVM (which was also the
original user of MMU notifiers) but it had been nonfunctional ever since
calls to set_pte_at_notify were wrapped with invalidate_range_start
and invalidate_range_end... in 2012.
Selftests:
* Enhance the demand paging test to allow for better reporting and stressing
of UFFD performance.
* Convert the steal time test to generate TAP-friendly output.
* Fix a flaky false positive in the xen_shinfo_test due to comparing elapsed
time across two different clock domains.
* Skip the MONITOR/MWAIT test if the host doesn't actually support MWAIT.
* Avoid unnecessary use of "sudo" in the NX hugepage test wrapper shell
script, to play nice with running in a minimal userspace environment.
* Allow skipping the RSEQ test's sanity check that the vCPU was able to
complete a reasonable number of KVM_RUNs, as the assert can fail on a
completely valid setup. If the test is run on a large-ish system that is
otherwise idle, and the test isn't affined to a low-ish number of CPUs, the
vCPU task can be repeatedly migrated to CPUs that are in deep sleep states,
which results in the vCPU having very little net runtime before the next
migration due to high wakeup latencies.
* Define _GNU_SOURCE for all selftests to fix a warning that was introduced by
a change to kselftest_harness.h late in the 6.9 cycle, and because forcing
every test to #define _GNU_SOURCE is painful.
* Provide a global pseudo-RNG instance for all tests, so that library code can
generate random, but determinstic numbers.
* Use the global pRNG to randomly force emulation of select writes from guest
code on x86, e.g. to help validate KVM's emulation of locked accesses.
* Allocate and initialize x86's GDT, IDT, TSS, segments, and default exception
handlers at VM creation, instead of forcing tests to manually trigger the
related setup.
Documentation:
* Fix a goof in the KVM_CREATE_GUEST_MEMFD documentation.

Pull CXL updates from Dave Jiang:
- Three CXL mailbox passthrough commands are added to support the
populating and clearing of vendor debug logs:
- Get Log Capabilities
- Get Supported Log Sub-List Commands
- Clear Log
- Add support of Device Phyiscal Address (DPA) to Host Physical Address
(HPA) translation for CXL events of cxl_dram and cxl_general media.
This allows user space to figure out which CXL region the event
occured via trace event.
- Connect CXL to CPER reporting.
If a device is configured for firmware first, CXL event records are
not sent directly to the host. Those records are reported through EFI
Common Platform Error Records (CPER). Add support to route the CPER
records through the CXL sub-system in order to provide DPA to HPA
translation and also event decoding and tracing. This is useful for
users to determine which system issues may correspond to specific
hardware events.
- A number of misc cleanups and fixes:
- Fix for compile warning of cxl_security_ops
- Add debug message for invalid interleave granularity
- Enhancement to cxl-test event testing
- Add dev_warn() on unsupported mixed mode decoder
- Fix use of phys_to_target_node() for x86

PCI: rockchip-ep: Remove wrong mask on subsys_vendor_id
Remove wrong mask on subsys_vendor_id. Both the Vendor ID and Subsystem
Vendor ID are u16 variables and are written to a u32 register of the
controller. The Subsystem Vendor ID was always 0 because the u16 value
was masked incorrectly with GENMASK(31,16) resulting in all lower 16
bits being set to 0 prior to the shift.
Remove both masks as they are unnecessary and set the register correctly
i.e., the lower 16-bits are the Vendor ID and the upper 16-bits are the
Subsystem Vendor ID.
This is documented in the RK3399 TRM section 17.6.7.1.17

Modules changes for v6.10-rc1
Finally something fun. Mike Rapoport does some cleanup to allow us to
take out module_alloc() out of modules into a new paint shedded execmem_alloc()
and execmem_free() so to make emphasis these helpers are actually used outside
of modules. It starts with a no-functional changes API rename / placeholders
to then allow architectures to define their requirements into a new shiny
struct execmem_info with ranges, and requirements for those ranges. Archs
now can intitialize this execmem_info as the last part of mm_core_init() if
they have to diverge from the norm. Each range is a known type clearly
articulated and spelled out in enum execmem_type.
Although a lot of this is major cleanup and prep work for future enhancements an
immediate clear gain is we get to enable KPROBES without MODULES now. That is
ultimately what motiviated to pick this work up again, now with smaller goal as
concrete stepping stone.
This has been sitting on linux-next for a little less than a month, a few issues
were found already and fixed, in particular an odd mips boot issue. Arch folks
reviewed the code too. This is ready for wider exposure and testing.

ARM: 9398/1: Fix userspace enter on LPAE with CC_OPTIMIZE_FOR_SIZE=y
Booting an LPAE-enabled kernel built with CONFIG_CC_OPTIMIZE_FOR_SIZE=y
fails when starting userspace:
Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000004
CPU: 1 PID: 1 Comm: init Tainted: G W N 6.9.0-rc1-koelsch-00004-g7af5b901e847 #1930
Hardware name: Generic R-Car Gen2 (Flattened Device Tree)
Call trace:
unwind_backtrace from show_stack+0x10/0x14
show_stack from dump_stack_lvl+0x78/0xa8
dump_stack_lvl from panic+0x118/0x398

do_exit from sys_exit_group+0x0/0x10
---[ end Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000004 ]---
Add the missing memory clobber to cpu_set_ttbcr(), as suggested by
Russell King.
Force inlining of uaccess_save_and_enable(), as suggested by Ard
Biesheuvel.
The latter fixes booting on Koelsch.

kconfig: use sym_get_choice_menu() in sym_check_prop()
Choices and their members are associated via the P_CHOICE property. Currently, prop_get_symbol(sym_get_choice_prop()) is used to obtain the choice of the given choice member. Replace it with sym_get_choice_menu(), which retrieves the choice without relying on P_CHOICE. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> |

sound updates for 6.10-rc1
This one became bigger than usual, not in the total size but rather
containing lots of small changes all over the places. The majority of
changes are about ASoC, especially SOF / Intel stuff, and we see an
interesting work for ASoC DAPM graph visualization, while there are
many other code cleanup and refactoring, too.
Core:
- A deadlock fix at device disconnection
- A new tool dapm-graph for visualising the DAPM state
ASoC:
- Large updates throughout the Intel audio drivers
- Fixes and clarifications for the DAPM documentation
- Cleanups of accessors for driver data, module labelling, and for
constification
- Modernsation and cleanup work in the Mediatek drivers
- Several fixes and features for the DaVinci I2S driver
- New drivers for several AMD and Intel platforms, Nuvoton NAU8325,
Rockchip RK3308 and Texas Instruments PCM6240
HD-audio:
- Cleanup for CONFIG_PM dependencies
- Cirrus HD-audio codec fixes and quirks
Others:
- Series of tree-wide fixes in Makefiles to use *-y
- Additions of missing module descriptions
- Scarlett2 USB mixer enhancements
- A series of legacy emu10k1 fixes and improvements

bpf: save extended inner map info for percpu array maps as well
ARRAY_OF_MAPS and HASH_OF_MAPS map types have special logic to save

they are used as inner maps. PERCPU_ARRAY maps have similar
requirements as they now support generating inline element lookup
logic. So make sure that both classes of maps are handled correctly.

bpf, docs: Fix the description of 'src' in ALU instructions
An ALU instruction's source operand can be the value in the source register or the 32-bit immediate value encoded in the instruction. This is controlled by the 's' bit of the 'opcode'.

Change the description to use 'source operand' in place of 'value of the source register'.

libbpf: fix feature detectors when using token_fd
Adjust `union bpf_attr` size passed to kernel in two feature-detecting
functions to take into account prog_token_fd field.
Libbpf is avoiding memset()'ing entire `union bpf_attr` by only using
minimal set of bpf_attr's fields. Two places have been missed when
wiring BPF token support in libbpf's feature detection logic.
Fix them trivially.

misc: ntsync: mark driver as "broken" to prevent from building
The ntsync code is only partially enabled in the kernel at this point in time, creating the device node and that's about it. Don't confuse systems that expect to see a working ntsync interface by teasing it with this basic structure at this point in time, so mark the code as "broken" so that it is not built and enabled just yet. Once the rest of the code is accepted, this will be reverted so that the driver can be correctly built and used, but for now, this is the safest way forward.

dtschema package with core schemas deprecated pci-bus.yaml schema in favor of pci-host-bridge.yaml. Update all bindings to use the latter one. The difference between pci-bus.yaml and pci-host-bridge.yaml is only in lack of "reg" property defined by the latter, which should not have any effect here, because all these bindings define the "reg".

rtla/timerlat: Add a summary for top mode
While the per-cpu values are the results to take into consideration, the
overall system values are also useful.
Add a summary at the bottom of rtla timerlat top showing the overall
results. For instance:
Timer Latency
0 00:00:10 | IRQ Timer Latency (us) | Thread Timer Latency (us)
CPU COUNT | cur min avg max | cur min avg max
0 #10003 | 113 19 150 441 | 134 35 170 459

rtla/timerlat: Use pretty formatting only on interactive tty
timerlat top does some background/font color formatting. While useful
on terminal, it breaks the output on other formats. For example, when
piping the output for pastebin tools, the format strings are printed
as characters. For instance:
[2;37;40m Timer Latency [0;0;0m
0 00:00:01 | IRQ Timer Latency (us) | Thread Timer Latency (us)
[2;30;47mCPU COUNT | cur min avg max | cur min avg max[0;0;0m
0 #1013 | 1 0 1 54 | 5 2 4 57
1 #1013 | 3 0 1 10 | 6 2 4 15
To avoid this problem, do the formatting only if running on a tty,
and in !quiet mode.

rtla/auto-analysis: Replace \t with spaces
When copying timerlat auto-analysis from a terminal to some web pages or
chats, the \t are being replaced with a single ' ' or ' ', breaking
the output.
For example:
## CPU 3 hit stop tracing, analyzing it ##
IRQ handler delay: 1.30 us (0.11 %)
IRQ latency: 1.90 us
Timerlat IRQ duration: 3.00 us (0.24 %)
Blocking thread: 1223.16 us (99.00 %)
insync:4048 1223.16 us
IRQ interference 4.93 us (0.40 %)
local_timer:236 4.93 us
------------------------------------------------------------------------
Thread latency: 1235.47 us (100%)
Replace \t with spaces to avoid this problem.

rtla/timerlat: Simplify "no value" printing on top
Instead of printing three times the same output, print it only once,
reducing lines and being sure that all no values have the same length.
It also fixes an extra '\n' when running the with kernel threads, like
here:
=============== %< ==============
Timer Latency
0 00:00:01 | IRQ Timer Latency (us) | Thread Timer Latency (us)
CPU COUNT | cur min avg max | cur min avg max
2 #0 | - - - - | 161 161 161 161
3 #0 | - - - - | 161 161 161 161
8 #1 | 54 54 54 54 | - - - -'\n'
---------------|----------------------------------------|---------------------------------------
ALL #1 e0 | 54 54 54 | 161 161 161
=============== %< ==============
This '\n' should have been removed with the user-space support that
added another '\n' if not running with kernel threads.

net: ks8851: Fix another TX stall caused by wrong ISR flag handling
Under some circumstances it may happen that the ks8851 Ethernet driver stops sending data. Currently the interrupt handler resets the interrupt status flags in the hardware after handling TX. With this approach we may lose interrupts in the time window between handling the TX interrupt and resetting the TX interrupt status bit. When all of the three following conditions are true then transmitting data stops: - TX queue is stopped to wait for room in the hardware TX buffer - no queued SKBs in the driver (txq) that wait for being written to hw - hardware TX buffer is empty and the last TX interrupt was lost This is because reenabling the TX queue happens when handling the TX interrupt status but if the TX status bit has already been cleared then this interrupt will never come. With this commit the interrupt status flags will be cleared before they are handled. That way we stop losing interrupts. The wrong handling of the ISR flags was there from the beginning but with commit |

net: bridge: mst: fix vlan use-after-free
syzbot reported a suspicious rcu usage[1] in bridge's mst code. While
fixing it I noticed that nothing prevents a vlan to be freed while
walking the list from the same path (br forward delay timer). Fix the rcu
usage and also make sure we are not accessing freed memory by making
br_mst_vlan_set_state use rcu read lock.

selftests: net: bridge: increase IGMP/MLD exclude timeout membership interval
When running the bridge IGMP/MLD selftests on debug kernels we can get
spurious errors when setting up the IGMP/MLD exclude timeout tests
because the membership interval is just 3 seconds and the setup has 2
seconds of sleep plus various validations, the one second that is left
is not enough. Increase the membership interval from 3 to 5 seconds to
make room for the setup validation and 2 seconds of sleep.
