The acpi4asus project appears to be defunct, according to:
https://sourceforge.net/p/acpi4asus/mailman/acpi4asus-user/
the last posts to the list were done in May 2020 and even then
they were mostly spam.

And the http://acpi4asus.sf.net website still talks about 2.6.x kernels.

Linus Torvalds 9d64bf433c perf tools improvements and fixes for v6.8:
- Add Namhyung Kim as tools/perf/ co-maintainer, we're taking turns processing
   patches, switching roles from perf-tools to perf-tools-next at each Linux
   release.
 
 Data profiling:
 
 - Associate samples that identify loads and stores with data structures. This
   uses events available on Intel, AMD and others and DWARF info:
 
     # To get memory access samples in kernel for 1 second (on Intel)
     $ perf mem record -a -K --ldlat=4 -- sleep 1
 
     # Similar for the AMD (but it requires 6.3+ kernel for BPF filters)
     $ perf mem record -a --filter 'mem_op == load || mem_op == store, ip > 0x8000000000000000' -- sleep 1
 
   Then, amongst several modes of post processing, one can do things like:
 
     $ perf report -s type,typeoff --hierarchy --group --stdio
     ...
     #
     # Samples: 10K of events 'cpu/mem-loads,ldlat=4/P, cpu/mem-stores/P, dummy:u'

   This uses the existing annotate code, calling objdump to do the disassembly,
   with improvements to avoid having this take too long, but longer term a
   switch to a disassembler library, possibly reusing code in the kernel will
   be pursued.
 
   This is the initial implementation, please use it and report impressions and
   bugs. Make sure the kernel-debuginfo packages match the running kernel. The
   'perf report' phase for non short perf.data files may take a while.
 
   There is a great article about it on LWN:

   kernel, while doing a simple 'find /' on an otherwise idle system resulted in:

 perf top/report:
 
 - Don't ignore job control, allowing control+Z + bg to work.
 
 - Add s390 raw data interpretation for PAI (Processor Activity Instrumentation)
   counters.
 
 perf archive:
 
 - Add new option '--all' to pack perf.data with DSOs.
 
 - Add new option '--unpack' to expand tarballs.
 
 Initialization speedups:
 
 - Lazily initialize zstd streams to save memory when not using it.
 
 - Lazily allocate/size mmap event copy.
 
 - Lazy load kernel symbols in 'perf record'.
 
 - Be lazier in allocating lost samples buffer in 'perf record'.
 
 - Don't synthesize BPF events when disabled via the command line (perf record --no-bpf-event).
 
 Assorted improvements:
 
 - Show note on AMD systems that the :p, :pp, :ppp and :P are all the same, as
   IBS (Instruction Based Sampling) is used and it is inherentely precise, not
   having levels of precision like in Intel systems.
 
 - When 'cycles' isn't available, fall back to the "task-clock" event when not
   system wide, not to 'cpu-clock'.
 
 - Add --debug-file option to redirect debug output, e.g.:
 
     $ perf --debug-file /tmp/perf.log record -v true
 
 - Shrink 'struct map' to under one cacheline by avoiding function pointers for
   selecting if addresses are identity or DSO relative, and using just a byte for
   some boolean struct members.
 
 - Resolve the arch specific strerrno just once to use in perf_env__arch_strerrno().
 
 - Reduce memory for recording PERF_RECORD_LOST_SAMPLES event.
 
 Assorted fixes:
 
 - Fix the default 'perf top' usage on Intel hybrid systems, now it starts with
   a browser showing the number of samples for Efficiency (cpu_atom/cycles/P) and
   Performance (cpu_core/cycles/P). This behaviour is similar on ARM64, with its
   respective set of big.LITTLE processors.
 
 - Fix segfault on build_mem_topology() error path.
 
 - Fix 'perf mem' error on hybrid related to availability of mem event in a PMU.
 
 - Fix missing reference count gets (map, maps) in the db-export code.
 
 - Avoid recursively taking env->bpf_progs.lock in the 'perf_env' code.
 
 - Use the newly introduced maps__for_each_map() to add missing locking around
   iteration of 'struct map' entries.
 
 - Parse NOTE segments until the build id is found, don't stop on the first one,
   ELF files may have several such NOTE segments.
 
 - Remove 'egrep' usage, its deprecated, use 'grep -E' instead.
 
 - Warn first about missing libelf, not libbpf, that depends on libelf.
 
 - Use alternative to 'find ... -printf' as this isn't supported in busybox.
 
 - Address python 3.6 DeprecationWarning for string scapes.
 
 - Fix memory leak in uniq() in libsubcmd.
 
 - Fix man page formatting for 'perf lock'
 
 - Fix some spelling mistakes.
 
 perf tests:
 
 - Fail shell tests that needs some symbol in perf itself if it is stripped.
   These tests check if a symbol is resolved, if some hot function is indeed
   detected by profiling, etc.
 
 - The 'perf test sigtrap' test is currently failing on PREEMPT_RT, skip it if
   sleeping spinlocks are detected (using BTF) and point to the mailing list
   discussion about it. This test is also being skipped on several architectures
   (powerpc, s390x, arm and aarch64) due to other pending issues with intruction
   breakpoints.
 
 - Adjust test case perf record offcpu profiling tests for s390.
 
 - Fix 'Setup struct perf_event_attr' fails on s390 on z/VM guest, addressing
   issues caused by the fallback from cycles to task-clock done in this release.
 
 - Fix mask for VG register in the user-regs test.
 
 - Use shellcheck on 'perf test' shell scripts automatically to make sure changes
   don't introduce things it flags as problematic.
 
 - Add option to change objdump binary and allow it to be set via 'perf config'.
 
 - Add basic 'perf script', 'perf list --json" and 'perf diff' tests.
 
 - Basic branch counter support.
 
 - Make DSO tests a suite rather than individual.
 
 - Remove atomics from test_loop to avoid test failures.
 
 - Fix call chain match on powerpc for the record+probe_libc_inet_pton test.
 
 - Improve Intel hybrid tests.
 
 Vendor event files (JSON):
 
 powerpc:
 
 - Update datasource event name to fix duplicate events on IBM's Power10.
 
 - Add PVN for HX-C2000 CPU with Power8 Architecture.
 
 Intel:
 
 - Alderlake/rocketlake metric fixes.
 
 - Update emeraldrapids events to v1.02.
 
 - Update icelakex events to v1.23.
 
 - Update sapphirerapids events to v1.17.
 
 - Add skx, clx, icx and spr upi bandwidth metric.
 
 AMD:
 
 - Add Zen 4 memory controller events.
 
 RISC-V:
 
 - Add StarFive Dubhe-80 and Dubhe-90 JSON files.
   https://www.starfivetech.com/en/site/cpu-u
 
 - Add T-HEAD C9xx JSON file.
   https://github.com/riscv-software-src/opensbi/blob/master/docs/platform/thead-c9xx.md
 
 ARM64:
 
 - Remove UTF-8 characters from cmn.json, that were causing build failure in some
   distros.
 
 - Add core PMU events and metrics for Ampere One X.
 
 - Rename Ampere One's BPU_FLUSH_MEM_FAULT to GPC_FLUSH_MEM_FAULT
 
 libperf:
 
 - Rename several perf_cpu_map constructor names to clarify what they really do.
 
 - Ditto for some other methods, coping with some issues in their semantics,
   like perf_cpu_map__empty() -> perf_cpu_map__has_any_cpu_or_is_empty().
 
 - Document perf_cpu_map__nr()'s behavior
 
 perf stat:
 
 - Exit if parse groups fails.
 
 - Combine the -A/--no-aggr and --no-merge options.
 
 - Fix help message for --metric-no-threshold option.
 
 Hardware tracing:
 
 ARM64 CoreSight:
 
 - Bump minimum OpenCSD version to ensure a bugfix is present.
 
 - Add 'T' itrace option for timestamp trace
 
 - Set start vm addr of exectable file to 0 and don't ignore first sample on the
   arm-cs-trace-disasm.py 'perf script'.

 "Add Namhyung Kim as tools/perf/ co-maintainer, we're taking turns
  processing patches, switching roles from perf-tools to perf-tools-next
  at each Linux release.

  Data profiling:

   - Associate samples that identify loads and stores with data
     structures. This uses events available on Intel, AMD and others and
     DWARF info:

       # To get memory access samples in kernel for 1 second (on Intel)
       $ perf mem record -a -K --ldlat=4 -- sleep 1

       # Similar for the AMD (but it requires 6.3+ kernel for BPF filters)
       $ perf mem record -a --filter 'mem_op == load || mem_op == store, ip > 0x8000000000000000' -- sleep 1

     Then, amongst several modes of post processing, one can do things like:

       $ perf report -s type,typeoff --hierarchy --group --stdio
       ...
       #
       # Samples: 10K of events 'cpu/mem-loads,ldlat=4/P, cpu/mem-stores/P, dummy:u'

     This uses the existing annotate code, calling objdump to do the
     disassembly, with improvements to avoid having this take too long,
     but longer term a switch to a disassembler library, possibly
     reusing code in the kernel will be pursued.

     This is the initial implementation, please use it and report
     impressions and bugs. Make sure the kernel-debuginfo packages match
     the running kernel. The 'perf report' phase for non short perf.data
     files may take a while.

     There is a great article about it on LWN:

       https://lwn.net/Articles/955709/ - "Data-type profiling for perf"

     One last test I did while writing this text, on a AMD Ryzen 5950X,
     using a distro kernel, while doing a simple 'find /' on an
     otherwise idle system resulted in:

  perf top/report:

   - Don't ignore job control, allowing control+Z + bg to work.

   - Add s390 raw data interpretation for PAI (Processor Activity
     Instrumentation) counters.

  perf archive:

   - Add new option '--all' to pack perf.data with DSOs.

   - Add new option '--unpack' to expand tarballs.

  Initialization speedups:

   - Lazily initialize zstd streams to save memory when not using it.

   - Lazily allocate/size mmap event copy.

   - Lazy load kernel symbols in 'perf record'.

   - Be lazier in allocating lost samples buffer in 'perf record'.

   - Don't synthesize BPF events when disabled via the command line
     (perf record --no-bpf-event).

  Assorted improvements:

   - Show note on AMD systems that the :p, :pp, :ppp and :P are all the
     same, as IBS (Instruction Based Sampling) is used and it is
     inherentely precise, not having levels of precision like in Intel
     systems.

   - When 'cycles' isn't available, fall back to the "task-clock" event
     when not system wide, not to 'cpu-clock'.

   - Add --debug-file option to redirect debug output, e.g.:

       $ perf --debug-file /tmp/perf.log record -v true

   - Shrink 'struct map' to under one cacheline by avoiding function
     pointers for selecting if addresses are identity or DSO relative,
     and using just a byte for some boolean struct members.

   - Resolve the arch specific strerrno just once to use in
     perf_env__arch_strerrno().

   - Reduce memory for recording PERF_RECORD_LOST_SAMPLES event.

  Assorted fixes:

   - Fix the default 'perf top' usage on Intel hybrid systems, now it
     starts with a browser showing the number of samples for Efficiency
     (cpu_atom/cycles/P) and Performance (cpu_core/cycles/P). This
     behaviour is similar on ARM64, with its respective set of
     big.LITTLE processors.

   - Fix segfault on build_mem_topology() error path.

   - Fix 'perf mem' error on hybrid related to availability of mem event
     in a PMU.

   - Fix missing reference count gets (map, maps) in the db-export code.

   - Avoid recursively taking env->bpf_progs.lock in the 'perf_env'
     code.

   - Use the newly introduced maps__for_each_map() to add missing
     locking around iteration of 'struct map' entries.

   - Parse NOTE segments until the build id is found, don't stop on the
     first one, ELF files may have several such NOTE segments.

   - Remove 'egrep' usage, its deprecated, use 'grep -E' instead.

   - Warn first about missing libelf, not libbpf, that depends on
     libelf.

   - Use alternative to 'find ... -printf' as this isn't supported in
     busybox.

   - Address python 3.6 DeprecationWarning for string scapes.

   - Fix memory leak in uniq() in libsubcmd.

   - Fix man page formatting for 'perf lock'

   - Fix some spelling mistakes.

  perf tests:

   - Fail shell tests that needs some symbol in perf itself if it is
     stripped. These tests check if a symbol is resolved, if some hot
     function is indeed detected by profiling, etc.

   - The 'perf test sigtrap' test is currently failing on PREEMPT_RT,
     skip it if sleeping spinlocks are detected (using BTF) and point to
     the mailing list discussion about it. This test is also being
     skipped on several architectures (powerpc, s390x, arm and aarch64)
     due to other pending issues with intruction breakpoints.

   - Adjust test case perf record offcpu profiling tests for s390.

   - Fix 'Setup struct perf_event_attr' fails on s390 on z/VM guest,
     addressing issues caused by the fallback from cycles to task-clock
     done in this release.

   - Fix mask for VG register in the user-regs test.

   - Use shellcheck on 'perf test' shell scripts automatically to make
     sure changes don't introduce things it flags as problematic.

   - Add option to change objdump binary and allow it to be set via
     'perf config'.

   - Add basic 'perf script', 'perf list --json" and 'perf diff' tests.

   - Basic branch counter support.

   - Make DSO tests a suite rather than individual.

   - Remove atomics from test_loop to avoid test failures.

   - Fix call chain match on powerpc for the record+probe_libc_inet_pton
     test.

   - Improve Intel hybrid tests.

  Vendor event files (JSON):

  powerpc:

   - Update datasource event name to fix duplicate events on IBM's
     Power10.

   - Add PVN for HX-C2000 CPU with Power8 Architecture.

  Intel:

   - Alderlake/rocketlake metric fixes.

   - Update emeraldrapids events to v1.02.

   - Update icelakex events to v1.23.

   - Update sapphirerapids events to v1.17.

   - Add skx, clx, icx and spr upi bandwidth metric.

  AMD:

   - Add Zen 4 memory controller events.

  RISC-V:

   - Add StarFive Dubhe-80 and Dubhe-90 JSON files.
       https://www.starfivetech.com/en/site/cpu-u

   - Add T-HEAD C9xx JSON file.
       https://github.com/riscv-software-src/opensbi/blob/master/docs/platform/thead-c9xx.md

  ARM64:

   - Remove UTF-8 characters from cmn.json, that were causing build
     failure in some distros.

   - Add core PMU events and metrics for Ampere One X.

   - Rename Ampere One's BPU_FLUSH_MEM_FAULT to GPC_FLUSH_MEM_FAULT

  libperf:

   - Rename several perf_cpu_map constructor names to clarify what they
     really do.

   - Ditto for some other methods, coping with some issues in their
     semantics, like perf_cpu_map__empty() ->
     perf_cpu_map__has_any_cpu_or_is_empty().

   - Document perf_cpu_map__nr()'s behavior

  perf stat:

   - Exit if parse groups fails.

   - Combine the -A/--no-aggr and --no-merge options.

   - Fix help message for --metric-no-threshold option.

  Hardware tracing:

  ARM64 CoreSight:

   - Bump minimum OpenCSD version to ensure a bugfix is present.

   - Add 'T' itrace option for timestamp trace

   - Set start vm addr of exectable file to 0 and don't ignore first
     sample on the arm-cs-trace-disasm.py 'perf script'"

Merge tag 'vfs-6.8.netfs' of gitolite.kernel.org:pub/scm/linux/kernel/git/vfs/vfs

Pull netfs updates from Christian Brauner:
 "This extends the netfs helper library that network filesystems can use
  to replace their own implementations. Both afs and 9p are ported. cifs
  is ready as well but the patches are way bigger and will be routed
  separately once this is merged. That will remove lots of code as well.

  The overal goal is to get high-level I/O and knowledge of the page
  cache and ouf of the filesystem drivers. This includes knowledge about
  the existence of pages and folios

  The pull request converts afs and 9p. This removes about 800 lines of
  code from afs and 300 from 9p. For 9p it is now possible to do writes
  in larger than a page chunks. Additionally, multipage folio support
  can be turned on for 9p. Separate patches exist for cifs removing
  another 2000+ lines. I've included detailed information in the
  individual pulls I took.

  Summary:

   - Add NFS-style (and Ceph-style) locking around DIO vs buffered I/O
     calls to prevent these from happening at the same time.

   - Support for direct and unbuffered I/O.

   - Support for write-through caching in the page cache.

   - O_*SYNC and RWF_*SYNC writes use write-through rather than writing
     to the page cache and then flushing afterwards.

   - Support for write-streaming.

   - Support for write grouping.

   - Skip reads for which the server could only return zeros or EOF.

   - The fscache module is now part of the netfs library and the
     corresponding maintainer entry is updated.

   - Some helpers from the fscache subsystem are renamed to mark them as
     belonging to the netfs library.

   - Follow-up fixes for the netfs library.

   - Follow-up fixes for the 9p conversion"

Linus Torvalds ed8d84530a This cycle, I2C removes the currently unused CLASS_DDC support
(controllers set the flag, but there is no client to use it). Also,
 CLASS_SPD support gets simplified to prepare removal in the future.
 Class based instantiation is not recommended these days anyhow.
 Furthermore, I2C core now creates a debugfs directory per I2C adapter.
 Current bus driver users were converted to use it. Then, there are also
 quite some driver updates. Standing out are patches for the wmt-driver
 which is refactored to support more variants. This is the rebased pull
 request where a large series for the designware driver was dropped.

Merge tag 'cxl-for-6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl

Pull CXL (Compute Express Link) updates from Dan Williams:
 "The bulk of this update is support for enumerating the performance
  capabilities of CXL memory targets and connecting that to a platform
  CXL memory QoS class. Some follow-on work remains to hook up this data
  into core-mm policy, but that is saved for v6.9.

  The next significant update is unifying how CXL event records (things
  like background scrub errors) are processed between so called
  "firmware first" and native error record retrieval. The CXL driver
  handler that processes the record retrieved from the device mailbox is
  now the handler for that same record format coming from an EFI/ACPI
  notification source.

  This also contains miscellaneous feature updates, like Get Timestamp,
  and other fixups.

  Summary:

   - Add support for parsing the Coherent Device Attribute Table (CDAT)

   - Add support for calculating a platform CXL QoS class from CDAT data

   - Unify the tracing of EFI CXL Events with native CXL Events.

- Add debugfs support, initially used for reporting device migration
    state. (Longfang Liu)
 
  - Fixes and support for migration dirty tracking across multiple IOVA
    regions in the pds-vfio-pci driver. (Brett Creeley)
 
  - Improved IOMMU allocation accounting visibility. (Pasha Tatashin)
 
  - Virtio infrastructure and a new virtio-vfio-pci variant driver, which
    provides emulation of a legacy virtio interfaces on modern virtio
    hardware for virtio-net VF devices where the PF driver exposes
    support for legacy admin queues, ie. an emulated IO BAR on an SR-IOV
    VF to provide driver ABI compatibility to legacy devices.
    (Yishai Hadas & Feng Liu)
 
  - Migration fixes for the hisi-acc-vfio-pci variant driver.
    (Shameer Kolothum)
 
  - Kconfig dependency fix for new virtio-vfio-pci variant driver.
    (Arnd Bergmann)

Linus Torvalds 302d185865 s390 updates for 6.8 merge window part 2
- do not enable by default the support of 31-bit Enterprise Systems
   Architecture (ESA) ELF binaries
 
 - drop automatic CONFIG_KEXEC selection, while set CONFIG_KEXEC=y
   explicitly for defconfig and debug_defconfig only
 
 - fix zpci_get_max_io_size() to allow PCI block stores where
   normal PCI stores were used otherwise
 
 - remove unneeded tsk variable in do_exception() fault handler
 
 - __load_fpu_regs() is only called from the core kernel code.
   Therefore, remove not needed EXPORT_SYMBOL.
 
 - remove leftover comment from s390_fpregs_set() callback
 
 - few cleanups to Processor Activity Instrumentation (PAI) code
   (which perf framework is based on)
 
 - replace Wenjia Zhang with Thorsten Winkler as s390 Inter-User
   Communication Vehicle (IUCV) networking maintainer
 
 - Fix all scenarios where queues previously removed from a guest's
   Adjunct-Processor (AP) configuration do not re-appear in a reset
   state when they are subsequently made available to a guest again

Linus Torvalds bd736f38c0 TTY/Serial changes for 6.8-rc1
Here is the big set of tty and serial driver changes for 6.8-rc1.
 
 As usual, Jiri has a bunch of refactoring and cleanups for the tty core
 and drivers in here, along with the usual set of rs485 updates (someday
 this might work properly...)  Along with those, in here are changes for:
   - sc16is7xx serial driver updates
   - platform driver removal api updates
   - amba-pl011 driver updates
   - tty driver binding updates
   - other small tty/serial driver updates and changes
 
 All of these have been in linux-next for a while with no reported
 issues.
