      x86/kexec: Do not update E820 kexec table for setup_data · fc7f27cd
      Dave Young authored
      crashkernel reservation failed on a Thinkpad t440s laptop recently.
      Actually the memblock reservation succeeded, but later insert_resource()
      failed.
      
      Test steps:
        kexec load -> /* make sure add crashkernel param eg. crashkernel=160M */
          kexec reboot ->
              dmesg|grep "crashkernel reserved";
                  crashkernel memory range like below reserved successfully:
                    0x00000000d0000000 - 0x00000000da000000
              But no such "Crash kernel" region in /proc/iomem
      
      The background story:
      
      Currently the E820 code reserves setup_data regions for both the current
      kernel and the kexec kernel, and it inserts them into the resources list.
      
      Before the kexec kernel reboots nobody passes the old setup_data, and
      kexec only passes fresh SETUP_EFI/SETUP_IMA/SETUP_RNG_SEED if needed.
      Thus the old setup data memory is not used at all.
      
      Due to old kernel updates the kexec e820 table as well so kexec kernel
      sees them as E820_TYPE_RESERVED_KERN regions, and later the old setup_data
      regions are inserted into resources list in the kexec kernel by
      e820__reserve_resources().
      
      Note, due to no setup_data is passed in for those old regions they are not
      early reserved (by function early_reserve_memory), and the crashkernel
      memblock reservation will just treat them as usable memory and it could
      reserve the crashkernel region which overlaps with the old setup_data
      regions. And just like the bug I noticed here, kdump insert_resource
      failed because e820__reserve_resources has added the overlapped chunks
      in /proc/iomem already.
      
      Finally, looking at the code, the old setup_data regions are not used
      at all as no setup_data is passed in by the kexec boot loader. Although
      something like SETUP_PCI etc could be needed, kexec should pass
      the info as new setup_data so that kexec kernel can take care of them.
      This should be taken care of in other separate patches if needed.
      
      Thus drop the useless buggy code here.

      Takashi Iwai authored
      This reverts commit 1601cd53.
      
      This fix is applied globally to all devices, and it may change the
      existing control names.  When the devices are managed with the fixed
      configuration like UCM, such control name mismatch may lead to
      significant regressions.
      
      For avoiding that kind of regression, we would need to apply such
      changes conditionally, but it'd take time to settle down.
      While the original fix is a good thing in general, in order to address
      the regression, let's revert the change for now.

      timer/migration: Remove buggy early return on deactivation · 4b6f4c5a
      Frederic Weisbecker authored
      When a CPU enters into idle and deactivates itself from the timer
      migration hierarchy without any global timer of its own to propagate,
      the group event of that CPU is set to "ignore" and tmigr_update_events()
      accordingly performs an early return without considering timers queued
      by other CPUs.
      
      If the hierarchy has a single level, and the CPU is the last one to
      enter idle, it will ignore others' global timers, as in the following
      layout:
      
                 [GRP0:0]
               migrator = 0
               active   = 0
               nextevt  = T0i
                /         \
               0           1
            active (T0i)  idle (T1)
      
      0) CPU 0 is active thus its event is ignored (the letter 'i') and so are
      upper levels' events. CPU 1 is idle and has the timer T1 enqueued.
      
                 [GRP0:0]
               migrator = NONE
               active   = NONE
               nextevt  = T0i
                /         \
               0           1

      1) CPU 0 goes idle without global event queued. Therefore KTIME_MAX is
      pushed as its next expiry and its own event kept as "ignore". As a result
      tmigr_update_events() ignores T1 and CPU 0 goes to idle with T1
      unhandled.
      
      This isn't proper to single level hierarchy though. A similar issue,
      although slightly different, may arise on multi-level:
      
                                  [GRP1:0]
                               migrator = GRP0:0
                               active   = GRP0:0
                               nextevt  = T0:0i, T0:1
                               /              \
                    [GRP0:0]                  [GRP0:1]
                 migrator = 0              migrator = NONE
                 active   = 0              active   = NONE
                 nextevt  = T0i            nextevt  = T2
                 /         \                /         \
                0 (T0i)     1 (T1)         2 (T2)      3
            active         idle            idle       idle
      
      0) CPU 0 is active thus its event is ignored (the letter 'i') and so are
      upper levels' events. CPU 1 is idle and has the timer T1 enqueued.
      CPU 2 also has a timer. The expiry order is T0 (ignored) < T1 < T2
      
                                  [GRP1:0]
                               migrator = GRP0:0

                               /              \
                    [GRP0:0]                  [GRP0:1]
                 migrator = NONE           migrator = NONE

      1) CPU 0 goes idle without global event queued. Therefore KTIME_MAX is
      pushed as its next expiry and its own event kept as "ignore". As a result
      tmigr_update_events() ignores T1. The change only propagated up to 1st
      level so far.
      
                                  [GRP1:0]
                               migrator = NONE
                               active   = NONE
                               nextevt  = T0:1
                               /              \
                    [GRP0:0]                  [GRP0:1]

              idle         idle            idle         idle
      
      2) The change now propagates up to the top. tmigr_update_events() finds
      that the child event is ignored and thus removes it. The top level next
      event is now T2 which is returned to CPU 0 as its next effective expiry
      to take account for as the global idle migrator. However T1 has been
      ignored along the way, leaving it unhandled.
      
      Fix those issues with removing the buggy related early return. Ignored
      child events must not prevent from evaluating the other events within
      the same group.

      Linus Torvalds authored
      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

        (struct nfs4_ff_layout_ds *)0xffffffffffffffed
      
      This is clear from the stack trace, we call nfs4_ff_layout_prepare_ds()
      which could error out initializing the mirror_ds, and then we go to
      clean it all up and our check is only for if (!mirror->mirror_ds).  This
      is inconsistent with the rest of the users of mirror_ds, which have
      
        if (IS_ERR_OR_NULL(mirror_ds))
      
      to keep from tripping over this exact scenario.  Fix this up in
      ff_layout_cancel_io() to make sure we don't panic when we get an error.
      I also spot checked all the other instances of checking mirror_ds and we
      appear to be doing the correct checks everywhere, only unconditionally
      dereferencing mirror_ds when we know it would be valid.

      Revert "KVM: arm64: Snapshot all non-zero RES0/RES1 sysreg fields for later checking" · 82affc97
      Oliver Upton authored
      This reverts commits 99101dda and
      b80b701d.
      
      Linus reports that the sysreg reserved bit checks in KVM have led to
      build failures, arising from commit fdd867fe ("arm64/sysreg: Add
      register fields for ID_AA64DFR1_EL1") giving meaning to fields that were
      previously RES0.
      
      Of course, this is a genuine issue, since KVM's sysreg emulation depends
      heavily on the definition of reserved fields. But at this point the
      build breakage is far more offensive, and the right course of action is
      to revert and retry later.
      
      All of these build-time assertions were on by default before
      commit 99101dda ("KVM: arm64: Make build-time check of RES0/RES1
      bits optional"), so deliberately revert it all atomically to avoid
      introducing further breakage of bisection.

      Linus Torvalds authored
      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
         vfio-platform (Alex Williamson)

      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"

      Pull MTD updates from Miquel Raynal:
       "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.
      
         - An optional interrupt property is now described in the bindings"

        The Cadence driver now supports system suspend and resume.
      
        The hisi, mpc, sh_mobile, and npcm drivers have undergone some
        cleanups and improvements. Meanwhile, Uwe continues his work on
        converting the "remove" callback to become a void function.
      
        The pca954x mux driver now supports additional configurations, such as
        isolating faulty channels and flushing stuck buses, among others.
