2024-10-25s390/kdump: Provide is_kdump_kernel() implementationDavid Hildenbrand
s390 sets "elfcorehdr_addr = ELFCORE_ADDR_MAX;" early during setup_arch() to deactivate the "elfcorehdr= kernel" parameter, resulting in is_kdump_kernel() returning "false". During vmcore_init()->elfcorehdr_alloc(), if on a dump kernel and allocation succeeded, elfcorehdr_addr will be set to a valid address and is_kdump_kernel() will consequently return "true". is_kdump_kernel() should return a consistent result during all boot stages, and properly return "true" if in a kdump environment - just like it is done on powerpc where "false" is indicated in fadump environments, as added in commit b098f1c32365 ("powerpc/fadump: make is_kdump_kernel() return false when fadump is active"). Similarly provide a custom is_kdump_kernel() implementation that will only return "true" in kdump environments, and will do so consistently during boot. Update the documentation of dump_available().

kernel_page_present() was intentionally not implemented when adding ARCH_HAS_SET_DIRECT_MAP support, since it was only used for suspend/resume which is not supported anymore on s390.

2024-10-25s390/cio: Do not unregister the subchannel based on DNVVineeth Vijayan
Starting with commit 2297791c92d0 ("s390/cio: dont unregister subchannel from child-drivers"), CIO does not unregister subchannels when the attached device is invalid or unavailable. Instead, it allows subchannels to exist without a connected device. However, if the DNV value is 0, such as, when all the CHPIDs of a subchannel are configured in standby state, the subchannel is unregistered, which contradicts the current subchannel specification. Update the logic so that subchannels are not unregistered based on the DNV value. Also update the SCHIB information even if the DNV bit is zero.

2024-10-10s390/virtio_ccw: Fix dma_parm pointer not set upHalil Pasic
At least since commit 334304ac2bac ("dma-mapping: don't return errors from dma_set_max_seg_size") setting up device.dma_parms is basically mandated by the DMA API. As of now Channel (CCW) I/O in general does not utilize the DMA API, except for virtio. For virtio-ccw however the common virtio DMA infrastructure is such that most of the DMA stuff hinges on the virtio parent device, which is a CCW device. So lets set up the dma_parms pointer for the CCW parent device and hope for the best!

2024-10-10s390/pci: Ignore RID for isolated VFsNiklas Schnelle
Ensure that VFs used in isolation, that is with their parent PF not visible to the configuration but with their RID exposed, are treated compatibly with existing isolated VF use cases without exposed RID including RoCE Express VFs. This allows creating configurations where one LPAR manages PFs while their child VFs are used by other LPARs. This gives the LPAR managing the PFs a role analogous to that of the hypervisor in a typical use case of passing child VFs to guests. Instead of creating a multifunction struct zpci_bus whenever a PCI function with RID exposed is discovered only create such a bus for configured physical functions and only consider multifunction busses when searching for an existing bus. Additionally only set zdev->devfn to the devfn part of the RID once the function is added to a multifunction bus. This also fixes probing of more than 7 such isolated VFs from the same physical bus. This is because common PCI code in pci_scan_slot() only looks for more functions when pdev->multifunction is set which somewhat counter intutively is not the case for VFs. Note that PFs are looked at before their child VFs is guaranteed because we sort the zpci_list by RID ascending.

2024-10-10s390/pci: Use topology ID for multi-function devicesNiklas Schnelle
The newly introduced topology ID (TID) field in the CLP Query PCI Function explicitly identifies groups of PCI functions whose RIDs belong to the same (sub-)topology. When available use the TID instead of the PCHID to match zPCI busses/domains for multi-function devices. Note that currently only a single PCI bus per TID is supported. This change is required because in future machines the PCHID will not identify a PCI card but a specific port in the case of some multi-port NICs while from a PCI point of view the entire card is a subtopology.

2024-10-10s390/pci: Sort PCI functions prior to creating virtual bussesNiklas Schnelle
Instead of relying on the observed but not architected firmware behavior that PCI functions from the same card are listed in ascending RID order in clp_list_pci() ensure this by sorting. To allow for sorting separate the initial clp_list_pci() and creation of the virtual PCI busses. Note that fundamentally in our per-PCI function hotplug design non RID order of discovery is still possible. For example when the two PFs of a two port NIC are hotplugged after initial boot and in descending RID order. In this case the virtual PCI bus would be created by the second PF using that PF's UID as domain number instead of that of the first PF. Thus the domain number would then change from the UID of the second PF to that of the first PF on reboot but there is really nothing we can do about that since changing domain numbers at runtime seems even worse. This only impacts the domain number as the RIDs are consistent and thus even with just the second PF visible it will show up in the correct position on the virtual bus.

2024-10-06platform/x86:intel/pmc: Disable ACPI PM Timer disabling on Sky and Kaby LakeHans de Goede
There have been multiple reports that the ACPI PM Timer disabling is causing Sky and Kaby Lake systems to hang on all suspend (s2idle, s3, hibernate) methods. Remove the acpi_pm_tmr_ctl_offset and acpi_pm_tmr_disable_bit settings from spt_reg_map to disable the ACPI PM Timer disabling on Sky and Kaby Lake to fix the hang on suspend.

2024-10-06platform/x86: dell-laptop: Do not fail when encountering unsupported batteriesArmin Wolf
If the battery hook encounters a unsupported battery, it will return an error. This in turn will cause the battery driver to automatically unregister the battery hook. On machines with multiple batteries however, this will prevent the battery hook from handling the primary battery, since it will always get unregistered upon encountering one of the unsupported batteries. Fix this by simply ignoring unsupported batteries.

git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD KVM/arm64 fixes for 6.12, take #1 - Fix pKVM error path on init, making sure we do not change critical system registers as we're about to fail - Make sure that the host's vector length is at capped by a value common to all CPUs - Fix kvm_has_feat*() handling of "negative" features, as the current code is pretty broken - Promote Joey to the status of official reviewer, while James steps down -- hopefully only temporarly
2024-10-06x86/reboot: emergency callbacks are now registered by common KVM codePaolo Bonzini
Guard them with CONFIG_KVM_X86_COMMON rather than the two vendor modules. In practice this has no functional change, because CONFIG_KVM_X86_COMMON is set if and only if at least one vendor-specific module is being built. However, it is cleaner to specify CONFIG_KVM_X86_COMMON for functions that are used in kvm.ko. Reported-by: Linus Torvalds <torvalds@linux-foundation.org> Fixes: 590b09b1d88e ("KVM: x86: Register "emergency disable" callbacks when virt is enabled") Fixes: 6d55a94222db ("x86/reboot: Unconditionally define cpu_emergency_virt_cb typedef") Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2024-10-06KVM: x86: leave kvm.ko out of the build if no vendor module is requestedPaolo Bonzini
kvm.ko is nothing but library code shared by kvm-intel.ko and kvm-amd.ko. It provides no functionality on its own and it is unnecessary unless one of the vendor-specific module is compiled. In particular, /dev/kvm is not created until one of kvm-intel.ko or kvm-amd.ko is loaded. Use CONFIG_KVM to decide if it is built-in or a module, but use the vendor-specific modules for the actual decision on whether to build it. This also fixes a build failure when CONFIG_KVM_INTEL and CONFIG_KVM_AMD are both disabled. The cpu_emergency_register_virt_callback() function is called from kvm.ko, but it is only defined if at least one of CONFIG_KVM_INTEL and CONFIG_KVM_AMD is provided.
