Hi Linus, The following changes since commit 6a8f57ae2eb07ab39a6f0ccad60c760743051026: Linux 6.3-rc7 (2023-04-16 15:23:53 -0700) are available in the Git repository at: ssh://git@xxxxxxxxxxxxxxxxxxx/pub/scm/linux/kernel/git/hyperv/linux.git tags/hyperv-next-signed-20230424 for you to fetch changes up to a494aef23dfc732945cb42e22246a5c31174e4a5: PCI: hv: Replace retarget_msi_interrupt_params with hyperv_pcpu_input_arg (2023-04-21 21:25:23 +0000) Note that I needed to do a merge with tip/x86/sev because some of Michael's patches were merged into that branch first. I've written down the rationale in the merge commit. This PR can conflict with sysctl-next, because both branches modified VMBus code. A correct resolution can be found here: https://lore.kernel.org/linux-next/20230424154742.131094-1-broonie@xxxxxxxxxx/ Although the resolution is empty, it is correct, because Long rebased his patch multiple times on both linux-next and linux-hyperv, the patch ended up containing the same changes as Luis' patch. ---------------------------------------------------------------- hyperv-next for v6.4 - PCI passthrough for Hyper-V confidential VMs (Michael Kelley) - Hyper-V VTL mode support (Saurabh Sengar) - Move panic report initialization code earlier (Long Li) - Various improvements and bug fixes (Dexuan Cui and Michael Kelley) ---------------------------------------------------------------- Borislav Petkov (AMD) (2): crypto: ccp: Get rid of __sev_platform_init_locked()'s local function pointer x86/coco: Export cc_vendor Dexuan Cui (3): clocksource: hyper-v: make sure Invariant-TSC is used if it is available Drivers: hv: vmbus: Remove the per-CPU post_msg_page PCI: hv: Replace retarget_msi_interrupt_params with hyperv_pcpu_input_arg Dionna Glaze (2): virt/coco/sev-guest: Double-buffer messages x86/sev: Change snp_guest_issue_request()'s fw_err argument Long Li (1): Drivers: hv: move panic report code from vmbus to hv early init code Michael Kelley (14): x86/ioremap: Add hypervisor callback for private MMIO mapping in coco VM x86/hyperv: Reorder code to facilitate future work Drivers: hv: Explicitly request decrypted in vmap_pfn() calls x86/mm: Handle decryption/re-encryption of bss_decrypted consistently init: Call mem_encrypt_init() after Hyper-V hypercall init is done x86/hyperv: Change vTOM handling to use standard coco mechanisms swiotlb: Remove bounce buffer remapping for Hyper-V Drivers: hv: vmbus: Remove second mapping of VMBus monitor pages Drivers: hv: vmbus: Remove second way of mapping ring buffers hv_netvsc: Remove second mapping of send and recv buffers Drivers: hv: Don't remap addresses that are above shared_gpa_boundary PCI: hv: Enable PCI pass-thru devices in Confidential VMs x86/hyperv: Add callback filter to cpumask_to_vpset() x86/hyperv: Exclude lazy TLB mode CPUs from enlightened TLB flushes Peter Gonda (1): crypto: ccp - Name -1 return value as SEV_RET_NO_FW_CALL Saurabh Sengar (10): drivers/clocksource/hyper-v: non ACPI support in hyperv clock ACPI: bus: Add stub acpi_sleep_state_supported() in non-ACPI cases Drivers: hv: vmbus: Convert acpi_device to more generic platform_device dt-bindings: bus: Add Hyper-V VMBus Driver: VMBus: Add Devicetree support x86/init: Make get/set_rtc_noop() public x86/hyperv: Add VTL specific structs and hypercalls x86/hyperv: Make hv_get_nmi_reason public Drivers: hv: Kconfig: Add HYPERV_VTL_MODE x86/hyperv: VTL support for Hyper-V Thomas Gleixner (1): Merge branch 'x86/cc' into x86/sev Wei Liu (1): Merge remote-tracking branch 'tip/x86/sev' into hyperv-next .../devicetree/bindings/bus/microsoft,vmbus.yaml | 54 ++++ Documentation/virt/coco/sev-guest.rst | 20 +- MAINTAINERS | 1 + arch/x86/coco/core.c | 53 ++-- arch/x86/hyperv/Makefile | 1 + arch/x86/hyperv/hv_apic.c | 12 +- arch/x86/hyperv/hv_init.c | 18 +- arch/x86/hyperv/hv_vtl.c | 227 +++++++++++++++ arch/x86/hyperv/ivm.c | 148 ++++++---- arch/x86/hyperv/mmu.c | 11 +- arch/x86/include/asm/coco.h | 24 +- arch/x86/include/asm/hyperv-tlfs.h | 78 +++++ arch/x86/include/asm/mem_encrypt.h | 1 + arch/x86/include/asm/mshyperv.h | 31 +- arch/x86/include/asm/sev-common.h | 4 - arch/x86/include/asm/sev.h | 10 +- arch/x86/include/asm/x86_init.h | 6 + arch/x86/kernel/apic/io_apic.c | 10 +- arch/x86/kernel/cpu/mshyperv.c | 28 +- arch/x86/kernel/sev.c | 15 +- arch/x86/kernel/x86_init.c | 6 +- arch/x86/mm/ioremap.c | 5 + arch/x86/mm/mem_encrypt_amd.c | 10 +- arch/x86/mm/pat/set_memory.c | 3 - drivers/clocksource/hyperv_timer.c | 21 +- drivers/crypto/ccp/sev-dev.c | 22 +- drivers/hv/Kconfig | 30 +- drivers/hv/channel_mgmt.c | 2 +- drivers/hv/connection.c | 113 ++------ drivers/hv/hv.c | 79 ++--- drivers/hv/hv_common.c | 242 +++++++++++++++- drivers/hv/hyperv_vmbus.h | 6 - drivers/hv/ring_buffer.c | 62 ++-- drivers/hv/vmbus_drv.c | 322 ++++++--------------- drivers/net/hyperv/hyperv_net.h | 2 - drivers/net/hyperv/netvsc.c | 48 +-- drivers/pci/controller/pci-hyperv.c | 280 +++++++++++------- drivers/virt/coco/sev-guest/sev-guest.c | 99 ++++--- include/asm-generic/hyperv-tlfs.h | 26 ++ include/asm-generic/mshyperv.h | 26 +- include/linux/acpi.h | 5 + include/linux/swiotlb.h | 2 - include/uapi/linux/psp-sev.h | 7 + include/uapi/linux/sev-guest.h | 18 +- init/main.c | 19 +- kernel/dma/swiotlb.c | 45 +-- 46 files changed, 1388 insertions(+), 864 deletions(-) create mode 100644 Documentation/devicetree/bindings/bus/microsoft,vmbus.yaml create mode 100644 arch/x86/hyperv/hv_vtl.c
