      LoongArch: Fix wrong fpu version · ad82eef3
      Tiezhu Yang authored
      According to the configuration information accessible by the CPUCFG
      instruction in LoongArch Reference Manual [1], FP_ver is stored in
      bit [5: 3] of CPUCFG2, the current code to get fpu version is wrong,
      use CPUCFG2_FPVERS to fix it.

      LoongArch: Fix EENTRY/MERRENTRY setting in setup_tlb_handler() · 26808ceb
      Huacai Chen authored
      setup_tlb_handler() is expected to set per-cpu exception handlers, but
      it only set the TLBRENTRY successfully because of copy & paste errors,
      so fix it.

      LoongArch: Fix sleeping in atomic context in setup_tlb_handler() · bab1c299
      Huacai Chen authored
      Since setup_tlb_handler() is executed in atomic context, we should use
      GFP_ATOMIC instead of GFP_KERNEL to alloc pages. Otherwise we will get
      a "sleeping in atomic context" error:

      x86/tdx: Handle load_unaligned_zeropad() page-cross to a shared page · 1e776965
      Kirill A. Shutemov authored
      load_unaligned_zeropad() can lead to unwanted loads across page boundaries.
      The unwanted loads are typically harmless. But, they might be made to
      totally unrelated or even unmapped memory. load_unaligned_zeropad()
      relies on exception fixup (#PF, #GP and now #VE) to recover from these
      unwanted loads.
      
      In TDX guests, the second page can be shared page and a VMM may configure
      it to trigger #VE.
      
      The kernel assumes that #VE on a shared page is an MMIO access and tries to
      decode instruction to handle it. In case of load_unaligned_zeropad() it
      may result in confusion as it is not MMIO access.
      
      Fix it by detecting split page MMIO accesses and failing them.
      load_unaligned_zeropad() will recover using exception fixups.
      
      The issue was discovered by analysis and reproduced artificially. It was
      not triggered during testing.

      x86/PCI: Revert "x86/PCI: Clip only host bridge windows for E820 regions" · a2b36ffb
      Hans de Goede authored
      This reverts commit 4c5e242d.
      
      Prior to 4c5e242d ("x86/PCI: Clip only host bridge windows for E820
      regions"), E820 regions did not affect PCI host bridge windows.  We only
      looked at E820 regions and avoided them when allocating new MMIO space.
      If firmware PCI bridge window and BAR assignments used E820 regions, we
      left them alone.
      
      After 4c5e242d, we removed E820 regions from the PCI host bridge
      windows before looking at BARs, so firmware assignments in E820 regions
      looked like errors, and we moved things around to fit in the space left
      (if any) after removing the E820 regions.  This unnecessary BAR
      reassignment broke several machines.
      
      Guilherme reported that Steam Deck fails to boot after 4c5e242d.  We
      clipped the window that contained most 32-bit BARs:
      
        BIOS-e820: [mem 0x00000000a0000000-0x00000000a00fffff] reserved
        acpi PNP0A08:00: clipped [mem 0x80000000-0xf7ffffff window] to [mem 0xa0100000-0xf7ffffff window] for e820 entry [mem 0xa0000000-0xa00fffff]
      
      which forced us to reassign all those BARs, for example, this NVMe BAR:
      
        pci 0000:00:01.2: PCI bridge to [bus 01]
        pci 0000:00:01.2:   bridge window [mem 0x80600000-0x806fffff]
        pci 0000:01:00.0: BAR 0: [mem 0x80600000-0x80603fff 64bit]
        pci 0000:00:01.2: can't claim window [mem 0x80600000-0x806fffff]: no compatible bridge window
        pci 0000:01:00.0: can't claim BAR 0 [mem 0x80600000-0x80603fff 64bit]: no compatible bridge window
      
        pci 0000:00:01.2: bridge window: assigned [mem 0xa0100000-0xa01fffff]
        pci 0000:01:00.0: BAR 0: assigned [mem 0xa0100000-0xa0103fff 64bit]
      
      All the reassignments were successful, so the devices should have been
      functional at the new addresses, but some were not.
      
      Andy reported a similar failure on an Intel MID platform.  Benjamin
      reported a similar failure on a VMWare Fusion VM.
      
      Note: this is not a clean revert; this revert keeps the later change to
      make the clipping dependent on a new pci_use_e820 bool, moving the checking
      of this bool to arch_remove_reservations().

      arm64: mm: Don't invalidate FROM_DEVICE buffers at start of DMA transfer · c50f11c6
      Will Deacon authored
      Invalidating the buffer memory in arch_sync_dma_for_device() for
      FROM_DEVICE transfers
      
      When using the streaming DMA API to map a buffer prior to inbound
      non-coherent DMA (i.e. DMA_FROM_DEVICE), we invalidate any dirty CPU
      cachelines so that they will not be written back during the transfer and
      corrupt the buffer contents written by the DMA. This, however, poses two
      potential problems:
      
        (1) If the DMA transfer does not write to every byte in the buffer,
            then the unwritten bytes will contain stale data once the transfer
            has completed.
      
        (2) If the buffer has a virtual alias in userspace, then stale data
            may be visible via this alias during the period between performing
            the cache invalidation and the DMA writes landing in memory.
      
      Address both of these issues by cleaning (aka writing-back) the dirty
      lines in arch_sync_dma_for_device(DMA_FROM_DEVICE) instead of discarding
      them using invalidation.
