Pre-population has been requested several times to mitigate KVM page faults during guest boot or after live migration. It is also required by TDX before filling in the initial guest memory with measured contents. Introduce it as a generic API.

Add a test case to exercise KVM_PRE_FAULT_MEMORY and run the guest to access the pre-populated area. It tests KVM_PRE_FAULT_MEMORY ioctl for KVM_X86_DEFAULT_VM and KVM_X86_SW_PROTECTED_VM.

Wire KVM_PRE_FAULT_MEMORY ioctl to kvm_mmu_do_page_fault() to populate guest memory. It can be called right after KVM_CREATE_VCPU creates a vCPU, since at that point kvm_mmu_create() and kvm_init_mmu() are called and the vCPU is ready to invoke the KVM page fault handler. The helper function kvm_tdp_map_page() takes care of the logic to process RET_PF_* return values and convert them to success or errno.

Move the accounting of the result of kvm_mmu_do_page_fault() to its callers, as only pf_fixed is common to guest page faults and async #PFs, and upcoming support KVM_PRE_FAULT_MEMORY won't bump _any_ stats.

Account stat.pf_taken in kvm_mmu_page_fault(), i.e. the actual page fault handler, instead of conditionally bumping it in kvm_mmu_do_page_fault(). The "real" page fault handler is the only path that should ever increment the number of taken page faults, as all other paths that "do page fault" are by definition not handling faults that occurred in the guest.

Adds documentation of KVM_PRE_FAULT_MEMORY ioctl. [1] It populates guest memory. It doesn't do extra operations on the underlying technology-specific initialization [2]. For example, CoCo-related operations won't be performed. Concretely for TDX, this API won't invoke TDH.MEM.PAGE.ADD() or TDH.MR.EXTEND(). Vendor-specific APIs are required for such operations. The key point is to adapt of vcpu ioctl instead of VM ioctl. First, populating guest memory requires vcpu. If it is VM ioctl, we need to pick one vcpu somehow. Secondly, vcpu ioctl allows each vcpu to invoke this ioctl in parallel. It helps to scale regarding guest memory size, e.g., hundreds of GB.

The flags AS_UNMOVABLE and AS_INACCESSIBLE were both added just for guest_memfd; AS_UNMOVABLE is already in existing versions of Linux, while AS_INACCESSIBLE was acked for inclusion in 6.11. But really, they are the same thing: only guest_memfd uses them, at least for now, and guest_memfd pages are unmovable because they should not be accessed by the CPU. So merge them into one; use the AS_INACCESSIBLE name which is more comprehensive. At the same time, this fixes an embarrassing bug where AS_INACCESSIBLE was used as a bit mask, despite it being just a bit index. The bug was mostly benign, because AS_INACCESSIBLE's bit representation (1010) corresponded to setting AS_UNEVICTABLE (which is already set) and AS_ENOSPC (except no async writes can happen on the guest_memfd). So the AS_INACCESSIBLE flag simply had no effect.

Per-cpu struct kvm_steal_time is added here, its size is 64 bytes and also defined as 64 bytes, so that the whole structure is in one physical page. When a VCPU is online, function pv_enable_steal_time() is called. This function will pass guest physical address of struct kvm_steal_time and tells hypervisor to enable steal time. When a vcpu is offline, physical address is set as 0 and tells hypervisor to disable steal time. Here is an output of vmstat on guest when there is workload on both host and guest. It shows steal time stat information. procs -----------memory---------- -----io---- -system-- ------cpu----- r b swpd free inact active bi bo in cs us sy id wa st 15 1 0 7583616 184112 72208 20 0 162 52 31 6 43 0 20 17 0 0 7583616 184704 72192 0 0 6318 6885 5 60 8 5 22 16 0 0 7583616 185392 72144 0 0 1766 1081 0 49 0 1 50 16 0 0 7583616 184816 72304 0 0 6300 6166 4 62 12 2 20 18 0 0 7583632 184480 72240 0 0 2814 1754 2 58 4 1 35 Signed-off-by: Bibo Mao <maobibo@loongson.cn> Signed-off-by: Huacai Chen <chenhuacai@loongson.cn>

Function kvm_map_page_fast() is fast path of secondary mmu page fault flow, pfn is parsed from secondary mmu page table walker. However the corresponding page reference is not added, it is dangerious to access page out of mmu_lock. Here page ref is added inside mmu_lock, function kvm_set_pfn_accessed() and kvm_set_pfn_dirty() is called with page ref added, so that the page will not be freed by others. Also kvm_set_pfn_accessed() is removed here since it is called in the following function kvm_release_pfn_clean().

When updating pmd entry such as allocating new pmd page or splitting huge page into normal page, it is necessary to firstly update all pte entries, and then update pmd entry. It is weak order with LoongArch system, there will be problem if other VCPUs see pmd update firstly while ptes are not updated. Here smp_wmb() is added to assure this.

Currently page level selection about secondary mmu depends on memory slot and page level about host mmu. There will be problems if page level of secondary mmu is zero already. Huge page cannot be selected if there is normal page mapped in secondary mmu already, since it is not supported to merge normal pages into huge pages now. So page level selection should depend on the following three conditions. 1. Memslot is aligned for huge page and vm is not migrating. 2. Page level of host mmu is also huge page. 3. Page level of secondary mmu is suituable for huge page. Signed-off-by: Bibo Mao <maobibo@loongson.cn> Signed-off-by: Huacai Chen <chenhuacai@loongson.cn>

With hardware assisted virtualization, there are two level HW mmu, one is GVA to GPA mapping, the other is GPA to HPA mapping which is called secondary mmu in generic. If there is page fault for secondary mmu, there needs tlb flush operation indexed with fault GPA address and VMID. VMID is stored at register CSR.GSTAT and will be reload or recalculated before guest entry. Currently CSR.GSTAT is not saved and restored during VCPU context switch, instead it is recalculated during guest entry. So CSR.GSTAT is effective only when a VCPU runs in guest mode, however it may not be effective if the VCPU exits to host mode. Since register CSR.GSTAT may be stale, it may records the VMID of the last schedule-out VCPU, rather than the current VCPU. Function kvm_flush_tlb_gpa() should be called with its real VMID, so here move it to the guest entrance. Also an arch-specific request id KVM_REQ_TLB_FLUSH_GPA is added to flush tlb for secondary mmu, and it can be optimized if VMID is updated, since all guest tlb entries will be invalid if VMID is updated.

Currently interrupts are posted and cleared with the asynchronous mode, meanwhile they are saved in SW state vcpu::arch::irq_pending and vcpu:: arch::irq_clear. When vcpu is ready to run, pending interrupt is written back to CSR.ESTAT register from SW state vcpu::arch::irq_pending at the guest entrance. During VM migration stage, vcpu is put into stopped state, however pending interrupts are not synced to CSR.ESTAT register. So there will be interrupt lost when VCPU is migrated to another host machines. Here in this patch when ESTAT CSR register is read from VMM user mode, pending interrupts are synchronized to ESTAT also. So that VMM can get correct pending interrupts.

Currently building the powerpc selftests with USERCFLAGS set to anything causes the build to break: $ make -C tools/testing/selftests/powerpc V=1 USERCFLAGS=-Wno-error ... gcc -Wno-error cache_shape.c ... cache_shape.c:18:10: fatal error: utils.h: No such file or directory 18 | #include "utils.h" | ^~~~~~~~~ compilation terminated. This happens because the USERCFLAGS are added to CFLAGS in lib.mk, which causes the check of CFLAGS in powerpc/flags.mk to skip setting CFLAGS at all, resulting in none of the usual CFLAGS being passed. That can be seen in the output above, the only flag passed to the compiler is -Wno-error. Fix it by dropping the conditional setting of CFLAGS in flags.mk. Instead always set CFLAGS, but also append USERCFLAGS if they are set. Note that appending to CFLAGS (with +=) wouldn't work, because flags.mk is included by multiple Makefiles (to support partial builds), causing CFLAGS to be appended to multiple times. Additionally that would place the USERCFLAGS prior to the standard CFLAGS, meaning the USERCFLAGS couldn't override the standard flags. Being able to override the standard flags is desirable, for example for adding -Wno-error. With the fix in place, the CFLAGS are set correctly, including the USERCFLAGS: $ make -C tools/testing/selftests/powerpc V=1 USERCFLAGS=-Wno-error ... gcc -std=gnu99 -O2 -Wall -Werror -DGIT_VERSION='"v6.10-rc2-7-gdea17e7e56c3"' -I/home/michael/linux/tools/testing/selftests/powerpc/include -Wno-error cache_shape.c ...

DTS for Nokia N900 incorrectly specifies "active high" polarity for the reset line, while the chip documentation actually specifies it as "active low". In the past the driver fudged gpiod API and inverted the logic internally, but it was changed in d0d89493.
