2024-06-05machine: allow early use of machine_require_guest_memfdPaolo Bonzini
Ask the ConfidentialGuestSupport object whether to use guest_memfd for KVM-backend private memory. This bool can be set in instance_init (or user_complete) so that it is available when the machine is created. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2024-06-05update-linux-headers: import linux/kvm_para.h headerPaolo Bonzini
Right now QEMU is importing arch/x86/include/uapi/asm/kvm_para.h because it includes definitions for kvmclock and for KVM CPUID bits. However, other definitions for KVM hypercall values and return codes are included in include/uapi/linux/kvm_para.h and they will be used by SEV-SNP. To ensure that it is possible to include both <linux/kvm_para.h> and "standard-headers/asm-x86/kvm_para.h" without conflicts, provide linux/kvm_para.h as a portable header too, and forward linux-headers/ files to those in include/standard-headers. Note that <linux/kvm_para.h> will include architecture-specific definitions as well, but "standard-headers/linux/kvm_para.h" will not because it can be used in architecture-independent files. This could easily be extended to other architectures, but right now they do not need any symbol in their specific kvm_para.h files.

2024-06-05update-linux-headers: fix forwarding to asm-generic headersPaolo Bonzini
Afer commit 3efc75ad9d9 ("scripts/update-linux-headers.sh: Remove temporary directory inbetween", 2024-05-29), updating linux-headers/ results in errors such as cp: cannot stat '/tmp/tmp.1A1Eejh1UE/headers/include/asm/bitsperlong.h': No such file or directory because Loongarch does not have an asm/bitsperlong.h file and uses the generic version. Before commit 3efc75ad9d9, the missing file would incorrectly cause stale files to be included in linux-headers/. The files were never committed to qemu.git, but were wrong nevertheless. The build would just use the system version of the files, which is opposite to the idea of importing Linux header files into QEMU's tree. Create forwarding headers, resembling the ones that are generated during a kernel build by scripts/Makefile.asm-generic, if a file is only installed under include/asm-generic/.

2024-05-30target/arm: Implement FEAT WFxT and enable for '-cpu max'Peter Maydell
FEAT_WFxT introduces new instructions WFIT and WFET, which are like the existing WFI and WFE but allow the guest to pass a timeout value in a register. The instructions will wait for an interrupt/event as usual, but will also stop waiting when the value of CNTVCT_EL0 is greater than or equal to the specified timeout value. We implement WFIT by setting up a timer to expire at the right point; when the timer expires it sets the EXITTB interrupt, which will cause the CPU to leave the halted state. If we come out of halt for some other reason, we unset the pending timer. We implement WFET as a nop, which is architecturally permitted and matches the way we currently make WFE a nop.

2024-05-30accel/tcg: Make TCGCPUOps::cpu_exec_halt return bool for whether to haltPeter Maydell
The TCGCPUOps::cpu_exec_halt method is called from cpu_handle_halt() when the CPU is halted, so that a target CPU emulation can do anything target-specific it needs to do. (At the moment we only use this on i386.) The current specification of the method doesn't allow the target specific code to do something different if the CPU is about to come out of the halt state, because cpu_handle_halt() only determines this after the method has returned. (If the method called cpu_has_work() itself this would introduce a potential race if an interrupt arrived between the target's method implementation checking and cpu_handle_halt() repeating the check.) Change the definition of the method so that it returns a bool to tell cpu_handle_halt() whether to stay in halt or not. We will want this for the Arm target, where FEAT_WFxT wants to do some work only for the case where the CPU is in halt but about to leave it.
