2021-07-23i386: do not call cpudef-only models functions for max, host, baseClaudio Fontana4-59/+89
Some cpu properties have to be set only for cpu models in builtin_x86_defs, registered with x86_register_cpu_model_type, and not for cpu models "base", "max", and the subclass "host". These properties are the ones set by function x86_cpu_apply_props, (also including kvm_default_props, tcg_default_props), and the "vendor" property for the KVM and HVF accelerators. After recent refactoring of cpu, which also affected these properties, they were instead set unconditionally for all x86 cpus. This has been detected as a bug with Nested on AMD with cpu "host", as svm was not turned on by default, due to the wrongful setting of kvm_default_props via x86_cpu_apply_props, which set svm to "off". Rectify the bug introduced in commit "i386: split cpu accelerators" and document the functions that are builtin_x86_defs-only.

2021-07-21target/hexagon: Drop include of qemu.hPeter Maydell1-1/+2
The qemu.h file is a CONFIG_USER_ONLY header; it doesn't appear on the include path for softmmu builds. Currently we include it unconditionally in target/hexagon/op_helper.c. We used to need it for the put_user_*() and get_user_*() functions, but now that we have removed the uses of those from op_helper.c, the only reason it's still there is that we're implicitly relying on it pulling in some other headers. Explicitly include the headers we need for other functions, and drop the include of qemu.h.

Using offsetoflow32 in this case breaks big-endian hosts. For TTBCR2, we do want the high 32-bits of a uint64_t. Use cp15.tcr_el[*].raw_tcr as the offsetofhigh32 argument to clarify this.

2021-07-13i386: hardcode supported eVMCS version to '1'Vitaly Kuznetsov1-4/+35
Currently, the only eVMCS version, supported by KVM (and described in TLFS) is '1'. When Enlightened VMCS feature is enabled, QEMU takes the supported eVMCS version range (from KVM_CAP_HYPERV_ENLIGHTENED_VMCS enablement) and puts it to guest visible CPUIDs. When (and if) eVMCS ver.2 appears a problem on migration is expected: it doesn't seem to be possible to migrate from a host supporting eVMCS ver.2 to a host, which only support eVMCS ver.1. Hardcode eVMCS ver.1 as the result of 'hv-evmcs' enablement for now. Newer eVMCS versions will have to have their own enablement options (e.g. 'hv-evmcs=2').

2021-07-11target/mips: Rewrite UHI errno_mips() using switch statementPhilippe Mathieu-Daudé1-15/+9
Linking on Haiku OS fails: /boot/system/develop/tools/bin/../lib/gcc/x86_64-unknown-haiku/8.3.0/../../../../x86_64-unknown-haiku/bin/ld: error: libqemu-mips-softmmu.fa.p/target_mips_tcg_sysemu_mips-semi.c.o(.rodata) is too large (0xffff405a bytes) /boot/system/develop/tools/bin/../lib/gcc/x86_64-unknown-haiku/8.3.0/../../../../x86_64-unknown-haiku/bin/ld: final link failed: memory exhausted collect2: error: ld returned 1 exit status This is because the host_to_mips_errno[] uses errno as index, for example: static const uint16_t host_to_mips_errno[] = { [ENAMETOOLONG] = 91, ... and Haiku defines [*] ENAMETOOLONG as: 12 /* Error baselines */ 13 #define B_GENERAL_ERROR_BASE INT_MIN .. 22 #define B_STORAGE_ERROR_BASE (B_GENERAL_ERROR_BASE + 0x6000) ... 106 #define B_NAME_TOO_LONG (B_STORAGE_ERROR_BASE + 4) ... 211 #define ENAMETOOLONG B_TO_POSIX_ERROR(B_NAME_TOO_LONG) so the array ends up beeing indeed too big. Since POSIX errno can't be use as indexes on Haiku, rewrite errno_mips() using a switch statement.
