2021-02-25vl: deprecate -writeconfigPaolo Bonzini3-6/+9
The functionality of -writeconfig is limited and the code does not even try to detect cases where it prints incorrect syntax (for example if values have a quote in them, since qemu_config_parse does not support any kind of escaping) so remove it. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

Bus lock debug exception is a feature that can notify the kernel by generate an #DB trap after the instruction acquires a bus lock when CPL>0. This allows the kernel to enforce user application throttling or mitigations. This feature is enumerated via CPUID.(EAX=7,ECX=0).ECX[bit 24].

Right now, recoverable sense values are only passed directly to the guest only for rerror=report.

2021-02-25hvf: Sign the code after installationAkihiko Odaki2-7/+22
Before this change, the code signed during the build was installed directly. However, the signature gets invalidated because meson modifies the code to fix dynamic library install names during the install process. It also prevents meson to strip the code because the pre-signed file is not marked as an executable (although it is somehow able to perform the modification described above). With this change, the unsigned code will be installed and modified by meson first, and a script signs it later.

2021-02-21vt82c686: Fix up power management io base and configBALATON Zoltan1-10/+12
Similar to the SMBus io registers there is a power management io range that is set via similar base address reg and enable bit. Some handling of this was already there but with several problems: using the wrong registers and bits, wrong size range, not acually updating mapping and handling reset correctly, nor emulating any of the actual io registers. Some of these errors are fixed up here. After this patch we use the correct base address register, enable bit and region size and allow guests to map/unmap this region, but we still don't emulate any of the registers in this range. PMD notes regarding the Configuration Space Power Management Registers: - 0x40 General Configuration 0 - 0x41 General Configuration 1 .

Previously just an empty RAM region was mapped on realize, now we add an empty io range logging access instead. I think the pm timer should be hooked up here but not sure guests need it. PMON on fuloong2e sets a base address but does not seem to enable region; the pegasos2 firmware pokes some regs but continues anyway so don't know if anything would make use of these facilities. Therefore this is just a clean up of previous state for now and not intending to fully implement missing functionality which could be done later if some guests need it.

2021-02-21vt82c686: Fix SMBus IO base and configuration registersBALATON Zoltan2-16/+37
The base address of the SMBus io ports and its enabled status is set by registers in the PCI config space but this was not correctly emulated. Instead the SMBus registers were mapped on realize to the base address set by a property to the address expected by fuloong2e firmware. Fix the base and config register handling to more closely model hardware which allows to remove the property and allows the guest to control this mapping. Do all this in reset instead of realize so it's correctly updated on reset.

2021-02-21vt82c686: Reorganise codeBALATON Zoltan1-139/+140
Move lines around so that object definitions become consecutive and not scattered around. This brings functions belonging to an object together so it's clearer what is defined and what parts belong to which object.

2021-02-21vt82c686: Move superio memory region to SuperIOConfig structBALATON Zoltan1-8/+8
The superio memory region holds the io space index/data registers used to access the superio config registers that are implemented in struct SuperIOConfig. To keep these related things together move the memory region to SuperIOConfig and rename it accordingly. Also remove the unused "data" member of SuperIOConfig which is not needed as we store actual data values in the regs array.

The cpu::mmr[] array contains the upper halves of 128-bit GPR registers. While they are only used by the R5900 CPU, the concept is generic and could be used by another MIPS implementation. Rename 'cpu::mmr' as 'cpu::gpr_hi' and make them global. When the code is similar to the GPR lower halves, move it close by.
