2022-03-15whpx: Fixed incorrect CR8/TPR synchronizationIvan Shcherbakov
This fixes the following error triggered when stopping and resuming a 64-bit Linux kernel via gdb: qemu-system-x86_64.exe: WHPX: Failed to set virtual processor context, hr=c0350005 The previous logic for synchronizing the values did not take into account that the lower 4 bits of the CR8 register, containing the priority level, mapped to bits 7:4 of the APIC.TPR register (see section 10.8.6.1 of Volume 3 of Intel 64 and IA-32 Architectures Software Developer's Manual). The caused WHvSetVirtualProcessorRegisters() to fail with an error, effectively preventing GDB from changing the guest context.

2022-03-15whpx: Fixed reporting of the CPU context to GDB for 64-bitIvan Shcherbakov
Make sure that pausing the VM while in 64-bit mode will set the HF_CS64_MASK flag in env->hflags (see x86_update_hflags() in target/i386/cpu.c). Without it, the code in gdbstub.c would only use the 32-bit register values when debugging 64-bit targets, making debugging effectively impossible.

2022-03-14tcg/arm: Don't emit UNPREDICTABLE LDRD with Rm == Rt or Rt+1Richard Henderson
The LDRD (register) instruction is UNPREDICTABLE if the Rm register is the same as either Rt or Rt+1 (the two registers being loaded to). We weren't making sure we avoided this, with the result that on some host CPUs like the Cortex-A7 we would get a SIGILL because the CPU chooses to UNDEF for this particular UNPREDICTABLE case. Since we've already checked that datalo is aligned, we can simplify the test vs the Rm operand by aligning it before comparison. Check for the two orderings before falling back to two ldr instructions. We don't bother to do anything similar for tcg_out_ldrd_rwb(), because it is only used in tcg_out_tlb_read() with a fixed set of registers which don't overlap. There is no equivalent UNPREDICTABLE case for STRD.

We copied the data from the general register input to the vector register output, but have not yet replicated it. We intended to fall through into the vector-vector case, but failed to redirect the input register. This is caught by an assertion failure in tcg_out_insn_VRIc, which diagnosed the incorrect register class. Signed-off-by: Richard Henderson <richard.henderson@linaro.org>

2022-03-09esp: recreate ESPState current_req after migrationMark Cave-Ayland
Since PDMA reads/writes are driven by the guest, it is possible that migration can occur whilst a SCSIRequest is still active. Fortunately active SCSIRequests are already included in the migration stream and restarted post migration but this still leaves the reference in ESPState uninitialised. Implement the SCSIBusInfo .load_request callback to obtain a reference to the currently active SCSIRequest and use it to recreate ESPState current_req after migration.

2022-03-09macfb: set initial value of mode control registers in macfb_common_realize()Mark Cave-Ayland
If booting Linux directly in the q800 machine using -kernel rather than using a MacOS toolbox ROM, the mode control registers are never initialised, causing macfb_mode_write() to fail to determine the current resolution after migration. Resolve this by always setting the initial values of the mode control registers based upon the initial macfb properties during realize.

2022-03-09macfb: increase number of registers saved in MacfbStateMark Cave-Ayland
The MacOS toolbox ROM accesses a number of addresses between 0x0 and 0x200 during initialisation and resolution changes. Whilst the function of many of these registers is unknown, it is worth the minimal cost of saving these extra values as part of migration to help future-proof the migration stream for the q800 machine as it starts to stabilise. Note this is a migration break, but since there are upcoming incompatible changes for the q800 machine (and migration does not even succeed without these patches) then this is not an issue.

Currently when QEMU tries to migrate the macfb framebuffer it crashes randomly because the opaque provided by the DeviceClass vmsd property for both devices is set to MacfbState rather than MacfbNubusState or MacfbSysBusState as appropriate.

2022-03-09mos6522: implement edge-triggering for CA1/2 and CB1/2 control line IRQsMark Cave-Ayland
The mos6522 datasheet describes how the control lines IRQs are edge-triggered according to the configuration in the PCR register. Implement the logic according to the datasheet so that the interrupt bits in IFR are latched when the edge is detected, and cleared when reading portA/portB or writing to IFR as necessary. To maintain bisectibility this change also updates the SCSI, SCSI data, Nubus and VIA2 60Hz/1Hz clocks in the q800 machine to be negative edge-triggered as confirmed by the PCR programming in all of Linux, NetBSD and MacOS.

2022-03-09mac_via: make SCSI_DATA (DRQ) bit live rather than latchedMark Cave-Ayland
The VIA2 on the Q800 machine is not a separate chip as in older Macs but instead is integrated into the on-board logic. From analysing the SCSI routines in the MacOS toolbox ROM (and to a lesser extent NetBSD and Linux) the expectation seems to be that the SCSI_DATA (DRQ) bit is live on the Q800 and not latched. Fortunately we can use the recently introduced mos6522 last_irq_levels variable which tracks the edge-triggered state to return the SCSI_DATA (DRQ) bit live to the guest OS.
