2021-03-12hw/arm/virt: KVM: The IPA lower bound is 32Andrew Jones
The virt machine already checks KVM_CAP_ARM_VM_IPA_SIZE to get the upper bound of the IPA size. If that bound is lower than the highest possible GPA for the machine, then QEMU will error out. However, the IPA is set to 40 when the highest GPA is less than or equal to 40, even when KVM may support an IPA limit as low as 32. This means KVM may fail the VM creation unnecessarily. Additionally, 40 is selected with the value 0, which means use the default, and that gets around a check in some versions of KVM, causing a difficult to debug fail. Always use the IPA size that corresponds to the highest possible GPA, unless it's lower than 32, in which case use 32. Also, we must still use 0 when KVM only supports the legacy fixed 40 bit IPA.

2021-03-11target/m68k: add M68K_FEATURE_UNALIGNED_DATA featureMark Cave-Ayland
According to the M68040UM Appendix D the requirement for data accesses to be word aligned is only for the 68000, 68008 and 68010 CPUs. Later CPUs from the 68020 onwards will allow unaligned data accesses but at the cost of being less efficient. Add a new M68K_FEATURE_UNALIGNED_DATA feature to specify that data accesses are not required to be word aligned, and don't perform the alignment on the stack pointer when taking an exception if this feature is not selected. This is required because the MacOS DAFB driver attempts to call an A-trap with a byte-aligned stack pointer during initialisation and without this the stack pointer is off by one when the A-trap returns.

2021-03-11target/m68k: don't set SSW ATC bit for physical bus errorsMark Cave-Ayland
If a NuBus slot doesn't contain a card, the Quadra hardware generates a physical bus error if the CPU attempts to access the slot address space. Both Linux and MacOS use a separate bus error handler during NuBus accesses in order to detect and recover when addressing empty slots. According to the MC68040 users manual the ATC bit of the SSW is used to distinguish between ATC faults and physical bus errors. MacOS specifically checks the stack frame generated by a NuBus error and panics if the SSW ATC bit is set. Update m68k_cpu_transaction_failed() so that the SSW ATC bit is not set if the memory API returns MEMTX_DECODE_ERROR which will be used to indicate that an access to an empty NuBus slot occurred.

2021-03-10target/ppc: Fix bcdsub. emulation when result overflowsFabiano Rosas
The commit d03b174a83 (target/ppc: simplify bcdadd/sub functions) meant to simplify some of the code but it inadvertently altered the way the CR6 field is set after the operation has overflowed. The CR6 bits are set based on the *unbounded* result of the operation, so we need to look at the result before returning from bcd_add_mag, otherwise we will look at 0 when it overflows. Consider the following subtraction: v0 = 0x9999999999999999999999999999999c (maximum positive BCD value) v1 = 0x0000000000000000000000000000001d (negative one BCD value) bcdsub. v0,v0,v1,0 The Power ISA 2.07B says: If the unbounded result is greater than zero, do the following. If PS=0, the sign code of the result is set to 0b1100. If PS=1, the sign code of the result is set to 0b1111. If the operation overflows, CR field 6 is set to 0b0101. Otherwise, CR field 6 is set to 0b0100. POWER9 hardware: vr0 = 0x0000000000000000000000000000000c (positive zero BCD value) cr6 = 0b0101 (0x5) (positive, overflow) QEMU: vr0 = 0x0000000000000000000000000000000c (positive zero BCD value) cr6 = 0b0011 (0x3) (zero, overflow) <--- wrong This patch reverts the part of d03b174a83 that introduced the problem and adds a test-case to avoid further regressions: before: $ make run-tcg-tests-ppc64le-linux-user (...)
