Peter Maydell 75c9a1a047 target-arm: Implement vCPU reset via KVM_ARM_VCPU_INIT for 32-bit CPUs
Implement kvm_arm_vcpu_init() as a simple call to arm_arm_vcpu_init()
(which uses the KVM_ARM_VCPU_INIT vcpu ioctl to tell the kernel
to re-initialize the vCPU), rather than via the complicated code
which saves a copy of the register state on first init and then
writes it back to the kernel. This is much simpler and brings the
32-bit KVM code into line with the 64-bit code.

Pranavkumar Sawargaonkar dd032e3487 target-arm: Introduce per-CPU field for PSCI version
We require to know the PSCI version available to given CPU at
potentially many places. Currently, we need to know PSCI version
when generating DTB for virt machine.

This patch introduce per-CPU 32bit field representing the PSCI
version available to the CPU. The encoding of this 32bit field
is same as described in PSCI v0.2 spec.

To implement kvm_arch_reset_vcpu(), we simply re-init the VCPU

Pranavkumar Sawargaonkar 7cd62e5384 target-arm: Enable KVM_ARM_VCPU_PSCI_0_2 feature when possible
Latest linux kernel supports in-kernel emulation of PSCI v0.2 but
to enable it we need to select KVM_ARM_VCPU_PSCI_0_2 feature using
KVM_ARM_VCPU_INIT ioctl.

Also, we can use KVM_ARM_VCPU_PSCI_0_2 feature for VCPU only when
linux kernel has KVM_CAP_ARM_PSCI_0_2 capability.

This patch updates kvm_arch_init_vcpu() to enable KVM_ARM_VCPU_PSCI_0_2
feature for VCPU when KVM ARM/ARM64 has KVM_CAP_ARM_PSCI_0_2 capability.

In handle_simd_shift_fpint_conv(), the combination of is_double == true,
is_scalar == false and is_q == false is an unallocated encoding; the

Peter Maydell d3afacc726 target-arm: Fix errors in writes to generic timer control registers
The code for handling writes to the generic timer control registers
had several bugs:
 * ISTATUS (bit 2) is read-only but we forced it to zero on any write
 * the check for "was IMASK (bit 1) toggled?" incorrectly used '&' where
   it should be '^'
 * the handling of IMASK was inverted: we should set the IRQ if
   ISTATUS is set and IMASK is clear, not if both are set

The combination of these bugs meant that when running a Linux guest
that uses the generic timers we would fairly quickly end up either
forgetting that the timer output should be asserted, or failing to
set the IRQ when the timer was unmasked. The result is that the guest
never gets any more timer interrupts.

Ian Campbell d615efac7c target-arm: Correct handling of UXN bit in ARMv8 LPAE page tables
In v8 page tables bit 54 in the PTE is UXN in the EL0/EL1 translation regimes
and XN elsewhere. In v7 the bit is always XN. Since we only emulate EL0/EL1 we
can just treat this bit as UXN whenever we are in v8 mode.

Also correctly extract the upper attributes from the PTE entry, the v8 version
tried to avoid extracting the CONTIG bit and ended up with the upper bits being
off-by-one. Instead behave the same as v7 and extract (but ignore) the CONTIG
bit.

This fixes "Bad mode in Synchronous Abort handler detected, code 0x8400000f"
seen when modprobing modules under Linux.
