047da861f9 target/riscv: Introduce extension implied rule helpers
Introduce helpers to enable the extensions based on the implied rules.
The implied extensions are enabled recursively, so we don't have to
expand all of them manually. This also eliminates the old-fashioned
ordering requirement. For example, Zvksg implies Zvks, Zvks implies
Zvksed, etc., removing the need to check the implied rules of Zvksg
before Zvks.

f04f770920 target/riscv: Introduce extension implied rules definition
RISCVCPUImpliedExtsRule is created to store the implied rules.
'is_misa' flag is used to distinguish whether the rule is derived
from the MISA or other extensions.
'ext' stores the MISA bit if 'is_misa' is true. Otherwise, it stores
the offset of the extension defined in RISCVCPUConfig. 'ext' will also
serve as the key of the hash tables to look up the rule in the following
commit.

c165408779 target/riscv: fix instructions count handling in icount mode
When icount is enabled, rather than returning the virtual CPU time, we
should return the instruction count itself. Add an instructions bool
parameter to get_ticks() to correctly return icount_get_raw() when
icount_enabled() == 1 and instruction count is queried. This will modify
the existing behavior which was returning an instructions count close to
the number of cycles (CPI ~= 1).

4406ba2b5e hw/riscv/virt.c: Make block devices default to virtio
RISC-V virt is currently missing default type for block devices. Without
this being set, proper backend is not created when option like -cdrom
is used. So, make the virt board's default block device type be
IF_VIRTIO similar to other architectures.

We also need to set no_cdrom to avoid getting a default cdrom device.

80b605056d target/riscv/kvm: add software breakpoints support
This patch implements insert/remove software breakpoint process.

For RISC-V, GDB treats single-step similarly to breakpoint: add a
breakpoint at the next step address, then continue. So this also
works for single-step debugging.

Implement kvm_arch_update_guest_debug(): Set the control flag
when there are active breakpoints. This will help KVM to know
the status in the userspace.

Add some stubs which are necessary for building, and will be
implemented later.

92c82a126e target/riscv: Move Guest irqs out of the core local irqs range.
Qemu maps IRQs 0:15 for core interrupts and 16 onward for
guest interrupts which are later translated to hgiep in
`riscv_cpu_set_irq()` function.

With virtual IRQ support added, software now can fully
use the whole local interrupt range without any actual
hardware attached.

This change moves the guest interrupt range after the
core local interrupt range to avoid clash.

504d297e10 vfio/container: Change VFIOContainerBase to use QOM
VFIOContainerBase was made a QOM interface because we believed that a
QOM object would expose all the IOMMU backends to the QEMU machine and
human interface. This only applies to user creatable devices or objects.

Change the VFIOContainerBase nature from interface to object and make
the necessary adjustments in the VFIO_IOMMU hierarchy.

9550fdfd29 vfio/container: Discover IOMMU type before creating the container

from the IOMMU type exposed by the host, this type should be well
defined *before* creating the container struct. This will be necessary
to instantiate a QOM object of the correct type in future changes.

Rework vfio_set_iommu() to extract the part doing the container
initialization and move it under vfio_create_container().

Assign the base container VFIOAddressSpace 'space' pointer in

vfio_container_init() and instead rely on an .instance_init() handler

To be noted that vfio_connect_container() will assign the 'space'
