[PULL v2 2/6] target/loongarch: Use actual operand size with vbsrl check
1
Hardcoded 32 bytes is used for vbsrl emulation check, there is
2
problem when options lsx=on,lasx=off is used for vbsrl.v instruction
3
in TCG mode. It injects LASX exception rather LSX exception.

Here actual operand size is used.

[PULL v2 3/6] hw/loongarch/virt: Create fdt table on machine creation done notification
1
The same with ACPI table, fdt table is created on machine done
2
notification. Some objects like CPU objects can be created with cold-plug
3
method with command such as -smp x, -device la464-loongarch-cpu, so all
4
objects finish to create when machine is done.

[PULL v2 4/6] hw/loongarch/virt: Improve fdt table creation for CPU object
1
For CPU object, possible_cpu_arch_ids() function is used rather than
2
smp.cpus. With command -smp x, -device la464-loongarch-cpu, smp.cpus
3
is not accurate for all possible CPU objects, possible_cpu_arch_ids()
4
is used here.

[PULL 1/2] target/loongarch: fix ASXE flag conflict
[PULL v2 5/6] target/loongarch: Use auto method with LSX feature
1
From: Jiajie Chen <c@jia.je>
1
Like LBT feature, add type OnOffAuto for LSX feature setting. Also
2
add LSX feature detection with new VM ioctl command, fallback to old
3
method if it is not supported.

3
HW_FLAGS_EUEN_ASXE acccidentally conflicts with HW_FLAGS_CRMD_PG,

4
enabling LASX instructions even when CSR_EUEN.ASXE=0.
