This patch series introduce support for the new-generation Hygon
model 4h~8h processors, addressing five key areas:
1. CPU Topology Updates
The new processor introduces a revised CPU topology hierarchy
compared to previous generations. This patch updates the kernel's
topology detection logic to correctly identify core/socket
relationships and cache sharing patterns.
2. L3 Performance Monitoring Updates
The L3 perf registers of model 6h differ from those of the
previous processor.
3. Microcode loading
Add microcode loading support for Hygon processor.
4. Audio Controller Driver
Add initial support for the integrated HD-Audio controller.
5. New SB IOAPIC information support
The southbridge IOAPIC of Hygon's new-generation processors is
located at 00:0b.0.
