This patch series introduce support for the new-generation Hygon
processor models 0x4–0x8, 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.
v2->v3:
- Refine the commit messages for patch x86/cpu/hygon.
- Update the logic for deriving the LLC ID from the APIC ID on Hygon
processors.
- Clean up and refine Hygon microcode support code.
- Refine the code of Hygon HD-Audio device ID.
- The iommu/hygon patch has been accepted and merged into iommu branch.
v1->v2:
- Refine the patch x86/cpu/hygon.
- Do a separate compilation unit on hygon microcode loading support.
- Use "access_sdnctl_in_dword" instead of "hygon_dword_acess" for
accessing the HDA registers.
