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. 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.
