Some key consideration: - Only place BigCore which is 1.6GHz RV64GCBV The existence of cache coherence between the two cores remains unknown since they have dedicated L2 caches. And the factory SDK uses it for other OS by default. I don't know whether the two CPUs on K230 SoC can be used in one system. So only place BigCore here. Meanwhile, although docs from Canaan said 1.6GHz Core with Vector is CPU1, the CSR.MHARTID of this core is 0. - Support for "zba" "zbb" "zbc" "zbs" are tested by hand The user manual of C908 from T-Head does not document it specifically. It just said it supports B extension V1.0. [2] I have tested it by using this [3] which attempts to execute "add.uw", "andn", "clmulr", "bclr" and they doesn't traps on K230. But on JH7110, "clmulr" and "bclr" will trap. - Support for "zicbom" is tested by hand Have tested with some out-of-tree drivers from [4] that need DMA and they do not come to the dts currently. - Cache parameters are inferred from T-Head docs [2] and Canaan docs [1] L1i: 32KB, VIPT 4-Way set-associative, 64B Cacheline L1d: 32KB, VIPT 4-Way set-associative, 64B Cacheline L2: 256KB, PIPT 16-way set-associative, 64B Cacheline The numbers of cache sets are calculated from these parameters. - MMU only supports Sv39 The T-Head docs [2] say the C908 core can be configured to support Sv48 and Sv39 or only Sv39. On K230, I tried to write "riscv,sv48" on mmu-type in dts and boot the mainline kernel. However, it failed during the kernel probe and fell back to Sv39. I also tested it on M-Mode software, writing Sv48 to satp.mode will not trap but will leave the CSR unchanged. While writing Sv39, it will take effect. It shows that this CPU does not support Sv48. - Svpbmt and T-Head MAEE both supported T-Head C908 does support both Svpbmt and T-Head MAEE for page-based memory attributes and is controlled by BIT(21) on CSR.MXSTATUS. The Svpbmt is used here for mainline kernel support for K230. If the kernel wants to use Svpbmt, the M-Mode software should unset BIT(21) of CSR.MXSTATUS before entering the S-Mode kernel. Otherwise, the kernel will not boot, as 0 on T-Head MAEE is NonCachable Memory. Once the kernel switches from bare metal to Sv39, It will lose dirty cache line modifications that haven't been written back to the memory.
