C910 is a 12-stage, 3 issues, 8 executions, out-of-order 64-bit RISC-V CPU which supports 16 cores, runs with 2.5GHz, and is capable of running Linux.
To build platform specific library and firmwares, provide the PLATFORM=thead/c910 parameter to the top level make command.
The T-HEAD C910 platform does not have any platform-specific options.
As there's no payload, you may download vmlinux or u-boot to FW_JUMP_ADDR which specified in config.mk or compile commands with GDB. And the execution flow will turn to vmlinux or u-boot when opensbi ends.
Linux Kernel Payload
You can also choose to use Linux kernel as payload by enabling FW_PAYLOAD=y along with specifying FW_PAYLOAD_OFFSET. The kernel image will be embedded in the OPENSBI firmware binary, T-head will directly boot into Linux after OpenSBI.
