T-HEAD C910 Processor
|
|
=====================
|
|
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.
|
|
|
|
Platform Options
|
|
----------------
|
|
|
|
The *T-HEAD C910* platform does not have any platform-specific options.
|
|
|
|
Building T-HEAD C910 Platform
|
|
-----------------------------
|
|
|
|
```
|
|
make PLATFORM=thead/c910
|
|
```
|
|
|
|
Booting T-HEAD C910 Platform
|
|
-----------------------------
|
|
|
|
**No Payload**
|
|
|
|
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.
