| Remote Procedure Call Implementation |
| ==================================== |
| |
| Certain features from the standard C library, such as allocation or printing, |
| require support from the operating system. We instead implement a remote |
| procedure call (RPC) interface to allow submitting work from the GPU to a host |
| server that forwards it to the host system. |
| |
| Extensions |
| ---------- |
| |
| We describe which operation the RPC server should take with a 16-bit opcode. We |
| consider the first 32768 numbers to be reserved while the others are free to |
| use. |
