mehrdadh opened a new pull request, #13885:
URL: https://github.com/apache/tvm/pull/13885
This PR refactors all the necessary function fors a CRT project into
`platform-template.c`/`platfrom-template.h` files. Using this PR the content of
CRT template project is as follow:
```
.
├── include
│ ├── crt_config-template.h
│ └── platform-template.h
├── Makefile.template
├── microtvm_api_server.py
└── src
├── main.cc
└── platform-template.c
```
The content of platform-template.c is as follows. This file shows the
minimum implementation that is required for using a microTVM generated MLF file
in a different environment.
```
#include <stdarg.h>
#include <stdint.h>
#include <stdio.h>
#include <stdlib.h>
#include "dlpack/dlpack.h"
#include "tvm/platform.h"
#include "tvm/runtime/crt/error_codes.h"
// Called by TVM when a message needs to be formatted.
__attribute__((weak)) size_t TVMPlatformFormatMessage(char* out_buf, size_t
out_buf_size_bytes,
const char* fmt,
va_list args) {
return vsprintf(out_buf, fmt, args);
}
// Called by TVM when an internal invariant is violated, and execution
cannot continue.
__attribute__((weak)) void TVMPlatformAbort(tvm_crt_error_t error_code) {
exit(1); }
// Called by TVM when memory allocation is required.
__attribute__((weak)) tvm_crt_error_t TVMPlatformMemoryAllocate(size_t
num_bytes, DLDevice dev,
void**
out_ptr) {
return memory_manager->Allocate(memory_manager, num_bytes, dev, out_ptr);
}
// Called by TVM to free an allocated memory.
__attribute__((weak)) tvm_crt_error_t TVMPlatformMemoryFree(void* ptr,
DLDevice dev) {
return memory_manager->Free(memory_manager, ptr, dev);
}
```
Using the same idea, various project types for Zephyr was refactored.
In addition. these templates files are also added along with
`crt_config-template.h` (which was accidentally removed in #13812) to model
library format. Here is the updated structure of a MLF file:
```
.
├── codegen
│ └── host
├── metadata.json
├── parameters
│ └── default.params
├── runtime
│ ├── include
│ ├── Makefile
│ └── src
├── src
│ └── default.relay
└── templates
├── crt_config-template.h
├── platform-template.c
└── platform-template.h
```
