Privileged Operations

Telkin provides the tk::privilegedWrite function-pointer to perform memory copy operations with kernel permissions.

Example:

#include <telkin/Privilege.h>
#include <telkin/Assembly.h>
 
using namespace tk::ppc;
 
void OverwriteSyscall() {
    const u32 instruction = li(GPR::r3, 0xCAFE);
    tk::privilegedWrite((const void*)0x02000000, &instruction, sizeof(u32));
}

Note

The .rodata section of RPX files is already writable, so a privileged write is unnecessary for modifying it.

See Inline Assembly for more information on the constexpr assembler used.
