Platform¶

API reference for the GNM platform initialization and GPU mode query functions.

Header: platform.h

Functions¶

Returns the current GPU mode (base PS4 or NEO/Pro).

GnmGpuMode PS4_SYSV_ABI sceGnmGpuMode(void);

Returns: GnmGpuMode — the active GPU mode.

The PS4_SYSV_ABI macro ensures the function uses the PS4 System V calling convention.

Parameters passed to sceGnmPlatInit to configure the platform layer.

typedef struct {
    GnmGpuMode gpumode;
    int32_t (*getbufferlabeladdress)(
        int32_t videohandle, uint64_t* outaddr
    );
} GnmPlatParams;

Field	Type	Description
`gpumode`	`GnmGpuMode`	The target GPU mode (base or NEO)
`getbufferlabeladdress`	`int32_t ()(int32_t, uint64_t)`	Function pointer to retrieve a buffer label address for a video handle

Initializes the GNM platform layer with the supplied parameters.

void sceGnmPlatInit(GnmPlatParams* params);

Parameter	Type	Description
`params`	`GnmPlatParams*`	Platform configuration parameters

Retrieves the GPU-visible buffer label address for a given video handle. This is the function that GnmPlatParams.getbufferlabeladdress points to.

int32_t PS4_SYSV_ABI sceGnmPlatGetBufferLabelAddress(
    int32_t videohandle, uint64_t* outaddr
);

Parameter	Type	Description
`videohandle`	`int32_t`	The video handle to query
`outaddr`	`uint64_t*`	Output pointer that receives the buffer label GPU address

Returns: int32_t — zero on success, negative on error.
