β¨ vb2_verify_memory_type in the Kernel API Manual β¨π
okay so bestie, welcome to this lil page from the Kernel API Manual β todayβs main character is vb2_verify_memory_type, and she is literally here to do a compatibility vibe check. π«Ά
πΈ NAME πΈ
vb2_verify_memory_type β checks whether the memory type and buffer type passed to a buffer operation are compatible with the queue. no cap. π
π¦ SYNOPSIS π¦
int vb2_verify_memory_type (struct vb2_queue *q , enum vb2_memory memory
, unsigned int type );
π ARGUMENTS π
qβ pointer tostruct vb2_queuewith videobuf2 queue. this is the queue bestie in question, periodt. πmemoryβ the memory model, as defined byenum vb2_memory. literally the memory vibe check. π§typeβ private buffer type whose content is defined by the vb2-core caller. For example, for V4L2, it should match the types defined onenum v4l2_buf_type. iykyk. π
