cppi5_desc_is_tdcm(9)
β¨ NAME β¨
okay so bestie, welcome to cppi5_desc_is_tdcm(9) from the Kernel API Manual β this is the little icon that checks if the paddr indicates a Teardown Complete Message. it's giving tiny-but-important kernel helper energy, and honestly? we love to see it. π
πΈ SYNOPSIS πΈ
the whole vibe is literally this one call:
bool cppi5_desc_is_tdcm (dma_addr_t paddr );
π ARGUMENTS π
paddrβ Physical address of the packet popped from the ring. yes bestie, that exact one. π«Ά
π RETURN π
it hands you back true if the address indicates TDCM. no cap. β¨
