inlinestatic

#include <ee/packet2/include/packet2_chain.h>

Set dma tag. For more details, check description of dma_tag_t.

Parameters

tag	Pointer to DMA tag to set.
qwc	Qword count.
pce	Priority Control Enable. 0 by default.
id	Tag ID.
irq	Interrupt Request. False by default.
addr	Address.
spr	Memory/SPR Selection. False by default.

	)

inlinestatic

#include <ee/packet2/include/packet2_chain.h>

Add dma tag. For more details, check description of dma_tag_t. Will move current buffer position by: DWORD if packet->tte == true, QWORD if packet->tte == false

Parameters

packet2	Pointer to packet.
qwc	Qword count. If you want to use packet2_chain_close_tag(), and count qwords automatically, set value to PACKET2_COUNT_QWC.
pce	Priority Control Enable. 0 by default.
id	Tag ID.
irq	Interrupt Request. False by default.
addr	Address.
spr	Memory/SPR Selection. False by default.

◆ packet2_chain_close_tag()

static void packet2_chain_close_tag ( packet2_t * packet2 )

inlinestatic

#include <ee/packet2/include/packet2_chain.h>

Close dma tag. In reality, get back to pointer "tag_opened_at" and fix qwc value.

Parameters

packet2 Pointer to packet.

		u8	irq,
		u32	pce
	)

inlinestatic

#include <ee/packet2/include/packet2_chain.h>

Add END tag.

Note: packet2_chain_close_tag() required. Qwords are counted automatically. For more details, check description of dma_tag_t.; Don't forget about close_tag()!

Parameters
