CAN-CN FPGA: PolarFire PCIe L2P2 Link State Kākoʻo
Hui Microchip
Kumuhana: CAN-CN FPGA: PolarFire PCI Express L2P2 loulou kākoʻo mokuʻāina
wehewehe:
Ma Libero SoC hoʻokuʻu 2022.1 ke koho e hiki ai i ka L2P2 mana hoʻokele loulou ua wehe ʻia mai ka Generate SERDES Initialization GUI. ʻAʻole kākoʻo nā poloka ʻenehana ʻo PolarFire transceiver PCIe Link Training a me Status State Machine (LTSSM) i ka L2P2 power management link state.
Ke kumu o ka hoʻololi ʻana:
Hoʻokomo ʻia nā poloka transceiver PolarFire i hoʻokomo ʻia ʻo PCIe Gen1 a me Gen2 Root-port a me nā mea hoʻokele End-point. Kākoʻo ka PCIe Sub-system (PCIESS) LTSSM i nā mokuʻāina Hoʻomaʻamaʻa Link a me ka mokuʻāina Re-Training (Recovery). Eia naʻe, ʻaʻole kākoʻo ka PCIESS i nā mokuʻāina hoʻokele mana hoʻokele polokalamu e like me L2P2, e like me ka mea i ʻike hewa ʻia ma ka palapala kumu.
- ʻAʻole kākoʻo ʻia nā kauoha komo L2P2 i hoʻopuka ʻia e ka PolarFire PCIESS Root-Port i nā wahi hope o lalo. Ma ke ʻano he awa-aʻa, e hoʻopau ʻia ka loulou a hiki ke hoʻihoʻi hou ʻia ma ka hoʻomaka hou ʻana i ka loulou me ka ʻaoʻao-band PERSTn (hoʻoponopono kumu) a i ʻole ka pōʻai mana.
- ʻAʻole pono ke kauoha ʻia ʻo PolarFire PCIESS End-point e ka mea hoʻokipa e komo i ka mokuʻāina loulou L2P2. Ma ke ʻano he hopena, hiki ke hoʻopau ʻia ka loulou a hiki ke hoʻihoʻi wale ʻia ma ka hoʻomaka hou ʻana i ka loulou me ka ʻaoʻao-band PERSTn (hoʻoponopono kumu) a i ʻole ka pōʻaiapuni mana.
Ka hopena o ka noi:
ʻAʻole kākoʻo nā polokalamu PolarFire i ka mokuʻāina hoʻokele mana mana L2P2.
- No ka pale ʻana i nā loulou, ʻaʻole pono nā polokalamu hoʻokele mana ʻo PCIe e kauoha i kahi PolarFire PCIESS Root-port a i ʻole End-point e komo i kahi kūlana loulou haʻahaʻa (L2).
- ʻAʻole ia e hoʻokō hou aku i ka mālama mana hana no ka polokalamu PolarFire.
- Ua hōʻano hou ʻia ka hoʻokuʻu ʻana o Libero SoC 2022.1 e hoʻolaha i ka D3hot a me D3cold i ka mokuʻāina ʻo PCI Legacy Power Management o kā mākou Endpoint Config Space.
- No ka hoʻokō ʻana i ka mālama ʻana i ka mana, ma luna o ka hoʻolālā ʻenehana PolarFire i hoʻopaʻa ʻia i ka mana, pono ka mea hoʻolālā FPGA e hoʻohana i nā ʻenehana hoʻokele mana i ka hoʻolālā lole FPGA.
Koi ʻia ka hana:
- Pono nā mea hoʻohana e kuhikuhi i nā palapala hou i hāʻawi ʻia e Microchip e pili ana i ke kākoʻo ʻo PCIESS Link Training State.

- E nānā i ka PolarFire FPGA Low Power Application Note no nā hiʻohiʻona e hiki ai i nā mea hoʻohana ke hoʻohana no ke kūkulu ʻana i nā mana hoʻōla hou i kā lākou hoʻolālā.

Me ke aloha,
ʻO Microsemi Corporation, kahi ʻoihana nona piha o Microchip Technology Inc.
ʻO ka Customer Notice (CN) a i ʻole Customer Advisory Notice (CAN) he ʻike huna a me ka waiwai o Microchip a ua manaʻo ʻia no ka hāʻawi ʻana e Microchip i kāna mau mea kūʻai aku, no ka hoʻohana wale ʻana o nā mea kūʻai aku. ʻAʻole pono e kope ʻia a hāʻawi ʻia i kekahi ʻaoʻao ʻekolu me ka ʻole o ka palapala ʻae mua a Microchip.
