CAN-CN FPGA: PolarFire PCIe L2P2 Link State Support
Microchip Corporation
Koko-ọrọ: CAN-CN FPGA: PolarFire PCI Express L2P2 ọna asopọ ipinle support
Apejuwe:
Ninu itusilẹ Libero SoC 2022.1 aṣayan lati mu ọna asopọ iṣakoso agbara L2P2 ti yọkuro lati Ina Ibẹrẹ SERDES GUI. Gbogbo PolarFire transceiver PCIe Link Training and Status State Machine (LTSSM) awọn bulọọki ohun elo ko ṣe atilẹyin ipo ọna asopọ iṣakoso agbara L2P2.
Idi Fun Yipada:
Awọn bulọọki transceiver PolarFire pẹlu PCIe Gen1 ti a fi sinu ati Gen2 Root-port ati awọn olutona Ipari. PCIe Sub-system (PCIESS) LTSSM ṣe atilẹyin awọn ipinlẹ Ikẹkọ Ọna asopọ ati ipo Tun-Training (Imularada). Sibẹsibẹ, PCIESS ko ṣe atilẹyin eyikeyi sọfitiwia iṣakoso agbara awọn ipinlẹ bii L2P2, bi a ti ṣe akiyesi ni aṣiṣe ninu iwe atilẹba.
- Awọn aṣẹ titẹsi L2P2 ti sọfitiwia ti a funni nipasẹ PolarFire PCIESS Root-Port si awọn aaye ipari-isalẹ ko ni atilẹyin. Gẹgẹbi ibudo-root, eyi yoo jẹ ki ọna asopọ jẹ idalọwọduro patapata ati gbigba pada nikan nipasẹ tun bẹrẹ ọna asopọ pẹlu ẹgbẹ ẹgbẹ-ẹgbẹ PERSTn (atunto ipilẹ) tabi ipa-ọna agbara kan.
- PolarFire PCIESS Ipari-ojuami ko yẹ ki o paṣẹ nipasẹ agbalejo lati tẹ ipo ọna asopọ L2P2 sii. Gẹgẹbi aaye ipari, ọna asopọ le jẹ idalọwọduro ati gbigba pada nikan nipasẹ ṣiṣatunṣe ọna asopọ pẹlu ẹgbẹ ẹgbẹ-ẹgbẹ PERSTn (atunto ipilẹ) tabi iyipo agbara kan.
Ohun elo Ipa:
Awọn ẹrọ PolarFire ko ṣe atilẹyin ipo ọna asopọ iṣakoso agbara L2P2.
- Lati yago fun awọn idalọwọduro ọna asopọ, sọfitiwia iṣakoso agbara PCIe ko gbọdọ paṣẹ fun PolarFire PCIESS Root-port tabi aaye ipari lati tẹ ipo ọna asopọ agbara kekere (L2).
- Ko ṣe aṣeyọri awọn ifowopamọ agbara iṣiṣẹ siwaju fun ẹrọ PolarFire.
- Itusilẹ Libero SoC 2022.1 ti ni imudojuiwọn lati polowo D3hot alaabo ati D3cold ni PCI Legacy Power Management ipinle ti aaye Ipari Config wa
- Lati ṣaṣeyọri awọn ifowopamọ agbara iṣẹ ṣiṣe siwaju, ni oke ti iṣapeye ẹrọ iṣapeye PolarFire ti agbara tẹlẹ, onise FPGA yẹ ki o lo awọn ilana iṣakoso agbara taara si apẹrẹ aṣọ FPGA.
Igbese Ti beere:
- Awọn olumulo yẹ ki o tọka si awọn iwe imudojuiwọn ti a pese nipasẹ Microchip nipa ọna asopọ PCIESS Atilẹyin Ipinle Ikẹkọ.

- Tọkasi Akọsilẹ Ohun elo Agbara kekere PolarFire FPGA fun awọn ẹya ẹrọ ti awọn olumulo le lo lati kọ awọn ifipamọ agbara ni afikun si apẹrẹ wọn.
