I-CN-CN FPGA: I-PolarFire PCIe L2P2 ikhonkco yeNkxaso yeSizwe
Inkampani yeMicrochip
Umxholo: CAN-CN FPGA: PolarFire PCI Express L2P2 link inkxaso karhulumente
Inkcazo:
Kwi-Libero SoC ikhupha i-2022.1 inketho yokwenza ukuba ikhonkco lolawulo lwamandla lwe-L2P2 lisuswe kwi-Gerate SERDES Initialization GUI. Zonke iibhloko ze-hardware ze-PolarFire transceiver PCIe Link kunye ne-Status State Machine (LTSSM) azixhasi i-L2P2 yolawulo loqhagamshelwano lwamandla.
Isizathu Sotshintsho:
Iibhloko ze-PolarFire transceiver ziquka i-PCIe Gen1 edibeneyo kunye ne-Gen2 Root-port kunye ne-End-point controllers. I-PCIe Sub-system (PCIESS) LTSSM ixhasa uQeqesho loQeqesho loQeqesho kunye noQeqesho ngokutsha (UBuyiselo). Nangona kunjalo, i-PCIESS ayixhasi naluphi na ulawulo lwamandla oluqhutywa yisoftware efana ne-L2P2, njengoko kuphawulwe ngokungachanekanga kumaxwebhu okuqala.
- Imiyalelo yokungena eqhutywa yiSoftware ye-L2P2 ekhutshwe yi-PolarFire PCIESS Root-Port ukuya kwiindawo ezisezantsi zesiphelo azixhaswanga. Njenge-root-port, oku kuya kubangela ukuba ikhonkco liphazamiseke ngokupheleleyo kwaye lifumaneke kuphela ngokuphinda kuqalise ikhonkco nge-side-band PERSTn (ukusetha ngokutsha okusisiseko) okanye umjikelo wamandla.
- I-PolarFire PCIESS Indawo yokuphela akufunekanga iyalelwe ngumamkeli ukuba angene kwi-L2P2 link state. Njengesiphelo, ikhonkco inokuphazamisa kwaye ifumaneke kuphela ngokuphinda uqalise ikhonkco kunye ne-side-band PERSTn (ukusetha ngokutsha okusisiseko) okanye umjikelo wamandla.
Impembelelo yosetyenziso:
Izixhobo zePolarFire aziyixhasi i-L2P2 yolawulo lwamandla onxibelelwano.
- Ukunqanda ukuphazamiseka kwekhonkco, isoftware yolawulo lwamandla ePCIe akufunekanga iyalele iPolarFire PCIESS Root-port okanye iEnd-point yokungena kwi-low-power link state (L2).
- Ayiphumeleli ngakumbi ukonga amandla kwisixhobo sePolarFire.
- Ukukhutshwa kweLibero SoC ngo-2022.1 kwahlaziywa ukuze kubhengezwe i-D3hot ekhubazekileyo kunye ne-D3cold kwi-PCI yeLifa leLifa loLawulo lwaMandla kwi-Endpoint Config Space yethu.
- Ukufezekisa ugcino lwamandla okusebenza ngakumbi, ngaphezulu kwesixhobo soyilo sePolarFire esenziwe amandla, umyili weFPGA kufuneka asebenzise ubuchule bolawulo lwamandla ngokuthe ngqo kuyilo lwelaphu leFPGA.
Inyathelo elifunekayo:
- Abasebenzisi kufuneka bajonge amaxwebhu ahlaziyiweyo anikezelwe yiMicrochip malunga nePCIESS ikhonkco loQeqesho lwenkxaso yeLizwe.
