I-CAN-CN FPGA: I-PolarFire PCIe L2P2 Link State Support
Inkampani Microchip Corporation
Isihloko: I-CAN-CN FPGA: I-PolarFire PCI Express L2P2 ixhumanisa ukwesekwa kombuso
Incazelo:
Ekukhishweni kwe-Libero SoC 2022.1 inketho yokunika amandla isixhumanisi sokuphatha amandla se-L2P2 isusiwe ku-Generate SERDES Initialization GUI. Wonke amabhulokhi wezingxenyekazi zekhompiyutha we-PolarFire transceiver PCIe Link Training kanye ne-Status State Machine (LTSSM) awasekeli isimo sesixhumanisi sokuphatha amandla se-L2P2.
Isizathu Soshintsho:
Amabhulokhi we-PolarFire transceiver afaka i-PCIe Gen1 eshumekiwe kanye ne-Gen2 Root-port kanye nezilawuli ze-End-point. I-PCIe Sub-system (PCIESS) LTSSM isekela i-Link Training states kanye nesimo sokuQeqesha Kabusha (Ukutakula). Kodwa-ke, i-PCIESS ayisekeli noma yiziphi izifunda zokuphatha amandla aqhutshwa yi-software njenge-L2P2, njengoba kuphawulwe ngokungalungile emibhalweni yokuqala.
- Imiyalo yokungena ye-L2P2 eqhutshwa yi-Software ekhishwe i-PolarFire PCIESS Root-Port ezindaweni zokugcina ezansi nomfula ayisekelwe. Njengembobo yezimpande, lokhu kuzobangela ukuthi isixhumanisi siphazanyiswe ngokuphelele futhi sitholakale kuphela ngokuqalisa kabusha isixhumanisi nge-side-band PERSTn (ukusetha kabusha okuyisisekelo) noma umjikelezo wamandla.
- Iphoyinti lokugcina le-PolarFire PCIESS akufanele liyalwe umsingathi ukuthi angene esimweni sokuxhumanisa i-L2P2. Njengephoyinti lokugcina, isixhumanisi singase siphazamise futhi sibuyiseke kuphela ngokuqalisa kabusha isixhumanisi nge-side-band PERSTn (ukusetha kabusha okuyisisekelo) noma umjikelezo wamandla.
Umthelela wohlelo lokusebenza:
Amadivayisi we-PolarFire awasekeli isimo sesixhumanisi sokuphathwa kwamandla we-L2P2.
- Ukuze ugweme ukuphazamiseka kwesixhumanisi, isofthiwe yokuphatha amandla ye-PCIe akumele iyale imbobo ye-PolarFire PCIESS Root-port noma i-End-point ukuze ifake isimo sokuxhumanisa amandla aphansi (L2).
- Ayizuzi okunye ukonga amandla okusebenza kudivayisi ye-PolarFire.
- Ukukhishwa kwe-Libero SoC okungu-2022.1 kwabuyekezwa ukuze kukhangiswe i-D3hot ne-D3cold ekhubazekile ku-PCI Legacy Power Management yesimo sethu se-Endpoint Config Space.
- Ukuze kuzuzwe ukonga okwengeziwe kwamandla okusebenza, phezu kwesakhiwo sedivayisi ye-PolarFire esesivele senziwe amandla, umklami we-FPGA kufanele asebenzise amasu okuphatha amandla ngokuqondile ekwakhiweni kwendwangu ye-FPGA.
Kudingeka Isenzo:
- Abasebenzisi kufanele babheke imibhalo ebuyekeziwe ehlinzekwe yi-Microchip ephathelene nesixhumanisi se-PCIESS Ukusekelwa Kwesifunda Sokuqeqesha.

Isaziso Sekhasimende (CN) noma Isaziso Sokwelulekwa Kwekhasimende (CAN) siwulwazi oluyimfihlo nolobunikazi lwe-Microchip futhi luhloselwe ukusatshalaliswa yi-Microchip kuphela kumakhasimende ayo, ukuze lusetshenziswe amakhasimende kuphela. Akumele ikopishwe noma inikezwe noma iyiphi inkampani yangaphandle ngaphandle kwemvume ebhaliwe ye-Microchip ngaphambilini.
