CAN-CN FPGA: PolarFire PCIe L2P2 Link State Support
Malingaliro a kampani Microchip Corporation
Mutu: CAN-CN FPGA: PolarFire PCI Express L2P2 yolumikizira boma thandizo
Kufotokozera:
Mu Libero SoC kutulutsa 2022.1 mwayi woti ulalo wowongolera mphamvu wa L2P2 wachotsedwa pa Generate SERDES Initialization GUI. Ma block onse a PolarFire transceiver PCIe Link Training ndi Status State Machine (LTSSM) sizigwirizana ndi ulalo wa ulalo wamagetsi wa L2P2.
Chifukwa Chosinthira:
Ma block transceiver a PolarFire akuphatikiza ophatikizidwa a PCIe Gen1 ndi Gen2 Root-port ndi olamulira a End-point. PCIe Sub-system (PCIESS) LTSSM imathandizira maiko a Link Training ndi Re-Training (Recovery) state. Komabe, PCIESS sichigwirizana ndi mapulogalamu aliwonse omwe amayendetsedwa ndi mapulogalamu monga L2P2, monga momwe zalembedwera molakwika pazolemba zoyambirira.
- Malamulo olowera a L2P2 oyendetsedwa ndi mapulogalamu operekedwa ndi PolarFire PCIESS Root-Port mpaka kumapeto kwa mtsinje sakuthandizidwa. Monga doko la mizu, izi zipangitsa kuti ulalowo usokonezeke kwathunthu ndikungobwezeretsedwanso poyambitsanso ulalo ndi gulu la mbali PERSTn (kukonzanso koyambira) kapena kuzungulira kwamagetsi.
- PolarFire PCIESS End-point sayenera kulamulidwa ndi wolandirayo kuti alowe mu L2P2 link state. Monga pomalizira, ulalo ukhoza kukhala wosokoneza ndikungobwezeredwa poyambitsanso ulalowo ndi gulu lakumbali PERSTn (kukonzanso koyambira) kapena kuzungulira kwamagetsi.
Zokhudza Ntchito:
Zida za PolarFire sizigwirizana ndi ulalo wa L2P2 wowongolera mphamvu.
- Kuti mupewe kusokonezeka kwa maulalo, pulogalamu yoyang'anira mphamvu ya PCIe sayenera kulamula PolarFire PCIESS Root-port kapena End-point kuti ilowe m'malo olumikizira mphamvu zochepa (L2).
- Sichikwaniritsanso kupulumutsa mphamvu kwa chipangizo cha PolarFire.
- Libero SoC kutulutsidwa kwa 2022.1 kudasinthidwa kuti alengeze D3hot yolumala ndi D3cold mu PCI Legacy Power Management state ya Endpoint Config Space yathu.
- Kuti akwaniritse kupulumutsanso mphamvu zogwirira ntchito, pamwamba pa zida zokonzedwa kale za PolarFire, wopanga FPGA ayenera kugwiritsa ntchito njira zowongolera mphamvu mwachindunji pamapangidwe a nsalu ya FPGA.
Zofunika Kuchita:
- Ogwiritsa ntchito akuyenera kuyang'ana zolemba zosinthidwa zoperekedwa ndi Microchip zokhudzana ndi ulalo wa PCIESS Training State thandizo.

- Onani za PolarFire FPGA Low Power Application Note ya zida zomwe ogwiritsa ntchito angagwiritse ntchito kuti awonjezere kupulumutsa mphamvu pamapangidwe awo.
