CAN-CN FPGA: PolarFire PCIe L2P2 Link State Support
Microchip Corporation
Mataupu: CAN-CN FPGA: PolarFire PCI Express L2P2 feso'ota'iga lagolago a le setete
Fa'amatalaga:
I le Libero SoC faʻasaʻo 2022.1 le filifiliga e mafai ai le fesoʻotaʻiga pulega eletise L2P2 ua aveese mai le Generate SERDES Initialization GUI. PolarFire transceiver PCIe Link Training and Status State Machine (LTSSM) poloka meafaigaluega e le lagolagoina le L2P2 power management link state.
Mafuaaga mo Suiga:
O poloka transceiver PolarFire e aofia ai le PCIe Gen1 ma le Gen2 Root-port ma le End-point controllers. O le PCIe Sub-system (PCIESS) LTSSM e lagolagoina le So'otaga a'oa'oga setete ma le Toe A'oa'oga (Toe Fa'afouga). Ae ui i lea, e le lagolagoina e le PCIESS soʻo se faʻatonuina o le pulega o le mana e pei o le L2P2, e pei ona taʻua sese i le uluai faʻamaumauga.
- L2P2 fa'apolokalame fa'aosoina tulafono fa'aulu e tu'uina atu e le PolarFire PCIESS Root-Port i pito pito i lalo e le o lagolagoina. I le avea ai o se root-port, o le a mafua ai ona faʻalavelaveina le soʻotaga ma e naʻo le toe faʻaleleia e ala i le toe amataina o le soʻotaga i le itu-band PERSTn (faʻavaeina faʻavae) poʻo se taamilosaga eletise.
- PolarFire PCIESS End-point e le tatau ona faʻatonuina e le talimalo e ulufale i le L2P2 soʻotaga setete. I le avea ai o se fa'ai'uga, o le so'oga e ono fa'alavelave ma e na'o le toe fa'afo'isia o le so'oga i le itu-band PERSTn (fa'atonu fa'avae) po'o se ta'amilosaga malosi.
Aafiaga ole Fa'aoga:
PolarFire masini e le lagolagoina L2P2 pulega malosiaga so'otaga tulaga.
- Ina ia aloese mai faʻalavelave fesoʻotaʻiga, e le tatau ona faʻatonuina e le PCIe le power management software se PolarFire PCIESS Root-port poʻo le End-point e ulufale ai i se tulaga o fesoʻotaʻiga maualalo (L2).
- E le maua ai nisi fa'aolaga fa'aola mo le masini PolarFire.
- Libero SoC fa'amalolo 2022.1 na fa'afouina e fa'asalalau D3hot ma D3cold fa'aletonu i le PCI Legacy Power Management state o la tatou Endpoint Config Space
- Ina ia ausia atili le faʻaogaina o le eletise, i luga o le fausaga o masini PolarFire ua uma ona faʻaogaina le malosi, e tatau i le faʻailoga FPGA ona faʻaogaina auala faʻatautaia saʻo i le mamanu ie FPGA.
Gaioiga Manaomia:
- E tatau i tagata fa'aoga ona fa'asino i fa'amaumauga fa'afou na tu'uina mai e Microchip e uiga i le PCIESS feso'ota'iga lagolago a le Setete.

- Va'ai i le PolarFire FPGA Low Power Application Note mo foliga o masini e mafai ona fa'aogaina e tagata fa'aoga e fausia ai le fa'aputuga o le paoa i totonu o latou mamanu.

Tagata Fa'asilasilaga (CN) po'o le Customer Advisory Notice (CAN) o fa'amatalaga fa'alilolilo ma fa'apitoa a le Microchip ma e fa'amoemoe mo na'o le tufatufaina atu e le Microchip i ana tagata fa'atau, mo na'o le fa'aogaina e tagata fa'atau. E le tatau ona kopiina pe tu'uina atu i so'o se isi vaega e aunoa ma se fa'atagaga tusitusia muamua a le Microchip.
