Raws li koj qhov kev tsom mus rau yav dhau los ntawm PTP hardware timestamp scenario nyob rau hauv ib puag ncig Linux, ntawm no yog ib txoj hauv kev rau kev txhim kho network daim npav tsav tsheb, sib xws nrog feem ntau cov npav network uas txhawb cov khoom siv sijhawm, tsis tas yuav hloov kho rau cov qauv tshwj xeeb:
I. Cov kauj ruam npaj
Ua ntej, paub meej tias koj tus qauv daim npav network. Rub tawm cov ntaub ntawv sib xws PTP- cov pob tshwj xeeb tsav tsheb los ntawm lub hom phiaj lub vev xaib. Tsis txhob siv lub system lub neej ntawd tsav tsheb.
Nruab Linux compilation dependencies: Execute `sudo apt install build-tseem ceeb linux-headers-$(unname -r)` kom phim cov ntaub ntawv kernel header tam sim no.
II. General installation cov kauj ruam
Uninstall tus neeg tsav tsheb qub: Ua kom 'sudo rmmod qub tsav tsheb module lub npe' kom tshem tawm lub kaw lus lub neej ntawd tsav tsheb thiab zam kev tsis sib haum xeeb.
Unzip tus tsav tsheb qhov pob, nkag mus rau hauv phau ntawv qhia, ua 'ua' los sau, thiab tom qab ntawd ua tiav 'sudo ua teeb tsa' kom ua tiav kev teeb tsa.
Load tus tsav tsheb tshiab: Ua kom tiav 'sudo modprobe tshiab tus tsav tsheb module lub npe', thiab rov pib qhov kev pabcuam network card.
III. Txheeb xyuas qhov ua tiav Ua tiav 'ethtool -T network_interface_name`. Yog hais tias cov zis muaj xws li cov teb uas muaj feem xyuam rau lub hardware timestamp, thiab lub system generates lub '/dev/ptp0' node, ces lub installation tiav.
Txoj kev no yog sib xws nrog ntau dua 90% ntawm cov ntawv xov xwm kev lag luam nrog PTP cov ntawv teev sijhawm kho vajtse, tshem tawm qhov xav tau los nrhiav kev qhia tshwj xeeb rau cov qauv tshwj xeeb.
