atp. a sypu si popel na hlavu, uz jsem zjistil, ze raw api nelze
volat z jineho vlakna...<br>
S pouzitim netconn vse za se funguje k plne spokojenosti... Kdyz
uz je tu tak mrtvo, treba to nekomu pomuze ;-)<br>

<div class="moz-cite-prefix">Tak zpet, to ani tak klicove neni,
dulezitejsi je zavolat tcp_output(pcb), bez toho to posle az po
nejakem timeoutu, i kdyz jsou plne buffery<br>
<br>
Co je horsi, je stabilita, pokud posilam data max. rychlosti,
dojde po case k zacykleni, coz me trosku znervoznuje... Proto
ten delay.<br>
<br>
Jeste jsem zmenil princip cekani na pakety v
ethernetif.c/ethernetif_input, je tam binarni semafor, tak kdyz
to nestihne oblouzit do prichodu dalsiho paketu, ztrati se
informace a pakety se zacnou "courat" zpozdene. Zmenil jsem ho
na pocitaci a pocet bufferu zvetsil ze 4 -> 8<br>
<br>
Ma nekdo nejake hlubsi zkusenosti jak to dal stabilizovat? <br>
<br>
<br>
Nejstabilnejsi vysledky dava tento program ale stejne se dosahne
jenom cca 500kB/s: (s optimalizovanym prekladem 1MB pokud delay
zmensim na 1ms, ale Yield nestaci a stejne se to po cca 300MB
sekne...)<br>

<br>
<br>
mam problem s implementaci subj, pouziva HAL, vse
nakonfigurovano pokusne v prazdnem projektu. <br>
<br>
Aplikace pouze odesila data po pripojeni klienta, prenosova
rychlost je zoufala, asi 1kB/s.... Netusi nekdo, v cem muze
byt problem? Asi malo nejakych bufferu? Ale experimenty nikam
nevedly. <br>
<br>
Pres switch to chodi asi 3x rychleji nez primo pripojene k PC,
asi to servisni komunikace nejak zahlti? Nebo delam neco
spatne? <br>
<br>
Sledovana komunikace ale vypada plynula bez komplikaci, .123
je PC, .9 STM, viz priloha <br>
