Konecne jsem se dostal k nasledujicimu problemu:
na mem 7.0-RELEASE-p5 (dmesg dole) mi sitovka vr0
pri vetsim trafficu rika
vr0: watchdog timeout
Me to dela vge0 na 6.3, vetsi traffic na to ani nepotrebuje a zapnuti
poolingu situaci zhorsi - nejenze "timeouty" nezmizi, ale v tehle
konfiguraci se z toho stavu navic nedokaze vzpamatovat.
Jeste jsem to ale neresil, nejdriv se budu venovat tomu, proc nejde
vypnout hardwarova akcelerace (txcsum/rxcsum), ktera se jim po nejake
dobe provozu taky podela a pak nektere pakety neprochazeji (protoze jim
karta spocita blbe checksum).
Nicmene, i kdybych to resil, asi by ti to stejne nepomohlo - pres
urcitou podobnost v priznacich to nejspis nebude stejny problem.
ifconfig vr0 ... polling
v nastaveni interfacu. Tim prvni problem skutecne zmizel, tj. sitove
prodlevy a hlaska o "watchdog timeout" zmizely, nicmene zustava mi tato
otazka: (nove) dmesg rika o moji vr0 toto (stare dmesg pokracovalo
sekvenci hlasek "vr0: watchdog timeout"):
vr0: <VIA VT6102 Rhine II 10/100BaseTX> port 0xd400-0xd4ff mem
0xdffffe00-0xdffffeff irq 23 at device 18.0 on pci0
vr0: Quirks: 0x0
...
vr0: using obsoleted if_watchdog interface
vr0: Ethernet address: 00:0c:76:55:85:56
vr0: [ITHREAD]
1) Co jsou quirks?
V tomto pripade je vyznam "bitiky oznacujici potrebu specialniho chovani
v konkretni situaci". Ovladac vr0 ve skutecnosti podporuje vic ruznych
karet, ktere jsou si sice hodne podobne, ale nejsou preci jen uplne
stejne - nektere maji hardwarove pocitani checksumu, nektere vyzaduji
aby predavana data byla jen na zarovannych adresach, ...
Tak tyhle bitiky obsahuji informace o tehle "zvlastnich" pozadavcich
konkretni karty.
2) Znamena "obsoleted if_watchdog interface", ze zrovna vr driver
pouziva obsoleted if_watchdog interface, zatimco jine drivery
pouzivaji if_watchdog intarface, ktery neni obsoleted,
anebo to znamena, ze if_watchdog interface jako takovy
je obsoleted? Podle /usr/src/sys/net/if.c, ktere rika
if (ifp->if_watchdog != NULL)
if_printf(ifp, "using obsoleted if_watchdog interface\n");
bych rekl, ze spis to druhe.
No, ja v tom nevidim velky rozdil - jestli existuje stare interface a
nove interface a ovladac pouziva stare, pak je skoro jiste stary. A nebo
je sice novy, ale programator ma "stare" znalosti, coz je z hlediska
vysledku takrka totez ...
3) Jelito skutecne tak, znamena to pro me neco? V krajnim pripade,
je snad v nejakem ohledu lepsi pouzivat kartu, ktera (resp: jejiz driver)
nepouziva tento obsoleted interface?
Urcite to neco znamena. "Stary" ovladac znamena, ze tu kartu moc lidi
nepouziva. nebo, ze neco jineho brani "udrzbe" ovladacu. To znamena, ze
karta je pravdepodobne mene vyzkousena, takze tam s vyssi
pravdepodobnosti budou ruzne chyby (na ktere se kvuli male pouzivanosti
dosud neprislo). Nebo prislo, ale protoze neco brani udrzbe ovladace,
zustavaji neopravene.
Ovladac pro VR je podle vseho dlouhodobe neudrzovany, maximalne se do
nej dobastli to, co je potrebne, aby fungoval na nove verzi FreeBSD -
dosud dokonce ani neni presunut v adresarove strukture k ostatnim
ovladacum sitovek a zustava tam, kde ovladace byly kdysi.
Otazka, jestli to znamena neco konkretne pro tebe ale neni otazka,
kterou ti zodpovi nekdo jiny. Ted, kdyz's vyresil problem s timeouty -
funguje ta karta tak, ze s ohledem na to, v jakem stroji je, postacuje
na to, co se po ni chce ? Pak neznamena.
