[Gelöst]SUSE PCI Latenz:

revealed · 1 Feb. 2007

Hallo

gelöst: Die Installation gibts nicht mehr bei mir /gelöst

edit; Es geht um SUSE 10.2 64 bit auf meinem ASUS P5B also ICH-8 und Jmicron. /edit

Habe mal gerade wieder mein SUSE gestartet und ab und an hängt es beim Hochfahren einige Sekunden fest. Das passiert nicht immer jedoch versuche ich der Sache auf den Grund zu kommen.

Also der Computer reagiert in dem Fall (hängend) für mich so.:

Meine Maus (Razer Copperhead) bekommt dann keinen Saft. Und beim booten hängt das OS einige Sekunden an dieser Stelle; Bei der IDE Erkennung meines Plextor CD Brenners.

<6>ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx

Wenn ich dann den Powerknopf kurz drücke und mit "ESC" und "STRG+ALT+ENTF" nachhelfe dann bootet es weiter jedoch funktioniert die Maus für diesen Bootvorgang dann immer nicht.

Jetzt denke ich mir in meinem BIOS steht der PCI Latency Timer auf "64" und ich würde das gern global überprüfen, ob das auch so angewendet wird. Weil ich vermute, es könnte damit zu tun haben?

Kann mir jemand die Zauberworte sagen oder mich an die entsprechende Dokumentation weiterleiten?

ich hab schon ein bisschen gesucht aber der Link von dem ich mir etwas erhoffe:
http://wiki.tuxbox.org/IDE-Interface
Ist nicht erreichbar.

Hilfe - Danke im Vorraus

und viele Grüsse

Legacy USB? Das mach ich mal wegend er Maus. Aber mit den Latenzen währe trotzdem wichtig wenn jemand irgendetwas vorzuschlagen hätte? /edit

/sbin/setpci -d *:* latency_timer=20

The 2nd line is the one I want to point out because I just learned this trick....this will lower the priority of some of the other PCI cards which might be hogging bus resources, in particular PCI bus controllers, or video cards. If you can, boost the setting of your audio card by finding it using 'lspci -v', and using 'setpci -s xx:xx.x latency_timer=f8', where xx:xx.x is your audio card's pci address given by 'lspci -v'.

cool!

Aber mein Problem:

Die latencys bei lspci -v stehen alle auf "0" ?
Außer der Latency der TV Karte...

Sollte ich da besser die Finger weglassen?

Alle die auf "0" stehen, scheinen (Onboard) zu sein? "ASUS P5B"

Danke nochmal so weit

edit:

Bus: primary=00, secondary=05, subordinate=05, sec-latency=32

^^ Das wird der Haken sein oder?

"....Versuch macht kluch" :mrgreen

give it a try ...

revealed · 1 Feb. 2007

dann müsste ich das so machen?:

setpci -s 00:1e.0 latency_timer=64

(ich trau mich nich

; will das aber versuchen nur nicht das ich was total falsches mach jetz.

)

edit: effekt ist, wenn ich das Kommando ausführe - das sich der Wert nicht ändert.... hmm.. un nu? /edit

Gruss

oc2pus · 1 Feb. 2007

Vorsicht: die Werte sind Hex-Werte

`setpci -d *:* latency_timer=40' sets the latency timer to 64 (40 hexadecimal).

und du musst diesen Befehl als root eingeben.

ansonsten man setpci lesen, dort wird die Syntax genau beschrieben.

revealed · 1 Feb. 2007

ah ok aber ich hab noch etwas ganz anderes gefunden..

bei mir geht beispielsweise die UDMA Konfiguration im Yast2 nicht.

Und in var/log/ steht das drin:

Also UDMA müsste ja prinzipiell passen so.

Ganz komisch ist beispielsweise wenn ich einen

Code:

# hdparm /dev/sdb

/dev/sdb:
 IO_support   =  0 (default 16-bit)
 HDIO_GET_UNMASKINTR failed: Inappropriate ioctl for device
 HDIO_GET_DMA failed: Inappropriate ioctl for device
 HDIO_GET_KEEPSETTINGS failed: Inappropriate ioctl for device
 readonly     =  0 (off)
 readahead    = 256 (on)
 geometry     = 9729/255/63, sectors = 156301488, start = 0

Absetze kommt wieder dieser komische ioctl Fehler, der mich schonmal von meiner TV Karte abgehalten hat.

Ich weiss ja nicht, aber da muss doch irgendwas sein... wenn ich nur wüsste was das ist.

Und zu Legacy USB steht keine Fehlermeldung in /var/log.

Das muss dann an irgend etwas anderem liegen.

64 in hexadecimal wäre "3634"? Und ich hatte das als "systemverwaltungsmodus" abgesetzt. *Müsste so gehen oder? Aber die Latenzen passen ja sowieso wie es aussieht.

ähm schau dir mal an für welche Pattentypen hdparm gedacht ist ...

und /dev/sdb ist was anderes als /dev/hdb .... (SCSI, SATA, IDE, EIDE ...)

d.h. es gibt ein verschiedene "hdparm-Programme".

revealed · 1 Feb. 2007

achso danke ! Mir geht grad ein Licht auf.

Das ist ja eine SATA.

dann hab ich gerade "sdparm /dev/sr1" abgefragt und dort erkennt er auch meine IDE CD-rom.

-Mann is der Crossraid IDE-SATA Controller mix aus Intel und Jmicron verwirrend.

bleistift:

# sdparm /dev/sr1
/dev/sr1: PLEXTOR CD-R PX-W4824A 1.04 [cd/dvd]
Read write error recovery mode page:
AWRE 0 [cha: n, def: 0]

TRACK_M 4 [cha: y, def: 4]

Danke.

Dann is ja alles ok bis auf das mein Rechner ab und an beim Kaltstart mit SUSE 10.2 sich aufhängt und die Maus nicht geht.

Ich kanns leider nicht 100 % reproduzieren. Ich find das total verwirrend.
