Hi, I have a problem with PCI-PCI bridge on sparc64(sun ultra5) while tesing firewire driver. I have a Adaptec card which has a firewire and a USB2 chips behind PCI-PCI bridge. With this card the DMA trasfer speed is poor and it sometimes causes timeout which leads to panic(*1). I finally found that this is because the PCI-PCI bridge is not configured correctly and setting the cache line size in the bridge by pciconf fixes the problem. (pciconf -w -b pci1:1:0 0x0c 16) Sun's APB PCI-PCI bridges seem to be configured correctly but the one on the card doesn't. Who should configure such bridges? Does upgrading firmware fix the problem? (*1) device reports timeouts while DMA transfer is active and unloading dmamap causes accesss faults. /\ Hidetoshi Shimokawa \/ simokawa@sat.t.u-tokyo.ac.jp PGP public key: http://www.sat.t.u-tokyo.ac.jp/~simokawa/pgp.html output of dmesg and pciconf -lv follows: Copyright (c) 1992-2003 The FreeBSD Project.
