Subject: i/o and memory space enable bits in PCI-PCI bridge
Date: Tue, 07 Dec 2004 22:48:13 +0300 [thread overview]
Message-ID: <41B608FD.7070209@dev.rtsoft.ru> (raw)
Hi!
Can somebody give me a hint: - what part of 2.6 (mips) code is
responsible for setting i/o and memory space enable bits in PCI-PCI
bridge config. space command register?
On my board those bits are not set after bridge is configured.
Currently I'm using the following change in "pcibios_enable_resources"
to work with devices behind the bridge.

+++ arch/mips/pci/pci.c 2004-12-06 18:21:22.000000000 +0300
@@ -164,7 +164,7 @@
pci_read_config_word(dev, PCI_COMMAND, &cmd);
old_cmd = cmd;
- for(idx=0; idx<6; idx++) {
+ for(idx=0; idx<=PCI_BRIDGE_RESOURCES; idx++) {
/* Only set up the requested stuff */
if (!(mask & (1<<idx)))
continue;
but I think there should be some legal way I missed.

Thank you,
