Config file seems OK to me:
# CONFIG_CPCI690 is not set
CONFIG_PPC_INDIRECT_PCI=y
CONFIG_PCI=y
CONFIG_PCI_DOMAINS=y
CONFIG_PCI_8260=y
# CONFIG_PCI_LEGACY_PROC is not set
# CONFIG_PCI_DEBUG is not set
# CONFIG_NET_PCI is not set
and indirect_pci from arch/powerpc is compiled and used ...
I have tested a bit more. The call trace would be:
[c01db170] m8260_setup_arch
[c01db87c] pq2_find_bridges
[c01dbfa0] pciauto_bus_scan
[c000a754] early_read_config_byte
[c00c8f54] pci_bus_read_config_byte
[c0011424] indirect_read_config
I have done manually, since GDB only reports last two,
and I couldn't get it from log_buf.
(gdb) bt
#0 indirect_read_config (bus=0x0, devfn=3223241436,
offset=8, len=14, val=0x1032)
at arch/powerpc/sysdev/indirect_pci.c:32
#1 0xc00c8fb4 in pci_bus_read_config_byte (bus=0xc01ec2dc,
devfn=8, pos=14, value=0xc01d1f3a "")
at drivers/pci/access.c:52
Now I have check indirect_read_config, and I have seen
the call ends itself, but after that it returns to
pci_bus_read_config_dword
executes some asm and then hangs.
Any idea?
Thanks,
Alex BASTOS
