R: Re: PCI device not working

Hi,

>So its odd that scanning of the second bus didn't report any devices.  Do=
=20
you have code that implements ppc_md.pci_exclude_device ?

not that I'm aware=20
of

>You might also want to put some code in the indirect PCI ops (indirect.c)=
=20
to see what actual values you are getting from various indirect_read_config=
()=20
calls.

To make sure that  ppc_md.pci_exclude_device is not implemented, I've=20
put some printouts inside  indirect_read_config(): I print various paramete=
rs=20
when the function is called, and when it returns and note that:

 1.=20
indirect_read_config() is called 422 times:=20
     174 times for=20
[/pcie@ffe0a000] (controller where the device is not detected)
     248 times=20
for [/pcie@ffe09000]=20
 2. ppc_md.pci_exclude_device is always NULL
 3. the=20
function always returns with PCIBIOS_SUCCESSFUL
 4. the only call to =20
indirect_read_config() inside which  bus_no=3D0x3, returns with the followi=
ng=20
log:

pci_bus 0001:03: scanning bus
-> ind_r_config - [/pcie@ffe0a000]=20
devfn=3D0x0 len=3D0x4 hose->indirect_type=3D0x16 hose->first_busno=3D0x2 bu=

cfg_data=3D0xffffffff len=3D0xff7eb004) val=3D0x4 PCIBIOS_SUCCESSFUL =20

the entire=20
log is about 116Kb and is available in [1] or [2] (didn't feel like pasting=

much data on the ML)
thanx alot,

Davide
