I moved this discussion to -hackers, as suggested. I tried -hardware,
but, no response.
I have an ASUS A7N266-E motherboard with the nVidia nForce IGP-128
Northbridge chip, nVidia nForce MCP Southbridge chip, and AMD XP 1800.
# uname -a

root@asus:/usr/src/sys/compile/ASUS i386
The nVidia chip is not supported. I want to access the SMBus to add
some devices.
Of course, ASUS and nVidia will not provide the information necessary
to do this easily!
I have attached the output of pciconf -lv and dmesg w/ bootverbose.
From a previos discussion, the smbus drivers provide the smbus
attached to one of several busses, iicsmb, bti2c, intsmb, alsmb,
ichsmb, amdsmb, or viapropm.
The nearest one to my motherboard is:
pci---amdpm---amdsmb---smbus---smb
The nVidia chip is similar to the definitions in sys/pci/pcireg.h and
from lm-sensors, rumored to be similar to the AMD-758 chipset.
I tried patching sys/pci/amdpm.c to recognize the nVidia chip. No
glory. The maps are at 0x10. Amdpm.c uses a map from 0x58 for the
power management stuff. I guess, see below, the proper map is at
0x18.
# pciconf -r pci0:1:1 0x00:0xff
0x01b410de 0x00b00001 0x0c0500c1 0x00800000
0x00005001 0x00005501 0x00005101 0x00000000
0x00000000 0x00000000 0x00000000 0x0c111043
0x00000000 0x00000044 0x00000000 0x01030105
0x0c111043 0xc0020001 0x00000000 0x00000000
0x00000000 0x00000000 0x00000000 0x00000000
...
0x00000000 0x00000000 0x00000000 0x00000000
The chip has 3 map registers containing 0x00005001, 0x00005501, and
0x00005101, respectively. These are map pointers. I assume these are
physical addresses? How do I determine the block sizes? What is in
these memory blocks?
I cobbled together a kld from amdpm, smbus, etc. Loading it produced
some information. But, I could not unload it and it did nothing...
Also, the 0x5500 memory block was duplicated by some of the underlying
code... One line from the console:
SMBus0: <NVidia nForce Power Management Controller> port
0x5500-0x550f,0x5100-0x511f,0x5500-0x550f,0x5000-0x500f irq 5
at device 1.1 on pci0
I think the blocks are 5000:501f, 5500:550f, and 5100:511f. From
sizes, I think the 5100:511f block is power management. If so, I can
guess at some of the definitions.
The PCIR_HEADERTYPE is 0x80. What is PCIM_MFDEV? Modified Device?
The header appears to be a type 0 with PCIR_SUBVEND_2 and
PCIR_SUBDEV_2 from the type 2 header.
PCIR_CAP_PTR is the start of the capaility list, the the only
capability lword being 0xc0020001. Where do I get the definition of
this lword?
