Since the bug is in boot, what I instruct you here is just a workround.
This workaround operates directly on the pcie-pci bridge hardware, so it
may reset your machine if operating incorrectly, but I think there
should not have other damages.
I don't know whether 'pcitool' is available in s10u(check with ls
/usr/bin/pcitool), if so, you can do like this:
#rem_drv wpi
#pcitool /pci at 0,0 -d bdf=0.1c.1,config -o 0x20 -s 4 -w 0xd010d010
#pcitool /pci at 0,0 -d bdf=0.1c.1,config -o 4 -s 1 -w 0x46
#add_drv -i '"pciex8086,4222"' wpi
#ifconfig wpi0 plumb
If pcitool is not available, then it is a bit complex, you can use kmdb
with command line login as an alternative,
#mdb -KF
>20::wrpcicfg 0 1c 1 d010d010
>4::rdpcicfg 0 1c 1
100044 -----the output here may be this value
>4::wrpcicfg 0 1c 1 100046 ---make sure the last byte is 46, leaving
other bytes as is.
if wrpcicfg and rdpcicfg are not available, you can us,
>*pci_putl_func::call 0 1c 1 20 d010d010
>*pci_putb_func::call 0 1c 1 4 46
>:c
The main purpose here is to enable the memory forward function in
pcie-pci bridge, for your laptop, write 0xd010d010 in config space
0x20-0x23, write 0x46 in config space 0x4. The <bus id,device
id,function id> of the bridge is <0,1c,1>.
Note:
1. the d010d010 is what I count according to your 'prtconf -v', the
value just work for this laptop.
2. the wpi driver must *not* attach *before* the pcie-pci bridge is
hacked.
Any questions, pls let me know.
