Description Shane Huang 2007-12-13 20:04:17 EST
+++ This bug was initially created as a clone of Bug #424531 +++

Description of problem:
RHEL4.6 did not build i2c-piix4 into the kernel or as a module,
although the driver patch of AMD SBX00 SMBus has been added into source.
Would you please modify your config file and build i2c-piix4
as a module? So that our customer need not build the kernel source
by themselves if they need the SMBus driver. They only need to load
the driver module.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. # modinfo i2c-piix4 in RHEL4.6
2. check the config file in /boot/

Actual results:
1. No such module i2c-piix4 can be found in RHEL4.6
2. If you check the config file in the /boot/, you will find
that CONFIG_I2C_PIIX4 is not set.

Expected results:
1. i2c-piix4 and the description should be found when run "modinfo i2c-piix4"
2. CONFIG_I2C_PIIX4=m should be found in the config file in /boot/

Additional info:
I need not provide any patch here, what you need do is to re-configure
the config file with "make menuconfig" or some commands else, and select
the CONFIG_I2C_PIIX4 as a module, and provide it in RHEL4.7
Comment 1 Shane Huang 2007-12-19 20:57:19 EST
I checked the kernel config of RHEL4.5 again, confirmed that CONFIG_I2C_PIIX4
has been built as module in x86. But kernels for x86_64 has not built it.

Can you build it too under x86_64? Is there any problem which make you disable 

Comment 2 Bhavna Sarathy 2007-12-20 10:29:11 EST
Yes, this is done and submitted to RH in the nick of time as yesterday was the
code cut off date.  It's a simple config change for plain x86_64, debug and xen
kernels.  I'll let your team handle the testing. ;)
Comment 3 Bhavna Sarathy 2007-12-20 10:31:09 EST
Sorry, my comment pertained to R5.2, ignore but agree should be done for R4.7.  
R4.7 as I recall has a !64BIT from a prvious issue with 64-bit kernels with no
longer exist.  Removing this condition and providing configs would help get this in.
Comment 4 Don Domingo 2008-02-12 21:44:29 EST
monitoring as per BZ#424531.

This issue has not been fixed in the up to date

Please check and fix it, thanks.
Comment 8 Prarit Bhargava 2008-03-12 10:52:25 EDT
Remove !64BIT from i2c-piix4 driver so that it will build as a module in

Seems safe to do given upstream's removal of the same flag -- at one point
i2c-piix4 didn't appear on 64-bit systems and when it did eventually show up
on 64-bit systems upstream removed the flag.
