Red Hat Bugzilla – Bug 424541
Please build SMBus driver i2c-piix4 as a module in RHEL4.7
Last modified: 2009-06-19 21:53:44 EDT
+++ 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):
Steps to Reproduce:
1. # modinfo i2c-piix4 in RHEL4.6
2. check the config file in /boot/
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.
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/
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
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
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. ;)
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.
monitoring as per BZ#424531.

Please check and fix it, thanks.
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.
