Using MMCONFIG for PCI config space access is simply an

there's no need for KERN_ERR level message. This patch makes the
message a KERN_INFO instead to reduce some of the noise in a kernel
boot with the 'quiet' option. (Note that this has no effect on a
normal boot, which is ridiculously verbose these days.)
this is wrong, please leave this loud complaint in...
So the issues as I understand them:
o some BIOSes are broken and don't properly map MCFG space (though
according to Petr V. reserving MCFG space in e820 is optional, so
the test may be slightly wrong as-is)
it's optional but it's the best test we have for "is the bios total
crap" ;(
o MCFG space is required for (many) PCIe devices (any regular PCI
devices?)
it's not required for *many* (it can't be, windows XP doesn't use MCFG),
but it's required for some of the advanced PCI-E features
o often, there's nothing the user can do to address the points above
other than complain to the vendor.
So where does that leave us? I've got what I consider to be a stupid
error message in my log.
contact your bios vendor.
My system behavior isn't affected in any way
(at least that I can tell), yet I get a loud complaint at boot time.
I guess I just have to live with it?
We really really should complain about bios issues. If only to make sure
vendors who do pay attention to linux have a chance of finding and
fixing them (and via the firmware kit, several big vendors pay attention
early on nowadays)
Hi Arjan,
Do you have a list of E-Mail addresses for the people we should be
complaining to. I have an
Asus VBI laptop that spews all kinds of error messages when I boot the
firmware test kit cd, but
I have no idea who to complain to about this, ASUS? Intel? Heck Intel
puts out the test kit, if they
are going to say it is VBI why don't the make the vendors do the bios
correctly?
Regards,
Steve
