Description Heather Conway 2004-08-09 21:40:36 UTC

Description of problem:
The initial nstallation of RHEL 3.0 U2 on EM64T (x86_64) servers
report only UP kernel config being loaded.  Even though the server has
2 CPUs, the v2.4.21-15.EL kernel config is being loaded, not the
v2.4.21-15.ELsmp.
The CPUs are being reported twice in /proc/cpuinfo, ie.  if there is 1
CPU, two are reported and if there are 2 CPUs, then four are reported.

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



How reproducible:
Every time.


Steps to Reproduce:
Install RHEL 3.0 x86_64 on any EM64T capable system with either 3.0GHz
or 3.4GHz CPUs.
  
Actual results:
The kernel config reports itself as UP, instead of SMP, even when
multiple CPUs are installed in the host.

Expected results:


Additional info:

Comment 1 Arjan van de Ven 2004-08-09 21:41:52 UTC

the kernel doesn't report UP; for example 
cat /boot/config-`uname -r` | grep SMP
will show SMP.

Comment 2 Heather Conway 2004-08-09 21:48:40 UTC

So the v2.4.21-15.EL kernel will support the SMP and highmem systems
in the same kernel, correct?  Therefore, for both EM64T and for AMD64
systems, only the v2.4.21-15.EL kernel need be selected, not the
v2.4.21-15.ELsmp, correct?
Thanks.

Comment 3 Arjan van de Ven 2004-08-09 21:50:21 UTC

for amd64 we decided to ship 2 kernel binaries, because UP amd64 boxes
do exist while for em64t, due to hyper threading, they don't.

Btw you cannot and should not determine the value of CONFIG_SMP based
on the kernel name.

Got it...thanks.
