SMP kernel does not honor boot parameter "noht"
Last modified: 2013-08-05 21:15:13 EDT
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; FreeBSD i386; en-US; rv:1.7.8) Gecko/20050512 Firefox/1.0.4 Description of problem: We have a system with 2 CPUs each of them with HT support. We want to disable the hyper-threading (HT) support on the CPUs in order to prove/discard a theory about a lot of stopped processes (e.g. with status "T") we have on that system. Since we do not have a physical access to the system, we can't disable the HT from the system's BIOS. We want to disable the HT support at kernel level. According to the Documentation/kernel-parameters.txt document, in the kernel source tree, this could be done with the "noht" kernel boot parameter. We rebooted the system with this parameter set, e.g. with append="noht" in the lilo.conf, but when the system got back it was still with 4 logical CPUs recognized, e.g. the HT was not turned off. When we run top or cat /proc/cpuinfo, we still see 4 CPUs -- they should be only 2. The kernel doesn't honour the "noht" parameter! Version-Release number of selected component (if applicable): kernel-smp-2.4.21-32.0.1.EL How reproducible: Always Steps to Reproduce: 1.Set the append in lilo.conf to contain the "noht" parameter, e.g. append="noht" 2.Reboot the system 3.Run top or cat /proc/cpuinfo Actual Results: The system continue to run with HT enabled/recognized on the CPUs. Expected Results: HT support should be turned off, according to the Documentation/kernel-parameters.txt document. Additional info: The actual record in the lilo.conf is the following: image=/boot/vmlinuz-2.4.21-32.0.1.ELsmp label=linux-noht initrd=/boot/initrd-2.4.21-32.0.1.ELsmp.img read-only append="hda=ide-scsi root=LABEL=/ exec-shield=0 noht"
Did you run /sbin/lilo after modifying lilo.conf?
Of course YES :) cat /proc/cmdline auto BOOT_IMAGE=linux-noht ro BOOT_FILE=/boot/vmlinuz-2.4.21-32.0.1.ELsmp hda=ide-scsi root=LABEL=/ exec-shield=0 noht The machine should have HT turned off, but top and cat /proc/cpuinfo chow us 4 CPUs, instead of 2, as has to be.
Does someone work on this bug?
Yes. I am looking into this bug, as well as another RHEL-3 bug. As soon as I get some status, then I will post it.
Thanks, i look forward for a feedback from you.
Reassigning to Jim Paradis who has much greater expertise in this.
Could you post a dmesg log (use dmesg -s 65536 to get everything)? I'd like to see what the system thinks it's doing on startup. RHEL3 for x86 should force ACPI CPU detection OFF when "noht" is specified, falling back to the mptable. Some mptable implementations have one entry per logical processor, others have one entry per physical package or core. I'd like to see what yours is doing...
