Subject[2.4][PATCH] Xeon HT - SMT+SMP interrupt balancing
I am a long time Linux user who has observed a behavior in recent 2.4.x 
kernels that I consider undesirable. I have read the FAQ,
'googled'/searched the LKML archives, "lurked" on the list via archives,
and contacted the Maintainer directly prior to posting. Since Marcelo
has announced the freezing of 2.4, I believe this is the appropriate
time/forum to raise this issue. This issue may be related to other
recent threads with similar subjects, but has not been addressed IMHO.


I have found that each kernel in 2.4.[19|20|21|22|23] detects my Dual
(2) Xeon HT CPUs and maps hardware IRQs, but does not distribute
interrupts from the IRQs across the 4 logical CPUs. All interrupts seem
to be handled by CPU0 except for LOC, which is per CPU. In each case, I
have corrected the behavior by applying Ingo's
"linux-2.4.18-irqbalance.patch" which I found in an archive. Thank you,
Ingo, for posting it -- it has been a lifesaver. ;-) I've found that it
now exists by other names in various places.

For example, I have an Intel SR2300 based on an Intel SE7501-WV2 MB with
two Xeon 2.4G (HT) CPUs and E7500 (Plumas) chip set. Booting the
vanilla kernel results in this:

# `cat /proc/interrupts` from 2.4.23 (essentially vanilla)

CPU0 CPU1 CPU2 CPU3
0: 23147 0 0 0 IO-APIC-edge timer
1: 49 0 0 0 IO-APIC-edge keyboard
2: 0 0 0 0 XT-PIC cascade
8: 1 0 0 0 IO-APIC-edge rtc
15: 4 1 0 0 IO-APIC-edge ide1
16: 0 0 0 0 IO-APIC-level usb-uhci
19: 0 0 0 0 IO-APIC-level usb-uhci
24: 247647 0 0 0 IO-APIC-level eth3
27: 6 0 0 0 IO-APIC-level eth2
31: 1509 0 0 0 IO-APIC-level eth0
48: 2663 0 0 0 IO-APIC-level dpti0
NMI: 0 0 0 0
LOC: 22996 22929 22995 22994
ERR: 0
MIS: 0



However, if I use Ingo's irq_balance patch, I get this:

# `cat /proc/interrupts` on 2.4.23 w/ irq-balancing patch

CPU0 CPU1 CPU2 CPU3
0: 67879 87331 67921 86498 IO-APIC-edge timer

It is my understanding that Ingo's patch implements a "Brownian motion"
of the interrupts. While I'm unqualified to comment on the mathematical
theory, I will confirm that I perceive a real improvement in
performance. The CPU activity reported by 'top' definitely shows better
balance across logical CPUs. The dmesg output for both scenarios is
also attached.

I get similar results on all my Dell 2650 servers which have the Server
Works chip set (specs at support.dell.com). Also, there doesn't seem to
be any difference in behavior by selecting/deselecting full/ht/off
ACPI support, if that is relevant. I know that ACPI is used to scan the
tables regardless -- you'll note proper detection and sibling mapping in
both. Furthermore, I note that if I disable HT in BIOS, I can get the
two CPU balancing of interrupts seen on any non-HT SMP box, e.g., dual
PIII on i440GX chip set.

But, as of 2.4.23 Ingo's patch doesn't apply cleanly, so I modified it.
It is attached for your review -- NOTA BENE: it works and I'm running
it in production with moderate to heavy loads, but I don't know if I've
introduced a bug somewhere else. I've only tested it on the hardware
mentioned above.

I have attempted user space alternatives -- irq_balance-0.06 and
smp_affinity via sysctrl. The former seems to "blindly" affine an IRQ
to a single logical CPU, which in my case, puts the timer and eth3 on
CPU0 and it gets "overloaded" while the others are mostly idle. Using a
mask with the latter results in the low number sibling handling the
interrupts and the other sibling doing nothing/little. Specifically, I
use a mask of 0x03 on, say, IRQ 24 in an effort to use logical CPUs 0-1
and only CPU0 shows activity via /proc/interrupts. Likewise, a mask of
0x0C on, say, IRQ 48 in an effort to use logical CPUs 2-3 and only CPU2
shows activity. The perceived performance in both cases is much less
than using the patch.

Also, I noticed that Nitin Kamble had submitted a possible alternative
patch to 2.5. In offline discussion with him, he preferred a discussion
here prior to doing a back port.

I ask that Ingo's, Nitin's, or somebody's work be considered for
inclusion in the 2.4 mainline kernel to address this issue. It doesn't
seem intrusive, it doesn't break anything I can find, and it "fixes"
part of an existing "feature". I'm willing to test what I can or
provide what I can. I don't have the skills to be a kernel programmer,
but I can follow instructions.

Thank you for your time and effort on this issue. Please reply by CC
and post since I am not subscribed. I follow LKML by archive and Kernel
Traffic (thanks - KT).

Ken Beaty
