Re: all kernels except i386 MP high cpu in interrupt -- was: 4.2 on H8SSL-I2: acpi at mainbus0 not configured
aarrgh. sorry I ment to post this: Hi, I was asked off-list to gather some more data, which I now present to anyone who's interested. Disclaimer: there is no acute problem to fix, but something is odd. Summary: - the location of a tgz which includes an acpidump and some dmesgs is: http://stuff.ghweb.de/h8ssli2/stuff.tgz - I tested the following kernels on a Supermicro H8SSL-i2 with an Athlon64 X2: amd64: GENERIC, GENERIC.MP, i386: GENERIC, GENERIC.MP - all except the i386/MP kernel have about 70% cpu load on interrupts (the mp kernels on one core), regardless whether acpi is enabled or not on an otherwise idle standard installation (up to 2 ssh-sessions active), and up to 90% interrupt load, if they've got something to do. - the i386/MP kernel has about 0.0% interrupt load, also regardless whether acpi is enabled - I did the following to put some load on I/O: a) ping -f from another machine to this (only 100 MBit-Network), with no packet loss in every case b) dd if=/dev/zero of=/tmp/stuff bs=1m count=2000 - the interrupt count monitored through systat vm 1 is roughly comparatively on all kernels, with and without acpi, except for pciide, which comes short on UP kernels (both count and transfer rate) Some data (interrupt count with systat vm 1): idle: amd64/MPamd64/UPi386/MPi386/UP clock 200 100 200100 ipi 100 rtc 128128 bge05+/-3 5+/-3 5+/-3 5+/-3 a) (ping-f) (clock, ipi and rtc same as above) bge03.4k3.3k3.3k 3.4k +/-100 +/-50 +/-50 +/-50 a) + b) (ping and dd) (clock, ipi and rtc same as above) bge03.4k3.3k3.3k 3.4k +/-100 +/-50 +/-50 +/-50 peaks ofpeaks of up to +2k up to +2k pciide 3.7k850 3.4k 530 +/-150 +/-50 +/-500 +/-20 overall data transfer with dd: amd64/MP: 53-58 MB/s amd64/UP: 11-12 MB/s (about 19MB/s without ping -f) i386/MP: 52-56 MB/s i386/UP: 8- 9 MB/s --knitti

Re: 4.2 on H8SSL-I2: acpi at mainbus0 not configured
Hi, after some sleep and coffee I am embarrassed to realize I made two mistakes: - I didn't provide a GENERIC(.MP) dmesg - I booted off the non-acpi-enabled kernel Sorry for that. Below you can see two GENERIC.MP dmesgs (i386/amd64) which clearly show that acpi is enabled and detected. However, one Problem remains: The interrupt load is very high on GENERIC/amd64 (with and without MP, with and without acpi) - about 70% of one cpu core on the idle machine.

4.2 on H8SSL-I2: acpi at mainbus0 not configured
Hi, thanks a lot to Vim for sending me my new shiny CD set, and to the developers to making this possible. I just installed on a new server (Supermicro H8SSL-I2) and it seems not possible to get ACPI recognized (yes, I did enable it). Unpacking the source from the CD resulted in about 80-90% interrupt load, so I think it would be better for this server having acpi. Has anyone an idea what I could try? dmesg: OpenBSD 4.2 (GENERIC.MP) #1378: Tue Aug 28 10:48:58 MDT 2007 [EMAIL PROTECTED]:/usr/src/sys/arch/amd64/compile/GENERIC.MP real mem = 3220762624 (3071MB) avail mem = 3112398848 (2968MB) mainbus0 at root bios0 at mainbus0: SMBIOS rev. 2.4 @ 0xfbcf0 (50 entries) bios0: vendor American Megatrends Inc. version 080011 date 03/01/2007 bios0: Supermicro H8SSL-I2 acpi at mainbus0 not configured mainbus0: Intel MP Specification (Version 1.4) cpu0 at mainbus0: apid 0 (boot processor) cpu0: AMD Athlon(tm) 64 X2 Dual Core Processor 6000+, 2992.96 MHz cpu0: FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CFLUSH,MMX,FXSR,SSE,SSE2,HTT,SSE3,CX16,NXE,MMXX,FFXSR,LONG,3DNOW2,3DNOW cpu0: 64KB 64b/line 2-way I-cache, 64KB 64b/line 2-way D-cache, 1MB 64b/line 16-way L2 cache cpu0: ITLB 32 4KB entries fully associative, 8 4MB entries fully associative cpu0: DTLB 32 4KB entries fully associative, 8 4MB entries fully associative cpu0: apic clock running at 199MHz cpu1 at mainbus0: apid 1 (application processor) cpu1: AMD Athlon(tm) 64 X2 Dual Core Processor 6000+, 2992.50 MHz cpu1: FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CFLUSH,MMX,FXSR,SSE,SSE2,HTT,SSE3,CX16,NXE,MMXX,FFXSR,LONG,3DNOW2,3DNOW cpu1: 64KB 64b/line 2-way I-cache, 64KB 64b/line 2-way D-cache, 1MB 64b/line 16-way L2 cache cpu1: ITLB 32 4KB entries fully associative, 8 4MB entries fully associative cpu1: DTLB 32 4KB entries fully associative, 8 4MB entries fully associative mpbios: bus 0 is type PCI mpbios: bus 1 is type PCI mpbios: bus 2 is type PCI mpbios: bus 3 is type ISA ioapic0 at mainbus0 apid 2 pa 0xfec0, version 11, 16 pins ioapic1 at mainbus0 apid 3 pa 0xfec01000, version 11, 16 pins ioapic2 at mainbus0 apid 4 pa 0xfec02000, version 11, 16 pins pci0 at mainbus0 bus 0: configuration mode 1 ppb0 at pci0 dev 1 function 0 ServerWorks HT-1000 PCI rev 0x00 pci1 at ppb0 bus 1 ppb1 at pci1 dev 13 function 0 ServerWorks HT-1000 PCIX rev 0xb2 pci2 at ppb1 bus 2 bge0 at pci2 dev 3 function 0 Broadcom BCM5704C rev 0x10, BCM5704 B0 (0x2100): apic 3 int 8 (irq 9), address 00:30:48:5e:6d:f6 brgphy0 at bge0 phy 1: BCM5704 10/100/1000baseT PHY, rev. 0 bge1 at pci2 dev 3 function 1 Broadcom BCM5704C rev 0x10, BCM5704 B0 (0x2100): apic 3 int 9 (irq 5), address 00:30:48:5e:6d:f7 brgphy1 at bge1 phy 1: BCM5704 10/100/1000baseT PHY, rev. 0 pciide0 at pci1 dev 14 function 0 ServerWorks HT-1000 SATA rev 0x00: DMA pciide0: using apic 2 int 11 (irq 11) for native-PCI interrupt pciide0: port 0: device present, speed: 1.5Gb/s wd0 at pciide0 channel 0 drive 0: ST3320620AS wd0: 16-sector PIO, LBA48, 305245MB, 625142448 sectors wd0(pciide0:0:0): using PIO mode 4, Ultra-DMA mode 5 pciide0: port 1: device present, speed: 1.5Gb/s wd1 at pciide0 channel 1 drive 0: ST3320620AS wd1: 16-sector PIO, LBA48, 305245MB, 625142448 sectors wd1(pciide0:1:0): using PIO mode 4, Ultra-DMA mode 5 pciide0: port 2: PHY offline pciide0: port 3: PHY offline pciide1 at pci1 dev 14 function 1 ServerWorks HT-1000 SATA rev 0x00 piixpm0 at pci0 dev 2 function 0 ServerWorks HT-1000 rev 0x00: polling iic0 at piixpm0 iic0: addr 0x2f 00=80 05=ae 06=ff 07=ae 08=ff 09=64 0a=64 0b=5e 0c=73 0d=5c 0e=7b 0f=12 10=b1 11=2e 13=ff 14=22 15=6f 16=d0 17=7b 18=d0 19=cf 1a=bf 1b=0b 1c=21 1d=9c 1e=80 1f=80 20=1c 21=51 22=01 23=0f 25=0f 27=0f 29=0f 2b=0f 3b=ff 3c=ff 3d=ff 3e=ff 3f=ff 40=09 44=40 46=f7 47=ff 48=ff 49=7f 4a=3f 4b=02 4d=7c 50=1e 51=02 52=01 58=80 59=01 5c=03 5e=55 5f=03 60=ca 61=87 62=ca 63=87 64=ff 66=ff 67=ff 68=3f 6a=2b 6b=18 6c=7c 6d=65 6e=e3 6f=b9 70=8a 71=70 72=e5 73=bb 74=e5 75=bb 76=e3 77=b9 78=48 79=43 7a=48 7b=43 7c=48 7d=5f 7e=55 7f=50 80=64 81=5f 82=55 83=50 84=64 85=5f 86=55 87=50 88=46 89=41 8a=55 8b=50 8c=64 8d=5f 8e=55 8f=50 90=07 91=68 92=07 93=68 94=07 95=68 96=07 97=68 98=07 99=68 9a=07 9b=68 9c=07 9d=68 9e=ff 9f=ff a0=ff a1=ff a2=ff a3=ff a4=ff a5=ff a6=ff a7=ff a8=f5 ae=ff af=ff b1=04 b2=30 b3=3f b4=3f b5=30 b6=3f b7=3f b8=3f b9=3f ba=3f bb=89 bc=89 bd=89 be=89 bf=89 c0=89 c1=89 c2=89 c3=01 c4=01 c5=7f c6=ff c9=ff ca=ff cb=ff cc=ff cd=ff ce=ff cf=ff d1=46 d2=46 d3=46 d4=46 d6=f0 d7=ff d8=80 d9=01 da=80 db=01 dc=80 dd=01 de=80 df=01 e0=bb e1=c0 e2=82 e3=ff e4=80 e5=06 e6=fe e7=12 e8=12 e9=12 ea=c8 eb=60 ec=ff ed=ff ee=ff ef=ff f6=60 f7=80 f8=1b fa=ff fd=10 piixpm0: exec: op 1, addr 0x4b, cmdlen 1, len 1, flags 0x08: timeout, status 0x9BUSY,BUSERR pciide2 at pci0 dev 2 function 1 ServerWorks HT-1000 IDE rev 0x00: DMA atapiscsi0 at pciide2 channel 0 drive 1 scsibus0 at atapiscsi0: 2 targets cd0 at scsibus0 targ 0 lun 0: TEAC,
