Re: Lenovo Thinkpad T14 Gen3 very slow on MP kernel, faster on GENERIC
Hi,
so I rebuild with your patch applied but it is still very slow with the bsd.mp
kernel.
Thanks for you help

Usually a complete shutdown and plugging and unplugging the power gets it to start working as expected. Until then it's dog slow showing now reason why (pretty sure apm shows a normal cpu frequency and there's no interrupt storm). I would not be surprised if that's the same problem reported here. It happens enough to be mildly annoying, but not enough (and it's not my daily driver) that I have dug into it further beyond just the power cycle. Is it kernel state? Bios? /shrug

Re: Lenovo Thinkpad T14 Gen3 very slow on MP kernel, faster on GENERIC
Hi,
Wow ! you're absolutely right ! If I unplug, no lagg anymore.
So the solution should be to apply your patch and rebuild the kernel ?
Thanks a lot !

FWIW I can definitely get mine to throttle when it's busy. And your
CPU uses a fair bit more power than mine (I specifically looked for a
U rather than a P cpu for exactly this reason) so I'd guess might be
easier to hit the throttle.
The OpenBSD kernel tries to set cpu clock speed high when on mains
power, so it might be worth trying unplugged to see if there's any
difference, or disable that thing with this

Lenovo Thinkpad T14 Gen3 very slow on MP kernel, faster on GENERIC
Hello, I'm experiencing big slowdowns on a LENOVO Thinkpad T14 Gen3 when using MP kernel (on 7.3 and 7.4) but strangely not on GENERIC. For example, starting LibreOffice on GENERIC takes 7 seconds but 35 seconds on MP kernel. It's even lagging when typing some text in an editor or a mail. Switching to GENERIC and all is working as expected... Thanks for your help ! Morgan This is my dmesg on both kernels: OpenBSD 7.4 (GENERIC) #1336: Tue Oct 10 08:52:22 MDT 2023 dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC real mem = 34026549248 (32450MB) avail mem = 32975671296 (31448MB) random: good seed from bootblocks mpath0 at root scsibus0 at mpath0: 256 targets mainbus0 at root bios0 at mainbus0: SMBIOS rev. 3.4 @ 0x8f8a3000 (81 entries) bios0: vendor LENOVO version "N3MET16W (1.15 )" date 06/25/2023 bios0: LENOVO 21AHCTO1WW efi0 at bios0: UEFI 2.7 efi0: Lenovo rev 0x1150 acpi0 at bios0: ACPI 6.3 acpi0: sleep states S0 S3 S4 S5 acpi0: tables DSDT FACP SSDT SSDT SSDT SSDT SSDT TPM2 HPET APIC MCFG ECDT SSDT SSDT SSDT SSDT SSDT SSDT LPIT WSMT SSDT DBGP DBG2 NHLT MSDM SSDT BATB DMAR SSDT SSDT SSDT BGRT PHAT UEFI FPDT acpi0: wakeup devices PEG0(S4) PEGP(S4) PEGP(S4) PEG2(S4) PEGP(S4) GLAN(S4) XHCI(S3) XDCI(S4) HDAS(S4) CNVW(S4) RP01(S4) PXSX(S4) RP02(S4) PXSX(S4) RP03(S4) PXSX(S4) [...] acpitimer0 at acpi0: 3579545 Hz, 24 bits acpihpet0 at acpi0: 1920 Hz acpimadt0 at acpi0 addr 0xfee0: PC-AT compat cpu0 at mainbus0: apid 0 (boot processor) cpu0: 12th Gen Intel(R) Core(TM) i7-1260P, 2151.34 MHz, 06-9a-03, patch 042c cpu0: FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CFLUSH,DS,ACPI,MMX,FXSR,SSE, SE2,SS,HTT,TM,PBE,SSE3,PCLMUL,DTES64,MWAIT,DS-CPL,VMX,SMX,EST,TM2,SSSE3,SDBG,FMA3,CX16,xTPR,PDCM,PCI ,SSE4.1,SSE4.2,x2APIC,MOVBE,POPCNT,DEADLINE,AES,XSAVE,AVX,F16C,RDRAND,NXE,PAGE1GB,RDTSCP,LONG,LAHF,A M,3DNOWP,PERF,ITSC,FSGSBASE,TSC_ADJUST,BMI1,AVX2,SMEP,BMI2,ERMS,INVPCID,RDSEED,ADX,SMAP,CLFLUSHOPT,C WB,PT,SHA,UMIP,PKU,WAITPKG,PKS,MD_CLEAR,IBT,IBRS,IBPB,STIBP,L1DF,SSBD,SENSOR,ARAT,IBRS_ALL,SKIP_L1DF ,MDS_NO,IF_PSCHANGE,TAA_NO,MISC_PKG_CT,ENERGY_FILT,DOITM,SBDR_SSDP_N,FBSDP_NO,PSDP_NO,RRSBA,OVERCLOC ,XSAVEOPT,XSAVEC,XGETBV1,XSAVES cpu0: 48KB 64b/line 12-way D-cache, 32KB 64b/line 8-way I-cache, 1MB 64b/line 10-way L2 cache, 18MB 64b/line 12-way L3 cache cpu0: smt 0, core 0, package 0 mtrr: Pentium Pro MTRR support, 10 var ranges, 88 fixed ranges cpu0: apic clock running at 38MHz cpu0: mwait min=64, max=64, C-substates=0.2.0.2.0.1.0.1, IBE cpu at mainbus0: not configured cpu at mainbus0: not configured cpu at mainbus0: not configured cpu at mainbus0: not configured cpu at mainbus0: not configured cpu at mainbus0: not configured cpu at mainbus0: not configured cpu at mainbus0: not configured cpu at mainbus0: not configured cpu at mainbus0: not configured cpu at mainbus0: not configured cpu at mainbus0: not configured cpu at mainbus0: not configured cpu at mainbus0: not configured cpu at mainbus0: not configured ioapic0 at mainbus0: apid 2 pa 0xfec0, version 20, 120 pins acpimcfg0 at acpi0 acpimcfg0: addr 0xc000, bus 0-255 acpiec0 at acpi0 acpiprt0 at acpi0: bus 0 (PC00) acpiprt1 at acpi0: bus 2 (PEG0) acpiprt2 at acpi0: bus -1 (PEG2) acpiprt3 at acpi0: bus -1 (RP01) acpiprt4 at acpi0: bus -1 (RP02) acpiprt5 at acpi0: bus -1 (RP03) acpiprt6 at acpi0: bus -1 (RP04) acpiprt7 at acpi0: bus -1 (RP05) acpiprt8 at acpi0: bus -1 (RP06) acpiprt9 at acpi0: bus -1 (RP07) acpiprt10 at acpi0: bus -1 (RP08) acpiprt11 at acpi0: bus -1 (RP09) acpiprt12 at acpi0: bus -1 (RP10) acpiprt13 at acpi0: bus -1 (RP11) acpiprt14 at acpi0: bus -1 (RP12) acpiprt15 at acpi0: bus -1 (RP13) acpiprt16 at acpi0: bus -1 (RP14) acpiprt17 at acpi0: bus -1 (RP15) acpiprt18 at acpi0: bus -1 (RP16) acpiprt19 at acpi0: bus -1 (RP17) acpiprt20 at acpi0: bus -1 (RP18) acpiprt21 at acpi0: bus -1 (RP19) acpiprt22 at acpi0: bus -1 (RP20) acpiprt23 at acpi0: bus -1 (RP21) acpiprt24 at acpi0: bus -1 (RP22) acpiprt25 at acpi0: bus -1 (RP23) acpiprt26 at acpi0: bus -1 (RP24) acpiprt27 at acpi0: bus -1 (RP25) acpiprt28 at acpi0: bus -1 (RP26) acpiprt29 at acpi0: bus -1 (RP27) acpiprt30 at acpi0: bus -1 (RP28) acpiprt31 at acpi0: bus 32 (TRP0) acpiprt32 at acpi0: bus 80 (TRP2) acpipci0 at acpi0 PC00: 0x 0x0011 0x0001 acpithinkpad0 at acpi0: version 2.0 acpiac0 at acpi0: AC unit online acpibat0 at acpi0: BAT0 model "5B10W51867" serial 18480 type LiP oem "Sunwoda" "LEN0111" at acpi0 not configured "LEN0100" at acpi0 not configured "INTC1046" at acpi0 not configured "INTC1046" at acpi0 not configured "INTC1046" at acpi0 not configured "INTC1046" at acpi0 not configured "LEN0130" at acpi0 not configured "ELAN0676" at acpi0 not configured "ACPI000E" at acpi0 not configured pchgpio0 at acpi0 GPI0 addr 0xfd6e/0x1 0xfd6d/0x1 0xfd6a/0x1 0xfd69/0x1 irq 14, 360 pins acpibtn0 at acpi0: SLPB(wakeup) acpicpu0 at acpi0: C3(200@1048 mwait.1@0x60), C2(350@127 mwait.1@0x21)
