OpenBSD Mentorship
Hello all, There was a BOF for new project members being given at BSDCan tonight that I couldn't make, but I still think that I could benefit from mentorship on the project. I'm wondering if anyone would be open to providing this? One thing that caught my attention was working on OpenBSD storage, ex. ISCSI. If you are experienced in this area, and open to mentoring, please contact me privately. Please seriously consider this if you are a "storage hacker" willing to offer mentorship! Thank you, Katie
Firefox and DPMS
When watching fullscreen videos in Firefox on my OpenBSD desktop, Firefox doesn't inhibit DPMS, allowing the display to turn off. This isn't new for me, since I noticed the same thing back in 2018. At that time, I tested Chromium as well, and it performed as expected by keeping my display on. I've looked into this a couple of times since then, and at this point I'm sure it has nothing to do with OpenBSD. Instead, it seems to be due to the way Firefox attempts to inhibit DPMS and/or the screensaver, which apparently doesn't work with a simple window manager setup like mine. I assume it works fine under XFCE and Gnome. I've worked around this issue by creating keybindings to disable and enable DPMS manually when needed (using xset), so this isn't a high-priority problem for me. However, I was hoping to see if others have experienced the same behavior, if anyone can confirm my assumption about WMs/DEs, and if there's a better way to deal with it.
High sys/spin CPU and hangs on ThinkPad T14 (amdgpu)
I've been running snapshots on my Ryzen ThinkPad T14 for about 1.5 years and everything has been working great except for some occasional hangs which seem to be getting more frequent. I've heard about some amdgpu issues upstream and am not sure if this is related to that or something different. - The same graphical programs are always running: i3, Firefox (usually with at least 1 YouTube video tab playing, possibly more open in the background but not actively playing), and Remmina with one RDP session. - When the issue starts the mouse can still be moved around but it gets more sluggish as time goes on. Within 1-2 minutes the mouse usually stops responding and there is no keyboard response. The longer it sits in this state the less chance it can be recovered without a power cycle. - In the past there was no high CPU usage but there were messages like this in dmesg: [drm] *ERROR* ring sdma0 timeout, signaled seq=68607, emitted seq=68607 - On recent snaps (noticed after upgrading from Mar 25 to May 3) the effect seems to be almost 100% CPU usage (~40% sys/~60% spin) making the whole system sluggish. I haven't seen the drm error recently. - If caught fast enough sometimes I can SSH in from another machine and `pkill firefox` which will take some minutes to complete and eventually things return to normal. Other times pkilling firefox ends up with several zombie processes and does not recover without a power cycle. - Sitting in the bad state long enough (a few minutes) will cause the system to hang, stop responding to ping, stop responding to SSH. - Opening a new Firefox window, trying to play another YouTube video, or loading a heavy javascript site can trigger the issue sometimes but not always. Sometimes things are fine for a few days, other times I'll have to power cycle multiple times per day. - Nothing interesting in /var/log/messages or /var/log/Xorg* at the issue times Below is some info gathered via SSH during the issue. Is there anything else that would be helpful to collect to narrow this down? Thanks in advance for any pointers, -Mark dmesg: OpenBSD 7.3-current (GENERIC.MP) #1184: Tue May 16 15:53:34 MDT 2023 dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP real mem = 7711297536 (7354MB) avail mem = 7457939456 (7112MB) random: good seed from bootblocks mpath0 at root scsibus0 at mpath0: 256 targets mainbus0 at root bios0 at mainbus0: SMBIOS rev. 3.2 @ 0xbf71 (67 entries) bios0: vendor LENOVO version "R1BET73W(1.42 )" date 12/09/2022 bios0: LENOVO 20UD000HUS efi0 at bios0: UEFI 2.7 efi0: Lenovo rev 0x1360 acpi0 at bios0: ACPI 6.3 acpi0: sleep states S0 S4 S5 acpi0: tables DSDT FACP SSDT SSDT SSDT IVRS SSDT SSDT TPM2 SSDT MSDM BATB HPET APIC MCFG SBST WSMT VFCT SSDT CRAT CDIT FPDT SSDT SSDT SSDT SSDT SSDT SSDT SSDT SSDT UEFI SSDT SSDT BGRT acpi0: wakeup devices GPP0(S0) RESA(S3) GPP5(S0) GPP6(S0) GP17(S0) LID_(S4) SLPB(S3) acpitimer0 at acpi0: 3579545 Hz, 32 bits acpihpet0 at acpi0: 14318180 Hz acpimadt0 at acpi0 addr 0xfee0: PC-AT compat cpu0 at mainbus0: apid 0 (boot processor) cpu0: AMD Ryzen 5 PRO 4650U with Radeon Graphics, 2100.00 MHz, 17-60-01 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,PCLMUL,MWAIT,SSSE3,FMA3,CX16,SSE4.1,SSE4.2,MOVBE,POPCNT,AES,XSAVE,AVX,F16C,RDRAND,NXE,MMXX,FFXSR,PAGE1GB,RDTSCP,LONG,LAHF,CMPLEG,SVM,EAPICSP,AMCR8,ABM,SSE4A,MASSE,3DNOWP,OSVW,IBS,SKINIT,TCE,TOPEXT,CPCTR,DBKP,PCTRL3,MWAITX,ITSC,FSGSBASE,BMI1,AVX2,SMEP,BMI2,PQM,RDSEED,ADX,SMAP,CLFLUSHOPT,CLWB,SHA,UMIP,IBPB,IBRS,STIBP,SSBD,XSAVEOPT,XSAVEC,XGETBV1,XSAVES cpu0: 32KB 64b/line 8-way D-cache, 32KB 64b/line 8-way I-cache, 512KB 64b/line 8-way L2 cache, 4MB 64b/line 16-way L3 cache cpu0: smt 0, core 0, package 0 mtrr: Pentium Pro MTRR support, 8 var ranges, 88 fixed ranges cpu0: apic clock running at 100MHz cpu0: mwait min=64, max=64, C-substates=1.1, IBE cpu1 at mainbus0: apid 1 (application processor) cpu1: AMD Ryzen 5 PRO 4650U with Radeon Graphics, 2100.00 MHz, 17-60-01 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,PCLMUL,MWAIT,SSSE3,FMA3,CX16,SSE4.1,SSE4.2,MOVBE,POPCNT,AES,XSAVE,AVX,F16C,RDRAND,NXE,MMXX,FFXSR,PAGE1GB,RDTSCP,LONG,LAHF,CMPLEG,SVM,EAPICSP,AMCR8,ABM,SSE4A,MASSE,3DNOWP,OSVW,IBS,SKINIT,TCE,TOPEXT,CPCTR,DBKP,PCTRL3,MWAITX,ITSC,FSGSBASE,BMI1,AVX2,SMEP,BMI2,PQM,RDSEED,ADX,SMAP,CLFLUSHOPT,CLWB,SHA,UMIP,IBPB,IBRS,STIBP,SSBD,XSAVEOPT,XSAVEC,XGETBV1,XSAVES cpu1: 32KB 64b/line 8-way D-cache, 32KB 64b/line 8-way I-cache, 512KB 64b/line 8-way L2 cache, 4MB 64b/line 16-way L3 cache cpu1: smt 1, core 0, package 0 cpu2 at mainbus0: apid 2 (application processor) cpu2: AMD Ryzen 5 PRO 4650U with Radeon Graphics, 2100.00 MHz, 17-60-01 cpu2:

Don't think your platform is supported: https://www.openbsd.org/plat.html https://www.openbsd.org/macppc.html otherwise let us know, I will install it on mine too ;d) -- Daniele Bonini May 18, 2023 08:39:07 yellowcutterpillow : > Hello! > > I wanted to install OpenBSD on my Macbook Pro 8,1 (Early/Late 2011) > but seem to fail.

Installing OpenBSD on MacbookPro 8,1 (Late/Early 2011)
Hello! I wanted to install OpenBSD on my Macbook Pro 8,1 (Early/Late 2011) but seem to fail. When I boot up install73.img or miniroot73.img, they boot up, but when I actually boot up the ramdisk, bsd or bsd.rd, they stuck up at a message about aicp0 being remapped or something. I would try to diagnose it but I can't since when I boot with -c flag, the cursor glitches, or the keyboard stops working, because I can't type anything. I've set up a QEMU emulation of OpenBSD on my Linux box and it works fine. The reason I did so is because I've sort read that I can configure the kernel using it though I lost the reference, so now I don't have any idea on how I can even turn on the ``verbose`` flag in the kernel. I can't also access ``dmesg,`` so if anyone has any idea, I'd be more than happy for your help. Some info, MBP 8,1 is Intel i5, QUAD CORE, and UEFI. No BIOS options, not sure if it supports CMS. Thank you very much!
