isotop on FuguIta†

kaw (2020-09-08 (Tue) 14:07:35)

isotop is a script to configure and customize vanilla OpenBSD into ready-to-use desktop environment.

I have modified isotop to be able to run on #FuguIta.

To run isotop.sh on FuguIta after download it, apply this patch isotop-665-fi.sh.diff .
Then run install script as a root.

$ ftp https://framagit.org/3hg/isotop/raw/master/src/isotop.sh
$ patch < isotop-665-fi.sh.diff
# sh isotop.sh

Here's a screenshot of FuguIta configured by isotop.

Boot mode difference†

Fugu (2020-07-19 (Sun) 15:51:32)

Hello Kaw:

Is there a difference in boot mode of OpenBSD and #FuguIta? I have a Dell PC where OpenBSD is very slow without disabling acpimadt whereas #FuguIta has no such problems.

Any guidance will be gratefully received.

Thank you.

• The kernel config of #FuguIta is almost same as GENERIC.
  Differences are as follows:

  So I don't know why it behaves differently.
  
  Since the storage device used is different between regular OpenBSD(internal HDD, SSD...) and FuguIta(DVD, USB Flashdrive, SD card...) there may be something wrong with the built-in disk device.
  
  In any case, I think we need to see what's slowing down regular OpenBSD.
  • disk I/O
  • stray interrupts
  • anything else?

    -- kaw 2020-07-20 (Mon) 12:50:48

• Thank you for the detailed response. It has to do with buggy bios - APIC. Thank you for sharing #FuguIta with us. -- Fugu? 2020-07-21 (Tue) 09:49:27
• With following procedure, you can check whether the internal disk or its corresponding BIOS function causes the problem:
  
  • In internal disk, make a directory named "ISO" at the root of a partition which is FAT, NTFS, Linux ExtFS or OpenBSD FFS.
  • Put a FuguIta's ungziped ISO image into "ISO" directory.
  • Boot FuguIta with LiveDVD or LiveUSB.
  • The internal disk will be listed as follows:

    scanning partitions: cd0a sd0i sd0j
    FuguIta's operating device(s): cd0a sd0i
    Which is FuguIta's operating device? [default: cd0a] -> sd0i  # in case that sd0 is internal disk

  • Select internal device, then continue booting.

If FuguIta runs slow as OpenBSD with this procedure, the problem could lay on internal disk device. -- kaw 2020-07-21 (Tue) 16:28:11

• I had quite a few ideas to test this:
  
  • Chroot install
  • chain load from a different OS
  • install via different system and move hard drive
  • use a different boot manager
  • install #Fuguita and hack via ramdisk

and one other escaping attention now.
To this end, I started reading through the show and list variables in the UKC config and found that #FuguIta has a lot more that get initialized than vanilla OpenBSD. When that did not work out, I once again disabled acpimadt, installed the operating system and waited for it to boot. The scenario now stood at reordering libraries (library_aslr). I let it complete the first time and then disabled the service via rcctl. This made a dramatic impact on reboot.
Presently, after having run sysupgrade (following -current), the performance is acceptable as good as on a ThinkPad.
My speculation is to do with the execute bit. I haven't read the source code to be certain of this but would appreciate your knowledgeable thoughts on it. I will try the above solution if video and browser performance in unacceptable with my continued testing. -- Fugu 2020-07-21 (Tue) 19:37:36

• Summary Update: During upgrade/install, the acpimadt needs to be disabled during runtime only. All things work except for the cpu temperature which is stuck at a very high inordinate value. The only similarity found is when the install medium is flash disk. Fans, hibernate, sleep - power management; userland setup; networking have no problems. Interestingly, #FuguIta also spends some time in kernel reordering but being a ram-mounted filesystem, the time spent is comparatively smaller. This is a two-hard drive machine and OpenBSD live USB is now getting stuck before Install/Upgrade/Interrupt message prompt (custom part of #FuguIta) - seems to be directly correlational to number of partitions. Pressing power option still gives back the prompt. Although the device will not be high workload intensive, lack of temperature monitoring (#FuguIta live also lists the same numbers) is unnerving. -- Fugu 2020-07-22 (Wed) 14:55:26
• Thank you for the detailed information.
  Is vanilla OpenBSD slowing down because the CPU temperature is considered high and the CPU clock frequency is low?
  If let apmd enabled and manually change the CPU clock with the apm command, can you see anything relevant? -- kaw 2020-07-23 (Thu) 12:54:58
• Hello Kaw: What I meant to say is everything works as in a supported machine except the sensor for reading the cpu temperature is broken.
  My guess is that this failure to initialize during boot is what causes the problem. #FuguIta does not display this behavior since the boot process has custom setup at this exact point where OpenBSD seemingly hangs. Just before shell access, there is an info which says XSDT entry 8 is corrupt. Not sure if OpenBSD devs would want this bug report since this is BIOS initiated.
  When I say userland setup, the fans (two of them) scale according to workload. I stress tested by encoding a video and simultaneously running a 4K Blender video. Everything works once the module is disabled during install/upgrade (workaround with sysupgrade -n) - one time activity only.
  I genuinely look forward to seeing you presenting #FuguIta this weekend. The only time I had these issues was with booting lilo on Slackware though FreeBSD works without complaint.
  Best wishes. -- Fugu 2020-07-23 (Thu) 23:05:59
