Linux test results

[Vort]

Hello.

After seeing request for Linux testing here, I decided to try it with latest version of Bochs (221cac7).

First attempt was with SliTaz (slitaz-rolling-core64.iso).
After ~30 minutes of unpacking, it requested login and password (strange idea for LiveCD).
But because of default clock settings of Bochs, I was not able to enter login correctly.

Second attempt was with Puppy Linux (fossapup64-9.5.iso).
After ~1 hour of loading black screen appeared and nothing happened within the next 30 minutes.
Probably it failed to switch graphical mode and also failed to notify user about it.

Third attempt was with Tiny Core (TinyCore-current.iso).
It successfully loaded within ~5 minutes:

USB mouse and keyboard was detected correctly and was working correctly:

Looks like this OS variation suits well for USB tests.

I see on screenshot the IPS is ~75M
What is your ips setting in .bochsrc ?
It should be around 50M-150M
The farther you go from true 75M the worse result you supposed to get

I'll try them here later and report

Can you add full download link for SliTaz (slitaz-rolling-core64.iso) and Puppy Linux (fossapup64-9.5.iso) ?

I see on screenshot the IPS is ~75M
What is your ips setting in .bochsrc ?

cpu: count=1:1:1, ips=50000000, quantum=16, model=core2_penryn_t9600, reset_on_triple_fault=1, cpuid_limit_winnt=0, ignore_bad_msrs=1, mwait_is_nop=0, msrs="msrs.def"
clock: sync=slowdown, time0=local, rtc_sync=0

Without slowdown I expect to have problems with keyboard repeating characters very fast.
For example, for failed attempt with SliTaz (without slowdown), there was around 500M IPS at login screen.

Can you add full download link for SliTaz (slitaz-rolling-core64.iso) and Puppy Linux (fossapup64-9.5.iso) ?

Slitaz booted perfectly to GUI within 3-5 minutes. Then I opened terminal and it looked like all good.

With the following CPU setting:

cpu: model=corei7_icelake_u
cpu: count=1, ips=500M, reset_on_triple_fault=1, ignore_bad_msrs=1
cpu: cpuid_limit_winnt=0

I use 2GB memory setting:
memory: guest=2048, host=2048

And my host is Core I7 12900 which is capable to reach 200M-250M IPS natively.

Puppy Linux (fossapup64-9.5.iso): about 10 minutes to boot

I use cirrus graphics in configuration

After rebuilding Bochs with proper optimization, I tried to run SliTaz again.
I configured ips=200000000 and my CPU was able to get 160M IPS during decompression.
With sync=slowdown at login screen IPS was 300M, but I was able to enter login (tux) successfully.
GUI of SliTaz did not loaded however, so I tried to enable cirrus video next time.
After that, GUI loaded, but (USB) mouse cursor was very laggy - movements, which took half second of real time, were executed by OS during 4 seconds.
Similar problems happened with keyboard.
Do not know if I made some mistakes with configuration or it's a sign of problems with Bochs.
Here is a screenshot of loaded OS:

After enabling cirrus video, Puppy Linux loaded successfully.
Also I have found why lags were happening:
I was using chipset=i440bx instead of chipset=i440fx for enabling cirrus video.
