User Zone / Re: Virtual machine to run x86 software on ppc64le a host

« on: February 01, 2020, 10:32:53 pm »

It pretty much works, and many things can be made to work with qemu-user. hqemu is notably faster but less compatible.

Not that I'm aware of, or at least it doesn't seem to make any difference.

Even if you do, there is still a x86 binary-only blob that does the actual extraction. (You should or should not trust me as I may or may not have tried this.) That blob I so far have not gotten running in qemu-user.

For certain devices. This machine is fine with a 5.3 kernel (haven't got around to updating it yet), and the Samsung NVMe SSDs Raptor ships appear to be unaffected.

General CPU Discussion / Re: Ultravisor state and/or FlexVer as a substitute for confidential/trustworthy rem

« on: January 12, 2020, 12:45:10 am »

I'm doing research for a future Talospace article on the ultravisor, but while it should do something conceptually similar I don't think it's an exact replacement for SGX.

Flexver seems to have a little different scope and involves tamper protection as well AIUI, but @madscientist159 could say more about that.

Yes, guest posts are welcome, subject to editing for accuracy and house style. Do note they would be uncompensated (the money I make basically pays the domain name and defrays a sliver of Floodgap's hosting costs), but your writing would remain yours.

And welcome.

Are you on Fedora? fstrim.timer will become default in F32 (hopefully).

When rebooting sometimes restarts without onboard audio available

I haven't observed the lack of onboard audio on reboots, but I usually don't reboot my Blackbird much when it's on. On the other hand, I still occasionally have situations where it won't put video up on HDMI, or at least my home projector won't see it.

VLC sometimes remains "running" after closing out

This is not specific to the Blackbird; I've seen this on the Talos. I haven't figured out why this occurs. A killall -9 will nuke it.

Alternatively, go to the settings and uncheck Allow only one instance. This doesn't solve the problem but it makes it much less annoying, and you can clean up the corpses later.

Large images in GIMP are much slower to work with

I haven't been happy with GIMP on any platform. I use Krita or azpainter.

Some of your other issues sound more software-motivated, but I think that PCIe-NVMe bridge might be a little rickety.

Operating Systems and Porting / Re: Firefox Status

« on: January 04, 2020, 06:22:25 pm »

With those hints I managed to get it working, two main points:
- Clang doesn't compile it right yet, I had to force using gcc/g++
- Not sure about the selection of a different linker, it did not make any apparent difference.

Yes, clang doesn't work properly. It's possible that gold has been fixed, but I'd still stick to GNU ld (bfd).

I opted to fetch apt-get source firefox and build it with an updated mozconfig.in that sets:
export CC=/usr/bin/gcc
export CXX=/usr/bin/g++
Also had to limit threads to 24, I ran out of RAM on 32 threads.

Successfully running mainline firefox installed through a selfmade deb-package.

I just do -j24 for makes myself, but largely because I want a few threads so I can play Descent. How much RAM is in your system? This machine has 32GB.

After all that, what did you do to fix it?

No, Firefox should work and build fine. I haven't done a build against central in a couple weeks, but I'm typing this in Firefox 71 on Fedora 31 on a Talos II, so I know at minimum that mozilla-release works. What does your mozconfig look like? The ones I use are here:

(which uses the same ones as ...)
