Operating Systems and Porting / Re: Whonix on PPC64el
« on: March 31, 2021, 12:24:45 pm »
Hi All,

I've followed the instructions found on this link https://wiki.raptorcs.com/wiki/Whonix

I've created KVM VMs using Debian 10.7 ISO images but when trying to install non-qubes-whonix-gateway-xfce or non-qubes-whonix-gateway-cli I could not solve dependency issues.

Has anyone succeeded creating these VMs?

I have them working on a x86 machine with the same Fedora33 I use on my Blackbird.

Thanks

Can you post the exact output of the apt command that fails?  This sounds similar to an issue that I reported upstream to Whonix, which was subsequently fixed.

Hey Jeremy, this is the output I got:

claudio@debian10:~$ sudo apt-get install non-qubes-whonix-gateway-xfce

Some packages could not be installed. This may mean that you have

N: Ignoring file 'patrick.asc' in directory '/etc/apt/sources.list.d/' as it has an invalid filename extension
E: Unable to correct problems, you have held broken packages.

The VM where I've issued this command was created with debian-10.9.0-ppc64el-xfce-CD-1.iso.

Any ideas?

Interesting.  Definitely resembles my recollection of the bug that I got fixed a while back.  I'll see if I can find time to look at this soon, hopefully this weekend.  (Alas, this is not covered by my dayjob, so won't be able to look at it immediately.)

Cheers!

On Debian, 1920x1200 support for the Talos II's AST2500 was broken between Linux 5.5.0-2 and Linux 5.6.0-1.  My suspicion is that the breakage is because of Linux commit 9253f830c9166bfa6cc07d5ed59e174e9d5ec6ca.  This commit added a VRAM size check to the ast driver, which considers double-buffering as mandatory.  1920x1080 resolution at 4 bytes per pixel with 2 buffers is 16.6 MB, while bumping that to 1920x1200 results in 18.4 MB.  According to "lspci -v -s 0005:02:00.0", The Talos II's VRAM size is 16 MiB == 16.8 MB, which explains why 1920x1200 no longer works.

I asked on IRC, and dormito pointed out that the AST2500 supports both 16 MiB and 64 MiB VRAM size, and that in both cases, the VRAM is stolen from the BMC's RAM (512 MiB total).  The default configuration is controlled by a hardware pin (no idea why Raptor picked 16 MiB), but dormito thinks it may be possible to reconfigure the AST2500's VRAM size by writing to a register on the BMC (before the host boots).

In the meantime it definitely seems like a Linux bug should be filed about this, since single-buffered 1920x1200 used to work fine but no longer does.
