I'm trying to compile and run a kernel from the EVL git tree
commit 5ca8de72d28ad03ec59c71bc05b6452abd9376dd (HEAD -> v5.14-evl-rebase,
origin/v5.14-evl-rebase)rum <rpm@xenomai.org>

I'm on an Intel x86 desktop with an i5-10400, nothing unusual, I think.
The kernel compiles and runs fine with EVL/dovetail turned off.
Web browsers crash when I run the kernel with CONFIG_EVL=y.
With CONFIG_EVL=y, the kernel boots, and latmus runs fine:

# ./latmus
warming up on CPU0 (not isolated)...
RTT|  00:00:01  (user, 1000 us period, priority 98, CPU0-noisol)

18.907

I'm not clear on the negative lat mins, but that's not my main concern.

(evl check doesn't print anything.)

when I try to run chromium browser (which is in a snap) on the EVL=y
kernel, it fails with what seem to be apparmor complaints.
(but really I don't know, I'm confused about what's wrong, other apps seem
ok, but I don't run it for long, I am debugging on my main PC, so I prefer
to run a kernel with a working web browser).

Chromium crashes and exits.
Chromium errors look like this in /var/log:

When I run firefox browser, it  won't open pages and the tabs crash though
the firefox window stays present.

Firefox errors look like this on stderr:

###!!! [Parent][RunMessage] Error: Channel error: cannot send/recv

Here are the only differences between the linux kernel .config files (I
think)
I sorted the .configs with LC_ALL=C, deleted comments,
ran /bin/comm -3 .config-without-evl-set .config-with-evl-set
(deleting lines in common to both files)
and changed the tabs in the comm output to "evl-on:" because gmail eats
tabs on input.
So, lines with evl-on are from the CONFIG_EVL=y version, and lines with
spaces are from no CONFIG_EVL (but they are both compiled in the same
git/evl-linux source tree).
It looks like mostly it's turning off XEN hypervisor stuff and turning on
EVL stuff.  I don't get it.
(I'm not sure whether this is enough, but I didn't want to post two full
config files here.)

This is a follow up to a note I posted here a week ago, saying that I was
not able to run a kernel that I compiled from the EVL tree.
(I did not receive a reply.)
To review, I'm running an Intel i5-10400 with Ubuntu Studio distro 20.04.3.

I am able to compile an EVL 5.14.0 kernel, I can configure two versions,
neither version is a full solution.

1) When I compile the kernel with EVL/Dovetail turned off, the Linux boots
and runs normally, though (of course) EVL doesn't run.
2) When I compile the kernel with EVL/Dovetail turned on, Linux boots, and
EVL runs ok, but graphical web browsers crash.

With CONFIG_EVL=y, Firefox, Chromium, and Google Chrome crash or hang.
(I only turn EVL on and off in make nconfig, I don't change other settings.)
There seem to be errors in syslog that say apparmor and snap are getting
upset, apparmor=DENIED, etc.
I can run the /usr/bin/lynx text-based web browser ok, so it's not web
browsing or networking that is the problem.
I think the problem might be with the kernel's interaction with snap and/or
apparmor.
I am not familiar with these subsystems, so I don't know.

I'm looking for advice to fix my problem.
I don't know whether my problem is only in the kernel .config file or
whether I need to reconfigure something else like apparmor or snap.

Related questions:
Are other people running EVL on Ubuntu Studio (or other Ubuntu) on an x86?
Is there a best way to get a .config to start with?
The EVL build-steps mostly assume that it will just work (if you follow the
Caveat).
I made a .config with: make LSMOD=lsmod-output localmodconfig
but I'm not sure that's best.
Noting that I feel like I'm having problems configuring the kernel, I was
hoping to find an existing .config that was better for EVL than the plain
Linux ones.
But I'm not sure whether the problem is in my kernel or elsewhere like
snap/apparmor.

Thanks,
-Andy
