The packaging situation of firefox-geckodriver on Ubuntu 20.04 is a mess
and leads to broken packages:

  The following packages have unmet dependencies:
   firefox-geckodriver : Depends: firefox (= 116.0.2+build1-0ubuntu0.20.04.1) but 116.0.3+build1-0ubuntu0.20.04.1~mt1 is to be installed
  E: Unable to correct problems, you have held broken packages.

Therefore, use Ubuntu 22.04 where the firefox package includes the
selenium driver so no more version mismatch.

FIX

Avoid using MODPROBE_SMALL=y that breaks the return value of insmod.
Instead of returning the return code of the kernel module init function,
it just returns 1.

FIX

Refactor DynamicKmod.install() to abstract over how the kernel module
makes its way to the target and fix loading of an existing lisa.ko
module.

Also fix module checksum so that Python compuation matches what the
Makefile computes.

FIX

On some distributions /usr/lib/jvm will only contain symlinks that
points outside that directory, therefore we must make sure to follow
the symlinks.

Fold including internal kernel headers required for the in-tree
build into sched_helpers.h. This way including sched_helpers.h will work
on its own in both workflows instead of requiring duplicated defines
wherever it is used.

The $(src) variable contains either the path to the module on its
own in out-of-tree builds or the path relative to $(srctree) in in-tree
builds. Fix the definition of MODULE_SRC to account for that
discrepancy.

Since having build dependencies missing can lead to non-obvious issues,
add the requirement to the documentation.

FEATURE

Add kernel build dependencies (and to --install-all) so that LISA kernel
module build can succeed.

The current order runs a git fetch prior to moving into the repository directory. Fix this by changing the order of commands.

Remove script that has not been used in the past 6 years.

Update subtrees

1. Add a usage example to the section in doc/setup.rst

Because we removed the default value for --module-kernel-path, it may
not be clear to the user what the argument should actually look like.
Add a usage example in the documentation to account for that.

2. Change the default remote from ssh to https

Defaulting to accessing the GitHub repo over ssh is prone to failing if
ssh is not set up on the machine. Https does not have that issue and so
is probably a more reasonable default.

3. Fix an omission in the kernel stub patch

The kernel stub patch still had `lisa-module-git` in the gitignore
where it should be `lisa-git`.

FIX

Allow autodetection of aarch64-none-elf- toolchain.

FIX

Autodetect both arm-none-eabi- and arm-linux-gnueabi for armv7
architecture.

FIX

The ABI (as defined by devlib) is the common currency. The "arch" is
used with different meaning:
* Kbuild ARCH= parameter
* QEMU architecture
* Alpine Linux architecture

Ensure that all uses of "abi" and "arch" are as expected.

FEATURE

Override the install() method for LISAFtraceDynamicKmod to be able to
handle modules built in-tree and kept in the kernel modules directory.

The method will try to load the module using insmod while checking
whether the version the module was built with matches the Lisa checkout.
If the module version doesn't match, the build will fail with an error.
If the module can't be found in the modules directory, it will fall back
to the default way of building the module.

FEATURE

Add a 'checksum_sources' property to KmodSrc.
'checksum' will contain the checksum of all the file names along with
their contents.
'checksum_sources' will only contain the checksum of the actual sources,
excluding the file names and the Makefile.
Extract the common code into a private method _checksum that can
compute both variants depending on the arguments.

FEATURE

Modify the Makefile for the lisa module to distinguish
between in-tree and out-of-tree building. Adjust the
imports and definitions in the source files accordingly.

With this change, the module can now be copy-pasted into
a kernel tree and built with kbuild like any other kernel
module. The default, out-of-tree build method with Lisa
should work unchanged as before.

Update util-linux to version 2.39.1.

Update rt-app dependencies.

FEATURE

Add x86 and ppc64le architectures to lisa-build-asset so we can build
binaries for devlib (like busybox) easily.

Allow updating devlib busybox easily.

FEATURE

If rmmod failed, try -f. This is currently necessary as failure to
initialize some features will make the module init return a non-zero exit
code. This unfortunately requires an rmmod -f to unload.

FIX

Avoid raising an exception when we do not know how to autodetect the
toolchain for a given target ABI, since this is in the normal path of
target connection.

FIX

Handle x86 32bit arch toolchain.

FIX

Pass approriate parameters to devlib to connect to an adb server over IP
instead of trying to build a device string ourselves (which probably
worked in the past but not in recent adb versions).

Ensure that the platform used is Linux, as we do not support other
platforms.

FEATURE

Add a Workload Automation (WA) plugin that loads the LISA kernel module
and enables the appropriate events based on the trace-cmd instrument
configuration.

Make event to feature mapping use fnmatch so that e.g. "lisa__sched*"
will return the list of all matching features.
