staging: ion: remove from the tree

2020-10-26T05:53:09+00:00

The ION android code has long been marked to be removed, now that we
dma-buf support merged into the real part of the kernel.

It was thought that we could wait to remove the ion kernel at a later
time, but as the out-of-tree Android fork of the ion code has diverged
quite a bit, and any Android device using the ion interface uses that
forked version and not this in-tree version, the in-tree copy of the
code is abandonded and not used by anyone.

Combine this abandoned codebase with the need to make changes to it in
order to keep the kernel building properly, which then causes merge
issues when merging those changes into the out-of-tree Android code, and
you end up with two different groups of people (the in-kernel-tree
developers, and the Android kernel developers) who are both annoyed at
the current situation.  Because of this problem, just drop the in-kernel
copy of the ion code now, as it's not used, and is only causing problems
for everyone involved.

Merge tag 'spdx-5.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/spdx

2020-04-03T20:12:26+00:00

Pull SPDX updates from Greg KH:
 "Here are three SPDX patches for 5.7-rc1.

  One fixes up the SPDX tag for a single driver, while the other two go
  through the tree and add SPDX tags for all of the .gitignore files as
  needed.

  Nothing too complex, but you will get a merge conflict with your
  current tree, that should be trivial to handle (one file modified by
  two things, one file deleted.)

  All three of these have been in linux-next for a while, with no
  reported issues other than the merge conflict"

selftests: add headers_install to lib.mk

2018-09-05T14:12:09+00:00

If the kernel headers aren't installed we can't build all the tests.
Add a new make target rule 'khdr' in the file lib.mk to generate the
kernel headers and that gets include for every test-dir Makefile that
includes lib.mk If the testdir in turn have its own sub-dirs the
top_srcdir needs to be set to the linux-rootdir to be able to generate
the kernel headers.

selftests: android: move config up a level

2018-08-27T19:35:57+00:00

'make kselftest-merge' assumes that the config files for the tests are
located under the 'main' test dir, like tools/testing/selftests/android/
and not in a subdir to android.

selftests/android: initialize heap_type to avoid compiling warning

Initialize heap_type to ION_HEAP_TYPE_SYSTEM to avoid "used uninitialized"
compiler warning. heap_type gets used after initialization, this change is
to just keep the compiler happy.

selftests: android: ion: return Kselftest Skip code for skipped tests

2018-05-30T21:21:52+00:00

When ion test is skipped because of unmet dependencies and/or unsupported
configuration, it returns 0 which is treated as a pass by the Kselftest
framework. This leads to false positive result even when the test could
not be run.

Change it to return kselftest skip code when a test gets skipped to
clearly report that the test could not be run.

Kselftest framework SKIP code is 4 and the framework prints appropriate
messages to indicate that the test is skipped.
