Subject: [PATCH 00/13] Add arm64/signal initial kselftest support
Date: Thu, 13 Jun 2019 12:13:22 +0100	[thread overview]
Message-ID: <20190613111335.7645-1-cristian.marussi@arm.com> (raw)

Hi

this patch aims to add the initial arch-specific arm64 support to
kselftest starting with signals-related test-cases.
A common internal test-case layout is proposed which then it is
anyway wired-up to the toplevel kselftest Makefile, so that it
should be possible at the end to run it on an arm64 target in the
usual way with KSFT.

~/linux# make TARGETS=arm64 kselftest

Notes:
-----
- further details in the included READMEs

- more tests still to be written (current strategy is going through the related
  Kernel signal-handling code and write a test for each possible and sensible code-path)

- a bit of overlap around KSFT arm64/ Makefiles is expected with this recently
  proposed patch-series:
