Here comes the link: https://github.com/medude/linux/tree/v5.4/topic/kasan-arm.v7 I just applied Arnds Patche which you didn't added into your v7. > > grep KASAN build/linux-custom/.config > > CONFIG_HAVE_ARCH_KASAN=y > > CONFIG_CC_HAS_KASAN_GENERIC=y > > CONFIG_KASAN=y > > CONFIG_KASAN_GENERIC=y > > CONFIG_KASAN_OUTLINE=y > > # CONFIG_KASAN_INLINE is not set > > CONFIG_KASAN_STACK=1 > > CONFIG_TEST_KASAN=m > > My config is: > > CONFIG_HAVE_ARCH_KASAN=y > CONFIG_CC_HAS_KASAN_GENERIC=y > CONFIG_KASAN=y > CONFIG_KASAN_GENERIC=y > CONFIG_KASAN_OUTLINE=y > # CONFIG_KASAN_INLINE is not set > CONFIG_KASAN_STACK=1 > # CONFIG_TEST_KASAN is not set > > > are you using something different by any chance? > > Unfortunately not. With your v7 it is working on my imx6 but unfortunately I can't run my gstreamer testcase. My CPU load goes to 100% after starting gstreamer and nothing happens.. But the test_kasan module works =) So I decided to check a imx6quadplus but this target did not boot.. I used another toolchain for the imx6quadplus gcc-9 instead of gcc-8. So it seems that something went wrong during compilation. Because you didn't changed something within the logic. I wonder why we must not define the CONFIG_KASAN_SHADOW_OFFSET for arm.
