drm/selftests/test-drm_mm: Mark 'hole_end' as always_unused

2020-11-17T19:05:05+00:00

In the macro drm_mm_for_each_hole() 'hole_end' is provided as a container for 'hole_start + pos->hole_size', but is not utilised in this use-case. We cannot simply delete the variable, so here we tell the compiler that we're intentionally discarding the read value. Fixes the following W=1 kernel build warning(s): drivers/gpu/drm/selftests/test-drm_mm.c: In function ‘assert_no_holes’: drivers/gpu/drm/selftests/test-drm_mm.c:57:18: warning: variable ‘hole_end’ set but not used [-Wunused-but-set-variable] Cc: David Airlie Cc: Daniel Vetter Cc: "Christian König" Cc: Nirmoy Das Cc: dri-devel@lists.freedesktop.org Signed-off-by: Lee Jones Signed-off-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20201116174112.1833368-28-lee.jones@linaro.org

drm/mm/selftests: fix wrong return type casting

2020-06-23T13:57:30+00:00

Function prepare_igt_frag() and get_insert_time() were casting signed value to unsigned value before returning error. So error check in igt_frag() would not work with unsigned return value from get_insert_time() compared against negative value. Addresses-Coverity: ("Unsigned compared against 0, no effect") Signed-off-by: Nirmoy Das Reported-by: Colin Ian King Reviewed-by: Christian König Signed-off-by: Christian König Link: https://patchwork.freedesktop.org/patch/370636/

drm/mm: add ig_frag selftest

2020-06-08T13:14:16+00:00

This patch introduces fragmentation in the address range and measures time taken by 10k and 20k insertions. ig_frag() will fail if the time taken by 20k insertions takes more than 4 times of 10k insertions as we know that insertions should at most scale quadratically. v2: introduce fragmentation by freeing every other node. only test bottom-up and top-down for now. v3: fix incorrect mode check Signed-off-by: Nirmoy Das Reviewed-by: Christian König Signed-off-by: Christian König Link: https://patchwork.freedesktop.org/patch/369076/

In preparation for rearranging the booleans into a flags field, ensure all the current users are using the inline helpers and not directly accessing the members.
