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.

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.

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/

drm/modes: Make sure to parse valid rotation value from cmdline

2020-02-12T17:32:54+00:00

A rotation value should have exactly one rotation angle. At the moment there is no validation for this when parsing video= parameters from the command line. This causes problems later on when we try to combine the command line rotation with the panel orientation. To make sure that we generate a valid rotation value: - Set DRM_MODE_ROTATE_0 by default (if no rotate= option is set) - Validate that there is exactly one rotation angle set (i.e. specifying the rotate= option multiple times is invalid) Signed-off-by: Stephan Gerhold Signed-off-by: Maxime Ripard Link: https://patchwork.freedesktop.org/patch/msgid/20200117153429.54700-2-stephan@gerhold.net
