2022-03-21drm/selftest: plane_helper: Put test structures in static storageNathan Chancellor1-4/+4
Clang warns on certain 32-bit architectures: drivers/gpu/drm/selftests/test-drm_plane_helper.c:76:5: warning: stack frame size (1064) exceeds limit (1024) in 'igt_check_plane_state' [-Wframe-larger-than] int igt_check_plane_state(void *ignored) ^ 1 warning generated. The structures in igt_check_plane_state() total 1008 bytes, so any small amount of inlining will cause the stack frame to exceed the 32-bit limit of 1024, triggering the warning. Move these structures to static storage, which dramatically reduces the amount of stack space in igt_check_plane_state(). There is no testing impact, as igt_check_plane_state() is only called once in the driver.

2021-10-22drm/i915/selftests: Properly reset mock object propers for each testDaniel Vetter1-0/+1
I forgot to do this properly in commit 6f11f37459d8f9f74ff1c299c0bedd50b458057a Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Fri Jul 23 10:34:55 2021 +0200 drm/plane: remove drm_helper_get_plane_damage_clips intel-gfx CI didn't spot this because we run each selftest in each own invocations, which means reloading i915.ko. But if you just run all the selftests in one go at boot-up, then it falls apart and eventually we cross over the hardcoded limited of how many properties can be attached to a single object. Fix this by resetting the property count. Nothing else to clean up since it's all static storage anyway.

2021-08-02drm: Fix oops in damage self-tests by mocking damage propertyDaniel Vetter1-216/+71
I've added a new check to make sure that drivers which insepct the damage property have it set up correctly, but somehow missed that this borke the damage selftest in the CI result noise. Fix it up by mocking enough of drm_device and drm_plane so we can call drm_plane_enable_fb_damage_clips() to make the new check happy. Since there's a lot of duplicated mock code already copy-pasted into each test I've also refactored this a bit to trim it down. v2: Squash in fixup from 0day for drivers/gpu/drm/selftests/test-drm_damage_helper.c:15:19: warning: symbol 'mock_device' was not declared.

2020-02-12drm/modes: Make sure to parse valid rotation value from cmdlineStephan Gerhold2-2/+14
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 <stephan@gerhold.net> Signed-off-by: Maxime Ripard <maxime@cerno.tech> Link: https://patchwork.freedesktop.org/patch/msgid/20200117153429.54700-2-stephan@gerhold.net

2019-12-16drm/modes: parse_cmdline: Add support for specifying panel_orientation (v2)Hans de Goede2-0/+23
Sometimes we want to override a connector's panel_orientation from the kernel commandline. Either for testing and for special cases, e.g. a kiosk like setup which uses a TV mounted in portrait mode. Users can already specify a "rotate" option through a video= kernel cmdline option. But that only supports 0/180 degrees (see drm_client_modeset TODO) and only works for in kernel modeset clients, not for userspace kms users. The "panel-orientation" connector property OTOH does support 90/270 degrees as it leaves dealing with the rotation up to userspace and this does work for userspace kms clients (at least those which support this property).

Some options which can be specified on the commandline, such as margin_right=..., margin_left=..., etc. are applied not only to the specified mode, but to all modes. As such it would be nice if the user can simply say e.g. video=HDMI-1:margin_right=14,margin_left=24,margin_bottom=36,margin_top=42 This commit refactors drm_mode_parse_command_line_for_connector() to add support for this, and as a nice side effect also cleans up the function a bit.
