drm/atomic: add max_size check to drm_property_replace_blob_from_id()

2026-01-14T00:18:31+00:00

The function drm_property_replace_blob_from_id() allows checking whether the blob size is equal to a predefined value. In case of variable-size properties (like the gamma / degamma LUTs) we might want to check for the blob size against the maximum, allowing properties of the size lesser than the max supported by the hardware. Extend the function in order to support such checks.

drm/drm_property: make replace_property_blob_from_id a DRM helper

2023-12-13T20:09:53+00:00

Place it in drm_property where drm_property_replace_blob and drm_property_lookup_blob live. Then we can use the DRM helper for driver-specific KMS properties too. Reviewed-by: Harry Wentland Reviewed-by: Liviu Dudau Signed-off-by: Melissa Wen Acked-by: Maxime Ripard Signed-off-by: Alex Deucher

drm: document drm_property_enum.value for bitfields

2021-07-26T08:08:22+00:00

When a property has the type DRM_MODE_PROP_BITMASK, the value field stores a bitshift, not a bitmask, which can be surprising.

This patch explains the DRM_MODE_PROP_IMMUTABLE flag a bit better by telling which function to call if kernel wants to update drm object's immutable properties.

Revert "drm: Use a flexible array member for blob property data"

2018-03-16T13:44:01+00:00

Using a flexible array for the blob data was a mistake by me. It forces all users of the blob data to cast blob->data to something else. void* is clearly superior so let's go back to the original scheme. Not a clean revert as the code has moved. This reverts commit d63f5e6bf6f2a1573ea39c9937cdf5ab0b3a4b77.
