drm/sysfb: Clear entire framebuffer in atomic_disable

2026-08-31T11:38:53+00:00

drm_sysfb_plane_helper_atomic_disable() previously used plane_state->src_* coordinates to construct the clear rectangle, which depends on user-controlled input. Instead, clear the entire visible framebuffer region using fb_mode dimensions, and use drm_format_info_min_pitch() to compute the safe per-line clear size without touching non-visible bytes at the end of each line.

The is_avivo() function has a logic error where it compares a constant to another constant instead of checking the device parameter: (PCI_VENDOR_ID_ATI_R600 >= 0x9400) Signed-off-by: Shixiong Ou Reviewed-by: Thomas Zimmermann Fixes: f496834e1674 ("drm/ofdrm: Add per-model device function") Signed-off-by: Thomas Zimmermann Cc: # v6.2+ Link: https://patch.msgid.link/20260731111729.703116-1-oushixiong1025@163.com

drm/sysfb: ofdrm: Fix integer overflow in fb_size calculation

2026-08-26T06:50:09+00:00

The framebuffer size calculation `fb_size = linebytes * height` can overflow when both values are large (e.g., 46341 * 46341 > INT_MAX). Since linebytes and height are both int types, the multiplication is performed as int * int, which results in undefined behavior on overflow. Use check_mul_overflow() to detect and prevent this overflow, consistent with the approach used in simpledrm.c and corebootdrm.c.

drm/sysfb: Convert to atomic_create_state

2026-08-21T14:20:24+00:00

drm_sysfb_plane_reset() handles both state creation and teardown of the previous state through the reset hook, which conflates initial state allocation with hardware and software reset at resume. Convert it to drm_sysfb_plane_atomic_create_state(), which only allocates and initializes a pristine state using __drm_gem_shadow_plane_state_init(). Update DRM_SYSFB_PLANE_FUNCS to use .atomic_create_state instead of .reset.
