video: Make CONFIG_FIRMWARE_EDID generally available

2025-06-16T09:00:28+00:00

DRM drivers such as efidrm and vesadrm can export firmware EDID data to userspace. Make the related option CONFIG_FIRMWARE_EDID available without CONFIG_FB. Make it depend on X86, which is currently the only architecture providing EDID information.

fbmon: prevent division by zero in fb_videomode_from_videomode()

2024-03-19T12:20:20+00:00

The expression htotal * vtotal can have a zero value on overflow. It is necessary to prevent division by zero like in fb_var_to_videomode(). Found by Linux Verification Center (linuxtesting.org) with Svace. Signed-off-by: Roman Smirnov Reviewed-by: Sergey Shtylyov Signed-off-by: Helge Deller

video: fbdev: Replace HTTP links with HTTPS ones

2020-07-20T09:47:29+00:00

Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.
