LibreELEC Generic x86_64 with native HDMI 3D on amdgpu (round 20, 2026-09-08)

Development image of LibreELEC Generic x86_64 with native HDMI 3D on amdgpu. Built 2026-09-08 from branch local/frl-72y-3d @ 38fc65a for one machine (Intel NUC with a Radeon RX 7600, HDFury VRROOM, JVC DLA-RS4100). Expect rough edges.

What is in it

• LibreELEC master + kernel 7.2.4 with five amdgpu/drm patches (packages/linux/patches/default/0100-0104): HDMI 1.4 3D modes on HDMI connectors, 3D announced in the HDMI VSIF, frame packing with the doubled timing. The upstream form is the three-patch series on amd-gfx: https://lore.kernel.org/amd-gfx/20260907125015.69811-1-adrian.betschart@cinemaone.ch/
• popcornmix's Kodi branch fix-stereoscopic-3d-gbm-upstream on top of Kodi 22.0b2 (MVC playback, 3D Blu-ray ISO, authored subtitle depth incl. MKV remuxes), and his MVC-capable ffmpeg.

Requirements

• A native HDMI output on the GPU (the connector must show up as card0-HDMI-A-*); a DisplayPort-to-HDMI converter does not work.
• Tested only on the RX 7600 (DCN 3.2.1). Other AMD GPUs are untested.

Settings after first boot

• Whitelist (Settings > System > Display): your 2D modes plus the 1080p24 3D entries, e.g. 0192001080024.00000ptabfrp, 0192001080023.97608ptabfrp, 0192001080024.00000ptab, 0192001080023.97608ptab (the 23.976 identifier must read exactly as the box offers it).
• "Adjust display refresh rate": On start / stop.
• 3D output layout defaults to frame packing; KODI_3D_PREFER=tab|sbs in the Kodi environment or <stereoscopicpreferframepacking>false</stereoscopicpreferframepacking> in advancedsettings.xml changes that.

Files

• *.img.gz: write to a USB stick (LibreELEC USB-SD Creator, dd or Etcher) and boot from it.
• *.tar: update an existing LibreELEC install by copying it to /storage/.update/ and rebooting.
• sha256 files alongside.
