New fedora distro: distrobuilder fedora-http recipe with full GNOME desktop (GDM autologin), the PS5 IW620 internal WiFi modules built from nxp-imx/mwifiex + ps5-linux-mwifiex, and an RPM packaging path for the shared PS5 kernel (docker/kernel-builder-rpm). Notable PS5-specific fix: the kernel patches write into the request_firmware() buffer to skip the firmware signature header (gfx_v10_0_early_init, amdgpu_sdma_init_microcode). Fedora ships firmware xz-compressed, and the kernel maps xz-decompressed firmware read-only (fw_decompress_xz_pages -> fw_map_paged_buf -> vmap PAGE_KERNEL_RO), so the write oopses amdgpu before /dev/dri exists and the display never comes up. Distros with zstd or uncompressed firmware decompress into writable buffers, which is why only Fedora was affected. The recipe therefore ships the cyan_skillfish GPU firmware uncompressed, materializing linux-firmware's dedup symlinks first (unxz refuses symlinks). Also installs umoci/skopeo in the image builder (Fedora 41+ bases ship as OCI archives) and wires fedora into build_image.sh (FORMAT=rpm) and the image-builder entrypoint. Tested on PS5 hardware: GNOME displays over HDMI, internal WiFi scans and connects. [skip ci] Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
