Firefox on RISCV-64 fails to detect GPU and falls back to software rendering

I have built Firefox for RISCV-64 architecture on Wayland in Ubuntu 22. sudo apt-get update Dependency packages:- sudo apt-get install -y curl libnspr4 libgtk-3-dev python3-dev llvm-14 llvm-dev libnspr4-dev clang libclang-dev libx11-xcb-dev libevent-dev libdbus-glib-1-dev m4 meson ninja-build libssl-dev libxcb-glx0-dev libxkbcommon-dev libgtk-3-dev libxcb-dri2-0-dev libvpx-dev libnss3-dev pip install -U pip pip install -U meson curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh source $HOME/.cargo/env cargo install sccache echo 'export PATH="$HOME/.cargo/bin:$PATH"' >> ~/.bashrc echo 'export RUSTC_WRAPPER="sccache"' >> ~/.bashrc echo 'export SCCACHE_DIR="$HOME/.cache/sccache"' >> ~/.bashrc echo 'export SCCACHE_CACHE_SIZE="10G"' >> ~/.bashrc source ~/.bashrc cargo install cbindgen nodejs(v17.1.0) cairo version upgrade (1.16.0 -> 1.18.4) git clone --branch FIREFOX_139_0_4_RELEASE --single-branch --depth 1 https://github.com/mozilla-firefox/firefox.git cd firefox -> apply the patch related to riscv64 vi mozconfig mk_add_options MOZ_PARALLEL_BUILD=4 ac_add_options --enable-optimize=-O3 ac_add_options --enable-application=browser ac_add_options --with-app-name=firefox ac_add_options --disable-release ac_add_options --enable-hardening ac_add_options --enable-rust-simd ac_add_options --enable-linker=bfd ac_add_options --disable-bootstrap ac_add_options --enable-official-branding ac_add_options --with-branding=browser/branding/official ac_add_options --enable-update-channel=release ac_add_options --with-unsigned-addon-scopes=app,system ac_add_options --allow-addon-sideload ac_add_options --enable-default-toolkit=cairo-gtk3-wayland ac_add_options --with-system-zlib ac_add_options --enable-strip ac_add_options --enable-system-ffi ac_add_options --with-system-libevent ac_add_options --with-system-nspr ac_add_options --disable-updater ac_add_options --disable-tests ac_add_options --enable-alsa ac_add_options --without-wasm-sandboxed-libraries ac_add_options --with-system-libvpx ac_add_options --with-ccache=sccache ac_add_options MOZ_WEBRENDER=1 MOZ_APP_REMOTINGNAME=Firefox export LDFLAGS="$LDFLAGS -L/usr/local/lib/riscv64-linux-gnu -L/usr/local/lib -lcairo -lX11 -lXext -lfreetype -lEGL -lGLESv2" export CFLAGS="$CFLAGS -I/usr/local/include -I/usr/local/include/cairo -I/usr/local/include/freetype2" export MOZ_ACCELERATED=1 export LIBVA_DRIVERS_PATH=/usr/lib/riscv64-linux-gnu/dri sudo chown -R $USER:$USER /home/user/firefox ./mach vendor rust --ignore-modified ./mach build I followed these steps to build my firefox Actual results: However, it is failing to detect my Mesa GPU driver.When I checked the about:support page in Firefox,under the Graphics section, the composition is listed as WebRender(software), the WebGL driver information is missing, and although the GPU is shown as active, no description is provided. Expected results: Firefox Should detect my GPU Mesa driver and Compositing should show Webrender (hardware),WebGL 1 Driver & WebGL 2 Driver information should be correctly listed and GPU details should display correct. Are there any code changes are required for firefox which is purely built on egl backend on wayland platform? and during startup, i am getting the following logs Can someone help me to resolve this issue?
