5.4.247-neocine-1.1 -- BAIKAL

[feeRnt]

Latest Baikal release for PS4 Linux 5.4.247.

• Features:
  • MediaTek 7668 Driver (mt76x8; MT6632 variant)
  • Blackscreen fix at login and initramfs (WIP)
  • Fixed AMDGPU Gladius Registers (PS4 Pro; greatly improves performance)
  • ZRAM, ZSWAP, ZBUD
  • march, mtune (btver2), -O3 compiler flags
  • Clang/LLVM or GCC-11 builds

Improves on all the previous Baikal releases on this repo.

• Notes:

  Will try to use a 1920x1080 with 60 Hz display mode by default, so make sure your monitor supports this.

  For GPU acceleration, make sure your distribution supplies a Mesa version 25.1 or lower, as newer libdrm is not supported on Linux 5.4. See: Baikal 5.4: no GPU acceleration with newer Mesa/distros.

  If you get blackscreen issues, using a TV instead of a monitor might give better results

  If you switch between monitor sources and lose signal / display, simply press Ctrl+Alt+F2 and then Ctrl+Alt+F7 or Ctrl+Alt+F1 (depends on which TTY your GUI is located in) to regain display.

  ;;; Clang/LLVM version used: LLVM-14, as it seems the most compatible for Kernel 5.4.247 ;;;

what do i need to install with terminal to build from source code im on Kali Linux Debian base

# Firstly, get the build tools:

apt-get update
apt-get install build-essential libssl-dev gcc-11 libgcc-11-dev -y # Need GCC-11 for 5.4.247
apt-get install clang-14 lld-14 llvm-14 -y  # Need LLVM-14 for 5.4.247
apt-get build-dep linux -y

# Then get the firmware:

cd /lib/firmware/mrvl
wget -nc https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/mrvl/sd8897_uapsta.bin
wget -nc https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/mrvl/sd8797_uapsta.bin

mkdir -p /lib/firmware/mediatek
cd /lib/firmware/mediatek
wget -nc https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/mediatek/mt7668pr2h.bin


# Clone the latest release

git clone https://github.com/feeRnt/ps4-linux-12xx --branch 5.4.247-baikal-dfaus --depth=3
cd 5.4.247-baikal-dfaus

# Copy the MediaTek WiFi firmware

if [ -d extra_firmware ]; then

        cp -r extra_firmware/* /lib/firmware

echo "Copying bzImage to $INSTALL_DIR/boot. . ."
cp arch/x86/boot/bzImage "$INSTALL_DIR/boot/"
echo "Copying used .config to $INSTALL_DIR/.config. . ."
cp .config "$INSTALL_DIR/.config"
cd ${INSTALL_DIR}

The bzImage should now be in
boot/, and any modules compiled in lib/ .

I should update the README.
