= Building Linux 7.2.2 with AMDGPU Interlaced Support (RX 6600 XT / DCN)

This guide applies '''only''' the necessary patch for interlaced modes on modern AMDGPU (DCN2/DCN3/DCN4), such as the RX 6600 XT.

== 1. Download Kernel Source ==

<source lang="bash">
cd ~
wget https://cdn.kernel.org/pub/linux/kernel/v7.x/linux-7.2.2.tar.xz
tar -xf linux-7.2.2.tar.xz
cd linux-7.2.2
</source>

== 2. Download the Interlaced Patch ==

<source lang="bash">
wget https://raw.githubusercontent.com/D0023R/linux_kernel_15khz/master/linux-7.2/03_linux_15khz_dcn1_dcn2_dcn3_dcn4_interlaced_mode_fix.patch
</source>

== 3. Apply the Patch ==

<source lang="bash">
patch -p1 < 03_linux_15khz_dcn1_dcn2_dcn3_dcn4_interlaced_mode_fix.patch
</source>

== 4. Configure the Kernel ==

<source lang="bash">
cp /boot/config-$(uname -r) .config
make olddefconfig
</source>

(Optional) Add a custom version string:

<source lang="bash">
scripts/config --set-str LOCALVERSION "-interlace"
</source>

== 5. Build ==

<source lang="bash">
make -j$(nproc)
</source>

Or create Debian packages:

<source lang="bash">
make -j$(nproc) bindeb-pkg
</source>

== 6. Install ==

<source lang="bash">
sudo make modules_install
sudo make install
</source>

Or with packages:

<source lang="bash">
sudo dpkg -i ../linux-image-*.deb ../linux-headers-*.deb
</source>

Update bootloader:

<source lang="bash">
sudo update-initramfs -u
sudo update-grub
</source>

Reboot and select the new kernel.

== Notes ==

* This patch enables <code>interlace_allowed</code> on AMDGPU DCN connectors and removes the temporary interlacing block.
* No 15 kHz / low-dotclock modes are added.
* After reboot, test interlaced modes with <code>xrandr</code> or your preferred tool.
