|

| 128 | <para>
|
|---|
| 129 | This package takes a long time to build because it compiles code
|
|---|
| 130 | specific to each individual generation of Intel GPUs and for a
|
|---|
| 131 | variety of media codecs.
|
|---|
| 132 | </para>

|
|---|
| 134 | <!-- This reduce the size of iHD_drv_video.so from 319M to 157M
|
|---|
| 135 | for me. -->
|
|---|
| 136 | <!-- It seems ARL depends on MTL. We need to review once an Arrow
|
|---|
| 137 | Lake CPU is launched. -->
|
|---|
| 138 | <!-- Support for ARL is completely broken, needs to be turned off to
|
|---|
| 139 | complete the build -->
|
|---|
| 140 | <para>
|
|---|
| 141 | If you know the model of your Intel GPU, you can pass the
|
|---|
| 142 | <option>-D{GEN{8,9,11,12},ARL}=OFF</option> option to the
|
|---|
| 143 | <command>cmake</command> command but leaving the option for your
|
|---|
| 144 | GPU out. Note that the <quote>GEN</quote> number here is the
|
|---|
| 145 | generation of the GPU, not the CPU. For example, with an Intel
|
|---|
| 146 | Core i7-1065G7 CPU shipping a 11th-generation Intel GPU, the
|
|---|
| 147 | <option>-D{GEN{8,9,12},ARL}=OFF</option> option can be used
|
|---|
| 148 | so the code specific to the other generations of Intel GPUs won't
|
|---|
| 149 | be built.

| 150 | </para>
|
|---|
| 151 |
|
|---|
| 152 | <para>
|
|---|
| 153 | To determine the model of the Intel GPU, install
|
|---|
| 154 | <xref linkend='pciutils'/> and run
|
|---|
| 155 | <command>lspci -nn | grep -Ei 'VGA|DISPLAY'</command> first.
|
|---|
| 156 | It will output some information about the GPU. If the output
|
|---|
| 157 | contains <literal>Meteor Lake</literal>, the GPU model is
|
|---|
| 158 | <literal>MTL</literal>. Otherwise, follow
|
|---|
| 159 | <ulink url='https://dgpu-docs.intel.com/devices/hardware-table.html'/>
|
|---|
| 160 | to find the entry for your GPU and the model of the GPU should
|
|---|
| 161 | be in the <quote>Architecture</quote> column. The Xe and XeHPG
|
|---|
| 162 | architectures are covered by the <literal>GEN12</literal> model.
|
|---|
| 163 | </para>
|
|---|
| 164 | <!-- TODO: The info about MTL is my best guess, the referred Intel
|

| 165 | page does not contain Meteor Lake GPU PCI devicd ID as at Feb 2024.
