<para>
|
|
This package takes a long time to build because it compiles code
|
|
specific to each individual generation of Intel GPUs and for a
|
|
variety of media codecs.
|
|
</para>
|
|
|
|
<!-- This reduce the size of iHD_drv_video.so from 319M to 157M
|
|
for me. -->
|
|
<!-- It seems ARL depends on MTL. We need to review once an Arrow
|
|
Lake CPU is launched. -->
|
|
<!-- Support for ARL is completely broken, needs to be turned off to
|
|
complete the build -->
|
|
<para>
|
|
If you know the model of your Intel GPU, you can pass the
|
|
<option>-D{GEN{8,9,10,11,12},MTL,ARL}=OFF</option> option to the
|
|
<command>cmake</command> command but leaving the option for your
|
|
GPU out. Note that the <quote>GEN</quote> number here is the
|
|
generation of the GPU, not the CPU. For example, with an Intel
|
|
Core i7-1065G7 CPU shipping a 11th-generation Intel GPU, the
|
|
<option>-D{GEN{8,9,10,12},MTL,ARL}=OFF</option> option can be used
|
|
so the code specific to the other generations of Intel GPUs won't
|
|
be built.

<parameter>-D{MTL,ARL}=OFF</parameter>: As of October 2023,

Meteor Lake and Arrow Lake iGPU support is broken but still

in intel-media. The build fails if support for either iGPU

is turned on. Since both of these have not been officially

released yet, it is safe to turn support for them off.
