|

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>

133 |
|
---|
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},MTL,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},MTL,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 Xe-HPG
|
---|
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.

166 | XeHPC is not enabled by default but they are some data center GPUs.
