<ul>
+ <li>Experimental support for supporting generic devices has been added;
+ specifying <code>gfx9-generic</code>, <code>gfx10-3-generic</code>,
+ or <code>gfx11-generic</code> to
+ <a href="https://gcc.gnu.org/onlinedocs/gcc/AMD-GCN-Options.html";>
+ <code>-march=</code></a> will generate code that can run on all
+ devices of a series. Additionally, the following specific devices
+ are now available, all of which are compatible with a listed generic:
+ <code>gfx902</code>, <code>gfx904</code>, <code>gfx909</code>,
+ <code>gfx90c</code>, <code>gfx1031</code>, <code>gfx1032</code>,
+ <code>gfx1033</code>, <code>gfx1034</code>, <code>gfx1035</code>,
+ <code>gfx1101</code>, <code>gfx1102</code>, <code>gfx1150</code>,
+ and <code>gfx1151</code>. To use any of the listed new devices including
+ the generic ones, GCC has to be configured to build the runtime library
+ for the device. Note that generic support requires a future ROCm (newer
+ than 6.3.2). For details, consult GCC's
+ <a href="https://gcc.gnu.org/install/specific.html#amdgcn-x-amdhsa";>
+ installation notes</a>.</li>
<li>Support for Fiji (gfx803) devices has been removed (this was already
deprecated in GCC 14).</li>
