Up to now preferred SLM size was being set to maximum preferred SLM size for GFX 12.5 platforms and to workgroup SLM size for Xe2 but neither of those values are the optimal. The optimal value is: <number of workgroups that can run per subslice> * <workgroup SLM size> Reviewed-by: Lionel Landwerlin <lionel.g.landwerlin@intel.com> Signed-off-by: José Roberto de Souza <jose.souza@intel.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/28910>
