As it belongs to Gen 12 family, it uses the same GTT stolen memory settings like its predecessors - ICL(Gen 11) and TGL(Gen 12). Inherit gen11 and gen 9 quirks for determining base and size of stolen memory. v2: Fix typos in commit message.(Boris Petkov) Bspec: 52055 Bspec: 49589 Bspec: 49636 Cc: Lucas De Marchi Cc: Jani Nikula Cc: Ville Syrjälä Cc: Imre Deak Cc: x86@kernel.org Cc: Ingo Molnar , Cc: Thomas Gleixner , Cc: Borislav Petkov Signed-off-by: Caz Yokoyama Signed-off-by: Aditya Swarup Reviewed-by: Lucas De Marchi Acked-by: Borislav Petkov --- arch/x86/kernel/early-quirks.c | 1 + 1 file changed, 1 insertion(+) diff --git a/arch/x86/kernel/early-quirks.c b/arch/x86/kernel/early-quirks.c index a4b5af03dcc1..6edd1e2ee8af 100644 --- a/arch/x86/kernel/early-quirks.c +++ b/arch/x86/kernel/early-quirks.c @@ -551,6 +551,7 @@ static const struct pci_device_id intel_early_ids[] __initconst = { INTEL_EHL_IDS(&gen11_early_ops), INTEL_TGL_12_IDS(&gen11_early_ops), INTEL_RKL_IDS(&gen11_early_ops), + INTEL_ADLS_IDS(&gen11_early_ops), }; struct resource intel_graphics_stolen_res __ro_after_init = DEFINE_RES_MEM(0, 0);
