But looking around with Google, it turns out the Altra Ampere PCIe is definitely quirky, see: https://lore.kernel.org/linux-acpi/20200806225525.GA706347@bjorn-Precision-5520/T/ https://github.com/Tencent/TencentOS-kernel/commit/f454797b673c06c0eb1b77be20d8a475ad2fbf6f The first quirk should probably be activated on Antonio's kernel but the second one being a downstream Tencent patch, isn't. Alas, the second quirk comes with a performance hit, see: https://gitlab.freedesktop.org/drm/amd/-/issues/2078 Thanks, Geraldo Nascimento _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
