From: Krystian Pradzynski <krystian.pradzynski@linux.intel.com> mainline inclusion from mainline-v6.7-rc1 commit 8ed520ff4682aaaef7d124bd9c0950092fddb9c1 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBID30 CVE: CVE-2024-54193 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i... ------------------------------------- Configure autosuspend values per HW generation and per platform. For non silicon platforms disable autosuspend for now, for silicon reduce it to 10 ms.
