The synchronous wakeup interface is available only for the interruptible wakeup. Add it for normal wakeup and use this synchronous wakeup interface to wakeup the userspace daemon. Scheduler can make use of this hint to find a better CPU for the waker task. With this change the performance numbers for compress, decompress and copy use-cases on /sdcard path has improved by ~30%. Use-case details: 1. copy 10000 files of each 4k size into /sdcard path 2. use any File explorer application that has compress/decompress support 3. start compress/decompress and capture the time. ------------------------------------------------- | Default | wakeup support | Improvement/Diff | ------------------------------------------------- | 13.8 sec | 9.9 sec | 3.9 sec (28.26%) | ------------------------------------------------- Co-developed-by: Pavankumar Kondeti <quic_pkondeti@quicinc.com> Signed-off-by: Pradeep P V K <quic_pragalla@quicinc.com> Bug: 216261533 Link: https://lore.kernel.org/lkml/1638780405-38026-1-git-send-email-quic_pragalla@quicinc.com/ Change-Id: I9ac89064e34b1e0605064bf4d2d3a310679cb605 Signed-off-by: Pradeep P V K <quic_pragalla@quicinc.com> Signed-off-by: Alessio Balsini <balsini@google.com> (cherry picked from commit 30d72758dbe0e7fa9992f5d21ee8d23eec27934a) |
