From 4b5a0f8e11d175f0e83c1c3475f271321e74f07b Mon Sep 17 00:00:00 2001 From: Yongqin Liu Date: Wed, 18 Aug 2021 17:42:32 +0800 Subject: suspend_blocker: Use Cuttlefish's workaround to avoid suspending the device Reuse Cuttlefish's suspend blocker service to avoid suspending the device while running CTS tests. This is actuallly a cherry-pick of Amit's change on db845c here: https://android-review.googlesource.com/c/device/linaro/dragonboard/+/1723130 The problem is that "adb shell stop" is causing a PM suspend and subsequent loss of adb connectivity. The problem could also be reproduced by the vts ltp test. Test: booted to homescreen with hikey and hikey960 board, and adb shell stop does not cause suspend any more Signed-off-by: Yongqin Liu Change-Id: I290faa5182135a619c4053d12a88a2d534641d7f --- sepolicy/file_contexts | 1 + sepolicy/suspend_blocker.te | 6 ++++++ 2 files changed, 7 insertions(+) create mode 100644 sepolicy/suspend_blocker.te (limited to 'sepolicy') diff --git a/sepolicy/file_contexts b/sepolicy/file_contexts index 1e712113..9592d82e 100644 --- a/sepolicy/file_contexts +++ b/sepolicy/file_contexts @@ -20,6 +20,7 @@ /(vendor|system/vendor)/bin/uim u:object_r:hci_attach_exec:s0 /(vendor|system/vendor)/bin/hw/android\.hardware\.bluetooth@1\.0-service\.hikey u:object_r:hal_bluetooth_hikey_exec:s0 /(vendor|system/vendor)/bin/nanoapp_cmd u:object_r:nanoapp_cmd_exec:s0 +/(vendor|system/vendor)/bin/suspend_blocker u:object_r:suspend_blocker_exec:s0 /(vendor|system/vendor)/lib(64)?/hw/gralloc\.hikey960\.so u:object_r:same_process_hal_file:s0 /(vendor|system/vendor)/lib(64)?/hw/gralloc\.hikey\.so u:object_r:same_process_hal_file:s0 diff --git a/sepolicy/suspend_blocker.te b/sepolicy/suspend_blocker.te new file mode 100644 index 00000000..fa6e02a8 --- /dev/null +++ b/sepolicy/suspend_blocker.te @@ -0,0 +1,6 @@ +type suspend_blocker, domain; +type suspend_blocker_exec, exec_type, vendor_file_type, file_type; + +init_daemon_domain(suspend_blocker); + +wakelock_use(suspend_blocker); -- cgit v1.2.3
