HID: Fix regression caused by commit "3a2c2d61" uhid_event function returned 0 in normal case and with below commit polling thread was being exited resulting in user space not able to read the events sent by uhid kernel driver leading to IOT issues with HID devices using the vendor hid usb drivers. Eg: Apple Magic Mouse scroll functionality was not working as for normal functionality of Apple Magic mouse, output report needs to be sent to hid device, which was not being sent with current implemenation. commit 3a2c2d61f4c8769ea9c1615208a6daf2fa162084 Author: Myles Watson <email@example.com> Date: Tue Nov 10 14:35:57 2015 -0800 Retry HID Polling when EINTR is returned While I'm here - use __func__ consistently in btif_hh_poll_event_thread. - remove braces around a single line BUG: 24647083 Change-Id: I80b99ff0d3ba6336f5ab7a517269fdf63df59b37 Signed-off-by: Myles Watson <firstname.lastname@example.org> Change-Id: If1f69c8d024fd7d03e2d79f19b962653fe2dd8b9
Just build AOSP - Fluoride is there by default.
Instructions for Ubuntu, tested on 15.10 with GCC 5.2.1.
sudo apt-get install libevent-dev
sudo apt-get install ninja-build
or download binary from https://github.com/ninja-build/ninja/releases
Get sha1 of current version from here and then download corresponding executable:
wget -O gn http://storage.googleapis.com/chromium-gn/<gn.sha1>
i.e. if sha1 is “3491f6687bd9f19946035700eb84ce3eed18c5fa” (value from 24 Feb 2016) do
wget -O gn http://storage.googleapis.com/chromium-gn/3491f6687bd9f19946035700eb84ce3eed18c5fa
Then make binary executable and put it on your PATH, i.e.:
chmod a+x ./gn sudo mv ./gn /usr/bin
mkdir ~/fluoride cd ~/fluoride git clone https://android.googlesource.com/platform/system/bt
Then fetch third party dependencies:
cd ~/fluoride/bt mkdir third_party cd third_party git clone https://github.com/google/googletest.git git clone https://android.googlesource.com/platform/external/libchrome git clone https://android.googlesource.com/platform/external/modp_b64 git clone https://android.googlesource.com/platform/external/tinyxml2
And third party dependencies of third party dependencies:
cd fluoride/bt/third_party/libchrome/base/third_party mkdir valgrind cd valgrind curl https://chromium.googlesource.com/chromium/src/base/+/master/third_party/valgrind/valgrind.h?format=TEXT | base64 -d > valgrind.h curl https://chromium.googlesource.com/chromium/src/base/+/master/third_party/valgrind/memcheck.h?format=TEXT | base64 -d > memcheck.h
Fluoride currently has dependency on some internal Android projects, which also need to be downloaded. This will be removed in future:
cd ~/fluoride git clone https://android.googlesource.com/platform/system/core git clone https://android.googlesource.com/platform/hardware/libhardware git clone https://android.googlesource.com/platform/system/media
We need to configure some paths to make the build successful. Run:
cd ~/fluoride/bt gn args out/Default
This will prompt you to fill the contents of your “out/Default/args.gn” file. Make it look like below. Replace “/home/job” with path to your home directory, and don't use “~” in build arguments:
# Build arguments go here. Examples: # is_component_build = true # is_debug = false # See "gn args <out_dir> --list" for available build arguments. libhw_include_path = "/home/job/fluoride/libhardware/include" core_include_path = "/home/job/fluoride/core/include" audio_include_path = "/home/job/fluoride/media/audio/include"
Then generate your build files by calling
cd ~/fluoride/bt gn gen out/Default
cd ~/fluoride/bt ninja -C out/Default all
This will build all targets (the shared library, executables, tests, etc) and put them in out/Default. To build an individual target, replace “all” with the target of your choice, e.g.
ninja -C out/Default net_test_osi.
cd ~/fluoride/bt/out/Default LD_LIBRARY_PATH=./ ./bluetoothtbd -create-ipc-socket=fluoride
