Whether to support android 8(Android Oreo)?
Hi,
Whether to support android 8(Android Oreo)?
HWComposer test fails with PowerVR GPU
Hello! :)
I've spent quite a lot of time trying to get my phone's graphics work with Halium. Vibration and LEDs are fine, and the system is overall stable, but graphics is something I wouldn't mind :)
When I launch the test, it prints correct screen resolution, ((null)) OpenGL ES 2.0 version string, clears the screen and hangs.
The phone (ASUS ZenFone 5) comes with a PowerVR SGX 544MP GPU from Imagination Technologies (test_egl_configs output attached). With a previous libhybris version, the test was blaming undefined symbols, but with the latest version those messages are gone (seemingly this commit: d5183fe). Not sure if it means they are found now...
The kernel and the blobs I use are also used in a LineageOS build for this phone; graphics works there.
I contacted PowerVR, and they seemed quite friendly, but both of us just do not know what direction to research, so I feel libhybris is the best place for this report.
I also attach logcat output, dmesg, a complete strace of the running test and libhybris n linker's debug messages. Messages that I believe are relevant have drm, libEGL, IMGSRV and hwcomposer in them.

Please start tagging versions
Hybris implementations cannot track an unversioned project easily. E.g. mer-hybris has been tagging versions without having a reference upstream: https://github.com/mer-hybris/libhybris/releases
When you do tag the first time, would be much appreciated if it's 0.0.6 ^^
Compiling single library?
Is it possible to use libhybris for using a single library?
I have got GLES for android, is possible to make a libGles.so working on ubuntu without recompiling all the other ubuntu libraries?

Commenting out test_gps from hybris/tests/Makefile.am helps, and everything compiles nicely.

Should dlerror return NULL if no errors
According standard libc, dlerror should return NULL if no errors have occurred;
Bug libhybris hooked dlerror always returns a char buffer.
This may lead to possible failure if dlerror is used to check error in bionic.
Q: Virtualized kernel for vendor blobs to allow free kernel version upgrades?
I am not sure if this is the right place to ask this question, but after realising yet again that my device had too old a kernel for what I wanted, I got the idea of using a VM to enable two separate kernels running. One stripped down minimum memory kernel for the binary blobs from various HW vendors and one kernel for the main OS that can be freely upgraded. Not sure which should be host and which should be guest, both directions could be done, but I guess some sort of HW pass-through would be required regardless.
Is this doable, or am I completely off base?
exit mali-hist-dump thread problem
I am now running libribris on ubuntu andriod graphics library, in libhybris implementation, because the thread mali-hist-dump will cause a process error, so I quit the thread mali-hist-dump to solve this problem, which may Performance is affected, the thread mali-hist-dump in the library what role?
If I do not exit the thread mali-hist-dump, by tracking the PC address, the program is found in the function malioc_release_outputs segment error, there are other ways to solve this problem?

Want to create custom audio effect in native c/c++ for android
I am working on project which deals with audio video playback in Android KitKat. I am able to play video using video view and it's MediaPlayer helps to modify the audio track of video. I know about Playbackparams which can be used for pitch and tempo shifting but it's available from API 23.
I heard about a library called Sound touch which can be used for pitch and tempo pitching but the source code available for the same shows that it works for WAV files.
I am interested in using sound touch library as a audio effect library which I can place in Android's /system/etc/audio_effects.conf and place the SO file in /system/lib.
But I don't know how to turn this sound touch library in order to make it read audio from Android MediaPlayer as I am planning to call this library in the same as we use presetreverb/equalizer?
Kindly help me out if anyone has done such an implementation.
I get EGL_NOT_INITIALIZED when calling eglChooseConfig(...) in test_egl and test_glesv2
Hi, there!
I compiled the latest libhybris version using these android headers http://ubuntuone.com/6PwRhU0CN1MZFrBUNJFnHL and using this /system folder http://ubuntuone.com/64JdjdWVq9F2E5p6gMQE1J (both files are .tar.xz archives). When I run test_egl or test_glesv2 I get assertion errors at test_egl.c:51 or test_glesv2:112. In both cases I do get EGL_NOT_INITIALIZED (0x3001) instead of EGL_SUCCESS (0x3000) after calling eglChoseConfig.
I'm using EGL_PLATFORM=fbdev, have read and write access to /dev/ump (and modules ump and disp_ump are loaded).
My distribution is Arch Linux (armv7 with hard float, kernel version is 3.0.57) running on a Cubieboard.
Has anyone an idea what went wrong?
Thanks for your help!
Regards,
maribu

undefined symbol: eglLockSurfaceKHR
As I can see, the symbol is successfully located:
FOUND eglLockSurfaceKHR in /system/lib/libEGL.so (0x124b0) 291
But after some time (log lines 19190 - 458417) the search continues, to print that undefined symbol message in the end.
So I wonder if the symbol is properly located and used, and what makes the search restart after successfull lookup. Same applies to some other symbols as well.
LD_SHIM_LIBS is not parsed as expected
libhybris/hybris/common/n/linker.cpp
Line 1311 in 4a7d95b
This function searches for complete matches of " :", not ' ' or ':' as stated.
As a result, pairs are not extracted, and shim libs are not parsed.

Seems to be a bug in libhybris.
pthread counter
the pthread counter implementation has one problem, there are a lot of functions which are called *android*pthread* which should be relatively safe to leave unhooked and there are internal functions in the blobs which also have pthread in their name, like osal_cs_init(pthread_mutex_t*) or _Z12osal_cs_initP15pthread_mutex_t when mangled.
- it is possible to add
|| strstr(symbol, "osal") != NULLand|| strstr(symbol, "android") != NULLto https://github.com/libhybris/libhybris/blob/master/hybris/common/hooks.c#L1687 - or which i think is the better solution: replace the
strstrin https://github.com/libhybris/libhybris/blob/master/hybris/common/hooks.c#L1684 withstrncmp(sym, "pthread", 7) == 0 || strncmp(sym, "__pthread", 9) == 0
which solution should be picked or is there an even better one?
here is an example of a crash due to such a function:

hybris breaks on Android M
Breaks on Android M, tested with Nexus 5. Linker has been changed.
wish: README
It would be helpful to have a README file at top level introducing the project.
I found a README file here, but it is completely empty.
https://github.com/libhybris/libhybris/blob/master/hybris/README
Will hybris_alloc_init_mutex cause memory leak?
In my_pthread_mutex_lock:
if (value <= ANDROID_TOP_ADDR_VALUE_MUTEX) {
realmutex = hybris_alloc_init_mutex(value);
...
}
But the malloced memory is not freed when unlock,
will this cause memory leak?
hwcomposer bug?
It seems newer versions of msm hwcomposer have a bug: https://android.googlesource.com/platform/hardware/qcom/display/+/60d8ef4548bfafa3795ac71fdedac7e5173f843e/msm8996/sdm/libs/core/fb/hw_device.cpp#453
This sync_handle is never referenced anywhere else in the code and it is never closed either.
In android they "solve" this by weird commits increasing the amount of allowed open fds it seems.
In surfaceflinger this will probably eventually cause tearing once enough fds have been leaked, because failed dup()'s are not checked for their return values. In lipstick it is more severe since we abort() as soon as we cannot open any files anymore.
Can somebody confirm that this is a bug in hwc?
I propose the following workaround for now/existing blobs until this is fixed upstream:

dlopen() a library that links to libGLESv2 crashes on first call from library to a GLES function
If you dlopen() a library that links to libGLESv2, the first call from that library to the libGLESv2 will segfault on an ifunc. (My particular case was glCreateShader). One workaround is to LD_PRELOAD the glesv2 library.
PLATFORM_VERSION optimization
extract-headers.sh extracts PLATFORM_VERSION parameter from Android's version_defaults.mk. So libhybris uses costructions like #if (ANDROID_VERSION_MAJOR == 4 && ANDROID_VERSION_MINOR >= 1) || (ANDROID_VERSION_MAJOR >= 5) to use correct constructions right to current android source. But it can be optimized to #if ANDROID_VERSION > 17 if script would extract PLATFORM_SDK_VERSION instead of PLATFORM_VERSION.
Bionic patch for lollipop ( 5.0.0 )?
Is it just me or is there no Bionic patch for lollipop?
Also, would this kernel boot up Android after patching Bionic? or do we just need to compile it to get the system directory?
My goal is to access the PowerVR Rogue gpu drivers in the Asus Zenfone 2 from an Arch x86_64 chroot.
compiling libhybris error with arch=x86
Hello,
I want to run libhybris on my x86 device. However after I ran "./autogen.sh --prefix=$HOME/hybris_rootfs --with-android-headers=$ANDROID_HEADERS --enable-arch=x86 --enable-wayland" and "make", I got the following error:
dlfcn.c:203:7: error: initializer element is not constant
st_value: (Elf32_Addr) &android_dlopen,
^
It seems the C99 spec doesn't allow initializing a global varible with a non constant value.
I'm confused as it seems I'm the only person who met such problem. I can't find the solution anywhere through the internet. Or maybe this issue is too simple to be an issue. But with my limited compiler knowledge, I can't figure out the way to walk around it.
Please Help!!! @stskeeps
Segmentation fault when printing a float
EDIT: This issue seems to be present in a bunch of tests. This issue was written only with test_input in mind! (I was debugging that one and found the issue)
Printing a float, like printf("float: %f\n", 1.0); in the function on_new_event results in a Segmentation fault. Doing the same in the main function, everything works as expected.
Showcase: z3ntu@ea24333
Output of that:
root@localhost:~/libhybris/hybris/tests# ./test_input
This will work:
float: 1.000000
<note: pressed the touchscreen there>
This won't work:
Segmentation fault
gdb backtrace - mirror of the paste is here
This problem causes the test_input test to crash: https://github.com/libhybris/libhybris/blob/master/hybris/tests/test_input.c#L51-L54 .
Casting the two variables into an integer and printing them works around the issue. Sample patch: z3ntu@5773400

Having problems with LibHybris on Nexus 7 2013
Hello,
I'm trying to run LibHybris on my Nexus 7 2013, running Arch Linux, in order to get hardware acceleration and maybe get wayland running. (https://github.com/crondog/arch-flo)
I followed the steps I've seen around the web in order to build it.
In particular I followed this guide: http://linux-rockchip.info/mw/index.php?title=LibHybris
and I used these PKGBUILD to install everything as a package: http://archlinuxarm.org/forum/viewtopic.php?f=33&t=5951
I built Android (I'm using the CyanogenMod source), patched bionic, rebuilt it, extracted /system and the headers, pushed them and installed them to the tablet, then built libhybris. (you can find my /system and headers here: http://download.tuxfamily.org/davidedduos/arch-flo/ )
LibHybris builds, but whenever I try to run almost any of the tests (gps and lights seem to work/not to crash) they either segfault or simply crash. This is their output: https://gist.github.com/Davideddu/779420a5a7393929df05
What can I do to troubleshoot this?
P.S.: I'm using CM nightly, which is 4.4.4 KitKat. The bionic patch applied without complaining, so I guessed it was ok. I'm asking because I saw the version of android you normally use is 4.2.2, which is not available on the Nexus 7 2013 as it started being sold after 4.3 was released.
my_pthread_mutex_lock race condition issue
#1 static int my_pthread_mutex_lock(pthread_mutex_t *__mutex)
#2{
……
#3 if (value <= ANDROID_TOP_ADDR_VALUE_MUTEX) {
#4 realmutex = hybris_alloc_init_mutex(value);
#5 *((unsigned int *)__mutex) = (unsigned int) realmutex;
#6 }
#7 return pthread_mutex_lock(realmutex);
#8}
consider the following scenario, two threads try to call pthread_mutex_lock at the same time, as the order shown below:
Thread A: finish Line#4; [allocate realmutex for mutex(value)]
Thread B: begin to execute, finish Line#4; [allocate another realmutex for same mutex(value)]
then there is two realmutex for one single mutex(value),
thus, A & B will lock on different realmutex
the above scenario is not easy to be exposed. I added on sleep(1) between Line4 & Line5, and write one simple test(two threads call pthread_mutex_lock), to trigger this scenario.
#4 realmutex = hybris_alloc_init_mutex(value);
sleep(1);
#5 *((unsigned int *)__mutex) = (unsigned int) realmutex;
possible solution, use one lock or use RMW instruction when updating *(__mutex), if update failure, another thread must have alloc realmutex, this thread free the realmutex and reload __mutex;
Does not support qualcommon android7 platform?
Does not support qualcommon android7 platform? I tested it and failed to open the library.
is there a doc about how to use libhybris?
I look up for a doc about how to use libhybris through google,but I failed.
please help me ,thx!

Vendor libEGL and libGLESv2 symbols unresolved without env var
This issue tracks the only problem left from #368.
Some time ago, when Libhybris failed to locate symbols from vendor graphics libraries on my device, I set LIBGLESV2 and LIBEGL to point to them. The solution with env vars definition worked nicely for a while, but now it turns out it is still wrong. As I understand now, libEGL and libGLESv2 act as loaders and wrappers for proprietary libs, so they should be able to locate and load them automatically. And they actually do, so this has to be a Libhybris problem.
The problem is that some symbols (e.g. eglCreateImageKHR) are actually implemented in wrappers. So if I have both variables set, I get KWin crashing if Qt Quick hardware acceleration is enabled:
_my_eglCreateImageKHR (dpy=0x1, ctx=0x0, target=12757, buffer=0x804d5c10, attrib_list=0xbfffdc70) at egl.c:376
Before d5183fe, I could see that symbol missing in linker output.
eglCreateImageKHR is implemented in open source libEGL. If I unset LIBEGL variable, the symbol is found, and I get glEGLImageTargetTexture2DOES missing (implemented in open source libGLESv2).
Unsetting LIBGLESv2, however, would bring me back where I started with most of GL ES symbols undefined.
So, as I see it, Libhybris should look up symbols in both wrappers and vendor libraries...
Would it be ok to split some things?
As per: mer-hybris/droid-hal-device#185 (comment)
Would it be ok to split libhybris/compat off into a seperate libhybris-compat (or even hybris-compat) repository?
Only if it doesn't introduce any big problems. (Changing a manifest.xml to a different URL doesn't count as big :P).
On mer side there are usually no dependencies from hybris-hal to libhybris, which complicates things. A split would help, and would fit better in my opinion since: "repositories which are required to be built with both Android.mk and Makefile.am are kind of weird ;)".
There is a workaround so if someone is absolutely against this, please let me know.
Libhybris on NEXUS 10 with FB backend
Hi. Recently i have experimented with libhybris on Nexus 10 android 4.4.2. I was targeted on launching Weston. I found this kind of support for libhybris in weston related to FB backend. After some struggling with HAL fb on modern platform, i successfully launched weston but get only a black screen. It turned out, that WaylandNativeWindow constructor setBufferCount to 3, and there are three distinct buffers app renders to. Finish swap callback for wayland window had sent the one of this graphical buffers to compositor, but it seems that it was empty (zero data), so the app texture was stored in other buffer. As a workaround i added logic to send all of buffers from WaylandNativeWindowBuffer queue in finish swap callback and that worked for me ok. Actually, i don't even know if this is an issue or a problem in my head. So if anybody understand what i'am talking about and see some kind of problem in this, please let me know.
Incorrect TLS slot values
Hello! :)
I am porting Halium to an x86 phone and facing many issues related to architecture support. One of them is in libhybris: the library uses custom TLS slot values that do not work with x86.
https://github.com/libhybris/libhybris/blob/master/hybris/common/mm/bionic/libc/private/bionic_tls.h
So far me and all the other x86 port developers have been using their own values, but now I'm facing weird issues and think these constants may be the problem. What are these slots, what are they supposed to affect, why do they need to be changed for libhybris and how do I need to change them to be correct?
test_egl fails if libhybris is not compiled with wayland support
From test_egl.c:
if (strstr(eglQueryString(display, EGL_EXTENSIONS), "EGL_HYBRIS_native_buffer") != NULL)
{
From eglplatformcommon.cpp:
extern "C" const char *eglplatformcommon_eglQueryString(EGLDisplay dpy, EGLint name, const char *(*real_eglQueryString)(EGLDisplay dpy, EGLint name))
{
#ifdef WANT_WAYLAND
if (name == EGL_EXTENSIONS)
{
const char *ret = (*real_eglQueryString)(dpy, name);
static char eglextensionsbuf[1024];
snprintf(eglextensionsbuf, 1022, "%sEGL_HYBRIS_native_buffer2 EGL_HYBRIS_WL_acquire_native_buffer %s", ret ? ret : "",
#ifdef WANT_WAYLAND
"EGL_WL_bind_wayland_display "
#else
""
#endif
Obviously the #ifdef will allow the native buffer capability only to be patched with the EGL_HYBRIS_native_buffer2 string if WANT_WAYLAND is set. This prevents the test_egl code to execute properly.
Behaviour of WaylandNativeWindowBuffer on pmem based android device
Im just documenting the issue here incase anyone has ideas about it. This is the the best of my current knowledge, but far from complete.
What I believe the issue to be is:
1)Kernel boots up and allocates ~32MB of graphics memory using PMEM
2)Qt/SFOS loas and requests a window buffer of size width*height etc
3)PMEM receives a request for a buffer of size 32MB and allocates it ok
4)User loads a program and another request is made for a window buffer
5)PMEM fails the allocation as there is no more memory.
I have worked around this in the HTC ACE kernel by:
1)When the first successful allocation is made, remember the address
2)When a subsequent request fails, return the address of the original request
Obviously this results in apps overwriting the buffers of other apps, and has the negative result in that on SFOS, cover windows get corrupted, and the on-screen-keyboard cannot be displayed at the same time as another window (which is really quite annoying.
I have tried changing the amount of memory allocated at boot, but no matter what it is changed to, the request is always for the full amount.
I have tried forcing the size inside PMEM to width_height_depth, but it fails later when the size is different to the size of the MMAP.
Does anyone have any better ideas?
I wondered if inside libhybris, I could allocate the graphics memory at the start, then manually allocate areas to different buffers, but it doesnt sound like a great idea!

Server-side wayland buffers fail on some devices
Recently it was noticed that server-side wayland buffers do not work on devices which use QCOM_BSP. This makes using applications impossible, however disabling server-side wayland buffers can be used as a workaround which makes everything working again. So far 3 devices have shown a similar problem and using QCOM_BSP seems to be connecting the devices. On my device (iyokan, Xperia Pro) journal log shows "failed to register buffer" errors and logcat shows:
E/qdmemalloc( 4234): ION_IOC_ALLOC failed with error - Operation not permitted
E/qdgralloc( 4234): gralloc failed err=Operation not permitted
D/qdgralloc( 4310): Invalid gralloc handle (at 0x4e3e8580): ver(12/12) ints(16/12) fds(0/2) magic(@���/gmsm)

W/Adreno-EGL( 4310): <qeglDrvAPI_eglSwapBuffers:3665>: EGL_BAD_ALLOC
I'm investigating if the server-side buffers can be fixed on devices with QCOM_BSP.
linker issue: RTLD_DEFAULT & RTLD_NEXT has different value between bionic and glibc.
RTLD_DEFAULT & RTLD_NEXT has different value between bionic and glibc.
bionic
define RTLD_DEFAULT ((void*) 0xffffffff)
define RTLD_NEXT ((void*) 0xfffffffe)
glibc
define RTLD_NEXT ((void *) -1l)
define RTLD_DEFAULT ((void *) 0)
Hybris linker includes glibc headfile and thus use the RTLD_DEFAULT, RTLD_NEXT from glib;
this leads to difference when bionic built code call dlopen with RTLD_DEFAULT/RTLD_NEXT
the possible fix is to use the definition from bionic

cannot locate '__srget'
Hi !
I've been trying to use libhybris to call to a native arm android library from a linux box.
But the android_dlopen("mylib.so", RTLD_LAZY) call fails with the following error :
Cannot load library: reloc_library[1353]: 0 cannot locate '__srget'...
Basically, I compiled libhybris with android headers 22, created a c program that loads my library and put libc.so, liblog.so, libstdc++.so and libm.so under /system/lib/.
I'm not sure of anything, is this right ?
