Linux/AM3358: Can't load graphic drivers

Simon Benoit
Prodigy 100 points

Part Number: AM3358
Other Parts Discussed in Thread: DA8XX, UKERNEL, TPS65218

Tool/software: Linux

Hi,

After many research on the forums, I have found plenty of build, git commits, but no direct answer to my question.

I have an AM3358 chip and I want to get the OpenGL ( egl ) working. So I tried to install the gfx drivers and the sgx drivers ... I'm having trouble with both so

First question : Do I need ti-gfx AND ti-sgx-km packages ???

2nd question : How do I make it work :) ?

I just downloaded the kernel 4.9 from the newest SDK ( 4.00 ) for am335x. Its added to my buildroot build sequence, it builds fine.

I added TI-SGX-... from that same SDK and added it as a custom package in buildroot ( instead of the other ti-sgx-km ). The build works great, but it can't load .

PVR:(Error): OpenServices: drmOpen failed [120, /pvr_bridge_u.c]
PVR:(Error): PVRSRVInitSrvConnect: PVRSRVConnect failed [2572, /bridged_pvr_glue.c]
PVR:(Error): SrvInit: PVRSRVInitSrvConnect failed (4) [37, /srvinit.c]
PVR:(Error): main: SrvInit failed (4) [47, /pvrsrvinit.c]

I'd like to know what i'm missing here. 

Thanks

    Hi,

    First question : Do I need ti-gfx AND ti-sgx-km packages ???

    Yes, you need both. You can find the user space libraries in the software manifest in the Docs folder in linux sdk.  Download them from the link it is pointed there & use make install to add them to your filesystem.

    2nd question : How do I make it work :) ?

    You can rebuild the kernel modules as described here: https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/791/INSTALL

    Then you should install the sgx libraries from your first question. Then copy the kernel driver in your newly create sdk (with all the user space libraries) & once you boot your board, just insmod the sgx driver. 

    Best Regards, 
    Yordan

    As I said earlier, it's able to build and I have the right defines. Once I want to install the module, I get the error :
    PVR:(Error): OpenServices: drmOpen failed [120, /pvr_bridge_u.c]
    PVR:(Error): PVRSRVInitSrvConnect: PVRSRVConnect failed [2572, /bridged_pvr_glue.c]

    I rolled back to my Buildroot original version. Kernel 4.4 ans the ti-sgx that comes with buildroot ( with a slight modification in a header path )

    I still don't think the module is properly mounted tho, it shows in lsmod

    Seems you have the module already loaded. You have to install libgbm2 package on your board.

    Ok, I resolved one problem with the 24 bits that was unsupported by the pvrsrvkm

    Now the omapfb can't load. Could it be because there's already a fb0 driver in my /dev ans I already have a hook on the framebuffer ????

    Update :
    I build the da8xx_fb driver and tilcdc ad module, unloaded them then I was able to go further with this module. But the omapfb is stuck at

    Hi Yordan,

    Why both, ti-gfx and ti-sgx, are required?

    Thanks!

    Hello Stefan,

    Depending on the installed kernel driver, you will need to choose the proper one.

    Linux Kernel version
    Linux buildroot 4.9.51 #1 PREEMPT Thu Sep 28 16:52:59 CEST 2017 armv7l GNU/Linux

    I built it with TI linux kernel 4.9.51, ti-sgk-um (ti-img-sgx/1.14.3699939) and ti-sgx-km (ti-img-sgx/1.14.3699939/k4.9).
    In ti-sgx-km.mk PRODUCT_NAME is set to ti335x.


    I don't want to use wayland (libwayland-server.so and libgbm.so.2).
    I've temporarily fixed the following errors
    : error while loading shared libraries: libgbm.so.2: cannot open shared object file: No such file or directory
    : error while loading shared libraries: libwayland-server.so.0: cannot open shared object file: No such file or directory
    by copying both libraries into /usr/lib.

    Thank you!

    Stefan

    In my case, I didn't get much help from TI ... they always refer us to that wiki page with missing documentation. There's no straight information on when to use GFX and when to use SGX.

    For the kernel 4.9 I suppose you are using the SKG-KM and SGX-UM driver from the good driver branch. In my case, I had to put printk on every line of the lcd driver to realise that there was a bad value in our device tree. The smallest mistake will make the driver fail to mount.

    Good luck !

    Can you post the exact steps you use to create that build with buildroot? Then I will tell you what exactly went wrong.

    I've downloaded buildroot-2017.08

    make menuconfig
    - use linaro toolchain 2017.02
    - use systemd
    - kernel: git://git.ti.com/ti-linux-kernel/ti-linux-kernel.git; branch=ti-linux-4.9.y
    - config: modified tisdk_am335x-evm_defconfig
    - dts: modified am335x-boneblack.dts
    - select ti-sgx-km and ti-sgx-um (added current ti git-repo and branch for both, see prior post)
    - select Qt5: qt5base, gui module, opengl support (opengl es 2.0+), eglfs support, default graphical platform (eglfs), dbus module, qt5declarative, quick module, qt5quickcontrols, ...

    It works with PROCESSOR-SDK-LINUX-AM335X 03.02.00.05, but it uses too much memory!
    Now, I work with buildroot to get a minimal, memory-efficient linux system.

    Thanks!

    Can you attach the modified tisdk_am335x-evm_defconfig ?

    The buildroot config of ti-sgx-um is also outdated. Attached is the modified ti-sgx-um.mk

    /cfs-file/__key/communityserver-discussions-components-files/791/3324.ti_2D00_sgx_2D00_um.mk.txt

    I've modified the defconfig file to kernel 4.9.51 (see attachment).

    /cfs-file/__key/communityserver-discussions-components-files/791/tisdk_5F00_am335x_2D00_evm_5F00_defconfig.txt

    After that I get following messages, if I run /etc/init.d/rc.pvr:

    # ./rc.pvr start
    [   63.480157] [drm] Initialized pvr 1.14.3699939 20110701 on minor 1

    Try exporting "export QT_QPA_PLATFORM=eglfs"

    Hi Kemal,

    Thanks!

    Unfortunately, it doesn't work.

    If you export QT_QPA_EGLFS_INTEGRATION the "EGL library doesn't support Emulator extensions" error should be missed. Can you try?
    export QT_QPA_EGLFS_INTEGRATION=none
  • 0 in reply to Kemal R. Shakir

    Hi Kemal,

    Thanks!

    Solution:
    - Create and add package BR2_PACKAGE_TI_SGX_LIBGBM (git://git.ti.com/glsdk/libgbm.git)
    - BR2_PACKAGE_WAYLAND=y (pvrsrvctl needs libwayland-server.so.0)
    - BR2_PACKAGE_LIBDRM=y, BR2_PACKAGE_LIBDRM_OMAP=y

    - ti-sgx-um.mk:
    Add lines
        mkdir -p $(TARGET_DIR)/lib/gbm
        ln -sf ../libpvrGBMWSEGL.so.1.14.3699939 $(TARGET_DIR)/lib/gbm/gbm_pvr.so
    to TI_SGX_UM_INSTALL_CONF

    - qt5base.mk:
    ...
    # Uses libgbm from mesa3d
    ifeq ($(BR2_PACKAGE_MESA3D_OPENGL_EGL),y)
    QT5BASE_CONFIGURE_OPTS += -kms -gbm
    QT5BASE_DEPENDENCIES += mesa3d
    else ifeq ($(BR2_PACKAGE_TI_SGX_UM),y)
    QT5BASE_CONFIGURE_OPTS += -kms -gbm
    else
    QT5BASE_CONFIGURE_OPTS += -no-kms
    endif
    ...
    ifeq ($(BR2_PACKAGE_MESA3D_OPENGL_EGL),y)
    QT5BASE_INSTALL_LIBS_$(BR2_PACKAGE_QT5BASE_EGLFS)      += Qt5EglFsKmsSupport
    endif
    ifeq ($(BR2_PACKAGE_TI_SGX_UM),y)
    QT5BASE_INSTALL_LIBS_$(BR2_PACKAGE_QT5BASE_EGLFS)      += Qt5EglFsKmsSupport
    endif
    else
    QT5BASE_INSTALL_LIBS_$(BR2_PACKAGE_QT5BASE_EGLFS)      += Qt5EglDeviceIntegration
    endif

    - export QT_QPA_EGLFS_INTEGRATION=none

    Can you share your BR2_PACKAGE_TI_SGX_LIBGBM .mk file?

    Thank you Stefan. That confirms that I am building those correctly. Can you also attach your buildroot defconfig? I must have something set wrong there.

    Also, are you able to run the kmscube demo? That is where I'm getting stuck, specifically with libgbm throwing a segmentation fault.

    I figured out the problem.

    My build environment was automatically adding the following compiler flags. Removing these fixed the problem.

    -D_LARGEFILE_SOURCE
-D_LARGEFILE64_SOURCE
-D_FILE_OFFSET_BITS=64

    Hi,

    I use this TI linux kernel repo: git://git.ti.com/ti-linux-kernel/ti-linux-kernel.git

    BR2_LINUX_KERNEL_CUSTOM_REPO_URL="git://git.ti.com/ti-linux-kernel/ti-linux-kernel.git"
    BR2_LINUX_KERNEL_CUSTOM_REPO_VERSION="ti-linux-4.9.y"

    I don't know the difference to git://git.ti.com/processor-sdk/processor-sdk-linux.git
