Intel MSS generic installation problem

[Livikin_Alexey]

Hi,

I try install MSS 2015 R6 on old RHEL 6.4 based distro with partial success. Encode work only with -vaapi option:

./sample_encode_drm h264 -i ./1280x720x420p.yuv -o ./out.h264 -w 1280 -h 720 -async 1 -vaapi
libva info: VA-API version 0.35.0

But without -vaapi encode process never end and with -async 1 next error:

And another problem -mss option dont worked with -vaapi:

./sample_encode_drm h264 -i ./1280x720x420p.yuv -o ./out.h264 -w 1280 -h 720 -async 1 -vaapi -mss 1200

I try install on this platform Centos 7.2 and all work perfectly. But for some reasons i need use this rhel 6.4 based os. Where can be problem?

Hi Alexey, 

There might be possibility that your system has multiple libva and libdrm which can cause random failures. Make sure you have Intel libva and libdrm.
If you don't, the clear libva before recompiling libva with “find /usr -name "libva*" | xargs sudo rm –rf” and with “./configure --prefix=/usr” before run “make”. Check the article on install on secondary OS -https://software.intel.com/en-us/articles/how-to-setup-media-server-studio-on-secondary-os-of-linux to make sure you have followed all the steps. Are you on Kernel 3.14.5? What is your system configuration?

Hope it helps. 

Thanks,
Surbhi

[Livikin_Alexey]

Hi Surbhi,

Yes i remove all other libdrm and libva, kernel is 3.14.5 patched from generic directory patches. Cpu is Intel(R) Core(TM) i7-4770R CPU @ 3.20GHz .  Same kernel version i setup in Centos 7.2 for verify all work fine.

ldd --version
ldd (GNU libc) 2.12

Error comming from MFXVideoCORE_SyncOperation function in kernel traces i see

[drm:drm_ioctl], pid=11079, dev=0xe200, auth=1, I915_GEM_USERPTR
[drm:drm_ioctl], ret = -19

Maybe some specific options in kernel need not only drm and i915? I use minimal kernel configuration without unused modules.

Best Regards,

Alexey.

Hi Alexey, 

Thanks for providing information. Your system is supported by MediaServer Studio so is the glibc. Can you send the o/p of few test and more info asked below - 

1. add strace to the cmd - strace ./sample_encode_drm h264 -i ./1280x720x420p.yuv -o ./out.h264 -w 1280 -h 720 -async 1 -vaapi 

2. By default async value is 4, can you try not to set async value and check if the issue exits. 

Send o/p of following cmds 

$ vainfo

$ ls -l /dev/dri

$ lspci -nn | grep VGA

Just to set the expectations clear we support CentOS 7.1 as a gold OS configuration and provide generic package with kernel 3.14.5  patches as a option to work on other Linux distributions as preferred by customer and any issues raise on other than gold OS(CentOS7.1) needs to be replicated on CentOS7.1 for us to look at. We can try to help you this issue because of the interest but can't escalate it to experts unless replicate on CentOS7.1. 

FYI - Media Server Studio 2016 release is out, in case you would like to update. This might not solve the issue you are experiencing but it will be best to see if the issue is reproducible on the latest release. 

Thanks,
Surbhi

Hi Alexey, 

Thanks for sending in the information. All the above info sent in your last post looks right, so I discussed your case with an expert and these msgs doesn't look right -
[drm:drm_ioctl], pid=11079, dev=0xe200, auth=1, I915_GEM_USERPTR
[drm:drm_ioctl], ret = -19
So, would like to confirm if you have rebuild the libdrm last when we discussed to remove multiple libva and libdrm. If not, please remove the libdrm, recompile and install them. Also, what version of gcc version do you have? Please update to 4.7 or higher as this is a pre-requisite. You can refer to this article to find the cmds for rebuilding kernel and updating gcc. 

Thanks,
Surbhi

[Livikin_Alexey]

Hi Surbhi,

gcc already updated to 5.3.0 version:

gcc -v
Using built-in specs.
COLLECT_GCC=gcc
COLLECT_LTO_WRAPPER=/usr/libexec/gcc/x86_64-unknown-linux-gnu/5.3.0/lto-wrapper
Target: x86_64-unknown-linux-gnu
Configured with: ./configure --prefix=/usr --disable-multilib
Thread model: posix
gcc version 5.3.0 (GCC)

libdrm and libva recompilled from generic directory, nothing change. Previously i use precompilled from installation with identicall results.

Best Regards,

Alexey.

Hi Alexey,

Have you merge the MSS patches to kernel when you build the kernel 3.14.5 ?

How did you build your kernel ?

which gcc version used when you build the kernel ?

I suggest you build kernel with RHEL build-in gcc and following "How to setup MSS on CentOS 6.5" in  How to setup Media Server Studio on Secondary OS of Linux

Thanks,

Zachary

[Livikin_Alexey]

Hi Zachary,

Yes i applyed patches with command

for i in ../intel-kernel-patches/*.patch; do patch -p1 < $i; done

I attached my config for 3.14.5

Build with next commands make -j 8 next make modules_install and make install. Gcc version for build kernel same 5.3.0

Best Regards,

Alexey.

[Jiandong_Z_Intel]

Hi Alexey,

Have you tried to use "make olddefconfig" for configure your kernel before run "make -j 8" ?

And, I suggest you use RHEL 6.4 build-in gcc to compile your kernel. following command line can help to restore your gcc

[user@host]# yum remove gcc gcc-c++
[user@host]# yum install gcc gcc-c++

Because some upgrade gcc version may cause run issue.  after build and install kernel you can use 5.3.0.

And can you share how did you upgrade gcc to 5.3.0 ?

Thanks,

Zachary

[Livikin_Alexey]

Hi Zachary,

After some studing installation manuals i found decission. Its "

Important Note: With using own kernel configuration please make sure CONFIG_MMU_NOTIFIERS=y is enabled. It can be disable implicitly with disabling virtualization support.

"

Virtualisation disabled in my config and notifiers not setted. After i set him and recompile kernel all work great. Documentation not quite right parameter must be named CONFIG_MMU_NOTIFIER not CONFIG_MMU_NOTIFIERS.

Anyway thanx for help.

Best Regards,

Alexey.

[Jiandong_Z_Intel]

Hi Alexey,

Good to know it worked for you. and Thank you for share your knowledge. It will help to others.

Thanks,

Zachary
