That means that you're CPU/GPU is too old and is not supported by intel-media-driver. As a workaround, you can set the environment variable LIBVA_DRIVER_NAME to i915 (or remove intel-media-va-driver from your system). But in any case, the driver should at least bail out if it detects an unsupported platform before running into illegal instructions. This is currently tracked upstream at https://github.com/intel/media-driver/issues/1081 Cheers > > I have tryed compiling the package from source, but after tweaking the flags > to > set -march=native, the compilation fails: > > In file included from > [...]/intel-media-driver-20.3.0+dfsg1/media_driver/linux/common/cm/hal/cm_mem_os.h:30, > from > [...]/intel-media-driver-20.3.0+dfsg1/media_driver/agnostic/common/cm/cm_mem.h:128, > from > [...]/intel-media-driver-20.3.0+dfsg1/media_driver/agnostic/common/cm/cm_buffer_rt.cpp:33: > /usr/lib/gcc/x86_64-linux-gnu/10/include/smmintrin.h: In function ‘void > CmFastMemCopyFromWC(void*, const void*, size_t, CPU_INSTRUCTION_LEVEL)’: > /usr/lib/gcc/x86_64-linux-gnu/10/include/smmintrin.h:582:1: error: inlining > failed in call to ‘always_inline’ ‘__m128i _mm_stream_load_si128(__m128i*)’: > target specific option mismatch > 582 | _mm_stream_load_si128 (__m128i *__X) > | ^~~~~~~~~~~~~~~~~~~~~ > In file included from > [...]/intel-media-driver-20.3.0+dfsg1/media_driver/agnostic/common/cm/cm_mem.h:128, > from > [...]/intel-media-driver-20.3.0+dfsg1/media_driver/agnostic/common/cm/cm_buffer_rt.cpp:33: > [...]/intel-media-driver-20.3.0+dfsg1/media_driver/linux/common/cm/hal/cm_mem_os.h:201:53: > note: called from here > 201 | xmm3 = _mm_stream_load_si128(mmSrc + 3); > | ~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~ > > I am wondering what would be a good solution to at least avoid crashes... > > Regards, > Christophe > > -- System Information: > Debian Release: bullseye/sid > APT prefers testing > APT policy: (500, 'testing') > Architecture: amd64 (x86_64) > Foreign Architectures: i386 > > Kernel: Linux 5.2.0-2-amd64 (SMP w/2 CPU threads) > Kernel taint flags: TAINT_WARN > Locale: LANG=C.UTF-8, LC_CTYPE=C.UTF-8 (charmap=UTF-8), LANGUAGE not set > Shell: /bin/sh linked to /bin/dash > Init: systemd (via /run/systemd/system) > LSM: AppArmor: enabled > > Versions of packages intel-media-va-driver depends on: > ii libc6 2.30-4 > ii libgcc-s1 10.2.0-16 > ii libigdgmm11 20.3.2+ds1-1 > ii libstdc++6 10.2.0-16 > ii libva2 [libva-driver-abi-1.9] 2.9.0-1 > > intel-media-va-driver recommends no packages. > > intel-media-va-driver suggests no packages. > > -- no debconf information -- Sebastian Ramacher
