Intel BayTrail-T SOC: Intel hybrid driver doesn't work

[Svyatko]

Is somebody using this “Intel hybrid driver”?

According to Wikipedia:

Partially-accelerated decoding on Linux only (Haswell Refresh to Skylake)

CPU + GPU via shaders work together to decode VP9.

Intel hybrid driver declares support for Intel BayTrail-M:

Will xf86-video-intel help?

[Svyatko]

ILL driver works with libva1, doesn’t work with libva2.

:~> /usr/bin/nm --demangle -D /home/mypc/Temp/intel-hybrid-driver-1.0.2-bp156.4.4.x86_64/usr/lib64/dri/hybrid_drv_video.so | grep vaDriverInit
000000000001c530 T __vaDriverInit_0_34

New driver from 22.3.5:

0000000000068a90 T __vaDriverInit_1_16

If this is true then how to solve this?

[Svyatko]

Updated driver is needed?

ILL openSUSE devs have lost needed patch.
It was there, but now it is lost.

@Svyatko you do realize the hybrid driver is a dead project? https://github.com/intel/intel-hybrid-driver

When I needed OpenCL on AMD, I’ve created method for installing driver. I went beyond AMD constraints. Then I’ve created instructions:

https://en.opensuse.org/SDB:AMD_GPGPU

When I needed Leap on device with 32-bit EFI, I’ve created method for installing it. Then I’ve created instructions:

Easy way of installing Leap on 32-bit EFI system

I’ve tried again installing Leap on tablet PC with 32-bit EFI and 64-bit CPU (Intel Bay Trail-T). Now Leap 15.6 installs with minimal changes. Create modified installation media: 1.1 Prepare USB flash drive. For DVD installation ISO you need capacity 8 GB or more (DVD capacity = 4.7 GB = 4.3 GiB > 4 GB). 1.2.

Elaborating Intel hybrid driver case:

Intel hybrid driver versions from Repology:

intel-hybrid-driver package versions - Repology

We see version 2.0.0 for some distributions, 1.0.2 for openSUSE & others.

Intel hybrid driver patches from Gentoo:

ILL patch

intel-hybrid-codec-driver-2.0.0-vadriverinit-fix.patch « files «...

is needed to solve that error.

OpenSUSE uses 2 from 5 available patches.

I filed Bug 1234858 - Intel hybrid driver “hybrid_drv_video.so” for VA API (VAAPI) does not work.

ILL Intel hybrid driver doesn’t work since OS upgrade to libva2 from libva1.

@Svyatko If it’s important to you branch the package, apply the patches, test and submit?

No need to add any quotes, openSUSE is a do-ocrity…

Some news:
It is possible to get Intel hybrid driver running, but:

1. It provides VP8 encode for Intel GPU Gen 7+, but VP8 format is not needed anymore. Gen 6+ GPUs support h.264 hw decode & encode with Intel VAAPI driver.
2. It provides VP9 decode for Intel GPU Gen 7.5+, but my Bay Trail device has Gen 7. I’ve tried to get supported device, but cannot find it at appropriate price.
3. Apollo Lake, Kaby Lake and newer chips have hardware VP9 decode with newer Intel Media Driver.
4. For Haswell & newer CPUs I recommend usage of Core i3, i5, i7 chips, which have AVX2 (and x86-64-v3) support. VP9 and AV1 codecs have full support for AVX2 acceleration. Old Intel Celeron & Pentium chips lack support for AVX, change them if possible.
5. Bay Trail chips can play VP9 and AV1 files at 720p@30 fps with software decoder. But they cannot play VP9 and AV1 at 1080p@30 or 720p@60.
6. Libvpx VP9 decoder supports SSSE3 and SSE4.1 acceleration, Dav1d AV1 decoder supports SSSE3 acceleration.
7. Some speedup can be achieved by using newer versions of decoders. You can get them from Experimental repos. You can get Dav1d decoder from VLC - Videolan.
8. It is possible to use OpenCL or Vulkan GPGPU for decoding, but who needs this?
9. Cherry Trail for tablets can use Intel hybrid driver - Gen 8LP is supported, file is available, but possibly feature is not properly implemented.

BTW, decoders (and other software) are dropping SSE2 acceleration, you need at least SSSE3 (it is newer than SSE3).
IDK how AMD Phenom CPUs will decode - by FPU?
MMX also is in dropping phase.

You can find supported devices by chip ID (= pair VID:PID) here. To get chip ID for GPU use

inxi -aG

You will get pair VID:PID. VID = vendor ID. VID = 8086 for Intel.

Part for Cherry View chips with PIDs:

#define PCI_CHIP_CHV_0		0x22B0
#define PCI_CHIP_CHV_1		0x22B1
#define PCI_CHIP_CHV_2		0x22B2
#define PCI_CHIP_CHV_3		0x22B3


#define IS_CHERRYVIEW(devid)   (devid == PCI_CHIP_CHV_0 || \
				devid == PCI_CHIP_CHV_1 || \
				devid == PCI_CHIP_CHV_2 || \
				devid == PCI_CHIP_CHV_3)

Chip ID is 8086:22B0 & etc.

I’m using Gen 7 GPU. Your GPU has VP9 hw acceleration, mine - not.
Reboot is not needed.
Intel media driver doesn’t work with Gen 7 GPUs and I never have installed it.
For your GPU it is better to use Intel media driver.

No need, VLC libs work OK. AVC works OK with hw acceleration.

AVC works OK with hw acceleration. I need VP9 acceleration.

Cheap Intel SoC have no hardware circuits for decoding VP9 videos. Did you check the intel datasheet(s) of your SoC for VP9 hardware accelerated Video decoding before you wrote this novels?

[GrandDixence2]

Intel datasheet of your SoC should looks like that:
