Intel Gallium3D Driver Merged Into Mesa 21.2 For Gen4 Through Haswell Graphics

[discordian]

Yeah, my old Haswell has to do until DD5 & Pcie5 & Ryzen "Fat APU" & no chip-shortage-price-hike happened.
(Or ARM/RISC-V took over on the desktop, whatever happens first)

If you want to easily test on Ubuntu I enabled crocus in my PPA: https://launchpad.net/~oibaf/+archiv...phics-drivers/

Thanks for keeping older ThinkPads alive and relevant, as well as Iris 5xxx systems that were not too shabby at the time and are still perfectly fine today, except for incomplete Vulkan support (due to hardware shortcomings, apparently).

As far as (light) gaming is concerned, support for Gallium Nine would have been a nice-to-have back when the hardware was new. Perhaps if Intel went with Gallium sooner, OpenGL support would have progressed more quickly as well? Who knows. All I know is that the hardware has been stuck with OpenGL pre-4.0 for so long, it basically stagnated to the point of obsolescence. When OpenGL 4.5 finally came, it was too late. Additional extensions such as GL_ARB_bindless_texture never made it into i965, so native titles such as Tomb Raider (2013) couldn't make use of it.

What's important now is that models such as the ThinkPad T420, T430, T440 will not be left to die and will still work out of the box without the need for a separate legacy Mesa, in case plans to deprecate older drivers goes through. They will remain relevant until desktop environments also deprecate any and all OpenGL paths and go Vulkan only in a few years.

did they fix this: https://dri.freedesktop.org/wiki/I965Todo/ problem plus I965Errata

it will be nice if someone does something about broken Hardware video acceleration in Haswell and older IGPU with libva-intel-driver. ( Broadwell (2014) and newer are supported by intel-media-driver.)

and maybe beignet (old OpenCL drivers ) too

i would try it and see if this fix tearing problem with mpv and any media player

That is good news to my GM45 laptop and also a really good work that shows Open Source drivers are great!

Has Beignet ever been in a functional state? I guess Gallium's Clover has a better chance to become functional for gen6/7 than Beignet.

I'm fairly ignorant regarding accelerated video decoding. Is H264 HW acceleration still relevant with VP8/VP9/AV1 streaming? Is generic video acceleration through shaders possible? Is it present today? Does it offer any speed or power consumption advantages over pure CPU decoding? Does all this even matter if the codec is already digested well by the CPU at reasonable resolutions?

Thanks airlied and imirkin !
My HTPC might have a future this way!

chocolate I ripped my video (DVD, BD) collextion to h264 and I don't want to reencode everything just for a different codec. Also streaming under Linux is still non-HD where hardware support only matters in terms of energy savings.

If you are seeing any sort of tearing with mpv, then you are obviously doing it wrong!™

[uid313]

Does or will this Crocus driver have any advantages over the existing driver?

VAAPI works fine here on IVB:
