Panfrost GPU Driver #7

Open tianjianh opened 2 months ago

tianjianh commented 2 months ago

Do we have any compiled images with panfrost driver enabled or any instructions on how to compile with it?

I try to enable it in the linux config and then compile but always get errors.

Thank you.

At present, all versions enable the Panforst driver already, Panforst is normally used, but because the use of sunxi-drm, mesa driver does not support this new drm driver, you need to manually compile sunxi-drm_dri.so to support it. Patches located at: https://github.com/AvaotaSBC/buildroot-external-avaota/tree/main/patches. The buildroot is supported with GPU + Mesa driver

Thank you for your quick response! Now I know the reason why mesa complains about the driver.

Could you please elaborate a bit more on how to manually compile sunxi drm? Should I just apply the patches to the source and run the build script? Sorry I am a newbie and don’t have much experience.

By the way, I think the default config does not turn on the Panfrost in the driver section? Should I turn it on during the built or leave it off?

Thank you again!

Accidentally close the issue, reopen it.

We already enable Panforst driver with config CONFIG_AW_DRM_PANFROST=y This version of panforst add support fot Mali-G57 and V-F Table source: https://github.com/AvaotaSBC/linux/tree/main/bsp/drivers/gpu/panfrost

You can try to build buildroot and copy the mesa driver to AvaotaOS, and enable dlcd0 in dts which will enable the GPU support, enable dlcd0 is a bug for right now, otherwise the panforst will register as /dev/dri/card0 and cause error

@SamulKyull Thanks for the information. When I try to build the buildroot with default config, I get the following error:

_ERROR: Feature "opengles2": Forcing to "ON" breaks its condition: NOT WIN32 AND NOT WATCHOS AND NOT QT_FEATURE_opengl_desktop AND GLESv2_FOUND Condition values dump: WIN32 = "" WATCHOS = "0" QT_FEATURE_opengl_desktop = "ON" GLESv2FOUND = "TRUE"

Could you please help? There seems to be a conflict between opengl and gles. Thank you!
