04:23 <geobang[m]1> Hi there, just to report a minor issue about DRM failure case when testing aosp + drm_simple_fb + drm_freedereno. I am not sure where to report so drop a note here for people redirect the msg to related dev.

04:23 <geobang[m]1> The issue is simply boot AOSP with both drm_simple and drm_freedereno both dtb status = "okay" and result failure in hwcomposer aquire pixel capability. I found that arounded by two way, either disable drm_simple or remove drm_simple 'format' dts property.

04:23 <geobang[m]1> I will try to upload logcat in below url https://github.com/99degree/linux/issues/9

04:27 <geobang[m]1> It is more likely drm_fredereno can't cleanly handle pre-defined pixel format when drm transition handshaking from limited support pixel format to rich support by hw.

04:27 <geobang[m]1> That's it. Thx for reading.
