The 32x8 modifier  added in PATCH 16/16:

+/* used from rk3576, afbc 32*8 half mode */
+static const uint64_t format_modifiers_rk3576_afbc[] = {
+       DRM_FORMAT_MOD_ARM_AFBC(AFBC_FORMAT_MOD_BLOCK_SIZE_32x8 |
+                               AFBC_FORMAT_MOD_SPLIT),
+

I write an ovltest[0] tool which can take linear/AFBC rgb/yuv data from a file, 
then
commit to drm driver, I use this tool for most basic format test.

But when tested on weston, I found that weston does not use the AFBC format for 
display,
don't know why.

I think this is similar to what modetest dump：
