CVS commit: src/sys/external/bsd/drm2/include/drm

Module Name:    src
Committed By:   mrg
Date:           Thu Feb 20 09:07:39 UTC 2020

Modified Files:
        src/sys/external/bsd/drm2/include/drm: bus_dma_hacks.h

Log Message:
in bus_dmamap_load_pglist() try a 32-element array of
bus_dma_segment_t's before attempting to allocate.

this hopefully avoids hangs i've had in X since updating
from netbsd-8 to netbsd-9 that i've tracked down to this
function failing with ENOMEM.

XXX: maybe can avoid the alloc entirely by batching these
calls in 32 segments each.

XXX pullup-9
