[PATCH] drm/lima: allow to retry when allocating memory for BO

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Currently, when allocating the memory for BO by Mesa, the lima kernel
driver set only GFP_DMA32 flag; and this allocation may fail when the
memory is relatively adequate, thus retrying is needed.

Add the GFP flags for retrying memory allocation.
