Subject: Regression in Linux next with dma cma changes
Date: Tue, 26 Feb 2019 12:01:55 -0800	[thread overview]
Message-ID: <20190226200155.GE39872@atomide.com> (raw)

Hi,

Looks like commit d222e42e8816 ("dma-contiguous: do not allocate a
single page from CMA area") caused a regression at least for
omap dss where we now get the following error on init:

omapdss_dispc 58001000.dispc:
dispc_errata_i734_wa_init: dma_alloc_writecombine failed

Any ideas what might be going wrong?

Regards,

Tony
