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
