Subject: Re: [PATCH] drm/msm: Fix MSM_INFO_GET_IOVA with carveout
Date: Sun, 3 Jan 2021 02:30:18 +0100 [thread overview]
Message-ID: <63647a5d-e621-b2ce-fb2c-587b5a49f697@somainline.org> (raw)

Kind reminder that MSM8974, 8994, 8992 and friends are held back by the lack of IOMMU support upstream. There has been an attempt back in 2014(!) [1], but it was either overlooked or forgotten about ever since. I'd be more than happy to see someone look into this, as I have some other bits (almost) ready for both 8974 and 94, but MMUs aren't something I understand well enough yet.
