Subject: [RFC][PATCH 5/5] libdrm: omap: Add DRM_RDWR flag to dmabuf export
Date: Fri, 19 Apr 2019 21:24:55 -0700 [thread overview]
Message-ID: <1555734295-31015-6-git-send-email-john.stultz@linaro.org> (raw)
In-Reply-To: <1555734295-31015-1-git-send-email-john.stultz@linaro.org>
From: Hemant Hariyani <hemanthariyani@ti.com>
Allows mmap on dmabuf fd with MAP_SHARED and PROT_WRITE.
This fixes boot failures caused due to mmap() returning error
