Subject: [PATCH 0/2] Make capsules in a contiguous virtual space
Date: Tue, 19 Dec 2017 18:49:13 +0800 [thread overview]
Message-ID: <1513680554-5682-1-git-send-email-ge.song@hxt-semitech.com> (raw)
Recently we found it failed to update firmware through capsule update
mechanism in linux-4.14 and later version.
After some investigation, the reason is firmware expects capsules in a
contiguous virtual space and this assumption is not satisfied in recent
linux versions.
Ge Song (2):
Revert "efi/capsule-loader: Use page addresses rather than struct page
pointers"
efi/capsule-loader: Request a contiguous virtual space for capsules
