Subject: [PATCH 1/1] efi_loader: TPL_HIGH_LEVEL not allowed for CreateEvent
Date: Thu, 10 Jun 2021 23:25:58 +0200 [thread overview]
Message-ID: <20210610212558.23333-1-xypron.glpk@gmx.de> (raw)
According to chapter 7.1 "Event, Timer, and Task Priority Services"
TPL_HIGH_LEVEL should not be exposed to applications and drivers.
According to the discussion with EDK II contributors this implies that
CreateEvent() shall not allow to create events with TPL_HIGH_LEVEL.
Cf. https://edk2.groups.io/g/devel/message/76337
