From: Heinrich Schuchardt Date: Thu, 10 Jun 2021 21:10:52 +0000 (+0200) Subject: efi_loader: TPL_HIGH_LEVEL not allowed for CreateEvent X-Git-Url: http://git.dujemihanovic.xyz/login.html?a=commitdiff_plain;h=7891fe675d03f2407b040c472ae76050bc88c24e;p=u-boot.git efi_loader: TPL_HIGH_LEVEL not allowed for CreateEvent 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.
