SDEI: Determine client EL from NS context's SCR_EL3
Currently, the dispatcher reads from SCR_EL3 register directly to determine the EL of SDEI client. This is with the assumption that SCR_EL3 is not modified throughout. However, with RAS work flows, it's possible that SCR_EL3 register contains values corresponding to Secure world, and therefore EL determination can go wrong. To mitigate this, always read the register from the saved Non-secure context. Change-Id: Ic85e4021deb18eb58757f676f9a001174998543a Signed-off-by: Jeenu Viswambharan <jeenu.viswambharan@arm.com> |
