Hi All, My name is Przemysław Gierszyński and I work as a Firmware Engineer in Intel Technology Poland. I was doing some work that required review of some parts of EDK2 and I think I have found a small bug in ArmPkg module. Here below are some details concerning the issue: File: edk2/ArmPkg/Library/ArmArchTimerLib/ArmArchTimerLib.c Function: TimerContructor ( VOID ) - line 56 Description: The comment above says: "If the security extension is not implemented, set Timer Frequency here.". In releases from the past in the if condition there was direct accessing to ID_PFR1, and it was changed in the commit shown below. [cid:image001.png@01D93185.A4DC9070] But if we go into the body of the ArmHasSecurityExtensions () function, we can see that the result of the function is a negation of the condition from the past: [cid:image002.png@01D93186.59443040]
Proposal of solution: Change the if condition in TimerContructor () function from: if (ArmHasSecurityExtensions ()) to if (!ArmHasSecurityExtensions ()) Thank you for your help!
