2017-09-29MdeModulePkg/Tpl: Fix negative value left shiftHao Wu1-3/+9
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=695 Within function CoreRestoreTpl(), left shift a negative value -2 is used in: "while (((-2 << NewTpl) & gEventPending) != 0) {" which involves undefined behavior. According to the C11 spec, Section 6.5.7: > 4 The result of E1 << E2 is E1 left-shifted E2 bit positions; vacated > bits are filled with zeros. If E1 has an unsigned type, the value > of the result is E1 * 2^E2 , reduced modulo one more than the > maximum value representable in the result type. If E1 has a signed > type and nonnegative value, and E1 * 2^E2 is representable in the > result type, then that is the resulting value; otherwise, the > behavior is undefined. This commit refines the code logic to avoid left shifting the negative value.

2010-02-13Update DXE Core to be compatible with PI 1.2 SMM Drivers.mdkinney1-7/+18
PI 1.2 SMM Drivers are allowed to call UEFI/DXE services and Protocols from the entry point of the PI 1.2 SMM Driver. These UEFI/DXE services and Protocols may directly or indirectly calls the UEFI Boot Services RaiseTPL() and RestoreTPL(). These UEFI Boot Services use the CPU Architectural Protocol to enable interrupts if the TPL level is below TPL_HIGH_LEVEL and enable interrupts of the TPL is at TPL_HIGH_LEVEL. Interrupts should be masked while executing SMM drivers, so if a direct or indirect call to the UEFI Boot Service RestoreTPL() would enable interrupts, then an interrupt could be incorrectly delivered in SMM context. The solution is for the DXE Core to register for the PI 1.2 SMM Base2 Protocol. If that protocol is present in the platform, then the DXE Core can use the SMM Base 2 Protocol's InSmm() function to determine if the platform is currently executing in SMM content. If the current context is in SMM, then do not allow any requests to be forwarded to the CPU Architecture Protocol to enable interrupts. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@9997 6f19259b-4bc3-4df7-8a09-765794883524
