2024-01-11MdePkg/BaseLib: Fix boot DxeCore hang on riscv platform王洋1-7/+25
For scene of HandOffToDxeCore()->SwitchStack(DxeCoreEntryPoint)-> InternalSwitchStack()->LongJump(),Variable HobList.Raw will be passed (from *Context1 to register a0) to DxeMain() in parameter *HobStart. However, meanwhile the function LongJump() overrides register a0 with a1 (-1) due to commit (ea628f28e5 "RISCV: Fix InternalLongJump to return correct value"), then cause hang. Replacing calling LongJump() with new InternalSwitchStackAsm() to pass addres data in register s0 to register a0 could fix this issue (just like the solution in MdePkg/Library/BaseLib/AArch64/SwitchStack.S) Signed-off-by: Yang Wang <wangyang@bosc.ac.cn> Cc: Bamvor Jian ZHANG <zhangjian@bosc.ac.cn> Cc: Andrei Warkentin <andrei.warkentin@intel.com> Cc: Liming Gao <gaoliming@byosoft.com.cn> Cc: Michael D Kinney <michael.d.kinney@intel.com> Cc: Sunil V L <sunilvl@ventanamicro.com> Cc: Zhiguang Liu <zhiguang.liu@intel.com> Reviewed-by: Ran Wang <wangran@bosc.ac.cn> Reviewed-by: Andrei Warkentin <andrei.warkentin@intel.com>
2023-03-08MdePkg: BaseLib: don't log in RISCV InternalSwitchStackAndrei Warkentin1-8/+0
InternalSwitchStack may be called with a TPL high enough for a DebugLib implementation to assert. Other arch implementations don't log either.
