* MdePkg/BaseLib: Fix boot DxeCore hang on riscv platform王洋2024-01-113-7/+63
| | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* MdePkg: Implement RISC-V Cache Management OperationsDhaval2023-12-192-1/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement Cache Management Operations (CMO) defined by RISC-V spec https://github.com/riscv/riscv-CMOs. Notes: 1. CMO only supports block based Operations. Meaning cache flush/invd/clean Operations are not available for the entire range. In that case we fallback on fence.i instructions. 2. Operations are implemented using Opcodes to make them compiler independent. binutils 2.39+ compilers support CMO instructions. Test: 1. Ensured correct instructions are refelecting in asm 2. Qemu implements basic support for CMO operations in that it allwos instructions without exceptions. Verified it works properly in that sense. 3. SG2042Pkg implements CMO-like instructions. It was verified that CpuFlushCpuDataCache works fine. This more of less confirms that framework is alright. 4. TODO: Once Silicon is available with exact instructions, we will further verify this.

* MdePkg: Rename Cache Management Function To Clarify Fence Based OpDhaval2023-12-192-6/+6
| | | | | | | | | | | | | | | | | | | | There are different ways to manage cache on RISC-V Processors. One way is to use fence instruction. Another way is to use CPU specific cache management operation instructions ratified as per RISC-V ISA specifications to be introduced in future patches. Current method is fence instruction based, rename the function accordingly to add that clarity.

* MdePkg/BaseLib: Fix CRC16-ANSI calculationPedro Falcato2023-12-031-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4609 The current CalculateCrc16Ansi implementation does the following: 1) Invert the passed checksum 2) Calculate the new checksum by going through data and using the lookup table 3) Invert it back again This emulated my design for CalculateCrc32c, where 0 is passed as the initial checksum, and it inverts in the end. However, CRC16 does not invert the checksum on input and output. So this is incorrect. Fix the problem by not inverting input checksums nor output checksums. Callers should now pass CRC16ANSI_INIT as the initial value instead of "0". This is a breaking change. This problem was found out-of-list when older ext4 filesystems (that use crc16 checksums) failed to mount with "corruption".

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit is code optimization to InternalAllocateAlignedPages of SmmMemoryAllocationLib which can reduce free memory fragments. Also it can reduce one pre-allocation page. Let's take a simple example: The expected pages size is 8KB, Alignment value is 8KB. In original InternalAllocateAlignedPages(), the first step is to allocate 4 pages and then find the first 8KB-aligned address in allocated 4 pages. If the upper limit address of allocated 4 pages is already 8KB aligned, then the allocated 4 pages contains two 8KB-aligned 8KB ranges. The lower 2 pages will be selected and removed from free pages. Then the higher 2 pages will be free. Since the whole memory allocation is from high address to low address, then the higher 2 pages cann't be merged with other free pages, causing the free memory fragments. However, when only allocate 3(2+2-1) pages, we can avoid the free memory fragments in specific case. Also 3 pages must contain a 8KB-aligned 8KB range, which meets the requirement. If the upper limit address of allocated 3 pages is 8KB-aligned, then the higher 2 pages range of allocated 3 pages is 8KB-aligned and will be selected and removed from free pages. The remaining lower one page of allocated 3 pages will be free and merged with left lower free memory. This can reduce free memory fragments in smm.

* MdePkg/BasePeCoffLib: Deal with broken debug directoriesArd Biesheuvel2023-05-051-0/+15
| | | | | | | | | | | | | | | | | | | | | | | Older versions of GenFw put the wrong value in the debug directory size field in the PE/COFF header: instead of putting the combined size of all the entries, it puts the size of the only entry it creates, but adds the size of the NB10 payload that the entry points to. This confuses the loader now that we started using additional debug directory entries to describe DLL characteristics. GenFw was fixed in commit 60e85a39fe49071, but the binaries that were generated with it still need to be supported. So let's detect this condition, and check whether the size of the debug directory is consistent with the NB10 payload: if we should expect additional directory entries where we observe the NB10 payload, the size field is clearly wrong, and we can break from the loop.

* MdePkg/BaseLib AARCH64: Make LongJump() BTI compatibleArd Biesheuvel2023-03-301-2/+1
| | | | | | | | | | | | | | | | | | Currently, the AArch64 implementation of LongJump() avoids using the RET instruction to perform the jump, even though the target address is held in the link register X30, as the nature of a long jump implies that the ordinary return address prediction machinery will not be able to make a correct prediction. However, LongJump() is rarely used, and the return stack will be out of sync in any case, so this optimization has little value in practice, and given that indirect calls other than function returns require a BTI landing pad at the call site, this optimization is not compatible with BTI. So let's just use RET instead. Signed-off-by: Ard Biesheuvel <ardb@kernel.org> Reviewed-by: Leif Lindholm <quic_llindhol@quicinc.com> Reviewed-by: Oliver Smith-Denny <osd@smith-denny.com>
