2017-02-22UefiCpuPkg/ExceptionHandlerAsm.S: Fix code length issue with GCC 5.4Jeff Fan
X64\ExceptionHandlerAsm.S define MARCO to set up 32 IDT entries header. It assume GCC compiler will generate the same code length on the following instrction for each IDT entry. jmp ASM_PFX(CommonInterruptEntry) It works with GCC 4.x. However, GCC 5.4 will generate different code size of IDT entry code per the offset value from CommonInterruptEntry address. We should use DB to make sure each IDT entry header has the same size whatever compiler version. .ASM and .nasm used the different solution and do not have this issue. https://bugzilla.tianocore.org/show_bug.cgi?id=389 Cc: Liming Gao <liming.gao@intel.com> Cc: Feng Tian <feng.tian@intel.com> Cc: Michael D Kinney <michael.d.kinney@intel.com> Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Jeff Fan <jeff.fan@intel.com> Reviewed-by: Liming Gao <liming.gao@intel.com>

2016-11-29UefiCpuPkg/MpInitLib: wait no longer than necessary for initial AP startupLaszlo Ersek
Sometimes a platform knows exactly how many CPUs it has at boot. It should be able to - set PcdCpuMaxLogicalProcessorNumber dynamically to this number, - set PcdCpuApInitTimeOutInMicroSeconds to a very long time (for example MAX_UINT32, approx. 71 minutes), - and expect that MpInitLib wait exactly as long as necessary for all APs to report in. Other platforms should be able to continue setting a reasonably large upper bound on supported CPUs, and waiting for a reasonable, fixed amount of time for all APs to report in. Add this functionality. The TimedWaitForApFinish() function will return when all APs have reported in, or the timeout has expired -- whichever happens first. (Accessing these PCDs dynamically is safe. The PEI and DXE phase instances of this library are restricted to PEIM and DXE_DRIVER client modules, thus the PCD accesses cannot be linked into runtime code.)

For long mode DXE, we will disable paging on AP to protected mode to execute AP safe loop code in reserved memory range under 4GB. But we forget to allocate stack for AP under 4GB and AP still are using original AP stack. If original AP stack is larger than 4GB, it cannot be used after AP is transferred to protected mode. Besides MwaitSupport == TRUE, AP stack is still required during phase of disabling paging in long mode DXE. Moreover, even though AP stack is always under 4GB (a) in Ia32 DXE and (b) with this patch, after transferring to protected mode from X64 DXE, AP stack (in BootServiceData) maybe crashed by OS after Exit Boot Service event.

2016-11-23UefiCpuPkg/MpInitLib: fix feature test for Extended Topology CPUID leafLaszlo Ersek

[...] The "GetApicId" sections in the Ia32 and X64 "MpFuncs.nasm" files do not perform check (b). This causes an actual bug in the following OVMF setup: - Intel W3550 host processor <http://ark.intel.com/products/39720/>, - the QEMU/KVM guest's VCPU model is set to "host", that is, "the CPU visible to the guest should be exactly the same as the host CPU". Under "GetApicId", check (a) passes: the CPUID level of the W3550 is exactly 11 decimal. However, leaf 11 itself is not supported, therefore EDX is set to zero: > If a value entered for CPUID.EAX is less than or equal to the maximum > input value and the leaf is not supported on that processor then 0 is > returned in all the registers. Because we don't check (b), the "GetProcessorNumber" section of the code is reached with an initial APIC ID of 0 in EDX on all of the APs. Given that "GetProcessorNumber" searches the "MP_CPU_EXCHANGE_INFO.CpuInfo[*].InitialApicId" fields for a match, all APs enter ApWakeupFunction() with an identical "NumApsExecuting" parameter. This results in unpredictable guest behavior (crashes, reboots, hangs etc). Reorganize the "GetApicId" section and add the missing check in both assembly files.

2016-11-17UefiCpuPkg/MpInitLib: support 64-bit AP stack addressesLaszlo Ersek
The cached "CPU_INFO_IN_HOB.ApTopOfStack" field currently has type UINT32. This is not ideal because the AP stacks are located within "CpuMpData->Buffer", which is allocated with a plain AllocatePages() call in MpInitLibInitialize(): platform CpuMpPei included PEI RAM > 4GB result -------- ----------------- ------------- ------ Ia32 * n/a good Ia32X64 no n/a BAD Ia32X64 yes n/a good X64 no * BAD X64 yes no good X64 yes yes BAD - If we are on an Ia32X64 or X64 platform that does not include CpuMpPei, then CpuDxe cannot reuse the CPU_INFO_IN_HOB structures preallocated by CpuMpPei (through the CpuInitMpLib GUID HOB), and then AllocatePages() -- invoked first in 64-bit DXE -- could return an address outside of 32-bit address space. - If we are on an X64 platform where the permanent PEI RAM extends above the 32-bit address space, then the same issue can surface even if CpuMpPei is included: even the original allocation of the CPU_INFO_IN_HOB structures, by CpuMpPei, could be satisfied from above 4GB. The original "AP init" branch in "X64/MpFuncs.nasm" correctly considers a 64-bit stack start: the "MP_CPU_EXCHANGE_INFO.StackStart" field has type UINTN, and the code uses QWORD addition and movement to set RSP from it. Adapt the "GetApicId" branch of "X64/MpFuncs.nasm": - change the type of "CPU_INFO_IN_HOB.ApTopOfStack" to UINT64, - remove the explicit truncation to UINT32 in InitializeApData(), - update the "GetNextProcNumber" iteration size to the new size of "CPU_INFO_IN_HOB", - set RSP with a QWORD movement from "CPU_INFO_IN_HOB.ApTopOfStack". Because the same CPU_INFO_IN_HOB structure is used by "Ia32/MpFuncs.nasm", we have to update the "GetNextProcNumber" iteration size there as well. The ESP setting can be preserved as a DWORD movement from the original offset (decimal 12), since our integers are little endian.

2016-11-16UefiCpuPkg/MpInitLib: Program AP stack in fixed addressJeff Fan
Currently, MpInitLib will program AP stack in dynamic address. Each processor will calculate its stack address by adding stack size based on the last stack address. That means AP may have the different stack address everytime it is wakeup by INIT-SIPI-SIPI. When all APs have wakeup to execute AP task, each each has been assigned one stack address. Once the timeout happened on some of APs, BSP will send INIT- SIPI-SIPI to wake up APs. We need to re-assign stack for APs. Based on the current implementation, we might assign one stack address used by other APs. It will cause the unexpected stack overlapped issue. This fix changed the stack assignment policy. We will record the stack address assigned to AP at first time AP wakeup. When AP failed on AP task, BSP could reassigned the same stack for it. Getting initial APIC ID in assembly code could help AP to get saved its stack address.

2016-11-09UefiCpuPkg/MpInitLib: Do not wakeup AP if only one processor supportedJeff Fan
If MaxLogicalProcessorNumber is only 1, we needn't to wake up APs at all and needn't to register callback functions.

2016-08-25UefiCpuPkg/MpInitLib: Don't allocate reset vector in Exit Boot ServiceJeff Fan
In Exit Boot Services callback function, we cannot use allocate memory services because it may change the memory map that has been gotten by OS. This fix is not to allocate reset vector buffer after SaveRestoreFlag is set to TRUE in MpInitExitBootServicesCallback(). Instead AllocateResetVector() will use the previous allocated buffer address and save the contents before copying reset vector code. At the same time, FreeResetVector() will restore original contents after if SaveRestoreFlag is TRUE.

2016-08-25UefiCpuPkg/MpInitLib: Move timeout delay to WakupAp()Jeff Fan
After sending the 1st broadcast INIT-SIPI-SIPI, BSP will collect APs count after one specified timeout delay. However, WakupAp() will restore reset vector immediately after sending 1st broadcast INIT-SIPI-SIPI. Some processors may not complete executing reset vector code. This fix is to move MicroSecondDelay() from CollectProcessorCount() to the place that is after sending 1st broadcast INIT-SIPI-SIPI and before FreeResetVector() in WakupAp().
