* OvmfPkg: remove USE_OLD_PCI_HOST build optionLaszlo Ersek2016-04-071-4/+0
| | | | | | | | | | | | | | | | | | It's been a month since the following commits appeared in the repo: 4014885ffdfa8 OvmfPkg: switch to MdeModulePkg/Bus/Pci/PciHostBridgeDxe c47ed6fcb5e60 OvmfPkg: match PCI config access to machine type (if not USE_OLD_PCI_HOST) in which we introduced the USE_OLD_PCI_HOST fallback, and made other work depend on it. I have not heard of any problems (primarily from the vfio-users group that uses Gerd's daily / hourly OVMF builds), so it's time to drop the fallback.

* OvmfPkg: LockBox: use SMM stack with -D SMM_REQUIRELaszlo Ersek2015-11-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During DXE, drivers save data in the LockBox. A save operation is layered as follows: - The unprivileged driver wishing to store data in the LockBox links against the "MdeModulePkg/Library/SmmLockBoxLib/SmmLockBoxDxeLib.inf" library instance. The library allows the unprivileged driver to format requests for the privileged SMM LockBox driver (see below), and to parse responses. We apply this resolution for DXE_DRIVER modules. - The privileged SMM LockBox driver is built from "MdeModulePkg/Universal/LockBox/SmmLockBox/SmmLockBox.inf". This driver has module type DXE_SMM_DRIVER and can access SMRAM. The driver delegates command parsing and response formatting to "MdeModulePkg/Library/SmmLockBoxLib/SmmLockBoxSmmLib.inf". Therefore we include this DXE_SMM_DRIVER in the build, and apply said resolution specifically to it. (Including the driver requires us to resolve a few of other library classes for DXE_SMM_DRIVER modules.) - In PEI, the S3 Resume PEIM (UefiCpuPkg/Universal/Acpi/S3Resume2Pei) retrieves data from the LockBox. It is capable of searching SMRAM itself. We resolve LockBoxLib to "MdeModulePkg/Library/SmmLockBoxLib/SmmLockBoxPeiLib.inf" specifically for this one PEIM.

* OvmfPkg: pull in the SMM IPL and SMM coreLaszlo Ersek2015-11-301-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | "MdeModulePkg/Core/PiSmmCore/PiSmmIpl.inf" (a DXE_RUNTIME_DRIVER) implements the SMM Initial Program Loader. It produces EFI_SMM_BASE2_PROTOCOL and EFI_SMM_COMMUNICATION_PROTOCOL, relying on: - EFI_SMM_ACCESS2_PROTOCOL (provided by OvmfPkg/SmmAccess/SmmAccess2Dxe.inf), - EFI_SMM_CONTROL2_PROTOCOL (provided by OvmfPkg/SmmControl2Dxe/SmmControl2Dxe.inf). (The SMM IPL also depends on EFI_SMM_CONFIGURATION_PROTOCOL_GUID, but this dependency is not enforced in the entry point. A protocol notify callback is registered instead, hence we can delay providing that protocol via the PiSmmCpuDxeSmm driver that is (to be) imported from UefiCpuPkg/.) The SMM IPL loads the SMM core into SMRAM and executes it from there. Therefore we add the SMM core to the build as well. For the SMM core, a number of library classes need to be resolved. Furthermore, each FDF file must provide the GenFds.py BaseTools utility with a build rule for SMM_CORE; we copy the DXE_CORE's rule.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "MdeModulePkg/Library/SmmLockBoxLib/SmmLockBoxPeiLib.inf" is the LockBoxLib instance with SMRAM access for the PEI phase. Said library instance must, and can, access the LockBox data in SMRAM directly if it is invoked before SMBASE relocation / SMI handler installation. In that case, it only needs PEI_SMM_ACCESS_PPI from the platform, and it doesn't depend on EFI_PEI_SMM_COMMUNICATION_PPI. OVMF satisfies the description in SVN r18823 ("MdeModulePkg: SmmLockBoxPeiLib: work without EFI_PEI_SMM_COMMUNICATION_PPI"): in OVMF, only S3Resume2Pei links against SmmLockBoxPeiLib. Therefore, introduce a PEIM that produces the PEI_SMM_ACCESS_PPI interface, enabling SmmLockBoxPeiLib to work; we can omit including "UefiCpuPkg/PiSmmCommunication/PiSmmCommunicationPei.inf". The load / installation order of S3Resume2Pei and SmmAccessPei is indifferent. SmmAccessPei produces the gEfiAcpiVariableGuid HOB during its installation (which happens during PEI), but S3Resume2Pei accesses the HOB only when the DXE IPL calls its S3RestoreConfig2 PPI member, as last act of PEI. MCH_SMRAM_D_LCK and MCH_ESMRAMC_T_EN are masked out the way they are, in SmmAccessPeiEntryPoint() and SmramAccessOpen() respectively, in order to prevent VS20xx from warning about the (otherwise fully intentional) truncation in the UINT8 casts.

* OvmfPkg: Sec: assert the build-time calculated end of the scratch bufferLaszlo Ersek2015-11-301-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | The DecompressMemFvs() function in "OvmfPkg/Sec/SecMain.c" uses more memory, temporarily, than what PEIFV and DXEFV will ultimately need. First, it uses an output buffer for decompression, second, the decompression itself needs a scratch buffer (and this scratch buffer is the highest area that SEC uses). DecompressMemFvs() used to be called on normal boots only (ie. not on S3 resume), which is why the decompression output buffer and the scratch buffer were allowed to scribble over RAM. However, we'll soon start to worry during S3 resume that the runtime OS might tamper with the pre-decompressed PEIFV, and we'll decompress the firmware volumes on S3 resume too, from pristine flash. For this we'll need to know the end of the scratch buffer in advance, so we can prepare a non-malicious OS for it. Calculate the end of the scratch buffer statically in the FDF files, and assert in DecompressMemFvs() that the runtime decompression will match it.

Here is the example of the dnsmasq config: interface=<tap interface> dhcp-range=192.168.111.100,192.168.111.120,12h dhcp-option=60,"HTTPClient" dhcp-boot="http://<tap ip>/<efi file>" It's similar to the PXE server settings except the tftp function is disabled, the option 60 must be "HTTPClient", and the boot uri is a http url.

* OvmfPkg: Fix GCC49 build hang in PeiCoreRuiyu Ni2015-07-091-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PeiCore hang when loads a PEIM whose section alignment requirement is 0x40 but the actual base address is 0x20 aligned. The issue is caused by the following facts, in order: 1. GCC49 requires the section alignment of .data to be 0x40. So a new link script gcc4.9-ld-script was added for GCC49 to specify the 0x40 alignment. 2. GenFw tool was enhanced to sync ELF's section alignment to PE header. Before the enhancement, the section alignment of converted PE image always equals to 0x20. If only with #1 change, GCC49 build image won't hang in PeiCore because the converted PE image still claims 0x20 section alignment which is aligned to the align setting set in FDF file. But later with #2 change, the converted PE image starts to claims 0x40 section alignment, while build tool still puts the PEIM in 0x20 aligned address, resulting the PeCoffLoaderLoadImage() reports IMAGE_ERROR_INVALID_SECTION_ALIGNMENT error.

* OvmfPkg: include XHCI driverLaszlo Ersek2015-03-161-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | QEMU commit aa685789 ("xhci: generate a Transfer Event for each Transfer TRB with the IOC bit set") fixed an emulation problem in QEMU; we can now drive that host controller with edk2's XhciDxe. Include it in OvmfPkg, as XHCI emulation is reportedly more virtualization-friendly than EHCI, consuming less CPU. The driver can be tested with the following QEMU command line options: -device nec-usb-xhci -device usb-kbd This patch should not regress existing QEMU command lines (ie. trigger an ASSERT() in XhciDxe that fails on pre-aa685789 QEMU) because QEMU's "-device nec-usb-xhci" has never before resulted in USB devices that worked with edk2 firmware builds, hence users have never had a reason to add that option. Now that they learn about XHCI support in OVMF by reading this commit message, they (or their packagers) will also know to update qemu to aa685789 or later (in practice that means the upcoming 2.3 release), at least if they want to use '-device nec-usb-xhci' with edk2, for the first time ever.

BaseExtractGuidedSectionLib is a library instance (of type BASE) for this library class. It has no constructor function. LzmaCustomDecompressLib is a compatible decompressor module (of type BASE). Its section type GUID is gLzmaCustomDecompressGuid == EE4E5898-3914-4259-9D6E-DC7BD79403CF When OVMF's SecMain module starts, the LzmaCustomDecompressLib constructor function is executed, which registers its LZMA decompressor with the above GUID, by calling into BaseExtractGuidedSectionLib: LzmaDecompressLibConstructor() [GuidedSectionExtraction.c] ExtractGuidedSectionRegisterHandlers() [BaseExtractGuidedSectionLib.c] GetExtractGuidedSectionHandlerInfo() PcdGet64 (PcdGuidedExtractHandlerTableAddress) -- NOTE THIS Later, during a normal (non-S3) boot, SecMain utilizes this decompressor to get information about, and to decompress, sections of the OVMF firmware image: SecCoreStartupWithStack() [OvmfPkg/Sec/SecMain.c] SecStartupPhase2() FindAndReportEntryPoints() FindPeiCoreImageBase() DecompressMemFvs() ExtractGuidedSectionGetInfo() [BaseExtractGuidedSectionLib.c] ExtractGuidedSectionDecode() [BaseExtractGuidedSectionLib.c] Notably, only the extraction depends on full-config-boot; the registration of LzmaCustomDecompressLib occurs unconditionally in the SecMain EFI binary, triggered by the library constructor function. This is where the bug happens. BaseExtractGuidedSectionLib maintains the table of GUIDed decompressors (section handlers) at a fixed memory location; selected by PcdGuidedExtractHandlerTableAddress (declared in MdePkg.dec). The default value of this PCD is 0x1000000 (16 MB). This causes SecMain to corrupt guest OS memory during S3, leading to random crashes.

The "EGSI" signature corresponds to EXTRACT_HANDLER_INFO_SIGNATURE declared in MdePkg/Library/BaseExtractGuidedSectionLib/BaseExtractGuidedSectionLib.c. Additionally, the gLzmaCustomDecompressGuid (quoted above) is visible at guest-phys offset 0x1000020. Fix the problem as follows: - Carve out 4KB from the 36KB gap that we currently have between PcdOvmfLockBoxStorageBase + PcdOvmfLockBoxStorageSize == 8220 KB and PcdOvmfSecPeiTempRamBase == 8256 KB. - Point PcdGuidedExtractHandlerTableAddress to 8220 KB (0x00807000). - Cover the area with an EfiACPIMemoryNVS type memalloc HOB, if S3 is supported and we're not currently resuming. The 4KB size that we pick is an upper estimate for BaseExtractGuidedSectionLib's internal storage size. The latter is calculated as follows (see GetExtractGuidedSectionHandlerInfo()): sizeof(EXTRACT_GUIDED_SECTION_HANDLER_INFO) + // 32 PcdMaximumGuidedExtractHandler * ( sizeof(GUID) + // 16 sizeof(EXTRACT_GUIDED_SECTION_DECODE_HANDLER) + // 8 sizeof(EXTRACT_GUIDED_SECTION_GET_INFO_HANDLER) // 8 ) OVMF sets PcdMaximumGuidedExtractHandler to 16 decimal (which is the MdePkg default too), yielding 32 + 16 * (16 + 8 + 8) == 544 bytes. Regarding the lifecycle of the new area: (a) when and how it is initialized after first boot of the VM The library linked into SecMain finds that the area lacks the signature. It initializes the signature, plus the rest of the structure. This is independent of S3 support. Consumption of the area is also limited to SEC (but consumption does depend on full-config-boot). (b) how it is protected from memory allocations during DXE It is not, in the general case; and we don't need to. Nothing else links against BaseExtractGuidedSectionLib; it's OK if DXE overwrites the area. (c) how it is protected from the OS When S3 is enabled, we cover it with AcpiNVS in InitializeRamRegions(). When S3 is not supported, the range is not protected. (d) how it is accessed on the S3 resume path Examined by the library linked into SecMain. Registrations update the table in-place (based on GUID matches). (e) how it is accessed on the warm reset path If S3 is enabled, then the OS won't damage the table (due to (c)), hence see (d). If S3 is unsupported, then the OS may or may not overwrite the signature. (It likely will.) This is identical to the pre-patch status.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This driver (from "MdeModulePkg/Universal/Acpi/BootScriptExecutorDxe/BootScriptExecutorDxe.inf") is first loaded normally during DXE. When the EFI_DXE_SMM_READY_TO_LOCK_PROTOCOL is installed by any DXE driver (purely as a form of notification), the driver reloads itself to reserved memory. During S3 Resume / PEI, the driver image is executed from there. In order to access the boot script saved during S3 Suspend, LockBox access is needed. The boot script is transferred internal to PiDxeS3BootScriptLib: Both S3SaveStateDxe and BootScriptExecutorDxe are statically linked against PiDxeS3BootScriptLib. Whichever is loaded first (during normal boot, in the DXE phase), allocates the root storage for the script. The address is then passed between the PiDxeS3BootScriptLib instances living in the two separate drivers thru the dynamic PcdS3BootScriptTablePrivateDataPtr PCD.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "MdeModulePkg/Universal/Acpi/S3SaveStateDxe/S3SaveStateDxe.inf" produces the EFI_S3_SAVE_STATE_PROTOCOL which allows creation and saving of an S3 Boot Script, to be replayed in PEI during S3 Resume. The script contains opcodes and opcode arguments to configure CPU, PCI and IO resources. S3SaveStateDxe relies on the S3BootScriptLib library. The Null implementation is not useful for actually saving the boot script, we need the PiDxeS3BootScriptLib instance. The PiDxeS3BootScriptLib library instance depends on LockBoxLib, implemented for OVMF in one of the previous patches. PiDxeS3BootScriptLib also depends on SmbusLib. For now we opt for the Null instance of the latter. It means that SMBus commands in the boot script will have no effect when interpreted during S3 Resume. This should be fine for OvmfPkg and QEMU.

| | | | | | | | | | | | | | | | | | | | | | | | The S3 suspend/resume infrastructure depends on the LockBox library class. The edk2 tree currently contains Null and SMM instances. The Null instance is useless, and the SMM instance would require SMM emulation by including the SMM core and adding several new drivers, which is deemed too complex. Hence add a simple LockBoxLib instance for OVMF. jordan.l.justen@intel.com: * use PCDs instead of EmuNvramLib - clear memory in PlatformPei on non S3 boots * allocate NVS memory and store a pointer to that memory - reduces memory use at fixed locations Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Laszlo Ersek <lersek@redhat.com> Reviewed-by: Jordan Justen <jordan.l.justen@intel.com> Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Jordan Justen <jordan.l.justen@intel.com> Reviewed-by: Laszlo Ersek <lersek@redhat.com> git-svn-id: https://svn.code.sf.net/p/edk2/code/trunk/edk2@15301 6f19259b-4bc3-4df7-8a09-765794883524
