2016-09-02MdeModulePkg/EbcDxe AARCH64: simplify interpreter entry point thunksArd Biesheuvel
The prototypes of EbcInterpret() and ExecuteEbcImageEntryPoint() are private to the AARCH64 implementation of EbcDxe, so we can shuffle the arguments around a bit and make the assembler thunking glue a lot simpler. For ExecuteEbcImageEntryPoint(), this involves passing the EntryPoint argument as the third parameter, rather than the first, which allows us to do a tail call. For EbcInterpret(), instead of copying each argument beyond #8 from one native stack frame to the next (before another copy is made into the VM stack), pass a pointer to the argument stack.

2016-09-02MdeModulePkg/EbcDxe AARCH64: use tail call for EBC to native thunkArd Biesheuvel
Instead of pessimistically copying at least 64 bytes from the VM stack to the native stack, and popping off the register arguments again before doing the native call, try to avoid touching the stack completely if the VM stack frame is <= 64 bytes. Also, if the stack frame does exceed 64 bytes, there is no need to copy the first 64 bytes, since we are passing those in registers anyway.

2016-09-02MdeModulePkg/EbcDxe AARCH64: use a fixed size thunk structureArd Biesheuvel
The thunk generation is needlessly complex, given that it attempts to deal with variable length instructions, which don't exist on AArch64. So replace it with a simple template coded in assembler, with a matching struct definition in C. That way, we can create and manipulate the thunks easily without looping over the instructions looking for 'magic' numbers. Also, use x16 rather than x9, since it is the architectural register to use for thunks/veneers.

2016-08-18MdeModulePkg: Fix potential failure if UseDefaultAddress configuredJiaxin Wu
IpSb->Reconfig should not be set to TRUE to focal the reconfiguration during the policy changes from Static to DHCP. It's redundancy because the default router table and default addresses have been freed ahead ( Detailed see Ip4Config2OnPolicyChanged() function). Otherwise, the potential failure will appear if UseDefaultAddress configured. Reproduce steps see below: #1. Set policy to DHCP. #2. If DHCP process is not complete yet, then run one APP to invoke UDP4 Configure with "UseDefaultAddress = TRUE" (loop to call UDP4 Configure until Ip4Mode.IsConfigured changes to TRUE). #3. Even DHCP succeed but Ip4Mode.IsConfigured flag never set to TRUE Concrete analysis is as follows: In #1, the policy will be set to DHCP, and then Ip4Config2OnPolicyChanged() will be called. In this function, if "IpSb->Reconfig" flag is set to TRUE, the original "IpSb->DefaultInterface" will be abandoned/freed once the DHCP process finished. In #2, UDP4 Configure with "UseDefaultAddress = TRUE" is called, that means the default interface (IpSb->DefaultInterface) will be selected as current instance's interface. In #3, when DHCP process finished, the original DefaultInterface will be abandoned/freed because "IpSb->Reconfig" flag is true. Meanwhile, one new interface is assigned to "IpSb->DefaultInterface". This new interface is different to the original one assigned to the UDP4 Configured instance. So, even DHCP process succeed, the up caller will never have the chance to get it's truly status.

2016-07-13MdeModulePkg/PciBusDxe: recognize hotplug-capable PCIe portsLaszlo Ersek
Section 7.8.2 of the PCI Express specification (r4.0 v0.3), entitled "PCI Express Capabilities Register (Offset 02h)", and section 7.8.9 "Slot Capabilities Register (Offset 14h)" of the same, describe the conditions when a PCIe port should be considered "supporting hotplug": - it should be a root complex port or a switch downstream port, and - it should have the "Slot Implemented" bit set in the Express Capabilities Register, and - it should have the "Hot-Plug Capable" bit set in the Slot Capabilities Register. The first two sub-conditions are already implemented in at least two open source projects I could find: - in SeaBIOS by Marcel Apfelbaum: "hw/pci: reserve IO and mem for pci express downstream ports with no devices attached" <https://code.coreboot.org/p/seabios/source/commit/3aa31d7d6375>, - in edk2 itself, in the implementation of the "PCI" UEFI Shell command: see the "PcieExplainTypeSlot" case label in function PciExplainPciExpress(), file "ShellPkg/Library/UefiShellDebug1CommandsLib/Pci.c". PciBusDxe recognizes such PCIe ports as bridges, but it doesn't realize they support hotplug. In turn PciBusDxe omits getting any resource padding information from the platform's EFI_PCI_HOT_PLUG_INIT_PROTOCOL for these bridges: GatherPpbInfo() [PciEnumeratorSupport.c] GetResourcePaddingPpb() [PciResourceSupport.c] GetResourcePaddingForHpb() [PciHotPlugSupport.c] IsPciHotPlugBus() [PciHotPlugSupport.c] // // returns FALSE // // // the following is not reached: // gPciHotPlugInit->GetResourcePadding() Implement a function called SupportsPcieHotplug() for identifying such ports, and call it from IsPciHotPlugBus() (after the call to IsSHPC()).
