| | | | | | | | | | | | | | | | | | | | The TFTP command was converted from a NULL class library instance to a dynamic shell command in commit 0961002352e9. The ShellLib and FileHandleLib resolutions are moved from [LibraryClasses.common.UEFI_APPLICATION] to [LibraryClasses.common] because dynamic shell commands are implemented as DXE_DRIVER modules. PcdShellLibAutoInitialize must be set to FALSE for both the shell app itself and the dynamic shell command modules.

| | | | | | | | | | | | | | | | | | | The PrePi code we inherited from ArmPlatformPkg contains a rather obscure optimization, where entry points of the PE/COFF and LZMA handling routines are recorded in special HOBs, allowing DXE core to call into that code directly rather than carry its own copy of these libraries.

* ArmVirtPkg: create QemuVirtMemInfoLib version for ArmVirtQemuArd Biesheuvel2017-11-233-0/+167
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The QemuVirtMemInfoLib ArmVirtMemInfoLib implementation created for ArmVirtQemuKernel does exactly what we need for ArmVirtQemu, the only difference being that the latter is PrePeiCore based, and so it uses a different method to ensure that PcdSystemMemorySize is set when ArmVirtGetMemoryMap() is called. On ArmVirtQemu, we currently abuse the implied ordering guarantees provided by ArmPlatformLib, by implementing this as follows: ArmPlatformPkg/MemoryInitPei/MemoryInitPeim.inf [ArmVirtPkg/ArmVirtQemu.dsc] InitializeMemory() [ArmPlatformPkg/MemoryInitPei/MemoryInitPeim.c] ArmPlatformInitializeSystemMemory() [ArmVirtPkg/Library/ArmVirtPlatformLib/Virt.c] // // set PcdSystemMemorySize from the DT // MemoryPeim() [ArmVirtPkg/Library/ArmVirtMemoryInitPeiLib/ArmVirtMemoryInitPeiLib.c] InitMmu() [ArmVirtPkg/Library/ArmVirtMemoryInitPeiLib/ArmVirtMemoryInitPeiLib.c] ArmPlatformGetVirtualMemoryMap() [ArmVirtPkg/Library/ArmVirtPlatformLib/VirtMem.c] // // consume PcdSystemMemorySize // Given that we are trying to get rid of ArmPlatformLib, or at least remove some of these API functions that are never used for their original purpose by any platforms, we need to move the PCD assignment elsewhere. So create a PEIM-only version of QemuVirtMemInfoLib especially for ArmVirtQemu, and add the PCD assignment code to its constructor.

* ArmVirtPkg/ArmVirtQemu: use non-accelerated CopyMem for VariableRuntimeDxeArd Biesheuvel2017-11-162-0/+4
| | | | | | | | | | | | | | | | | | | | | | | The VariableRuntimeDxe driver may use CopyMem () on NOR flash regions, assuming such regions always have full memory semantics. Given that those regions cannot be mapped as ordinary memory on ARM (due to the fact that the NOR flash requires device semantics while in write mode) this prevents us from using BaseMemoryLibOptDxe in VariableRuntimeDxe, since it may use unaligned accesses and/or DC ZVA instructions, both of which are incompatible with mappings using device semantics. Note that there is no way we can work around this by changing the mapping type between 'memory' and 'device' when switching from read to write mode and back, because the runtime mapping is created by the OS, and cannot be changed at will. So let's just switch to the unaccelerated version of BaseMemoryLib which does not have the same problem.

* ArmVirtPkg: remove QemuVideoDxe from ArmVirtQemu and ArmVirtQemuKernelArd Biesheuvel2017-08-243-5/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | One of the reasons for introducing virtio-gpu support to OvmfPkg and ArmVirtpkg was the fact that under KVM virtualization on ARM, the legacy VGA cannot be used reliably. This is due to an implementation detail of QEMU+KVM, which remaps cached host memory into the guest address space as a framebuffer behind a PCI BAR. Given that the purpose of a memory mapped framebuffer is its side effects, such BARs should never be mapped cacheable in the guest, and the mismatched attributes between host and guest result in a loss of coherency, visible as corruption in the framebuffer image. This issue does not occur under TCG emulation, nor did we expect it to actually bring down the guest under KVM, and so it was deemed harmless to keep support for the VGA device as well. However, as it turns out, the fact that the framebuffer BAR is mapped using device semantics by default may result in unalignment faults when we use the ordinary string copy routines on the contents. In theory, we could work around this by remapping the BAR as write combining, but it appears the generic PCI bus driver does not actually implement this. So let's remove the QemuVideoDxe driver altogether. This may result in loss of functionality for use cases that rely on the framebuffer to be directly addressable (such as EFIFB), but given that this never worked reliably under KVM in the first place, let's not let that stop us from dropping support for it.

* ArmVirtPkg/FdtPL011SerialPortLib: call PL011UartLib in all SerialPortLib APIsLaszlo Ersek2017-08-171-3/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the SerialDxe change in commit 4cf3f37c87ba ("MdeModulePkg SerialDxe: Process timeout consistently in SerialRead", 2017-07-18), setting EFI_SERIAL_INPUT_BUFFER_EMPTY in the "Control" output parameter, in the GetControl() SerialPortLib function, is no longer a "small optimization". Namely, due to the SerialDxe change, the GetOneKeyFromSerial() call in TerminalDxe's TerminalConInTimerHandler() can take very long if the input queue is empty, even if GetOneKeyFromSerial()'s return value causes the loop to be exited right after, in the first iteration. This issue causes a boot hang in ArmVirtQemu: with the input queue empty, TerminalConInTimerHandler() takes so long to return that, by the time it returns, there's another execution queued already (due to the associated timer event being signaled meanwhile). The boot process is stuck in the timer event handler. Therefore even the first GetOneKeyFromSerial() iteration must be prevented in TerminalConInTimerHandler() if the input queue is empty, and that requires implementing GetControl() for real. Implement the SetAttributes(), SetControl() and GetControl() APIs (of SerialPortExtLib origin) in FdtPL011SerialPortLib with calls to matching PL011UartLib functions. This follows the example of "ArmPlatformPkg/Library/PL011SerialPortLib" and also matches Star's original idea under [1]. The patch can be considered a continuation of commit ad7f6bc2e116 ("ArmVirtPkg: Use SerialDxe in MdeModulePkg instead of EmbeddedPkg", 2015-11-26), based on the mailing list threads [1] [2] [3].

As before, warm reset and platform specific reset are mapped onto cold reset (which is the only thing PSCI implements, at least the version we depend on). The new library function EnterS3WithImmediateWake() is left unimplemented, as permitted by the ResetSystemLib library class.

* ArmVirtPkg/ArmVirtQemuKernel: increase slack space for DTBArd Biesheuvel2017-04-041-6/+6
| | | | | | | | | | | | | | | | | | | | The relocatable build of ArmVirtQemuKernel is designed to be executed from RAM, and contains some scratch memory at the start of the image to use as a stack very early on, and to preserve the DTB image received from QEMU while it discovers and initializes memory. It turns out that 8 KB is a bit on the small side here, especially when executing with secure world emulation enabled, in which case there are additional nodes present. So increase the slack space to 32 KB. While at it, remove a stale Xen reference that was copy/pasted when this file was created.

So check whether a 'status' property is present, and if so, ignore the node if the status is not 'okay'.

* ArmVirtPkg/PlatformHasAcpiDtDxe: allow guest level ACPI disable overrideArd Biesheuvel2017-03-314-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | In general, we should not present two separate (and inevitably different) hardware descriptions to the OS, in the form of ACPI tables and a device tree blob. For this reason, we recently added the logic to ArmVirtQemu to only expose the ACPI 2.0 entry point if no DT binary is being passed, and vice versa. However, this is arguably a regression for those who relied on DT descriptions being available, even if the former behavior can be restored by passing the -no-acpi switch to QEMU. So allow a secret handshake with the UEFI Shell, to set a variable that will result in ACPI to be disabled on subsequent boots even if -no-acpi was not passed on the QEMU command line. setvar -nv -bs -guid 50bea1e5-a2c5-46e9-9b3a-59596516b00a ForceNoAcpi =01 To delete the variable and revert to the old situation, simply omit the value after the = setvar -nv -bs -guid 50bea1e5-a2c5-46e9-9b3a-59596516b00a ForceNoAcpi = Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Reviewed-by: Laszlo Ersek <lersek@redhat.com> Tested-by: Marc Zyngier <marc.zyngier@arm.com> Acked-by: Marc Zyngier <marc.zyngier@arm.com>
