* ArmVirtPkg/ArmVirtQemu: Implement ArmMonitorLib for QEMU specificallyArd Biesheuvel2024-06-105-12/+138
| | | | | | | | | | | | | | | | | | | | | Whether SMCCC calls use HVC or SMC generally depends on the exception level that the firmware executes at, but also on whether or not EL2 is implemented. This is almost always known at build time, which is why the default ArmMonitorLib used to model this as a feature PCD. However, on QEMU, things are not that simple. However, SMCCC specifies that the conduit is the same as the one used for PSCI calls (which has been retrofitted into SMCCC when it was defined). Given that QEMU provides this information via the device tree, let's use it to select the conduit, using a special ArmMonitorLib implementation. This also removes the need to set the associated PCD at runtime, given that its updated value will no longer be used. Signed-off-by: Ard Biesheuvel <ardb@kernel.org>
* ArmVirtPkg/PrePi: Enable VFP before calling into C codeArd Biesheuvel2024-06-102-22/+24
| | | | | | | | | | | | When building ArmVirtQemuKernel with CLANGDWARF (which does not require a GCC workaround where -mgeneral-regs-only is needed to ensure -mstrict-align works as expected), the C code invoked from the PrePi startup code may contain instructions that access the FP/SIMD register file. This means that the FP/SIMD must be enabled before making such calls, and this is currently not the case. So fix that, by moving the call to ArmEnableVFP() early into the asm startup code.

| | | | | | | | | | | | | | | | | | | | | Add the RngDxe driver to the build, backed by either RNDR or TRNG, one of which is expected to be available in most cases: - RNDR is implemented by the 'max' CPU that QEMU implements in TCG mode - TRNG is implemented by the KVM hypervisor, which backs QEMU's 'host' CPU Other TCG modes (e.g., the 'cortex-a*' CPUs) implement neither, which should prevent the RngDxe driver from dispatching entirely, resulting in the same situation as before.

* ArmVirtPkg: Use dynamic PCD to set the SMCCC conduitArd Biesheuvel2024-05-246-0/+26
| | | | | | | | | | | | | | | | | | | | On ARM systems, whether SMC or HVC instructions need to be used to issue monitor calls is typically dependent on the exception level, but there are also cases where EL1 might use SMC instructions, so there is no hard and fast rule. For ArmVirtQemu, this does depend strictly on the exception level, so set the default to HVC (for EL1 execution) and override it to SMC when booted at EL2.

* ArmVirtPkg/ArmVirtQemu: always build XIP code with strict alignmentArd Biesheuvel2024-04-221-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The optimization that enabled entry with MMU and caches enabled at EL1 removed the strict alignment requirement for XIP code (roughly, any code that might execute with the MMU and caches off, which means SEC and PEI phase modules but also *all* BASE libraries), on the basis that QEMU can only run guest payloads at EL2 in TCG emulation, which used to ignore alignment violations, and execution at EL1 would always occur with the MMU enabled. This assumption no longer holds: not only does QEMU now enforce strict alignment for memory accesses with device semantics, there are also cases where this code might execute at EL2 under virtualization (i.e., under NV2 nested virtualization) where the strict alignment is required too. The latter case could be optimized too, by enabling VHE and pretending execution is occurring at EL1, which would allow the existing logic for entry with the MMU enabled to be reused. However, this would leave non-VHE CPUs behind. So in summary, strict alignment needs to be enforced for any code that may execute with the MMU off, so drop the override that sets the XIP flags to the empty string.

| | | | | | | | | | | | | | | | | | | | | | | Shim's PE loader uses the EFI memory attributes protocol in a way that results in an immediate crash when invoking the loaded image, unless the base and size of its executable segment are both aligned to 4k. If this is not the case, it will strip the memory allocation of its executable permissions, but fail to add them back for the executable region, resulting in non-executable code. Unfortunately, the PE loader does not even bother invoking the protocol in this case (as it notices the misalignment), making it very hard for system firmware to work around this by attempting to infer the intent of the caller. So let's introduce a QEMU command line option to indicate that the protocol should not be exposed at all, and a PCD to set the default for this option when it is omitted.

All three instances rely on PL011UartLib rather than SerialPortLib so that they can customize the PL011 UART that the debug messages are written to. All three instances direct the debug output to the first such PL011 UART that *differs* from the one specified in the Device Tree's /chosen node's "stdout-path" property. From these, DxeRuntimeDebugLibFdtPL011Uart is identical to DebugLibFdtPL011UartRam, with the addition that UART access is permanently disabled when the containing DXE_RUNTIME_DRIVER module is notified about exiting boot services. The contexts in which these DebugLib instances run are identical to those in which the corresponding SerialPortLib instances run.

* ArmVirtPkg: introduce DebugLibFdtPL011Uart RAM instanceLaszlo Ersek2023-10-264-0/+229

All three instances rely on PL011UartLib rather than SerialPortLib so that they can customize the PL011 UART that the debug messages are written to. All three instances direct the debug output to the first such PL011 UART that *differs* from the one specified in the Device Tree's /chosen node's "stdout-path" property. From these, DebugLibFdtPL011UartRam mirrors FdtPL011SerialPortLib: it relies on the EarlyPL011BaseAddress GUID HOB, and initializes the UART -- a UART different from FdtPL011SerialPortLib's -- only once in the lifetime of the containing module. Suitable for module types that can only execute from RAM (i.e., all types different from SEC, PEI_CORE, PEIM), except DXE_RUNTIME_DRIVER. (Note that OVMF uses a similar set of dedicated DebugLib instances (PlatformDebugLibIoPort) for logging to the (x86-only) isa-debugcon device from various firmware phases.)

* ArmVirtPkg: store separate console and debug PL011 addresses in GUID HOBLaszlo Ersek2023-10-264-18/+62
| | | | | | | | | | | | | | | | | | | | | | PlatformPeiLib produces the EarlyPL011BaseAddress GUID HOB, and FdtPL011SerialPortLib consumes it. Extend the HOB such that it also carry the base address of the PL011 UART meant for DebugLib usage -- namely the first UART that is *not* designated by the /chosen node's "stdout-path" property. Implement this policy in PlatformPeiLib. Note that as far as the SerialPortLib+console UART is concerned, this patch makes no difference. That selection remains consistent with the pre-patch state, and therefore consistent with EarlyFdtPL011SerialPortLib.

* ArmVirtPkg: adjust whitespace in block scope declarationsLaszlo Ersek2023-10-262-28/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | I strongly dislike when *small* local variable declaration changes are muddled by whitespace changes. When that happens, a reviewer can choose from two suboptimal options: display the patch with "git show -b", which creates confusion in *other* parts of the patch, or display the patch with just "git show", which then produces an unjustifiedly large hunk for the sequence of declarations. For avoiding that in subsequent patches, adjust some whitespace in this patch in isolation. Functionally this is a no-op; "git show -b" produces empty output. Note that uncrustify is (of course) unhappy with this patch, but that's fine -- this patch is in the middle of a series, and by the end of the series (which is where uncrustify is run in CI) the whitespace is going to be tight.

* ArmVirtPkg: introduce FdtSerialPortAddressLibLaszlo Ersek2023-10-265-0/+368
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce a new library class + instance for: - collecting serial port base addresses from the device tree, - collecting the /chosen stdout-path serial port base address from the device tree. The logic is loosely based on the following functions: - SerialPortGetBaseAddress() [ArmVirtPkg/Library/FdtPL011SerialPortLib/EarlyFdtPL011SerialPortLib.c] - PlatformPeim() [ArmVirtPkg/Library/PlatformPeiLib/PlatformPeiLib.c] - GetSerialConsolePortAddress() [ArmVirtPkg/Library/Fdt16550SerialPortHookLib/EarlyFdt16550SerialPortHookLib.c] which are going to be converted to clients of the new library later. Copyright notices from those other files are preserved. The new library fixes the following warts, found by reading the existent code: - Neither of the three functions check whether the "reg" property exists. (This may be implicitly checked when they compare the property size to 16.) - GetSerialConsolePortAddress() uses ScanMem8() for locating a colon (":") node path separator in "stdout-path", when AsciiStrStr() could work just as fine. While ScanMem8() is likely faster, "stdout-path" is presumably very short, and ScanMem8() introduces an extra lib class dependency (namely BaseMemoryLib). - If ScanMem8() fails to locate a colon in "stdout-path", then GetSerialConsolePortAddress() re-measures the length of the whole "stdout-path" property. This is conceptually (if not performance-wise) disturbing, because we know the whole size of the "stdout-path" property from the property lookup just before, so we only need to subtract the NUL-terminator for learning the length. - GetSerialConsolePortAddress() does not check if the first (or only) node path inside the "stdout-path" property is empty. (Not a big deal, the subsequent alias resolution should simply fail.) - GetSerialConsolePortAddress() does not verify if the node path retrieved (and potentially alias-resolved) from "stdout-path" can be located in the device tree; it assumes it. - Code is duplicated (of course) between SerialPortGetBaseAddress() and PlatformPeim(), but more surprisingly, all three functions embed the same code for verifying the "status" property of the serial port node, and for checking and reading its "reg" property.

* ArmVirtPkg/FdtPL011SerialPortLib: initialize implicitlyLaszlo Ersek2023-10-072-34/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | FdtPL011SerialPortLib claims that it's usable from the DXE_CORE. That's not correct: the DXE_CORE calls DEBUG() and ASSERT() before it calls ProcessLibraryConstructorList(). Via the BaseDebugLibSerialPort instance, those DEBUG() and ASSERT() calls result in SerialPortWrite() calls, before ProcessLibraryConstructorList() called either our constructor FdtPL011SerialPortLibInitialize(), or BaseDebugLibSerialPortConstructor(). (And even if the DXE_CORE called the latter function early enough, it would just invoke our SerialPortInitialize() function -- which does nothing.) This means that the earliest DXE_CORE debug messages are lost. Rename FdtPL011SerialPortLibInitialize() to SerialPortInitialize(), so that the same initialization occur through the constructor and the public SerialPortInitialize() library API. Turn SerialPortInitialize() calls after the first one into no-ops. Our SerialPortLib APIs already use (mSerialBaseAddress != 0) to track initialization. Rework those checks to actually initialize the library if that hasn't happened yet. The following new lines appear in the log: > CoreInitializeMemoryServices: > BaseAddress - 0x48000000 Length - 0xF8000000 MinimalMemorySizeNeeded - 0x38C8000 > InstallProtocolInterface: [EfiLoadedImageProtocol] 46EFC3E0 > ProtectUefiImageCommon - 0x46EFC3E0 > - 0x0000000046EB2000 - 0x0000000000068000 (0x46EB2000 is the load address of the DXE Core.)

| | | | | | | | | | | | | | | | | | | | | | | | BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4504 The BaseRngLibTimerLib allows to generate number based on a timer. This mechanism allows to have a basic non-secure implementation for non-production platforms. To bind and identify Random Number Generators implementations with a GUID, an unsafe GUID should be added. This GUID cannot be added to the MdePkg unless it is also added to a specification. To keep the MdePkg self-contained, copy the BaseRngLibTimerLib to the MdeModulePkg. This will allow to define an unsafe Rng GUID in a later patch in the MdeModulePkg. The MdePkg implementation will be removed later. This allows to give some time to platform owners to switch to the MdeModulePkg implementation.

| | | | | | | | | | | | | | | | | | | | | Currently, unlike OVMF, ArmVirtQemu does not display any graphics, only the QEMU monitor. Graphics are helpful to confirm booting into an OS is successful, interacting with the EFI shell while getting separate logging messages, etc. This patch adds the QEMU parameters to launch a graphical window and add a USB keyboard and mouse, which is modeled as a tablet as it tracks better in QEMU than a generic mouse. virtio-gpu-pci is chosen as the graphics device as it is recommended by QEMU for the ARM virtual platform. The graphics and USB input devices will only be added to QEMU when QEMU_HEADLESS == FALSE, so CI builds will not attempt to use the graphics and if a user does not want graphics, they can add QEMU_HEADLESS=TRUE to the build cmdline.
