2015-02-25ArmVirtualizationPkg: PlatformIntelBdsLib: detect consoles dynamicallyLaszlo Ersek
Detect the video displays dynamically, and add them to the console and error output variables. Add a short-form, "wild card" USB_CLASS_DEVICE_PATH to the console input variable, which causes the USB keyboard to be handled automatically. Add the fixed location serial console to all of the console input, console output, and error output variables. This patch enables QEMU users to drop "addr=..." PCI address specifications from the -device options (or to use whatever addresses they like). For example, the following works: -device VGA \ \ -device ich9-usb-ehci1,multifunction=on,id=ehci \ -device ich9-usb-uhci1,multifunction=on,masterbus=ehci.0,firstport=0 \ -device ich9-usb-uhci2,multifunction=on,masterbus=ehci.0,firstport=2 \ -device ich9-usb-uhci3,multifunction=on,masterbus=ehci.0,firstport=4 \ -device usb-kbd,bus=ehci.0 Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Laszlo Ersek <lersek@redhat.com> Acked-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Tested-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Reviewed-by: Olivier Martin <olivier.martin@arm.com> git-svn-id: https://svn.code.sf.net/p/edk2/code/trunk/edk2@16924 6f19259b-4bc3-4df7-8a09-765794883524
2015-02-25ArmVirtualizationPkg: PlatformIntelBdsLib: remove ties to ARM BDSLaszlo Ersek
In this patch we remove all dependencies on ARM BDS libraries. We also remove empty and/or unneeded functions, includes, etc. PlatformIntelBdsLib "goes back to basics" temporarily -- there are no consoles configured, and it's practically not possible to interact with the user interface. Bisection remains available in the sense that "ArmVirtualizationQemu.dsc" continues to build and should boot preexistent boot options, but user interaction does regress temporarily. The reason for this is that it's preferable to keep this patch and the next one separate for readability's sake -- they amount to a rewrite from scratch.

2015-02-23ArmVirtualizationPkg: PlatformIntelBdsLib: fix multiconsole setupLaszlo Ersek
In the following call chain: PlatformBdsPolicyBehavior() PlatformBdsConnectConsole() InitializeConsolePipe() x 3 BdsConnectDevicePath() [ArmPkg/Library/BdsLib/BdsFilePath.c] the three InitializeConsolePipe() function calls pass through - (&gST->ConsoleOutHandle, &gST->ConOut), - (&gST->ConsoleInHandle, &gST->ConIn), - (&gST->StandardErrorHandle, &gST->StdErr) to BdsConnectDevicePath(), in ArmPkg's BdsLib. At least when more than one console device paths are specified in the ConIn / ConOut / ErrOut variables, the above resuls in: - unchanged protocol interfaces (ConOut, ConIn, StdErr) in the system table (because ConSplitterDxe installs its non-NULL interfaces first), - but, changed handles in the system table. This effectively separates the handle fields in the system table from the protocol interfaces in the same that should always be associated with the handles. The end result is that clients using the handles break (splitting / multiplexing doesn't work for them), while clients directly using the protocol interfaces work. Therefore, do not attempt to connect consoles separately. ConSplitterDxe is dispatched before PlatformBdsPolicyBehavior() is called (the latter happens in the BDS phase), and ConSplitterDxe installs virtual handles and protocol interfaces for input / output / error. BdsLibConnectAll() covers all devices, including consoles; as those consoles are connected, ConPlatformDxe and ConSplitterDxe pick them up nicely as "slaves". We just need to make sure that the variables are set first, for the variables -> ConPlatformDxe -> ConSplitterDxe dependency chain.

2015-02-23ArmVirtualizationPkg: PlatformIntelBdsLib: kernel boot should provide ACPILaszlo Ersek
If there is a PCI host, then PCI enumeration (which happens inside BdsLibConnectAll()) blocks ACPI table installation (correctly). Make sure we install ACPI tables before trying to direct-boot a QEMU kernel.

2015-01-02ArmVirtualizationPkg: Intel BDS: load EFI-stubbed Linux kernel from fw_cfgLaszlo Ersek
A number of tools depend on passing the kernel image, the initial ramdisk, and the kernel command line to the guest on the QEMU command line (options -kernel, -initrd, -append, respectively). At the moment, these QEMU options work, but the guest kernel loaded this way is launched by a minimal binary firmware that is dynamically composed by QEMU. As a consequence, such a kernel has no UEFI environment. This patch enables -kernel, -initrd, -append to work on top of the ArmVirtualizationQemu firmware build. The approach it takes is different from how the same functionality is implemented in OvmfPkg. OvmfPkg contains a full-fledged Linux boot loader (see "OvmfPkg/Library/PlatformBdsLib/QemuKernel.c" and "OvmfPkg/Library/LoadLinuxLib/"). OVMF's LoadLinuxLib sets up the required kernel environment in a sophisticated way (including x86-specific artifacts like the GDT), calls ExitBootServices() itself (for legacy kernels without EFI handover protocol), and jumps to the kernel (using x86 assembly). In ArmVirtualizationPkg's PlatformIntelBdsLib, we require the kernel being loaded to have an EFI stub -- that is, to be a genuine UEFI application. (The EFI stub is not an additional burden for guest kernels -- the EFI stub is a hard requirement anyway because it needs to process the DTB heavily: - it removes memory nodes, - it removes memreserve entries, - it adds UEFI properties to the "chosen" node, - it calculates and installs virt-to-phys mappings with SetVirtualAddressMap() in a way that enables kexec [planned]. Kudos to Ard Biesheuvel for summarizing the above.) An EFI-stubbed Linux guest kernel can be loaded with plain gBS->LoadImage(). The EFI stub will look up its own EFI_LOADED_IMAGE_DEVICE_PATH_PROTOCOL instance (ie. the device path where it has been loaded from), and it will locate the initial ramdisk named by the "initrd" command line parameter as a *sibling file* on the same device. The initrd file is then loaded using the EFI_SIMPLE_FILE_SYSTEM_PROTOCOL. This approach enables the EFI stub to load the initial ramdisk from normal EFI System Partitions, from remote PXE/TFTP directories -- and it enables us to provide the initrd from memory as well. In this patch: - We download the kernel image, the initrd image, and the kernel command line, using QEMU's fw_cfg interface. - We create a read-only EFI_SIMPLE_FILE_SYSTEM_PROTOCOL instance that has just a root directory, with the three downloaded files in it. - The handle that carries the simple file system has a single-node VenHw(...) device path (not counting the terminator node). - We load the EFI-stubbed kernel (which is a UEFI application) with gBS->LoadImage(), passing "VenHw(...)/kernel" as device path. This causes gBS->LoadImage() to call back into our filesystem. - Appended to the downloaded command line, we pass "initrd=initrd" to the EFI stub. - Once the EFI stub is running, it loads the initial ramdisk from the "sibling" device path "VenHw(...)/initrd", also calling back into our filesystem.

We have all the required pieces in place. Let's call SetBootOrderFromQemu() in PlatformBdsPolicyBehavior(). We disable OFW-to-UEFI device path fragment translation for virtio-pci, and enable it only virtio-mmio at this time.

2015-01-02ArmVirtualizationPkg: PlatformIntelBdsLib: add basic policyLaszlo Ersek
In PlatformBdsPolicyBehavior() we should follow the same pattern as in OvmfPkg's: after the consoles are connected, - connect all drivers and devices, - enumerate all boot options, - enter the Intel BDS FrontPage if the user presses a key different from Enter. We set the countdown to 3 seconds, similarly to the timeout that we specify for ARM BDS.
