2014-03-31OvmfPkg: PlatformPei: lifecycle fixes for the LockBox areaLaszlo Ersek
If (mBootMode == BOOT_ON_S3_RESUME) -- that is, we are resuming --, then the patch has no observable effect. If (mBootMode != BOOT_ON_S3_RESUME && mS3Supported) -- that is, we are booting or rebooting, and S3 is supported), then the patch has no observable effect either. If (mBootMode != BOOT_ON_S3_RESUME && !mS3Supported) -- that is, we are booting or rebooting, and S3 is unsupported), then the patch effects the following two fixes: - The LockBox storage is reserved from DXE (but not the OS). Drivers in DXE may save data in the LockBox regardless of S3 support, potentially corrupting any overlapping allocations. Make sure there's no overlap. - The LockBox storage is cleared. A LockBox inherited across a non-resume reboot, populated with well-known GUIDs, breaks drivers that want to save entries with those GUIDs.

If Start() succeeds, the callback is only executed when the setup is complete (on the stack of RestoreTPL()), rather than on the stack of InstallMultipleProtocolInterfaces(), when the driver setup may yet be theoretically incomplete. If Start() fails, the protocol interface will have been uninstalled (rolled back) by the time the callback runs (again, on the stack of RestoreTPL()). Since protocol notification callbacks begin with locating the protocol interface in question, such attempts to locate will fail immediately and save some work in the callback.

2014-03-22OvmfPkg: PlatformDxe: add form widgets for video modesLaszlo Ersek
In this patch we populate the form with the two widgets related to video resolution: - A read-only string field displaying the preference for the next boot. - A drop-down list offering choices for changing the setting. This list is implemented with dynamically generated IFR opcodes. (In general, the current preference may be missing, or it may be invalid for the available video RAM size. The list of possible new settings is filtered with the video RAM size.) Because the form now becomes able to receive input, we must also implement ExtractConfig(). This function tells the HII engine about the state of the widgets. For now we set up both widgets with static data only: - The current preference always says "Unset". The driver code is still isolated from the backend (the UEFI variable store). - The list of possible resolutions offers 800x600 only. We don't interrogate the GOP yet.

We choose the Buffer Storage kind (see 29.2.5.6 "Storage" in UEFI 2.4A), because it's easy to work with. Note that the structure added in this patch has nothing to do with UEFI non-volatile variables.

2014-03-22OvmfPkg: PlatformDxe: set preferred video resolution from platform configLaszlo Ersek
The GraphicsConsoleDxe driver (in MdeModulePkg/Universal/Console) determines the preferred video resolution from the dynamic PCDs - gEfiMdeModulePkgTokenSpaceGuid.PcdVideoHorizontalResolution - gEfiMdeModulePkgTokenSpaceGuid.PcdVideoVerticalResolution Setting the graphics resolution during boot is useful when the guest OS (for lack of a dedicated display driver) continues to work with the original GOP resolution and framebuffer.

2014-03-22OvmfPkg: PlatformDxe: utility functions for saving / loading configurationLaszlo Ersek
The two functions introduced here allow the saving and loading of platform configuration to/from the non-volatile variable store. The PLATFORM_CONFIG structure and the two functions that take it / return it are generally meant for any DXE or UEFI driver that needs to access platform configuration. For now we keep this small "library" internal to PlatformDxe. The PLATFORM_CONFIG wire format is intended only to grow over time (as long as the variable GUID remains unchanged). At the introduction of new fields, new feature flags must be added, and recognized in PlatformConfigLoad().

2014-03-22OvmfPkg: introduce empty PlatformDxeLaszlo Ersek
This DXE driver will load/save persistent values for OVMF's config knobs, plus expose those knobs via HII.

2014-03-22OvmfPkg: introduce gOvmfPlatformConfigGuidLaszlo Ersek
This GUID should become a new "namespace" for UEFI variables that are specific to OVMF configuration (as opposed to standard UEFI global variables). We'll also use it as the GUID of the related HII form-set (ie. the interactive user interface).
