2016-10-16OvmfPkg/QemuVideoDxe: upgrade VERBOSE debug messages to INFOLaszlo Ersek
In commit 5b2291f9567a ("OvmfPkg: QemuVideoDxe uses MdeModulePkg/FrameBufferLib"), QemuVideoDxe was rebased to FrameBufferBltLib. The FrameBufferBltLib instance added in commit b1ca386074bd ("MdeModulePkg: Add FrameBufferBltLib library instance") logs many messages on the VERBOSE level; for example, a normal boot with OVMF can produce 500+ "VideoFill" messages, dependent on the progress bar, when the VERBOSE bit is set in PcdDebugPrintErrorLevel. While FrameBufferBltLib is certainly allowed to log such messages on the VERBOSE level, we should separate those frequent messages from the (infrequent) ones produced by QemuVideoDxe itself. QemuVideoDxe logs VERBOSE messages in three locations (in two functions) at the moment. All of them are infrequent: both QemuVideoBochsModeSetup() and InstallVbeShim() are called from QemuVideoControllerDriverStart(), that is, when a device is bound. Upgrade these messages to INFO level, so that VERBOSE can be disabled in PcdDebugPrintErrorLevel -- perhaps selectively for OvmfPkg/QemuVideoDxe -- without hiding these infrequent messages.

2016-09-01OvmfPkg/QemuVideoDxe: don't incorrectly bind virtio-gpu-pciLaszlo Ersek
The PCI (Vendor ID, Device ID) pair (0x1af4, 0x1050) stands for both the virtio-vga and the virtio-gpu-pci device models of QEMU. They differ in two things: - the former has a VGA-compatibility linear framebuffer on top of the latter, - the former has PCI_CLASS_DISPLAY_VGA device class, while the latter has PCI_CLASS_DISPLAY_OTHER. In commit 94210dc95e9f ("OvmfPkg: QemuVideoDxe: add virtio-vga support"), we enabled QemuVideoDxe to drive virtio-vga simply by adding its (Vendor ID, Device ID) pair to gQemuVideoCardList. This change inadvertently allowed QemuVideoDxe to bind virtio-gpu-pci, which it cannot drive though. Restrict QemuVideoDxe to PCI_CLASS_DISPLAY_VGA, in order to exclude virtio-gpu-pci. For the other cards that QemuVideoDxe drives, this makes no difference. (Note that OvmfPkg's PlatformBootManagerLib instance has always only added PCI_CLASS_DISPLAY_VGA devices to ConOut; see DetectAndPreparePlatformPciDevicePath().)

The SegmentC local variable has type EFI_PHYSICAL_ADDRESS for (justified) style reasons. However, the 64-bit bit-shifts that it undergoes result in intrinsic calls when built with VS2010 for Ia32 / NOOPT. The concrete value of SegmentC, 0xC0000, and the results of the bitops that are based on it, are statically computeable. Cast SegmentC to UINT32 before subjecting it to bitwise operations; we can see in advance that this won't lead to range loss.

2014-08-29OvmfPkg: QemuVideoDxe: work around misreported QXL framebuffer sizeLaszlo Ersek
When setting up the list of GOP modes offered on QEMU's stdvga ("VGA") and QXL ("qxl-vga") video devices, QemuVideoBochsModeSetup() filters those modes against the available framebuffer size. (Refer to SVN r15288 / git commit ec88061e.) The VBE_DISPI_INDEX_VIDEO_MEMORY_64K register of both stdvga and QXL is supposed to report the size of the drawable, VGA-compatibility framebuffer. Instead, up to and including qemu-2.1, this register actually reports the full video RAM (PCI BAR 0) size. In case of stdvga, this happens to be correct, because on that card the full PCI BAR 0 is usable for drawing; there is no difference between "drawable framebuffer size" and "video RAM (PCI BAR 0) size". However, on the QXL card, only an initial portion of the video RAM is suitable for drawing, as compatibility framebuffer; and the value currently reported by VBE_DISPI_INDEX_VIDEO_MEMORY_64K overshoots the valid size. Beyond the drawable range, the video RAM contains buffers and structures for the QXL guest-host protocol. Luckily, the size of the drawable QXL framebuffer can also be read from a register in the QXL ROM BAR (PCI BAR 2), so let's retrieve it from there. Without this fix, OVMF offers too large resolutions on the QXL card (up to the full size of the video RAM). If a GOP client selects such a resolution and draws into the video RAM past the compatibility segment, then the guest corrupts its communication structures (which is invalid guest behavior).

2014-05-20OvmfPkg: QemuVideoDxe: Int10h stub for Windows 7 & 2008 (stdvga, QXL)Laszlo Ersek
The Windows 2008 R2 SP1 (and Windows 7) UEFI guest's default video driver dereferences the real mode Int10h vector, loads the pointed-to handler code, and executes what it thinks to be VGA BIOS services in an internal real-mode emulator. Consequently, video mode switching doesn't work in Windows 2008 R2 SP1 when it runs on the pure UEFI build of OVMF, making the guest uninstallable. This patch adds a VGABIOS "shim" to QemuVideoDxe. For the first stdvga or QXL card bound, an extremely stripped down VGABIOS imitation is installed in the C segment. It provides a real implementation for the few services that are in fact necessary for the win2k8r2sp1 UEFI guest, plus some fakes that the guest invokes but whose effect is not important. The C segment is not present in the UEFI memory map prepared by OVMF. We never add memory space that would cover it (either in PEI, in the form of memory resource descriptor HOBs, or in DXE, via gDS->AddMemorySpace()). This way the handler body is invisible to all non-buggy UEFI guests, and the rest of edk2. The Int10h real-mode IVT entry is covered with a Boot Services Code page, making that too unaccessible to the rest of edk2. (Thus UEFI guest OSes different from the Windows 2008 family can reclaim the page. The Windows 2008 family accesses the page at zero regardless of the allocation type.) The patch is the result of collaboration: Initial proof of concept IVT entry installation and handler skeleton (in NASM) by Jordan Justen. Service tracing and implementation, data collection/analysis, and C coding by yours truly. Last minute changes by Gerd Hoffmann: - Use OEM mode number (0xf1) instead of standard 800x600 mode (0x143). The resolution of the OEM mode (0xf1) is not standardized; the guest can't expect anything from it in advance. - Use 1024x768 rather than 800x600 for more convenience in the Windows 2008 R2 SP1 guest during OS installation, and after normal boot until the QXL XDDM guest driver is installed.

2014-03-22OvmfPkg: QemuVideoDxe: serialize Start() against callbacksLaszlo Ersek
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.

2014-03-03OvmfPkg: QemuVideoDxe: filter BOCHS modes vs. available frame buffer sizeLaszlo Ersek
In the next patch we'll add many new BOCHS modes, some of which require large frame buffers. The size of the QXL VGA compatibility framebuffer can be changed with the -global qxl-vga.vgamem_mb=$NUM_MB QEMU option. If $NUM_MB would exceed 32, then the following two QEMU options are necessary instead: -global qxl-vga.vgamem_mb=$NUM_MB \ -global qxl-vga.ram_size_mb=$((NUM_MB*2)) because the compatibility framebuffer can't cover more than half of PCI BAR #0. The latter defaults to 64MB in size, and is controlled by "ram_size_mb".

After checking all references, rename the field to "InternalModeIndex". Also, when filling in the card type independent QEMU_VIDEO_MODE_DATA array from the card type specific mode array, distinguish the GOP mode number from the internal mode index in the debug message.

HardwareNeedsStarting = FALSE InstallMultipleProtocolInterfaces(... GOP ...) That is, when QemuVideoGraphicsOutputQueryMode() is reached, HardwareNeedsStarting is always FALSE.
