  - Support Platform Initialization(PI) specification 1.3.
  - Support execution as a coreboot payload.
  - Support USB 3.0

The following features are not supported currently and have not been validated:
  - GCC Tool Chains
  - SMM Execution Environment

OvmfPkg: XenConsoleSerialPortLib: deal with output overflow

It is the responsibility of the SerialPortLib implementation
to deal with flow control if the underlying medium cannot keep
up with the inflow of data.

So in our SerialPortWrite () function, we should spin as long
as we need to in order to deliver all the data instead of giving
up and returning a smaller value than the number of bytes we were
given. Also, remove the 'if (Sent > 0)' condition on the signalling
of the event channel: if the buffer is full and we haven't been able
to add any more data, it makes perfect sense to signal the event
channel again, even if we have done so before when we did write
the data.

Also, this patch brings the implementation of XenSerialPortLib
in sync with the library class documentation.

Gabriel Somlo [Thu, 26 Mar 2015 19:06:07 +0000 (19:06 +0000)]
OvmfPkg: Q35: Use correct ACPI PM control register:bit

On PIIX4, function 3, the PMREGMISC register at offset 0x80, with
default value 0x00 has its bit 0 (PMIOSE) indicate whether the PM
IO space given in the PMBA register (offset 0x40) is enabled.
PMBA must be configured *before* setting this bit.

On Q35/ICH9+, function 0x1f, the equivalent role is fulfilled by
bit 7 (ACPI_EN) in the ACPI Control Register (ACPI_CNTL) at offset
0x44, also with a default value of 0x00.

Currently, OVMF hangs when Q35 reboots, because while PMBA is reset
by QEMU, the register at offset 0x80 (matching PMREGMISC on PIIX4)
is not reset, since it has a completely different meaning on LPC.
As such, the power management initialization logic in OVMF finds
the "PMIOSE" bit enabled after a reboot and decides to skip setting
PMBA. This causes the ACPI timer tick routine to read a constant
value from the wrong register, which in turn causes the ACPI delay
loop to hang indefinitely.

This patch modifies the Base[Rom]AcpiTimerLib constructors and the
PlatformPei ACPI PM init routines to use ACPI_CNTL:ACPI_EN instead
of PMREGMISC:PMIOSE when running on Q35.

QEMU commit aa685789 ("xhci: generate a Transfer Event for each Transfer
TRB with the IOC bit set") fixed an emulation problem in QEMU; we can now

XHCI emulation is reportedly more virtualization-friendly than EHCI,
consuming less CPU.

The driver can be tested with the following QEMU command line options:

  -device nec-usb-xhci -device usb-kbd

This patch should not regress existing QEMU command lines (ie. trigger an
ASSERT() in XhciDxe that fails on pre-aa685789 QEMU) because QEMU's
"-device nec-usb-xhci" has never before resulted in USB devices that
worked with edk2 firmware builds, hence users have never had a reason to
add that option.

6 years agoArmVirtualizationPkg/ArmVirtualizationQemu: include XHCI driver
Laszlo Ersek [Mon, 16 Mar 2015 19:57:06 +0000 (19:57 +0000)]
ArmVirtualizationPkg/ArmVirtualizationQemu: include XHCI driver

The "virt" machine type of qemu-system-(arm|aarch64) had no PCIe support
prior to qemu commit

  4ab29b82 arm: Add PCIe host bridge in virt machine

With that commit, the "virt" board acquired the capability to expose an
XHCI controller. Using a USB keyboard as example, the command line options
were

  -device nec-usb-xhci -device usb-kbd

However, due to a slight XHCI emulation bug in QEMU --  dating back to
several years earlier -- edk2's XHCI driver would encounter a failed
ASSERT().

This emulation problem has been fixed in QEMU commit

  aa685789 xhci: generate a Transfer Event for each Transfer TRB with the
           IOC bit set

and now edk2's XHCI driver works well on QEMU's "nec-usb-xhci" device.
Let's enable the driver in ArmVirtualizationQemu, as XHCI emulation is
reportedly more virtualization-friendly than EHCI, consuming less CPU.

(ArmVirtualizationXen is not modified because it includes no USB-related
drivers at all.)

This patch should not regress existing QEMU command lines (ie. expose the
failed ASSERT()) because QEMU's "-device nec-usb-xhci" has never before
resulted in USB devices that worked with edk2 firmware builds, hence users
have never had a reason to add that option.

Now that they learn about XHCI support in ArmVirtualizationQemu by reading
this commit message, they (or their packagers) will also know to update
qemu to aa685789 or later (in practice that means the upcoming 2.3
release), at least if they want to use '-device nec-usb-xhci' with edk2,

ArmVirtualizationPkg: build UEFI shell from source

Including a prebuilt shell executable in the firmware binary is suboptimal
practice, especially given that the source code of the UEFI shell resides
in the same edk2 tree. Benefits of building the shell from source are
partly technical (a developer patching the shell can actually see the

OvmfPkg: replace strict XenHypercallLib construction with explicit query

XenConsoleSerialPortLib. Currently, when XenBusDxe starts on a non-Xen X86
platform (ie. as part of OVMF not running on Xen), the X86XenHypercallLib
instance built into it fails to initialize, which triggers an ASSERT() in
auto-generated code.

Instead, let's call XenHypercallIsAvailable() in the driver's entry point,
and exit cleanly when the driver is started on a non-Xen platform.

Modify the constructor of XenConsoleSerialPortLib similarly; we shouldn't
proceed if Xen is not available. In practice this check should never fail,
because XenConsoleSerialPortLib is only used on ARM, and
ArmXenHypercallLib is always available; but nonetheless we should be
pedantic.
