ArmVirtualizationQemu: ask the hardware for the timer frequency
Roughly, there are two ways to "measure ticks" in UEFI:
- the SetTimer() boot service, which sets up a one-shot or periodic event
callback, and takes the interval length in units of 100ns,
- the Stall() boot service, which stalls the caller (but does not yield
the CPU) for the interval specified. The interval is taken as a number
of microseconds.
If the platform in question also follows the PI (Platform Init)
specification, then it is recommended to implement the above UEFI services
on top of the following DXE Architectural Protocols (described in PI
Volume 2):
- Timer Architectural Protocol:
"Used to set up a periodic timer interrupt using a platform specific
timer, and a processor-specific interrupt vector. This protocol enables
the use of the SetTimer() Boot Service. [...]"
- Metronome Architectural Protocol:
"Used to wait for ticks from a known time source in a platform. This
protocol may be used to implement a simple version of the Stall() Boot
Service. [...]"
Edk2 in general, and ArmVirtualizationQemu in particular, follow the above
pattern.
SetTimer() works correctly. The underlying Timer Architectural Protocol is
provided by "ArmPkg/Drivers/TimerDxe", and that driver calls the internal
function ArmGenericTimerGetTimerFreq() to retrieve the timer frequency.
Ultimately it boils down to reading the CNTFRQ_EL0 register.
The correct behavior of SetTimer() can be observed for example:
- in the grub-efi countdown ("grub-core/kern/arm/efi/init.c"),
- in the Intel BDS front page countdown
("IntelFrameworkModulePkg/Universal/BdsDxe/FrontPage.c").
However, Stall() doesn't work correctly. The underlying Metronome
Architectural Protocol is provided by "EmbeddedPkg/MetronomeDxe", which
further delegates the job to the TimerLib library class. That in turn is
resolved to the "ArmPkg/Library/ArmArchTimerLib" instance, which
(finally!) takes the timer frequency from "PcdArmArchTimerFreqInHz".
In ArmVirtualizationQemu we currently specify 100MHz for this PCD. Alas,
that's incorect for:
- both QEMU/TCG (which emulates 62.5MHz, see GTIMER_SCALE in
"target-arm/internals.h"),
- and KVM (where the host's virtualized timer can tick at 50 MHz, for
example).
Set the PCD to 0, asking ArmArchTimerLib to interrogate CNTFRQ_EL0 as
well.
The change can be tested with eg. the following callers of Stall():
- the UEFI Shell's countdown -- before it runs "startup.nsh" -- relies on
Stall(),
- the UEFI shell command "stall" also uses Stall(). (Time it with a
stopwatch.)

ArmVirtPkg: add QemuFwCfgToPcdDxe
Many universal DXE drivers in edk2 can be controlled by setting dynamic
PCDs. Such a PCD must be set before the consumer DXE driver is dispatched.
(In general we assume that the DXE driver will consume the PCD in its
entry point, or in the constructor of a library instance it links against.
In special cases this requirement can be relaxed a bit, if we know that
the DXE driver accesses the PCD only in a protocol member function that it
exports.)
On the QEMU platform, the PCD values to be set for the universal drivers
are frequently derived from fw_cfg files that QEMU exports.
In OvmfPkg we tend to handle this in the following way:
- For IA32 and X64, OvmfPkg provides a QemuFwCfgLib instance that is
usable in PEI.
- In PlatformPei, fw_cfg files can be loaded and transformed to PCD
values.
- Any DXE driver is bound to be dispatched after the PEI phase is done.
(In specific cases other ordering solutions might be possible, via Depex
or protocol notify, etc.)
In ArmVirtPkg/ArmVirtQemu, things differ a bit:
- We don't have an ArmVirtPkg-specific ("Platform") PEIM. This is actually
a good thing for now, so let's not introduce one just for this purpose.
- Even if we had such a PEIM, it could not easily access fw_cfg: the MMIO
addresses of the fw_cfg device are available only in the DTB that QEMU
exports.
(Accordingly, our QemuFwCfgLib instance is restricted to DXE_DRIVER
modules: VirtFdtDxe parses the DTB, stores the fw_cfg addresses in PCDs,
and then QemuFwCfgLib's constructor fetches those PCDs.)
There are some examples in ArmVirtPkg where early code is forced to
parse the DTB manually, but those examples are all painful, and our goal
here (controlling universal DXE drivers) doesn't justify more of that
pain.
Therefore, introduce a separate, minimal DXE driver that is dispatched
strictly after VirtFdtDxe (so that it can use QemuFwCfgLib), and strictly
before other DXE drivers (so that it can set dynamic PCDs for them).
Because VirtFdtDxe is already ordered with the APRIORI DXE file, it is
simplest to do the same for the new driver.
Actual fw_cfg files and PCDs shall be accessed in future patches.
