- Registering a interrupt handler implicitly enables said interrupt. This
is in the UEFI Spec. No need to enable the interrupts a second time.
- Make sure the Timer is completely disabled before configuring it. Only
enable after configuration is complete.

The aim of the condition is to check if we should use the default BaudRate
value (case when *BaudRate == 0).

r14252 causes OVMF to crash if SECURE_BOOT_ENABLE is set,
because PcdMaxVariableSize is set to a larger value than
required. In other platforms, 0x2000 seems to be sufficient.

OvmfPkg's file-based NvVar storage is read back as follows at boot (all
paths under OvmfPkg/Library/):
PlatformBdsPolicyBehavior() [PlatformBdsLib/BdsPlatform.c]
PlatformBdsRestoreNvVarsFromHardDisk()
VisitAllInstancesOfProtocol
for each simple file system:
VisitingFileSystemInstance()
ConnectNvVarsToFileSystem() [NvVarsFileLib/NvVarsFileLib.c]
LoadNvVarsFromFs() [NvVarsFileLib/FsAccess.c]
ReadNvVarsFile()
+-------------> SerializeVariablesSetSerializedVariables() [SerializeVariablesLib/SerializeVariablesLib.c]
| SerializeVariablesIterateInstanceVariables()
| +-------------> IterateVariablesInBuffer()
| | for each loaded / deserialized variable:
| +-|-----------------> IterateVariablesCallbackSetSystemVariable()
| | | gRT->SetVariable()
| | |
| | IterateVariablesInBuffer() stops processing variables as soon as the
| | first error is encountered from the callback function.
| |
| | In this case the callback function is
| IterateVariablesCallbackSetSystemVariable(), selected by
SerializeVariablesSetSerializedVariables().
The result is that no NvVar is restored from the file after the first
gRT->SetVariable() failure.
On my system such a failure
- never happens in an OVMF build with secure boot disabled,
- happens *immediately* with SECURE_BOOT_ENABLE, because the first
variable to restore is "AuthVarKeyDatabase".
"AuthVarKeyDatabase" has the EFI_VARIABLE_AUTHENTICATED_WRITE_ACCESS
attribute set. Since the loop tries to restore it before any keys (PK, KEK
etc) are enrolled, gRT->SetVariable() rejects it with
EFI_SECURITY_VIOLATION. Consequently the NvVar restore loop terminates
immediately, and we never reach non-authenticated variables such as
Boot#### and BootOrder.
Until work on KVM-compatible flash emulation converges between qemu and
OvmfPkg, improve the SECURE_BOOT_ENABLE boot experience by masking
EFI_SECURITY_VIOLATION in the callback:
- authenticated variables continue to be rejected same as before, but
- at least we allow the loop to progress and restore non-authenticated
variables, for example boot options.
