Subject: [PATCH] MdeModulePkg/PciBus: Fix bug that PCI BUS claims too much resource
Date: Thu, 16 Nov 2017 18:15:14 +0100
The bug was caused by 728d74973c9262b6c7b7ef4be213223d55affec3
"MdeModulePkg/PciBus: Count multiple hotplug resource paddings".
The patch firstly updated the Bridge->Alignment to the maximum
alignment of all devices under the bridge, then aligned the
Bridge->Length to Bridge->Alignment.
It caused too much resources were claimed.
The new patch firstly aligns Bridge->Length to Bridge->Alignment,
then updates the Bridge->Alignment to the maximum alignment of all
devices under the bridge.
Because the step to update the Bridge->Alignment is to make sure
the resource allocated to the bus under the Bridge meets all
devices alignment. But the Bridge->Length doesn't have to align
to the maximum alignment.

Subject: [PATCH] MdeModulePkg/Bds: Remove assertion in BmCharToUint
Date: Thu, 16 Nov 2017 18:04:42 +0100
BmCharToUint() could be called using external data and it
already contains logic to return -1 when data is invalid,
so removing unnecessary assertion to avoid system hang.

Subject: [PATCH] MdeModulePkg/Bds: Check variable name even *if* OptionNumber is NULL
Date: Thu, 16 Nov 2017 18:04:43 +0100
Current implementation skips to check whether the last four
characters are digits when the OptionNumber is NULL.
Even worse, it may incorrectly return FALSE when OptionNumber is
NULL.
The patch fixes it to always check the variable name even
OptionNumber is NULL.

Subject: [PATCH 2/3] OvmfPkg: create a separate PlatformDebugLibIoPort
instance for SEC
The next patch will want to add a global variable to
PlatformDebugLibIoPort, but this is not suitable for the SEC
phase, because SEC runs from read-only flash. The solution is
to have two library instances, one for SEC and another
for all other firmware phases. This patch adds the "plumbing"
for the SEC library instance, separating the INF files and
moving the constructor to a separate C source file.

Subject: [PATCH 3/3] OvmfPkg: save on I/O port accesses when the debug port is
not in use
When SEV is enabled, every debug message printed by OVMF to the
QEMU debug port traps from the guest to QEMU character by character
because "REP OUTSB" cannot be used by IoWriteFifo8. Furthermore,
when OVMF is built with the DEBUG_VERBOSE bit (value 0x00400000)
enabled in "gEfiMdePkgTokenSpaceGuid.PcdDebugPrintErrorLevel", then the
OvmfPkg/IoMmuDxe driver, and the OvmfPkg/Library/BaseMemEncryptSevLib
library instance that is built into it, produce a huge amount of
log messages. Therefore, in SEV guests, the boot time impact is huge
(about 45 seconds _additional_ time spent writing to the debug port).
While these messages are very useful for analyzing guest behavior,
most of the time the user won't be capturing the OVMF debug log.
In fact libvirt does not provide a method for configuring log capture;
users that wish to do this (or are instructed to do this) have to resort
to <qemu:arg>.
The debug console device provides a handy detection mechanism; when read,
it returns 0xE9 (which is very much unlike the 0xFF that is returned by
an unused port). Use it to skip the possibly expensive OUT instructions
when the debug I/O port isn't plugged anywhere.
For SEC, the debug port has to be read before each full message.
However:
- if the debug port is available, then reading one byte before writing
a full message isn't tragic, especially because SEC doesn't print many
messages
- if the debug port is not available, then reading one byte instead of
writing a full message is still a win.
