66127011a5 ArmPkg/ArmGicDxe ARM: fix encoding for GICv3 interrupt acknowledge
Fix a typo in the 32-bit ARM version of the GICv3 driver, which uses
the wrong system register encoding to access ICC_IAR1, and attempted
to access ICC_IAR0 instead. This results in boot time hangs both
under QEMU emulation and on real hardware.

9cabe9d457 MdePkg/BaseIoLibIntrinsicArmVirt ARM: avoid double word loads and stores
BaseIoLibIntrinsicArmVirt was created to prevent LTO from merging
accesses to MMIO regions, resulting in instructions with multiple
output registers that KVM on ARM cannot emulate (since the exception
syndrome information that KVM relies on can only describe a single
output register)

However, using double word loads on ARM amounts to the same thing,
and so code that relies on doing 64-bit MMIO to regions that are
emulated under KVM (such as the GICv3 TYPER register) will still
suffer from the original issue.

So replace ldrd and strd with equivalent two instruction sequences.

8558838922 UefiCpuPkg/CommonFeature: Always set FEATURE_CONTROL.Lock
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1305

The patch reverts commit 1ed6498c4a0210204bf4b95cc0c0cd6623ad6a0b
* UefiCpuPkg/CommonFeature: Skip locking when the feature is disabled

FEATURE_CONTROL.Lock bit is controlled by feature
CPU_FEATURE_LOCK_FEATURE_CONTROL_REGISTER. The commit 1ed649 fixes
a bug that when the feature is disabled, the Lock bit is cleared.
But it's a security hole if the bit is cleared when booting OS.
We can argue that platform needs to make sure the value
of PcdCpuFeaturesUserConfiguration should be set properly to make
sure feature CPU_FEATURE_LOCK_FEATURE_CONTROL_REGISTER is enabled.

But it's better to guarantee this in the generic core code.

bd224a5dad MdeModulePkg/NvmExpressPei: Refine data buffer & len check in PassThru
REF:https://bugzilla.tianocore.org/show_bug.cgi?id=1142

The fix is similar to commit ebb6c7633bca47fcd5b460a67e18e4a717ea91cc.
We found that a similar fix should be applied to the NVMe PEI driver as
well. Hence, this one is for the PEI counterpart driver.

According to the the NVM Express spec Revision 1.1, for some commands
(like Get/Set Feature Command, Figure 89 & 90 of the spec), the Memory
Buffer maybe optional although the command opcode indicates there is a
data transfer between host & controller (Get/Set Feature Command, Figure
38 of the spec).

Hence, this commit refine the checks for the 'TransferLength' and
'TransferBuffer' field of the
EDKII_PEI_NVM_EXPRESS_PASS_THRU_COMMAND_PACKET structure to address this
issue.

9bae7811d9 UefiCpuPkg/PiSmmCpuDxeSmm: Separate semaphore container.
In current implementation, core and package level sync uses same semaphores.
Sharing the semaphore may cause wrong execution order.
For example:
1. Feature A has CPU_FEATURE_CORE_BEFORE dependency with Feature B.
2. Feature C has CPU_FEATURE_PACKAGE_AFTER dependency with Feature B.
The expected feature initialization order is A B C:
A ---- (Core Depends) ----> B ---- (Package Depends) ----> C

For a CPU has 1 package, 2 cores and 4 threads. The feature initialization
order may like below:

   Thread#1             Thread#2       Thread#3         Thread#4
   [A.Init]             [A.Init]                        [A.Init]
Release(S1, S2)        Release(S1, S2)                Release(S3, S4)
Wait(S1) * 2           Wait(S2) * 2  <------------------------------- Core sync

   [B.Init]             [B.Init]
Release (S1,S2,S3,S4)
Wait (S1) * 4  <----------------------------------------------------- Package sync
                                                      Wait(S4 * 2) <- Core sync
                                                        [B.Init]

In above case, for thread#4, when it syncs in core level, Wait(S4) * 2 isn't
blocked and [B.Init] runs. But [A.Init] hasn't run in thread#3. It's wrong!
Thread#4 should execute [B.Init] after thread#3 executes [A.Init] because B
core level depends on A.

The reason of the wrong execution order is that S4 is released in thread#1
by calling Release (S1, S2, S3, S4) and in thread #4 by calling
Release (S3, S4).

To fix this issue, core level sync and package level sync should use separate
semaphores.

In above example, the S4 released in Release (S1, S2, S3, S4) should not be the
same semaphore as that in Release (S3, S4).

Wait (S1) * 4  <----------------------------------------------------- Package sync
                                                      Wait(S4 * 2) <- Core sync
                                                        [B.Init]

In above case, for thread#4, when it syncs in core level, Wait(S4) * 2 isn't
blocked and [B.Init] runs. But [A.Init] hasn't run in thread#3. It's wrong!
Thread#4 should execute [B.Init] after thread#3 executes [A.Init] because B
core level depends on A.

The reason of the wrong execution order is that S4 is released in thread#1
by calling Release (S1, S2, S3, S4) and in thread #4 by calling
Release (S3, S4).

To fix this issue, core level sync and package level sync should use separate
semaphores.

In above example, the S4 released in Release (S1, S2, S3, S4) should not be the
same semaphore as that in Release (S3, S4).

c1528b855c UefiCpuPkg/RegisterCpuFeaturesLib: Adjust Order.
V2 changes:
V1 change has regression which caused by change feature order.
V2 changes logic to detect dependence not only for the
neighborhood features. It need to check all features in the list.

V1 Changes:
In current code logic, only adjust feature position if current
CPU feature position not follow the request order. Just like
Feature A need to be executed before feature B, but current
feature A registers after feature B. So code will adjust the
position for feature A, move it to just before feature B. If
the position already met the requirement, code will not adjust
the position.

This logic has issue when met all below cases:
1. feature A has core or package level dependence with feature B.
2. feature A is register before feature B.
3. Also exist other features exist between feature A and B.

Root cause is driver ignores the dependence for this case, so
threads may execute not follow the dependence order.

Fix this issue by change code logic to adjust feature position
for CPU features which has dependence relationship.

In function UiDisplayMenu, the NewPos ptr which used to point to the
highlight menu entry. It will always point to the menu entry which
need to be highlighted or the gMenuOption menu if the highlight menu
is not found.
So we can remove the NULL ptr check for NewPos in this function.
And add the ASSERT code to avoid if any false positive reports
of NULL pointer dereference issue raised from static analysis.

e6459b9e6c MdePkg/BaseSynchronizationLib: Fix InternalSync[De|In]crement
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1303

Today's code generates assembly code as below for
InternalSyncIncrement:
  __asm__ __volatile__ (
    "movl    $1, %%eax  \n\t"
    "lock               \n\t"
    "xadd    %%eax, %1  \n\t"
    "inc     %%eax      \n\t"
    : "=a" (Result),          // %0
      "+m" (*Value)           // %1
    :                         // no inputs that aren't also outputs
    : "memory",
      "cc"
    );

 0:       55      pushl   %ebp
 1:       89 e5   movl    %esp, %ebp
 3:       8b 45 08        movl    8(%ebp), %eax
 6:       b8 01 00 00 00  movl    $1, %eax
 b:       f0      lock
 c:       0f c1 00        xaddl   %eax, _InternalSyncIncrement(%eax)
 f:       40      incl    %eax
10:       5d      popl    %ebp
11:       c3      retl

Line #3 and Line #6 both use EAX as destination register.
Line #c uses EAX and (EAX).

The output operand "=a" tells GCC that EAX is used for output.
But GCC only assumes that EAX will be used in the very last
instruction.

Per GCC document,
"Use the '&' constraint modifier on all output operands that must
 not  overlap an input. Otherwise, GCC may allocate the output
 operand in the same register as an unrelated input operand, on
 the assumption that the assembler code consumes its inputs before
 producing outputs. This assumption may be false if the assembler
 code actually consists of more than one instruction."

"=&a" should be used to tell GCC not use EAX before the assembly.

c60d36b4d1 UefiCpuPkg/SmmCpu: Block access-out only when static paging is used
When static paging is disabled, page table for below 4GB is created
and page table for above 4GB is created dynamically in page fault
handler.

Today's implementation only allow SMM access-out to below types of
memory address no matter static paging is enabled or not:
1. Reserved, run time and ACPI NVS type
2. MMIO

But certain platform feature like RAS may need to access other types
of memory from SMM. Today's code blocks these platforms.
This patch simplifies the policy to only block when static paging
is used so that the static paging can be disabled in these platforms
to meet their SMM access-out need.

Setting PcdCpuSmmStaticPageTable to FALSE can disable the static
paging.

Setting GICD_IROUTERn.IRM and GICD_IROUTERn.{Aff3,Aff2,Aff1,Aff0}
at the same time is nonsensical (see 8.9.13 in the GICv3 spec, which
says of GICD_IROUTERn.IRM that "When this bit is set to 1,
GICD_IROUTER<n>.{Aff3,Aff2,Aff1,Aff0} are UNKNOWN"). There is also no
guarantee that IRM is implemented (see GICD_TYPER.No1N which indicates
whether the implementation supports this or not).

Let's thus not set this bit, as we want all SPIs to be delivered to the
same CPU, and not be broadcast to all of them.

0adc6eae94 MdeModulePkg/Core: fix ineffective guard page issue
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1295

This issue originates from following patch which allows to enable
paging if PcdImageProtectionPolicy and PcdDxeNxMemoryProtectionPolicy
(in addition to PcdSetNxForStack) are set to enable related features.

  5267926134d17e86672b84fd57b438f05ffa68e1

Due to above change, PcdImageProtectionPolicy will be set to 0 by
default in many platforms, which, in turn, cause following code in
MdeModulePkg\Core\Dxe\Misc\MemoryProtection.c fail the creation of
notify event of CpuArchProtocol.

1138:  if (mImageProtectionPolicy != 0 ||
           PcdGet64 (PcdDxeNxMemoryProtectionPolicy) != 0) {
1139:  Status = CoreCreateEvent (
...
1142:             MemoryProtectionCpuArchProtocolNotify,
...
1145:             );

Then following call flow won't be done and Guard pages will not be
set as not-present in SetAllGuardPages() eventually.

   MemoryProtectionCpuArchProtocolNotify()
=> HeapGuardCpuArchProtocolNotify()
=> SetAllGuardPages()

The solution is removing the if(...) statement so that the notify
event will always be created and registered. This won't cause
unnecessary code execution because, in the notify event handler,
the related PCDs like

    PcdImageProtectionPolicy and
    PcdDxeNxMemoryProtectionPolicy

will be checked again before doing related jobs.

8a7ff892ca MdeModulePkg/Core: fill logic hole in MemoryProtectionCpuArchProtocolNotify
At the end of of MemoryProtectionCpuArchProtocolNotify there's cleanup
code to free resource. But at line 978, 994, 1005 the function returns
directly. This patch use "goto" to replace "return" to make sure the
resource is freed before exit.

1029:  CoreCloseEvent (Event);
1030:  return;

There's another memory leak after calling gBS->LocateHandleBuffer() in
the same function:

  Status = gBS->LocateHandleBuffer (
                  ByProtocol,
                  &gEfiLoadedImageProtocolGuid,
                  NULL,
                  &NoHandles,
                  &HandleBuffer
                  );

HandleBuffer is allocated in above call but never freed. This patch
will also add code to free it.

This reverts commit c137d95081690d4877fbeb5f1856972e84ac32f2.

The VMWare SVGA model now -- since commit 104bd1dc70 in QEMU --
falls back to stdvga (that is, Bochs) if we don't setup VMWare SVGA
FIFO.

To simplify QemuVideoDxe, we don't intend to implement the VMWare SVGA
FIFO setup feature. It means our current VMW SVGA driver code is
basically dead. To simplify the problem, we will replace the old
VMWare SVGA driver to Bochs interface. It should work on all QEMU
version.

The first step for using Bochs interface is to revert old driver.
