Hao Wu 23a596db1b MdeModulePkg Ata: Use the new (incompatible) PortMultiplierPort semantics
The Mantis ticket 1353 <https://mantis.uefi.org/mantis/view.php?id=1353>
and Mantis ticket 1472 <https://mantis.uefi.org/mantis/view.php?id=1472>
updated the description of the port multiplier port number parameter in
SATA Device Path Node and ATA Pass-Through Protocol.

Now, this parameter should be set to 0xFFFF instead of 0 to indicate that
an ATA device is directly attached on the controller port.

Please note that this is an incompatible change. The consumer of SATA
device path or ATA_PASS_THRU needs to re-examine its usage to follow UEFI
2.5 mantis 1353 and 1472.

'PortMultiplierPort' parameter description for the following services in
EFI_ATA_PASS_THRU_PROTOCOL:

Enhance the error handling:
1. When the device is unlocked at BIOS phase and system does a warm reboot,
the device may be still in unlock status if it uses external power. For
such case, we would still popup password window to ask user input. If
user presses ESC key here, we would force the system shut down or ask
user input again to avoid security hole.
2. When user reach max retry count, force shutdown.

PL031RealTimeClockLib is a base library that could potentially (although
unlikely) be incorporated into other modules than the DXE_RUNTIME_DRIVER
module that it was intended to complement.

This means the library has no business whatsoever setting the Runtime

instance will 'win', and the pointers may end up referring to a module
that is not a DXE_RUNTIME_DRIVER). So remove the assignment altogether.

Ruiyu Ni c5be19f378 MdeModulePkg/PciHostBridgeLib: Add ResourceAssigned field
Some platform doesn't require PciBus driver to assign resource
to PCI devices which causes PciRootBridgeIo.Configuration() cannot
return correct resource information to caller.

When resource assignment by PciBus is not mandatory, only light
version of PCI bus enumeration is performed, which only collects
the device resource consumption and publishes the PciIo instance.
The corresponding logic is in PciEnumeratorLight() in PciBus driver.

But PciEnumeratorLight() still depends on
PciRootBridgeIo.Configuration() returns the starting bus number in
order to search down to find all PCI devices under the root bridge.

When ResourceAssigned in PCI_ROOT_BRIDGE returned by
PciHostBridgeGetRootBridges() is TRUE, PciHostBridge driver treats
the Bus/Io/Mem/MemAbove4G/PMem/PMemAbove4G as the resource that are
*actually assigned* to the root bridge, instead of the resource that
*can be assigned* to the root bridge.
So that PciRootBridgeIo.Configuration() can return the correct
information.

This patch adds helpers to provide these delays automatically, by

LAN9118 datasheet). This approach allows the device register file itself
to provide the required delay, avoiding issues with early write
acknowledgement, or re-ordering of MMIO accesses aganist other
instructions (e.g. the delay loop).

Mark Rutland 28f52b9fae Revert "EmbeddedPkg/Lan9118Dxe: use MemoryFence"
Commit a4626006bb ("EmbeddedPkg/Lan9118Dxe: use MemoryFence")
replaced some stalls with memory fences, on the presumption that these
were erroneously being used to order memory accesses. However, this was
not the case.

LAN9118 devices require a timing delay between state-changing
reads/writes and subsequent reads, as updates to the register file are
asynchronous and the effects of state-changes are not immediately
visible to subsequent reads.

This delay cannot be ensured through the use of memory barriers, which
only enforce observable ordering, and not timing. Thus, converting these
stalls to memory fences was erroneous, and may result in stale values
being read.

This reverts commit a4626006bb.

When we split a block entry into a table entry, the UXN/PXN/XN permission
attributes are inherited both by the new table entry and by the new block
entries at the next level down. Unlike the NS bit, which only affects the
next level of lookup, the XN table bits supersede the permissions of the
final translation, and setting the permissions at multiple levels is not
only redundant, it also prevents us from lifting XN restrictions on a
subregion of the original block entry by simply clearing the appropriate
bits at the lowest level.

So drop the code that sets the UXN/PXN/XN bits on the table entries.

In the DmaMap () operation, if the region to be mapped happens to be
aligned to the Cache Writeback Granule (CWG) (whose value is typically
64 or 128 bytes and 2 KB maximum), we remap the memory as uncached.

Since remapping memory occurs at page granularity, while the buffer and the
CWG may be much smaller, there is no telling what other memory we affect
by doing this, especially since the operation is not reverted in DmaUnmap().

So remove the remapping call.

Ard Biesheuvel a24f7d6680 ArmPkg/ArmDmaLib: reject consistent DMA mappings of cached memory
DmaMap () operations of type MapOperationBusMasterCommonBuffer should
return a mapping that is coherent between the CPU and the device. For
this reason, the API only allows DmaMap () to be called with this operation
type if the memory to be mapped was allocated by DmaAllocateBuffer (),
which in this implementation guarantees the coherency by using uncached
mappings on the CPU side.

This means that, if we encounter a cached mapping in DmaMap () with this
operation type, the code is either broken, or someone is violating the
API, but simply proceeding with a double buffer makes no sense at all,
and can only cause problems.

So instead, actively reject this operation type for cached memory mappings.

Ruiyu Ni 9c0dc0b01a MdeModulePkg/PciSioSerialDxe: Do not flush the UART
The patch aligns to the IntelFrameworkModulePkg/Bus/Isa/IsaSerialDxe
driver not flush the UART in Reset() and SetAttributes() function.
It was found the flush causes hang on certain PCI serial devices.

Hao Wu 09abc63675 MdeModulePkg RamDiskDxe: Fix wrong HII behavior for more than 8 RAM disks
The RamDiskDxe driver originally uses a variable-length HII varstore to
retrieve the HII checkbox status of each registered RAM disk.

However, HII does not support the variable-length varstore feature.
Therefore, only the checkbox status for the first 8 RAM disks are tracked
for the following definition of HII varstore structure considering the
alignment:

typedef struct {
  UINT64    Size;
  UINT8     RamDiskList[0];
  } RAM_DISK_CONFIGURATION;

This commit uses the private data of each registered RAM disks to track
the HII checkbox status instead to resolve the issue.

Hao Wu 259d87146b OvmfPkg: Modify FDF/DSC files for RamDiskDxe's adding NFIT report feature
The RamDiskDxe driver in MdeModulePkg now will use EFI_ACPI_TABLE_PROTOCOL
and EFI_ACPI_SDT_PROTOCOL during reporting RAM disks to NVDIMM Firmware
Interface Table (NFIT).

A Pcd 'PcdInstallAcpiSdtProtocol' controls whether the
EFI_ACPI_SDT_PROTOCOL will be produced. Its default value is set to FALSE
in MdeModulePkg. To make the NFIT reporting feature working properly under
OVMF, the patch will set the Pcd to TRUE in OVMF DSC files.

Also, the RamDiskDxe driver will sometimes report a NVDIMM Root Device
using ASL code which is put in a Secondary System Description Table (SSDT)
according to the ACPI 6.1 spec.

Locating the SSDT requires modifying the [Rule.Common.DXE_DRIVER] field in
OVMF FDF files.

Hao Wu 07a3fecd4c MdeModulePkg RamDiskDxe: Report ACPI NFIT for reserved memory RAM disks
The RamDiskDxe now will report RAM disks with reserved memory type to NFIT
in the ACPI table.

This commit will also make sure that an NVDIMM root device exists in the
\SB scope before reporting any RAM disk to NFIT.

To properly report the NVDIMM root device, one will need to append the
following content in the [Rule.Common.DXE_DRIVER] field in platform FDF
files:

RAW ACPI  Optional                |.acpi
RAW ASL   Optional                |.aml

Ard Biesheuvel cd82e330bb ArmPkg/DefaultExceptionHandlerLib: add stack dump to exception handling code
This adds a partial stack dump (256 bytes at either side of the stack
pointer) to the CPU state dumping routine that is invoked when taking an
unexpected exception. Since dereferencing the stack pointer may itself
fault, ensure that we don't enter the dumping routine recursively.

Ard Biesheuvel 1549fb607b ArmPkg/DefaultExceptionHandlerLib: use deadloop rather than ASSERT
The default exception handler, which is essentially the one that is invoked
for unexpected exceptions, ends with an ASSERT (FALSE), to ensure that
execution halts after dumping the CPU state. However, ASSERTs are compiled
out in RELEASE builds, and since we simply return to wherever the ELR is
pointing, we will not make any progress in case of synchronous aborts, and
the same exception will be taken again immediately, resulting in the string
'Exception at 0x....' to be printed over and over again.

So use an explicit deadloop instead.
