Albecki, Mateusz 206783aa7f MdeModulePkg/SdMmcPciHcDxe: Remove clock stop from HS200 switch
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2218

Stopping the SD clock before switching host controller
bus timing is only necessary if preset value enable is
set in host controller. Code that performs switch to
HS200 doesn't check this condition right now and we also
don't do the SD clock stop before any other bus timing switch
in host controller. Since the driver is generally not ready to support
host controller with preset value enable set we removed this
code.

Albecki, Mateusz adec1f5deb MdeModulePkg/SdMmcHcDxe: Implement revision 3 of SdMmcOverrideProtocol
https://bugzilla.tianocore.org/show_bug.cgi?id=1882

Implement support for GetOperatingParamters notify phase
in SdMmcHcDxe driver. GetOperatingParameters notify phase
is signaled before we start card detection and initialization.
Code has been updated for both eMMC and SD card controllers to
take into consideration those new parameters. Initialization process
has been divided into 2 steps. In the first step we bring the link
up to the point where we can get card identification data(Extended
CSD in eMMC case and SWITCH command response in SD card case). This
data is later used along with controller capabilities and operating
parameters passed in GetOperatingParameters phase to choose preferred
bus settings in GetTargetBusSettings function. Those settings are later
on to start bus training to high speeds. If user passes incompatible
setting with selected bus timing driver will assume it's standard behavior
with respect to that setting. For instance if HS400 has been selected as a
target bus timing due to card and controller support bus width setting of
4 and 1 bit won't be respected and 8 bit setting will be chosen instead.

Tests on Marvell boards were also performed by Marcin Wojtas
<mw@semihalf.com>:

https://edk2.groups.io/g/devel/message/42999

Board 1 (out of tree): SD - OK, MMC - OK
Board 2: (Armada80x0McBin): SD - OK, MMC - OK
Board 3: (Armada70x0Db): SD - problems, MMC - OK

Please note that the problem on Armada70x0Db SD devices are introduced by
adding new types of SD bus modes, a subsequent patch within edk2-platforms
repository will be proposed to address it.

Laszlo Ersek e5b4d825af MdeModulePkg/PciBusDxe: catch unimplemented extended config space reads
When assigning a physical PCIe device to a QEMU/KVM guest, PciBusDxe may
find that the extended config space is not (fully) implemented. In
LocatePciExpressCapabilityRegBlock(), "CapabilityEntry" may be read as
0xFFFF_FFFF at a given config space offset, after which the loop gets
stuck spinning on offset 0xFFC (the read at offset 0xFFC returns
0xFFFF_FFFF most likely as well).

Another scenario (not related to virtualization) for triggering the above
is when a Conventional PCI bus -- exposed by a PCIe-to-PCI bridge in the
topology -- intervenes between a PCI Express Root Port and a PCI Express
Endpoint. The Conventional PCI bus limits the accessible config space of
the PCI Express Endpoint, even though the endpoint advertizes the PCI
Express capability. Here's a diagram, courtesy of Alex Williamson:

  [PCIe Root Port]--[PCIe-to-PCI]--[PCI-to-PCIe]--[PCIe EP]
                              ->|  |<- Conventional PCI bus

Catch reads of 0xFFFF_FFFF in LocatePciExpressCapabilityRegBlock(), and
break out of the scan with a warning message. The function will return
EFI_NOT_FOUND.

Ray Ni 0fa92d5839 MdeModulePkg/PciBus: Fix a bug PPB MEM32 BAR isn't restored sometimes
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1505

When a device under PPB contains option ROM but doesn't require 32bit
MMIO, ProgrameUpstreamBridgeForRom() cannot correctly restore the
PPB MEM32 RANGE BAR. It causes the 32bit MMIO conflict which may
cause system hangs in boot.

The root cause is when ProgrameUpstreamBridgeForRom() calls
ProgramPpbApperture() to restore the PPB MEM32 RANGE BAR, the
ProgramPpbApperture() skips to program the BAR when the resource
length is 0.

This patch fixes this issue by not calling ProgramPpbApperture().
Instead, it directly programs the PPB MEM32 RANGE BAR.

Ruiyu Ni 0176af142e MdeModulePkg/PciBus: Shadow option ROM after BARs are programmed
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1376

Today's implementation reuses the 32bit MMIO resource requested by
all PCI devices MMIO BARs when shadowing the option ROM.
Take a simple example, a system has only one PCI device. It requires
8MB 32bit MMIO and contains a 4MB option ROM. Today's implementation
only requests 8MB (max of 4M and 8M) 32bit MMIO from
PciHostBridgeResourceAllocation protocol. Let's assume the MMIO range
[3GB, 3GB+8MB) is allocated. The 3GB base address is firstly
programmed to the option ROM BAR for option ROM shadow. Then the
option ROM decoding is turned off and 3GB base address is programmed
to the 32bit MMIO BAR.

It doesn't cause issues when the device doesn't request too much
MMIO.
But when the device contains a 64bit MMIO BAR which requests 4GB MMIO
and a 4MB option ROM. Let's assume [3GB, 3GB+8MB) 32bit MMIO range is
allocated for the option ROM. When the option ROM is being shadowed,
64bit MMIO BAR is programmed to value 0, which means [0, 4GB) MMIO is
given to the 64bit BAR.
The range overlaps with the option ROM range which may cause the
device malfunction (e.g.: option ROM cannot be read out) when the
device has two separate decoders: one for MMIO BAR, the other for
option ROM.

The patch requests dedicated MEM32 resource for Option ROMs and
moves the Option ROM shadow logic after all MMIO BARs are programmed.
The MMIO BAR setting to 0 when shadowing Option ROM is also skipped
because the MMIO BAR already contains the correct value.

Marcin Wojtas 7f3b0bad4b MdeModulePkg/SdMmcPciHcDxe: Allow overriding base clock frequency
Some SdMmc host controllers are run by clocks with different
frequency than it is reflected in Capabilities Register 1.
It is allowed by SDHCI specification ver. 4.2 - if BaseClkFreq
field value of the Capability Register 1 is zero, the clock
frequency must be obtained via another method.

Because the bitfield is only 8 bits wide, a maximum value
that could be obtained from hardware is 255MHz.
In case the actual frequency exceeds 255MHz, the 8-bit BaseClkFreq
member of SD_MMC_HC_SLOT_CAP structure occurs to be not sufficient
to be used for setting the clock speed in SdMmcHcClockSupply
function.

This patch adds new UINT32 array ('BaseClkFreq[]') to
SD_MMC_HC_PRIVATE_DATA structure for specifying
the input clock speed for each slot of the host controller.
All routines that are used for clock configuration are
updated accordingly.

This patch also adds new IN OUT BaseClockFreq field
in the Capability callback of the SdMmcOverride,
protocol which allows to update BaseClkFreq value.

The patch reuses original commit from edk2-platforms:

Hao Wu 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 ebb6c7633b.
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.

NvmExpressPassThru(), it will only accept driver internal IO queue

Ard Biesheuvel 1a3bee2082 MdeModulePkg/NonDiscoverablePciDeviceDxe: expose unique B/D/F identifiers
Currently, the implementation of EFI_PCI_IO_PROTOCOL::GetLocation()
in NonDiscoverablePciDeviceDxe returns the same set of dummy values
for each instance of the NON_DISCOVERABLE_DEVICE protocol that it
attaches itself to. However, this turns out to be causing problems
in cases where software (such as the ARM Compliance Test Suite [ACS])
attempts to use these values to uniquely identify controllers, since
the collisions create ambiguity in this regard.

So let's modify GetLocation() to return an arbitrary bus/device tuple
on segment 0xff instead. This is guaranteed not to clash with other
non-discoverable PCI devices, and highly unlikely to clash with real
PCIe devices.

Laszlo Ersek c3d5d800d7 MdeModulePkg/EhciDxe: fix host controller reset condition in BindingStart
Commit 09943f5ecc ("MdeModulePkg: Skip to manage usb debug port in EDKII
EHCI driver if it's used by usb debug port driver", 2012-04-28) made the
host controller reset in EhcDriverBindingStart() conditional. The intent
was to avoid the reset when
- one of the USB ports on the host controller was a Debug Port, AND
- the Debug Port was in use.

This translates to the following positive condition: reset the controller
only if:
- no USB port on the host controller is a Debug Port, OR
- the Debug Port is not in use.

Commit 09943f5ecc failed to implement the first subcondition, and thus
the result is too strict now (for resetting the host controller). Relax it
to the correct condition.

This issue was found by Steven Shi on QEMU. QEMU's EHCI device model does
not have a Debug Port. In repeated disconnect / connect cycles, the
controller is never reset in EhcDriverBindingStart(), therefore the
devices on the controller are never re-enumerated after a disconnect.

Ruiyu Ni 983f5abb9a MdeModulePkg/PciBus: Restrict one VGA per HostBridge not Segment
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1109

Today's restriction of VGA device is to have only one VGA device
enabled per PCI segment. It's not correct because several segments
may share one IO / MMIO address space.
We should restrict to have one VGA per Host Bridge because each
Host Bridge has its only IO / MMIO address space.

current code does not work.

Heyi Guo 74d0a339b8 MdeModulePkg/PciHostBridgeDxe: Add support for address translation
PCI address translation is necessary for some non-x86 platforms. On
such platforms, address value (denoted as "device address" or "address
in PCI view") set to PCI BAR registers in configuration space might be
different from the address which is used by CPU to access the
registers in memory BAR or IO BAR spaces (denoted as "host address" or
"address in CPU view"). The difference between the two addresses is
called "Address Translation Offset" or simply "translation", and can
be represented by "Address Translation Offset" in ACPI QWORD Address
Space Descriptor (Offset 0x1E). However UEFI and ACPI differs on the
definitions of QWORD Address Space Descriptor, and we will follow UEFI
definition on UEFI protocols, such as PCI root bridge IO protocol and
PCI IO protocol. In UEFI 2.7, "Address Translation Offset" is "Offset
to apply to the Starting address to convert it to a PCI address". This
means:

1. Translation = device address - host address.

2. PciRootBridgeIo->Configuration should return CPU view address, as
well as PciIo->GetBarAttributes.

Summary of addresses used in protocol interfaces and internal
implementations:

1. *Only* the following protocol interfaces assume Address is Device
   Address:
(1). PciHostBridgeResourceAllocation.GetProposedResources()
     Otherwise PCI bus driver cannot set correct address into PCI
     BARs.
(2). PciRootBridgeIo.Mem.Read() and PciRootBridgeIo.Mem.Write()
(3). PciRootBridgeIo.CopyMem()
UEFI and PI spec have clear statements for all other protocol
interfaces about the address type.

2. Library interfaces and internal implementation:
(1). Base and Limit in PCI_ROOT_BRIDGE_APERTURE are device address.
     It is easy to check whether the address is below 4G or above 4G.
(2). Addresses in PCI_ROOT_BRIDGE_INSTANCE.ResAllocNode are host
     address, for they are allocated from GCD.
(3). Address passed to PciHostBridgeResourceConflict is host address,
     for it comes from PCI_ROOT_BRIDGE_INSTANCE.ResAllocNode.

RESTRICTION: to simplify the situation, we require the alignment of
Translation must be larger than any BAR alignment in the same root
bridge, so that resource allocation alignment can be applied to both
device address and host address.

Heyi Guo 9a77210b43 MdeModulePkg/NvmExpressDxe: fix error status override
Commit f6b139b added return status handling to PciIo->Mem.Write.
However, the second status handling will override EFI_DEVICE_ERROR
returned in this branch:

  //
  // Check the NVMe cmd execution result
  //
  if (Status != EFI_TIMEOUT) {
    if ((Cq->Sct == 0) && (Cq->Sc == 0)) {
      Status = EFI_SUCCESS;
    } else {
      Status = EFI_DEVICE_ERROR;
               ^^^^^^^^^^^^^^^^

Since PciIo->Mem.Write will probably return SUCCESS, it causes
NvmExpressPassThru to return SUCCESS even when DEVICE_ERROR occurs.
Callers of NvmExpressPassThru will then continue executing which may
cause further unexpected results, e.g. DiscoverAllNamespaces couldn't
break out the loop.

So we save previous status before calling PciIo->Mem.Write and restore
the previous one if it already contains error.

It's a regression of below commit:
SHA-1: 8be37a5cee
* MdeModulePkg/SecurityStubDxe: Defer 3rd party image before EndOfDxe

When PciBus driver fails to load the Option ROM, it doesn't produce
BusOverride protocol. It was a correct behavior before the above
commit. But due to the above commit, BusOverride protocol never is
produced by PciBus driver.

The patch fixes this issue using the following solution:
1. PciBus records the image device path when LoadImage fails.
2. Override.GetDriver() tries to look for the image handle using
   the stored image device path.

Per NVM Express Spec, software should notify NVME HW when shutdown
occurs.

The NVME controller requires notification for shutdown as part of
its management of internal structures. Even with FUA, failing to
notify the NVME controller to shutdown power off causes the NVME
controller to take quite some time to organize its tables on the
next power on. This time exceeds the normal timeout, so we would
fail to boot the NVME disk.

The host should set the Shutdown Notification (CC.SHN) field to 01b
to indicate a normal shutdown operation. The controller indicates
when shutdown processing is completed by updating the Shutdown Status
(CSTS.SHST) field to 10b.

data than the TD Transfer Size bytes (TD Babble), unexpected activity
that persists beyond a specified point in a (micro)frame (Frame Babble),

Some USB devices don't report data periodically through Int
Transfer. They report data only when be asked. If the TRB
is not removed from the XHCI HW, when next time HOST asks
data again, the data is reported but consumed by the previous
TRB, which results the HOST thinks data never comes.

In case of an async command if updating the submission queue tail
doorbell fails then the command will not be picked up by device and
no completion response will be created. This scenario has to be handled.
Also if we create an AsyncRequest element and insert in the async queue,
it will never receive a completion so in the timer routine this element
won't be freed, resulting in memory leak. Also in case of blocking calls
we should capture the status of updating completion queue head doorbell
register and return it to caller of PassThru.

Hao Wu 3778a4dfcd MdeModulePkg/IdeBusPei: Fix undefined behavior in signed left shift
In function ReadCapacity(), the following expression:
MediaInfo->LastBlock = (Data.LastLba3 << 24) |
  (Data.LastLba2 << 16) |
  (Data.LastLba1 << 8) |
  Data.LastLba0;

(There is also a similar case in this function.)

will involve undefined behavior in signed left shift operations.

Since Data.LastLbaX is of type UINT8, and MediaInfo->LastBlock is of type
UINTN. Therefore, Data.LastLbaX will be promoted to int (32 bits, signed)
first, and then perform the left shift operation.

According to the C11 spec, Section 6.5.7:
4 The result of E1 << E2 is E1 left-shifted E2 bit positions; vacated
  bits are filled with zeros. If E1 has an unsigned type, the value
  of the result is E1 * 2^E2 , reduced modulo one more than the
  maximum value representable in the result type. If E1 has a signed
  type and nonnegative value, and E1 * 2^E2 is representable in the
  result type, then that is the resulting value; otherwise, the
  behavior is undefined.

So if bit 7 of Data.LastLba3 is 1, (Data.LastLba3 << 24) will be out of
the range within int type. The undefined behavior of the signed left shift
will lead to a potential of setting the high 32 bits of
MediaInfo->LastBlock to 1 during the cast from type int to type UINT64
for X64 builds.

This commit will add an explicit UINT32 type cast for Data.LastLba3 to
resolve this issue.

Hao Wu 16f6922709 MdeModulePkg: Refine casting expression result to bigger size
There are cases that the operands of an expression are all with rank less
than UINT64/INT64 and the result of the expression is explicitly cast to
UINT64/INT64 to fit the target size.

An example will be:
UINT32 a,b;
// a and b can be any unsigned int type with rank less than UINT64, like
// UINT8, UINT16, etc.
UINT64 c;
c = (UINT64) (a + b);

Some static code checkers may warn that the expression result might
overflow within the rank of "int" (integer promotions) and the result is
then cast to a bigger size.

The commit refines codes by the following rules:
1). When the expression is possible to overflow the range of unsigned int/
int:
c = (UINT64)a + b;

2). When the expression will not overflow within the rank of "int", remove
the explicit type casts:
c = a + b;

3). When the expression will be cast to pointer of possible greater size:
UINT32 a,b;
VOID *c;
c = (VOID *)(UINTN)(a + b); --> c = (VOID *)((UINTN)a + b);

4). When one side of a comparison expression contains only operands with
rank less than UINT32:
UINT8 a;
UINT16 b;
UINTN c;
if ((UINTN)(a + b) > c) {...} --> if (((UINT32)a + b) > c) {...}

For rule 4), if we remove the 'UINTN' type cast like:
if (a + b > c) {...}
The VS compiler will complain with warning C4018 (signed/unsigned
mismatch, level 3 warning) due to promoting 'a + b' to type 'int'.

Hao Wu 809e2bbf41 MdeModulePkg: Refine type cast for pointer subtraction
For pointer subtraction, the result is of type "ptrdiff_t". According to
the C11 standard (Committee Draft - April 12, 2011):

"When two pointers are subtracted, both shall point to elements of the
same array object, or one past the last element of the array object; the
result is the difference of the subscripts of the two array elements. The
size of the result is implementation-defined, and its type (a signed
integer type) is ptrdiff_t defined in the <stddef.h> header. If the result
is not representable in an object of that type, the behavior is
undefined."

In our codes, there are cases that the pointer subtraction is not
performed by pointers to elements of the same array object. This might
lead to potential issues, since the behavior is undefined according to C11
standard.

Also, since the size of type "ptrdiff_t" is implementation-defined. Some
static code checkers may warn that the pointer subtraction might underflow
first and then being cast to a bigger size. For example:

UINT8  *Ptr1, *Ptr2;
UINTN  PtrDiff;
...
PtrDiff = (UINTN) (Ptr1 - Ptr2);

The commit will refine the pointer subtraction expressions by casting each
pointer to UINTN first and then perform the subtraction:

PtrDiff = (UINTN) Ptr1 - (UINTN) Ptr2;
