Hao Wu 95ad8f7f6a MdeModulePkg/Ufs: Wait fDeviceInit be cleared by devices during init
In the origin codes, the host sets the fDeviceInit flag to initiate device
initialization, but does not check whether the device resets this flag
to indicate the device initialization is completed.

Details can be referred at UFS 2.0 Spec Section 14.2 - Flags.

Hao Wu a2617ed627 MdeModulePkg/UsbBotPei: Fix undefined behavior in signed left shift
In function PeiUsbReadCapacity(), the following expression:
LastBlock = (Data.LastLba3 << 24) |
  (Data.LastLba2 << 16) |
  (Data.LastLba1 << 8) |
  Data.LastLba0;

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

will involve undefined behavior in signed left shift operations.

Since Data.LastLbaX is of type UINT8, they 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
might incur potential issues.

This commit will add an explicit UINT32 type cast for Data.LastLba3 to
refine the codes.

Hao Wu da117dda23 MdeModulePkg/UfsBlkIoPei: Fix undefined behavior in signed left shift

Suman Prakash f2333c707d MdeModulePkg/NvmExpressDxe: Memory leak fix in async code flow
For async commands, the buffer allocated for Prp list is
not getting freed, which will cause memory leak for async

with custom application to send multiple read write commands
were resulting in decrease of available memory page in memmap,
which eventually resulted in system hang. Hence freeing

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;

Ard Biesheuvel 8b78de74dc MdeModulePkg/NonDiscoverablePciDevice: add missing cast and EFIAPI modifiers
Add missing EFIAPI modifiers to the functions that are exposed via the
PCI I/O protocol.

At the same time, add a missing UINT8 cast which breaks the build on
Visual Studio.

Ard Biesheuvel a42e6d448d MdeModulePkg: implement generic PCI I/O driver for non-discoverable devices
This implements support for non-discoverable PCI compatible devices, i.e,
devices that are not on a PCI bus but that can be controlled by generic PCI
drivers in EDK2.

This is implemented as a UEFI driver, which means we take full advantage
of the UEFI driver model, and only instantiate those devices that are
necessary for booting.

Care is taken to deal with DMA addressing limitations: DMA mappings and
allocations are moved below 4 GB if the PCI driver has not informed us
that the device being driven is 64-bit DMA capable. DMA is implemented as
coherent, support for non-coherent DMA is implemented by a subsequent patch.

Feng Tian d9077743b6 MdeModulePkg/Ehci: don't clear port status bits during init
Port status bits are clear in original code, so no enumeration
takes place.
Changing this to prevent the status bits from being cleared
allows enumeration to proceed normally.

Marcin Wojtas 6052a15f4a MdeModulePkg/AtaAtapiPassThru: Ensure GHC.AE bit is always set in Ahci
According to AHCI Spec 1.3 GHC.AE bit description:
"The implementation of this bit is dependent upon the value of the
CAP.SAM bit. If CAP.SAM is '0', then GHC.AE shall be read-write and shall
have a reset value of '0'. If CAP.SAM is '1', then AE shall be read-only
and shall have a reset value of '1'."

Being in AhciMode, for proper operation it is required, that GHC.AE bit
is always set, before any other AHCI registers are written to. Current
AhciMode implementation, both in AhciReset() and AhciModeInitialization()
functions, set GHC.AE bit only depending on 'CAP.SAM == 0' condition,
assuming (according to the AHCI spec), that otherwise it has to be set
anyway. It may however happen, that even if 'CAP.SAM == 1', GHC.AE
requires updating by software.

This patch enables in AhciMode setting GHC.AE in case its initial value
is '0'. It fixes AHCI support for Marvell Armada 70x0 and 80x0 SoC
families. The change is transparent to all other platforms.

Feng Tian 26b8501280 MdeModulePkg/Xhci: Add 10ms delay before sending SendAddr cmd to dev
We send ADDRESS DEVICE CMD in XhcInitializeDeviceSlot(), which will
cause XHC issue a USB SET_ADDRESS request to the USB Device.

According to USB spec, there should have a 10ms delay before this
operation after resetting a given port.

But in original code, there is a possible path which may have no such
10ms delay:
UsbHubResetPort()->UsbHubSetPortFeature()->Stall(20)->UsbHubGetPortSt
atus()->XhcPollPortStatusChange()->(if RESET_C bit is set)->
XhcInitializeDeviceSlot()->(if RESET_C bit is set)->Stall(10)

So this patch is used to fix above issue.

Ruiyu Ni 4ab04a72f5 MdeModulePkg/PciSioSerial: Fix a bug that wrongly produces 2 UARTs
When PciSioSerial is firstly started with a non-NULL remaining
device path, the UART instance is created using the parameters
specified in the remaining device path. Later when the driver
is started again on the same UART controller with NULL remaining
device path, the correct logic is to directly return SUCCESS
instead of current buggy implementation which wrongly produces
another UART using the default parameters.

The bug causes two UARTs are created when the UART is configured
in 57600 baud rate.
