Ruiyu Ni fff2623cc2 MdeModulePkg/PciBus: Avoid hang when BUS pad resource is not in top
PciScanBus() assumes the GetResourcePadding() puts BUS descriptor
in the very beginning, if it's not, the Descriptors will be updated
to point to middle of the pool buffer, which can cause
FreePool(Descriptors) hang in DEBUG image.
No functionality impact to RELEASE image.

Star Zeng 958a81813b MdeModulePkg Xhci: Also RecoverHaltedEndpoint for BABBLE_ERROR
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=644

According to XHCI spec:
4.10.2.1 Stall Error

4.10.2.4 Babble Detected Error
When a device transmits more data on the USB than the host controller
is expecting for a transaction, it is defined to be babbling.
In general, this is called a Babble Error. When a device sends more
data than the TD Transfer Size bytes (TD Babble), unexpected activity
that persists beyond a specified point in a (micro)frame (Frame Babble),
or a packet greater than Max Packet Size (Packet Babble), the host
controller shall set the Babble Detected Error in the Completion Code
field of the TRB, generate an Error Event, and halt the endpoint
(refer to Section 4.10.2.1).

This patch is to also check for EFI_USB_ERR_BABBLE error returned as
a TransferResult and then proceed to XhcRecoverhaltedEndPoint.

Hao Wu 5f5bba14b6 MdeModulePkg/NvmExpressDxe: Handle timeout for blocking PassThru req
https://bugzilla.tianocore.org/show_bug.cgi?id=433

When a blocking NVMe PassThru request experiences timeout, the current
codes in function NvmExpressPassThru() do not abort the timeout request
while advancing synchronous Submission Queue tail. Therefore, it is
possible to submit a new blocking PassThru request when the synchronous
Submission Queue is full.

The commit adds logic to abort the timeout request by resetting the NVMe
controller when a timeout occurs for a blocking PassThru request.

Ard Biesheuvel 1fb805b1eb MdeModulePkg/AtaAtapiPassThru: relax PHY detect timeout
The SATA spec mandates that link detection by the PHY completes within
10 ms after receiving a reset signal. However, there is no obligation
to uphold this requirement at the driver end as strictly as we do, and
as it turns out, some combinations of host and device (e.g., Samsung
850 EVO connected to a LeMaker Cello) are only borderline compliant,
which means the device is not detected reliably.

So let's allow for a bit of margin, and increase the PHY detect timeout
value to 15 ms.

Ruiyu Ni b659b503fa MdeModulePkg/UsbBus: Fix system hang when failed to uninstall UsbIo
When "reconnect -r" is typed in shell, UsbFreeInterface() is called
to uninstall the UsbIo and DevicePath. But When a UsbIo is opened
by a driver and that driver rejects to close the UsbIo in Stop(),
the uninstall doesn't succeed.
But UsbFreeInterface () frees the DevicePath memory without check
whether the uninstall succeeds.
It leads to the DXE core database contain a DevicePath instance but
that instance's memory is freed.
Assertion happens when someone calls InstallProtocol(DevicePath)
because the InstallProtocol() checks all DevicePath instance to
find whether the same one exits in database.

We haven't seen any USB device driver which rejects to close UsbIo
in Stop(), but it's very likely.

we should capture the status of updating completion queue head doorbell

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

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;

Ruiyu Ni 29dbdcabf9 MdeModulePkg/IncompatiblePci: Use MAX_UINTN to match any IDs
When the VendorId/DeviceId/RevisionId/SubsystemVendorId
/SubsystemDeviceId is MAX_UINTN, IncompatiblePciDeviceSupport
driver doesn't use it to match any IDs.
The patch fixes this bug.
Since PciBus driver always calls IncompatiblePciDeviceSupport
using IDs read from HW, MAX_UINTN is never passed to this
driver.

PCI_ACPI_UNUSED (0) --> 0
PCI_BAR_ALL (0xFF) --> MAX_UINT64
PCI_BAR_NOCHANGE (0) --> 0
PCI_BAR_EVEN_ALIGN --> EVEN_ALIGN (local definition)

Since the PciBus driver was updated to accept Spec defined values
in previous commit, the above replacements don't impact
functionality.

Ruiyu Ni 8a93fa1efb MdeModulePkg/PciBus: Accept Spec values as BarIndex and Alignment
PI spec IncompatiblePciSupport part defines (UINT64)-1 as all BARs
and 0 to use existing alignment. PciBus driver didn't accept these
values. It treated 0xFF as all BARs and 0xFFFFFFFFFFFFFFFFULL to use
existing alignment.
The patch changes the code to still accept old values while also
accept values defined in PI spec. So that the driver can provide
backward compatibility and follow spec.

using PCI_BAR_ALL is like to match any BAR not BAR 0, it's more
