In above code block,
"If ((Attributes & (~(DEV_SUPPORTED_ATTRIBUTES))) != 0)" is TRUE,
the Attributes must be not 0. So we can remove the redundant

Ruiyu Ni 736c436e53 MdeModulePkg/PciBus: Fix system hang when no PCI Option ROM exists
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1394

When there is no PCI option ROM exists, today's logic still creates
virtual BAR for option ROM using Length = 0, Alignment = (-1).
It causes the final MEM32 alignment requirement is as big as
0xFFFFFFFF_FFFFFFFF.

The patch fixes this issue by only creating virtual BAR for option
ROM when there is PCI option ROM.

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:
20f6f144d3a8 ("Marvell/Drivers: XenonDxe: Allow overriding base clock
frequency")

Hao Wu bd224a5dad MdeModulePkg/NvmExpressPei: Refine data buffer & len check in PassThru

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.

and map the buffer with EfiPciIoOperationBusMasterCommonBuffer,
then the unmap and map operations can be removed.

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.

Star Zeng aa4240edff MdeModulePkg SataControllerDxe: Calculate ChannelCount based on PI value
Current code calculates ChannelCount based on CAP(NP) value.
It only works when the ports implemented number are <= CAP(NP),
for example, platform has CAP(NP) = 5 (means 6 ports) and ports
implemented are 0, 1, 2, 3, 4 and 5.

But we have some platform that has CAP(NP) = 1 (means 2 ports) and
ports implemented are 1 and 2, and has no port 0 implemented, then
current code does not work.

This patch updates the code to calculate ChannelCount based on PI value.

Star Zeng 72750e3bf9 MdeModulePkg UsbBusPei: Fix wrong buffer length used to read hub desc
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=973

Bug 973 just mentions UsbBusDxe, but UsbBusPei has similar issue.

HUB descriptor has variable length.
But the code uses stack (HubDescriptor in PeiDoHubConfig) with fixed
length sizeof(EFI_USB_HUB_DESCRIPTOR) to hold HUB descriptor data.
It uses hard code length value (12) for SuperSpeed path.
And it uses HubDesc->Length for none SuperSpeed path, then there will
be stack overflow when HubDesc->Length is greater than
sizeof(EFI_USB_HUB_DESCRIPTOR).

The patch updates the code to use a big enough buffer to hold the
descriptor data.

HUB descriptor has variable length.
But the code uses stack (HubDesc in UsbHubInit) with fixed length
sizeof(EFI_USB_HUB_DESCRIPTOR) to hold HUB descriptor data.
It uses hard code length value (32 that is greater than
sizeof(EFI_USB_HUB_DESCRIPTOR)) for SuperSpeed path, then there will
be stack overflow when IOMMU is enabled because the Unmap operation
will copy the data from device buffer to host buffer.
And it uses HubDesc->Length for none SuperSpeed path, then there will
be stack overflow when HubDesc->Length is greater than
sizeof(EFI_USB_HUB_DESCRIPTOR).

The patch updates the code to use a big enough buffer to hold the

The definition EFI_USB_SUPER_SPEED_HUB_DESCRIPTOR is wrong (HubDelay
field should be UINT16 type) and no code is using it, the patch
removes it.

Ruiyu Ni dd190645eb MdeModulePkg/UsbKb: fix shell edit cannot read '!@#$%^&*' characters
Commit 5563281fa2
* ShellPkg/[hex]edit: use SimpleTextInEx to read console
changes shell edit and hexedit to read input through SimpleTextInEx.

It exposes a issue in UsbKeyboard driver:
Per UEFI Spec,
When interpreting the data from this function (ReadKeyStrokeEx), it
should be noted that if a class of printable characters that are
normally adjusted by shift modifiers (e.g. Shift Key + "f" key) would
be presented solely as a KeyData.Key.UnicodeChar without the
associated shift state. So in the previous example of a Shift Key +
"f" key being pressed, the only pertinent data returned would be
KeyData.Key.UnicodeChar with the value of "F".

UsbKeyboard driver does convert Shift Key + "f" to "F" without the
shift state. But it doesn't do the conversion for all printable
characters, e.g.: Shift Key + "1" --> "!".

The root cause is today's logic to check whether a character is
printable or not is as below:
  if ((KeyDescriptor->AffectedAttribute & EFI_AFFECTED_BY_CAPS_LOCK)
      != 0) {

So it only converts Shift + "a"-"z", but doesn't for Shift + "0"-"9",
and Shift + "["...

The patch updates the check logic as below to fix the issue:
  if ((KeyDescriptor->Unicode != CHAR_NULL) &&
      (KeyDescriptor->ShiftedUnicode != CHAR_NULL) &&
      (KeyDescriptor->Unicode != KeyDescriptor->ShiftedUnicode)) {

The above check is TRUE when the character is printable and
it's *really* affected by Shift key.

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.

Ruiyu Ni 06e2409667 MdeModulePkg/UsbMass: Retry CMD for MediaChanged sense key
When a USB device reports failure for a CMD and REQUEST SENSE returns
Media Changed key, UsbBootExecCmdWithRetry() stops to retry CMD and
returns EFI_MEDIA_CHANGED to caller.

For this case, the CMD should be retried until success, getting
NoMedia sense key or timeout.
The patch updates UsbBootExecCmdWithRetry() to follow the above
rule so EFI_MEDIA_CHANGED is no longer returned.

UsbBootDetectMedia() is updated accordingly.

Because UsbBootGetParams() is called for new plugged USB storage,
and some USB storage devices may report Media Changed key,
UsbBootGetParams() is updated to treat it as a Success.
This change could fix the issue that some USB storage devices
cannot be detected.

The commit caused EFI_MEDIA_CHANGED status returned from

But that fix exposes another issue:
When issuing ReadCapacity command to certain USB key

returns STALL error and RequestSense command returns media changed
sense data. (Most of the USB keys return SUCCESS for ReadCapacity
command after hot-plug.)

Ruiyu Ni 6461344c31 MdeModulePkg/UsbMass: Fix hot-plug USB CDROM can't be recognized
In below calling stack:
UsbBootIsUnitReady()
 UsbBootExecCmdWithRetry()
  UsbBootExecCmd()
    UsbBootRequestSense()
When USB CDROM is hot-plugged, UsbBootRequestSense() retrieves sense
key (6 = UnitAttention), additional sense code (29h = Power ON).
But it wrongly maps such sense data to Device Error status.
It causes UsbBootExecCmd() executed again.
In the second time call to UsbBootExecCmd(), UsbBootRequestSense()
retrieves sense key (6 = UnitAttention), additional sense code
(28h = media changed).

The above analysis explains why hot-plug USB CDROM cannot be
recognized after below commit:
SHA1 a662afb5b0
* MdeModulePkg/UsbStorage: Fix "map -r" cannot detect media change,
which removes the media changed status check in UsbBootDetectMedia().

The proper fix to this problem is to map the ASC (additional sense
code 29h) properly to success status so that no second call to
UsbBootExecCmd() is made.

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.

Michael D Kinney 8d92f819f5 MdeModulePkg/UsbMassStorageDxe: Check Get Max LUN status/value
https://bugzilla.tianocore.org/show_bug.cgi?id=767

If a USB Mass Storage device does not support the Get
Max LUN command, then the USB I/O Protocol ControlTransfer()
service may return an error.  If an error is returned for
this command, then assume that the device does not support
multiple LUNs and return a maximum LUN value of 0.

The USB Mass Storage Class Specification states that a
maximum LUN value larger than 0x0F is invalid.  Add
a check to make sure this maximum LUN value is in this
valid range, and if it is not, then assume that the
device does not support multiple LUNs and return a
maximum LUN value of 0.

This change improves compatibility with USB FLASH drives
that do not support the Get Max LUN command or return
an invalid maximum LUN value.

Michael D Kinney b4e96b82b4 MdeModulePkg/UsbBusDxe: Add UsbControlTransfer() error check
https://bugzilla.tianocore.org/show_bug.cgi?id=767

The USB I/O Protocol function ControlTransfer() has a DataLength
parameter that specifies the size of the Data buffer.  The
UsbBusDxe module implements the USB I/O Protocol using the
services of the USB2 Host Controller Protocol.  The DataLength
parameter in the USB2 Host Controller Protocol ControlTransfer()
service is an IN OUT parameter so the number of bytes actually
transferred is returned.  Since the USB I/O Protocol
ControlTransfer() service can not return the number of bytes
actually transferred, the only option if the number of bytes
actually transferred is less than the number of bytes requested
is to return EFI_DEVICE_ERROR.

The change fixes an issue with a USB mass storage device that
responds with 0 bytes to the Get MAX LUN command.

Michael D Kinney d8030c2ae0 MdeModulePkg/UsbMassStorageDxe: Enhance Request Sense Handling
https://bugzilla.tianocore.org/show_bug.cgi?id=782

Update the Request Sense check for the Request Sense Key of
USB_BOOT_SENSE_UNIT_ATTENTION.  For this Sense Key, the
Additional Sense Key to EFI_STATUS mappings are:

USB_BOOT_ASC_MEDIA_CHANGE -> EFI_MEDIA_CHANGE
USB_BOOT_ASC_NOT_READY    -> EFI_NOT_READY
USB_BOOT_ASC_NO_MEDIA     -> EFI_NOT_READY
All others                -> EFI_DEVICE_ERROR

A USB flash drive is returning Request Sense Key of
USB_BOOT_SENSE_UNIT_ATTENTION and an Additional Sense Key of
USB_BOOT_ASC_NO_MEDIA for a few seconds before returning an
Additional Sense Key of USB_BOOT_ASC_MEDIA_CHANGE.

The current logic treats this initial Request Sense info as an
error and reties the command 5 times before failing completely.

With this change the USB Flash Drive works correctly.

https://bugzilla.tianocore.org/show_bug.cgi?id=766

Update logic to not return an error from UsbBootRequestSense()

It is legal for a USB mass storage device to respond to a
Request Sense command with a SenseKey of
USB_BOOT_SENSE_NO_SENSE and an Additional Sense
Code of USB_BOOT_ASC_NO_ADDITIONAL_SENSE_INFORMATION.

This is described in Section 3.3 of the Universal Serial
Bus Mass Storage Specification For Bootability:

http://www.usb.org/developers/docs/devclass_docs/usb_msc_boot_1.0.pdf

The previous logic returned an error of EFI_NO_RESPONSE

Ruiyu Ni b5cbef4eff MdeModulePkg/PciBus: Fix bug that doesn't produce BusOverride
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.

Laszlo Ersek 76fd5a660d MdeModulePkg/AtaAtapiPassThru: disable only BM-DMA at ExitBootServices()
Clearing I/O port decoding in the PCI command register at
ExitBootServices() breaks IDE boot in Windows, on QEMU's "pc" (i440fx)
machine type. (AHCI boot on "q35" is unaffected.) Windows seems repeatedly
stuck, apparently waiting for a timeout of sorts.

This is arguably a Windows bug; a native OS driver should not expect the
firmware to leave the PCI command register in any particular state.

Strictly speaking, we only need to disable BM-DMA at ExitBootServices(),
in order to abort pending transfers to/from RAM, which is soon to be owned
by the OS. BM-DMA is also the only bit that's explicitly named by the UEFI
Driver Writers' Guide, for clearing at ExitBootServices().

I've verified that clearing only BM-DMA fixes the issue (boot time) on
i440fx, and does not regress q35/AHCI.
