These 2 patches introduces the Compute Express Link (CXL) Specificition registers definitions to the MDE.
The Cxl11.h has the actual register definitions of the CXL Specification Revision 1.1; and the Cxl.h is the main header file to include all versions of the CXL register definitions.

Register definitions from chapter 7 of Compute Express Link Specification
Revision 1.1 are ported into the new Cxl11.h.
The CXL Flex Bus registers are based on the PCIe Extended Capability
DVSEC structure header, led to the inclusion of upgraded Pci.h.

Hi Arshaf,
1) Pci.h - Copyright should be updated to 2020
2) Why is define for CXL_DVSEC_VENDOR_ID listed on its own
in Cxl.h? Was this added to the standard after the CXL 1.1
specs?
3) There are a few minor formatting issues with the field
indentations for some of the bitfield structs. One example:
typedef union {
struct {
UINT16 CacheEnable : 1; // bit 0
UINT16 IoEnable : 1; // bit 1
UINT16 MemEnable : 1; // bit 2
UINT16 CxlSyncBypassEnable : 1; // bit 3
UINT16 DriftBufferEnable : 1; // bit 4
UINT16 Reserved : 3; // bit 5..7
UINT16 CxlCorrectableProtocolIdFramingError : 1; // bit 8
UINT16 CxlUncorrectableProtocolIdFramingError : 1; // bit 9
UINT16 CxlUnexpectedProtocolIdDropped : 1; // bit 10
UINT16 Reserved2 : 5; // bit 11..15
}Bits;
UINT16 Uint16;
} CXL_1_1_DVSEC_FLEX_BUS_PORT_STATUS;
Should be:
typedef union {
struct {
UINT16 CacheEnable : 1; // bit 0
UINT16 IoEnable : 1; // bit 1
UINT16 MemEnable : 1; // bit 2
UINT16 CxlSyncBypassEnable : 1; // bit 3
UINT16 DriftBufferEnable : 1; // bit 4
UINT16 Reserved : 3; // bit 5..7
UINT16 CxlCorrectableProtocolIdFramingError : 1; // bit 8
UINT16 CxlUncorrectableProtocolIdFramingError : 1; // bit 9
UINT16 CxlUnexpectedProtocolIdDropped : 1; // bit 10
UINT16 Reserved2 : 5; // bit 11..15
}Bits;
UINT16 Uint16;
} CXL_1_1_DVSEC_FLEX_BUS_PORT_STATUS;
4) The following structure that provides a log looks a little odd
because code that access the log array would have to use
HeaderLog.HeaderLog[Index].
typedef struct {
CXL_1_1_UNCORRECTABLE_ERROR_STATUS HeaderLog[16];
} CXL_HEADER_LOG;
typedef struct {
CXL_1_1_UNCORRECTABLE_ERROR_STATUS UncorrectableErrorStatus; // offset 0
CXL_1_1_UNCORRECTABLE_ERROR_MASK UncorrectableErrorMask; // offset 4
CXL_1_1_UNCORRECTABLE_ERROR_SEVERITY UncorrectableErrorSeverity; // offset 8
CXL_CORRECTABLE_ERROR_STATUS CorrectableErrorStatus; // offset 12
CXL_CORRECTABLE_ERROR_MASK CorrectableErrorMask; // offset 16
CXL_ERROR_CAPABILITIES_AND_CONTROL ErrorCapabilitiesAndControl; // offset 20
CXL_HEADER_LOG HeaderLog; // offset 24
} CXL_1_1_RAS_CAPABILITY_STRUCTURE;
If this was changed to the following, it may be easier
to use and understand:
typedef struct {
CXL_1_1_UNCORRECTABLE_ERROR_STATUS UncorrectableErrorStatus; // offset 0
CXL_1_1_UNCORRECTABLE_ERROR_MASK UncorrectableErrorMask; // offset 4
CXL_1_1_UNCORRECTABLE_ERROR_SEVERITY UncorrectableErrorSeverity; // offset 8
CXL_CORRECTABLE_ERROR_STATUS CorrectableErrorStatus; // offset 12
CXL_CORRECTABLE_ERROR_MASK CorrectableErrorMask; // offset 16
CXL_ERROR_CAPABILITIES_AND_CONTROL ErrorCapabilitiesAndControl; // offset 20
CXL_1_1_UNCORRECTABLE_ERROR_STATUS HeaderLog[16]; // offset 24
} CXL_1_1_RAS_CAPABILITY_STRUCTURE;
Thanks,
Mike

Missed it, will change this.

Yes, it was added after the CXL1.1 specs was published. This is made backward compatible for the CXL1.1 DVSEC Vendor IDs, and also applicable for CXL 2.0 in future; hence I added this in the Cxl.h.

Good catch, will fix, I used a Python script to generate these structures and happen to miss the indentation for the second level.
