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;
