Enable BERR promotion. When 1, the Bus Error (BERR) signal is promoted to the Bus Initialization (BINIT) signal, and the BINIT pin is asserted on the occurrence of each Bus Error. Setting this bit has no effect if BINIT signalling is disabled. (See PAL_BUS_GET/SET_FEATURES) @param EnableMcaPromotion Bit62, Enable MCA promotion. When 1, machine check aborts (MCAs) are promoted to the Bus Error signal, and the BERR pin is assert on each occurrence of an MCA. Setting this bit has no effect if BERR signalling is disabled. (See PAL_BUS_GET/SET_FEATURES) @param EnableMcaToBinitPromotion Bit61, Enable MCA to BINIT promotion. When 1, machine check aborts (MCAs) are promoted to the Bus Initialization signal, and the BINIT pin is assert on each occurrence of an MCA. Setting this bit has no effect if BINIT signalling is disabled. (See PAL_BUS_GET/SET_FEATURES) @param EnableCmciPromotion Bit60, Enable CMCI promotion When 1, Corrected Machine Check Interrupts (CMCI) are promoted to MCAs. They are also further promoted to BERR if bit 39, Enable MCA promotion, is also set and they are promoted to BINIT if bit 38, Enable MCA to BINIT promotion, is also set. This bit has no effect if MCA signalling is disabled (see PAL_BUS_GET/SET_FEATURES) @param DisableCache Bit59, Disable Cache. When 0, the processor performs cast outs on cacheable pages and issues and responds to coherency requests normally. When 1, the processor performs a memory access for each reference regardless of cache contents and issues no coherence requests and responds as if the line were not present. Cache contents cannot be relied upon when the cache is disabled. WARNING: Semaphore instructions may not be atomic or may cause Unsupported Data Reference faults if caches are disabled. @param DisableCoherency Bit58, Disable Coherency. When 0, the processor uses normal coherency requests and responses. When 1, the processor answers all requests as if the line were not present. @param DisableDPM Bit57, Disable Dynamic Power Management (DPM). When 0, the hardware may reduce power consumption by removing the clock input from idle functional units. When 1, all functional units will receive clock input, even when idle. @param DisableBinitWithTimeout Bit56, Disable a BINIT on internal processor time-out. When 0, the processor may generate a BINIT on an internal processor time-out. When 1, the processor will not generate a BINIT on an internal processor time-out. The event is silently ignored. @param EnableEnvNotification Bit55, Enable external notification when the processor detects hardware errors caused by environmental factors that could cause loss of deterministic behavior of the processor. When 1, this bit will enable external notification, when 0 external notification is not provided. The type of external notification of these errors is processor-dependent. A loss of processor deterministic behavior is considered to have occurred if these environmentally induced errors cause the processor to deviate from its normal execution and eventually causes different behavior which can be observed at the processor bus pins. Processor errors that do not have this effects (i.e., software induced machine checks) may or may not be promoted depending on the processor implementation. @param EnableVmsw Bit54, Enable the use of the vmsw instruction. When 0, the vmsw instruction causes a Virtualization fault when executed at the most privileged level. When 1, this bit will enable normal operation of the vmsw instruction. @param EnableMcaOnDataPoisoning Bit53, Enable MCA signaling on data-poisoning event detection. When 0, a CMCI will be signaled on error detection. When 1, an MCA will be signaled on error detection. If this feature is not supported, then the corresponding argument is ignored when calling PAL_PROC_SET_FEATURES. Note that the functionality of this bit is independent of the setting in bit 60 (Enable CMCI promotion), and that the bit 60 setting does not affect CMCI signaling for data-poisoning related events. Volume 2: Processor Abstraction Layer 2:431 PAL_PROC_GET_FEATURES @param DisablePState Bit52, Disable P-states. When 1, the PAL P-state procedures (PAL_PSTATE_INFO, PAL_SET_PSTATE, PAL_GET_PSTATE) will return with a status of -1 (Unimplemented procedure). @param DisableBranchPrediction Bit47, Disable Dynamic branch prediction. When 0, the processor may predict branch targets and speculatively execute, but may not commit results. When 1, the processor must wait until branch targets are known to execute. @param DisableDynamicInsCachePrefetch Bit46, Disable DynamicInstruction Cache Prefetch. When 0, the processor may prefetch into the caches any instruction which has not been executed, but whose execution is likely. When 1, instructions may not be fetched until needed or hinted for execution. (Prefetch for a hinted branch is allowed even when dynamic instruction cache prefetch is disabled.) @param DisableDynamicDataCachePrefetch Bit45, Disable Dynamic Data Cache Prefetch. When 0, the processor may prefetch into the caches any data which has not been accessed by instruction execution, but which is likely to be accessed. When 1, no data may be fetched until it is needed for instruction execution or is fetched by an lfetch instruction. @param DisableSpontaneousDeferral Bit44, Disable Spontaneous Deferral. When 1, the processor may optionally defer speculative loads that do not encounter any exception conditions, but that trigger other implementation-dependent conditions (e.g., cache miss). When 0, spontaneous deferral is disabled. @param DisableDynamicPrediction Bit43, Disable Dynamic Predicate Prediction. When 0, the processor may predict predicate results and execute speculatively, but may not commit results until the actual predicates are known. When 1, the processor shall not execute predicated instructions until the actual predicates are known. @param NoXr1ThroughXr3 Bit42, No XR1 through XR3 implemented. Denotes whether XR1 XR3 are implemented for machine check recovery. This feature may only be interrogated by PAL_PROC_GET_FEATURES. It may not be enabled or disabled by PAL_PROC_SET_FEATURES.

This feature may only be interrogated by PAL_PROC_GET_FEATURES. It may not be enabled or disabled by PAL_PROC_SET_FEATURES. The corresponding argument is ignored. @param NoVariablePState Bit39, No Variable P-state performance: A value of 1, indicates that a processor implements techniques to optimize performance for the given P-state power budget by dynamically varying the frequency, such that maximum performance is achieved for the power budget. A value of 0, indicates that P-states have no frequency variation or very small frequency variations for their given power budget. This feature may only be interrogated by PAL_PROC_GET_FEATURES. it may not be enabled or disabled by PAL_PROC_SET_FEATURES. The corresponding argument is ignored. @param NoSimpleImpInUndefinedIns Bit38, No Simple implementation of unimplemented instruction addresses. Denotes how an unimplemented instruction address is recorded in IIP on an Unimplemented Instruction Address trap or fault. When 1, the full unimplemented address is recorded in IIP; when 0, the address is sign extended (virtual addresses) or zero extended (physical addresses). This feature may only be interrogated by PAL_PROC_GET_FEATURES. It may not be enabled or disabled by PAL_PROC_SET_FEATURES. The corresponding argument is ignored. @param NoPresentPmi Bit37, No INIT, PMI, and LINT pins present. Denotes the absence of INIT, PMI, LINT0 and LINT1 pins on the processor. When 1, the pins are absent. When 0, the pins are present. This feature may only be interrogated by PAL_PROC_GET_FEATURES. It may not be enabled or disabled by PAL_PROC_SET_FEATURES. The corresponding argument is ignored. @param FaultInUndefinedIns Bit36, No Unimplemented instruction address reported as fault. Denotes how the processor reports the detection of unimplemented instruction addresses. When 1, the processor reports an Unimplemented Instruction Address fault on the unimplemented address; when 0, it reports an Unimplemented Instruction Address trap on the previous instruction in program order. This feature may only be interrogated by PAL_PROC_GET_FEATURES. It may not be enabled or disabled by PAL_PROC_SET_FEATURES.

This control word is ordered from the longest running tests up to the shortest running tests with bit 0 controlling the longest running test. PAL may not implement all 47-bits of the test_control word. PAL communicates if a bit provides control by placing a zero in that bit. If a bit provides no control, PAL will place a one in it. PAL will have two sets of test_control bits for the two phases of the processor self-test. PAL provides information about implemented test_control bits at the hand-off from PAL to SAL for the firmware recovery check. These test_control bits provide control for phase one of processor self-test. It also provides this information via the PAL procedure call PAL_TEST_INFO for both the phase one and phase two processor tests depending on which information the caller is requesting. PAL interprets these bits as input parameters on two occasions. The first time is when SAL passes control back to PAL after the firmware recovery check. The second time is when a call to PAL_TEST_PROC is made. When PAL interprets these bits it will only interpret implemented test_control bits and will ignore the values located in the unimplemented test_control bits. PAL interprets the implemented bits such that if a bit contains a zero, this indicates to run the test. If a bit contains a one, this indicates to PAL to skip the test.

This is a wrapper function to make a PAL procedure call. Based on the Index value, this API will make static or stacked PAL call. Architected procedures may be designated as required or optional. If a PAL procedure is specified as optional, a unique return code of 0xFFFFFFFFFFFFFFFF is returned in the Status field of the PAL_CALL_RETURN structure. This indicates that the procedure is not present in this PAL implementation. It is the callerĄ¯s responsibility to check for this return code after calling any optional PAL procedure. No parameter checking is performed on the 4 input parameters, but there are some common rules that the caller should follow when making a PAL call. Any address passed to PAL as buffers for return parameters must be 8-byte aligned. Unaligned addresses may cause undefined results. For those parameters defined as reserved or some fields defined as reserved must be zero filled or the invalid argument return value may be returned or undefined result may occur during the execution of the procedure. This function is only available on IPF. @param Index - The PAL procedure Index number. @param Arg2 - The 2nd parameter for PAL procedure calls. @param Arg3 - The 3rd parameter for PAL procedure calls. @param Arg4 - The 4th parameter for PAL procedure calls. @return structure returned from the PAL Call procedure, including the status and return value. **/ PAL_CALL_RETURN EFIAPI PalCall ( IN UINT64 Index, IN UINT64 Arg2, IN UINT64 Arg3, IN UINT64 Arg4 ); #endif
