| * platform/x86: ISST: Support partitioned systemsSrinivas Pandruvada2024-04-291-32/+267
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A partitioned system has two different PCI VSEC devices per package. A non-partitioned device has only one PCI VSEC device per package. The current implementation only supports non partitioned systems. Each partition maps a set of power domains. Other than reading from different MMIO regions, there is no change in the SST functionality. The scope of SST control is still per power domain. Hence user space does not need to be aware of existence of partitions. With partitions, existing per package information defined using struct tpmi_sst_struct is enhanced to store information for both partitions. A mapping function map_partition_power_domain_id() is introduced, which maps to correct partition and index. This mapping function is called in get_instance() and isst_if_clos_assoc(), before indexing into tpmi_sst_struct->power_domain_info[]. The TPMI core platform info provides partition id and compute die ID mask for each partition. Use this information to order power domains, so that compute dies are presented before IO dies to match hardware defined compute die ID for each CPU.

Some of the reserved fields in version 1 are used to define new fields. Parse new fields and export as part of platform data. These fields include: - PCI segment ID - Partition ID of the package: If a package is represented by more than one PCI device, then partition ID along with cdie_mask, describes the scope. For example to update get/set properties for a compute die, one of the PCI MMIO region is selected from the partition ID. - cdie_mask: Mask of all compute dies in this partition.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | One of the stages in IFS image loading process involves loading individual chunks (test patterns) from test image file to secure memory. Driver issues a WRMSR(MSR_AUTHENTICATE_AND_COPY_CHUNK) operation to do this. This operation can take up to 5 msec, and if an interrupt occurs in between, the AUTH_AND_COPY_CHUNK u-code implementation aborts the operation. Interrupt sources such as NMI or SMI are handled by retrying. Regular interrupts may occur frequently enough to prevent this operation from ever completing. Disable irq on local cpu around the aforementioned WRMSR to allow the operation to complete.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "Scan controller error" means that scan hardware encountered an error prior to doing an actual test on the target CPU. It does not mean that there is an actual cpu/core failure. "scan signature failure" indicates that the test result on the target core did not match the expected value and should be treated as a cpu failure. Current driver classifies both these scenarios as failures. Modify the driver to classify this situation with a more appropriate "untested" status instead of "fail" status.

To debug PKGC-10 issues, we also need to know other PKGC residency counters to better triage issues. Ex: 1. When system is stuck in PC2, it can be caused short LTR from device. 2. When system is stuck in PC8, it can be caused by display engine. To better triage issues, all PKGC residency are needed when issues happen. Example log: CPU did not enter Package C10!!! (Package C10 cnt=0x0) Prev Package C2 cnt = 0x2191a325de, Current Package C2 cnt = 0x21aba30724 Prev Package C3 cnt = 0x0, Current Package C3 cnt = 0x0 Prev Package C6 cnt = 0x0, Current Package C6 cnt = 0x0 Prev Package C7 cnt = 0x0, Current Package C7 cnt = 0x0 Prev Package C8 cnt = 0x0, Current Package C8 cnt = 0x0 Prev Package C9 cnt = 0x0, Current Package C9 cnt = 0x0 Prev Package C10 cnt = 0x0, Current Package C10 cnt = 0x0 With this log, we can know whether it's a stuck PC2 issue, and we can check whether the short LTR from device causes the issue.

If the other sibling was in mwait(), that didn't permit the test to complete and resulted in several retries before the test could finish. The exit rendezvous was introduced to keep the HT sibling busy until the primary CPU completed the test to avoid those retries. What is actually needed is to ensure that both the threads rendezvous *before* the wrmsr to trigger the test to give good chance to complete the test. The `stop_machine()` function returns only after all the CPUs complete running the function, and provides an exit rendezvous implicitly. In kernel/stop_machine.c::multi_cpu_stop(), every CPU in the mask needs to complete reaching MULTI_STOP_RUN. When all CPUs complete, the state machine moves to next state, i.e MULTI_STOP_EXIT. Thus the underlying API stop_core_cpuslocked() already provides an exit rendezvous. Add the rendezvous earlier in order to ensure the wrmsr is triggered after all CPUs reach the do_array_test(). Remove the exit rendezvous since stop_core_cpuslocked() already guarantees that.
