fix #29415191 commit 17fae1294ad9d711b2c3dd0edef479d40c76a5e8 upstream An interesting thing happened when a guest Linux instance took a machine check. The VMM unmapped the bad page from guest physical space and passed the machine check to the guest. Linux took all the normal actions to offline the page from the process that was using it. But then guest Linux crashed because it said there was a second machine check inside the kernel with this stack trace: do_memory_failure set_mce_nospec set_memory_uc _set_memory_uc change_page_attr_set_clr cpa_flush clflush_cache_range_opt This was odd, because a CLFLUSH instruction shouldn't raise a machine check (it isn't consuming the data). Further investigation showed that the VMM had passed in another machine check because is appeared that the guest was accessing the bad page. Fix is to check the scope of the poison by checking the MCi_MISC register. If the entire page is affected, then unmap the page. If only part of the page is affected, then mark the page as uncacheable. This assumes that VMMs will do the logical thing and pass in the "whole page scope" via the MCi_MISC register (since they unmapped the entire page).

fix #29035143 commit 2c18bd525c47f882f033b0a813ecd09c93e1ecdf upstream Memory bandwidth is calculated reading the monitoring counter at two intervals and calculating the delta. It is the software’s responsibility to read the count often enough to avoid having the count roll over _twice_ between reads. The current code hardcodes the bandwidth monitoring counter's width to 24 bits for AMD. This is due to default base counter width which is 24. Currently, AMD does not implement the CPUID 0xF.[ECX=1]:EAX to adjust the counter width. But, the AMD hardware supports much wider bandwidth counter with the default width of 44 bits. Kernel reads these monitoring counters every 1 second and adjusts the counter value for overflow. With 24 bits and scale value of 64 for AMD, it can only measure up to 1GB/s without overflowing. For the rates above 1GB/s this will fail to measure the bandwidth. Fix the issue setting the default width to 44 bits by adjusting the offset. AMD future products will implement CPUID 0xF.[ECX=1]:EAX.

to #26613714 commit 4d05bf71f157d756932e77cdee16dc99e235d636 upstream. Enable QOS feature on AMD. Following QoS sub-features are supported on AMD if the underlying hardware supports it: - L3 Cache allocation enforcement - L3 Cache occupancy monitoring - L3 Code-Data Prioritization support - Memory Bandwidth Enforcement (Allocation) The specification is available at: https://developer.amd.com/wp-content/resources/56375.pdf There are differences in the way some of the features are implemented. Separate those functions and add those as vendor specific functions. The major difference is in MBA feature: - AMD uses CPUID leaf 0x80000020 to initialize the MBA features. - AMD uses direct bandwidth value instead of delay based on bandwidth values. - MSR register base addresses are different for MBA. - AMD allows non-contiguous L3 cache bit masks.

to #26613714 commit 1ad4fa41d99f606098fd7b90c1f5deb2b3dfae5d upstream. Initialize the resource functions that are different between the vendors. Some features are initialized differently between the vendors. Add _intel suffix to Intel-specific functions. For example, the MBA feature varies significantly between Intel and AMD. Separate the initialization of these resource functions. That way we can easily add AMD's functions later.

With more than one vendors supporting these features, it seems more appropriate to rename these files.

commit e0ceeae708cebf22c990c3d703a4ca187dc837f5 upstream. The Hygon family 18h multi-die processor platform supports 1, 2 or 4-Dies per socket. The topology looks like this: System View (with 1-Die 2-Socket): |------------| ------ ----- SOCKET0 | D0 | | D1 | SOCKET1 ------ ----- System View (with 2-Die 2-socket): -------------------- | -------------|------ | | | | ------------ ------------ SOCKET0 | D1 -- D0 | | D3 -- D2 | SOCKET1 ------------ ------------ System View (with 4-Die 2-Socket) : -------------------- | -------------|------ | | | | ------------ ------------ | D1 -- D0 | | D7 -- D6 | | | \/ | | | | \/ | | SOCKET0 | | /\ | | | | /\ | | SOCKET1 | D2 -- D3 | | D4 -- D5 | ------------ ------------ | | | | ------|------------| | -------------------- Currently phys_proc_id = initial_apicid >> bits calculates the physical processor ID from the initial_apicid by shifting *bits*. However, this does not work for 1-Die and 2-Die 2-socket systems. According to document [1] section 2.1.11.1, the bits is the value of CPUID_Fn80000008_ECX[12:15]. The possible values are 4, 5 or 6 which mean: 4 - 1 die 5 - 2 dies 6 - 3/4 dies. Hygon programs the initial ApicId the same way as AMD. The ApicId is read from CPUID_Fn00000001_EBX (see section 2.1.11.1 of referrence [1]) and the definition is as below (see section 2.1.10.2.1.3 of [1]): ------------------------------------------------- Bit | 6 | 5 4 | 3 | 2 1 0 | |-----------|---------|--------|----------------| IDs | Socket ID | Node ID | CCX ID | Core/Thread ID | ------------------------------------------------- So for 3/4-Die configurations, the bits variable is 6, which is the same as the ApicID definition field. For 1-Die and 2-Die configurations, bits is 4 or 5, which will cause the right shifted result to not be exactly the value of socket ID. However, the socket ID should be obtained from ApicId[6]. To fix the problem and match the ApicID field definition, set the shift bits to 6 for all Hygon family 18h multi-die CPUs. Because AMD doesn't have 2-Socket systems with 1-Die/2-Die processors (see reference [2]), this doesn't need to be changed on the AMD side but only for Hygon.

commit 6d0ef316b9f8ea03fa867debda70b2f11a0b9736 upstream. The PMU architecture for the Hygon Dhyana CPU is similar to the AMD Family 17h one. To support it, call amd_pmu_init() to share the AMD PMU initialization flow, and change the PMU name to "HYGON". The Hygon Dhyana CPU supports both legacy and extension PMC MSRs (perf counter registers and event selection registers), so add Hygon Dhyana support in the similar way as AMD does.

commit 39dc6f154dac134e4612827cb5283934c1862cb8 upstream. The Hygon Dhyana CPU has a special MSR way to force WB for memory >4GB, and support TOP_MEM2. Therefore, it is necessary to add Hygon Dhyana support in amd_special_default_mtrr(). The number of variable MTRRs for Hygon is 2 as AMD's.

commit d4f7423efdd1419b17524d090ff9ff4024bcf09b upstream. The Hygon Dhyana CPU has a topology extensions bit in CPUID. With this bit, the kernel can get the cache information. So add support in cpuid4_cache_lookup_regs() to get the correct cache size. The Hygon Dhyana CPU also discovers num_cache_leaves via CPUID leaf 0x8000001d, so add support to it in find_num_cache_leaves(). Also add cacheinfo_hygon_init_llc_id() and init_hygon_cacheinfo() functions to initialize Dhyana cache info. Setup cache cpumap in the same way as AMD does.

commit c9661c1e80b609cd038db7c908e061f0535804ef upstream. Add x86 architecture support for a new processor: Hygon Dhyana Family 18h. Carve out initialization code needed by Dhyana into a separate compilation unit. To identify Hygon Dhyana CPU, add a new vendor type X86_VENDOR_HYGON. Since Dhyana uses AMD functionality to a large degree, select CPU_SUP_AMD which provides that functionality.

commit 3ad7e748c12cc771df6020a552def3e1727e8a17 upstream. The existing CS, PSP, and SMU SMCA bank types will see new versions (as indicated by their McaTypes) in future SMCA systems. Add the new (HWID, MCATYPE) tuples for these new versions. Reuse the same names as the older versions, since they are logically the same to the user. SMCA systems won't mix and match IP blocks with different McaType versions in the same system, so there isn't a need to distinguish them. The MCA_IPID register is saved when logging an MCA error, and that can be used to triage the error. Also, add the new error descriptions to edac_mce_amd. Some error types (positions in the list) are overloaded compared to the previous McaTypes. Therefore, just create new lists of the error descriptions to keep things simple even if some of the error descriptions are the same between versions.

commit 556e4c62baffa71e2045a298379db7e57dd47f3d upstream. Add support for new processors which have multiple PCI root complexes per data fabric/system management network interface. If there are (N) multiple PCI roots per DF/SMN interface, then the PCI roots are redundant (as far as SMN/DF access goes). For each DF/SMN interface: map to the first available PCI root and skip the next N-1 PCI roots so the following DF/SMN interface get mapped to a correct PCI root.
