2022-06-13core: detect LPAR-per-core mode and report in dtNicholas Piggin2-0/+4
Some firmware configurations boot in LPAR-per-core mode, which is not compatible with KVM on POWER9 and later machines. Detect which LPAR mode the boot core is in (all others will be set the same way), and if booted in LPAR-per-core mode then print a warning and add a device-tree entry that the OS can test for.

2021-11-10hdata: add mmu-pid-bits and mmu-lpid-bits for POWER10 CPUsNicholas Piggin1-0/+4
This adds ibm,mmu-pid-bits and a new ibm,mmu-lpid-bits to POWER10 CPUs. POWER9 Linux has some workarounds for processors bugs that means it's probably safer to not add the entries there. Linux already hard codes these values correctly on these processors, but this allows more flexibility to change things.

2021-10-19pau: introduce supportChristophe Lombard2-8/+25
OpenCapi for P10 is included in the P10 chip. This requires OCAPI capable PHYs, Datalink Layer Logic and Transaction Layer Logic to be included. The PHYs are the physical connection to the OCAPI interconnect. The Datalink Layer provides link training. The Transaction Layer executes the cache coherent and data movement commands on the P10 chip. The PAU provides the Transaction Layer functionality for the OCAPI link(s) on the P10 chip. The P10 PAU supports two OCAPI links. Six accelerator units PAUs are instantiated on the P10 chip for a total of twelve OCAPI links. This patch adds PAU opencapi structure for supporting OpenCapi5. hw/pau.c file contains main of PAU management functions.

This fixes multipchip rainier boot issue. for Rainer: chip0: ibm,primary-topology-index = < 0x0>; chip1: ibm,primary-topology-index = < 0x4>; chip2: ibm,primary-topology-index = < 0x8>; chip3: ibm,primary-topology-index = < 0xc>; for Denali: node0: chip0: ibm,primary-topology-index = < 0x0>; chip1: ibm,primary-topology-index = < 0x1>; chip2: ibm,primary-topology-index = < 0x2>; chip3: ibm,primary-topology-index = < 0x3>; node1: chip0: ibm,primary-topology-index = < 0x4>; chip1: ibm,primary-topology-index = < 0x5>; chip2: ibm,primary-topology-index = < 0x6>; chip3: ibm,primary-topology-index = < 0x7>; Note that bmc_create_node() gets called very early in the boot process. Hence we have to traverse through HDAT ntuple to get right topology index. May be we can optimize pcid_to_topology_idx() function as its pretty much duplicate of pcid_to_chip_id(). But for now lets keep it as separate function.

2021-08-06hdat/spira: Define ibm, primary-topology-index property per chipHaren Myneni2-1/+16
HDAT provides Topology ID table and the primary topology location on P10. This primary location points to primary topology entry in ID table which contains the primary topology index and this index is used to define the paste base address per chip. This patch reads Topology ID table and the primary topology location from hdata and retrieves the primary topology index in the ID table. Make this primaty topology index value available with ibm,primary-topology-index property per chip. VAS reads this property to setup paste base address for each chip.

2020-08-07Add basic P9 fused core supportRyan Grimm1-1/+8
P9 cores can be configured into fused core mode where two core chiplets function as an 8-threaded, single core. So, bump four to eight in boot_entry when in fused core mode and cpu_thread_count in init_boot_cpu. The HID, AMOR, TSCR, RPR require the first active thread on that core chiplet to load the copy for that core chiplet. So, send thread 1 of a fused core to init_shared_sprs in boot_entry. The code checks for fused core mode in the core thead state register and puts a field in struct cpu_thread. This flag is checked when updating the HID and in XIVE code when setting the special bar. For XSCOM, the core ID is the non-fused EX. So, create macros to arrange the bits. It's fairly verbose but somewhat readable. This was tested on a P9 ZZ with 16 fused cores and ran HTX for over 24 hours.

We are using SAI indicator location from SLCA to represent System Attention Indicator location code. In P9, this is mapped to op-panel location code. op-panel has identify and fault LEDs as well. Our SPCN command lists op-panel location code as well. Hence we get below OPAL warning. OPAL msglog: FSPLED: duplicate location code U78D3.001.WT0004T-D1 Because of above issue we are not creating device tree node for D1 identify/fault indicators. We have System Attention Indicator at enclosure level as well.. which is replica of attention indicator in op-panel. Hence use System VPD location code to represent attention indicator. Note that we have dedicated MBOX command to read/update System Attention Indicator which doesn't need location code. Hence we are fine with this change.

2020-04-08hdata/memory: Add support for memory-buffer mmioOliver O'Halloran1-14/+125
HDAT now allows associating a set of MMIO address ranges with an MSAREA. This is to allow for exporting the MMIO register space associated with a memory-buffer chip to the hypervisor so we can wire up access to that for PRD. The DT format is similar to the old centaur memory-buffer@<addr> nodes that we had on P8 OpenPower systems. The biggest difference is that the HDAT format allows for multiple memory ranges on each "chip" and each of these ranges may have a different register size.

2019-11-14tests: Squash __attrconst related warningsOliver O'Halloran1-4/+2
Currently we get a warning because in some of the test stub functions: [ HOSTCC ] hw/test/phys-map-test.c In file included from hw/test/phys-map-test.c:8: hw/test/../../core/test/stubs.c:78:1: warning: ‘const’ attribute on function returning ‘void’ [-Wattributes] 78 | { | ^ I'm pretty sure we added that __attrconst to squash a warning with an earlier GCC, then they went an added a warning for the "fix."

2019-11-11Remove dead POWER7 codeNicholas Piggin9-441/+39
There are a number of proc_gen branches removed that are trivially dead code and comments that refer to P7. As well as those: - Oliver points out that add_xics_icps() must be unused on POWER8 because it asserts if number of threads > 4, so remove it. - Change 16b7ae641 ("Remove POWER7 and POWER7+ support") removed all references to opal_boot_trampoline, so remove that. - It also removed the only non-trival choose_bus implementation, so that is removed and its caller simplified. - Remove the paca code, later CPUs use pcia.

2019-11-05hdata: Fix reserved node label searchVasant Hegde1-3/+7
Soon hostboot/HDAT will provide consistent reserved node name. It will just provide node name without starting string "ibm,". Commit 50d508c3 made sure that all device tree nodes starts with "ibm,". But we use hostboot/HDAT provided name for `ibm,prd-label` property. So we have to fix couple of our `ibm,prd-label` property based search/comparision to accommodate this change.

One of the spira structs (iplparams_sysparams) captures different system bus speeds/frequency. Patch exports the same in "sys-params" dt node. These values will help in nest pmu metric calculations. ABC bus speed values are exported in "abc-bus-freq-mhz" property. As name suggest, values are in MHz. WXYZ bus speed values are exported in "wxyz-bus-freq-mhz" property.

2019-08-15MPIPL: Reserve memory to capture architected registers dataVasant Hegde1-0/+7
- Split SPIRAH memory to accommodate architected register ntuple. Today we have 1K memory for SPIRAH and it uses 288 bytes. Lets split this into two parts : SPIRAH (756 bytes) architected register memory (256 bytes) - Update SPIRAH architected register ntuple - Calculate memory required to capture architected registers data Ideally we should use HDAT provided data (proc_dump_area->thread_size). But we are not getting this data during boot. Hence lets reserve fixed memory for architected registers data collection. - Add architected registers destination memory to reserve-memory DT node.

2019-08-15hdata: Create /ibm, opal/dump device tree nodeVasant Hegde2-0/+22
We use MPIPL system parameter to detect whether MPIPL is supported or not. If its supported create new device tree node (/ibm,opal/dump) to pass all dump related information to kernel. This patch creates new node and populates below properties: - compatible - dump version (ibm,opal-dump) - fw-load-area - Memory used by OPAL to load kernel/initrd from PNOR (KERNEL_LOAD_BASE & INITRAMFS_LOAD_BASE). This is the temporary memory used by OPAL during boot. Later Linux kernel is free to use this memory. During MPIPL boot also OPAL will overwrite this memory. OPAL will advertise these memory details to kernel. If kernel is using these memory and needs these memory content for proper dump creation, then it has to reserve destination memory to preserve these memory ranges. Also kernel should pass this detail during registration. During MPIPL firmware will take care of preserving memory and post MPIPL kernel can create proper dump.
