From 75985f1d0c47ccfcfeaecbfce869dab273b6ad71 Mon Sep 17 00:00:00 2001 From: Jonathan Zhang Date: Thu, 16 Jan 2020 11:20:09 -0800 Subject: mainboard/ocp: Add support for OCP platform TiogaPass OCP platform Tiogapass is a 2-socket server platform, which is based on a chipset including Intel Skylake-SP processors and a Lewisburg PCH. Skylake-SP is a processor in Intel Xeon Scalable Processor family. Following ACPI tables are added: DSDT/SSDT, MADT, FACP, FACS, HPET, MCFG, SLIT, SRAT, DMAR This patchset is tested on a Tiogapass board. It booted with Linux kernel 4.16.0; lscpu command shows all 72 cpus (2 sockets, 18 cores, 2 thread per core); ssh command shows networking is up from Mellanox ConnectX-4 PCIe NIC card. Towards successful gerrit buildbot build, note that: * microcode is in coreboot intel-microcode submodule repo. * IFD binary is included in this patch. * Dummy ME binary is used, as it may take long time for Intel ME binary to be available in public domain. * Fake FSP binary is used, as at this moment the SKX-SP FSP binary is not going to be available in public domain. Known issues (Not intend to address in this initial support for Xeon-SP processors): * c6 state is not supported. * dsdt table is not fully populated, such as processor/socket devices, some PCIe devices. * SMM handlers are not added. Following are some command execution with CentOS booted from local SATA disk: [root@localhost ~]# lscpu Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s): 72 On-line CPU(s) list: 0-71 Thread(s) per core: 2 Core(s) per socket: 18 Socket(s): 2 NUMA node(s): 2 Vendor ID: GenuineIntel CPU family: 6 Model: 85 Model name: Intel(R) Xeon(R) Gold 6139 CPU @ 2.30GHz Stepping: 4 CPU MHz: 140.415 BogoMIPS: 4626.46 Virtualization: VT-x L1d cache: 32K L1i cache: 32K L2 cache: 1024K L3 cache: 25344K NUMA node0 CPU(s): 0-17,36-53 NUMA node1 CPU(s): 18-35,54-71 [root@localhost ~]# ifconfig eth0: flags=4163 mtu 1500 inet 172.23.68.190 netmask 255.255.0.0 broadcast 172.23.255.255 inet6 2620:10d:c082:9063:268a:7ff:fe57:5af0 prefixlen 64 //cut inet6 fe80::268a:7ff:fe57:5af0 prefixlen 64 scopeid 0x20 inet6 2620:10d:c082:9063::5d2 prefixlen 128 scopeid 0x0 ether 24:8a:07:57:5a:f0 txqueuelen 1000 (Ethernet) RX packets 84249 bytes 6371591 (6.0 MiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 8418 bytes 748781 (731.2 KiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 lo: flags=73 mtu 65536 inet 127.0.0.1 netmask 255.0.0.0 inet6 ::1 prefixlen 128 scopeid 0x10 loop txqueuelen 1000 (Local Loopback) RX packets 613 bytes 63906 (62.4 KiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 613 bytes 63906 (62.4 KiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 [root@localhost ~]# cbmem 36 entries total: // Lines were cut to avoid checkpatch.pl warnings Total Time: 96,243,882,140,175,829 Signed-off-by: Jonathan Zhang Signed-off-by: Reddy Chagam Tested-by: johnny_lin@wiwynn.com Change-Id: I29868f03037d1887b90dfb19d15aee83c456edce Reviewed-on: https://review.coreboot.org/c/coreboot/+/38549 Tested-by: build bot (Jenkins) Reviewed-by: David Hendricks --- src/mainboard/ocp/tiogapass/fadt.c | 25 +++++++++++++++++++++++++ 1 file changed, 25 insertions(+) create mode 100644 src/mainboard/ocp/tiogapass/fadt.c (limited to 'src/mainboard/ocp/tiogapass/fadt.c') diff --git a/src/mainboard/ocp/tiogapass/fadt.c b/src/mainboard/ocp/tiogapass/fadt.c new file mode 100644 index 0000000000..6962455813 --- /dev/null +++ b/src/mainboard/ocp/tiogapass/fadt.c @@ -0,0 +1,25 @@ +/* + * This file is part of the coreboot project. + * + * Copyright (C) 2019 - 2020 Intel Corporation. + * Copyright (C) 2019 - 2020 Facebook Inc + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation; either version 2 of the License, or + * (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
