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:
