config SOC_INTEL_COMMON_BLOCK_CPU
bool
default n
help
This option selects Intel Common CPU Model support code
which provides various CPU related APIs which are common
between all Intel Processor families. Common CPU code is supported
for SOCs starting from SKL,KBL,APL, and future.
config SOC_INTEL_COMMON_BLOCK_CPU_MPINIT
bool
default n
help
This option selects Intel Common CPU MP Init code. In
this common MP Init mechanism, the MP Init is occurring before
calling FSP Silicon Init. Hence, MP Init will be pulled to
BS_DEV_INIT_CHIPS Entry. And on Exit of BS_DEV_INIT, it is
ensured that all MTRRs are re-programmed based on the DRAM
resource settings.
config SOC_INTEL_COMMON_BLOCK_CAR
bool
default n
help
This option allows you to select how cache-as-ram (CAR) is set up.
config INTEL_CAR_NEM
bool
default n
help
Traditionally, CAR is set up by using Non-Evict mode. This method
does not allow CAR and cache to co-exist, because cache fills are
blocked in NEM.
config INTEL_CAR_CQOS
bool
default n
help
Cache Quality of Service allows more fine-grained control of cache
usage. As result, it is possible to set up a portion of L2 cache for
CAR and use the remainder for actual caching.
config INTEL_CAR_NEM_ENHANCED
bool
default n
help
A current limitation of NEM (Non-Evict mode) is that code and data sizes
are derived from the requirement to not write out any modified cache line.
With NEM, if there is no physical memory behind the cached area,
the modified data will be lost and NEM results will be inconsistent.
ENHANCED NEM guarantees that modified data is always
kept in cache while clean data is replaced.
config USE_CAR_NEM_ENHANCED_V1
bool
select INTEL_CAR_NEM_ENHANCED
help
This config supports INTEL_CAR_NEM_ENHANCED mode on
SKL, KBL, CNL, WHL, CML and ICL and JSL platforms.
config USE_CAR_NEM_ENHANCED_V2
bool
select INTEL_CAR_NEM_ENHANCED
select COS_MAPPED_TO_MSB
help
This config supports INTEL_CAR_NEM_ENHANCED mode on
TGL platform.
config COS_MAPPED_TO_MSB
bool
depends on INTEL_CAR_NEM_ENHANCED
help
On TGL and JSL platform the class of service configuration
is mapped to MSB of MSR IA32_PQR_ASSOC.
config USE_INTEL_FSP_MP_INIT
bool "Perform MP Initialization by FSP"
default n
depends on !USE_INTEL_FSP_TO_CALL_COREBOOT_PUBLISH_MP_PPI
help
This option allows FSP to perform multiprocessor initialization.
config USE_INTEL_FSP_TO_CALL_COREBOOT_PUBLISH_MP_PPI
bool "Perform MP Initialization by FSP using coreboot MP PPI service"
depends on FSP_USES_MP_SERVICES_PPI
default y if FSP_PEIM_TO_PEIM_INTERFACE
default n
help
This option allows FSP to make use of MP services PPI published by
coreboot to perform multiprocessor initialization.
config INTEL_TME
bool "Total Memory Encryption (TME)/Multi-key TME (MKTME)"
default n
help
Enable Total Memory Encryption (TME)/Multi-key TME (MKTME). The spec is
available at "https://software.intel.com/sites/default/files/managed/a5
/16/Multi-Key-Total-Memory-Encryption-Spec.pdf". If CPU supports TME,
it would get enabled. If CPU supports MKTME, this same config option
enables MKTME.
