The CPU driver should select this if the CPU needs
to execute an lfence instruction in order to synchronize
rdtsc. This is true for all modern AMD CPUs.

The CPU driver should select this if the CPU needs
to execute an mfence instruction in order to synchronize
rdtsc. This is true for all modern Intel CPUs.

When selected a variable range MTRR is allocated for coreboot and
the bootloader enables caching of the system ROM for faster access.

x86: SMM Module Support Add support for SMM modules by leveraging the RMODULE lib. This allows for easier dynamic SMM handler placement. The SMM module support consists of a common stub which puts the executing CPU into protected mode and calls into a pre-defined handler. This stub can then be used for SMM relocation as well as the real SMM handler. For the relocation one can call back into coreboot ramstage code to perform relocation in C code. The handler is essentially a copy of smihandler.c, but it drops the TSEG differences. It also doesn't rely on the SMM revision as the cpu code should know what processor it is supported. Ideally the CONFIG_SMM_TSEG option could be removed once the existing users of that option transitioned away from tseg_relocate() and smi_get_tseg_base(). The generic SMI callbacks are now not marked as weak in the declaration so that there aren't unlinked references. The handler has default implementations of the generic SMI callbacks which are marked as weak. If an external compilation module has a strong symbol the linker will use that instead of the link one. Additionally, the parameters to the generic callbacks are dropped as they don't seem to be used directly. The SMM runtime can provide the necessary support if needed.

bool
default n
depends on HAVE_SMI_HANDLER
select RELOCATABLE_MODULES
help
If SMM_MODULES is selected then SMM handlers are built as modules.
A SMM stub along with a SMM loader/relocator. All the handlers are
written in C with stub being the only assembly.
config SMM_MODULE_HEAP_SIZE

help
This option determines the size of the heap within the SMM handler
modules.
config X86_AMD_FIXED_MTRRS
bool
default n
help
This option informs the MTRR code to use the RdMem and WrMem fields
in the fixed MTRR MSRs.
