2020-06-22cpu/x86/lapic: Support x86_64 and clean up codePatrick Rudolph
Most LAPIC registers are 32bit, and thus the use of long is valid on x86_32, however it doesn't work on x86_64. * Don't use long as it is 64bit on x86_64, which breaks interrupts in QEMU and thus SeaBIOS wouldn't time out the boot menu * Get rid of unused defines * Get rid of unused atomic xchg code Tested on QEMU Q35 with x86_64 enabled: Interrupts work again. Tested on QEMU Q35 with x86_32 enabled: Interrupts are still working. Tested on Lenovo T410 with x86_64 enabled.

According to the comments of https://review.coreboot.org/c/coreboot/+/41719 , which is about Microcode patch for amd/picasso. Change the code with the same way. The changes include: 1. combine the microcode_xxx.c and update_microcode.c into one source. 2. Redefine the microcode updating function to eliminate the parameter. Get the revision ID in the black box. Reduce the depth of function calls. 3. Get the revision ID by bitwise calculation instead of lookup table. 4. Reduce the confusing type casts. 5. Squash some lines. We do not change the way it used to be. The code assume only one microcode is integrated in CBFS. If needed in future, 41719 is the example of integrating multiple binaries. And, 41719 depends on the definition in this patch.

2020-03-07cpu/x86/smm: Add smm_size to relocatable smmstubArthur Heymans
To mitigate against sinkhole in software which is required on pre-sandybridge hardware, the smm entry point needs to check if the LAPIC base is between smbase and smbase + smmsize. The size needs to be available early so add them to the relocatable module parameters. When the smmstub is used to relocate SMM the default SMM size 0x10000 is provided. On the permanent handler the size provided by get_smm_info() is used.

2020-02-21security/intel/stm: Check for processor STM supportEugene Myers
Check to ensure that dual monitor mode is supported on the current processor. Dual monitor mode is normally supported on any Intel x86 processor that has VTx support. The STM is a hypervisor that executes in SMM dual monitor mode. This check should fail only in the rare case were dual monitor mode is disabled. If the check fails, then the STM will not be initialized by coreboot. Signed-off-by: Eugene D.

2020-02-05security/intel/stm: Add STM supportEugene Myers
This update is a combination of all four of the patches so that the commit can be done without breaking parts of coreboot. This possible breakage is because of the cross-dependencies between the original separate patches would cause failure because of data structure changes. security/intel/stm This directory contains the functions that check and move the STM to the MSEG, create its page tables, and create the BIOS resource list. The STM page tables is a six page region located in the MSEG and are pointed to by the CR3 Offset field in the MSEG header. The initial page tables will identity map all memory between 0-4G. The STM starts in IA32e mode, which requires page tables to exist at startup. The BIOS resource list defines the resources that the SMI Handler is allowed to access. This includes the SMM memory area where the SMI handler resides and other resources such as I/O devices. The STM uses the BIOS resource list to restrict the SMI handler's accesses. The BIOS resource list is currently located in the same area as the SMI handler. This location is shown in the comment section before smm_load_module in smm_module_loader.c Note: The files within security/intel/stm come directly from their Tianocore counterparts. Unnecessary code has been removed and the remaining code has been converted to meet coreboot coding requirements.

2019-11-03cpu/x86/tsc: Flip and rename TSC_CONSTANT_RATE to UNKNOWN_TSC_RATEKyösti Mälkki
The x86 timers are a bit of a mess. Cases where different stages use different counters and timestamps use different counters from udelays. The original intention was to only flip TSC_CONSTANT_RATE Kconfig to NOT_CONSTANT_TSC_RATE. The name would be incorrect though, those counters do run with a constant rate but we just lack tsc_freq_mhz() implementation for three platforms. Note that for boards with UNKNOWN_TSC_RATE=y, each stage will have a slow run of calibrate_tsc_with_pit(). This is easy enough to fix with followup implementation of tsc_freq_mhz() for the platforms. Implementations with LAPIC_MONOTONIC_TIMER typically will not have tsc_freq_mhz() implemented and default to UNKNOWN_TSC_RATE. However, as they don't use TSC for udelay() the slow calibrate_tsc_with_pit() is avoided. Because x86/tsc_delay.tsc was using two different guards and nb/via/vx900 claimed UDELAY_TSC, but pulled UDELAY_IO implementation, we also switch that romstage to use UDELAY_TSC.
