2020-07-26arch/x86: Move cpu_relax()Kyösti Mälkki
It's not related to spinlocks and the actual implementation was also guarded by CONFIG(SMP). With a single call-site in x86-specific code, empty stubs for other arch are currently not necessary. Also drop an unused included on a nearby line.

2020-07-08cpu/x86/smm: Add support for long modePatrick Rudolph
Enable long mode in SMM handler. x86_32 isn't affected by this change. As the rsm instruction used to leave SMM doesn't restore MSR registers, drop back to protected mode after running the smi_handler and restore IA32_EFER MSR (which enables long mode support) to previous value. NOTE: This commit does NOT introduce a new security model. It uses the same page tables as the remaining firmware does. This can be a security risk if someone is able to manipulate the page tables stored in ROM at runtime. USE FOR TESTING ONLY! Tested on Qemu Q35.

2020-06-23src/*: Update makefiles to exclude x86 code from psp-verstageMartin Roth
The assumption up to this point was that if the system had an x86 processor, verstage would be running on the x86 processor. With running verstage on the PSP, that assumption no longer holds true, so exclude pieces of code that cause problems for verstage on the PSP. This change will add these files to verstage only if the verstage architecture is X86 - either 32 or 64 bit.

2020-06-16Revert "x86/lapic: Set EXTINT on BSP only"Angel Pons
This reverts commit aac79e0b8f4777f8a912ccdfc483755b7a4da52c. Reason for revert: This massively slows down the boot process because the LAPIC delivery mode for the APs is not set anymore. Plus, not all review comments were fully addressed, yet this got merged in anyway.

2020-06-16x86/lapic: Set EXTINT on BSP onlyZheng Bao
When Linux is booted, the kernel reports "do_IRQ: 1.55 No irq handler for vector" So far it comes with payloads SeaBIOS and depthcharge, not with Grub. We assume Grub does something to avoid this problem. AMD bug tracker system (JIRA PLAT-21393) says the APs can not be set EXTINT delivery mode. In Intel 64 and IA-32 Architectures Software Developer’s Manual volume 3A, see chapter 10.5.1 Local Vector Table, it says: "The APIC architecture supports only one ExtINT source in a system, usually contained in the compatibility bridge. Only one processor in the system should have an LVT entry configured to use the ExtINT delivery mode." Tested on mandolin (Picasso) board, the error in dmesg is gone. The bug 153677727 has two parts. 1. Soft lockup 2. do_IRQ 1.55.

2020-06-15arch/x86: Remove XIP_ROM_SIZEKyösti Mälkki
When adding XIP stages on x86, the -P parameter was used to pass a page size that covers the entire file to add. The same can now be achieved with --pow2page and we no longer need to define a static Konfig for the purpose. TEST: Build asus/p2b and lenovo/x60 with "--pow2page -v -v" and inspect the generated make.log files. The effective pagesize is reduced from 64kB to 16kB for asus/p2b giving more freedom for the stage placement inside CBFS. Pagesize remained at 64kB for lenovo/x60.

This change moves all ACPI table support in coreboot currently living under arch/x86 into common code to make it architecture independent. ACPI table generation is not really tied to any architecture and hence it makes sense to move this to its own directory.

2020-05-01cpu/x86/mtrr/earlymtrr: Validate MTRR argumentsRaul E Rangel
The AMD64 Architecture Programmer's Manual, Volume 2: Systems Programming says the following about variable MTRRs: Variable Range Size and Alignment. The size and alignment of variable memory-ranges (MTRRs) and I/O ranges (IORRs) are restricted as follows: * The boundary on which a variable range is aligned must be equal to the range size. For example, a memory range of 16 Mbytes must be aligned on a 16-Mbyte boundary (i.e., naturally aligned). * The range size must be a power of 2 (2^n , 52 > n > 11), with a minimum allowable size of 4 Kbytes. For example, 4 Mbytes and 8 Mbytes are allowable memory range sizes, but 6 Mbytes is not allowable. Print out errors if these conditions are violated. I didn't assert since `set_var_mtrr` can be used in boot block before the serial console is enabled.

They're listed in AUTHORS and often incorrect anyway, for example: - What's a "Copyright $year-present"? - Which incarnation of Google (Inc, LLC, ...) is the current copyright holder? - People sometimes have their editor auto-add themselves to files even though they only deleted stuff - Or they let the editor automatically update the copyright year, because why not? - Who is the copyright holder "The coreboot project Authors"? - Or "Generated Code"? Sidestep all these issues by simply not putting these notices in individual files, let's list all copyright holders in AUTHORS instead and use the git history to deal with the rest.

2020-02-17cpu/x86: Adjust STM smm_save_state_sizeEugene Myers
Initial testing of STM support revealed a sizing issue for greater than 4 threads. This patch reduces the STM smm_save_state_size, which should allow for 24 threads. 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.

2020-02-04cpu/x86: Make MP init timeout configurableJonathan Zhang
The current MP init timeout is hardcoded as 1s. To support platform with many cpus, the timeout needs to be adjusted. The number of cpus is calculated as: number of sockets * number of cores per socket * number of threads per core How long the timeout should be set to, is heuristic. It needs to be set long enough to ensure reboot stability, but not unreasonable so that real failures can be detected soon enough, especially for smaller systems. This patch sets timeout to be minimum as 1 second, while each cpu adds 0.1 second.
