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.

2020-06-22cpu/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.

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.

2020-05-02acpi: Move ACPI table support out of arch/x86 (3/5)Furquan Shaikh
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. In order to make it easier to review, this change is being split into multiple CLs. This is change 3/5 which basically is generated by running the following command: $ git grep -iIl "arch/acpi" | xargs sed -i 's/arch\/acpi/acpi\/acpi/g' BUG=b:155428745 Change-Id: I16b1c45d954d6440fb9db1d3710063a47b582eae Signed-off-by: Furquan Shaikh <furquan@google.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/40938 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: HAOUAS Elyes <ehaouas@noos.fr>

At a process _start, the stack is expected to be aligned to a 16-byte boundary. Upon entry to any function the stack frame must have the end of any arguments also aligned.

Although 4-byte alignment is the minimum requirement for i386, some AMD platforms use SSE instructions which expect 16-byte. 1) http://wiki.osdev.org/System_V_ABI See "Initial Stack and Register State" and "The Stack Frame" in the supplements.

2016-03-23arch/x86: introduce postcar stage/phaseAaron Durbin
Certain chipsets don't have a memory-mapped boot media so their code execution for stages prior to DRAM initialization is backed by SRAM or cache-as-ram. The postcar stage/phase handles the cache-as-ram situation where in order to tear down cache-as-ram one needs to be executing out of a backing store that isn't transient. By current definition, cache-as-ram is volatile and tearing it down leads to its contents disappearing. Therefore provide a shim layer, postcar, that's loaded into memory and executed which does 2 things: 1. Tears down cache-as-ram with a chipset helper function. 2. Loads and runs ramstage. Because those 2 things are executed out of ram there's no issue of the code's backing store while executing the code that tears down cache-as-ram. The current implementation makes no assumption regarding cacheability of the DRAM itself. If the chipset code wishes to cache DRAM for loading of the postcar stage/phase then it's also up to the chipset to handle any coherency issues pertaining to cache-as-ram destruction.

At least on the 230, this leads to a hang on RSM, likely because both hyperthreads mess around with SMBASE and other SMM state variables in parallel without coordination. The same behaviour occurs with Atom D5xx. Change it so first APs are spun up and sent to sleep, then BSP initializes SMM, then every CPU, one after another. Only do this when SERIALIZE_SMM_INITIALIZATION is set. Set the flag for Atom CPUs.

2015-10-14x86: add standalone verstage supportAaron Durbin
To support x86 verstage one needs a working buffer for vboot. That buffer resides in the cache-as-ram region which persists across verstage and romstage. The current assumption is that verstage brings cache-as-ram up and romstage tears cache-as-ram down. The timestamp, cbmem console, and the vboot work buffer are persistent through in both romstage and verstage. The vboot work buffer as well as the cbmem console are permanently destroyed once cache-as-ram is torn down. The timestamp region is migrated. When verstage is enabled the assumption is that _start is the romstage entry point. It's currently expected that the chipset provides the entry point to romstage when verstage is employed. Also, the car_var_*() APIs use direct access when in verstage since its expected verstage does not tear down cache-as-ram. Lastly, supporting files were added to verstage-y such that an x86 verstage will build and link. BUG=chrome-os-partner:44827 BRANCH=None TEST=Built and booted glados using separate verstage.

This reverts commit a3aa8da2acec28670b724b7897ae054592746674. Chrome OS builds require the monotonic timer API in SMM for ELOG_GSMI, but sandy/ivy doesn't provide it. The commit tried to work around that by using generic LAPIC code instead, but this leads to multiple definition errors in other configurations (and it may be unreliable once the OS reconfigured the APIC timers anyhow). This fixes the situation for the non-ELOG_GSMI case (which is more or less everybody but Chrome OS). ELOG_GSMI requires a separate fix.

2015-04-06New mechanism to define SRAM/memory map with automatic bounds checkingJulius Werner
This patch creates a new mechanism to define the static memory layout (primarily in SRAM) for a given board, superseding the brittle mass of Kconfigs that we were using before. The core part is a memlayout.ld file in the mainboard directory (although boards are expected to just include the SoC default in most cases), which is the primary linker script for all stages (though not rmodules for now). It uses preprocessor macros from <memlayout.h> to form a different valid linker script for all stages while looking like a declarative, boilerplate-free map of memory addresses to the programmer. Linker asserts will automatically guarantee that the defined regions cannot overlap. Stages are defined with a maximum size that will be enforced by the linker. The file serves to both define and document the memory layout, so that the documentation cannot go missing or out of date. The mechanism is implemented for all boards in the ARM, ARM64 and MIPS architectures, and should be extended onto all systems using SRAM in the future. The CAR/XIP environment on x86 has very different requirements and the layout is generally not as static, so it will stay like it is and be unaffected by this patch (save for aligning some symbol names for consistency and sharing the new common ramstage linker script include). BUG=None TEST=Booted normally and in recovery mode, checked suspend/resume and the CBMEM console on Falco, Blaze (both normal and vboot2), Pinky and Pit.

2013-03-21ramstage: prepare for relocationAaron Durbin
The current ramstage code contains uses of symbols that cause issues when the ramstage is relocatable. There are 2 scenarios resolved by this patch: 1. Absolute symbols that are actually sizes/limits. The symbols are problematic when relocating a program because there is no way to distinguish a symbol that shouldn't be relocated and one that can. The only way to handle these symbols is to write a program to post process the relocations and keep a whitelist of ones that shouldn't be relocated. I don't believe that is a route that should be taken so fix the users of these sizes/limits encoded as absolute symbols to calculate the size at runtime or dereference a variable in memory containing the size/limit. 2. Absoulte symbols that were relocated to a fixed address. These absolute symbols are generated by assembly files to be placed at a fixed location. Again, these symbols are problematic because one can't distinguish a symbol that can't be relocated. The symbols are again resolved at runtime to allow for proper relocation. For the symbols defining a size either use 2 symbols and calculate the difference or provide a variable in memory containing the size.

This addition is in support of future multicore support in coreboot. It also will allow us to remove some asssembly code. The CPU "index" -- i.e., its order in the sequence in which cores are brought up, NOT its APIC id -- is passed into the secondary start. We modify the function to specify regparm(0). We also take this opportunity to do some cleanup: indexes become unsigned ints, not unsigned longs, for example. Build and boot on a multicore system, with pcserial enabled. Capture the output. Observe that the messages Initializing CPU #0 Initializing CPU #1 Initializing CPU #2 Initializing CPU #3 appear exactly as they do prior to this change.

2012-11-13Support better tracking of AP stack usage.Ronald G. Minnich
This change allows us to figure out how much of the AP stacks we are using, as well as to catch any case of an AP overrunning its stack. Also, the stack is poisoned, which is a good way to catch programming errors -- code should never count on auto variables being zerod. The stack bases are recorded in a new array, stacks. At the end, when all APs are initialized, the stacks are walked and the lowest level of the stack that is reached is printed. Build and boot and look for output like this: CPU1: stack allocated from 00148000 to 00148ff4:\ lowest stack address was 00148c4c CPU2: stack allocated from 00147000 to 00147ff4:\ lowest stack address was 00147c4c CPU3: stack allocated from 00146000 to 00146ff4:\ lowest stack address was 00146c4c Note that we used only about 1K of stack, even though in this case we allocated 4K (and in the main branch, we allocate 32K!)
